Description

食品用途に最適な食用油および油脂不溶性物質を含有する食品用カプセルの製造方法に関するものである。カプセル中および食品中での分散適性、保存適性、抗酸化性に優れ、食品の品質改良、栄養強化剤として好適な食品用カプセルの製造方法に関する。   The present invention relates to a method for producing a food capsule containing an edible oil and a fat-insoluble substance that are optimal for food use. The present invention relates to a method for producing a capsule for food that is excellent in dispersion property, storage property, and antioxidant property in capsules and foods, and that is suitable as a food quality improvement and nutrition enhancer.

芯部に食用油を含有するカプセルのうち、比較的大型の食品用カプセル剤としては、特許文献1が知られている。また、同様の形態では、入浴剤などが知られているが、これらの芯部が食用油である場合には、内容物には油溶性物質の混合物もしくは水分を含む乳化状態の混合物が用いられている。油脂不溶性の物質をカプセル中に均一に封入するのは難しく、また、封入できたとしても保存中に沈降して外観を損ない、さらにカプセルを使用する際の内容物の分散性に問題が出る。油脂不溶性物質を均一に充填するための工夫として、蜜蝋、ワックスなどで食用油の粘度を上げる方法も行われているが、保存中の安定性や味質の面で満足できる方法は見いだされていない。
その他、油脂不溶性の物質を食用油に懸濁させてカプセル化するものとしては、医薬品製剤が知られている。医薬品製剤は内容物が少量の極小型のカプセル剤であるが、その場合でも油脂不溶性物質の分散性が課題となっており、その解決方法として特許文献2が知られている。
Among capsules containing edible oil in the core, Patent Document 1 is known as a relatively large food capsule. In the same form, bathing agents are known, but when these cores are edible oils, the contents are a mixture of oil-soluble substances or an emulsified mixture containing moisture. ing. It is difficult to encapsulate oil-insoluble substances uniformly in capsules, and even if encapsulated, they will settle during storage and impair the appearance, and the dispersibility of the contents when using the capsules will be problematic. As a device for uniformly filling fat and oil-insoluble substances, a method of increasing the viscosity of edible oil with beeswax, wax, etc. has been performed, but a method that is satisfactory in terms of stability during storage and taste quality has been found. Absent.
In addition, pharmaceutical preparations are known as those that suspend oil-insoluble substances in edible oil and encapsulate them. The pharmaceutical preparation is a very small capsule with a small amount of contents, but even in that case, dispersibility of the oil-insoluble substance is a problem, and Patent Document 2 is known as a solution.

また、食品に用いる油脂不溶性物質は、様々な機能を有するものがあり、食品の品質改良剤や栄養強化剤、調味料などとして利用されている。一方、食用油も揚げる・炒める等の調理以外にも、各種の食品の風味、作業性の向上などの目的でも使用されている。
食品の調理において、油脂不溶性物質と食用油を同時に用いる場合には、各々を同時に、しかも簡単に分散させることが望まれる。そのため、油脂不溶性物質を予め水に溶いて油脂中に乳化させる方法などが行われているが、乳化状態を安定化する物質の添加が必要であったり、粉末物質の物性が変化してしまうなど、課題は多いのが現状である。
In addition, fat and oil insoluble substances used in foods have various functions, and are used as food quality improvers, nutrition enhancers, seasonings and the like. On the other hand, edible oil is also used for the purpose of improving the flavor and workability of various foods, in addition to cooking such as frying and frying.
In the cooking of foods, when using an oil-insoluble substance and edible oil at the same time, it is desirable to disperse them simultaneously and easily. For this reason, a method of preliminarily dissolving an oil-insoluble substance in water and emulsifying the oil in the oil is performed. However, it is necessary to add a substance that stabilizes the emulsified state, or the physical properties of the powder substance are changed. Currently, there are many issues.

特公平4−52318号公報Japanese Examined Patent Publication No. 4-52318 特開昭62−26216号公報JP-A-62-26216

本発明は、食品の調理時において、油脂不溶性物質と食用油を同時に、簡便に使用でき、その物質および食用油としての機能を維持しながら油脂不溶性物質を良好に分散させることができる食品用カプセルを安定な状態で提供することにある。食品調理のうち、特に米の炊飯において、米飯の風味、食感、保存性など品質、栄養、生理機能などを向上させる油脂不溶性物質と米飯を美味しくする効果のある食用油を、良好な分散性を発揮しながら味質に影響を与えずに簡便に使用できるカプセルを安定な状態で提供することにある。   The present invention provides a food capsule capable of easily and simultaneously using an oil-insoluble substance and an edible oil at the time of cooking food, and capable of favorably dispersing the oil-insoluble substance while maintaining the function as the substance and edible oil Is to provide a stable state. Among food preparations, especially rice cooking, good dispersibility of oil-insoluble substances that improve the quality, nutrition, physiological function, etc. of rice, and cooking oils that have the effect of making rice delicious It is to provide a stable capsule that can be used easily without affecting the taste quality while exhibiting the above.

