combination was A2B2C2D4. The product quality of
goat milk yogurt was the best when the amount of
sugar added was 7%, the inoculation amount was 3%,
the ratio of the 3 lactic acid bacteria was 1:1:3, and
fermentation temperature was 42°C. As shown in Table
6, factor B had a significant (P < 0.05) effect on the
result, whereas factor A, C, and D had no significant
effect on it. This is probably due to the small difference
levels between each factor or a large error of measurement
