International Journal of Phytocosmetics and Natural Ingredients 2015, Vol 1, Suppl A: S1-S36 S1 ABSTRACT The treatment of tropical diseases, particularly gastro-intestinal/viral diseases in low income and rural areas have created a demand for oral rehydration salts with better taste, quality, accessibility and storage. The recommended use of fresh coconut is limited by availability, consistent quality and rapid nutritional deterioration. Reconstituted powdered products have not retained the natural flavor and are often unpalatable. This study evaluated the process of freeze drying fresh [F] coconut water at different maturity stages in its pure form and enhanced with natural fruit flavors (mango and passion fruit). Samples were frozen (-30 º C for 48 hours) and then vacuum freeze dried (VFD) using a Labconco FreeZone ® 2.5 Liter Freeze Dry System at a pumping speed of 5.0 m 3 /hour. The rehydrated crystals were analyzed for its electrolyte contents and vitamins using Atomic Absorption Spectrophotometer. The results indicated that the electrolytes balance increased with maturity of the coconut fruits, and that there were no differences between the mango and passion fruit juices. In some cases, the electrolyte content was higher in the fruit juices than the water. The general trend of the electrolytes were: P 1509 to 2191 (mg/L); Ca 160 to 499 (mg/L); Na .01266 to 0.00881 (mg/L); Mg 60.68 to 65.21 (mg/L); Fe <1.0 ppb to 0.1436 (mg/L); Zn 0.3071 to 65.93 (mg/L); Mn 2.08 to 80.2 (mg/L); Cu < 5 ppb to 0.419 (mg/L). The taste and shelf-life were also comparative and some cases better than the commercial rehydration salts.
