The high acidity of subtreatment-1 of
treatment-I was due to that free L. casei and B. bifidum can produce
more than 1% acid as reported in Bergey’s Manual (1986). Thus the
microencapsulation technique of subtreatment-2 in the same
treatment lowered the acid produced by probiotics. In this respect,
Adhikari et al. (2000) reported that yoghurt made with normal
yoghurt starter and microencapsulated Bifidobacterium had
significantly lower acidity than yoghurt made with free Bifidobacterium
