Extraction of natural products using near-critical solvents

Introduction. Food legislation and the scope for increased use of near-critical fluid extraction operations in the food, flavouring and pharmaceutical industries. Other uses for near-critical solvents: chemical reaction and recrystallization. Commercial scale extraction of alpha acids and hop oils with compressed carbon dioxide. Commercial scale decaffeination of coffee and tea using supercritical CO2. Extraction of flavours and fragrances with compressed CO2. Physico-chemical data required for the design of an NCF extraction process. Design and operation of the pressure vessels used in near-critical extraction processes. Pumps and compressors for supercritical extraction. Estimation of separation cost. Index.
