外文摘要：The effect of modification with transglutaminase (TGase) and 4-hydroxy-3-methoxycinnamic acid (ferulic acid) on properties of tilapia skin gelatin film (TSGF) was researched. The results showed that the peroxide inhibition of modified TSGF increased from 14.7% to 62.0% and 52.1%, when concentrations of TGase and ferulic acid were 0.20 or 1.0 mg.mL(-1). At the same time, the WVP coefficients were lower about 24.2% and 20.6%, respectively. The solubility of TSGF decreased with the increase in concentration of TGase and ferulic acid. As the formation of hydrogen bonds in the structure of the film, the amide A band was shifted towards higher wave numbers after modification.
