Abstract

The invention discloses normal-temperature brown yoghurt and a manufacturing method thereof. The normal-temperature brown yoghurt is prepared from fresh milk, dextrose monohydrate, a compound stabilizer, acetylated distarch phosphate, white granulated sugar and lactobacillus strains, wherein compound strains added proportionally according to activity include streptococcus thermophilus, lactobacillus bulgaricus and lactobacillus paracasei. The method includes steps: controlling quality of fresh cow milk, preparing browning material milk, matching materials, browning, cooling, adding the compound stabilizer and the white granulated sugar, premixing, performing dry mixing, adding the acetylated distarch phosphate, pasteurizing, performing ultralow-temperature ultralong-time inoculated fermentation, matching the strains, inoculating, fermenting, demulsifying, cooling, sterilizing, cooling, filling and storing. By means of ultralow-temperature ultralong-time inoculated fermentation, the problem of normal-temperature storage and transport of the brown yoghurt is solved while problems of quality and flavor of the normal-temperature yoghurt are solved as well. By improvement of technical formulations and processes of conventional yoghurt, high freshness and long shelf lives of products are achieved, and application to the technical field of dairy products is realized.

Description

technical field [0001] The invention relates to a brown room-temperature yoghurt in the technical field of dairy products and a production method thereof. Background technique [0002] Yogurt has a unique flavor and rich nutrition, and is loved by consumers. Conventional yogurt has a short shelf life, and cold chain conditions are required for transportation, storage and sales, and the product sales range is limited. Commercially available yogurt is mostly milky white, with a single color tone and full color, fragrance and flavor, which can meet people's demand for yogurt products. The yogurt products developed by existing room temperature yogurt technology need to be further improved in color, flavor and nutritional properties. Maillard reaction occurs between protein and sugar in milk, browning the milk and producing a special burnt flavor. This special flavor can give people the pleasure of drinking and increase appetite. Yogurt products made by adding auxiliary mater...
