This study developed a postbiotic fermentation solution for fresh oyster preservation using food waste soy whey. *Lactiplantibacillus plantarum* 299V proliferated in soy whey within 24 h. Pacific oysters immersed in the solution and stored at 4 °C for 12 days showed suppressed pathogenic bacteria (*Vibrio parahaemolyticus*, *Salmonella enterica*) below detection limits (<2 log CFU/g) within 4 days. Spoilage-related parameters remained low, and sensory evaluation showed positive effects. This sustainable approach enhanced oyster shelf life and safety, also serving as a novel probiotic delivery vehicle.
