Fish Protein Concentrate
(FPC)

• Protein malnutrition as is being experienced all over the world has been
attracting the attention of nutritionists and others since quite sometime
and much effort has already been expended in this field.
• Production of inexpensive and at the same time nutritious food can do
much to tackle this problem and free the millions out of this grave
situation.
• In the opinion of experts fish is considered to be the ultimate answer to this
burning problem mainly because of its abundance in nature, cheapness and
high nutritive value . The main consideration is how to make fish which is
highly perishable useful for the purpose.

• Fish protein concentrate (FPC) is defined in various ways. One of these is "Fish
protein concentrate is any low cost, stable, wholesome product of high nutritive
quality, hygienically prepared from fish, in which the protein and other nutrient
materials are more concentrated than they were in the fresh fish.
• The characteristics of the products may range from tasteless, odorless, light-
colored, flour-like materials to colored products having a slightly fishy taste and
odor. This concentrated protein can be used as a supplement in human diets to
combat protein malnutrition. Dr Sameer G Chebbi 4

Fish Protein Concentrate

• Type-C protein concentrate is a fish meal that has been prepared
under sanitary conditions and meeting the FAO requirement for
freedom from pathogenic organism.
• As prepared commercially ,this product would be considerably lower
in cost than those prepared by more sophisticated means.
• They would normally have a strong flavor and odor that is usually
limit their acceptance even when added to food at a low level.
• However not every one object to those fishy odor and flavor

• Processing consist of-
• Dressing
• Cooking
• Separation of oil by pressing and mincing of cooked flesh
• Drying in a tunnel drier at a temperature of 60- 70 degree Celsius and
• Packaging in a tin container preferably under carbon dioxide or
vacuum.

• There are five main technical objectives-
• First is to removed water.
• Second is to removed all or most of the fish lipid.
• Third is to retain the nutritive value of the protein during process.
• Fourth is to ensure the safety of final product.
• Fifth is the economic objective of manufacturing.

• Fish protein concentrates (FPC's) are defined as those products
obtained from fish in which the protein is more concentrated than in
the original raw material.
• Both powders and pastes may be water soluble or insoluble and may
be high in nutritive value or only intermediate in nutritive value.

• According to the FAO there are three major types of fish protein
concentrates (FPC):
• Type A: a virtually odourless and tasteless powder having a maximum total
fat content of 0.75%.
• Type B: a powder having no specific limits as to odour or flavour, but
definitely having a fishy flavour and a maximum fat content of 3%.
• Type C: normal fish meal produced under satisfactorily hygienic conditions.

• The fat content is specified when defining types of FPC because fat when
oxidised can produce a strong, often rancid, taste in the product.
• The protein content of FPC depends on the raw material used and the
extent to which water has been removed, but the products normally
contain at least 65 percent protein and, in type A, up to 80 per cent.
• Other types of fish protein concentrates such as fish protein hydrolysates
are not included in the above definition.

• For this purpose, various methods have been developed to prepare FPC for
human consumption.
• These methods can be placed under three main divisions. These are:
• (A) physical methods,
• (B) solvent extraction methods and
• (C) hydrolysis of fish.
• The combination of any two of these methods or all of the three methods
may increase the efficiency of the process.

• A. Physical Methods
• On the basis of this method, FPC plants have been set up in those plants
fresh fish is autoclaved, the cooked fish is pressed to remove fish solubles
and lipids, and the press cake is dried, ground and packed in suitable sizes.

• B. Solvent Extraction Methods
• These methods are widely used in the developed and developing countries
like Canada, Chile, France, Germany, India, Japan, Mexico, Panama, Peru,
Scandinavian countries, South Africa, The United Kingdom, The United
States df America, and Uruguay.
• The application of physical processes such as raising the temperature,
stirring, filtration, pressing, distillation, vacuum drying, etc., increases the
efficiency of the process.

• C. Hydrolytic Methods (The hydrolytic process for the preparation of FPC.)
• Two types of hydrolysis have so far been tried.
• These are (1) chemical hydrolysis and (2) enzymatic hydrolysis.
• (1) Chemical Hydrolysis In this process whole fish is hydrolyzed chemically.
The hydrolyzed product is filtered through a filter press to separate
undissolved bones, skin and scale from protein solution. The filtrate is
concentrated to about 50% solid and spray dried.

