Description

  The present invention relates to a cosmetic comprising a composition derived from konjac powder, a method for producing the same, and an oil / water phase separation inhibitor comprising a composition derived from konjac powder.

  Konjac has long been a popular food for general consumers and has been eaten as it is or as a combination with other ingredients. In addition, due to the recent diet boom, konjac is gaining attention as a low-calorie healthy food, and konjac-containing foods containing konjac in various foods have been developed.

  For example, there has been proposed a paste-like material that is finely cut into konjac that has been solidified by adding an alkali so as to be easily mixed with other foods and beverages (Patent Document 1). As another method, it has also been proposed that purified water-soluble konjac mannan obtained by purifying water-soluble konjac mannan contained in konjac flour is mixed with other foods and beverages (Patent Document 2). Furthermore, as another method, it has been proposed that konjac mannan contained in konjac flour is subjected to an enzyme treatment to form a liquid (Patent Document 3). Further, konjac jelly swelled and reacted by adding water and alkali to konjac powder (Patent Document 4), konjac fluid material obtained by performing enzyme treatment after reducing the pH value of konjac jelly (Patent Document 5), high concentration It has also been proposed to add a konjac fluid material (see Patent Document 6) prepared by reducing the pH of an alkaline swelling liquid containing konjac powder and forcibly stirring to a food.

  On the other hand, the use of konjac powder-derived compositions in cosmetics has not been as active as food. For example, foundation cosmetics colored with konjac powder have been proposed as nature-oriented cosmetics (see Patent Document 7). In addition, a cosmetic product to which a konjac extract and a flavor component that suppresses its unique odor is added has also been proposed (see Patent Document 8). Furthermore, a cosmetic product in which a swelling liquid of konjac powder is treated with an enzyme in the presence of a cyclic oligosaccharide and mixed with a cosmetic ingredient has also been proposed (see Patent Document 9). In these and other conventional techniques, the role of the composition derived from konjac powder in cosmetics is limited to ease of coloring, moisture retention, and the like.

  Hereinafter, the present invention will be described in detail. The description of the constituent elements described below may be made based on typical embodiments and specific examples of the present invention, but the present invention is not limited to such embodiments and specific examples. In the present specification, a numerical range represented by using “to” means a range including numerical values described before and after “to” as a lower limit value and an upper limit value.

[Konjac fluid material]
The cosmetic product of the present invention is characterized by being prepared using the konjac fluid material of the present invention. First, the konjac fluid material of the present invention will be described in detail.
The konjac fluid material of the present invention is obtained by performing a step of obtaining an alkali composition by swelling and dissolving konjac powder with water and performing an alkali treatment at pH 9 or higher (hereinafter referred to as “step A”). It is a fluid material that can be prepared by performing a step of reducing pH to less than 8 (hereinafter referred to as “step B”) and has a gelling power. The term “having gelling power” as used herein means that the gelling function is exhibited by heating under alkaline conditions. Ordinary plate konjac has already been gelled, so it does not gel further when heated under alkaline conditions. In addition, a konjac powder that has been swelled with water and then decomposed for a long time with an enzyme or the like to have a low molecular weight is a composition derived from konjac powder, even if heated under alkaline conditions. It will not become. The konjac fluid material of the present invention is manufactured by a specific manufacturing method, and is characterized in that it has both fluidity and gelling power.

  The step of swelling and dissolving konjac powder with water and performing an alkali treatment at pH 9 or more (step A) is a step of partially obtaining the gelling power of konjac powder to obtain an alkaline composition. In the conventional method for producing konjac, the solid konjac is obtained almost completely using the gelling power of konjac powder. However, in step A of the present invention, the use of the gelling power of konjac powder is suppressed. That is, the gelation is kept in a state of being pasty or pasty if water is added and stirred. By suppressing gelation in such a state, it becomes possible to give the konjak fluid material finally obtained a gelling power, and after mixing with other components, the gelling power is exerted. Become moist.

  There are no particular restrictions on the origin or type of konjac powder used in step A. A powdered konjac koji may be used as it is, or a konjac koji powder that has been subjected to a purification process may be used. Moreover, the konjac powder does not necessarily have a uniform particle size.

