不同生态环境对谷子营养品质和淀粉特性的影响
Effects of different ecological environments on the nutritional quality and starch characteristics of foxtail millet
摘要
Abstract
To clarify the influence of different ecological environments on the nutritional composition and starch characteristics of foxtail millet in the summer-sowing region of North China,nine foxtail millet varieties were selected as materials,and the changes of nutrient content and their effects on starch characteristics were studied at three different ecological environments in Chaoyang,Liaoning Province,Jinan,Shandong Province and Sanya,Hainan Province.The results indicated that there were significant differences in the nutrient content among varieties,environments and interactions.The crude protein content was the highest in Chaoyang,followed by Jinan and Sanya,showing an increasing trend with the increasing of latitude.The order of crude fat content from large to small was Sanya＞Jinan＞Chaoyang,showing a trend of decreasing with the increasing of latitude.The total starch content was the highest in Jinan,and the variation with latitude was not obvious.The order of amylose content from large to small was Sanya＞Jinan＞Chaoyang,showing a decreasing trend with the increase of latitude;The ratio of amylopectin to amylose was the highest in Chaoyang,and the trend was opposite to amylose.The carotenoid content was the highest in Jinan,which was significantly different compared with the other two sites.The 7 characteristic values of starch RVA spectrum were significantly affected by the planting environment.The influence of variety,location and variety interaction on peak time was not significant.The viscosity,final viscosity and subtractive value of thermo plasma were Sanya＞Jinan＞Chaoyang,showing a decreasing trend with the increase of latitude.The disintegration value and peak viscosity were the highest in Jinan of Shandong Province.The planting environment and variety displayed significant effects on the nutrient content and the characteristic value of starch RVA spectrum of millet.The cultivation environment significantly influenced the content of protein,fat,starch and carotenoid in foxtail millet.High latitude was beneficial to the accumulation of protein,while fat content decreased with the increase of latitude.In conclusion,the nutritional quality and starch characteristics of foxtail millet are greatly influenced by environmental effects.Therefore,according to the different characteristics of nutrition and taste quality of foxtail millet at different latitudes,the optimal variety suitable for planting in specific areas can be selected,and the producing areas of each high-quality varieties can be easily identified.关键词
