Abstract: Adipose tissue plays a crucial role in energy storage，endocrine regulation，and meat quality determination． With the rapid advancement of proteomic technologies， analyzing the biological functions， developmental dynamics，and meat quality -related traits of porcine adipose tissue at the proteome level has become a research focus．This paper systematically reviews recent progress in proteomic studies of porcine adipose tissue , with emphasis on the application of various technological platforms，the dynamic protein networks underlying adipose development and deposition，and the identification of key regulatory proteins influencing meat quality traits． Furthermore，future research trends are outlined to provide new theoretical foundations and targets for molecular breeding and meat quality improvement in pigs．
