摘要
通过测定干贝在贮藏过程中一系列理化指标的变化,研究了4℃下贮藏时环境相对湿度对干贝品质的影响。考察的指标包括干贝的p H、色泽、挥发性盐基总氮(TVB-N)、过氧化值(POV)和硫代巴比妥酸值(TBARS)等。研究结果表明,在较低相对湿度(RH 23%和43%)下贮藏的干贝,TVB-N值、POV值和TBARS值未发生明显变化。而在较高相对湿度(RH 65%和84%)下贮藏的干贝,TVB-N值、POV值和TBARS值均显著增加,导致品质下降。干贝适宜在较低的环境相对湿度下贮藏。
A series of physical and chemical indexes of dried scallop were studied to investigate the effect of relative humidity(RH) on the quality of dried scallops during storage within 90 days at4 ℃,including water activity(aw),p H,color change,total volatile basic nitrogen(TVB-N),peroxide value(POV),thiobarbituric acid reactive substances(TBARS) and microstructure of the product.The total TVB-N value,POV value,TBARS value of dried scallop stored in a lower relative humidity(RH23% and RH43%) showed insignificant changes during storage,while significantly increased when stored at higher relative humidity(RH65% and RH84%). A lower relative humidity was thus recommended for the storage of dried scallop.
