Tyrosinase, laccase, peroxidases, protein-glutamine glutaminase, and peptidoglutaminase all seem promising as far as achieving the intended effect of creating a protein network, namely by virtue of protein cross-linking.
Insofar my research shows that due to current market prices using them for a CPG food item would be cost prohibitive.
As such I am searching for an alternative that is about as costly as transglutaminase.
Warm regards,
