水热处理温度对玉米淀粉-绿原酸复合物结构及消化性能的影响
Effect of heat temperature on the structures and digestibility of corn starch-chlorogenic acid complexes
摘要
Abstract
Corn starch-chlorogenic acid complexes were prepared under 60℃,70℃,80℃and 90℃,respectively.The chlorogenic acid content,complex index(CI),crystal structure,in-vitro digestibility were studied,to investigate the effect of temperature on the formation and digestibility of corn starch-chlorogenic acid complexes during hydrothermal treatment.The results showed that as the heat temperature increased,the CI of starch increased from 4.27%to 10.65%gradually,the chlorogenic acid content in the complexes was increased first and then decreased with a highest content of 6.13 mg/g being prepared at 80℃.While excessive chlorogenic acid could promote the formation of double helix structure in corn starch,it hindered the reformation of ordered crystal structures.The structural changes in corn starch-chlorogenic acid complexes as the heat temperature increased would gradually enhance their gelatinization stability and resistance to digestion,and the resistant starch(RS)content in the complexes increased from 20.49%to 30.69%.Therefore,the interaction between corn starch and chlorogenic acid could be adjusted by controlling the heat temperature,which in turn modulates the digestibility of corn starch.关键词
