The area ratios of 980/1022, 980/1047,(980+1047)/1022 and 980/(1022+1047) cm^(-1) were decreased as the degree of acetification increased which indicated that acetification induced a decrease of crystallinity of starch. And the crystal structure changed from A-type to V-type. For the cross-linking of POCl3, the area ratios of 980/1022, 980/1047,(980+1047)/1022 and 980/(1022+1047) cm^(-1) were also decreased as the degree of cross-linking but the decrease was little compared to that of acetification. The result indicated that cross-linking of POCl3 had little effect on the starch crystal structure.

The results showed that the Mulberry fruit surface carried large numbers of yeast but little other mixed fungi; ethanol fermentation reached the peak value in 48h'; before vinegar production the acetification bed breeding took 9~10d, but the vinegar fermentation cycle was only about 24h during production .
