Problems solved by technology

However, the protein particles of room temperature stirred yogurt are easy to precipitate under acidic conditions. At present, stabilizers are mainly added to the yogurt system to solve the problem of protein precipitation.
However, general stabilizers will cause the defects of rough taste and obvious pasty taste of fermented yogurt, so further research is needed to obtain room temperature stirred yogurt products with fine and smooth taste

Abstract

The invention provides normal-temperature stirring type yoghourt and a preparation method thereof. The normal-temperature stirring type yoghourt comprises: fermentation raw materials, which comprise the following components in parts by weight: 950-1050 parts of raw milk, 45-55 parts of white granulated sugar, 4-6 parts of whey protein concentrate, 8-12 parts of a compound stabilizer, 0.35-0.4 partof yoghourt essence, 0.4-0.5 part of milk essence and 0.28-0.35 part of herbal essence; and a fermentation agent, which is a mixed strain of streptococcus thermophilus and lactobacillus bulgaricus, and has an addition amount of 90-110 DCU / kg. The normal-temperature stirring type yoghourt provided by the invention is fine and smooth in mouth feel and free of pasty mouth feel.

Description

technical field [0001] The invention belongs to the technical field of yoghurt, and in particular relates to a normal-temperature stirring yoghurt and a preparation method thereof. Background technique [0002] Yogurt is divided into set yogurt and stirred yogurt. Set-type yogurt is a product produced by first filling and then fermentation without demulsification process, while stirred yogurt is a product produced by first fermentation and then demulsification, cooling, filling and other processes. Among them, the room temperature stirring yogurt is also called "sterilized yogurt". After it has been fermented, it has been heat-treated again to kill the live fungi in the yogurt. Therefore, it is more convenient to store and does not need to be refrigerated. It will not go bad for a long time, and it is very convenient to carry on long-distance travel. However, the protein particles of room temperature stirred yogurt are easy to precipitate under acidic conditions. At presen...
