6. More About
Ice Cream
Ice Cream is a combination of air,
ice crystals, fat globules, and a liquid
syrup.
These are combined to make a
colloid, a solution with very small
insoluble particles suspended in it.

15. Fats Important for creaminess of ice cream
Proteins
from milk
Form a membrane around the fat droplets, making it
harder for them to come in contact with each other
Emulsifiers Replace some milk protein on surface of fat droplet
Stabilizers Reduce the rate at which ice cream melts, add
smoothness and increase viscosity of the liquid phase
of ice cream 15

16. Ingredients - Fats
As ice cream is made, some of the fat in the droplet
solidifies, and the fat needles that form help droplets to
partially cluster. These clusters, along with milk
proteins, help stabilize air bubbles in the ice cream.

17. Ingredients – Milk Solids-Not-Fat & Sugar
Milk SNF
Solids-not-fat have high nutritional
value and ability to improve the
texture of ice cream by binding and
replacing water.
They significantly effect the correct
distribution of air during freezing of
ice cream.
They consist of protein, lactose, mineral
salt & added in form of powder and
condensed skim milk.
Sugar
10-15% sugar is added
to adjust the solid
content and gives sweet
taste which is preferable
to consumers.
Cane & beet sugar,
glucose, fructose &
invert sugar or their
mixture are used.
17

18. Ingredients – Stabilizers
Stabilizers Functions
Proteins --
Gelatin,
Casein,
Albumin,
Globulin.
CHOs --
Hemicellulose,
Modified
Cellulose
Aid in producing a smooth body texture.
Maintaining characteristics during storage.
Reduce the amount of water in the mix.
Increase the viscosity of the mix.
Help in suspension of flavouring particles.
Reduce the growth of lactose crystals during storage.
Prevent shrinkage of the product volume.
Use of multiple stabilizers can produce synergistic effects.
They are extracted from plants, brown seaweeds. 18

19. Ingredients – Emulsifiers
Emulsifiers Functions
A mixture of
monoglycerides & di-
glycerides.
Mono, di-glycerides
(E471)
Lactic acid ester (E472)
Propylene glycol ester
(E477)
Promotes dispersion & aid in keeping the
ingredients of ice cream mix finely divided.
They orient themselves at the fat water
interface in mix, thus reducing the internal
tension and retarding the clumping of fat
globule.
They provide supplementary action which
produces a drier appearance.
Improved air cell distribution.
Improved heat shock resistance.

20. Ingredients – Flavoring & Coloring Matters
Coloring Matter
Artificial color matter mixed
to give an attractive
appearance to ice cream.
To enhance the color of fruit
flavoring additives.

Flavoring Matter
DRY NATURAL LIQUEUR
Chocolate Citrus fruit Alcohol

22. Structure Of
Ice Cream
Small ice crystals are required for smooth ice cream.
During freezing, most water is frozen into ice.
Beating and aeration occur at the same time as freezing to
form small air bubbles, stabilized by de-emulsified fat.
Air makes us 30-50% of ice cream’s final volume.
Sugar sweetens the ice cream, and lowers the freezing point
of water, reducing the amount of ice.
Soft ice cream contains less ice. 22

29. Packaging of ice cream
The most common machines for the packaging of Ice Creams are:
SRS ATP line with high speed artificial vision guided robots
Flowpack packaging machines

30. Ice cream is good practice to store edible ices in factory cold
stores at typically - 25°C.
Ice cream should be kept cold with minimal temperature
fluctuations throughout the cold chain, from factory cold store
to retailer's cold store to store freezer, to prevent a decrease in
product quality due to ice recrystallization and coarsening which
gives the ice cream a grainy texture.
Cool boxes or bags are a great help to keep the products cold.
A core temperature lower than - 18°C is regarded as the good
practice reference for consumer units.
STORAGE
30

