The invention relates to a physiologically compatible, phospholipid-containing, stable and hard matrix, comprised of a supporting material and of a bioactive constituent, which has an overall diameter ranging from 0.1 to 5000 µm and which contains, as bioactive constituents, = 5 wt. %, with regard to the starting material, of acetone-insoluble phospholipid constituents that, in particular, are phosphatidylserine, phosphatidylcholine and the like, as well as lyso variants and/or derivatives thereof. This matrix together with a preferred supporting material comprised of carbohydrates and/or of proteins and, preferably, of additional bioactive substances provided in the form of ingredients such as amino acids, vitamins, trace elements and the like can have a liquid content and is used, in particular, in functional foods, special foods and food supplements. |
