ABSTRACTThe objective of this research was to study the effect of L. acidophillus concentration on fermented soymilk quality. The experiment used a completely random design with L. acidophillus concentration as a treatment. Three levels of L. acidophillus concentration as probiotic bacteria, i.e.: 1, 2, and 3 % (w/w) were used in this research as addition of yoghurt bacterial culture (S. thermophilus and L. bulgaricus). A control is done for yoghurt without L. acidophilus addition. The result showed that the level of L. acidophillus concentration has a significant effect on pH, lactic acid content and sensory analysis (overall performance acceptability). The best treatment is 3% of L. acidophillus with the product properties of pH 4,45, lactic acid content 0,75%, solid content 11,20% and water content 88,80%.Keywords : probiotics, synbiotics, soymilk and L.
