The 2011–2016 reports from the Food and Agriculture Organization of the United Nations has stated that annual food loss and waste occurs on a massive scale in fisheries and aquaculture. This study aimed to explore advanced technologies to recycle wasted salmon as an industrial resource with high commercial value by applying enzymatic hydrolysis under HPCD. Our results showed that HPCD treatment at 50 °C and 1 MPa for 16 h effectively prevents salmon from microbial contamination. Real-time PCR analysis demonstrated that HPCD was also able to inhibit an increase in bacteria at moderate temperatures. Based on NGS analysis, there was a very low abundance of Bacillus and some histamine producers, such as Pseudomonas, Acinetobacter, Enterobacter, and Klebsiella, detected in samples treated using HPCD at 50 °C and 1 MPa for 16 h. Hydrolysate analysis showed that HPCD treatment at 1 MPa did not affect the hydrolysates from salmon. It is anticipated that the results from this study will support the application of HPCD in industrial enzymatic hydrolysis and increase the sustainability of bio-based materials.

联合国粮食及农业组织2011-2016年报告指出，每年的粮食损失和浪费在渔业和水产养殖中大规模发生。这项研究旨在探索先进技术，通过在HPCD下应用酶水解，将浪费的鲑鱼作为具有高商业价值的工业资源进行回收。我们的结果表明，在50°C和1 MPa的压力下进行HPCD处理16小时可有效防止鲑鱼受到微生物污染。实时PCR分析表明，HPCD还能够在中等温度下抑制细菌的增加。根据NGS分析，芽孢杆菌和一些组胺产生剂的含量非常低，例如假单胞菌，不动杆菌，肠杆菌和克雷伯菌，在使用HPCD在50°C和1 MPa下处理16小时的样品中检测到。水解产物分析表明，在1 MPa下进行HPCD处理不会影响鲑鱼的水解产物。可以预期，这项研究的结果将支持HPCD在工业酶水解中的应用，并增加生物基材料的可持续性。
