しかしながら、植物タンパク質を含有する液卵代替組成物を用いて、スクランブルエッグや炒り卵等のそぼろ状の加熱凝固物を調製しようとすると、加熱凝固物が適度な大きさのそぼろ状にならない等、スクランブルエッグ様や炒り卵様のそぼろ状の外観になり難いという問題があった。また、植物タンパク質のざらつきが感じられるなど食感の問題もあり、外観と食感の両方に優れた加熱凝固物を調製できる液卵代替組成物を得ることは難しかった。この問題に対して本発明者らは、これまでにアーモンドの抽出タンパク質とカードランを組み合わせて用いることにより、外観と食感の両方にすぐれたスクランブルエッグ様の加熱凝固物を調製できる液卵代替組成物が得られることを見出すに至った。
しかしながら、卵焼きやオムレツ等の成形が必要な加熱凝固物を調理しようとすると、外側の凝固物の膜がやや破れやすいという問題があり、さらなる改善が求められていた。
However, when trying to prepare a minced heat-cured product such as a scrambled egg or a fried egg using a liquid egg substitute composition containing vegetable protein, the heat-cured product does not become a minced shape of an appropriate size. There is a problem that it is difficult to obtain a crumbly appearance like a scrambled egg or a fried egg. In addition, there is also the problem of texture, such as the rough texture of the vegetable protein, and it has been difficult to obtain a liquid egg substitute composition that can prepare a heat-cured product that is excellent in both appearance and texture. In response to this problem, the present inventors have so far proposed a liquid egg substitute that can prepare a scrambled egg-like heated coagulum that is excellent in both appearance and texture by using a combination of almond extract protein and curdlan. It has been found that a composition can be obtained.
However, there is a problem that the film of the outer coagulum tends to break when cooking a heated coagulate that requires shaping, such as fried eggs and omelettes, and further improvements have been desired.

以上のような事情に鑑み、本発明の目的は、外観と食感の両方に優れ、かつ膜が破れにくい加熱凝固物を調製できる液卵代替組成物を提供することにある。 In view of the circumstances as described above, it is an object of the present invention to provide a liquid egg substitute composition which is excellent in both appearance and texture, and which allows preparation of a heat-cured product with a film that is resistant to breakage.

本発明者らは、上記目的を達成すべく鋭意研究を重ねた結果、アーモンドの抽出タンパク質とカードランに、さらにメチルセルロースを組み合わせて用いることにより、外観と食感の両方にすぐれたスクランブルエッグ等の加熱凝固物を調製できるだけでなく、卵焼きやオムレツ等の加熱凝固卵様の加熱凝固物を調製した際にも、膜が破れにくい加熱凝固物を調製できることを見出し、本発明を完成するに至った。 As a result of extensive research to achieve the above object, the present inventors have found that by using almond extract protein and curdlan in combination with methyl cellulose, scrambled eggs etc. with excellent appearance and texture can be produced. Not only can a heat-cured product be prepared, but also when preparing a heat-coagulated egg-like heat-coagulated product such as fried eggs and omelets, the inventors have found that a heat-cured product that does not easily break the film can be prepared, and have completed the present invention. .

「卵を含有しない」とは、鶏、鶉、アヒルの卵など、一般に食用に供される鳥類の卵由来の原料を含有していないことをいい、「卵を少量含有する」とは、前記鳥類の卵由来の原料を、液卵代替組成物中に5質量%以下、好ましくは3質量%以下、より好ましくは1質量%以下含有することをいう。
<Liquid egg substitute composition>
The liquid egg substitute composition of the present invention is a liquid egg substitute composition that does not contain eggs or contains a small amount of eggs, and contains 1% by mass or more and 15% by mass or less of almond extract protein, curdlan and methyl cellulose. It is characterized by The liquid egg substitute composition of the present invention can be heated in the same manner as a liquid egg to provide a heated coagulated product having an appearance and texture similar to a heated coagulated egg such as a real scrambled egg or a fried egg, or heated coagulated eggs such as fried eggs and omelets. Like an egg, a heated coagulum can be prepared in which the membrane is less likely to break.
"Does not contain eggs" means that it does not contain raw materials derived from eggs of birds that are generally used for food, such as chicken, quail, and duck eggs. It means that the raw material derived from avian eggs is contained in the liquid egg substitute composition in an amount of 5% by mass or less, preferably 3% by mass or less, more preferably 1% by mass or less.

