Abstract

The invention belongs to the technical field of milk food preparation, and particularly relates to an additive-free normal-temperature yoghourt and a preparation method thereof. Main raw materials ofthe normal-temperature yoghourt only comprise three main components of liquid milk, a sweetener and nostoc sphaeroides, and addition of additional stabilizers and acidity regulators is not needed. Theproduct provided by the invention can be stored at normal temperature for 5 months, and the yoghourt has thick, pure and delicious flavor and mellow and smooth taste. After the product is placed at normal temperature for 5 months, the product basically has no phenomena of water seepage, bad flavor, protein coagulation and precipitation phenomena, and has stable mouthfeel and longer shelf life. Finally, it proves that the product has a reasonable formula, good flavor and smooth mouthfeel. According to the preparation method disclosed by the invention, the nostoc sphaeroides powder is subjectedto hydration and independent fermentation treatment, so that polysaccharide substances of the nostoc sphaeroides powder are effectively dissolved out, and bad flavor brought by the nostoc sphaeroidespowder is also modified. According to the invention, viscosity and stability of the product are successfully improved in a green mode, and the normal-temperature yoghourt with clean ingredients is prepared.

Description

technical field [0001] The invention belongs to the technical field of dairy food preparation, and in particular relates to an additive-free normal-temperature yoghurt and a preparation method thereof. Background technique [0002] Normal temperature yogurt is a kind of dairy product that is made of milk as the main raw material, which is rich in protein, calcium and other nutrients obtained after sterilization and fermentation, and then pasteurized to inactivate the lactic acid bacteria in yogurt. Normal temperature yogurt products are favored by dairy processors and consumers because of their unique taste and flavor, no need for refrigeration, and convenient logistics, transportation and storage. [0003] The choice of stabilizer in room temperature yoghurt is one of the key factors to determine its ability to be stored at room temperature and to be stable during storage. Normal temperature yoghurt in the prior art generally needs to add at least three or more stabilizers ...
