Abstract : Mango soy fortified probiotic yoghurt (MSFPY) was prepared by using blends of 78.3% toned milk, 14.5% soy milk and 7.2% mango pulp. Effect of yoghurt cultures Streptococcus thermophilus (ST), Lactobacillus bulgaricus (LB) and probiotic culture Bifidobacterium bifidus (BB), Lactobacillus acidophilus (LA) on physicochemical properties and sensory properties were studied using different inoculum levels as per Response Surface Methodology (RSM). The optimized concentration of cultures was found out to be 1.75%, 1.95%, 2.44% and 1.37% for ST, LB, BB and LA respectively which yielded an acceptable quality of MSFPY having acidity 0.73%, total solids 14.02%, syneresis 14.12% and scored 8.5 on hedonic rating.
