What is food adulteration?
Food adulteration is a process in which the quality of food is lowered or reduced by replacing food ingredients adding non-authenticated substances or removal of a vital component from food to earn profit or due to other incidental reasons.
Adulterants are often added to food products for economic gain. They may be cheaper, readily available substances that mimic the color, texture, or taste of the original ingredients. For instance, chalk powder is commonly used as an adulterant in spices, while water is often added to milk.
Unintentional adulteration, on the other hand, occurs due to the careless handling or improper storage of food products, leading to contamination by harmful substances.
The consumption of adulterated food can lead to various health problems, ranging from stomach disorders to more severe conditions like cancer, kidney dysfunction, and heart diseases. For instance, the consumption of food adulterated with non-permitted colors can lead to allergic reactions and hyperactivity in children.
In many countries, food adulteration is considered a punishable offense. In India, for example, the Food Safety and Standards Act regulates the sale of adulterated food. Consumers also have the right to report cases of food adulteration to the relevant authorities.
Despite various actions and penalties, the practice of adding adulterants is quite common in developing countries. There are various methods used for adulterating natural products. Various methods of food adulteration are deployed by the food industries using various chemical and synthetic substances.
