Description
本発明はトランス脂肪酸含量が低いにもかかわらず、部分水素添加油と同等の硬化風味を有する、硬化風味油脂に関する。 The present invention relates to a cured flavor oil and fat having a cured flavor equivalent to that of partially hydrogenated oil, despite having a low trans fatty acid content.
部分水素添加油は、天然の食用油脂を原料として、様々な融点や物性の油脂を得ることができることから、マーガリン・ショートニング等の可塑性油脂用油脂をはじめ、バタークリームやホイップクリーム等のクリーム類、ベーカリー食品などの様々な飲食品に広く使用されてきた。 Partially hydrogenated oils can be obtained from natural edible fats and oils with various melting points and physical properties such as fats and oils for plastic fats such as margarine and shortening, creams such as butter cream and whipped cream, It has been widely used for various foods and beverages such as bakery foods.
しかし近年、この部分水素添加油に含まれるトランス脂肪酸の健康影響が注目され、部分水素添加油を使用せずとも、従来と同様の物性の飲食品を得るための技術開発が盛んに行われている。 However, in recent years, the health effects of trans fatty acids contained in these partially hydrogenated oils have attracted attention, and technology development for obtaining food and drink with the same physical properties as before has been actively conducted without using partially hydrogenated oils. Yes.
しかし、部分水素添加油は硬化風味(水添臭あるいは硬化臭とも言われる)という独特の風味を有するため、部分水素添加油を使用しないで製造されたこれらの飲食品は、部分水素添加油を用いて製造された飲食品に比べてコクのない風味となってしまう問題があった。 However, since partially hydrogenated oil has a unique flavor of hardened flavor (also referred to as hydrogenated odor or hardened odor), these foods and beverages manufactured without using partially hydrogenated oil must have partially hydrogenated oil. There was a problem that it became a rich flavor compared to foods and drinks manufactured using it.
とくにこのコク味の喪失の問題は、油脂の含有量の高いマーガリン・ショートニング等の可塑性油脂、バタークリームやホイップクリーム等のクリーム類、パイ・デニッシュ・ケーキ・クッキー・フライ食品等のベーカリー食品で大きな問題となりつつあり、とくに高温での調理が行われるクッキーやフライ食品などでは、コク味が失われてあっさりした風味になってしまうだけではなく、部分水素添加油を使用した場合に得られた「硬化油風味」といわれる独特の風味がなくなり、さらには油脂の劣化に起因する油臭さを強く感じるようになってしまう。 In particular, the problem of loss of richness is significant in plastic oils and fats such as margarine and shortening with a high fat content, creams such as butter cream and whipped cream, and bakery foods such as pies, Danish, cakes, cookies, and fried foods. It is becoming a problem, especially for cookies and fried foods that are cooked at high temperatures, not only the rich taste is lost and it becomes a light flavor, but also obtained when using partially hydrogenated oil `` The unique flavor called “hardened oil flavor” is lost, and the oily odor due to the deterioration of fats and oils is strongly felt.
このような問題を解決するため、部分水素添加油を使用した場合に特有なコク味を飲食品に付与する目的で、比較的風味の強い油脂を飲食品製造用油脂の一部として利用する方法が検討され、高融点の部分水素添加油を使用する方法(たとえば特許文献1参照)、ラード及び/又は融点が20〜40℃の部分水素添加油を使用する方法(たとえば特許文献2参照)、脱臭条件を穏やかに設定した部分水素添加油を使用する方法(たとえば特許文献3参照)、バニリンを使用する方法(たとえば特許文献4参照)などが開示されている。しかし、これらの方法は、その風味が弱く風味質も異なるため効果が十分ではなく、そのため食用油脂への添加量も多くなってしまう問題や、油脂の風味質や物性に影響が出てしまうという問題があった。 In order to solve such problems, a method of using a relatively strong oil and fat as part of an oil and fat for producing food and drink for the purpose of imparting a special rich taste to the food and drink when using partially hydrogenated oil A method using a partially hydrogenated oil having a high melting point (for example, see Patent Document 1), a method using a lard and / or a partially hydrogenated oil having a melting point of 20 to 40 ° C. (for example, see Patent Document 2), A method using a partially hydrogenated oil in which deodorizing conditions are set gently (see, for example, Patent Document 3), a method using vanillin (see, for example, Patent Document 4), and the like are disclosed. However, these methods are not sufficiently effective because the flavor is weak and the flavor quality is different, so the problem is that the amount added to the edible oil and fat is increased, and the flavor and physical properties of the oil and fat are affected. There was a problem.
一方、酸化した油脂はアルデヒドに由来する強い刺激臭を有するため、バター香料としての使用が行われていた(例えば特許文献5参照)が、この酸化油脂について穏やかな条件で酸化処理した場合に、硬化風味付与剤として利用可能であることが見出され提案されている(たとえば特許文献6参照)。しかし、この方法でも、その風味が弱いため効果が十分ではなく、そのため食用油脂への添加量も多くなってしまう問題があった。 On the other hand, since oxidized fats and oils have a strong irritating odor derived from aldehydes, they were used as butter fragrances (see, for example, Patent Document 5), but when oxidized fats and oils were oxidized under mild conditions, It has been found and used as a cured flavor imparting agent (see, for example, Patent Document 6). However, even in this method, the effect is not sufficient because the flavor is weak, and therefore, there is a problem that the amount added to the edible fat increases.
そのため、少量添加で高い効果を得ることを目的として、酸化処理した油脂から低沸点部分を除去した高沸点部分を使用する方法(たとえば特許文献7参照)や、高リノレン酸の油脂の酸化処理物を使用する方法(たとえば特許文献8参照)が提案された。しかし特許文献7の方法は、蒸留により揮発性の高い不快な風味が除去されるという当然なことを示しただけの一般的なことがらであり、特許文献8の方法は、トランス型ジエンを10%以上含有する特殊な原料油脂を使用する必要があり、一般的ではないという問題があった。 Therefore, for the purpose of obtaining a high effect by adding a small amount, a method using a high-boiling part obtained by removing a low-boiling part from an oxidized fat and oil (see, for example, Patent Document 7), or an oxidized product of a high-linolenic acid fat. There has been proposed a method of using (see, for example, Patent Document 8). However, the method of Patent Document 7 is a general matter that merely shows that the unpleasant flavor with high volatility is removed by distillation. It is necessary to use a special raw material fat containing not less than 5%, and there is a problem that it is not common.
よって、本発明の目的は、トランス脂肪酸含量が低いにもかかわらず、部分水素添加油と同等の硬化風味を有する硬化風味油脂を提供することにある。 Accordingly, an object of the present invention is to provide a cured flavor oil having a cured flavor equivalent to that of partially hydrogenated oil, despite the low trans fatty acid content.
本発明者等は、上記目的を達成すべく種々検討した結果、酸化処理する油脂として、トランス脂肪酸を減らす目的には反するものの、意外にも硬化油を使用することで上記問題を解決しうることを知見した。
