The farmers produce suffer great losses when they are sealed in plastic or gunny bags. When the produce is done in bulk, the farmers and traders preserve the stock and try their best to maintain the commodity in perfect condition.
Since traditional preservation methods are inadequate, storage techniques cannot prevent wastage due to pests and diseases. Panama Foundation has innovated a grain bag also known as a hermetic bag. It is an air-tight bag that helps in preserving the produce for a long time and the aroma of the grains remains intact
The hermetic bag needs to be inserted inside a standard storage bag and then the grains are poured in it. The bag should be tied tightly with the cable wire provided along with it so that the air does not come into contact with the dry pulses stored inside. The polymer used in these bags is approved by Food and Drug Administration (FDA).
Hermetic storage of oilseed and grains is one of the best solutions for reducing food losses in developing countries. In order to obtain the full benefit of the hermetic storage, it is required to achieve a low O2 concentration or high CO2 concentration.
The gas concentration inside a hermetic bag is the result of the balance between respiration and gas exchange rates with the outside (permeability and leakage). If the grain is dry, there is an insufficient modification in the internal atmosphere which allows insect development and leads to grain losses.
The use of liners with a gas barrier is an alternate to improve the effect of hermetic storage systems since the O2 entrance and CO2 losses are sharply reduced. This creates an internal atmosphere with a higher modification level than standard liners, with potential conservation benefits. Liners along with gas barriers are very costly and it may not be affordable for family storage systems.
Dry pulses with coffee and tea beans can be stored in hermetic bags in dry places. Vegetables and Fruits create a contrasting effect and should not be stored in these bags. If no gas leak is there from any opening, the pulses will be fresh over the year without any germination.
