Abstract
- This work aims at presenting and comparing the antifouling and antibacterial behaviour of three biomimetic surfaces targeting dairy fouling reduction, namely atmospheric plasmasprayed silane-based thin films, lubricated slippery surfaces and femtosecond laser textured lotus-like surfaces. Fouling tests were conducted on a pilot-scale pasteurization plant fed with a model whey protein and calcium foulant solution and tested samples were placed in isothermal holding-like conditions. Detailed characterizations of the substrates before and after fouling test allowed connecting their surface properties to their antifouling performances. The best result was obtained with the nano-rough plasma coatings which led to a substantial fouling reduction for two consecutive pasteurisation runs. These surfaces were subsequently tested towards bacterial adhesion with three different foodborne pathogenic strains, again demonstrating better performances than bare stainless steel.
