Description

【0001】
【発明の属する技術分野】
本発明は食品加工の分野に属し、カボス精油の乳化及び均質化の技術分野に関する。
【0002】
【従来の技術とその課題】
食品加工の分野において、親油性物質(カボス精油)と親水性物質を混合することにより、加工品を製造することがあるが、両者の物性上、均一に混合することは容易ではない。
【0003】
従来は、ホモジナイザーによる均質化を行うが、この方法では、多量の親油性物質(カボス精油)を親水性物質に混合した場合、時間の経過とともに分離が起こり、均質化はできない。
また、他に乳化剤を用いる方法もあるが、近年の消費者の健康志向から、従来より用いられているモノグリセライド等の乳化剤の使用には問題が残る。
【0004】
近年では、天然物質由来の乳化剤の使用が多くなってきており、その一つがサイクロデキストリンである。親油性物質(カボス精油)をサイクロデキストリンに包接させる方法として、飽和水溶液法、混練法、乾燥法がある。飽和水溶液法は、サイクロデキストリンの飽和水溶液を調製し、親油性物質(カボス精油)を加え混合すると、包接物が沈殿物として得られる。しかし、安定した包接体を得るためには、さらに水分を除去する必要がある。混練法は、サイクロデキストリンに少量の水を加えてペースト状とし、これに親油性物質(カボス精油)を加えて混練し、含水包接体を作るが、安定した包接体を得るためには、乾燥工程が必要となる。乾燥法は、サイクロデキストリンを水に溶解後、親油性物質(カボス精油)を加えてかく拌し、包接体を形成させる。また、この方法においても、安定した包接体を得るためには噴霧乾燥あるいは凍結乾燥を行う必要がある。以上3つの方法には、共通に乾燥工程が必要となるほど作業が繁雑となり、施設も必要なため経済的にも不利である。
【0005】
【課題を解決するための手段と発明の効果】
本発明者は、上述したような課題を解決するために、あらかじめカボス精油をアルコールと混合した後、これをβ−サイクロデキストリンに混合させることにより、容易に短時間で安定した混合体が得られることを見出した。
上記の方法によると、特殊な機械や設備を利用することなく、また、混合体の水分の除去といった工程を経ることなしに、サイクロデキストリンと親油性物質(カボス精油)を混合させ、安定的な混合体を得ることができる。
本発明は、この混合体を水溶液に溶解させることにより、カボス精油を水溶液中に均一的に分散させる方法である。
【0006】
カボスは独特の香気を持つ香酸柑橘で、その特徴を出すために果皮から抽出した精油を利用するが、油性であるため水溶性のものへ均一に添加、混和するためにはモノグリセライドなど乳化剤を用いる必要がある。しかし食品の分野においては、モノグリセライド等の乳化剤は消費者の健康志向から敬遠される傾向にあり、サイクロデキストリンは澱粉から作られる天然物であるため、消費者の健康志向をかなえるものである。
【0007】
また、用いるサイクロデキストリンについては、α、β、γの三種類で検討した。αおよびγは溶解度は高いが、αはγに比べ内径が小さいため、カボス精油を混合させるためにはより多くのサイクロデキストリンが必要となる。γはα、βに比べ内径が最も大きく、カボス精油を混合させる上で有効であると考えられた。しかし、γは高価なため産業上の利用に際しては有効であるとは言えない。また、α、γは食品へ利用する際、食品添加物としての安全性が保障されていない。そこで、α、γに比べ溶解度は低くいが、熱に対して安定した性質を有し、かつ、食品添加物としての安全性が保障されているβを用いることとした。βは熱に安定であることから、混合したカボス精油を安定的に保持し、香気成分や機能性成分を安定的に水溶性のものへ付与することができる。
【0008】
本方法によれば、特殊な設備や数段階にわたる作業工程を必要とせず、また、天然物で食品添加物としても安全性が保障されたβ−サイクロデキストリンを用いることにより、付加価値の高い加工用素材や加工食品を提供する。また、β−サイクロデキストリンは安価であるため、経済的にも有利である。
【0009】
【発明の実施形態】
カボス精油をβ−サイクロデキストリンに取り込ませる前に、カボス精油とアルコール(99.5%エチルアルコール)を1:1の割合で混合する。アルコールと混合したカボス精油をβ−サイクロデキストリンに添加し、数分間かく拌することにより粉末状のカボス精油混合体が形成される。
【0010】
β−サイクロデキストリンに対するカボス精油の添加割合は、20%まではカボス精油が分離せずに混和する。しかし、かく拌しても湿った状態のままで使いにくく、水溶液等に添加してもすぐに精油が分離してしまう。添加割合を4%まで下げると、湿り気も少なくなり利用しやすくなる。2%では、元のβ−サイクロデキストリンとほぼ同様の粉体となり、より利用しやすい状態となる。このことより、β−サイクロデキストリンに対するカボス精油の添加割合は2〜4%とした。
【0011】
【実施例】カボスアイスクリーム
アイスクリームミックス1リットルに対して、カボス精油が0.05%となるようにカボス精油と混合したサイクロデキストリンを添加、混和する。アイスクリームミックスを作る際に加熱するが、熱によりサイクロデキストリンからカボス精油が放出されるのを避けるために、アイスクリームミックスが冷めてから添加、混和する。

TECHNICAL FIELD OF THE INVENTION
The present invention belongs to the field of food processing and relates to the technical field of emulsification and homogenization of essential oil of Kabos.
