Definitions
- the invention relates to a method for producing a fiber-based material such as paper, cardboard or cardboard.
- the object of the invention is that the resulting fiber-based material (e.g. paper) releases/releases aromas, nutrients, additives and/or starch upon contact with water (e.g. hydrolysis).
- a fiber-based material e.g. paper
- water e.g. hydrolysis
- the invention further relates to a method for producing such a fiber-based material (e.g. paper). Fiber-based materials of the generic type are not known.
- the paper according to the invention is therefore suitable as filter paper for producing drinks by a filter process, or as a paper cup/plate (e.g. cardboard drinking cup/cardboard food plate,
- Paper drink cups/cardboard food plates, hard paper cups/plates), or drinking vessels made of cardboard can be used to produce drinks or food by filling them with a liquid (e.g. water). Further possible uses in the food sector and/or other areas are conceivable.
- the resulting liquid (drink/water) is changed (e.g. improved) through contact with the fiber-based material (paper), for example through hydrolysis.
- the process for producing such a fiber-based material is characterized in that the fiber material, for example wood pulp, semi-pulp and/or cellulose, which is normally used in paper production and is dissolved in liquid (e.g. water), or is heavily watered down/liquefied, in this process, the production of a functional paper, in addition, this very liquid fiber mixture is brought to the boil above the boiling point.
- Sweeteners e.g. cyclamate, saccharin, thaumatin, fructose
- acidulants such as citric acid
- preservatives such as sorbic acid/potassium sorbate
- the invention is characterized in that the method described under point 5 treats the molecular chains (molecules, rings) of the cellulose fibers (cellulose fibers) of the fiber material used.
- the process opens (splits) the hydrogen bonds between the H and O atoms.
- the sweeteners e.g. cyclamate, saccharin, thaumatin, fructose, etc.
- starch molecules of the sweetener stick to the cellulose molecules or form new compounds.
- the invention is characterized by the fact that new/different molecular chains (molecules, rings) are formed by the process. For example, there are hydrogen bonds between cellulose molecules and starch molecules. These molecular chains (molecules, rings) have the desired reactions/functions, such as flavors, nutrients, additives, or others Starch molecule (molecule chains, rings) based substances are absorbed/enclosed/adhere.
- the invention is characterized in that paper production can be continued in standard operation according to the process described in point 5. This means that the treated pulp, for example wood pulp, semi-pulp and/or cellulose, is normally used at the beginning of paper production.
- the invention is characterized in that in a later process step in the usual paper production, the fiber-based material (e.g.
- molecular chains molecules, rings
- the molecular chains (molecules, rings) have formed new/different connections. For example, there are hydrogen bonds between cellulose molecules and starch molecules. These molecular chains (molecules, rings) have absorbed/enclosed/adhere to the desired reactions/functions, such as flavors, nutrients, additives, or other starch molecule (molecule chains, rings) based substances and release these upon contact with water (e.g. hydrolysis). from/free.
