渍害胁迫对芝麻籽粒及制油品质的影响
Effects of Waterlogging Stress on the Quality of Sesame Seed and Oil Product
摘要
Abstract
In order to investigate the effects of waterlogging stress on the quality characteristics of sesame seeds and oil,Yuzhi 11 and other 5 sesame varieties were applied as the materials for the mature seed quality analysis, sesame was irrigated 0,36 h continuously during flowering stage in the waterlogging nursery. Sesame seeds were collected in the mature period and analyzed from the appearance, nutritional components, minerals and oil prod-ucts. The results showed that the seed color of different sesame varieties varied with some extension under the wa-terlogging stress. The number of shrunken grains was increased. It decreased the commodity value of sesame. How-ever,it was not changed the seed length and deed width which average was about 3.00,1.80 mm respectively. The contents of crude fatty acids, proteins and total sugars in sesame seeds varied from-3.73%-2.03%,-0.10%--2.16%, and-0.93%-5.80% respectively. The contents of coarse fiber and ash in the treat-ments increased. The mineral contents of Ca,K,Mg and Na elements varied diversely in seeds under waterlogging stress. Among them,Ca element did not change regularly with different varieties. But the content of K, Mg and Na increased. The contents of arachic acid, linolenic acid and palmitoleic acid varied. The content of oleic acid and linoleic acid did not vary obviously. The change of sesame oil products mainly manifested in the basic increase trend of acid value and peroxide value (except the peroxide value of M5), the content of oleic acid, linoleic acid and palmitic acid did not change significantly, the content of arachidic acid, linolenic acid and palmitic oleic acid changed in an extent.The content of sesamin and sesamolin varied, depended on the genotypes of the different varieties.关键词
