Formulation 4 obtained highest mean score in taste, texture and overall acceptance. Proximate analysis carried out on formulation F4 and also a control to compare the difference among them. The milk sample contain 76.20±0.034% of moisture, 0.38±0.906% of ash, 1.35±0.018% of fat, 2.11±0.016% of protein, 1.92±0.352% of dietary fibre and 18.04±0.744% of carbohydrate. Milk sample has total energy value of 96.59 kcal or 408.82 kJ per 100ml which lower than in control. Microbiological test was carried out for both total colony count in both total plate count and yeast and mould count. pH value is found to increased first from 6.72±0.006 to 7.05±0.006 and decreased back to 5.92±0.300 along the storage period.
