Different package treatments on fresh-cut taro(Colocasia esculena(L.
与对照(普通塑料薄膜包装)、聚乙烯塑料薄膜(PE)包装相比,4℃贮藏的前12天,真空包装(VP)能较好地保持鲜切芋头的可溶性固形物含量(TSS)和淀粉含量,褐变度、丙二醛(MDA)含量和多酚氧化酶的活性较低,而超氧化物歧化酶活性较高。
The physical and chemical properties of taro starch were systematically studied,dealing with granule morphology,X-ray diffraction pattern,molecular distribution,gelatinization and paste viscosity.
本文研究了芋头淀粉的性质,实验采用电子显微镜拍摄了芋头淀粉颗粒的形态;运用X射线衍射仪测定了X-光衍射图样及结晶结构;通过重结晶法制得纯度较高的芋头直链淀粉和支链淀粉,利用高效液相色谱仪测定了芋头淀粉及其直、支链淀粉淀粉的重均聚合度、数均聚合度、分子量分布及分散度等,并与大米淀粉进行了比较。
The optimal condition was obtained for production of soluble dietary fiber from taro seedling by orthogonal experiment:temperature was 80 ℃,pH=6.
