[Analysis and identification of sea cucumber and products]

As high-grade health foods, the deep-processed products of sea cucumber, such as its capsule, injection and etc, have a broad prospect. But so far there is not a generalized efficient verification method or standard for these products. In this research, the authors used Fourier transform infrared spectroscopy (FTIR) and two-dimensional correlation infrared spectroscopy (2D-IR) to determine fine sea cucumber products. At first, by processing live sea cucumber, the authors got some standard spectra. Then the authors used them to compare with different kinds of products, from the correlation coefficient of which the authors found the sea cucumber capsule made by Hai-Yan-Tang Corp. the most correlative with ours. This indicates that the capsule is filled with pure sea cucumber powder and has high quality. The authors' research also implies that the quality-verification for sea cucumber products by using a database of their standard spectra is quite possible.
