dc.description.abstract Symbiotic yoghurt was made by combination of probiotic culture (Bifidobacterium longum and Lactobacillus acidophilus) and non-probiotic bacteria (Lactobacillus bulgaricus and Streptococcus thermophilus) with instant soy bean flour as prebiotic source. This yoghurt was packaged in three different types of packaging namely HDPE, PET and glass bottle under three different temperatures (room temperature, 2-4°C and 7-9°C). Critical parameters of shelf life determination were titratable acidity, total of coliform bacteria, and organoleptic acceptance. Storage time caused decrease of symbiotic yoghurt quality which was characterized by increased titratable acidity and total of coliform bacteria also organoleptic deterioration. Shelf life of symbiotic yoghurt was determined based on how long the critical parameter was attained a minimum limit quality of yoghurt in SNI 2981-2009 about yoghurt. Shelf life of symbiotic yoghurt stored at room temperature with HDPE bottle was one day, whereas with PET bottle and glass bottle were 2 days. At 2-4 °C, the shelf life in HDPE and PET bottle was 21 days, whereas the shelf life in glass bottle was 14 days. At 7-9 °C, the shelf life in HDPE bottle was 7 days, whereas the shelf life in PET bottle and glass bottle were 10 days and 21 days respectively. The result showed that the best shelf life was obtained by used HDPE bottle and storage at 2-4 °C. en_US
