英文摘要	The effects of the ratio of acetic anhydride to inulin,inulin concentration and reaction temperature on inulin acetate ester were studied by single factor experiments with the degree of substitution（DS） as measurement index.The response surface method was used to optimize the synthesis process conditions,and the optimal conditions were as follows:the ratio of anhydride to inulin of 4:1,the concentration of 30%,the temperature of 40℃.Under these conditions,the experimental DS was 3.04±0.06.The prepared inulin acetate ester was characterized by FT-IR and 1H NMR.The FT-IR spectra results showed that the inulin acetate ester had new characteristic absorption peaks of carbonyl（—C=O）,methyl（—CH3）and ether bond（—C—O—C）.In the 1 H NMR spectra,the methyl（—CH3） proton peak on the acetic anhydride molecule appeared near 2.0 ppm,and the chemical shift of the proton peak on the sugar ring moved to the lower field due to the connection of the carbonyl group（—C=O）,which indicated that inulin was successfully acetylated.The total short-chain fatty acids in the fermentation broth with inulin acetate ester and inulin as carbon sources were 86.00 mmol/mL and 110.22 mmol/mL,respectively（P<0.05）.Compared with the inulin,the acetic acid content in the inulin acetate fermentation broth increased significantly and the butyrate content decreased significantly（P<0.05）.The results showed that inulin acetate ester could be used as a carrier of short-chain fatty aeids,which could be produced by fermentation and provided theoretical basis for improving intestinal and body health.
