Abstract

Ready-to-eat sea cucumbers (RSC) are highly sensitive to quality deterioration during storage at room temperature. The study investigated the anti-deterioration effects of high-pressure steam sterilization (HPSS) and high-temperature boiling (HTB) on RSC, as well as the impact of secondary bonds on HTB-treated RSC. The results indicated that there were no significant changes in the secondary structure following thermal treatment. Compared to day 0, the maximum thermal denaturation temperature of collagen in the control (CT) group decreased by 24.49℃, while decreases in the HPSS and HTB groups were 8.53℃ and 9.8℃, respectively. This confirmed that the stabilization of RSC could be enhanced through HPSS and HTB treatment during storage. When hydrogen bonds are destroyed, the texture properties of HTB-treated RSC significantly decrease, with hardness values dropping to 3.65±0.514 N and 2.41±0.615 N, springiness to 7.52±1.342 mm and 7.69±0.066 mm, and chewiness to 19.7±1.211 mj and 16.6±1.837 mj, respectively. Furthermore, the degradation of collagen fibers due to the breaking of hydrogen bonds prior to storage was more pronounced. These findings indicate that hydrogen bonds play a crucial role in maintaining the storage stability of RSC. These results offer a theoretical foundation and technical assistance for the processing and storage of RSC.

热处理和二次粘合对即食海参储存稳定性的影响

即食海参（RSC）在室温储藏期间对品质劣变非常敏感。该研究调查了高压蒸汽灭菌（HPSS）和高温煮沸（HTB）对即食海参的防变质效果，以及二级键对高温煮沸处理即食海参的影响。结果表明，热处理后二次结构没有明显变化。与第 0 天相比，对照组（CT）胶原蛋白的最高热变性温度降低了 24.49℃，而 HPSS 组和 HTB 组分别降低了 8.53℃和 9.8℃。这证实了在贮藏过程中通过 HPSS 和 HTB 处理可以增强 RSC 的稳定性。当氢键被破坏时，经 HTB 处理的 RSC 的质构特性会明显降低，硬度值分别降至 3.65±0.514 N 和 2.41±0.615 N，回弹性分别降至 7.52±1.342 mm 和 7.69±0.066 mm，咀嚼性分别降至 19.7±1.211 mj 和 16.6±1.837 mj。此外，储存前氢键断裂导致的胶原纤维降解更为明显。这些研究结果表明，氢键在保持 RSC 储存稳定性方面起着至关重要的作用。这些结果为 RSC 的加工和储存提供了理论基础和技术帮助。

期刊介绍： Process Biochemistry is an application-orientated research journal devoted to reporting advances with originality and novelty, in the science and technology of the processes involving bioactive molecules and living organisms. These processes concern the production of useful metabolites or materials, or the removal of toxic compounds using tools and methods of current biology and engineering. Its main areas of interest include novel bioprocesses and enabling technologies (such as nanobiotechnology, tissue engineering, directed evolution, metabolic engineering, systems biology, and synthetic biology) applicable in food (nutraceutical), healthcare (medical, pharmaceutical, cosmetic), energy (biofuels), environmental, and biorefinery industries and their underlying biological and engineering principles.
