However, no dry aloe leaf powder having excellent water dispersibility and excellent dispersibility at 20.0 cm ³ / g or less was known.

[0007] As described above, the conventional dry powder of aloe leaf is only that the aloe leaf is dried under reduced pressure as it is, and the dried pieces are merely powdered by a pulverizer, and the process of crushing the aloe leaf is not carried out in advance. As apparent from the test examples described below, the average particle size and the sedimentation volume were large, and there was a problem that the texture, the skin feel, and the dispersibility were poor.

[0008] As described above, a dried product obtained by freeze-drying a homogenate solution of all leaves of aloe in a vacuum has been known. However, since this dried product is derived from all leaves of aloe, it is regulated by the Japanese Pharmacopoeia. Because it contains medicinal substances such as aloin, which is not suitable for foods and the like, and has not been further pulverized, the average particle size and sedimentation volume are large, as is clear from the test examples described later, There was a problem that skin use feeling and dispersibility were poor.

After drying the product, the crushed product is fractionated into a water-insoluble fraction and a water-soluble fraction, the water-insoluble fraction is washed with water, the water-soluble fraction is deodorized, and the water-insoluble fraction and the water-soluble fraction are separated. By mixing and drying the mixture,
The flavor of the aloe leaf dry powder is further improved, and further, a mixture of the crushed or water-insoluble fraction of the aloe leaf before drying and the water-soluble fraction is selected from the group consisting of proteins, polysaccharides, and sugar alcohols. By adding the selected substances, it was found that the physical properties of the aloe leaf dry powder were further improved, and the present invention was completed.

As the starting material for the method of the present invention, aloe mesophylls obtained by peeling the epidermis from fresh aloe leaves and removing the gel portion can be used. For convenience, commercially available canned aloe mesophyll cans (for example, Tokyo juice) And the like.) Can be used.

The apparatus used for crushing aloe mesophylla of the present invention has a maximum diameter (crushing diameter) of 250 μm.
There is no particular limitation as long as it can be crushed to the following sizes, but a homogenizer (for example, manufactured by Sanmaru Machinery Co., Ltd.), a spike mill (for example, manufactured by Inoue Seisakusho) or the like is used. It is desirable.

In the method of the present invention, the aloe mesophyll is crushed by using the above-mentioned apparatus to crush aloe mesophyll to a maximum diameter (crushing diameter) of 250 μm or less. Specifically, when using a homogenizer,
By appropriately changing the treatment pressure in the range of 5 to 10 MPa, the aloe mesophyll can be crushed to an appropriate size having a maximum diameter (crushing diameter) of 250 μm or less. In this case, in order to prevent the raw material from being heated by frictional heat, it is desirable to carry out the cooling while maintaining the processing temperature below a certain value, for example, 25 ° C.

In the method of the present invention, the apparatus used for drying the crushed aloe leaf is not particularly limited as long as it can dry the crushed aloe leaf. And vacuum dryers (for example,
Made by Yamato Science Co., Ltd. ) Are desirably used, and these dryers are desirably used in appropriate combination.

In the method of the present invention, drying of the crushed aloe leaf is carried out by a known method using the above-mentioned apparatus.

In the method of the present invention, the apparatus used for crushing the dried aloe mesophyll powder has an average particle diameter of 100 μm or less, and 70% or more of the total weight of the dry aloe mesophyll powder within an average particle diameter of ± 30 μm. And settling volume of particles 2
There is no particular limitation as long as it can be adjusted to 0.0 cm ³ / g or less, but it is desirable to use a rotary pin mill (for example, manufactured by Hosokawa Micron Co., Ltd.) or the like as a pulverizer.

