The mixture was subsequently placed in a water bath to cool down to 43°C prior to inoculation with the starter cultures. The first portion of cooled mixtures of each of the two formulations was inoculated with 1% commercial yoghurt culture (50:50) mixture of Lactobacillus bulgaricus and Streptococcus thermophilus as described by Lee et al. (1990). A preculture of each of the two LAB isolates from nunu (Lactobacillus bulgaricus and Streptococcus thermophilus) was prepared; and the mixed culture inoculated into the second portion of cooled mixture of each of the premixes at 5% final volume as described by Murti et al. (1992). All the inoculated premixes were poured into plastic cups and incubated at 43°C to ferment for 12 hours. After incubation, the premixes were cooled in an ice bath, placed in a cabinet at 6±2°C until evaluation within 12 hours
