Description

[Detailed description of the invention]

The present invention relates to chewing gum for tooth cleaning, and more particularly, in a conventional chewing gum composition,
The present invention relates to chewing gum for tooth cleaning, in which part or all of sugars are replaced with cellulose and fats and oils. In the past, chewing gum has been formulated to clean teeth by adding insoluble sodium metaphosphate, an abrasive substance commonly added to toothpaste (Japanese Patent Publication No. 1973-
No. 5840). There are several inventions in which cellulose is blended into chewing gum, such as an invention in which cellulose microcrystalline powder is added to chewing gum to improve its fragrance retention (Japanese Patent Publication No. 41-135), and an invention in which α-cellulose is used as a non-adhesive agent in chewing gum. Added inventions (US Pat. Nos. 4,241,090 and 4,241,091) are known. It is generally believed that chewing gum has a tooth cleaning effect, but as a result of extensive research into the actual state of its effectiveness and methods for improving it, the inventors of the present invention found that even regular chewing gum has a considerable tooth cleaning effect. However, it has been found that the teeth cleaning effect is significantly improved when a large amount of cellulose is added in place of the sugars normally used in chewing gum, and that the tooth cleaning effect is significantly improved by adding a large amount of cellulose by using cellulose and fat together. The present invention was completed based on the discovery that cellulose has the effect of preventing deterioration of the resulting chewing gum texture and improving and enhancing the tooth cleaning effect of cellulose. Accordingly, the general object of the present invention is to provide a chewing gum which has significantly improved tooth cleaning effectiveness than conventional chewing gum. That is, the present invention is a tooth-cleaning chewing gum prepared by substituting part or all of the saccharides with cellulose and oil in a conventional chewing gum formulation. As the cellulose used in this invention, industrially produced wood pulp can be suitably used, but
Other plant celluloses may also be used. The grain size must be 100 mesh or more, which has been crushed by chewing to the extent that it does not feel rough. The amount of cellulose added to chewing gum is 10 to 70
% by weight, preferably 15-40%, optimally 20-30%. If it is less than 10%, there will be no cleaning effect, and if it is more than 70%, the gum will melt and the cellulose will elute, creating a rough texture. Cellulose expands with the liquid during chewing and becomes 4 to 5 times larger as a whole compared to normal gum, and therefore the amount that it wraps around the teeth is also large, and it has been found that this is closely related to improving the teeth cleaning effect. When cellulose alone is added to chewing gum, the cellulose dissolves quickly during chewing, resulting in increased roughness and the tooth cleaning effect is diminished, but this drawback can be improved by using oil in combination. The fats and oils used in this invention are preferably vegetable oils rather than animal fats in terms of stability, and have a low melting point.
Cocoa butter, palm oil, palm kernel oil, and coconut oil at a temperature of 20 to 45°C are suitable, and other materials such as wood wax can also be used.
These may be used alone or in appropriate combination.
The amount of oil and fat used is 2 to 15% by weight based on cellulose.
It is preferably 3 to 10% by weight. The following effects are observed by using oils and fats in combination. (1) Swelling of cellulose due to saliva is sustained appropriately, and elution of cellulose is prevented. (2) Appropriate elasticity is imparted and the chewing gum texture does not sag. (3) Less toothing. (4) The greater the amount of cellulose blended, the more pronounced the effect of preventing cellulose elution by fats and oils. There is a limit to the amount of oil and fat added to chewing gum as a whole, and it is preferably kept at 3% or less. The reasons for this are: (1) The quality of the gum becomes less stable over time. (2) The physical properties become soft and the texture deteriorates. (3) The taste of oil and fat is felt and the taste becomes worse. etc. The chewing gum compounding raw materials other than cellulose and fats and oils may be determined as appropriate according to the formulation for ordinary chewing gum production, and the chewing gum base is manufactured according to the base formulation formulation for ordinary chewing gum,
It is used in the amount found in regular chewing gum. Since some or all of the sugars are replaced with cellulose and fats and oils, the blending amount is completely different from that of ordinary chewing gum. The type of sugar used is the same as the sugar blended in ordinary chewing gum, and is not particularly limited, and can be appropriately selected from these. However, it is best to supplement with strong natural sweeteners or synthetic sweeteners, such as saccharin, saccharin sodium, stevioside, glycyrrhizin salt, etc., to restore the change in the taste of chewing gum by reducing the amount of sugar used and to promote saliva secretion. can be mentioned. Other softeners, moisturizers, flavoring agents, coloring agents, etc. can be added as appropriate. Chewing gum can also be produced in accordance with the production of ordinary chewing gum, and there are no particular limitations on production. Next, the present invention will be specifically explained with reference to Examples. Comparative Example 1 and Examples 2 to 8 Eight types of chewing gum were trial produced according to the formulations shown in Table 1, and various effects were evaluated.

【table】

[Table] In Table 1, the degree of swelling is evaluated as 3 for chewing gum.
After chewing for a minute, the volume ratio of each example is expressed when the chewing gum residue volume of Example 1 without cellulose added is 1. For tooth cleaning, 10 testers were selected, and after rinsing lightly with water after meals, the plaque attached to the front and back of the teeth was stained with fuchsin pigment.
Check the dyeing status and set this status as 100.
After chewing the chewing gum for 3 minutes, check the remaining staining status. If there is no staining at all, it is considered 100% clean. Check the degree of disappearance of the staining area. Average value of 10 people for each chewing gum evaluated on the front and back of the teeth. The values obtained are the cleaning values in Table 1. According to this, in Comparative Example 1 without cellulose, the tooth surface was cleaned by 60%, but the tooth back was cleaned by 20%, which was extremely poor, whereas Example 8
The chewing gum containing 70% cellulose and 3% oil and fat cleansed 95% of the tooth surface and 90% of the tooth back, indicating a significantly improved cleaning effect. It can be seen that the cleaning effect increases in proportion to the addition of cellulose, and that this is also approximately proportional to the degree of swelling. Examples 2 and 3 and 4 and 5 each have the same cellulose content and are examples of the difference between no oil and fat addition, and it can be seen that the oil addition was superior in all evaluations. The texture and flavor were averaged by five chewing gum expert panels, and were rated as ○: good, ○△: somewhat good, △: average, and ×: poor. When the chewing gums of Examples 5 and 6 were evaluated comprehensively, taking into consideration the texture and flavor of the chewing gum and placing emphasis on the tooth cleaning effect, which is the objective of this invention, the chewing gums of Examples 5 and 6 were evaluated as being suitable for practical use. According to the present invention, chewing gum is provided that has a significantly improved tooth cleaning effect compared to conventional chewing gum. Although the preferred embodiments of the present invention have been described above, it goes without saying that various compositional changes can be made without departing from the spirit of the present invention.
