Abstract

Abstract Due to their unique biochemical composition, sea cucumbers are highly prized marine echinoderm species. One of their most important properties is that they contain a high amount of collagen in their body wall. In this study, the relationship between collagen and pepsin-solubilized collagen yields from Holothuria tubulosa and Holothuria poli and morphometric and biochemical parameters were investigated. Collagen yields were in the range of 10.63–16.04% for H. tubulosa and 7.12–13.10% for H. poli. It was determined that they may be related to length, body wall weight, and biochemical composition at different length frequencies. Moreover, maturity may have a direct effect on the yield, as mature specimens were found to have lower content of collagen, whereas immature small specimens contained a higher percentage of collagen. It was found that with increasing pepsin concentration, the PSC yield increased to 1.83–1.89% in H. tubulosa and H. poli, respectively. It was determined that collagen from smaller individuals, which contained more moisture and ash, was likely more susceptible to pepsin hydrolyzation. This is the first published study demonstrating that collagen yield of sea cucumbers can vary with length, weight, maturity, and biochemical composition, in addition to species-specific differences.

形态计量学和生化参数对微管Holothuria tubulosa (Gmelin, 1790)和海棠Holothuria (Roweothuria) poli (Delle Chiaje, 1823)胶原和胃蛋白酶溶解胶原产量的影响

摘要海参因其独特的生化成分，是一种珍贵的海洋棘皮动物。它们最重要的特性之一是它们的体壁中含有大量的胶原蛋白。在本研究中，研究了巨管海棠和巨管海棠胶原蛋白和胃蛋白酶溶解胶原蛋白产量与形态计量学和生化参数之间的关系。胶原蛋白产率分别为10.63 ~ 16.04%和7.12 ~ 13.10%。在不同的长度频率下，它们可能与体长、体壁重和生化成分有关。此外，成熟度可能对产量有直接影响，因为成熟的标本胶原蛋白含量较低，而未成熟的小标本胶原蛋白含量较高。结果表明，随着胃蛋白酶浓度的增加，管状芽孢杆菌和波状芽孢杆菌的PSC产率分别提高到1.83 ~ 1.89%。研究确定，体型较小的人的胶原蛋白含有更多的水分和灰分，可能更容易被胃蛋白酶水解。这是首次发表的研究表明，除了物种差异外，海参的胶原蛋白产量还会因长度、重量、成熟度和生化成分而变化。