• (2) Enzymatic Hydrolysis
• The process is identical to the chemical hydrolysis process, except that a
proteolytic enzyme or a suitable microorganism is used in place of
chemicals and the pH, temperature and concentration of the reacting
media are controlled to achieve maximum activity of the enzymes.

B. Solvent Extraction Methods
PREPARATION OF THE FLOUR
• The fish after mincing is suspended in an equal amount of water to which has
been added 0.5% acetic acid and kept at 70-80°C. for 30 minutes under constant
stirring.
• The slurry is filtered and pressed in a screw press so that a good amount of liquid
is removed.
• The press cake will contain nearly 60-62% moisture. It is then dried in a tunnel
dryer at a temperature range of 75-80°C. to various levels of moisture.
• The dry matter (moisture content below 10%) is coarsely ground in an ordinary
milling machine and used for extraction of fat.

• EXTRACTION
• The material is charged in to the extraction drum having arrangements for stirring and
refluxing.
• The solvent, mixture of hexane and ethyl alcohol is added in two parts by volume to one
part by weight of material and kept at the boiling temperature of the solvent for 30
minutes, under constant stirring.
• The solvent is drained off and fresh solvent added in 1.5 parts by volume to one part by
weight of original material and refluxed under constant stirring for 30 minutes.
• After draining off the solvent the process is repeated once again. After final draining the
adhering solvent is distilled off and the last traces removed by steam stripping under
reduced pressure.
• The dried matter is pulverized to fine mesh size using a milling machine.

• B. Solvent Extraction Methods
• Chemical Methods.--Chemical methods use solvents to remove water and lipids from fish. The primary purpose in removing
water and the highly reactive lipids is to produce a stable and organoleptically acceptable product for human consumption.
Numerous chemical methods have been developed in various parts of the world to produce FPC. Among the chemical
methods developed are those of the following ,
• The process of making FPC is relatively straightforward. Solvent extracted FPC (type-A FPC) is produced by
extraction with isopropanol. Ethanol has been successfully used as well.
• The raw material is ground and then extracted with isopropanol at 20–30oC for 50 minutes.
• The supernatant is then collected and extracted two times, first at 75°C for 90 minutes with isopropanol and then
at 75°C for 70 minutes with azeotropic isopropanol.
• This gives a final supernatant fraction which is then dried, milled and screened to separate out bone pieces.
• The final product should be largely colorless and odorless and primarily consist of protein (<1% lipids) with high
biological value.

• Uses of FPC
• Specifications
• Crude Protein – 65%, Crude Fiber -0.20%, Ethanol Extract – 12%, Calcium – 4%,
Moisture – 5%, Dry Matter(DM) – 95%, Total Ash(TA) – 10%, Non Protein
Nitrogen(NPN) – 0.15%, Phosphorus(P) – 1.50%.
• Physical Properties
• Yellowish or whitish micron granular powder with/with out odor.
• Shelf Life
• 1 year from the date of Mfg.
• Key Benefits
• Improves growth rate.
• Low cost.

• It is mainly used for
• 1.Eradication of protein deficiency diseases, like Kwashiorkor.
• 2.To incorporated in different preparation like cabbage vegetable
curry, curried fish balls, fish cutlets etc.

• Fish Protein Concentrate or fish flour, is as accepted as human food and not animal
food FPC meets the desired requirements whereas, with the possible exception of
non-fat milk powder, no other dry animal protein in commercial use can since any of
the thousands of fish species under the seas which cover 70% of world’s surface
could be used as a source of protein supplement.

Fish Meal and its uses

• Fish meal, coarsely ground powder made from the cooked flesh of fish.
• Though formerly important as a fertilizer, fish meal is now primarily used in
animal feed—especially for poultry, swine, mink, farm-raised fish, and pets.
• Certain species of oily fish, such as menhaden, anchovy, herring, and
pilchard, are the main source of fish meal and its companion product, fish
oil.

• Fish meal is a dry product having brownish grey colour and milled to a fine to course
powder.
• It is produced by removal of 90 to 95% of water and fat present in the raw material.
• Generally oily pelagic fish is being used all over the world for fish meal manufacture.
• It is a good source of major nutrients such as protein and contains fair amount of fat.
• It is rich in essential minerals, namely phosphorus, calcium and iron.
• It is also a good source of micro minerals, oil soluble vitamins and water soluble
vitamins.