[0002]
[Prior art and its problems]
In the field of food processing, sometimes a processed product is produced by mixing a lipophilic substance (kabos essential oil) and a hydrophilic substance, but it is not easy to mix them uniformly due to their physical properties.
[0003]
Conventionally, homogenization is performed using a homogenizer. However, in this method, when a large amount of lipophilic substance (kabos essential oil) is mixed with a hydrophilic substance, separation occurs with the passage of time, and homogenization cannot be performed.
In addition, there is a method using an emulsifier, but there is a problem in using a conventionally used emulsifier such as monoglyceride from the consumer's health consciousness in recent years.
[0004]
In recent years, natural substances-derived emulsifiers have been increasingly used, and one of them is cyclodextrin. As a method of including a lipophilic substance (kabos essential oil) in cyclodextrin, there are a saturated aqueous solution method, a kneading method, and a drying method. In the saturated aqueous solution method, when a saturated aqueous solution of cyclodextrin is prepared, and a lipophilic substance (kabos essential oil) is added and mixed, the clathrate is obtained as a precipitate. However, in order to obtain a stable clathrate, it is necessary to further remove water. In the kneading method, a small amount of water is added to cyclodextrin to form a paste, and a lipophilic substance (kabos essential oil) is added and kneaded to produce a hydrous clathrate. To obtain a stable clathrate, , A drying step is required. In the drying method, after cyclodextrin is dissolved in water, a lipophilic substance (kabos essential oil) is added and stirred to form an inclusion body. Also in this method, it is necessary to perform spray drying or freeze drying in order to obtain a stable clathrate. The above three methods are economically disadvantageous because the work becomes complicated as the drying step is required in common, and facilities are required.
[0005]
Means for Solving the Problems and Effects of the Invention
The present inventor, in order to solve the above-mentioned problems, after preliminarily mixing kabos essential oil with alcohol, and then mixing this with β-cyclodextrin, a stable mixture can be easily obtained in a short time. I found that.
According to the above method, cyclodextrin is mixed with a lipophilic substance (kabos essential oil) without using a special machine or equipment, and without going through a process such as removal of water from the mixture, and is stable. A mixture can be obtained.
The present invention is a method of dissolving this mixture in an aqueous solution to uniformly disperse the essential oil of Cabos in the aqueous solution.
[0006]
Kabos is a citrus citrus fruit with a unique fragrance.To obtain its characteristics, it uses essential oil extracted from the skin.However, because it is oily, it must be uniformly added to water-soluble ones and mixed with an emulsifier such as monoglyceride. Must be used. However, in the field of foods, emulsifiers such as monoglycerides tend to be avoided from the consumer's health consciousness, and cyclodextrin is a natural product made from starch, and thus satisfies the consumer's health consciousness.
[0007]
In addition, cyclodextrins used were examined in three types, α, β, and γ. Although α and γ have high solubility, α has a smaller inner diameter than γ, so that more cyclodextrin is required to mix the essential oil of Kabos. γ has the largest inner diameter compared to α and β, and was considered to be effective in mixing Cabos essential oil. However, γ is expensive and cannot be said to be effective for industrial use. In addition, when α and γ are used for food, safety as a food additive is not guaranteed. Thus, β, which has a lower solubility than α and γ but has properties stable to heat and is guaranteed to be safe as a food additive, is used. Since β is stable to heat, the mixed kabos essential oil can be stably held, and the fragrance component and the functional component can be stably provided to the water-soluble one.
[0008]
According to the present method, no special equipment or several steps of work steps are required, and the use of β-cyclodextrin, which is a natural product and safe as a food additive, provides high added value processing. Provide raw materials and processed foods. Further, β-cyclodextrin is economically advantageous because it is inexpensive.
[0009]
DETAILED DESCRIPTION OF THE INVENTION
Before ingesting kabos essential oil into β-cyclodextrin, kabos essential oil and alcohol (99.5% ethyl alcohol) are mixed at a ratio of 1: 1. Cabos essential oil mixed with alcohol is added to β-cyclodextrin and stirred for several minutes to form a powdered Cabos essential oil mixture.
[0010]
Up to 20% of the kabos essential oil is added to the β-cyclodextrin and the kabos essential oil is mixed without separation. However, even if it is stirred, it is difficult to use it in a wet state, and even if it is added to an aqueous solution or the like, the essential oil is immediately separated. When the addition ratio is reduced to 4%, the wetness is reduced and the use becomes easier. At 2%, the powder becomes almost the same as the original β-cyclodextrin, and becomes more usable. For this reason, the addition ratio of kabos essential oil to β-cyclodextrin was set to 2 to 4%.
[0011]
EXAMPLE 1 Cyclodextrin mixed with Kabos essential oil is added and mixed with 1 liter of Kabos ice cream ice cream mix so that the Kabos essential oil becomes 0.05%. Heat the ice cream mix to make it, but add and mix the ice cream mix after it cools down to avoid release of Cabos essential oil from the cyclodextrin due to heat.
