摘要: 【目的】 探明内蒙古种植的马铃薯品种的蛋白质含量、氨基酸组成和营养价值。【方法】 采用微波消解-液相色谱串联质谱检测氨基酸的方法,统计分析内蒙古2016—2019年收获季575份鲜马铃薯的含量。【结果】 不同马铃薯品种蛋白质含量0.95%~3.55%,平均值(2.10±0.11)%,与全国平均水平持平。每克蛋白质中17种氨基酸的总量分布在423.72~1 015.41 mg、必需氨基酸占氨基酸总量的43.2%,高于联合国粮农组织(Food and Agriculture Organization of the United Nations,FAO)和世界卫生组织(World Health Organization,WHO)规定的标准蛋白7.2个百分点。其中,鲜味氨基酸含量较高,不同品种间鲜味氨基酸变幅较大,后旗红品种鲜味氨基酸含量最高。【结论】 通过不同的评价方法证明,新佳2号、费乌瑞它和后旗红的必需氨基酸含量与模式蛋白的接近程度、氨基酸比值系数评分和营养指数评分排序均处于前3位,这3个品种不仅蛋白质含量高,其营养价值也更均衡,是优质的蛋白来源品种,可作为马铃薯蛋白加工的优选品种。

Abstract: 【Objective】 To explore the protein content,amino acid composition and nutritional value for different potato varieties in Inner Mongolia.【Methods】 The protein and amino acid composition of 575 fresh potatoes from the harvest season of 2016 to 2019 in Inner Mongolia were analyzed by microwave digestion - liquid chromatography tandem mass spectrometry.【Results】 The protein content of different potato varieties ranged from 0.95% to 3.55%,with an average value of(2.10±0.11)%,which was consistent with the national average.The total amount of 17 amino acids per gram of protein was 423.72-1 015.41 mg,and the ratio of essential amino acids to total amino acids was 43.2%,7.2 percentage points higher than the standard protein stipulated by the Food and Agriculture Organization of the United Nations(FAO)and the World Health Organization(WHO).Among them,the content of amino acids of umami was higher,the variation of amino acids of different varieties was larger,and the content of Houqihong variety was the highest.【Conclusion】 Through different evaluation methods has been proved that the Xinjia No.2,Favorita and Houqihong was in the top three for their essential amino acid content and the proximity of model protein,amino acid ratio factor score and nutrition index score sorting,the three varieties had high protein content,not only their nutritional value more balanced,also high quality protein source,could be used as optimization of potato protein processing varieties.