31. Do not allow ice cream to repeatedly soften and re-freeze.
Your freezer should be set at between -5°F and 0°F. Ice cream is
easy to dip between 6°F and 10°F, the ideal serving temp. range.
Store ice cream in the main part of the freezer.
Keep the ice cream container lid tightly closed when storing in the
freezer to reduce the formation of ice crystals.
For long periods of storage, putting the ice cream in a gallon freezer
bag will also help minimize ice crystals.
Don't store ice cream alongside uncovered foods; odors may
penetrate ice cream and affect its flavor
STORAGE - At Home
31

32. The optimum temperature is 0°F (-18°C) or colder.
The temperature in the supermarket's freezer case should not be
above 10°F (-12°C) to prevent thoroughly freezing of Ice cream .
If the product is soft, you may wish to bring it to the attention of the
store manager.
Put ice cream products in the separate section of your grocery cart,
or place on top of other groceries.
Insulate ice cream products for the ride home with a freezer bag or
additional brown paper bag.
Make the grocery store or ice cream parlor your last errand before
going home.
STORAGE - In the Store
32

33. TRANSPORTATION
COLD CHAIN
Steps in cold chain for transporting
ice cream might include:
Supply: The ice cream is made and
packaged in a plant.
Transport: Ice cream is generally
transported in a refrigerated truck &
they undergo routine inspections to
ensure they are in tip-top condition.
Storage: Ice cream might go into cold
storage before it is distributed.
Warehouses can sell food to grocers.
Product might enter the cold chain again
for distribution after purchasing. 33
Market: In most cases, the final step in
the cold chain is delivery to the
grocery store where consumers
purchase ice cream.
The cold chain might continue at SM.
Here the ice cream might be stored in a
walk-in freezer for a little while
before it makes its way into the
frozen display to purchase.

Nutraceutical substances that
are not degraded under frozen
temperature can be introduced
with ice cream. As ice cream is the most
popular products in all over the world, so this
type of fortification can be a good way to
make ice cream more beneficial and reduction
of disease status in people.

49. Types of Frozen Products On the Basis Of OVERRUN

50. OVER RUN OF ICE-CREAM
Amount of air added to the ice cream is
called over run.
Incorporation of air into ice cream
incorporated into the mix depends on the
composition of the mix.
Increased volume is composed mainly
of air incorporated during the freezing
process.

51. OVER RUN OF ICE-CREAM
The factors that
depress overrun
 Fat content
 MSNF content
 Amount of mix in batch
freezer
 Poor homogenization
 Insufficient refrigeration
Factor listed as
enhancing overrun
 Sodium caseinate
 Whey solids
 Emulsifiers
 Pasteurization of mix
at higher temperature

52. OVER RUN OF ICE-CREAM
Overrun calculations
It is the % increase in volume of ice cream greater than
theamount of mix used to produce that ice cream
% Overrun =
𝑽𝒐𝒍.𝒐𝒇 𝒊𝒄𝒆 𝒄𝒓𝒆𝒂𝒎 − 𝑽𝒐𝒍.𝒐𝒇 𝒎𝒊𝒙 𝒖𝒔𝒆𝒅
𝑽𝒐𝒍.𝒐𝒇 𝒎𝒊𝒙 𝒖𝒔𝒆𝒅

𝐖𝐭.𝐨𝐟 𝐬𝐚𝐦𝐞 𝐯𝐨𝐥.𝐨𝐟 𝐢𝐜𝐞 𝐜𝐫𝐞𝐚𝐦
× 100

53. RESULT OF OVERRUN
According to BSTI ( BDS 1083: 2006 ) Overrun
1 Liter Ice cream = 525-540gm of ingredients ( Milk) 92%-95%
When 1 Liter Ice cream weight is 400gm 120%
Advantages
of Overrun
Enhance the texture with light, creamy, less cold.
Enhance the palatability factors like chewing
properties, taste.
Without overrun ice cream become frozen block / ice
cube.
Become possible to scoop and eat with good taste.
