摘　　要：探讨苹果渣的营养成分,为苹果渣的综合利用提供依据.采用干燥法、索氏抽提法、酸水解法、凯氏定氮法、乙炔火焰原子分光光度法、范氏法等对苹果渣水分、灰分、脂肪、蛋白质、淀粉、膳食纤维、氨基酸、矿物质等成分进行了测定.结果显示:苹果渣水分含量为3.50±0.32 g/100 g,灰分含量为2.49±0.41 g/100 g,脂肪含量为7.32±0.23 g/100 g,蛋白质含量为6.57±0.26 g/100 g,淀粉含量为2.37±0.33 g/100 g,膳食纤维含量为77.40±0.51 g/100 g.蛋白质中可以检测出17种氨基酸,总含量为6.23×10^(4) mg/kg,其中必需氨基酸占所含氨基酸总量的质量分数为36.6%;检测出Ca、Fe、K、Na、Mn、Zn矿物质元素6种,其中常量元素Ca含量最高为29.82±0.36 g/kg;果胶、半纤维素、木质素、纤维素含量分别为18.05±0.26 g/100 g,10.6±0.18 g/100 g,17.12±0.32 g/100 g,34.99±0.24 g/100 g.苹果渣中营养物质丰富,特别是膳食纤维含量高,研究结果为苹果渣综合利用,开发功能性食品提供研究基础.The nutritional components of apple residues were discussed to provide basis for the comprehensive utilization of apple residues.The contents of water,ash,fat,protein,starch,dietary fiber,amino acids and minerals of apple residue were determined by drying method,soxhlet extraction method,acid hydrolysis method,kjeldahl method,acetylene flame atomic spectrophotometry and Fan's method.Results indicate:The moisture content of 3.50±0.32 g/100 g,ash 2.49±0.41 g/100 g,fat 7.32±0.23 g/100 g,protein 6.57±0.26 g/100 g,starch 2.37±0.33 g/100 g,dietary fiber 77.40±0.51 g/100 g;17 kinds of amino acids can be determined in the protein,the total content is 6.23×10^(4) mg/kg,among which essential amino acids account for 36.6%of the total amino acids contained;Six kinds of mineral elements were detected,including Ca,Fe,K,Na,Mn and Zn,among which the calcium content of the major element was the highest(29.82±0.36 g/kg);Pectin,hemicellulose,lignin and cellulose content were 18.05±0.26 g/100 g,10.6±0.18 g/100 g,17.12±0.32 g/100 g,34.99±0.24 g/100 g respectively.Apple residues are rich in nutrients,especially dietary fiber.This study provides a research basis for the comprehensive utilization of apple dregs and the development of functional foods.
