Abstract

The invention provides a low-lactose yoghurt with a long shelf life. The raw materials for making it include: 60 to 98.9 parts by weight of milk, 0.01 to 0.5 parts by weight of an emulsifier, 3 to 14 parts by weight of a thickener and 7 to 12 parts by weight of sugar; And the emulsifier is one or more combinations of sucrose fatty acid ester, glyceryl monostearate, sodium stearoyl lactylate and glyceryl distearate; the thickener is pectin, sodium caseinate , agar, gelatin, modified starch, gellan gum, propylene glycol alginate, xanthan gum, or a combination of several. The low-lactose long-shelf-life yoghurt has good stability. The present invention also provides a method for preparing the above-mentioned low-lactose long-shelf-life yogurt, which controls the fermentation temperature and performs secondary sterilization, and the low-lactose long-shelf-life yogurt prepared by the method has better stability.

Description

Technical field [0001] The invention involves a low lactose yogurt, especially a low lactose long shelf life yogurt and its preparation method with a long shelf life. Background technique [0002] Conventional yogurt affects the shelf life of yogurt due to its unable to avoid post -acidification problems.In order to extend the shelf life of the yogurt, the most effective way is to make the product after secondary sterilization treatment.After the secondary sterilization treatment, yogurt will decrease viscosity, protein degeneration, milk clearing, weakened aroma, etc., resulting in a decrease in stability.At present, the stability of the long -shelter yogurt is often improved by adding a specific stabilizer.For example, in April 2011, the 112nd article "Research on the Research on the Compound Stabilizer of the Long Sub -Book Period Yogurt".However, in the process of preparing low lactose long shelf life, due to the low lactose content, the product stability is not effectively i...