• A major portion (more than 60%) of fish meal produced globally is used for
aquaculture (farming of finfish and shrimp). The intensification of
aquaculture in Asia, and particularly in China, is increasing the demand for
fish meal even though the supply cannot grow accordingly.

• Fish meal, or fishmeal, is a commercial product mostly made from fish that are
not generally used for human consumption; a small portion is made from the
bones and offal left over from processing fish used for human consumption,
while the larger percentage is manufactured from wild-caught, small marine fish;
either unmanaged by-catch or sometimes sustainable fish stocks.
• It is powder or cake obtained by drying the fish or fish trimmings, often after
cooking, and then grinding it. If the fish used is a fatty fish it is first pressed to
extract most of the fish oil.

• Process steps in reducing the fish waste to fish meal
• Heating, which coagulates the protein, ruptures the fat depots and liberates oil and physico-chemically
bound water
• pressing (or occasional centrifugation), which removes a large fraction of the liquids from the mass
• separation of the liquid into oil and water (stickwater). This step may be omitted if the oil content of the
fish is less than 3%
• evaporation of the stickwater into a concentrate (fish solubles)
• drying of the solid material (presscake) plus added solubles, which removes sufficient water from the wet
material to form a stable meal
• grinding the dried material to the desired particle size

• Unit operations in fish meal production
• 1. Receiving of Raw Material
• 2. Cooking In general, cooking is done at a temperature of 95 to 100oC
within 15-20 minutes. Most manufacturers operate cookers to heat the fish
mass rapidly to 95oC. The purpose of cooking is to denature or coagulate
the proteins of fish and to rupture the cell wall of tissues of fish so that it
helps in separating oil and water present in fish.

• 3. Pressing: Pressing operation separates two distinct phases of cooked material.
They are: (1) Solid phase (press cake) and (2) Liquid phase (press liquor).
• Pressing is done using a screw press. The press may be a single screw press or a
double screw press. At present, double screw press is preferred as it removes
maximum quantity of oil and moisture from cooked fish.
• Usually press cake coming out of the screw press contains about 45-55% of water
and 2 to 3% fat. Press liquor coming out of the press is saved for oil extraction.

• 4. Fluffing
• Press cake coming out of the press is in the form of large lumps. In order to
increase the efficiency of drying and to reduce drying time, the large lumps
have to be broken down to small pieces of about 1cm size.
• In the present day fish meal plants, this step is eliminated as press cake is
disintegrated by the screw conveyor which transfers press cake from the
press to dryer.

• 5. Drying
• In the drying process, fluffed press cake containing about 50% moisture is dried to a moisture content of
less than 10%. Two types of driers are commercially used.
• 1. Direct driers or flame driers
• 2. Indirect driers or steam heated driers.
• At present, direct dryers are seldom used by large scale fish meal manufacturers for several reasons.
• It takes about 20 minutes for the press cake to travel from hopper to the exit of the drier. The moisture
content of press cake coming out of the drier should be 10% or less. The dried press cake is then passed
through a magnetic separator to remove any steel contaminants.

• 6. Cooling The fish meal is cooled in coolers. Cooler is equipment which is similar to the drier
except that instead of steam, cold water is passed. In the cooler dried fish meal is cooled to
room temperature.
• 7. Sieving Dried press cake is passed through a vibratory screen specially those who use trawl
bycatch to separate extraneous materials such as wood, cloth, fishing hooks, shells and nails
prior to milling.
• 8. Milling The important objective of milling is to produce fish meal with small particles
averaging around No.40 mesh Tyler screen. The small sized particles thus produced pass through
the sieve fixed at the bottom of the chamber. Normally the exit end of the hammer mill is
connected to a cyclone separator to reduce the problem of dusting.
• 9. Packing, Labelling and Storage Fish meal is usually packed in polyethylene (PE) lined jute bags
or PE lined paper bags or PE lined HDPE woven sacks. The outer packaging is then properly
labeled.

• Importance of Fish Meal
• The nutritive components present in fish meal and their importance in animal, poultry and fish nutrition
is below.
• 1. Depending on the raw material used in its manufacture, its protein content may vary from 40% to 60%.
Hence, fish meal is considered as a concentrated source of protein and it is easy to incorporate with other
feed ingredients so that the desired protein level is maintained.
• 2. Protein present in the meal is a good source of all essential amino acids and hence must be provided in
the diet. As protein of fish meal contains all essential amino acids, its nutritive value is high.
• 3. Fish meal protein is a rich source of amino acid lysine which occurs in deficient quantities in most of the
cereals and legumes.

