【摘要】 为了给消费者提供芸豆营养价值的指导,以黑龙江主栽芸豆品种En、紫荆花、白沙克、日本红、西班牙白、英国红为研究对象,采用比值系数法评价芸豆蛋白质的营养价值。试验结果表明,芸豆蛋白质的等电点在p H4.0左右;6种芸豆蛋白质含量为17.91%~22.03%,脂肪含量为2.56%~8.46%,总糖含量为4.50%~5.42%;英国红、En、白沙克芸豆蛋白质的氨基酸评分(AAS)分别为31、40、53,必需氨基酸指数(EAAI)分别为70.34、48.47、67.32,氨基酸比值系数分(SRCAA)分别为65.46、72.48、77.16,生物价(BV)分别为64.97、41.13、61.18,营养指数(NI)分别为67.41、44.72、62.98。芸豆蛋白质营养分析表明,芸豆蛋白的必需氨基酸组成符合FAO/WHO标准模式,说明芸豆蛋白质是一种营养价值丰富、容易消化的优质蛋白资源。更多还原

【Abstract】 In order to provide nutritional value guidance of kidney beans to consumers,major kinds of kidney bean in Heilongjiang province,the En,Zijing hua,Baishake,Japanese red,Spain white,the British red kidney bean were as raw materials.Ratio coefficient method was used to evaluate kidney beanprotein nutritional value.The Results showed that kidney bean protein isoelectric points were around p H4.0.Protein,fat and total sugar contents of the six kinds of kidney beans were among 17.91%~22.03%,2.56%~8.46%,and 4.50%~5.42%.The a mino acids score(AAS) of the British red,En and Bai Sha ke were 31,40 and 53.The essential a mino acids index(EAAI) of them were 70.34,48.47 and 67.32.The score of ratio coefficient of a mino acids(SRCAA) were 65.46,72.48,77.16.The biological value(BV) were 64.97,41.13 and 61.18.The nutrition index(NI) were 67.41,44.72 and 62.98.Kidney bean nutrition evaluation analysis showed that kidney bean protein composition of essential a mino acids in accordance with FAO/WHO standard mode,explain kidney bean protein was a kind of nutritional value,easy to digest the rich high quality protein resource.更多还原
