Enzymatic crosslinking
WebAbstract. Different possibilities for protein crosslinking are examined in this review, with special emphasis on enzymatic crosslinking and its impact on food structure. Among potential enzymes for protein crosslinking are transglutaminase (TG) and various oxidative enzymes. Crosslinking enzymes can be applied in cereal, dairy, meat, and fish ... WebThe enzymatic crosslinking resulted in a fast gelation of HA/PEG in 5 min, leading to the formation of an injectable material. In addition, the DA click reaction crosslinking made a hydrogel that has outstanding shape memory and anti-fatigue properties. The storage modulus and breakage strength of the hydrogels were close to 27 kPa and 109.4 ...
