Besides production of extracts and defatted raffinate, technology enables a significant depletion of unwanted ingredients. Associated substances, which could impact downstream process step negatively, are removed by compressed CO₂.
Depletion of xanthines
The origins of the supercritical CO₂ extraction process are based on decaffeination of coffee or tea. In this way decaffeinated tea is suitable for production of drinks for children. In addition to caffeine from coffee or tea, the content of other stimulating xanthines such as theophylline from cocoa can be significantly reduced.
Depletion of colouring agents and odorous substances
Often times lipophilic extracts, made out of leafs or stems, are rich in chlorophyll. By specific selection of parameters and process control, extraction of green colouring agent can be reduced considerably, or chlorophyll can be removed from extracts.
