Method for producing foodstuffs and/or feedstuffs by removing undesired lipid constituents using supercritical COsub2/sub and by introducing desired lipophilic substances using compressed COsub2/sub

摘要

The invention relates to a method for producing foodstuffs and/or feedstuffs having improved physiological properties by using dry compressed gases. According to the invention, lipid constituents, in particular, triglycerides and other fat accompanying substances, are removed from the foodstuff matrix by means of extraction involving the use of supercritical CO2 optionally having a proportion of up to 50 wt. % propane. The extracted lipid constituents are then separated out using known methods, and the extracted foodstuff matrix lipophilic constituents, particularly nutrition-physiologically enhancing additives, are homogeneously introduced using compressed CO2 optionally having a proportion of up to 50 wt. % propane. The particular implementation of the method at preferred pressures ranging from 100 to 800 bar and at temperatures ranging from 31 to 100 DEG C enables the specific introduction of, in particular, fat-soluble vitamins, their derivatives or precursors as well as polyunsaturated fatty acids, lipoic acids or sterol derivatives. In this manner, foodstuffs or feedstuffs can be obtained such as cereals with polyunsaturated fatty acids, cacao and egg-yolk products which, in the form of functional foods, take the modified nutritional habits into account.
