The Food Safety and Standards Authority of India (FSSAI) regulates the food industry in India. Under the FSSAI Act of 2006, all food businesses must obtain a license depending on their annual turnover - a basic registration for under 12 lacs, a state license for 12 lacs to 20 crores, or a central license for over 20 crores. The licensing process involves submitting documents verifying identity and business details, undergoing inspections to ensure food quality standards are met. Obtaining an FSSAI license is mandatory and helps maintain oversight of the food industry.
