Fruit beverages are made from fruit juices or pulp that undergo minimal processing like filtration and pasteurization before being mixed with ingredients like sugar, acid, and preservatives. Ready-to-serve beverages as specified by FSSA must contain at least 10% fruit content and 10% total soluble solids while having a maximum acidity of 0.3% citric acid. They also allow preservatives up to 70ppm sulfur dioxide and 120ppm benzoic acid since no dilution is needed before drinking. The document outlines specifications for fruit beverages and provides process flow sheets for making mango, orange, and jamun ready-to-serve beverages.
