the sensory score is 95, and the viable count reaches 108 to 109 cfu/mL when the optimum fermentation conditions were used. The content of short-chain and medium-chain fatty acids decreased significantly (P < 0.05) and the smell of goat milk was weakened in goat milk fermentation with the optimum fermentation conditions compared with raw goat milk and goat milk fermentation with L. rhamnosus GG through the analysis of goat milk yogurt fatty acids by a gas chromatograph. The resulting goat milk yogurt features