• 4. Fish meal supplies water soluble B group vitamins such as riboflavin, niacin
pantothenic acid, choline, vitamin B12 in addition to oil soluble vitamins such as vitamin
A and D. As fish is a good source oil, the meal produced from it contains oil to the extent
of 6 to 10%. Oil present in meal contributes towards energy for fish, animals and birds.
This oil helps in growth and fattening of fish, animals and birds.
• 5. Fish meal made from whole fish containing bones is a rich source of essential
minerals such on calcium, phosphorous and magnesium. Calcium is required for bone
formation in animals and birds. Fish meal is also a good source of iron. In addition to
major minerals, fish meal also supplies trace elements such as iodine, molybdenum,
copper, zinc and manganese, all of which are required for various biochemical processes
going on in the body of fish animals and birds.

• 6. Crude fibre content in fish meal is very low. Birds require low content of
fibre in their diet. For proper digestion & absorption of nutrients, the feed
should be low in fibre content, specially for fish and poultry. Hence, fish
meal is particularly suitable for poultry feed.
• 7. Fish meal contains certain growth factors such as protein utilization
factor and animal protein factor which make the feed with fish meal to give
maximum nutritive value as these factors ensure that the dietary proteins
are utilized to a maximum extent in their body.

• Fish meal is a naturally balanced feed ingredient that is high in protein, energy and minerals (e.g. calcium and
phosphorus). In addition, FM is a natural source of vitamins such as choline, biotin and vitamin B12, A, D and E, and
includes various trace elements like selenium and iodine. The compositional quality of the nutrients found in FM
distinguishes it from other dietary supplements, particularly its content of essential amino acids and long chain
polyunsaturated omega-3 fatty acids. Fish meal and fish oil (FO) are the most commonly used feed ingredients that
contain these omega-3 fatty acids. There are two basic types of FM, those that are produced from fishery waste
associated with the processing of various edible human fishery products (salmon, tuna, etc.) and those that are
produced from fish specifically harvested to produce FM (herring, menhaden, pollack, etc.). Fish meal is produced
directly by cooking or drying the raw fish and then extracting the oil. In addition to being a by-product of the processing
of fish for human consumption, FM is also a by-product associated with fish oil production. In some parts of the world,
FM is the primary supplemental protein source provided to livestock because plant derived sources are either
unavailable or too expensive. Five to 10% of FM was used for optimum benefit of young pigs in the diet.
• Most commercial FM is made from small, bony and oily fish that are otherwise not suitable for human consumption. In
addition, some FM is manufactured from the by-products of seafood-processing industries. The balanced amino acid
composition of FM complements and provides synergistic effects with other animal and vegetable proteins in the
animal diet to promote fast growth and reduce feeding costs. High-quality FM and FO provide a balanced amount of all
essential amino acids, phospholipids and fatty acids (DHA; docosahexaenoic acid and EPA; eicosapentaenoic acid)
for optimum development, growth (Gaines et al., 2005) and reproduction (Maldjian et al., 2005). The nutrients in FM
also aid in disease resistance by boosting and helping to increase phytohemagglutinin-induced proliferation and CD4
cell population in spleen cell of laying hens.

Fish Oil,
manufacturing method
and it’s uses

• Definition of fish oil
• a fatty oil from the bodies of various fishes (such as menhaden or
amounts of unsaturated fatty acids and is used as a dietary supplement
products (such as cosmetics and paints).
• Fish oil, previously the main product from raw materials having high oil
secondary value. The product, however, is versatile and finds many
technical industries and is still of considerable economic importance.

• Fish oil is an industrial product of great nutritional value due to its
content of long chain omega-3 polyunsaturated fatty acids (PUFA),
such as docosahexaenoic acid (DHA), docosapentaenoic acid (DPA)
and eicosapentaenoic acid (EPA), which are currently highly valued for
their prophylactic and therapeutic properties in nutritional and health
fields.
• Fish oil, which was previously a by-product of fishmeal used for animal
feed, is now recognized as the primary source of these fatty acids.

