摘要
目的:研究淮山鲜薯去皮生食的可食性。方法:以桂淮2号、5号、6号鲜薯为材料,测定淮山鲜薯的营养成分,检测其毒性、重金属含量、农药残留等,评价生食口感、食味及安全性。结果:淮山鲜薯营养丰富,含淀粉17.09%、蛋白质2.61%、可溶性糖5.38%、氨基酸总量1.68%(共18种),其中7种为人体必需氨基酸,Fe、Zn、Cu含量分别为3.9、3.12、1.59mg/kg;淮山鲜薯重金属含量及农药残留量符合无公害蔬菜技术标准,安全,无毒性;淮山鲜薯去皮生食被受试人群接受。结论:淮山鲜薯去皮生食,营养丰富、安全。
Objective： To analyze the edibility of Huaishan fresh yam （Dioscorea opposita Tbunb.）. Method： Three varieties of yam Guihuai No.2, Guihuai No.5 and Guihuai No.6 were used as test materials. Taste and safety of fresh yam were evaluated by analyzing the contents of major nutrients, heavy metals and pesticides and the toxicity as well. Result： Yam has rich nutional components, including 17.09% starch, 2.61% protein, 5.38% soluble sugar and 1.68% gross amount of amino acids specifically 18 amino acids among which there are essential amino acids required by human beings. The contents of Fe, Zn and Cu are 3.9, 3.12, 1.59 mg/kg, respectively. The contents of heavy metals and pesticides in yam are found agreed with the technical criteria of vegetables. Eating fresh yam could be accepted by different tested populations. Conclusion： Fresh yam has rich nutrition value and is suitable for fresh food use with safety.
