Abstract:Soybean oligopeptide powder and whole milk powder，as the main raw materials，can be supplemented with white sugar and orange juice to make milk beverages.The formula was optimized by single factor test and response surface test.The results showed the optimum formula of the orange-flavored soybean oligopeptide milk beverage was as follows：the mass ratio of soybean oligopeptide powder to whole milk powder of 1:8，white sugar at a ratio of 5%，orange juice at a ratio of 6.5%，and compound stabilizer at a ratio of 0.4%.The milk beverage produced under this condition has a creamy yellow color，a suitable taste and smell，and a good tissue state.
