Fruit Juice, Jams, Jelly & Sauces
Fruit juices, jams, and jellies are widely consumed food products that provide essential nutrients and contribute to a balanced diet. However, due to their sweet nature and preservation methods, they are vulnerable to adulteration, contamination, and quality degradation. The Food Safety and Standards Authority of India (FSSAI) has laid down specific guidelines for the analysis of fruit juices, jams, and jellies to ensure their safety, nutritional value, and compliance with food standards. These standards help in maintaining product integrity, consumer health, and regulatory compliance.
