摘　　要：为科学利用葡萄皮渣开发新型饲料资源,依据国家标准方法测定了葡萄皮渣的卫生指标、营养成分及氨基酸含量,并采用国际通用的方法对必需氨基酸进行分析。结果表明:葡萄皮渣卫生指标Pb、As、Hg、Cd、F、黄曲霉毒素、细菌总数、霉菌总数符合国家饲料卫生标准,常规营养成分中粗蛋白为12.0%、粗脂肪为8.4%、粗纤维为29.5%、粗灰分为3.2%、Ca为0.82%、总磷为0.08%。氨基酸含量丰富、种类齐全,总量为10.78%,必需氨基酸占比为34.88%,呈味氨基酸占总氨基酸43.43%。葡萄皮渣蛋白质的化学评分(CS)、氨基酸评分(AAS)、必需氨基酸指数(EAAI)、生物价(BV)、营养指数(NI)和氨基酸比值系数分(SRCAA)分别为43.3、47.7、65.8、60.0、7.9、76.3。葡萄皮渣第一限制性氨基酸含硫氨基酸不足,其他必需氨基酸平衡性较好,是一种有待开发的新型饲料资源。The paper aims to develop grape pomace as a new type of feed resource. We measured the hygienic index, nutrient content and amino acid composition of grape pomace by national standard methods, and analyzed the value of essential amino acids by international common methods. The results showed that: the grape pomace hygienic index, including Pb, As, Hg, Cd, F, aflatoxin, bacteria, total number of molds met the national standard of feed hygiene;the conventional nutrient contents in grape pomace contained crude protein of 12.0%, crude fat of 8.4%, crude fiber of 29.5%, crude ash of 3.2%, Ca of 0.82%, and total phosphorus of0.08%;the total amount of amino acids was 10.78%, with the proportion of essential amino acids accounted for34.88%, and the delicious amino acid accounted for 43.43%;the chemical score(CS), amino acid score(AAS),essential amino acid index(EAAI), biological value(BV), nutrition index(NI) and Score of Ration Coefficient of Amino Acid(SRCAA) of grape pomace protein were 43.3, 47.7, 65.8, 60.0, 7.9, and 76.3, respectively. Grape pomace, with well-balanced essential amino acids except insufficient sulfur-containing amino acids of the first limiting amino acid, is a new feed resource to be developed.
