Preliminary Study on the Relationship between Nutritional Quality and Grain Color of 69 Domestic Finger Millet Resources
In this study,12 nutritional indexes such as grain color(brightness:L*,red:a*,yellow:b*),starch and total flavone contents of 69 finger millets resources were determined,and the differences of nutritional indexes of grain color and the correlation between grain color and nutritional indexes were analyzed according to L*,a*and b*values.The results showed that the cluster analysis of 69 finger millet resources were separated into three groups:brown-yellow,brownness,and black-red.The average contents of protein,total amino acid,calcium,iron,potassium,magnesium,and VB2 of black red finger millets were higher than those of all other colors,and the magnesium content was significantly different from that of the other two kinds of grain colors(P＜0.01).The correlation results exhibited that both calcium and magnesium contents were negatively correlated with L*and b*(P＜0.01).The lower the L*and b*values,the higher the content of Ca and Mg.Total glucose was negatively correlated with L*value(P＜0.01),total starch content was negatively correlated with b*value(P＜0.05),and the rest were not correlated with grain color value.
