Abstract: Using fresh pasteurized milk as the main raw material,the formula of milk gelato was optimized by single factor test and orthogonal test with the sensory evaluation as index.The results showed that the addition amounts of various raw materials for making 1 kg gelato were as follows：pasteurized fresh milk 650 g,light cream 120 g,plant fiber 65 g,structural base powder 70 g,white granulated sugar 60 g,skim milk powder 35 g.The milk gelato prepared under the conditions of this formula has the pure soft milk flavor,fine and smooth tissue, silky and soft waxy taste,dense and cool,moderate sweetness,rich nutrition,sensory score up to 90.4 points,the physical and chemical indexes and health indexes meet the requirements of relevant standards.
