Abstract:
Grain amaranth has high nutritional value, contain higher protein (16-18%) than cereal grains and has significantly higher lysine content. A study was conducted on formulation of spray dried grain amaranth based malted milk powder. Grain amaranth was soaked, germinated, malted and blended with skim milk powder and slurries (20, 25 and 30%) were prepared & spray dried. The optimized grain amaranth malted milk powder had 0.385 g/mL bulk density and color value (L^*, a^*, b^*) of 85.99, 1.10, 13.945, and the moisture, water activity, water solubility, flowability (CI & HR) and pH values were found to be 3.1%, 0.215, 96.32%, (26.1% & 1.353) and 6.32, respectively. The spray dried grain amaranth malted milk powder found to have protein (32%), fat (2%), fibre (1.24%), ash (5.99%) and carbohydrate (60.2%), respectively. The calcium, phosphorus and iron content of malted milk powder was 1200, 820 and 22.8 mg/100 g, respectively. The malted milk powder produced with slurry of 25% concentration had best sensory acceptability upon reconstitution of spray-dried malted milk powder and it was kept for 3 months of storage.
