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.

Intensification techniques are described for enhancing biocatalytic CO.sub.2 absorption operations, and may include the use of a rotating packed bed, a rotating disc reactor, a zig-zag reactor or other reactors that utilize process intensification. Carbonic anhydrase can be deployed in the high intensity reactor free in solution, immobilized with respect to particles that flow with the liquid, and/or immobilized to internals, such as packing, that are fixed within the high intensity reactor.
