A kind of drinking yoghurt at normal temperature and its preparation method

Abstract

The invention discloses normal-temperature drinking type yoghourt, which is prepared from the following raw materials in percentage by mass: 80 to 86 percent of fresh milk, 7 to 12 percent of white sugar, 0.5 to 2 percent of lactalbumin powder, 0.4 to 0.7 percent of pectin, 0.04 to 0.25 percent of agaragar, 0 to 0.03 percent of gellan gum, 0 to 0.05 percent of food flavoring and the balance water. The normal-temperature drinking type yoghourt provided by the invention has the advantages that more than 80 percent of pasture high-quality fresh milk is used as the main raw materials; the lactalbumin powder and the white sugar are added; food additives such as the pectin, the agaragar and the gellan gum are used as auxiliary materials; firstly, the milk is preheated, and is mixed with the raw materials such as the lactalbumin powder, the white sugar, the agaragar and the gellan gum; the materials are subjected to homogenizing, sterilization, cooling and fermentation for use. Through the secondary proportioning process, the pectin is singly dissolved and cooled and is then mixed with yoghourt; the 75-110 DEG C and 5-30s pasteurization heat treatment can be simultaneously performed. The normal-temperature drinking type yoghourt has the advantages that the requirement of a national standard of acidified milk that the flavor yoghourt needs to contain more than 80 percent of raw material milk is met; the stabilizing agent addition is reduced; the flowability of the produced yoghourt is good; the mouthfeel and the state thickness degree are proper.
