Abstract:Ginger protease,a novel plant protease belonging to the papain family,has been the subject of fewer in-depth studies compared to other commercial proteases,and its commercial value remains underexplored.Focused on ginger protease,this study reviewed its enzymatic activity assay methods,fundamental enzymatic properties,food applications,enzymatic cleavage sites,hydrolysis effects,as well as the biological activities and digestion/absorption of collagen peptides prepared through its hydrolysis.This offered theoretical support for the commercial application of ginger protease and subsequent research on the biological activities of its hydrolysates.
