Abstract:In this paper, using date juice, Chinese caterpillar fungus fermentation liquid, whole milk powder as the main raw material, using DVS strain as fermentation agent, on the solidification type Chinese caterpillar fungus jujube yogurt and mixing type Chinese caterpillar fungus jujube yogurt production technology was studied, the solidified Cordyceps jujube yogurt optimum process parameters were: jujube juice volume 18%, Chinese caterpillar fungus fermentation liquid is added volume 12% in 9%, the quantity of sugar, milk powder added 12%, compound stabilizer added 0.2%, the sterilization method of 90 ° C, 15min, 0.2% inoculation quantity, culture time 10h, culture temperature 42 ° C, ripening time 12h; mixing type Chinese caterpillar fungus jujube yogurt optimal technological parameters for: whole milk powder: water 1:7, jujube juice content 19%, addition of 9% cordyceps. This test prepared yogurt flavor, delicate taste, tasty and refreshing texture, uniform, rich red dates and Cordyceps flavor, but also has certain nutrition and health function, and very broad prospects for development.
