Comparative Study on Grain Composition of Different Varieties of Maize
Anstract:In order to investigate the content and composition of nutrients in different maize(Zea mays L.)grains and the relationship between the content of each component,the content and correlation of starch,water,protein,fat,vitamin C(Vc)and reducing sugar in 15 maize varieties were analyzed.The results showed that starch content was from 70.45 to 74.30 g/100 g,water content was from 13.46 to 14.73 g/100 g,protein content was from 7.60 to 11.38 g/100 g,fat content was from 3.27 to 5.14 g/100 g and reducing sugar content was from 2.56 to 3.59 g/100 g,the Vc content was from 2.32 to 7.29 mg/100 g.Correlation analysis showed that Vc content was negatively correlated with protein content,starch content was negatively correlated with Vc content,but fat content was positively correlated with water content.Principal component analysis showed that the composite scores of the 15 maize varieties were Zidan805,Shanyu16,Huinongdan15,Longyu168,Shanyu12,Huinongdan No.3,Jinbaidan No.3,Longdan1701,Xinzhongyu No.4,Xinzhongyu No.7,Mengyu89,Longbai No.1,Longyu1708,Longyu1609 and Xinzhongyu666 in order from large to small.
