Postharvest Loss Reduction of Fruits in Bangladesh: Achievements and ChallengesSamar Biswas
A study was done to find the present status, causes of losses and remedies of postharvest loss of fruits in Bangladesh. Farmers are producing huge number of fruits but poor postharvest handling and practices caused about 25-50% losses of fruits in our country. The total loss due to poor postharvest processing of fruits in Bangladesh when valued in monetary terms reflects a tremendous loss in the economy. The gross value of the losses stands at Tk. 6.120 to 8.160 million. Such a situation doesn't only reduce the national income but also leads to malnutrition and socio-economic problems. Main causes of postharvest losses are improper harvesting, packing, excessive and rough handling, poor transportation and storage facilities. Both the government and private sector need to invest much effort in research and extension towards improving and modernizing postharvest facilities for attaining more efficient market infrastructure and distribution channels. Research and extension activities have to be closely coordinated particularly in the public sector for the benefit of farmers, traders and consumers.
Cleaning refers to chlorine washing of the banana fruit for the removal of undesirable material including latex, chemicals, adhering soil particles along with the microorganisms carried by the soil.
Sorting in banana would refer to removal of overripe, injured, bruised, rotten, diseased, infected and cut fruits.

The presentation will focus on the application of the FoodPro® Cleanline enzyme Glycerophospholipid Cholesterol Acyltransferase (GCAT) in the milk, which converts cholesterol to cholesterol esters and lysophospholipids. Lysophospholipids are surface-active amphiphiles that will act as biosurfactants and prevent protein aggregation and promote refolding of proteins (chaperone-like properties), resulting in various processing advantages and increased emulsion stability when used in the manufacture of milk and dairy products. GCAT can reduce free cholesterol in milk by as much as 65 to 85%, which could potentially be an important advantage from a nutritional point of view when producing milk and dairy products.

Ripening.ppt ruit ripening is a natural process in which a fruit goes through...RoselynAdajar
Ripening is a process in fruits that causes them to become more palatable. In general, fruit becomes sweeter, less green, and softer as it ripens. Even though the acidity of fruit increases as it ripens, the higher acidity level does not make the fruit seem tarter. This effect is attributed to the Brix-Acid Ratio.
Fruit ripening is a natural process in which a fruit goes through various physical and chemical changes and gradually becomes sweet, colored, soft, and palatable. Fruit ripening process can also be stimulated by applying artificial fruit ripening agents. Farmers and vendors often use artificial ripening agents to control the rate of fruit ripening. However, because of the potential health hazards related to the ripening agents, artificial fruit ripening process is highly debatable throughout the world.Different fruit ripening agents can be used to ripen fruits artificially and to provide fruits the desired color and taste within a short time. In recent years, the use of artificial fruit ripening agents is becoming much prevalent, the agents being mostly used for commercial purposes, i.e., to make the fruits available to customers during off-season.
atural fruit ripening is a combination of physiological, biochemical, and molecular processes [21–24]. It involves coordination of different metabolisms with activation and deactivation of various genes, which leads to changes in color, sugar content, acidity, texture, and aroma volatiles [21, 22, 25]. The change in color during the fruit ripening process is a result of unmasking of pigments by degradation of chlorophyll, synthesis of different types of anthocyanins and their accumulation in vacuoles, and accumulation of carotenoids. Production of complex mixture of volatile compounds, such as ocimene and myrcene, and degradation of bitter principles (diverse groups of plant constituents such as alkaloid and sesquiterpene are linked only by their bitter taste), flavonoids, tannins, and other related compounds enhance the flavor and aroma of the fruit. Sweetness increases because of increased gluconeogenesis (metabolic pathway that generates glucose), hydrolysis of polysaccharides, decreased acidity, and accumulation of sugars and organic acids. Furthermore, textural changes resulting in the softening of fruits occur due to enzyme-mitigated alteration in structure and composition of the cell wall [23, 26, 27]. Through the above changes, fruit becomes ripe with distinctive characteristics: sweet, colored, soft, and palatable.
Artificial fruit ripening and possible health hazards
Ethylene, a hormone naturally produced within fruit, regulates fruit ripening by initiating and/or controlling a series of chemical and biochemical activities [28]; the compound does so by coordinating the genes responsible for activities including increase in the rate of respiration, autocatalytic ethylene production, chlorophyll degradation, carotenoid synthesis alongside conversion of starch to sugar, increased a

7. NON-CLIMACTERIC FRUITS : Once harvested, these fruits
do not ripen further.
In order to attain full ripeness and flavor, these fruits
are often harvested once they have fully ripened.
Thus have a short shelf life if harvested when they are
ripe
CLIMACTERIC FRUITS : They enter climacteric phase
after harvest, that is they continue to ripen although off
tree.
Most ripened climacteric fruits are too soft and delicate
to withstand transportation & handling.
The ripening process is considered irreversible in
climacteric fruits

Deficiency:
skin color, freshness may
be affected and may cause
splitting, weak necks,
breaking, weight loss and
may cause existing
blemishes to become
enhanced.
Begin ripening:
90% RH (use automatic
humidifiers with humistats
control)
Color break:
Reduce RH to 75%
4. AIR
CIRCULATION
Assures uniformity of ripening
and prevents buildup of CO2.
Air circulation fans operate
continuously while ripening

Fruit boxes are stacked to
allow air circulation.
Many stacking patterns are
available, but a 4-inch air
channel is ideal.
Rule of thumb
The discharge from the AHU
blower in cubic feet per minute
should equal the cubic capacity
of the ripening room.

17. Normally, Iodine (I) can be used to determine whether the fruit is
ripening or rotting by showing whether starch in the fruit has turned
into sugar. For example, a drop of iodine on a slightly rotten part
(not skin) of a banana will turn a dark-blue or black color, since
starch is present. If it stays yellow, then most of the starch had
converted to sugar.
• Other simple Method is given color indicator chart at various
sources. One Shown herewith.