• Fish oil can be obtained from different species depending on the
production area. The raw material is comprised of three major
fractions, which include solids, oil and water. The goal is to separate
these components as best as possible, commonly obtaining fishmeal
and fish oil.
• Methods to extract them include cooking, use of solvents and,
recently, extraction by supercritical fluids, by enzymatic procedures
and by chemical (i.e. applying acids) or biological silages.

• Production of Fish Oils
• Raw Material
• According to the Food and Agriculture Organization (FAO) of the UN,
raw material used for the production of fishmeal and fish oil falls into
several categories:
1.Fish caught specifically for reduction to fishmeal and fish oil such as
menhaden, anchovy, capelin and sardines.
2.Incidental or by-catch from another fishery.
3.Fish by-products from the edible fisheries such as cuttings from
filleting operations, fish cannery waste, roe fishery waste and more
recently surimi processing waste.

• The Wet Reduction Process
• The processing techniques involved in commercial production of
edible fats and oils vary according to the type of raw material.
• Fish reduction to produce oil and fishmeal, except for solvent
extraction, generally employs the same principles, techniques and
equipment common to the production of the other edible fats and
oils.

• In general, fish are processed by the wet reduction method in which
the principal operations are cooking, pressing, separation of the oil
and water with recovery of oil, and drying of the residual protein
material.
• Continuous processing from the time the fish are landed optimizes
efficiency and maximizes product quality.

• There are a number of processes that can be used to convert raw fish and
cuttings into fishmeal and oil.
• These fall into several categories defined as wet rendering, hydrolysis, silage
production (autolysis), dry rendering and solvent extraction.
• The wet rendering process is used in the majority of the factories that produce
fish oil worldwide.
• This process is universal, i.e. factories all over the world both on land and on
ships employ it with slight differences in equipment type, but the major steps of
cooking, pressing, separating, and drying are always present.

Table 3. Processing steps used to produce fish oil from fish and fish cuttings
Cooking Steam cooking ruptures the fat cells, coagulates the protein and releases the oil
Dewatering-
Pre-pressing
The cooked fish mass is screened to separate free liquid from the solids
Pressing Pressing mechanically expresses the free liquid from the solids producing a press liquor (oil and water) and a
press cake (semi-moist meat and bones). Some factories have used tricanters instead of presses to separate
solids, oil and water.
Press liquor separation This is 3-step process; decanters separate fine solids from the liquid fraction, separators split the liquid
fraction into fish oil and water (stickwater), and polishing water washes the crude fish oil before it is pumped
to storage.
Evaporation Stickwater contains about 8% solids which are concentrated in multiple effect or waste heat evaporators to
about 40-50% solids. If the factory uses steam dryers then the waste heat from the dryer can be used to heat
and evaporate the stickwater.
Drying The drying process is generally done in 2 stages. The solids from the decanter separation and the press cake
are mixed and partially dried. The partially dried fishmeal is then mixed with the concentrated stickwater and
the drying is completed to about 10% moisture. Factories use steam and indirect hot air dryers but older
factories still use the old direct fired hot air dryers.
Grinding Grinding reduces the particle size of the fishmeal.
Cooling and stabilization The fishmeal is cooled and antioxidant is added. Generally ethoxyquin is the antioxidant of choice but for
certain markets natural antioxidants based on tocopherols are used.
Packaging
The fishmeal is packaged in 50 kg bags or 1000 kg totes. The fishmeal can also be stored in bulk piles or in
silos.
Optional fish oil
carbon treatment
If the crude fish oil is destined for the Omega-3, animal feed, aquaculture or pet food market and if analyses
indicate the presence of dioxins, furans and or polyaromatic hydrocarbons (PAH), it can be treated with
activated carbon to reduce the levels of these compounds.

• Hydrolysis (Enzymatic)
• Hydrolyzed fish proteins are produced by employing proteolytic enzymes
either from the fish themselves (autolysis/silage) or from other sources
(hydrolysis).
• The enzymes can be of either animal, vegetable or microbial source and
accelerate the breakdown of the proteins into smaller units (peptides).
Hydrolysis can also be accomplished chemically under acidic or alkaline
conditions. By using some of the newer enzymes available on the market,
a process can be developed to recover fish peptides of various lengths
with specific functionality. Although the process can be used with any fish,
it is primarily used for white fish or offal low in oil.
• In cases where oily fish are hydrolyzed, the processor must recover the oil
phase without denaturing the proteins or face supplying a high-fat
hydrolyzed protein product or a protein product with reduced functionality.
It has been difficult to achieve a commercially viable product from fatty fish
that is both functional and low in fat.

