Sensory Evaluation and Nutrition Ingredients Analysis of 7 Kinds of Sweet Potato Stem-apex for Vegetable
[Objective] To conduct sensory evaluation and nutrition components analysis on 7 kinds of sweet potato stem-apex for vegetables.[Method] Characters,nutrition and prospect of seven kinds of sweet potato stem-apex for vegetable were compared by sensory evaluation and nutrition ingredients analysis.The crude protein,crude fat,VC,chlorophyll and mineral elements were analyzed.[Result] The results showed that the appearances of all kinds of sweet potato stem-apex meet the requirement of vegetable.The comprehensive scores of sensory evaluation were significantly different among different varieties.The evaluations of Guangcai NO.1 and Tainong NO.71 were optimal.The contents of chlorophyll of 7 kinds of sweet potato leaves were 0.207-2.662 mg/g and VC contents were 190.0-400.0 mg/kg,the crude protein contents were 32.38-41.14 g/kg.The total fat contents of all kinds of sweet potato stem-apex were significantly different,and the highest variety was Guangcai NO.1 with 5.2 g/kg.[Conclusion] The present study provides evidence for wide planting and extending.
