Coating that sticks through frying, freezing and the supply chain
Producers of plant-based chicken nuggets, fish fingers and breaded meat alternatives face a coating challenge that conventional binders cannot solve cleanly. Egg white and wheat flour provide adhesion, but they introduce allergens and prevent clean-label positioning.
Producers of plant-based chicken nuggets, fish fingers and breaded meat alternatives face a coating challenge that conventional binders cannot solve cleanly. Egg white and wheat flour provide adhesion, but they introduce allergens and prevent clean-label positioning. When the coating separates from the substrate during frying, the consequences go beyond consumer disappointment because loose coating causes oil fouling, which affects food safety, fire safety and production cost. A cleaner solution that holds through pre-dusting, batter application, frying and freeze-thaw cycles prevents all these problems.
A direct replacement for wheat flour pre-dust
PerfectaSOL®, a native potato protein isolate, was tested as a direct replacement for wheat flour pre-dust across plant-based substrates including TVP, mycoprotein, shrimp, fish and chicken. Its thermo-irreversible gelation mechanism forms a permanent bond upon heating and delivers exceptional coating adhesion scores both before and after frying, significantly outperforming the wheat flour reference. Pre-dust pick-up was substantially lower than wheat flour, reducing ingredient use, while breading pick-up remained comparable, maintaining the crispy coating consumers expect. Fat uptake and moisture loss during frying were both meaningfully reduced, resulting in a juicier product with lower fat content.
