New-prebiotics-added milk slice and preparation method thereof

Abstract

The invention relates to the field of dairy product processing, and particularly relates to a new-prebiotics-added milk slice and a preparation method thereof. According to the new-prebiotics-added milk slice provided by the invention, based on 100 parts by weight of raw materials, the new-prebiotics-added milk slice comprises 10-20 parts of resistant starches and 0.1-0.2 parts of prebiotics, wherein the ratio of the prebiotics to the resistant starches is 1: (60-140). In the invention, the prebiotics and the resistant starches are added into the milk slice, and through adjusting the additive amounts and proportion of the prebiotics and the resistant starches, especially within a preferable range, the milk slice can achieve a synergistic effect, therefore, the new-prebiotics-added milk slice generates a more obvious effect on human health, and the stability of viable count of bacterial powder can be maintained during the storage period of the bacterial powder. So, the new-prebiotics-added milk slice provided by the invention is rich in nutrition, convenient to eat, and suitable for being taken by people in all age groups.

Description

technical field [0001] The invention relates to the field of dairy product processing, in particular to a milk tablet added with a new type of prebiotic and a preparation method thereof. Background technique [0002] Milk tablets are yogurt products made of milk as the main raw material, adding probiotics to the milk for fermentation, and then performing low-temperature spray compression. The yogurt product has long shelf life, convenient storage and transportation, simple production method, and can keep the activity of probiotics in the yogurt to the greatest extent and the function of the yogurt. [0003] The probiotic Bifidobacterium can reach the human intestinal tract in the form of live bacteria and play important physiological functions. The beneficial effect of bifidobacteria on the human body includes the following points: the cell wall of bifidobacteria interacts with the epithelial cells of the intestinal mucosa, binds tightly, and jointly occupies the surface of...

AI Technical Summary

Problems solved by technology

[0008] The present invention adds prebiotic resistant starch to milk tablets, but it is necessary to maintain a suitable ratio of resistant starch and probiotics. If the amount of resistant starch added is too small, after it reaches the intestinal tract, the beneficial bacterial strains in the intestinal tract will ferment The content of short-chain fatty acids produced by resistant starch is reduced, and the function of resistant starch will be affected; if the amount of prebiotics added is too large, it will not only affect the taste and flavor of the product, but also cause harmful bacteria in the intestine to ferment and resist Resistant starch, produce flatulence factors and other adverse effects on the gastrointestinal tract, therefore, to achieve the addition of resistant starch to milk tablets must overcome the above problems
