| 摘 要： | 以普通玉米淀粉和高链玉米淀粉(Hylon Ⅴ和Hylon Ⅶ)为研究对象,考察了湿热处理前后其抗性淀粉含量、直链淀粉含量、热力学性能、膨胀度及消化性等性质的变化.结果表明:湿热处理后3种玉米淀粉的抗性淀粉含量和直链淀粉含量均有所提高；湿热处理提高了3种淀粉的糊化温度和糊化焓,使糊化变得困难；湿热处理后偏光十字没有消失,...

| Abstract: | Normal and high-amylose(Hylon V and Hylon VII)corn starches before and after heat-moisture treatment were investigated in terms of resistant starch(RS) content,amylose content,thermal properties,swelling power and digestibility.The results show that the RS and amylose contents of the three kinds of starches all increase after the heat-moisture treatment,and that,the heat-moisture treatment improves the gelatinization temperatures and gelatinization enthalpies of the starches,which make it difficult for the ... |
