Abstract

Hybrid coconut (KHINA-1) has high potential since its water is sweeter and has stronger aroma but no economic value. In this study, the major macro and micro nutrients of hybrid coconut and tall (Pangandaran) coconut water as a base material for an isotonic drink were compared. Hybrid has higher brix, fructose content, minerals content, antioxidant activity, and total phenolic content, but lower pH value and vitamin B6. Sensory test of fresh coconut water includes intensity profiling and hedonic overall acceptance test using trained panelist was conducted. It was found that hybrid coconut water had a higher degree of acceptance. The shelf-life of fresh coconut hybrid fruit was determined in room temperature and refrigeration temperature. The result was 18 days in room temperature and 15 days in refrigerated temperature before sensory aspect unacceptable. Cold sterilization using microfiltration membrane successfully increased the shelf-life of coconut water. The isotonic drink product fulfilled Indonesian National Standard in terms of pH value, total sugar, microbial contaminants, and heavy metal contaminants; however, minerals content failed. The degrees of acceptance for hybrid coconut isotonic drink lied between like moderately and like very much. This study showed that hybrid coconut water is very potential as a base material for isotonic drink; however, the challenge was potassium and sodium content.
