ABSTRACT:
The invention provides Potassium bitartrate, pectin, L(+) tartaric acid and fruit sugars present in tamarind pulp, which are recovered sequentially by extracting the pulp in water, concentrating and chilling the extract, filtering out potassium bitartrate, precipitating out pectin from the filtrate by addition of acetone, extracting L(+) tartaric acid selectively by complexation with tertiary amine and recovering from the amine layer by back extraction into aqueous layer in the presence of a diluent at around 70.degree. C. followed by concentration and drying of the aqueous layer and treating the raffinate layer from solvent extraction with activated carbon, anion exchange resin, and concentrating to yield sugar containing 70% sugars.
