Description

本発明は、植物精油、油性エキストラクト及びこれらのオレオレジン類、油性の着香料、油溶性天然色素類、脂溶性ビタミン類、動植物油脂類、植物性樹脂類、加工食用油脂から選択される1種または2種以上の可食性油性材料の任意の混合物を乳化して乳化物を調製した後、該乳化物にpH6.0〜9.0シェラック水溶液を添加、混合した混合物を乾燥する徐放性乾燥物の製造方法に関する。 The present invention is selected from plant essential oils, oily extracts and their oleoresins, oily flavorings, oil-soluble natural pigments, fat-soluble vitamins, animal and vegetable oils and fats, vegetable resins and processed edible fats and oils 1 after emulsified mixtures of any of the species or two or more edible oleaginous material to prepare an emulsion, adding a shellac solution of pH6.0~9.0 the dairy product, a controlled release of drying the blended mixture The present invention relates to a method for producing a dry product.

シェラックはセラックとも呼ばれ、マメ科・クワ科の樹木に寄生するラックカイガラムシ(Laccifer lacca KERR.)が樹液を吸い、体外に分泌した通常スチックラックと呼ばれる樹脂状物質より製造される。このスチックラックを粉砕し、篩い分け、水洗し、虫殻、木質、水溶性色素などを除去したものはシードラックと呼ばれ、水溶性色素はラック色素として利用され、シードラックをさらにろ過などを行い精製したものがシェラックである。シェラックは水に不溶の樹脂であるがアルコールに90%程度溶解するほか、アンモニアなどアルカリ水溶液に溶解することが知られている。また、加熱することにより容易に溶融するが一度、熱硬化した場合には熱や溶剤により侵されないという性質がある。硬化した後は光沢があり、耐油性、耐摩擦性を有するため、コーティング剤として医薬品の錠剤、食品であるチョコレート、砂糖製品、カカオ製品、焙焼コーヒー、糖衣菓子、キャンディー、錠菓、ソフトカプセル、果実などのコーティング又は光沢付与剤として利用されている。   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. It is glossy after curing, 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.

通常、シェラックはメチルアルコール、エチルアルコールなどに溶解したアルコール溶液、あるいはアンモニアなどアルカリ水溶液に溶解した形で使用されることがほとんどであり、被コーティング物質である医薬品の錠剤、種々の食品に対し噴霧コーティング、浸漬法、手掛け法、ハケ塗りなどのコーティング方法が用いられている。   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.

これまで被膜剤としてシェラックを用いる数多くのコーティングの提案がある。すなわち、甘味料をシェラックなどの水不溶性、膜生成能を有し、甘味料に適合しうる食用の疎水性物質で被覆化し、カプセル化した遅延放出甘味料組成物(特許文献1参照)、液体又は粉末の生薬エキス類を2〜4倍量のシェラック溶液に分散混合させて乾燥することによるマスキング組成物(特許文献2参照);あるいはシェラックを溶剤などに分散させる際に添加剤を併用し被覆の改善を行う提案である、アルコールなどの溶剤にシェラックを溶かしたコーティング剤に植物油脂、ワックス類、又はその他の脂肪酸エステル類を添加することにより、溶媒成分の除去が進む際に被コーティング物質同士が粘着する現象、いわゆる糸曳きの防止を目的とした提案(特許文献3参照)、シェラックの溶解にアルコールなど有機溶媒に代え、塩基性アミノ酸及び/又は塩基性リン酸塩を使用し、増粘剤及び/又は糖を含有してなる油性菓子の艶付用組成物(特許文献4参照)、シェラックの溶解にアルコール、水酸化ナトリウムおよびアンモニアに代え、塩基性アミノ酸及び/又は塩基性リン酸塩を使用した水性セラック被膜剤の提案(特許文献5参照);あるいは、複数の被膜をすることにより溶解特性を改善する提案として、薬物活性成分をpH依存溶解性放出制御被膜の1種であるシェラックでコーティングし、さらにゲル形成性ポリマーで被覆したカプセル剤(特許文献6参照)、腸内有用細菌を耐酸性および耐水性を有する硬化油又はシェラックでコーティングし、さらに腸溶性の寒天またはゼラチンとペクチンの混合物からなる外皮膜で覆ったカプセルおよびこれを含有するヨーグルト(特許文献7参照);あるいは被担持物質をシェラックなどの透過性物質でコーティングし二酸化ケイ素などの多孔質微粒子に担持させた徐放性多孔質微粒子(特許文献8参照);さらには油をベースとするフレーバー、水、デキストリンなどの多糖類カプセル化物質を噴霧乾燥などでカプセル化し、シェラックによるコーティングを行う提案(特許文献9参照)などがある。しかしながら、これまでの被膜剤としてシェラックの使用はシェラックをアルコール溶液、あるいはアルカリ溶液に溶解して食品、医薬品等の表面に薄い被膜を形成し、該被膜が耐水性、耐酸性を有することを利用して内容物を保護するか、あるいは光沢剤として使用することが目的であり、咀嚼、あるいは周囲のpH変化等により、容易に物理的、化学的に被膜が壊れ、内部の食品の飲食あるいは医薬品の摂取を可能にするものであった。したがって、一度、膜が壊れると短時間のうちに急激に内容成分が外部に流出するために、香気、香味、その他の効果の持続性に欠け、長期間、安定にそれらの効果が持続する徐放性コーティング粉末の開発が望まれていた。   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 powdered 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 aqueous shellac coating agent using basic amino acid and / or basic phosphate instead of sodium and ammonia (see Patent Document 5); or as 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.
