Researches on the technology of Cucumber and yogurt processing
Abstract:cucumber,milk powder , white sugar were used as raw material, the processing technology of Coagulation-type cucumber yogurt was studied. It was identified that the Optimum conditions Of cucumber juice’s color protection as following:the blanching temperature of 85℃, time of 4 min.The best recipe to produce cucumber yogurt is as following:the addition level of milk is 10% , the add content of cucumber juice is 20%,the addition level of white sugar is 6%.The fermentation temperature of 42℃,the fermentation time of 16h and the lactobacillus inoculum of 4% were the Optimum process parameters.

Keywords: Cucumber;yogurt ;ferment;process technology
