Abstract：Inthisstudy，beef samples processed byfourdiferentcooking methods，namelyultrasonic-asistedvacuum low-temperature cooking （UVLTC），vacuum low-temperature cooking （VLTC），boiling and steaming were evaluated for physicochemical properties，texture characteristics， microstructure and volatile flavor compounds by texture analyzer，scaning electron microscopy （SEM）and gas chromatography-mass spectrometry.The results showed that there were significant diferences in the physicochemical propertiesand texture properties of diferentlycooked bef （P<0.05） .Compared to the other cooking methods， UVLTC significantly decreased theloss rate，protein content， hardness， cohesiveness，elasticity，gumminessandchewinessofbeef，andefectivelyreduced thelossofmoisture.Dierentheating methodshad significantlychanged thestructureof beef muscle;VLTChelpedto maintain thestructureof beef musclefibers， while ultrasonic treatment hada significantdestructive effectonit.Atotalof 42 volatile flavorsubstances were detected， including10aldehydes，9alcohols，8hydrocarbons，6esters，3ketones，2ethers，1acidand3othersubstances.Principal component analysis （PCA），partial leastsquares discriminantanalysis （PLS-DA）and cluster analysis showed significant diferencesinthevolatileflavorcompositionofdiferentlycookedbeef.Atotalof9diffrentialflavorsubstanceswere selected basedonvariable importanceinprojection（VIP）values，whichcouldbeusedaspotentialbiomarkerstodistinguish differently cooked beef samples.