The alkali added to the konjac powder in the step A is appropriately selected from those that can be used for cosmetics. Konjac powder is normally gelled under an alkali having a pH of 9 or higher. Therefore, the amount of alkali added to the konjac powder in step A is appropriately adjusted so as to be within such a pH range. Preferred is an embodiment in which basic amino acids, basic salts or a mixture of both are added as alkali.
As the basic amino acid, arginine, histidine, lysine, citrulline, ornithine or the like is usually used alone or in combination. Particularly preferred is arginine or lysine. The basic amino acid is preferably added at 1.25 to 20% by weight based on the konjac flour. Basic amino acids have a high pH buffering property. For this reason, when a basic amino acid is used, there is an advantage that a stable pH can be obtained and a composition having a stable quality can be easily provided.

  Basic substances include organic acid salts such as sodium citrate, sodium tartrate, sodium malate, sodium acetate, sodium lactate, sodium succinate, and sodium polyphosphate, sodium pyrophosphate, sodium metaphosphate, phosphoric acid. Phosphate such as disodium, trisodium phosphate, potassium polyphosphate, potassium pyrophosphate, potassium metaphosphate, dipotassium phosphate, tripotassium phosphate, and sodium carbonate, sodium bicarbonate, potassium carbonate, calcium carbonate, carbonate Carbonates such as magnesium, sulfates such as potassium sulfate, sodium sulfate, calcium sulfate and magnesium sulfate, and sodium hydroxide, potassium hydroxide and the like alone or in combination can be used. Thus, any basic salts that can be used in cosmetics can be used as basic salts in the present invention.

  In addition, in order to give a buffer effect, it is also possible to combine each acid or acidic salt, and finally to use it in a combination that makes the pH alkaline. In this case, citric acid, tartaric acid, malic acid, acetic acid, lactic acid, phosphoric acid, monosodium phosphate, monopotassium malate, and the like can be used as the acid and basic salts. The amount used is preferably 0.01 to 20% by weight based on konjac flour.

  If a basic amino acid and a basic salt are used in combination, the functions of both may be well balanced to facilitate production. That is, a basic amino acid has a high pH buffering property, and a stable pH can be obtained, but there is a problem that it is difficult to arbitrarily set a pH value. On the other hand, basic salts have a low pH buffering property, but have an advantage that the pH can be arbitrarily adjusted by selecting a substance. For this reason, if both are combined well, it becomes possible to make the pH setting easy, and to suppress a change in pH due to the raw material and the water used, and to produce a uniform alkaline composition.

  Although pH is adjusted to 9 or more, it is preferable to adjust to 9.0-10.5, and it is more preferable to adjust to 9.3-10.2. If pH is 9.0 or more, it is easy to advance gelation efficiently. Moreover, if pH is 10.5 or less, there exists a tendency which is easy to prevent the bad effect which gelatinization reaction advances too much and water separation and an alkali odor generate | occur | produce.

  The order of adding water and alkali to konjac flour is not particularly limited. For example, water may be added to konjac powder to cause it to swell and dissolve, and then alkali may be added and mixed, or water added with alkali may be added to konjac powder to cause swelling and reaction simultaneously. Alternatively, the konjac powder may be mixed with an alkali and then added with water to swell and dissolve. These methods may be appropriately combined. Alternatively, water containing a basic amino acid may be first added to konjac powder, and then water containing a basic salt may be added. Any method can be adopted as the procedure of step A as long as the swelling with water and the reaction with alkali proceed.

  As a preferred specific example, there can be mentioned a method in which water is first added to konjac powder to swell and dissolve, and a basic amino acid, a basic salt or a mixture of both is added to the obtained konjac paste and mixed well. Another preferred specific example is a method in which a basic amino acid, a basic salt, or a mixture of both is previously mixed and dissolved in water, and the konjac powder is swollen and dissolved in this solution. Another preferred specific example is a method in which basic amino acids, basic salts or a mixture of both are mixed in advance with konjac powder, and then water is added and mixed to swell and dissolve.

