Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention belongs to the technical field of dentifrice.

[0002]

2. Description of the Related Art Conventionally, dentifrices having various components have been produced from the viewpoint of preventing periodontal disease such as so-called alveolar pyorrhea. Among them, those containing granular salt are known.
For example, Japanese Patent Publication No. 3-2122 discloses that the particle size is 300 μm.
There is disclosed an oral composition (dentifrice) containing 5% by weight or more and less than 10% by weight of a granular salt containing 60% by weight or more of m or more. Also, JP-A-7-206
No. 650 discloses an oral composition containing a granular salt having an average particle size of 150 to 450 μm and a granular baking soda having an average particle size of 45 to 450 μm. These techniques are considered to prevent and treat periodontal disease by absorbing tissue fluid in inflamed gingiva with salt and improving local gingival circulation.

On the other hand, in recent years, a problem that the amount of saliva secreted by modern humans has been reduced has been noted. It is thought that this problem is caused by the fact that the eating of chewed meals has been reduced due to the spread of processed foods. Saliva has an important role in preventing bad breath, periodontal disease and tooth decay by suppressing the growth of microorganisms that live in the oral cavity. Recently, it has been reported that an enzyme called peroxidase contained in saliva is involved in suppressing carcinogens. However, dentifrices containing the above-mentioned salt are insufficient in terms of promoting saliva secretion, so that the amount of saliva secretion can be increased and the oral cavity can be kept more healthy, The development of a new dentifrice has been desired.

[0004] By the way, the fruit of plum is not suitable for eating raw because of its strong acidity. Therefore, various processing methods have been devised since ancient times, and the present invention is still being devised. Umeboshi, which can be said to be a representative of classic processed products, has been deeply penetrated into the diet of our Japanese people as a preserved food that improves fatigue and enhances appetite. Organic acids such as citric acid and malic acid contained have many effects not only to recover fatigue and increase appetite, but also to help absorption of calcium from the intestinal wall and to help energy metabolism of food. Is revealed. Therefore, the production of umeboshi has been increasing as a health food in recent years. By the way, umeboshi is generally produced by salting the harvested ume with salt of 15 to 20% by weight based on the ume, taking out it one to several months later, and drying it for soil. A large amount of by-products called plum vinegar is produced during the production of plum dried vegetables, and the amount of produced by-products tends to increase as the production of plum dried vegetables increases. Some of the plum vinegar is effectively used for ginger pickling, shiso pickling, vinegar pickling, etc., or it is effectively used as plum juice etc. by removing salt by ion exchange membrane electrodialysis. The surplus of plum vinegar is mostly disposed of as industrial waste, and some of it is dumped into rivers, causing river pollution. Therefore, in the production area of plums, how to effectively use the surplus plum vinegar, which becomes industrial waste, has become a major issue.

[0005]

[0014]

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, the present invention will be described in detail.
The dentifrice of the present invention is characterized by containing a plum salt obtained from plum vinegar. Here, the ume vinegar is a so-called ume vinegar, which produces about 20% by weight of raw plum as a by-product when salt is pickled to produce umeboshi, usually using 15-20% by weight of salt with respect to raw plum. It is. The main component of plum vinegar is salt,
Organic acids such as citric acid, malic acid and succinic acid, sugars such as glucose and fructose, serine, aspartic acid,
It consists of amino acids such as methionine and alanine,
In general, the salt concentration of ume vinegar is 15 to 22% by weight, the concentration of citric acid is 3 to 6% by weight, and the concentration of organic acids other than citric acid is 1 to
2% by weight, carbohydrate concentration is about 6 to 10% by weight, and amino acid concentration is about 0.05 to 0.10% by weight.

The method of obtaining plum salt from the plum vinegar is not particularly limited, and can be carried out by appropriately employing general concentration and separation procedures. A specific method includes, for example, a freeze concentration method. This freeze-concentration method generally includes two methods, a suspension crystal method and a forward freezing method, depending on the method of generating ice crystals, and any of these methods can be employed as necessary. The suspension crystal method is a method of growing a large number of ice crystals in a mother liquor, that is, a method of growing ice crystals in a sherbet shape (slurry shape). Although the efficiency is high, there is a problem in separating the ice crystals and the concentrate. On the other hand, the forward freezing method is a method of growing ice crystals of a predetermined thickness from a cooling surface, that is, a method of growing ice crystals in a plate shape (block shape). Solid-liquid separation is easy. The suspension crystal method (sorbet ice method) and the forward freezing method (block ice method) have the above-mentioned advantages and disadvantages, and these two methods may be appropriately used, if necessary, to take advantage of these advantages. Plum vinegar can also be concentrated in combination. As an example of combining both methods,
First, ice crystals are grown in a sherbet form by freezing by a suspension crystal method, and the sherbet-shaped frozen matter is solid-liquid separated by centrifugation, and the separated liquid phase is collected as a first concentrated liquid. The separated solid-phase ice crystals are once melted, and the melt is frozen again by the forward freezing method to grow ice crystals in a block shape, and the frozen product is subjected to solid-liquid separation. An example is a method of recovering as a two-concentrate, and recovering the combined first and second concentrates as one concentrate.

As another means for obtaining plum salt from plum vinegar, a vacuum crystallization method can be employed. The crystallization temperature at that time is inappropriate because the active ingredient such as citric acid is decomposed if it is too high, and the crystallization efficiency decreases if it is too low. Is done. Specifically, crystallization is preferably performed at about 40 to 60 ° C.

The desired plum salt can be separated from the plum vinegar by performing a filtration operation or the like, if necessary, in addition to the various concentrating methods described above. Plum salt is usually 100 plum vinegar
About 10 to 20 parts by weight per part by weight can be obtained.
The components of plum salt are generally 85-95% by weight salt,
2.0-7.0 wt% citric acid, 0.5-1.5 wt% malic acid, 2.0-4.5 wt% potassium chloride,
It is composed of 0.1 to 1.0% by weight of magnesium sulfate (including magnesium chloride), 0.3 to 0.8% by weight of calcium chloride, and the like.

The particle size of the ume salt in the dentifrice is not particularly limited, and the ume salt separated from the ume vinegar can be used as it is. In addition, the particle size of plum salt is 50 ~
When granular plum salt with a large particle size of about 500 μm is used,
Even if a relatively high concentration of plum salt is blended, saltiness is reduced, and the particles are palpable during brushing, so that comfort can be felt.

If the amount of the ume salt is mixed with the dentifrice, the amount is too small to obtain the effect of tightening the gingiva and the effect of promoting the secretion of saliva. The properties and fluidity deteriorate, and the saltiness increases, which is not preferable. Therefore, it is appropriately set in consideration of these balances. Specifically, 5 to 20% by weight based on the total dentifrice
It is preferable that the amount is about the same.
