Question

Name the various factors affecting the storage of agricultural produce

Answer 1

Factors that affect food storage:

Temperature: The temperature at which food is stored is very critical to shelf life. United States Department of Agriculture, USDA, states that for every 10.8 degrees in temperature rise you decrease the shelf life of stored food by half. The best range for food storage is a constant temperature between 40-60 degrees. Avoid freezing temperatures.

Moisture: It is recommended to remove moisture when storing foods. For long term storage foods should have a 10% or less moisture content.

Oxygen: Foods store best when oxygen free. Removing oxygen will prevent oxidation of compounds in foods. Ways to remove oxygen:

Displacing oxygen – Purge air from product with an inert gas (nitrogen). Dry ice is often used giving off carbon dioxide gas which displaces oxygen.

Oxygen absorber – Air contains about 78% nitrogen and 21% oxygen, leaving about 1% for the other gasses. If the oxygen is absorbed, what remains is 99% pure nitrogen in a partial vacuum.

Light: Light, a form of energy that can degrade the food value of foods. Store food in dark areas.

Container: Store foods in food grade plastic, metal or glass containers indicating that the container does not contain chemicals that could be transferred to food and harmful to your health. For best storage life, use containers with a hermetic (air tight) seal. Containers with air tight seals are:

#10 cans

Sealable food storage buckets

Sealable food quality metal (lined) or plastic drums

Foil pouches

PETE bottles (for dry products such as wheat, corn, and beans)

The containers listed above, used with oxygen absorber packets, eliminate food-borne insects and help preserve nutritional quality and taste.

Warning – Botulism poisoning may result if moist products are stored in packaging that reduces oxygen. When stored in airtight containers with oxygen absorbers, products must be dry (about 10% or less moisture content).

Infestation: Several common insects infest home-stored dried foods. To control with cold treatment, put infested items in a deep freeze (0 degrees) for three to four days which will kill any live insects, larva and eggs.

Shelf date is the “best if used by” date meaning that you are getting most of the original taste and nutrition. The “life sustaining shelf life” date means the length of time that food is still edible.

Answer 2

There are various factors affecting teh storage of agricultural products such as temperature, moiture, atmosphere, and container.

Explanation:

Food storage is a traditional practice that ensures food safety and security in the time of need. there are several reasons of storing food such as provides balanced diet in the whole year, ready fro any kidn of emergencies relted to food scarcity, and preserves provessed food for later use.

Following are the various factors affecting storage of agricultural proucts:

1. Temperature:  Temperature is a very important factor affecting food, like the temperature should be low for food storage, at high temperature the food will not lost for long. The temerature should be below 60°F. The temperature should remains constant because frequent changes can reduce the life of food.
2. Moisture : The food sgould be moisture free in the stored containers otherwis eit will get spoil. Grains should have 10% or less moistuer content for long term use.
3. Atmosphere : Foods are stored in the place which should oxygen free because oxygen, oxidizes many important compunds of food. Food can also affect by bacteria and can food rancid.
4. Container: The container for agricultural products should be air-tight or sealed to avid its contact with oxygen. Storage container should be made up of good plastic, glass or metal so that it could not affect the food inside chemically.
