Method for producing a functional paper

Abstract

The present invention addresses the problem of producing a fibre-based material such as paper, paperboard or cardboard, for example, which dispenses / releases flavourings, nutrients, additives and / or starch on contact with water (e.g. hydrolysis). Fibre-based materials of the type in question are not known. According to the invention, this problem is solved in that the cellulose fibres used in paper production are subjected to a method (treatment) that opens (splits) the hydrogen bridge-type bonds between the H and O atoms. This method is characterised in that the cellulose (cellulose fibres) is dissolved in liquid (e.g. water) and is brought to boil above the boiling point. Then, sweeteners (e.g. cyclamate, saccharin, thaumatin, fructose) and acidifiers such as citric acid and preservatives such as sorbic acid / potassium sorbate are added. Furthermore, the desired reactions / functions to be released, such as flavourings, nutrients, additives and / or starch, are added to the boiling liquid and the liquid containing the fibrous materials is boiled for a time. Using the conventional paper production method, the liquefied cellulose (cellulose fibres) can then be further processed and dried in the normal manner.

Description

[0001] Process for producing a functional paper

[0002] 1 . The invention relates to a process for producing a fiber-based material such as paper, cardboard or carton.

[0003] 2. The object of the invention is that the resulting fiber-based material (e.g. paper) releases / releases flavors, nutrients, additives and / or starch upon contact with water (e.g. hydrolysis).

[0004] 3. The invention further relates to a method for producing such a fiber-based material (e.g., paper). Fiber-based materials of this generic type are not known.

[0005] 4. Through the manufactured paper (fiber-based material), upon contact with water, for example, hydrolysis, flavors, nutrients, additives, and / or starch can be released as a reaction and cause changes in the water (liquid) that has come into contact. The paper according to the invention is therefore suitable for use as filter paper for the production of beverages by a filtering process, or as paper cups / plates (e.g., cardboard drinking cups / cardboard dinner plates,

[0006] Paper beverage cups / paper dinner plates, paper cups / plates), or drinking vessels made of cardboard, are used for the production of beverages or food by filling them with a liquid (e.g., water). Further applications in the food industry and / or other sectors are conceivable. The resulting liquid (beverage / water) is modified (e.g., improved) through contact with the fiber-based material (paper), for example, through hydrolysis.

[0007] 5. The process for producing such a fiber-based material (e.g., paper) is characterized by the fact that the fiber, for example, mechanical pulp, semi-chemical pulp, and / or cellulose, which is standardly used in paper production and is dissolved in liquid (e.g., water) or highly diluted / liquefied. In this process, the production of a functional paper, this very liquid fiber mixture is further boiled to above boiling point. Sweeteners (e.g., cyclamate, saccharin, thaumatin, fructose), acidulants such as citric acid, and preservatives such as sorbic acid / potassium sorbate are then added. The desired reactions / functions to be released, such as flavors, nutrients, additives, and / or starch, are then added to the boiling liquid, and the liquid with the fiber is boiled for some time (e.g., 5 minutes).

[0008] 6. The invention is characterized in that the process described under point 5 treats the molecular chains (molecules, rings) of the cellulose fibers of the fiber used. This process opens (breaks) the hydrogen bonds between the H and O atoms. The addition of sweeteners (e.g., cyclamate, saccharin, thaumatin, fructose, etc.), which are starch molecules, as well as the other substances described in point 5, and the state of the liquid above the boiling point (boiling state), or after some time upon cooling below the boiling point, allows the starch molecules of the sweetener to adhere to the cellulose molecules or form new bonds.

[0009] 7. The invention is characterized in that new / different molecular chains (molecules, rings) are formed through the process. Thus, for example, hydrogen bonds exist between cellulose molecules and starch molecules. These molecular chains (molecules, rings) have the desired reactions / functions, such as absorbing / enclosing / adhering flavors, nutrients, additives, or other starch molecule (molecular chains, rings)-based substances. The invention is characterized in that paper production can be continued in conventional standard operation after the process described in point 5. This means that the treated fiber, for example mechanical pulp, semi-chemical pulp and / or cellulose, is normally used at the beginning of paper production. The invention is characterized in that the fiber-based material (e.g. paper, cardboard, carton) is dried in a later process step in conventional paper production.At this point in the manufacturing process, a condensation reaction can occur between the molecular chains (molecules, rings). The molecular chains (molecules, rings) have formed new / different bonds. For example, hydrogen bonds exist between cellulose molecules and starch molecules. These molecular chains (molecules, rings) have the desired reactions / functions, such as absorbing / enclosing / adhering flavors, nutrients, additives, or other starch-based substances (molecule chains, rings), and release / release them upon contact with water (e.g., hydrolysis).
