| 摘 要： | 研究了旋流与酸浆法两种甘薯淀粉的性能,并对其所制粉条的色泽、老化、膨胀系数、烹饪损失率和质构性质等进行了比较。旋流法甘薯淀粉的亮度、膨胀度(55～95℃)和溶解度(55～95℃)与酸浆法淀粉的相比明显偏低(p<0.05),而4℃下放置1周的老化速率明显偏高(p<0.05)。与酸浆法淀粉粉条相比,旋流法淀粉粉条的色泽和膨胀系数显著地降低(p<0.05),而其老化速率、拉伸形变及剪切应力显著升高(p<0.05)。

| Abstract: | The physico-chemical properties of sweet potato starches prepared by centrifugal cyclone separator(SC)and sour liquid processing(SS)were investigated.The color,retrogradation,swelling index,cooking loss,and textural properties of noodles were analyzed.The lightness,swelling power(55～95℃),and solubility(55～95℃)of SC were significantly(p<0.05)lower than those of SS.During one week storage at 4℃,SC pastes showed significant higher(p<0.05)retrogradation rate.The lightness and swelling index of SC noodles were lower than those of SS noodles.In addition,the retrogradation rate,tensile strength and shear stress of SC noodles were significantly higher(p<0.05)than those of SS noodles. |
