【産業上の利用分野】
本発明は、新規な風味増強組成物、該風味増強組成物を含有する食品または調味料、および食品の風味増強方法に関する。さらに詳細には、L−グルタミン酸アンモニウムを含有する風味増強組成物、該風味増強組成物を含有する食品または調味料、およびL−グルタミン酸アンモニウムを含有する風味増強組成物を添加して、旨味、塩味、および/またはコク・濃厚感を増強することを特徴とする食品の風味増強方法に関する。
【0002】
【従来の技術】
近年、ライフスタイルの変化によって、加工食品が多く食されるようになり、食品の味、外観、食感等の性質を調整するために食品添加物の意義がますます高まっている。特に、食生活の多様化によって、多種多様な調味料や風味増強剤が求められている。
【0003】
魚介系の風味増強の方法としては、例えば、魚醤と醤油を調合又は調熱する方法(特許文献1)、醤油及び/又はだしを含有する調味液に含硫化合物を添加し加熱する方法(特許文献2)が知られている。しかし、いずれも複数の成分の混合、加熱すること、組成が複雑である天然物由来の原料の使用などが必要であるという問題があった。そのため、添加するだけで水産物関係の風味増強の効果が見られるような簡便な風味増強剤が望まれていた。
【0004】
一方、調味料として使用される食品添加物の1つにL−グルタミン酸塩があるが、一般的にL−グルタミン酸塩は、ナトリウム塩を始めとして、旨みを付与する物質として公知である。このようなL−グルタミン酸塩の中で、L−グルタミン酸アンモニウムは、単独では旨味、苦味を有する物質であるが、旨みを付与する以外の機能、例えば、食品の風味増強効果については何ら知られてはいなかった。
【0005】
例えば、特許文献3は、グルタミン酸ナトリウム等の周知の調味料の代替品として、ナトリウム塩以外のグルタミン酸塩、5’−リボヌクレオタイド、有機酸、有機酸塩等を含有する調味料または調味食品を開示している。ここではグルタミン酸塩の一例として、グルタミン酸アンモニウムが記載されている。また、特許文献4は、昆布の風味を持たずに天然昆布だしの呈味を十分有する調味食品として、カリウム、グルタミン酸(塩)、糖アルコールの3成分を特定の比率で含有する食品を開示している。この食品は、呈味質において複雑で口腔に広がる呈味の幅、コクがあり、嗜好性に富むものであったが、ここでもグルタミン酸塩の一例として、グルタミン酸アンモニウムが記載されている。しかし、これらのグルタミン酸アンモニウムの記載は、あくまでグルタミン酸塩の一種として例示されているのに過ぎず、L−グルタミン酸アンモニウムが有する風味増強効果については教示も示唆もされていなかった。

[Prior art]
In recent years, due to lifestyle changes, processed foods have been eaten a lot, and the significance of food additives is increasing in order to adjust the properties of food such as taste, appearance and texture. In particular, a wide variety of seasonings and flavor enhancers are required due to diversification of eating habits.
[0003]
As a method for enhancing the flavor of seafood, for example, a method in which fish soy and soy sauce are prepared or heated (Patent Document 1), a method in which a sulfur-containing compound is added to a seasoning liquid containing soy sauce and / or dashi and heated ( Patent document 2) is known. However, there are problems in that it is necessary to mix and heat a plurality of components and to use raw materials derived from natural products having a complicated composition. Therefore, there has been a demand for a simple flavor enhancer in which the effect of enhancing the flavor related to fishery products can be seen only by adding.
[0004]
On the other hand, L-glutamate is one of food additives used as a seasoning. Generally, L-glutamate is known as a substance that imparts umami, such as sodium salt. Among such L-glutamate salts, ammonium L-glutamate is a substance having umami and bitterness alone, but it is not known at all about functions other than imparting umami, for example, a flavor enhancing effect of food. I didn't.
[0005]
For example, Patent Document 3 discloses a seasoning or a seasoning food containing glutamate other than sodium salt, 5′-ribonucleotide, organic acid, organic acid salt, or the like as a substitute for a known seasoning such as sodium glutamate. Disclosure. Here, ammonium glutamate is described as an example of glutamate. Patent Document 4 discloses a food containing three components of potassium, glutamic acid (salt), and sugar alcohol in a specific ratio as a seasoned food that does not have the taste of kombu but has a sufficient taste of natural kombu dashi. ing. This food has a complex taste and a wide breadth of taste that spreads to the oral cavity and is rich in palatability. However, ammonium glutamate is also described here as an example of glutamate. However, these descriptions of ammonium glutamate are merely exemplified as a kind of glutamate, and the flavor enhancement effect of ammonium L-glutamate has not been taught or suggested.

As shown in Table 3, in both the skipjack extract and the scallop extract, more than half of the panelists gave evaluation that the umami, richness and richness were enhanced by the addition of ammonium L-glutamate. On the other hand, ammonium glutamate contributed little to bitterness or acidity, and it was evaluated that about 10 to 40% of panelists had an effect on sweetness and saltiness. From this, the effect of the addition of ammonium L-glutamate on the seafood extract is mainly in the enhancement of umami, richness and richness .
[0027]
Example 2: Effect of ammonium L-glutamate on vegetable extracts The effects of adding 0.01% and 0.05% ammonium L-glutamate on the kombu extract, shiitake extract, cabbage extract, and radish extract (Table 1) were examined. The results are shown in Table 4 . As an evaluation method, 1% aqueous solution of each of the above vegetable extracts was used as a blank, and samples were prepared by adding 0.01% and 0.05% ammonium L-glutamate to each 1% aqueous solution. A panel of 14 well-trained panelists performed a sensory evaluation on whether the sweetness, umami, salty taste, bitterness, acidity, richness and richness of the sample were observed compared to the blank. The number of persons in the table indicates the number of persons who felt that each of the 14 evaluated persons was enhanced compared to the blank. Moreover,% in parenthesis shows the ratio when 14 people are considered as 100%.

[0029]
As shown in Table 4, most of the panelists in the vegetable extracts were also evaluated to have enhanced umami, richness and richness due to the addition of ammonium glutamate. However, with cabbage extract, there is almost no effect at 0.01% on umami, and 57% of panelists recognized the effect at 0.05%, but with other kombu extract, shiitake extract, and radish extract, 0.01% and 0.05% The effect did not differ greatly between the two, and the way in which the effect appeared differed depending on the type of extract. Similarly to the case of seafood-based extracts, ammonium L-glutamate had a relatively small influence on bitterness and sourness, and 0 to about 40% of panelists were evaluated to have an effect on sweetness and saltiness. From this, also in the vegetable extract, the effect of adding ammonium L-glutamate is mainly in enhancing the taste, richness and richness. However, it was suggested that the effect was greater in the case of the seafood extract.
