Nutritional components of main cultivars of Cyperus esculentus in Inner Mongolia.

The basic nutrients, fatty acid composition, V_E content and mineral elements contents of four cultivars of Cyperus esculentus were measured with main cultivars of Cyperus esculentus (Shengmo No. 1, Zhongyousha No. 1, Fengchan No. 1 and Daqi No. 1) in Inner Mongolia as materials to analyze and compare the differences in nutritional value and quality of different cultivars of Cyperus esculentus. The results showed that there were differences in the basic nutrients of four different varieties of Cyperus esculentus, but they were all rich in starch (21.15%-25.40%), dietary fiber (20.15%-21.95%), fat (23.35%-25.60%) and total sugar (17.10%-17.95%), and could be used as raw materials for extracting starch, sugar and fat. The fatty acid composition of four varieties was basically the same, mainly oleic acid (9.1200-10.6000g/100g), linoleic acid (0.0518-1.5150g/100g) and palmitic acid (0.0378-1.9950g/100g), which could be used as raw materials for the production of oleic acid and high-quality edible...
