| Popis: | Rujak kawista sauce is one of the typical Indonesian foods made from palm sugar, tamarind, bird’s eye chili, nuts, and special fruits of kawista to enhance the flavour. There is no information about the shelf-life of rujak kawista sauce to date. Therefore, it is necessary to conduct a study on the storage time of the rujak kawista sauce to determine the product’s shelf life. This study used the ASLT method to determine the shelf life of rujak sauce. The sauce was stored at temperatures of 30°C, 40°C, and 50°C within 21 days storage time and was analysed every seven days. The analytical methods used to support the ASLT method are TBA, moisture content, FFA, total dissolved solids and pH. The result showed that TBA value was 0.046-0.19 mg malonaldehyde/kg, moisture content was 16.68-20%, FFA was 0.66-0.80%, total dissolved solid was 17.9-21.1°Brix, and pH was 3.1-3.5. Based on Arrhenius calculations, the shelf-life of rujak kawista sauce was two months. |
