近红外光谱法快速鉴定干海参产地

该文采用近红外漫反射光谱法，对来自4个不同产地的96个干刺参样品，进行了产地鉴别分析。研究表明：在5 000～4 000 cm-1 波段，干海参样品具有丰富的光谱结构，且反映出了由于海参生长环境不同带来的差异性；对该波段的一次微分光谱数据进行主成分聚类（PCCA）计算，可成功实现对其产地的鉴定分析。该研究为动物性海洋食品的产地快速鉴别分析提供了新方法。

Rapid identification of dried sea cucumber products from different geographical areas by near-infrared spectroscopy

Near infrared spectroscopy (NIR) and principal components class analysis (PCCA) were performed on the classification of dried sea cucumber samples of the same species from four geographical areas. A set of 96 individual dried sea cucumbers (Apostichopus japonicus selenka) were analyzed and successfully differentiated into 4 classes according to the distribution of geographical areas. The result showed that the NIR spectrum (from 5?000 to 4?000 cm-1) indicated the main spectral characteristics of sea cucumbers which were affected by the different growing environmental factors. This study demonstrat that NIR is a convenient tool for fast differentiation of seafoods of animal origin from different geographical areas, such as dried sea cucumber products.
