Storage losses can be classified in two categories: direct losses, due to physical loss of commodities; and indirect losses, due to loss in quality and nutrition. It is important to consider both damage and losses by the insects during storage instead of just weight loss.
In respect to this, how are the stored grain damage?
These larval tunnels, along with the feeding damage of adults and larvae, inflict the most damage on grain in storage, but other types of damage are also caused by insects, including: Insect feeding directly reduces grain weight; … Maize spoilage in storage from infestation and feeding by insects in Zambia.
Moreover, what are the 3 types of food storage?
There are three types of food storage options: dry storage refers to the storing of items which don’t require a climate controlled environment; refrigerated storage is defined as foods that require storage at a cool temperature, but not a freezing temperature; and frozen food storage, which are foods that are required …
What are the different factors which affect losses of store grain write in detail?
Four factors which greatly affect grain storability are grain moisture content, grain temperature, initial condition of the grain and insects and molds [10]. These factors are also all interrelated.
What are the factors affecting the storage?
Factors that affect food storage:
- Temperature: The temperature at which food is stored is very critical to shelf life. …
- Moisture: It is recommended to remove moisture when storing foods. …
- Oxygen: Foods store best when oxygen free. …
- Light: Light, a form of energy that can degrade the food value of foods.
What can destroy wheat?
Armyworms are among the most common and damaging insects to wheat. While they don’t infect the plant like aphids can, they do feed on a significant amount of wheat during their life times.
What causes grain losses?
Insufficient drying of grain can cause losses from the development of moulds and insects. Threshing can cause losses from broken grains and encourage the development of insects. Poor storage conditions can bring about losses caused by the combined action of moulds, insects, rodents and other pests.
What is the grain storage of India?
The current food grain storage capacity in the country is 877.37 lakh tonnes (covered – 749.90 lakh tonnes and Covered Area Plinth (CAP) – 127.47 lakh tonnes) with FCI and State agencies as on 31 October 2018.
What is the purpose of storage of grains?
For small farmers the main purpose in storing grains is to ensure household food supplies. Farm storage also provides a form of saving, to cover future cash need through sale, or for barter exchange or gift-giving.
What is the storage of food grains?
Food grains are stored in large quantities in granaries. Thousands of gunny bags containing grains are stored in the granaries which are considered as big rooms with ventilation. Grains are also stored in the Silos to protect them from pests and other factors.
Why does storage of grains cause losses?
Physical loss of grain in storage is the result of pest infestation (Insects, birds and rodents), microbial infection, change in moisture content, poor handling and grain respiration and microorganic/microbial consumption.
Why storage is important for food grains?
The food grains obtained by harvesting the crops are dried in the sunshine before storing to reduce their moisture content.It is necessary to prevent them from spoilage. The higher moisture content in food grains promotes the growth of fungus and moulds on the stored grains which damages them.
Why storage of grains is important?
It is important to store grains because of the following reasons: High temperature and high moisture affect grain quality and can cause rapid decline in germination, colour, oil composition, and many other characteristics of grains. … High temperature and moisture favour development of insects and moulds.
