摘  要：
[目的]对7种菜用甘薯茎尖进行感官评价和营养成分分析。[方法]通过对7种菜用甘薯茎尖进行感官评定,并对粗蛋白、粗脂肪、维生素C、叶绿素和矿物元素等成分进行分析,比较不同品种菜用甘薯茎尖作为菜用的特点、营养和前景。[结果]分析表明,7种甘薯茎尖外观均符合菜用要求,不同品种甘薯茎尖的食用感官综合评分差异较大,广菜薯1号和台农71号的食用感官评价最优。7种菜用甘薯叶中,叶绿素含量在0.207~2.662 mg/g;维生素C含量在190.0~400.0 mg/kg;粗蛋白含量范围为32.38~41.14 g/kg;总脂肪含量差异较大,最高为"广菜薯1号"(5.2 g/kg);镁、钾、钠、锰、铜、铁等矿物元素含量绝大多数高于甘薯茎块和常见蔬菜。[结论]研究可为不同品种菜用甘薯茎尖的大面积种植和推广提供依据。

摘  要：
[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 VCcontents 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.
