摘要:

通过光动力疗法(photodynamic therapy,PDT)对牡蛎肉匀浆及牡蛎肠道中的细菌进行杀灭处理,探究PDT可否杀灭牡蛎中的细菌。结果表明,以姜黄素为光敏剂的光动力冷杀菌处理对牡蛎中细菌具有非常好的灭活效果,3、6 h光敏剂富集组对牡蛎的杀菌率可达90%以上。同时该方法处理简便,且具有广谱杀菌特性。

Abstract:

This study aims to explore whether photodynamic therapy (PDT) can inactivate bacteria in oysters. The results
showed that photodynamic inactivation technology using curcumin as the photosensitizer had very good inactivation effect
on bacteria in oysters. This technology has the characteristics of high sterilization efficiency (exceeding 90%), broad antibacterial
spectrum, and easy operation. This study suggests that photodynamic non-thermal sterilization technology has the
potential to be applied in the oyster processing industry in the future.
