Title (EN) ALKALINE PH-MODIFIED EDIBLE CASEIN-BASED FILMS AND COATINGS, AND METHOD FOR THE MAKING THEREOF
(FR) FILMS ET REVÊTEMENTS À BASE DE CASÉINE COMESTIBLE À PH MODIFIÉ ALCALIN ET PROCÉDÉ POUR LEUR FABRICATION
Abstract:
(EN) Improved casein-based films are produced by adjusting the pH of a film-production suspension. The film-production suspension may contain a casein source, a plasticizer, and optionally a strengthening additive. The adjustment of the pH may be accomplished by the addition of an alkaline additive, such as a base, to achieve a desired pH value. The improved casein-based films have improved physical properties as compared to those produced without a pH-adjusted film-production suspension at least in part due to the chemical and structural changes imparted by the change in pH.
(FR) Selon l'invention, des films améliorés à base de caséine sont produits par ajustement du pH d'une suspension de production de film. La suspension de production de film peut contenir une source de caséine, un plastifiant et éventuellement un additif de renforcement. L'ajustement du pH peut être effectué par l'addition d'un additif alcalin, tel qu'une base, pour obtenir une valeur de pH souhaitée. Les films améliorés à base de caséine présentent des propriétés physiques améliorées par rapport à ceux produits sans suspension de production de film à pH ajusté au moins en partie en raison des changements chimiques et structuraux conférés par le changement de pH.