<液卵>
本発明において、液卵とは、一般に食用に供される鳥類の卵を割卵して得られた液卵白と液卵黄を均一に混合した未加熱の液卵をいう。
液卵は、加熱凝固性を有するため、加熱凝固卵として喫食されることが多い。そのため、液卵の代替物としては、液卵と同等の加熱凝固性を有し、かつ加熱凝固物の食感が加熱凝固卵に近いことが求められる。また、調理に用いやすいことから液卵と同等の流動性を有することが望ましい。
<liquid egg>
In the present invention, liquid eggs refer to unheated liquid eggs obtained by uniformly mixing liquid egg white and liquid egg yolk obtained by cracking eggs of birds generally used for food.
Since liquid eggs are heat-coagulable, they are often eaten as heat-coagulated eggs. Therefore, as a substitute for liquid egg, it is required that it has heat coagulability equivalent to that of liquid egg and that the texture of the heat coagulated product is close to that of heat coagulated egg. In addition, it is desirable to have fluidity equivalent to that of a liquid egg because it is easy to use for cooking.

<加熱凝固卵>
本発明において、加熱凝固卵とは、液卵の加熱凝固物を意味する。加熱凝固卵としては、例えば、スクランブルエッグ、オムレツ、卵焼き、炒り卵、薄焼き卵、錦糸卵、及びこれらを含む調理品等が挙げられる。
<Heat coagulated egg>
In the present invention, the heat-coagulated egg means heat-coagulated liquid egg. Heat-coagulated eggs include, for example, scrambled eggs, omelets, fried eggs, scrambled eggs, thinly fried eggs, thinly sliced omelets, and cooked products containing these.

<加熱凝固物>

The heat-cured material is obtained by heating the liquid egg substitute composition by a frying pan, hot water bath, or other appropriate method to solidify (gelate). The heat-cured product of the present invention can be used as a substitute for heat-cured eggs.

<アーモンドの抽出タンパク質>
本発明の液卵代替組成物は、アーモンドの抽出タンパク質を含有することを特徴とする。アーモンドの抽出タンパク質とは、アーモンドから抽出されたタンパク質をいう。アーモンドの抽出タンパク質は、最適な水への溶解性を有する。すなわち、水への溶解性が低いため、カードランによるゲルネットワークの形成を阻害せずに、そぼろ状の加熱凝固物を調製することができる。一方で、わずかに水に溶解するため、タンパク質粉末のざらつきを感じにくく、食感に優れた加熱凝固物が得られる。さらに、色調の点においても、白色をベースとした淡色の色調を有する。これにより、褐色、黒色又は灰色等の濃色の色調を有する他の植物タンパク質と比較して、加熱凝固卵に近い黄色の色調を再現しやすくなる。さらに、アーモンドの抽出タンパク質は、素材特有の臭いが少ない。これにより、加熱凝固卵の風味により近い加熱凝固物が得られやすい。
このように、本発明の液卵代替組成物は、液卵の代替物として求められる加熱凝固性及び流動性、並びに、加熱凝固卵の代替物として求められる、ざらつきのない食感、淡色の色調及び良好な風味、の全ての性質を兼ね備えている。したがって、本発明によれば、加熱凝固卵を製するための液卵の代替物として、より優れた特性を有する液卵代替組成物を得ることができる。
<Extracted protein from almonds>
The liquid egg substitute composition of the present invention is characterized by containing an almond extract protein. Almond protein extract refers to protein extracted from almonds. Almond protein extract has optimal water solubility. That is, since it has low solubility in water, it is possible to prepare a crumbly heat-cured product without inhibiting the formation of a gel network by curdlan. On the other hand, since it is slightly soluble in water, it is difficult to feel the roughness of the protein powder, and a heated coagulate with excellent texture can be obtained. Furthermore, in terms of color tone, it has a light color tone based on white. This makes it easier to reproduce a yellow color close to that of heat-coagulated eggs compared to other vegetable proteins that have a dark color such as brown, black or gray. In addition, the almond protein extract has less odor peculiar to the material. This makes it easier to obtain a heated coagulated product that is closer to the flavor of the heated coagulated egg.
Thus, the liquid egg substitute composition of the present invention has the heat coagulability and fluidity required as a liquid egg substitute, and the non-gritty texture and light color tone required as a heat coagulated egg substitute. and good flavor. Therefore, according to the present invention, it is possible to obtain a liquid egg substitute composition having superior properties as a liquid egg substitute for producing a heat-coagulated egg.