In the method of the present invention, the dried product of aloe leaf is pulverized using the above-mentioned apparatus, and the average particle size of the powder is 100 μm or less, and
% Or more of the particles are distributed within the range of an average particle diameter of ± 30 μm, and the sedimentation volume of the particles is adjusted to 20.0 cm ³ / g or less to prepare an aloe leaf dry powder.
Specifically, when a rotary pin mill is used, in order to prevent heating of the raw material due to frictional heat, the disk rotation speed is set to 5,000 to 15,000 rpm while cooling the processing temperature to a certain value or less, for example, 25 ° C. By appropriately changing the range and the processing speed in the range of 50 to 100 kg / hour and pulverizing, the dried aloe mesophyll is converted into a powder having an average particle diameter of 100 μm or less and particles of 70% or more of the total weight. The particles are distributed within a range of an average particle diameter of ± 30 μm, and the sedimentation volume of the particles can be adjusted to 20.0 cm ³ / g or less.

In the first embodiment of the method of the present invention, the apparatus used for fractionating the crushed aloe leaf meat into a water-insoluble fraction and a water-soluble fraction comprises: There is no particular limitation as long as it can be fractionated into a sex fraction, but a centrifuge (eg, manufactured by Tommy Seiko), a centrifugal filtration device (eg, manufactured by Domestic Centrifuge), Kuraray Fire (from Westfalia)
It is desirable to use such as.

In the first embodiment of the method of the present invention, the fractionation of the aloe mesophyllum into the water-insoluble fraction and the water-soluble fraction is carried out by using the above-mentioned apparatus to separate the aloe mesophyllum with the water-insoluble fraction. It is carried out by fractionating into water-soluble fractions. Specifically, when a centrifugal separator is used, the crushed aloe leaf is stored in a centrifuge tube, and the crushed aloe leaf is centrifuged under a condition of a centrifugal acceleration of 1,000 to 10,000 g, whereby a centrifugal residue is obtained. It can be fractionated into a water-insoluble fraction and a water-soluble fraction as a centrifugal supernatant.

In the first embodiment of the method of the present invention, the washing of the water-insoluble fraction of the crushed aloe leaf is carried out by washing the water-insoluble fraction using tap water, distilled water or the like as washing water. You. Specifically, when the above-mentioned centrifugal separator is used, distilled water is added to the centrifugal residue after collecting the water-soluble fraction as the centrifugal supernatant, mixed, and the centrifugal acceleration 10
By repeating the operation of centrifugation under the conditions of 00 to 10000 g, the water-insoluble fraction as the centrifugation residue can be washed with water. The amount of washing water is desirably 50 ml or more per 1 g of the dry weight of the water-insoluble fraction of the crushed aloe leaf meat from the viewpoint of improving the flavor of the aloe leaf dry powder.

In the embodiment 1 of the method of the present invention, the adsorbent used for deodorizing the water-soluble fraction of the crushed aloe mesophyll is:
There is no particular limitation as long as components that adversely affect the flavor of the water-soluble fraction, such as odor components and bitter substances, can be adsorbed and removed from the water-soluble fraction, but activated carbon (for example, Takeda Pharmaceutical Co., Ltd.) It is desirable to use an adsorption resin (manufactured by Hokuetsu Carbon Industry Co., Ltd.).

In the embodiment 1 of the method of the present invention, the deodorization of the water-soluble fraction of the crushed aloe leaf is carried out by deodorizing the water-soluble fraction using the above-mentioned adsorbent alone or in an appropriate combination. You. Specifically, when the adsorption resin is used, the water-soluble fraction of the crushed aloe leaf is subjected to a contact treatment through a column filled with the adsorption resin, and an odor component,
By adsorbing and removing the bitter substance, the water-soluble fraction can be deodorized. The amount (dry weight) of the activated carbon or the adsorption resin used is preferably 20 g or more per 1 g of the dry weight of the water-soluble fraction of the crushed aloe mesophyll from the viewpoint of improving the flavor of the aloe mesophyll dry powder. . If necessary, the deodorized water-soluble fraction may be desalted with an ion exchange resin or the like.

In the first embodiment of the method of the present invention, the mixing of the water-insoluble fraction having been washed and the water-soluble fraction having been deodorized has
Mixing can be performed according to a conventional method. Specifically, a mixture of the water-insoluble fraction and the water-soluble fraction is obtained by adding the deodorized water-soluble fraction to the water-insoluble fraction as the centrifugal residue having been subjected to the water-washing treatment, and mixing.

