Abstract

The objective of this research was to know viability of lactic acid bacteria and characteristic of pineapple peel extract yoghurt during storage. Yoghurt cultures, Streptococcus thermophillus and Lactobacillus bulgaricus were added to extract of pineapple skin that incubated at 37oC for 36 hours. After that lactic beverages were added by 35% (v/v) fructose 55% (v/v). Streptococcus thermophillus and Lactobacillus bulgaricus were tested for viable and characteristic of yoghurt yield during 0, 7, 14, 21, 28 days storage in the refrigerated and room temperature. The experimental design was independently replicated 3 times in a completely group randomized design. All analysis were done in duplicate. The result showed that viability of lactic acid bacteria increased during 7 days storage and after that decrease until the end storage in both temperature. Temperature of storage was significantly affect to the viscocity, pH, taste, flavour, and whole acceptance, but there is no significantly affect to viability of lactic acid bacteria and appearance of yoghurt. Storage time was significantly affect to the viability of lactic acid bacteria, viscocity, flavour, and appearance of yoghurt, but there is no significantly affect to pH, taste, and whole acceptance. Storage for 7 days in room temperature still has pineapple peel extract yoghurt characteristic that accepted by consument. The panelist prefer to yoghurt pineapple skin kernel storage in refrigerator temperature than in room temperature.
