Abstract
Polyesters, such as those formed using polyols and di- or tri-carboxylic acids or anhydrides or salts thereof, are used as foam control agents in foodstuff processing. The polyesters are biodegradable and biocompatible while still providing excellent foam control capacity. In addition, polyesters foam control agents of the disclosure can be used with various apparatus while avoiding forming films that otherwise affect apparatus function. The polyesters can be used at various stages during industrial processing of vegetables (e.g., potatoes and beets) and fruits.
Claims20
A method for controlling foam while processing a foodstuff, comprising:
- forming a composition comprising a foodstuff and a polyester comprising more than one repeating unit of the Formula I:
- wherein R2 is —(CH2)z—, or
- and
- wherein R1 is:
- wherein R3 comprises one or more of an ester group(s), a hydroxyl group(s), a group corresponding to repeating unit(s) of Formula I, or a combination thereof;
- wherein x and z are, independently, integers in the range of 1 to 8;
- wherein R11 is —H, —OH, or comprises one or more repeating unit(s) of Formula I;
- wherein R12 is —C(O)OH, an anhydride, or a salt thereof, or comprises one or more repeating unit(s) of Formula I;
- and wherein n and m are, independently, integers in the range of 1 to 6;
- and
- processing the composition.
A method for controlling foam while processing a foodstuff, comprising:
- forming a composition comprising a foodstuff and a polyester, wherein the polyester is formed from reactants comprising
- (i) a polyol comprising three or more carbon atoms and two or more hydroxyl groups;
- and
- (ii) a diacid or triacid, or an anhydride or salt thereof, having at least four carbon atoms;
- and
- processing the composition.
