The present study aimed with the use of artificial sweetener (Aspartame) as substitute for sugar at 25, 50, 75 and 100 percent level in flavoured milk preparation. In microbial quality analysis of dietetic flavoured milk samples, the standard plate count (cfu/ ml) of dietetic flavoured milk samples were 78 × 10-4, 63×10-4, 51×10-4, 23×10-4 and 21×10-4 for control treatments T1, T2, T3, and T4 respectively. Analysis of data showed significant difference (p<0.01) between control and treatments indicating that addition of aspartame tablets and sugar at different level produce significant change in the standard plate count. There was no growth of Coliform in control and treatments T1, T2, T3 and T4 indicating that addition of aspartame tablets and sugar at various levels dose not promote the Coliform growth. Analysis of data with regard to yeast and mold count (cfu/ gm) showed no significant difference between control and treatments indicating that addition of aspartame tablets and sugar at different level produce significant change in the yeast and mold count due to minimal processing of dietetic flavored milk during preparation and contain other ingredients rather than sugars. The sensory qualities such as color, flavor, and taste of the control and treatment dietetic flavored milk revealed no significant change in the sensory score of the product up to 75 percent replacement of sugar with aspartame.
