    摘要:

    利用元素分析-同位素比质谱仪(EA-IRMS)、电感耦合等离子体质谱仪(ICP-MS)以及氨基酸自动分析仪测定了13份鱼翅干制品的碳氮同位素比值(δ13C,δ15N)、23种金属元素含量以及17种氨基酸含量。选取包括δ13C值、δ15N值、天冬氨酸、苏氨酸、脯氨酸、亮氨酸、赖氨酸、Mg、Ca、Cr、Mn、Fe、Cu、Zn、Ba在内的15个指标,利用主成份分析法建立了鱼翅干制品品质评价模型,该模型共得到五个大于1的特征值,分别为λ1=3.793、λ2=3.626、λ3=2.290、λ4=1.662、λ5=1.281。因此SPSS只提取了前五个公因子,且前五个因子的方差贡献率84.343%,表明选取的前五个因子已足够描述鱼翅干制品的品质。利用该模型对51种鱼翅干制品的品质进行了评价,结果表明真鱼翅样品的综合得分一般在71.9498~564.9416之间,仿鱼翅样品的综合得分一般在607.9568~644.1284之间,素鱼翅样品的综合得分一般在648.014~798.5972之间。可见,本研究建立的鱼翅干制品品质评价模型可快速、有效的鉴别鱼翅干制品的品质。

    Abstract:

    The δ13C value, δ15N value, and contents of 23 metal elements and 17 amino acids in 13 dried shark fin products were determined by elemental analysis-isotope ratio mass spectrometry (EA-IRMS), inductively coupled plasma-mass spectrometry (ICP-MS) and automatic amino acid analysis. A total of 15 indexes, including δ13C value, δ15N value, aspartic acid (ASP), threonine (THR), proline (PRO), leucine (LEU), lysine (LYS), Mg, Ca, Cr, Mn, Fe, Cu, Zn and Ba, were selected to establish a quality evaluation model for dried shark fin products by the principal component analysis method. For this model, five eigenvalues (λ1 = 3.793, λ2 = 3.626, λ3 = 2.290, λ4 = 1.662, λ5 = 1.281) greater than 1 were obtained. The first five common factors were extracted from SPSS and their variance contribution rate reached 84.343%, indicating the quality of dried shark fin products can be adequately reflected by the selected first five factors. The quality of 51 dried shark fin products was evaluated by the established model. The results showed that the comprehensive scores of genuine dried shark fin samples ranged from 71.9498 to 564.9416, while those of fake and artificial dried shark fins ranged from 607.9568 to 644.1284 and 648.014 to 798.5972, respectively. Therefore, the quality evaluation model established in this study can rapidly and effectively assess the quality of dried shark fin products.
