Carbon Dioxide as a Solvent and Reaction Medium

Food and flavours Extracts for brewing (hops) Cocoa defatting Spices 

Cosmetics and personal care Natural colours (paprika and turmeric) Defatting cereal and nuts Vegetable oils Ginger (for toothpaste) 

Pharmaceutical products Nuclear waste Black pepper (for mouthwash) Paprika (for lipstick colour) Hempseed, wheatgerm, grape seed (for cream bases) Blackcurrant and borage seeds (for dietary aids) 

As a result of the success of this process and the selectivity that carbon dioxide can enable, related extraction processes have been introduced in a number of areas (Table 10.4), one of the largest being the extraction of hop aroma for the brewing industry.  

Industrially, SCCO2 has been used extensively in polymer processing and synthesis. During the last 10 years, DuPont built a plant that can produce 1000 tonnes of Teflon and other fluoropolymers per year. The polymers produced in this plant are claimed to have superior performance and processing capabilities. Carbon dioxide is seen as the most viable industrial solvent for fluoropolymer synthesis, as hydrocarbon solvents can cause detrimental side
