Quality characteristics and shelf- life of sugar substituted sterilized flavoured milk drinks

A study was undertaken to study the effect of mango pulp supplementation on the quality of low calorie milk drinks prepared using sucralose as sugar substitute and adding 10% mango pulp. The drinks were sterilized and stored at ambient temperature for determining their shelf life. A significant (p < 0.01) loss of ascorbic acid and reducing sugar content of the drinks occurred during storage for 75 days. Changes in color (L, a, b) values indicated enhanced browning and deterioration in appearance and flavor scores of the drinks. It was found that sterilized mango flavoured drinks (MFDs) were acceptable up to 60 days. Standard plate count, yeast and molds and spore formers were not detected throughout the storage of MFDs.
