Comparison of the effects of the examples and the comparative examples
The products obtained in examples 1 to 4 and comparative examples 1 to 4 were subjected to sensory taste, the samples were subjected to a anonymous scoring method, 8 developers who had experience in milk product identification were invited to evaluate and score the overall taste (sweetness, smoothness, flavor and satiety) of the products (9 points each), and the higher the score, the closer the optimal characteristics of the products are. The sensory evaluation indexes and characteristic indexes are shown in table 1:
table 1: evaluation of taste preference and physicochemical stability index in various examples and comparative examples
Figure BDA0002518652820000101
According to evaluation, the products are not smooth enough in taste and have no natural burnt sweet flavor when the black tartary buckwheat tea is not added in the comparative examples 1 and 3; comparative example 3 increasing the amount of oat flour (ratio of vegetable protein to milk protein is greater than 1: 4) significantly increased the mouthfeel and bran feel, and decreased the mouthfeel smoothness; after the addition amount of the oat flour is reduced in the comparative example 2 (when the ratio of the vegetable protein to the milk protein is more than 1: 17), the product has smooth mouthfeel and normal flavor, but the satiety is reduced; in comparative example 4, after the suspension system (sodium carboxymethylcellulose or gellan gum) is removed, the product is prone to fat floating and precipitation problems during the shelf life.
It will be understood that modifications and variations can be made by persons skilled in the art in light of the above teachings and all such modifications and variations are intended to be included within the scope of the invention as defined in the appended claims.
