Patent DE-19834925-A1 (DE)
Inventor: DELL EVA MARCELLO
IPC: A23L25/10
Filed: 1998-08-04
Abstract: The invention relates to a method for the production of a substance, more particularly, a substance that can be used as foodstuff or cosmetic. Said substance is obtained from a first substance that is produced by fine grinding grains or nuts, especially sunflower seeds and by adding a first liquid and salt, sugar or substances similar to salt or sugar. By adding oil, especially sunflower seed oil, or a liquefied fat, a second liquid substance is normally obtained which acquires a more solid consistency by adding a second acid liquid or acidifying agent, especially lemon juice. The amount of the second acid liquid determines the consistency of the first substance. The invention is based on a basic substance for the production of foodstuff and cosmetic products exclusively consisting of a small number of original, natural, genetically unaltered substances that have not been genetically modified -nd that contain no additives or residues from drugs or hormones and ostensibly reduce allergens. The basic substance has optimal value as food stuff and can be used basically as a substitute for dairy products.
