PURPOSE: To selectively and efficiently remove cholesterin (ester) from a food by treating the food contg. cholesterin (ester) with compressed CO2 under high pressure to extract the cholesterin (ester), etc., selectively removing the cholesterin (ester) from a flow of gaseous CO2 and circulating the remaining gaseous CO2 . CONSTITUTION: A food contg. cholesterin and/or cholesterin ester is treated with compressed CO2 at 10-90<= under >=100 bar pressure to extract the cholesterin (ester) and other fat-soluble components. Only the cholesterin (ester) is selectively removed from a flow of gaseous CO2 contg. the extracted cholesterin (ester) and fat-soluble components by adsorption on a solid adsorbent or the formation of an adduct. A flow of gaseous CO2 contg. no cholesterin (ester) but contg. other fat-soluble components is led to the top of the treated food or is circulated to a cholesterin extracting process. |
