Influence of fermentation conditions on the quality of goat milk yogurt and technology optimization

In this paper,we used skim sheep milk powder as the raw material to prepare yogurt and discussed the influence of fermentation conditions on the quality of goat milk yogurt.The sensory evaluation and determination of physio-chemical indexes were analyzed,including acidity,water-holding capacity,viscosity,etc.The optimum process based on the single factor and orthogonal test were as follows:fermentation temperature 44℃,fermentation time 8 hours,inoculation volume 0.125%,sugar content 4%.The final goat milk yogurt was sweet and sour,tasty and delicious.