  The amount of water added is preferably 10 to 150 parts by weight and more preferably 12 to 100 parts by weight with respect to 1 part by weight of konjac powder.

  After adding water or alkali to konjac flour, it is preferable to react sufficiently at room temperature or under heating. For example, the reaction can be sufficiently carried out by treating at room temperature for 2 to 4 hours and at 60 ° C. for 15 minutes to 1 hour. Conditions such as temperature and time can be appropriately determined depending on the ratio of konjac powder and alkali, addition method, pH, type of cosmetic product used as the final product, and the like. In general, when the pH is high, the reaction time may be short, and when the pH is low, it is preferable to increase the reaction time.

  In step A, components other than those described above may be added as long as the effects of the present invention are not excessively impaired. For example, you may add an emulsifier, starch, fats and oils, a seasoning, a fragrance | flavor, etc. suitably. The type and amount can be determined according to the type and manufacturing conditions of the target cosmetic, the storage environment, and the like. Moreover, you may perform such addition of a component and an additive in a next process (for example, process B, process C, and / or process D).

Next, the process (process B) which reduces the pH of an alkaline composition to less than 8 is demonstrated.
Step B is a step of reducing the pH of the alkaline composition obtained in Step A to less than 8. The pH is usually reduced by adding an acid. The kind of acid to be added is not particularly limited as long as the effect of the present invention is not excessively inhibited. Usually, an organic acid solution such as lactic acid, acetic acid, citric acid, succinic acid, malic acid, tartaric acid or gluconic acid is added. The acid may be added all at once, or may be added continuously or intermittently. The pH is preferably adjusted to 4.6 to 7.5, more preferably 5 to 7. In particular, it is more preferable to control to the target pH without performing treatment that further increases the pH after adjusting to a pH range of less than pH 4.6, particularly less than pH 5.

  The konjac fluid material of the present invention, following Step A and Step B described above, is further subjected to a step of enzyme treatment (Step C) and a step of cutting the agglomerates contained in the enzyme-treated composition (Step D). May be obtained. The konjac fluid material of the present invention may be obtained by performing only step C subsequent to step A and step B.

  In Step C, the enzyme used for the enzyme treatment is preferably one or more enzymes selected from cellulase, hemicellulase, pectinase, protease, and galactomannase. About these enzymes, a commercial item can be used. For example, sucrase N manufactured by Sankyo Co., Ltd. can be preferably used.

  The enzyme treatment is performed at a temperature at which the enzyme can sufficiently act. Usually, it carries out on heating conditions, 40-75 degreeC is preferable and 50-70 degreeC is more preferable. The treatment time varies depending on the type of enzyme and the temperature, but is usually 10 minutes to 12 hours, preferably 20 minutes to 6 hours, and more preferably 30 minutes to 3 hours. Further, stirring is preferably performed during the enzyme treatment.

  After the enzyme treatment, it is preferable to deactivate the enzyme. The means for inactivating the enzyme is not particularly limited as long as the effect of the present invention is not adversely affected. For example, the purpose can be achieved by raising the enzyme to a temperature at which the enzyme is inactivated. When the sucrase N described above is used, the enzyme can be deactivated by raising the temperature to 90 ° C., for example.

Next, step D will be described.
Step D is a step of cutting the agglomerates contained in the enzyme-treated composition obtained in Step C. Although it is possible to obtain a konjac fluid material satisfying the viscosity condition of the present invention by the step C, it is included in the composition obtained in the step C when the viscosity of the composition obtained in the step C is desired to be further reduced. When it is desired to further reduce the agglomerated grains, it is preferable to perform step D. The viscosity can be further reduced by about 0.2 to 1 Pa · s.

  The cutting performed in the process D is preferably performed using a homogenizer or a food cutter. The details of the structure of the food cutter or homogenizer are not particularly limited. When a lump is contained in the enzyme-treated composition obtained in step C, it is only necessary to cut the lump mechanically, and it is preferable to use a high-speed rotary cutter, a high-speed homogenizer, or the like. Such a mechanical cutting process can be repeated a plurality of times. By performing such a cutting process, it is possible to obtain a konjac fluid material that has excellent dispersion characteristics and is easily mixed with other components uniformly.

