Over the last two decades, there has been an increasing interest in the industrial use of plant proteins for non-food applications because of their renewabiUty or biodegradability Plant proteins ve thus been used for the fabrication of materials such as films and coatings, adhesives, thermoplastics and surfactants. However, for many applications, it is necessary to confer and/or to improve some specific properties by chemical modification of the native proteins. Particularly, the esterification of their carboxyl and amide groups by a fatty alcohol (Fig 1) could lead to a protein-derivative with improved functional properties. Such modification would result into a lower water sensitivity of the protein-based products and it would therefore offer
