淀粉

The structure and characteristics of corn resistant starch were determined, including granule structure, crystallization, thermal characteristic, molecular weight, iodine absorption curve and amylose content.

对玉米抗性淀粉的结构和性质进行了测定，包括颗粒结构、结晶结构、热特性、分子量、碘吸收曲线及直链淀粉含量。

The area ratios of 980/1022, 980/1047,(980+1047)/1022 and 980/(1022+1047) cm^(-1) were decreased as the degree of acetification increased which indicated that acetification induced a decrease of crystallinity of starch. And the crystal structure changed from A-type to V-type. For the cross-linking of POCl3, the area ratios of 980/1022, 980/1047,(980+1047)/1022 and 980/(1022+1047) cm^(-1) were also decreased as the degree of cross-linking but the decrease was little compared to that of acetification. The result indicated that cross-linking of POCl3 had little effect on the starch crystal structure.

随着醋酸酯化取代度的增大，980/1022、980/1047、(980+1047)/1022和980/(1022+1047)的相对峰面积的比值均呈现下降趋势，表明醋酸酯化改性会导致淀粉结晶程度降低，结晶形态从A型转变为V型；随着交联度的增大，980/1022、980/1047、(980+1047)/1022和980/(1022+1047)的相对峰面积比值均呈现下降趋势，但下降程度较小，表明三氯氧磷交联对淀粉结晶结构影响不明显。

The results showed that compared with soil culture, the root cap was not obvious with less amyloplast and polysaccharose substance under water culture. The root epidermis under water culture was thinner than that of soil culture, with little root hair or not, in which cortex parenchyma tissue developed with big cell, solution proliferative aerenchyma in intercellular space, and thin cell wall. However, the root cap under soil culture was big, with strong PAS reaction and no aerenchyma tissue.

结果表明：水培后根冠不明显，淀粉体较少，多糖类物质较少而土培根根冠体积较大，淀粉体较多，多糖类物质多，土培根PAS反应强烈；水培根表皮厚度比土培根小，水培根根毛少或退化消失；水培根皮层薄壁组织发达，细胞大型，壁薄，细胞间隙中含有溶生性通气组织，土培根皮层未见通气组织。

两性淀粉作为一种重要的变性淀粉新品种，拥有良好的使用性能和广阔的应用前景。

A new type of dimorphic denature starch cationic starch with lauril glucoside was synthesized by reaction of cationic starch with lauryl alcohol at the presence of emulsifier and catalyst.

在乳化剂和催化剂作用下，以阳离子淀粉和月桂醇为主要原料，合成了一种新型高取代度的双变性淀粉——阳离子淀粉月桂基糖苷。

Using azoalbumin as a substrate, the activity of endopeptidase was enhanced by low concentration MJ and inhibited by high concentration MJ.

高浓度的MJ在早期能促进去胚水稻种子淀粉的降解，在晚期却抑制淀粉降解，而低浓度的MJ一直抑制淀粉降解。
