Abstract

A grain of eight selected hybrids from the Maize Research Institute Zemun Polje was used as the subject of this study. The kernel structure, physical properties and chemical composition of the grain and starch (amylose content) were analyzed before the laboratory wet milling process for starch extraction. The in vitro enzymatic digestibility of the isolated starch was also determined. The wet milling properties were later correlated to the physicochemical characteristics of the grain. The results showed that hybrid ZP 677 had the highest starch yield, followed by hybrid ZP 704wx, while the highest starch recovery was observed for hybrid ZP 341. The highest bran yield (10.52%) was obtained by hybrid ZP 434, and the highest germ yield (8.86%) by hybrid ZP 172/8. The correlation analysis showed that starch yield was positively correlated to 1000-kernel weight and crude fiber content, while oil content negatively influenced starch extraction and yield. The starch digestibility was negatively correlated to the amylose content. These findings can be useful for the starch processing industry as well as in the production of ethanol and alcoholic drinks.
玉米杂交种湿磨特性研究
从Zemun Polje玉米研究所挑选的8个杂交种作为本研究的对象。在实验室湿磨法提取淀粉前,对籽粒结构、籽粒物理性质和籽粒化学组成(直链淀粉含量)进行了分析。测定了分离淀粉的体外酶消化率。湿磨性能后来与晶粒的物理化学特性相关联。结果表明,杂交种zp677淀粉产量最高,zp704wx次之,zp341淀粉回收率最高。杂交种zp434的麸皮产量最高(10.52%),zp172 /8的胚芽产量最高(8.86%)。相关分析表明,淀粉得率与千粒重和粗纤维含量呈正相关,而含油量对淀粉提取率和得率呈负相关。淀粉消化率与直链淀粉含量呈负相关。这些发现对淀粉加工业以及乙醇和酒精饮料的生产都很有用。
