Description: Fruits and vegetables are generally perishable goods. Without
proper preservation, they are often spoiled due to microbial degradation
or enzymatic reaction. Preservation
techniques aim at complete or partial destruction or elimination of
microbial agents (mold, yeast, bacteria’s) or by inhibiting their growth
and activity. Through preservation,
it is possible to store, transport and distribute fruits and vegetables
without changing their basic natural content.
- Rationale: In
recent years, a culture of growing and producing fruits and vegetables for
commercial purpose has been developing in the Amhara Region, especially in
communities close to urban centers.
Unfortunately, in some season of the year, a lot of fruits and
vegetables is harvested which the market can not absorb. As a result, farmers are forced to sell their
produce at very low prices, and this discourages farmers from producing these
crops. In other seasons, the very
crops which were in large supply one or two months before are not
available in the market. One main
cause of this fluctuation in the supply of fruits and vegetable is the
lack of preservation system for these produces. Through the problem of perishability of
fruits and vegetable can not be eliminated completely, using different
methods of preservation will help both the producers (farmers) and the
consumers. Hence, the need of
promoting such type of a plant is obvious.
Potential: Except some traditional and crude methods of preservation,
the whole Amhara Region does not have any single plant which is engaged in
the preservation of fruits and vegetables through drying, canning and
other techniques of preservation.
The volume of fruits and vegetables that are sold at “throw- away
prices” and are left to rot in some localities in the Region could justify
the establishment of a plant which will be engaged in the preservation of
fruits and vegetables.
- Source of Raw
Material: Production of fruits
and vegetables is more prominent in areas around Bahir Dar, along Bahir
Dar-Woreta road, around Gondar,
near Dessie and Combolcha.
Process & Technology: There
are several methods of preserving fruits and vegetables from
spoilage. These include heat
treatment, dehydration, salting, pickling, preserving with sugar and
chemical freezing and sterilization by electric or ultraviolet. This project idea deals with the drying
and canning forms of preservation.
The process of preserving fruits and vegetables through drying
involves cleaning and washing, peeling, drying and packing. There are different equipments used for
the drying of fruits and vegetables depending upon the type of the
product. The most common ones are
cabinet dryer, tray dryer, horizontal dryer.
is a preserving method in which food products are kept in a hermetically sealed
container and given a heat treatment to kill all the micro organisms, so as to
increase the shelf-life of the product.
Canning of food consists of the following steps. Preparation of fruits and vegetables for
canning includes washing, peeling, coring and trimming, slicing and blanching. Canning includes can filling, exhausting,
sealing, processing and cooling. Plant
and machinery include peeling, slicing, pricking machines, tanks, boiler, weigh
scale and other accessories.
