3.2.2.1.Filling of cans
Placing a definite quantity of well prepared food into clean cans can be considered as packing or filling. The amount of solid material packed into the can is referred as solid pack. The quantity of solid packed depends on the size of the can. The liquid media is filled either by measuring or by weighing. It is important that every can has to be packed uniformly with respect to arrangement of fish inside the can. Both overfilling and under filling of cans is not acceptable. Filling the cans beyond the acceptable limits not only cause losses to the manufacturer but also creates several other problems. Under filled cans may be rejected by the consumers and quality inspectors as they are considered defective.
