Abstract
The dried foods as rice, corn, wheat, broad bean, lentil, chick-peas, lupine peanut, sesame, dry dlates, spices.....etc. Considered as of nutritional importance to man most of these
foods are imported to Egypt by foreign currency.
Dried foods, in Egypt, suffering from different problems
related to insect infestation and their residual toxins. The
traditional method to resist such insect infestation is the process, fumigation by chemical insecticides. Although the low costs of
these chemical insecticides and the ease of fumigation
the hazardous effect on the human health in of great concern to the consumer. In addition, the fumigation by chemical
insecticides effect the superficial incident only and do not penetrate to the deep insect eggs, which lately hatched and
causing insect invasion even under good packing conditions.
The necessity to a new technology to avoid the hazardous effects of toxic chemical and extend the storagability of the dried
foods, in the same time, became of great importance.
Gamma irradiation technology to control insect
infestation of grains is a recent technology. It appears since four adopted by three international organizations namely decades and
”F AO” (Food and Agriculture Organization), ”WHO” (World Health and ”IAEA” (International Atomic Energy ealth O
of ains was
Agency). The application of irradiation technology gr
cleared and accepted by about 50 countries.
The main object of this investigation is to reduce
qualitative and quantitative losses in grains by using irradiation technology, on the local scale, to avoid all hazards in health, ecology and economy upon using chemical insecticides. The economic feasibility of establishing gamma irradiation
facility for grains in its proposed site in ”El-Obour” market for gross marketing in Egypt.
The present study was classified into four sections:
The first cha ter: contains the loss in grains during the
storage period and their causes of physical and biological contamination. Also the adopted methods to control these losses in grains market in Egypt. The obtained data have revealed the dangerous continuity of the present status of the Egyptian markets under chemical insecticides fumigation processes.
requireThe second cha ter: contains the technical facilities insect required for establishing of drie ”gamma irradiation project” devoted for
disinfestation d foods and all international and experience in radiation disinfestation of dried foods andlocal the optimal dose for each food item.
The third cha ter: Particularly for marketing study which divided into two pa
parts:
Part 1: contains the periodicalarrangement f
the ”full capacity” of the irradiator along the year by or knexploitingowledge the harvest time of each crop, capacity of the irradiator (dose rate), the amount of each crop per ton [the proposed amount of grains equals 15000 tons per month,
from cobalt 60 equals 513115 Curies]the activity radiation source
Part 2: contains public investigation about the consumer acceptance for the irradiated food. To achieve this part a completely randomized sample involved 150 consumers in ”Cairo” city was taken the declaration cheat involved different questions declaring the consumer ability to buy and consume irradiated grains and the effect of different parameters as age, educational status, sex and location.
The fourth cha ter which considers the backbone of this investigation and focused upon the financial analysis of establishing of a food irradiation processing unit taking the main objective of evaluation of benefits on the private investor commercial scale. The financial analysis was done according to cash flow system of the International Bank for development taking into account that the project will be carried out as a
private sector. The financial analysis contained the initial investment costs of 22.88 millions Egyptian pound (LE) and annual labour costs of 0.6 millions LE, annual operation expenditures by 1.72 millions LE, pre-operation — costs by 0.650 millions LE, annual depreciation provision by 0.86 millions LE. The annual radiation processing costs including profitability, annual processing costs and annual depreciation provision was evaluated by 6.01 millions LE annually.
The determination of irradiation costs per hour and per ton during different capacities of 100, 90 and 80% was also taken into consideration this irradiation costs was also dependant upon the irradiation dose which 0.5 KGy for grains and 1.0 k.Gy for dry dates and 10.0 k.Gy for spices.
The commercial profitability of the project was determined according to cash flow tables, Internal rate of return (I.R.R) and Pay back period (P.B.P).
The sensitivity of the project was also analyzed under the conditions of revenue decrease and expenditures increase.
The study have also revealed that the commercial profitability of the project was acceptable for both evaluation systems of Internal Rate of Return (IRR=17%) and Pay Back period (P.B.P= 5.9 years).
Contained the added value to the national income upon the establishment of irradiation facility of dried foods.
In this section, attention was focused chiefly upon wholesomeness of the community and ecology, improvement of marketing ability and keeping quality of foods and the added value to our national income. The added value to the national income was 43.064 millions LE annually which reflects positive health, ecologic, marketing and financial returns.
