Food Grains, Pulses & Cereals
Food grains, pulses, and cereals are staple food items that provide essential nutrients like carbohydrates, proteins, vitamins, and minerals. These foods form the foundation of the diet for a large part of the global population, and their quality, safety, and nutritional value are of utmost importance. The Food Safety and Standards Authority of India (FSSAI) provides comprehensive guidelines for the analysis of food grains, pulses, and cereals to ensure that these food products are safe, free from contaminants, and nutritious. Through rigorous testing of physicochemical, microbiological, and sensory parameters, FSSAI ensures the quality control of these essential food items.
