DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a lubricant, and tablets and confections using the same. More specifically, the present invention relates to a lubricant containing a vegetable fat as a main component and not causing capping, sticking, binding and the like at the time of tableting, and to tablets and confections using the same.

[0002]

2. Description of the Related Art In the production of tablets and confectionery, it is necessary to compress powder or powdery raw materials. In tableting, capping of the upper punch side of the tablet peels off thinly in the form of a hat when demolding, sticking that the powder adheres to the punch during tableting and peels off poorly, scratches the tablet surface, and friction between the tablet and the die In some cases, the binding of the tablet may become poor after tableting, and the tablet may not be discharged smoothly.

[0003] Therefore, in tableting, a lubricant is used to improve the fluidity of the raw material powder so that a certain amount is filled in a die of a tableting machine, and at the same time, a tableting machine is used. Prevents capping, sticking, binding, etc. and imparts gloss to the tableting surface. For this purpose, purified talc, magnesium stearate, sucrose fatty acid esters, polyglycerin fatty acid esters, hardened vegetable oils, and the like have been conventionally used as lubricants.

Among them, most of sucrose fatty acid esters are obtained by pulverizing a lump of lumps once and thus are not spherical in shape. And so on. Since polyglycerin fatty acid ester has a small effect, it has to be added in a large amount in order to expect a sufficient effect, and there is a problem that the hardness of the tablet is lowered and the flavor is deteriorated. In the case of magnesium stearate, the effect as a lubricant can be obtained by using a small amount, but its use is limited to pharmaceuticals because it is not recognized as a food additive. The hardened vegetable oil has a small effect as a lubricant and tends to cause blocking in storage in a warehouse or the like in summer. In recent years, relations between serum cholesterol levels of trans fatty acids and cancer have been taken up in Western countries. Further, purified talc is not used much because it has a limited amount of use in foods and has a small effect as a lubricant.

SUMMARY OF THE INVENTION The present invention has been made to solve the problems of the prior art, and provides a lubricant which prevents capping, sticking and binding when compressing tablets and confections. The purpose is to:

[0006]

Means for Solving the Problems As a result of intensive studies to solve the above problems, the present inventor has found that capping, sticking and binding can be achieved by using a vegetable oil powder containing a vegetable oil as a main component. The present inventors have found that tablets and confections that do not wake up can be obtained, and have led to the present invention.
That is, the present invention comprises a lubricant for tablets or tablet confections, comprising a vegetable oil or fat powder obtained by adding protein and sugar to vegetable oil or fat, and adding such a lubricant. A tablet or tablet confection characterized by the above. Preferably, a fine powder having a vegetable oil fat content of 50% by weight or more in the vegetable oil fat powder, blending the vegetable oil with the protein and saccharide, emulsifying and spray-drying the powder, and having an average particle diameter of 250 μm or less. And tablets or tablet confections to which such a lubricant is added.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail.
Vegetable oils and fats according to the present invention are semi-solid at room temperature such as palm oil extracted from copra, palm oil and palm kernel oil extracted from the pulp and fruit kernels of oil palm, and cocoa butter extracted from cocoa seeds. Fats and oils in shape are suitable, but are not limited thereto. In addition, casein soda is suitable as a protein, and lactose and dextrin are suitable as carbohydrates, but are not limited thereto. Food additives such as glycerin fatty acid esters and phosphates may be added as needed.

The vegetable oil powder used in the present invention is used in the form of a fine powder, and its average particle size is preferably 250 μm or less. Particularly preferably, 100 to 150
μm. In other words, the lubricating effect is such that the smaller the particle size, the greater the covering power of the powder particles, as compared with the powder or granules to be lubricated, so that the particle size of the lubricant greatly affects its performance. Here, the average particle diameter refers to a representative diameter of a particle group having two or more kinds of particle diameters, and is determined as a central cumulative value by a specific surface area measurement method.

[0009] Such a vegetable oil and fat powder can be produced by blending a vegetable oil and fat with a protein and a carbohydrate, emulsifying and spray drying. Specifically, protein 8 to 1 to 100 parts by weight of vegetable oil and fat and vegetable oil and fat in an appropriate amount of water.
2 parts by weight, 30 to 40 parts by weight of carbohydrate and, if necessary, the above-mentioned food additive are blended and emulsified, and powdered by spray drying.

The vegetable oil powder of the present invention is mainly composed of vegetable oils and fats, and is used in combination with disintegrants, excipients and absorbents as long as the characteristics and advantages of the vegetable oils and fats are not impaired. can do. For example, calcium phosphate, calcium carbonate and the like can be mentioned. Conventional lubricants such as magnesium stearate, purified talc, sucrose fatty acid ester, polyglycerin fatty acid ester and fumaric acid can also be used in combination.

The manufacturing process of tablets and confectionery is divided into a granulation process for producing powder or granules for compression molding and a tableting process for compression molding. The lubricant according to the present invention is generally used for granulation. Added after process. The addition amount is 0.
The content is 2 to 5% by weight, but the addition amount is not limited depending on the required function. The lubricant used in the present invention can be used in either a direct tablet production method or a wet tablet production method.

EXAMPLES Examples of the present invention will be shown below, but the present invention is not limited only to these. Production Example 1 1.2 kg of lactose, 1.2 kg of dextrin and 0.6 kg of casein soda were added to 4.0 kg of warm water at 60 ° C., and the mixture was stirred for 10 minutes. Next, add 7.0 kg of edible palm oil to 65
The mixture was heated and dissolved at ℃, and gradually added to the aqueous solution to emulsify. The obtained emulsion was spray-dried to prepare a powdered fat. The average particle size of the powdered fat was about 230 μm.

Examples 1-2, Comparative Examples 1-4 Anhydrous crystalline glucose 85% by weight, dextrin 15% by weight
Was granulated, and the lubricants shown in Table 1 were mixed in a predetermined amount with respect to the whole, and the mixture was tableted at a tablet diameter of 5 mm and a tablet pressure of 1200 kgf. The evaluation results are shown in Table 1. In addition, evaluation was performed by visual observation.

Examples 3-4, Comparative Examples 5-8 Reduced maltose 48.5% by weight, reduced lactose 21.4% by weight,
After granulating 12.8% by weight of ascorbic acid, 6.5% by weight of sodium ascorbate, 5.8% by weight of guar gum, and 5.0% by weight of erythritol, the lubricant shown in Table 1 was added to a predetermined amount with respect to the whole. The resulting mixture was tableted at a tablet diameter of 5 mm and a tablet pressure of 1200 kgf. These evaluation results are also shown in Table 2.

[0017]

The vegetable oil and fat powder according to the present invention is extremely safe because it is extracted from natural plant components more than conventional lubricants. In addition, as shown in the evaluation results of Tables 1 and 2, fats and oils are emulsified using proteins and carbohydrates, and a fat and oil powder having excellent storage stability is obtained by spray drying. Hard tablets and confections which do not cause sticking and binding and have good binding properties are obtained.
