Abstract：Thisstudy investigated the effectsof different durations （5，1O，15，20，and 25min ）ofhighvoltageelectrostatic field （HVEF）treatment onthe microstructure，intermolecular interactions，protein secondary structure，pH，shear force， whitenes，texturalproperties，water-oldingcapacity，moisturecontent，andwaterdistributiontc.infreshhaelcafish muscle.The results showed that compared to the control group，the 5-，1O-，15-，and 20-min treatment groups exhibiteda moreordered arangementof muscle fibers with no significant changes ingaps betweenmuscle fibers.HVEF treatment significantly reduced the content of ionic bonds （P<0.05） ，but had no significant effects on hydrogen bonds，hydrophobic interactions，orproteinsecondarystructure.AfterHVEFtreatment，nosignificant changes wereobserved inthemoisture content，whitenes，ortexturalpropertiesofthefishmuscle.Inthe2O-mintreatmentgroup，thetransverserelaxationtimeof immobilewater （T22） shortened，and the relative content of free water （P23） decreased to 1.60% .Relative to the other treatment groups，the 25-min treatment group showed increased gaps between muscle fibers，along with reduced moisture content and shear force. Overall，HVEF treatment for 20min had no significant impact on muscle quality or water distribution in channelcatfishfillets.

斑点叉尾（Ictaluruspunctatus）作为全球最重要的淡水养殖品种鱼之一，自1984年由湖北省水产科学研究所从美国加利福尼亚州引入我国后，已成为我国具显著经济价值的特色淡水渔业资源。（剩余18751字）