Figure 3. Hydrolysis process to produce crude fish oil.

• Dry Rendering
• The dry rendering process, which is commonly used to prepare
animal proteins and fats, is not normally used in the manufacture of
fishmeal and oil. However, the process is used with catfish by-
products. In this process the raw material is "cooked" to remove the
water (essentially the drying process in the fishmeal wet rendering
process. The resultant dry cake is then pressed to remove any oil.
Because the water has been removed, the lipid fraction can contain
high levels of phospholipids. The phospholipids normally hydrate in
the wet rendering process and are recovered with the water fraction.
In the dry rendering process, they are not hydrated and therefore
remain dissolved in the lipid or oil fraction. Since there is interest in
the fish phospholipids, it is possible to produce a PL fraction by
hydrating the oil (also called degumming). The dry rendering process
is shown in Figure 5.

Figure 5. Dry rendering process to produce crude fish oil.

Fish Pickle
and its uses

• Fish Pickle
• It’s a side dish that we eat in a moderate quantity. Pickles are known
as taste booster and add flavor to our main meals.
• Fish pickle is simple to make, and you can store it in a glass jar or a
mason jar for at least a couple of months.

Fish sauce

• Fish sauce
• Fish sauce, is a sauce made from fermenting seafood in salt.
• Generally it’s made from anchovies, but it’s also made from tiny
shrimp, tuna belly, and more.
• It can make fish sauce from any seafood.
• It can even make fish sauce at home by packing 3 parts fresh
anchovies to 1 part salt in a large jar and leaving it for a year or so.

• Fish sauce is common in Southeast Asian dishes, but it also has origins in Ancient
Europe.
• The first recorded fish sauce was produced by the Greeks as early as the 7th century
BCE, and it quickly became a Roman pantry staple called garum, which was often made
of fish heads, blood, and guts (yum!).
• It was so popular that trade routes were set up for it.
• Some historians think fish sauce arrived in Asia from the West via the Silk Road, while
others believe it originated separately in Vietnam as a derivative of Chinese soy sauce.
• Whatever the case, fish sauce today is most commonly associated with Southeast Asian
cuisine.
• It's also a key ingredient, the Vietnamese dipping sauce made with sugar, lime juice, and
sometimes chiles that's often served alongside spring rolls and rice noodles.

• What Is Fish Sauce?
• Good fish sauces are made from a mixture of fish and salt that has
been allowed to ferment for up to two years.
• Traditionally, oily fish such as anchovies are placed in a barrel with
salt and slowly pressed to extract the liquid.
• Anchovies are often used, although some fish sauces are also
made from shrimp, krill, or mackerel.
• The basic ingredients of a good fish sauce are fish, water, and salt.

• The fish sauce is made from various types of fish, from both freshwater and
marine fish species by various methods.
• Each has its unique taste and characteristic.
• Fermentation is one of the oldest techniques in food preservation as it not
only extends the shelf-life but also enhances the flavour and nutritional
quality of the product.
• Fish sauce is a translucent amber liquid with a unique aroma and flavour
and is rich in amino acids”.
• It is basically a protein hydrolysate that results from a natural fermentation
of fish and salt.
• Degradation of fish protein to free amino acids is primarily responsible for
the delicious taste of fish sauce.
• It is a rich source of essential amino acids especially lysine and vitamin B12

• The main ingredients are fish extracts and salt along with a few spices.
• It can be made out of fresh, dried, salt-cured or cooked fish.
• Anchovies is the most common choice for fish sauce.
• For the fermentation process, fish and salt are kept in a wooden box and then pressed to
take out the liquid.
• This process alters in different parts of the world.

Fish Soup

perforations are discharged through the end of the refiner as reject.
• The moisture content of refined mince is about 90%. In order to reduce moisture content to about 80-84%,
final dewatering is carried out in a Screw press consisting of a rotary screw and cylindrical screen.
• Sucrose and sorbitol are mixed to dewatered fish meat, serve as the primary cryoprotectant in the
manufacture of the paste and other ingredients are mixed.
• Blended material is shaped into blocks of appropriate size and weight (say 10 kg.). Packed into polythene
