海藻糖对草鱼鱼糜冻藏品质的影响
Effects of trehalose on quality of grass carp surimi during frozen storage
摘要
Abstract
This paper conducts a study of the inhibitory effect of trehalose on the protein denaturation of grass carp frozen surimi.At first,salt-soluble protein,total sulfhydryl,Ca2+-ATPase activity and carbonyl group were monitored during the frozen-storage period (12 weeks).When the addition of trehalose was 6%,the inhibitory effect on protein denaturation was the best.Then,the determination of structure characteristics of the group with the addition amount (6%) was conducted after surimi was frozen for six months.Results:the gel strength of the group with best addition amount reached 3 026 g · mm,much higher than the control group (P<0.01).Scanning electron microscope found that ultrafine 3-dimentional network structureof surimi gel was firmer,more compacted and tougher.The trehalose (6%) has an inhibitory effect on the protein denaturation of grass carp frozen surimi,delays the reduction of frozen surimi quality,and has a good application prospect as a potential commercial surimi antifreeze.关键词