In the first embodiment of the method of the present invention, the drying of the mixture is carried out by the same method as the drying of the crushed aloe leaf using the apparatus used for drying the crushed aloe leaf.

In the first embodiment of the method of the present invention, it is conceivable to carry out a deodorizing treatment or the like without fractionating the crushed aloe leaf meat into a water-insoluble fraction and a water-soluble fraction.
The water-insoluble fraction is not desirable because it is adsorbed by the adsorbent used in the deodorizing treatment and the recovery rate is reduced.

[0029] In embodiment 2 of the method of the present invention, a substance selected from the group consisting of proteins, polysaccharides, and sugar alcohols to be added to a mixture of a crushed aloe mesophyll or a water-insoluble fraction and the water-soluble fraction. May be any water-soluble, so long as it is acceptable to be added to foods and the like, and can be an auxiliary agent for powdering aloe leaf, specifically, whey protein is used as a protein. (Whey protein isolate)
For example, dextrin and the like as polysaccharides and erythritol and the like as sugar alcohols are particularly desirable.

Further, in embodiment 3 of the method of the present invention, by adding the above-mentioned substance, as apparent from the test examples described later, the total particle size of the particles distributed within the range of the average particle size of the aloe leaf dry powder ± 30 μm is apparent. Weight percentage to weight,
Physical properties such as water retention are further improved. The amount of the substance added is slightly different for each substance, but as is clear from the test examples described later, it is generally 0.5 to 0.5 to the crushed material or the mixture.
3%.

The dry aloe leaf powder produced by the method of the present invention has an average particle diameter of 100 μm or less and particles having an average particle diameter of 70% or more as apparent from the examples described later. Aloe leaf dry powder that is distributed within a diameter of ± 30 μm, has a particle sedimentation volume of 20.0 cm ³ / g or less, has excellent dispersibility, and retains water retention. In addition, the average particle diameter of aloe leaf dry powder ± 30
The weight percentage of the particles distributed in the range of μm with respect to the total weight of the particles means that when the weight percentage is small, the particle size distribution is wide, and contains huge particles and fine particles, and dispersibility and water retention. Therefore, it is desirable that the weight percentage is large, and it is most desirable that the weight percentage be as close as possible to 100%. That is, the upper limit of the weight percentage of the particles distributed in the range of the average particle diameter of the aloe leaf dry powder ± 30 μm to the total weight of the particles is 10%.
0%.

When the average particle diameter of the powder and the sedimentation volume of the particles are small, the dispersibility is improved. However, when the average particle diameter is extremely small, the powder is easily scattered, handling is difficult, and the water retention is particularly deteriorated. The lower limit of the average particle diameter of the powder and the lower limit of the sedimentation volume of the particles are 40 μm and 10.0 cm ³ / g, respectively, as is clear from the test examples described later.

That is, since the aloe leaf dry powder of the present invention has the above-mentioned physical properties, it is excellent in texture and skin feel, excellent in dispersibility, and retains water retention.
It is suitable as a raw material for foods, pharmaceuticals, and cosmetics, particularly as a raw material for packs and the like.

Further, the aloe leaf dry powder produced according to the first aspect of the method of the present invention has a further improved flavor as compared with the aloe leaf dry powder which has not been subjected to the washing and deodorizing treatments. It is suitable as a raw material for food. In addition, the flavor of the aloe leaf dry powder is correlated with the citric acid content, and the citric acid content of the aloe leaf dry powder having a desirable flavor is 6 per 1 g of the aloe leaf dry powder.
mg or less.

According to the first aspect of the method of the present invention, the amount of the washing water in the water washing treatment is 50 ml or more per 1 g of the dry weight of the water-insoluble fraction of the crushed aloe leaf, and
Amount (dry weight) of activated carbon or adsorption resin in deodorization treatment
Is 20 g or more per 1 g of the dry weight of the water-soluble fraction of the crushed aloe leaf, 1 g of dry powder of aloe leaf
It is possible to produce aloe leaf dry powder having a citric acid content of not more than 6 mg per serving. The obtained aloe leaf dry powder has a good flavor and is more suitable as a raw material for food.
