Process Optimization of Abalone Shucking by High Hydrostatic Pressure Processing and Quality Assessment
摘要
Abstract
We investigated the use of high hydrostatic pressure (HHP)processing for shucking abalone (Haliotis discus hannai Ino )and the changes in physical properties of HHP-shucked abalone.The re-sults show that HHP is a very effective method for abalone shucking.Under the treatments of 200 MPa/1 min and 300 MPa/0 min,the yields of HHP-shucked samples increase by 18% and 16% respec-tively,and the shucking time saves 69% and 72% respectively compared with the manual shucking samples.Moreover,the counts of total aerobic bacteria (TAB)of HHP-shucked abalone reduce signifi-cantly to 270-350 cfu/g from 2.2×10 3 cfu/g.Compared to the control,the moisture of HHP shucking samples significantly increases,however the changes in pH are not obvious.The samples treated by HHP shucking become more light,green and yellow.With the increasing of treatment pressure and time,the hardness of HHP shucking samples shows increase trend,while the springiness decreases. Based on the research results,it indicates that the optimum shucking condition that causes minimal changes in adductor muscle of abalone appearance is 300 MPa/0 min.关键词
