Innovative beverages that serve well to the dietary requirement for children and adults as vegetarian quinoa milk were prepared in this study. These beverages recorded overall-acceptability score of 7.3 and 8.0 on the hedonic scale, which is means, moderately like and very like for quinoa like-milk and calcium fortified quinoa like-milk respectively. Moreover, some chemical and physical properties (pH, total soluble solids , separation rate and viscosity) for quinoa milk and calcium fortified like-milk seems to be closed to similar vegetarian milk products. Quinoa seeds contain valuable amount of crude protein (14.90%), crude ether extract (6.97%), ash (2.63%), carbohydrate (64.91%), crude fiber (2.71%) and energy value (307.61Kcal./100g). These important components make these seeds suitable for fortification of  the diets. The crude protein contents of quinoa milk and calcium fortified quinoa milk were 1.40% and 1.37, the crude ether extract contents were 1.58% and 1.60%, the ash contents were 0.22% and 0.35%,the carbohydrate contents were 3.39% and 3.70% and the energy values were 33.06 Kcal. and  37.32Kcal/ 100g, respectively.. The calcium fortified quinoa like- milk was higher in calcium and magnesium contents (163. and 67.11mg/100g ) than the quinoa milk (58.23 and 64.23mg/100g), respectively. Also the quinoa seeds and its beverages had satisfied amounts of essential amino acids such lysine (6.51, 0.64 and 0.58%), leucine (6.57, 0.73and 0.69%), phenylalanine (6.47, 0.46 and 0.44%) and methionine (4.43, 0.28 and 0.24%),respectively. The seeds and the both beverages had total phenolic components contents (101.35, 16.47 and 28.54 mg /100g) and antioxidants activity (87.90, 55.60 and 84.09%), respectively. The protein efficiency ratio, protein digestibility and nitrogen balance of the protein quality in quinoa like-milk and calcium fortified like-milk beverages closed to the casein quality in animal studies. The determination of calcium and magnesium in the blood serum of rats showed a significant increase of two minerals for the different groups. The rats which fed on the calcium fortified quinoa milk recorded the highest minerals contents.
