摘要:

为了解不同养殖产地及野生日本沼虾可食部分矿质元素含量特征,探讨不同产地虾的矿质元素品质及稳定同位素对日本沼虾原产地判别的可能性,选取宜兴、昆山、社渚3处养殖主产地沼虾及长江野生日本沼虾样本为研究对象,分别使用电感耦合等离子质谱仪和稳定同位素比质谱仪对21种矿质元素含量及C、N稳定同位素比等微化学特征进行分析测定。结果显示,各产地虾不仅含有人体必需的常量元素Ca、Na、Mg和K元素,还有人体必需的微量元素Fe、Zn、Mn、Se和Cu。单因素方差分析发现,多种矿质元素含量在春秋两季存在显著差异(P<0.05)。基于Na等12种矿质元素的“指纹”逐步判别分析结果显示,春虾、秋虾的判别准确率分别可以达到100%、98.3%。C、N稳定同位素比“指纹”具有区分野生与养殖日本沼虾的潜力。上述结果表明,日本沼虾富含多种矿质元素,且元素及稳定同位素微化学“指纹”具有产地溯源的应用潜力。

Abstract:

The study aims to understand the content of mineral elements in the edible portion of oriental river prawns (Macrobrachium nipponense) from different cultured and wild origins, to further explore the nutritional quality of oriental river prawns from different origins and the possibilities of mineral elements and stable isotopes for determining the origin of oriental river prawns. This paper selected samples from Yixing, Kunshan, and Shezhu culture origins and the Yangtze River wild oriental river prawns population for the study, and analyzed the content of 21 mineral elements using inductively coupled plasma mass spectrometry (ICP-MS). The results showed that each oriental river prawns contained not only the essential macronutrients Ca, Na, Mg and K, but also the essential trace elements Fe, Zn, Mn, Se and Cu. One-way analysis of variance showed that there were significant differences in the contents of various mineral elements in spring and autumn (P<0.05). The results of stepwise discrimination analysis based on mineral elements showed that the discrimination accuracy could reach 100% and 98.3% for spring and autumn oriental river prawns, respectively, while the C and N stable isotope ratios had the potential to differentiate between wild and farmed oriental river prawns. The results effectively confirmed that the oriental river prawns is a healthy aquatic product with high nutritional value, and that the microchemical ‘fingerprints’ have the potential to be used for origin traceability.
