Abstract
Ion exchange methods applied to lactose recovery offer promise of better yields. Aqueous saline and solvent extraction methods (methanol, ethanol) for lactose recovery show promise and deserve pilot plant development. They lead to recovery of valuable by-product milk protein in good condition. Penicillin requirements led to greatly increased lactose production and utilization (3-fold increase) during the period from 1943 thru 1952. Hydrolyzed lactose products were developed for food and feed use. The use of finely divided lactose to control coarse crystallization in dairy products was extended. Lactose derivatives made by fermentation (alcohol, vinegar, lactates, acetone, butanol, riboflavin) became of some economic importance. Production of lactobionates from lactose by an electrochemical method was developed. Lactose in the form of whey products continued to be used in very large tonnage by the feed industry. 43 Refs. through 1953.
