摘要
本文对皱纹盘鲍腹足常规营养成分(蛋白质、总糖、脂肪和灰分)和13种金属元素含量进行测定。研究样本为2个年龄段,3个不同品系的南方越冬鲍和北方鲍。常规营养成分和8种有益金属元素(K、Ca、Na、Mg、Cu、Zn、Mn、Se)采用主成分分析法进行降维处理,建立综合分析模型并排序。单因素方差分析结果表明10种不同鲍样本腹足常规营养成分之间差异显著(P<0.05),蛋白质、总糖、脂肪和灰分含量分别为60.80%~72.45%、5.09%~23.88%、1.52%~3.74%和6.27%~7.63%。5种有害金属元素(Pb、Cr、Cd、Hg、As)含量低,符合国家限量标准。有益金属元素含量丰富,其中微量元素Cu、Zn、Mn和Se含量分别为1.57~2.63、2.39~3.59、0.26~0.77和0.031~0.069 mg/100 g。提取3个有效主成分,累积方差贡献率80.742%,综合得分排名前3的为爱莲湾原种鲍1龄北、长岛野生鲍1龄北和生产鲍1龄北。结果说明北方鲍比南方越冬鲍有优势,3个品系中爱莲湾原种鲍处于优势地位,营养价值高。
The general nutritional components(protein,total sugar,fat and ash)and 13 kinds of metal contents in Haliotis discus hannai meat were determined. The samples included 2 age groups and 3 different strains of the overwintering abalones in southern and cultured abalones in northern. The general nutritional components and 8 kinds of beneficial metal element(K,Ca,Na,Mg,Cu,Zn,Mn,Se)were analyzed by the method of principal component analysis. According to the principal component analysis with dimension reduction,the comprehensive analysis model was established and ordered. The results indicated that the nutritional components existed significant differences(P<0.05)among the ten different strains abalone samples. The contents of protein,total sugar,fat and ash were 60.80%~72.45%,5.09%~23.88%,1.52%~3.74% and 6.27%~7.63%,respectively. The content of 5 kinds harmful metal element(Pb,Cr,Cd Hg and As)were low and met the national limited standard. The content of beneficial metal elements were abundant and the content of trace elements Cu,Zn,Mn and Se were 1.57~2.63,2.39~3.59,0.26~0.77 and 0.031~0.069 mg/100 g,respectively. The 3 main components were extracted and their accumulative variance contribution rate reached 80.742%. The top three in the overall scores were the first age northern original abalone of Ailian Bay,the first age northern wild abalone of Changdao and the first age northern production abalone. The results showed that the northern abalones had significant advantages with the overwintering abalones and the Ailian Bay original abalone of the three strains was in a dominant position and had high nutritional value.
