FSSAI (Food Safety and Standards Authority of India) registration is a mandatory process for all food businesses in India to ensure food safety and quality. It involves obtaining a unique 14-digit registration or license number, which must be displayed on food packages. The registration process varies based on the size and nature of the business, categorized into Basic Registration, State License, and Central License. FSSAI registration helps maintain standards, prevents food adulteration, and promotes public health. It enhances consumer trust and enables businesses to comply with legal requirements, facilitating smoother operations and market access.
