酸性电解水冰对小黄鱼品质及肌肉组织中酶活力变化的影响
Effect of Acidic Electrolyzed Water Ice on Quality and Enzyme Activities in Muscular Tissue of Small Yellow Croaker (Larimichthys polyactis)
摘要
Abstract
Acidic electrolyzed water (AEW) ice has been developed in recent years as a new food preservation technology.To investigate the effect of electrolyzed water ice on preserving the quality of small yellow croaker,changes in enzyme activities and total viable bactefiai counts were assayed periodically during seven days of storage.The results showed that compared with traditional tap water (TW) ice,AEW ice displayed inhibitory activity (P < 0.05) toward cathepsin D and lipase,although it did not present positive effects on inhibiting acid phosphatase and cathepsin B.Conventional plate count enumeration and polymerase chain reaction-denatured gradient gel electrophoresis (PCR-DGGE) indicated that AEW ice had the capability of inhibiting the growth of bacteria on raw fish,and the maximum reduction in bacterial population reached 0.34 (lg(CFU/g)) on the 7th day.Therefore,AEW ice has a broad application prospect and can be more useful than TW ice for preserving seafood.关键词
