Acidity% in plain yoghurt samples were 0.90, 0.95, 1.06 and 0.98(F, A, B, C) respectively, while in case of fruit yoghurt samples were 0.92, 1.03 and 0.91(M, N, L) respectively. The mean coliform count/g in examined yoghurt samples was 1.85±1.01, 1.54 x102±0.07 x102 for plain yoghurt (B, C) while, 1.62 x10±1.12 x10 in fruit yoghurt (M).The mean staphylococci count/g in examined natural yoghurt were (F, A, B,C) 0, 1.45x10±0.95x10C, 8.85x10±8.01x10 and1.54 x102±1.02x102 ,respectively. While in fruit yoghurt (M, N, L) the mean values were 1.62X102 ± 1.12 X 102, 9.25X10 ±8.01X10 and5.54 X 10 ± 4.01 X 10. | ||
