Any food that does not meet minimum standards is considered adulterated. Food adulteration involves adding non-nutritious substances intentionally in small quantities to improve appearance, flavor, texture or storage. It is done to increase profits, weight or trade volume. The Prevention of Food Adulteration Act defines adulterated food as containing poisonous, deleterious or added substances that can render the food injurious to health. Several agencies regulate food safety and quality in India through various acts.
