Development and evaluation of whey based grapes and papaya drink
Whey is nutritious by-product of cheese industry which is dumped into fields, canals and rivers in Bangladesh. It has biological active peptides, proteins and other functional characteristics, due to which it could be used in different food products such as infant formula, beverages and sports nutrition products. Grapes and papaya are rich source of sugar, vitamins, bioactive compounds, dietary antioxidants and fructo-oligosaccharide. They improve the mineral absorption, decrease the serum cholesterol level and stimulate the intestinal microflora due to their prebiotic effects. The current study is being planned to develop low cost nutritive whey-based fruit drink in Bangladesh. Grapes and papaya will be added in the whey with different ratio for development of suitable drink. The drinks will be pasteurized or unpasteurized filled in bottles and keep in refrigerator for the period of 15 days. During storage drinks will be evaluated for physicochemical attributes (ash, pH, crude fat, crude protein, acidity, solid not fat, viscosity and total solids), Microbial (TVC and Coliform) and sensory evaluation (appearance, taste, flavor and over all acceptability) will also be came out during storage. Consequently, the obtained data will be analyzed statistically following two factors under CRD design.
