|Processing of cassava into dried chips|
116. If a product is not properly dried and still contains moisture, it can easily be spoiled by moulds and insects.
117. Well dried cassava chips can be stored for 6 to 12 months.
How should you store the chips?
118. If you want to keep the chips for a long time, you must not store them in open containers.
119. You must store them in closed containers. Otherwise they will be attacked by insects.
120. Insect attack can be a big problem in the long- term storage of dried chips.
121. If bags are used, they must be lined with polyethelene sheets and be tightly closed. Then insects cannot get in.
122. Bags and gunny sacks must be stored on wooden pallets. This will increase the flow of air and also prevent direct contact with the floor.
123. You can use containers made of wood or metal to store the cassava chips. Containers can be made effective by lining them with polyethelene sheets.
124. If it has rained during the drying process or if it took a long time to dry the chips, there is a strong chance that mould will grow and insects attack. You can protect the chips from this by sprinkling them with a salt solution while drying and then storing them carefully.
125. There is another way by which the storage life of the chips can be increased. Immerse the fresh chips in boiling water for ten minutes and then dry them in the usual way. These chips will have a long storage life.
126. Freshly harvested cereals carry insects inside the grain, whereas freshly dried cassava chips have no insects within them.
The insects will come from the storage environment.
127. The storage area must be kept clean and well ventilated. In a good storage environment, you can keep insects out and store the dried chips for a long time.
