Abstract

The invention relates to red date wolfberry fruit yoghourt and a making method of the red date wolfberry fruit yoghourt. According to the technical scheme, fresh milk is filtered, purified and cooled to 0 DEG C-5 DEG C, then passes through a purified milk separator to separate out fat and is proportionally added into skimmed milk to be prepared into standard milk; fresh red dates are added according to a formula and subjected to variable temperature and pressure difference puffing drying and superfine grinding to obtain red date powder, and the fresh wolfberry fruits are subjected to variable temperature and pressure difference puffing drying and superfine grinding to obtain wolfberry fruit powder, a stabilizer and a sweetener; ultrahigh-temperature short-time sterilization is carried out for 4 s-6s at the temperature of 137 DEG C, the product is cooled to the temperature of 34 DEG C-40 DEG C, 1.2 g/L-3.5 g/L chymosin is added, the product is inoculated with a fermentation agent and fermented for 8 h-16 h at the temperature of 35 DEG C-45 DEG C, and then the red date wolfberry fruit yoghourt is obtained. The problem that vegetable protein and milk protein are difficult to combine is solved by a modern scientific and technological means, the red dates and the wolfberry fruits high in nutrition value and healthcare value are added into the milk and fermented through the fermentation agent, and then the red date wolfberry fruit yoghourt with the high healthcare function is produced.