本発明者らは、食品の調理に有効な成分を含有する水溶性の粉末物質を食用油中に含有させ、かつ、可食性皮膜で被覆したカプセル剤としたものを用いると、簡便性に優れることのみならず、驚くべきことに各々を単独で用いるより格段に分散性に優れることを見いだした。水溶性粉末物質が苦味や酸味などの異味や異臭があるものや吸湿性のあるものの場合にも、食用油中に含有させ、かつ、カプセル剤とすることで、異味や異臭のマスキング効果に優れ、吸湿性の物質でも安定して保存でき、分散性に優れるなど、優れた特性を有することを見いだし、すでに特許出願をしている(特願2003−180867)。
本発明者らは、さらに分散性の改良に関し開発研究をすすめ、比較的大型の食品に用いる芯部に食用油を含有するカプセルにおいて、油脂不溶性物質を配合する際に、均一にカプセル中に充填でき、保存中の安定性がよく、さらに味質に影響を与えない方法を鋭意検討した。その結果、食用油中に高融点の油脂、好ましくは異なる2種類以上の高融点の油脂を配合することにより、上記課題を解決できることを見いだした。
When the present inventors use a capsule containing a water-soluble powder substance containing ingredients effective for cooking food in edible oil and coated with an edible film, it is excellent in convenience. Not only that, but surprisingly, it was found that the dispersibility was much better than when each was used alone. Even when the water-soluble powder material has a bitter or sour taste or a strange odor, or has a hygroscopic property, it can be contained in edible oil and used as a capsule to provide an excellent masking effect on the taste and odor. In addition, it has been found that it has excellent characteristics such as stable storage even in a hygroscopic substance and excellent dispersibility, and a patent application has already been filed (Japanese Patent Application No. 2003-180867).
The present inventors have made further research on improving dispersibility, and in capsules containing edible oil in the core used for relatively large foods, when the oil-insoluble substance is blended, the capsules are uniformly filled. We have intensively studied a method that can be performed, has good stability during storage, and does not affect taste quality. As a result, it has been found that the above problems can be solved by blending high melting point fats and oils, preferably two or more different high melting point fats and oils, in edible oil.

試験区1,3,6は、分散適性、保存適性、炊飯後の味質の何れかが劣る。すなわち、高融点油脂の融点温度を上げれば、油脂不溶性物質の食用油中での分散性、保存適性は向上する。しかし、調理後の味質は風味、舌触り、後味が好ましくない。一方、融点温度を下げれば、調理後の味質は良好であるが、分散適性、保存適性は好ましくない。
試験区7,8も同様、分散適性、保存適性は良好であるが、調理後の味質は好ましくない。
しかしながら、試験区2,4,5では、分散適性・保存適性が良好で、且つ、調理(炊飯)後の味質適性も優れていた。
Test sections 1, 3 and 6 are inferior in dispersibility, storage suitability, and taste after cooking. That is, if the melting point temperature of the high melting point fat is increased, the dispersibility and storage ability of the fat insoluble substance in the edible oil are improved. However, the taste after cooking is unfavorable for flavor, touch and aftertaste. On the other hand, if the melting point temperature is lowered, the taste quality after cooking is good, but dispersibility and storage suitability are not preferable.
Similarly, the test groups 7 and 8 have good dispersibility and storage ability, but the taste after cooking is not preferable.
However, in test sections 2, 4, and 5, the dispersibility and storage suitability were good, and the taste quality suitability after cooking (rice cooking) was also excellent.

食用油として米油〔「オリザサラダ油」オリザ油化(株)製〕を用い、食用油に対して表2に示す配合の高融点油脂を混合して、高融点油脂を完全に溶解させ芯油とした。油脂不溶性物質としてγ−アミノ酪酸〔「GABA協和」協和発酵工業(株)製〕を芯油に対して0.5%添加し15分以上撹拌後、常温まで放冷し、一時間静置後の油脂不溶性物質の分散性を試験例と同様の評価基準で評価した。
保存適性、味質適性の評価についても、試験例と同様の方法でカプセルを製造し、評価した。評価結果は、表2に示す。
実施例1,2は、分散適性、保存適性、味質適性のいずれも良好であった。実施例1も分散適性、保存適性は極めて良好であり、異なる融点の油脂を組み合わせることによって高融点油脂の配合量は少なくても効果があることがわかる。
Rice oil ("Orisa Salad Oil" manufactured by Oriza Oil Co., Ltd.) is used as edible oil, and high melting point fats and oils with the composition shown in Table 2 are mixed with edible oil to completely dissolve the high melting point fats and core oils. It was. Γ-aminobutyric acid (“GABA Kyowa” manufactured by Kyowa Hakko Kogyo Co., Ltd.) is added as a fat-insoluble substance in an amount of 0.5% to the core oil, stirred for 15 minutes or longer, allowed to cool to room temperature, and left for 1 hour. The dispersibility of the oil-insoluble material was evaluated according to the same evaluation criteria as in the test examples.
For evaluation of storage suitability and taste quality suitability, capsules were produced and evaluated in the same manner as in the test examples. The evaluation results are shown in Table 2.
