摘要

本研究利用厨余大豆乳清开发了一种用于保鲜牡蛎的后生物发酵解决方案。植物乳杆菌 299V 能够在 24 小时内于大豆乳清中增殖，无需任何补充。将太平洋牡蛎（Magallana gigas）浸入后益生菌发酵液中，并在 4 °C 下储存 12 天。通过生物累积引入的致病菌副溶血性弧菌和肠炎沙门氏菌在 4 天内被抑制到检测限以下（2 log CFU/g）。与腐败有关的微生物参数和化学参数在 12 天内保持在较低水平。感官评估显示，该产品对大多数参与者（60%）产生了积极影响。总之，本研究报告的后益生菌发酵解决方案以一种可持续的方式提高了牡蛎的货架期和安全性，也可被视为一种创新的益生菌载体，对促进人类健康具有潜在的意义。

Lactiplantibacillus plantarum 299V-fermented soy whey improved the safety and shelf life of Pacific oysters (Magallana gigas)

This study developed a postbiotic fermentation solution for fresh oyster preservation with the use of food waste soy whey. Lactiplantibacillus plantarum 299V was able to proliferate in soy whey within 24 h without any supplementation. Pacific oysters (Magallana gigas) were immersed in the postbiotic fermentation solution and stored at 4 °C for 12 days. Pathogenic bacteria Vibrio parahaemolyticus and Salmonella enterica introduced by bioaccumulation were suppressed to levels below the detection limit (<2 log CFU/g) within 4 days. The spoilage-related microbial parameters and chemical parameters were maintained at low levels across the 12 days. Sensory evaluation revealed that the product had a positive effect on most of the participants (>60%). Overall, the postbiotic fermentation solution reported in this study enhanced the shelf life and safety of oysters in a sustainable way and could also be recognized as an innovative probiotic vehicle with potential implications for human health promotion.
