Which two factors bring loss of food grains during storage?
Answer: The following factors are responsible for loss of grains during storage: (i) Abiotic factors like humidity and temperature. (ii) Biotic factors like insects, rodents, birds, mites and bacteria.
What factors may be responsible for loss of grains during storage suggest two preventive and control measures?
(i) Biotic factors : These include rodents, fungi,insects, mites and bacteria. (ii) Abiotic factors: These are like inappropriate moisture and temperature conditions in the place of storage. (b) Preventive measures: (i) Strict cleaning of the produce before storage.
What are the factors responsible for 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 types of losses are possible in storage?
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.
What are the affecting factors why we process and preserve food?
Several intrinsic and extrinsic factors associated with foods serve to promote preservation, the most important of which include: water activity (aw), temperature (low or high), preservatives (i.e., nitrite), acidity (pH), competitive microorganisms (i.e., lactic acid bacteria), and redox potential (Eh).
What are the biotic and abiotic factors that affect storage of grains?
Answer: Storage grain losses occur due to biotic and abiotic factors. The biotic factors are bacteria, fungi, mites, insects and rodents. The abiotic factors are moisture and temperature.
How do storage grain losses occur explain any two factor?
Four factors which greatly affect grain storability are (1) grain moisture content; (2) grain temperature; (3) initial condition of the grain; and (4) insects and molds. These factors are all interrelated.
What is food grain storage?
Covered storage: This is the most popular storage method used by FCI, CWC and SWCs. It is the method wherein a jute bag is used to store the grains. Grains packed in jute bags are piled inside warehouses or godowns. Silo bag technique: Silo-bags is hermetic-type storage made with a plastic bag in the shape of a tube.
What are the major causes of postharvest losses?
Causes of post-harvest loss in this stage include limited availability of suitable varieties for processing, lack of appropriate processing technologies, inadequate commercialization of new technologies and lack of basic infrastructure, inadequate facilities and infrastructure, and insufficient promotion of processed …
Which is responsible for loss of grains during storage?
Answer Both biotic and abiotic factors are responsible for the loss of stored grains. Abiotic factors include improper temperature of store house, humidity ofair and high moisture content of the grains. Improper containers used for storage also cause loss of grains.
Why is it important to prevent grain spoilage?
Preventing loss of grain quality from mites and moulds during storage grains, cereals, oilseed, and pulse crops is easier, safer and less expensive than any remedial or curative programme to improve spoiled grain. The goal of effective grain storage is to avoid quality losses from the time the grain is stored until the time it is used.
Why is moisture an important factor in grain storage?
Moisture also plays an important role in the safety of the stored grains. Moist and warm conditions are the favorable conditions for insects, pests, and fungus to flourish. The presence of moisture also causes discoloration of grains and reduces its quality.
What are the major hazards in grain storage?
The major hazards in grain can only be controlled by strict application of Good Storage Practices and Hazard Analysis and Critical Control Point (HACCP) plans. The GT Programme paves the way for implementing efficient GSP systems as well as the new regulatory requirements.
