Formulasi Minuman Susu Asam dengan Biji Nangka sebagai Prebiotik

Abstract

Jackfruit seeds (Artocarpus heterophyllus Lam.) contain dietary fibre, so that its potential as prebiotic can be used to make acid milk drink. This research aimed to obtain the synbiotic drink formula that contain active lactic acid bacteria (LAB), preferable of hedonic level and its chemical properties were known. Treatments of this research were effect of the number of jackfruit seed flour added (4, 5, 6%(w/v)) and two LAB used (Lactobacillus plantarum and Lactobacillus brevis). Formula to be selected by viable number of LAB analysis, pH value, and sensory quality. Selected formula was fermented milk drink produced by L. brevis with jackfruit seed flour 4%(w/v)). Viable number of LAB of that formula was 10.59 log cfu/mL. The sensory quality of that formula was neutral until rather preferable for color, flavour, taste, texture, and overall. The formula has chemical content (%b/b), that were, moisture content 78.16%, ash content 2.34%, fat content 2.85%, protein content 3.15%, carbohydrate content 13.51%, and lactic acid content 1.73%.
