【Abstract】 The processing technology of purple potato and wolfberry yogurt was studied. Fresh milk, purple potato and wolfberry were used as main materials in the experiments. The optimum fermentation conditions were determined by orthogonal experiments. It was concluded that the ratio of fruit juice and milk 5:5, inoculum 5%, sucrose 6%, fermentation temperature 42 ℃ and fermentation time 6 h. Under these conditions, purple potato and wolfberry yogurt with good quality was produced.更多还原