  In the present invention, a high-concentration konjac fluid material having a konjac powder content of 3.5% by weight or more, a viscosity at 20 ° C. of 4 Pa · s or less and having a gelling power can be preferably used. Such a high-concentration konjac fluid material can be prepared by preparing a high-concentration alkaline composition in Step A and performing forced stirring in Step B. That is, in step A, the amount of water added is preferably 10 to 27 parts by weight, more preferably 11 to 23 parts by weight, and more preferably 12 to 20 parts by weight with respect to 1 part by weight of konjac powder. Is more preferable, and it is especially preferable to set it as 13-18 weight part. Since the composition obtained in step A has a high viscosity, it cannot be sufficiently mixed with other components as it is. For this reason, in step B, the pH of the alkaline composition is reduced to less than 8 and the temperature is increased while forcibly stirring to obtain a forced stirring composition. “Forced stirring” as used herein refers to rotating the stirring means introduced into the alkaline composition at 30 rpm or more, or stirring equivalent to the viscosity of the alkaline composition. Examples of the stirring means include 2 to 12 bladed rotary shafts. While performing such forced stirring, the temperature is gradually raised. The range of the temperature rise is preferably 5 to 60 ° C, more preferably 10 to 55 ° C, and further preferably 20 to 50 ° C. Moreover, it is preferable that the temperature increase rate is initially low and gradually increased. 40 to 75 degreeC is preferable and the final reached temperature in the process B has more preferable 50 to 70 degreeC. In step B, it is preferable to increase the stirring speed as the temperature rises. The stirring speed is preferably finally increased to 1.5 times or more, more preferably 1.8 times or more, and particularly preferably 2 times or more. Specifically, an embodiment in which the rotational speed is increased from 30 rpm to 60 rpm while raising the temperature from room temperature to 60 ° C. can be exemplified as a preferred embodiment. The stirring time is preferably 2 to 45 minutes, more preferably 3 to 30 minutes, and particularly preferably 5 to 20 minutes. After performing Step B, it is preferable to perform Step C, and more preferably to Step D.

  The konjac powder content of the high-concentration konjac fluid material is more preferably 4% by weight or more, more preferably 4.5% by weight or more, and further preferably 5% by weight or more. It is particularly preferable that the amount be at least% by weight. Although there is no restriction | limiting in particular about an upper limit, For example, an 8 weight% konjac fluid material can be obtained. Further, the viscosity at 20 ° C. of the high-concentration konjac fluid material is more preferably 3.5 Pa · s or less, further preferably 3 Pa · s or less, and particularly preferably 2.8 Pa · s or less. . The lower limit is preferably 0.1 Pa · s or more, more preferably 0.2 Pa · s or more, further preferably 0.3 Pa · s or more, and 0.4 Pa · s or more. It is particularly preferred that When specified by the range, the viscosity at 20 ° C. of the high-concentration konjac fluid material is preferably 0.1 to 4 Pa · s, more preferably 0.1 to 3.5 Pa · s, and 0.2 to More preferably, it is 3.2 Pa · s, even more preferably 0.3 to 3 Pa · s, and particularly preferably 0.4 to 2.8 Pa · s.

  The high-concentration konjac fluid material is characterized by low viscosity and gelling power despite containing a large amount of konjac flour. Konjac flour swells with water to form a paste, but the amount of swelling that konjac flour originally has is limited, so a fluid material containing konjac flour in an amount significantly exceeding 3% by weight should be manufactured. Is not easy. In order to obtain a fluid material containing a large amount of konjac powder, a method of decomposing konjac mannan (glucomannan) constituting konjac powder until the swellability is considerably reduced and dissolving or dispersing in water can be considered. Adopting such a method is not preferable because the gelling force and in vivo action of konjac mannan cannot be obtained. According to the above production method, it is possible to increase the concentration while maintaining the gelling power and in vivo action of konjac mannan, so that it is possible to easily produce a konjac fluid material that satisfies the above conditions. it can.
