Abstract

Palm trees as non-timber forest plants can produce sap after going through the tapping process. Palm sap has been widely consumed by the public as a fermented beverage. However, this palm sap is easy to change in quality. Therefore, the purpose of this study was to analyze the pH value and color of palm sap during storage. Samples of palm sap were obtained from farmers in Sesaot, West Lombok, West Nusa Tenggara, Indonesia. The research parameters were changes in pH and color of palm sap after tapping. Research samples were stored at various temperatures of 15, 30, and 40 ºC. Observation data was carried out every 2 hours for 2 days of storage. The results showed that the pH levels and the color of the palm sap changed after storage. After 10 hours of storage, the pH level of palm sap changed from 7.0 to 2.6 at 40 ºC; 4.8 at 30 ºC; and 6.6 at 15 ºC. Palm sap stored at 15 ºC had the lowest decrease in pH value compared to 30 and 40 ºC. The higher the storage temperature, the greater the decrease in the pH value. Along with the decrease in pH value, the color of palm sap also decreased significantly at various storage temperatures.
