摘　　要：为分析和评价青岛紫彩血蛤(Nuttallia olivacea)的营养成分和营养品质,采用化学法和仪器分析法检测了其软体部的基本营养成分,并进行了营养品质评价。结果显示,紫彩血蛤软体部干样中,粗蛋白质、粗脂肪、总糖、灰分的质量分数分别为54.76%、2.60%、5.89%、14.00%;共检测到18种氨基酸,总量为403.6 mg/g(干质量),其中8种必需氨基酸的总量占氨基酸总量的35.63%,非常接近FAO/WHO标准模式中优质蛋白的比例;限制性氨基酸主要为半胱氨酸+蛋氨酸和色氨酸。紫彩血蛤软体部共含有27种脂肪酸,其中单不饱和脂肪酸和多不饱和脂肪酸的总质量分数为53.71%,DHA和EPA占总脂肪酸的22.86%;含有丰富的水溶性维生素B 3(510 mg/kg)和B 2(9.90 mg/kg),并富含钙、铁、锌、硒等多种无机元素;重金属含量符合环境质量评价标准,未检出“六六六”和“滴滴涕”,食用安全性高。结果表明,紫彩血蛤是一种高蛋白、低脂肪、氨基酸含量均衡丰富的水产品,具有较高的开发利用价值和良好的市场前景。To analyze the nutritional composition and quality of the soft body of Nuttallia olivacea in Qingdao,the basic nutritional components of its soft body were tested using chemical and instrumental analysis methods,and a nutritional quality evaluation was conducted.The results showed that in the dry sample of the soft body,the contents of crude protein,crude fat,total sugar,and ash were 54.76%,2.60%,5.89%,and 14.00%,respectively.A total of 18 amino acids were detected,with a total content of 403.6 mg/g(dry weight).Among these,the total content of eight essential amino acids(EAA)accounted for 35.63%of the total amino acid content,closely approaching the proportion of high-quality protein in the FAO/WHO standard model.The limiting amino acids in the soft body of the N.olivacea were mainly cysteine+methionine and tryptophan.The edible part contained 27 fatty acids,with the total content of monounsaturated and polyunsaturated fatty acids accounting for 53.71%,and the content of DHA and EPA accounting for 22.86%of the total fatty acids.It was also rich in water-soluble vitamins B 3(510 mg/kg)and B 2(9.90 mg/kg),and rich in calcium,iron,zinc,selenium,and other inorganic elements.The heavy metal content of N.olivacea met environmental quality assessment standards,and no residues of hexachlorocyclohexane(HCH)or Dichloro-Diphenyl-Trichloroethane(DDT)were detected,indicating high food safety.In conclusion,N.olivacea is a kind of aquatic product with high protein,low fat,balanced,and rich amino acid content,possessing high development and utilization value as well as promising market prospects.
