Adulteration is defined as the process by which the quality or the nature of a given substance is reduced through the addition of a foreign or an inferior substance and the removal of a vital element.
TYPES OF ADULTERANTS
Intentional adulterants are those substances that are added as a deliberate act on the part of the adulterer with the intention to increase the margin of profit. Eg. sand, marble chips, stones, mud, chalk powder, water, dyes, etc., These adulterants cause harmful effects on the body.
These adulterants are found in food substances due to ignorance, negligence or lack of proper facilities. It is not a willful act on the part of the adulterer. Eg. pesticides, droppings of rodents, larvae in food.
PACKAGING MATERIALS AND HAZARDS
Materials used for packing
The conventional methods of packing which are prevalent even now to a large extent are tin or aluminium containers, glass bottles and jars, paper and waxed paper wrappings, paper cartons, cardboard and certain plastic containers. Tin and aluminium containers have become costly and glass bottles though very good in many respects have problems associated with breakage and heavy transportation charges on account of weight. Continued use of paper in increased volume dwindles the natural resources.
