Abstract

The invention discloses normal-temperature drinking type yoghourt and a preparation method thereof. The normal-temperature drinking type yoghourt comprises the following raw materials in percentage by weight: 56.6%-60% of concentrated raw milk, 1*10<6>-7*10<9>cfu/mL of a fermenting agent, 0.03-0.5% of a stabilizing agent, a proper amount of a sweetening agent and a proper amount of water, wherein the stabilizing agent is selected from one or multiple of pectin, soybean polysaccharide and gellan gum, and the percentage is the mass percent of the stabilizing agent, accounting for the total mass of the normal-temperature drinking type yoghourt. The preparation method comprises the following steps: (1) homogenizing the concentrated raw milk and milk powder and sterilizing to obtain a sterilized liquid mixture A; (2) cooling, adding the fermenting agent for fermentation, overturning a jar by back pressure, homogenizing and cooling again; (3) uniformly mixing with the sterilized liquid mixture A, adjusting the acidity, homogenizing so as to obtain a liquid mixture B, wherein the liquid mixture A comprises the stabilizing agent, the sweetening agent and the water; and (4) sterilizing the liquid mixture B. The normal-temperature drinking type yoghourt and the preparation method disclosed by the invention have the advantages that the requirements of heat treatment for the viscosity of the yoghourt and the adding amount of the stabilizing agent are effectively reduced, the obtained normal-temperature drinking type yoghourt is good in fluidity and smooth in taste and has no obvious layering condition after being stored for 6 months under the normal temperature.

Description

technical field [0001] The invention belongs to the field of fermented milk product processing, and in particular relates to normal temperature drinking yoghurt and a preparation method thereof. Background technique [0002] Milk is recognized as a food of great nutritional value all over the world. It is rich in protein, fat, carbohydrates and minerals. Fermented milk products obtained by adding bacteria to milk as a substrate have a nutritional value based on milk. In addition to adding live bacteria and metabolites that are beneficial to intestinal peristalsis and improving immunity, some proteins are decomposed into polypeptides and amino acids, and some fats and lactose are also decomposed into smaller compounds, which are more easily absorbed by the human body. absorb. [0003] Fermented milk drink, also known as yogurt drink, refers to a beverage prepared by fermenting yogurt with sugar water and stabilizers. It is usually sterilized by UHT and can be stored at room ...
