Description

  The present invention relates to a sustained-release dried product obtained by drying a mixture of a substance to be dispersed and powdered shellac together with a shellac ethanol solution.

  Shellac is also called shellac, and is produced from a resinous substance called stick lac, which is secreted outside the body by sucking sap by Laccifer laquer KERR. Parasitic on leguminous and mulberry trees. This stick rack is crushed, sieved, washed with water, insect husks, wood, water-soluble pigments, etc. removed are called seed racks, and water-soluble pigments are used as rack pigments. Shellac is what has been refined. Shellac is a resin that is insoluble in water, but it is known that it dissolves in about 90% of alcohol and also in an aqueous alkali solution such as ammonia. Moreover, although it melts easily by heating, once it is thermally cured, it has the property of not being attacked by heat or a solvent. After curing, it has gloss, oil resistance, and friction resistance, so it is a pharmaceutical tablet as a coating agent, food chocolate, sugar products, cacao products, roasted coffee, sugar-coated confectionery, candy, tablet confectionery, soft capsule, It is used as a coating for fruits and glossing agents.

  Normally, shellac is mostly used in the form of an alcohol solution dissolved in methyl alcohol, ethyl alcohol or the like, or dissolved in an alkaline aqueous solution such as ammonia. Coating methods such as coating, dipping, handling, and brushing are used.

  There have been many proposals for coatings using shellac as a coating agent. That is, a delayed release sweetener composition in which a sweetener is coated with an edible hydrophobic substance having a water-insoluble and film-forming ability such as shellac and compatible with the sweetener (see Patent Document 1), liquid Alternatively, a masking composition obtained by dispersing and mixing powdery herbal extracts in 2-4 times amount of shellac solution and drying (see Patent Document 2); or coating with additives when dispersing shellac in a solvent or the like When the removal of solvent components proceeds by adding vegetable oils, waxes, or other fatty acid esters to a coating agent in which shellac is dissolved in a solvent such as alcohol. A proposal for the purpose of preventing the phenomenon of sticking, so-called stringing (see Patent Document 3), replacing shellac with an organic solvent such as alcohol, Composition for glazing oily confectionery using basic amino acid and / or basic phosphate and containing thickener and / or sugar (see Patent Document 4), alcohol, hydroxylation for dissolution of shellac Proposal of an aqueous shellac coating agent using basic amino acid and / or basic phosphate instead of sodium and ammonia (see Patent Document 5); or a proposal to improve the dissolution characteristics by forming a plurality of coatings, Capsules coated with shellac, which is a kind of pH-dependent soluble controlled release coating, and coated with a gel-forming polymer (see Patent Document 6), acid-proof and water-resistant for enteric useful bacteria Capsules coated with hardened oil or shellac and further covered with an enteric agar or an outer skin consisting of a mixture of gelatin and pectin and the like Yogurt (see Patent Document 7); or sustained release porous fine particles (see Patent Document 8) in which a supported material is coated with a permeable material such as shellac and supported on porous fine particles such as silicon dioxide (see Patent Document 8); There is a proposal of encapsulating polysaccharide-encapsulated substances such as flavors based on, water and dextrin by spray drying and the like and coating with shellac (see Patent Document 9). However, the conventional use of shellac as a coating agent utilizes the fact that shellac is dissolved in an alcohol solution or an alkaline solution to form a thin film on the surface of food, medicine, etc., and the film has water resistance and acid resistance. It is intended to protect the contents, or to be used as a brightening agent, and the film is easily and physically broken by chewing or changing the pH of the surroundings. The intake was possible. Therefore, once the membrane is broken, the content components suddenly flow out to the outside in a short period of time, so the aroma, flavor, and other effects are lacking in sustainability, and those effects are sustained over a long period of time. The development of releasable coating powder has been desired.
