Description

本発明は、液卵代替組成物及びその凝固物に関する。 The present invention relates to a liquid egg replacer composition and its coagulated product.

近年、健康への配慮や、植物性食品への嗜好の高まり等から、卵を使用せずに植物性タンパク質等の原料を使用し、卵の代わりに調理に用いることができる液卵代替組成物が開発されている。 In recent years, due to health concerns and the growing preference for plant-based foods, liquid egg substitute compositions have been developed that do not use eggs but use ingredients such as vegetable proteins and can be used in cooking instead of eggs.

しかしながら、原料として植物性タンパク質を利用すると、原料特有の風味が付与され、卵らしさが損なわれてしまう。栄養強化の観点からタンパク質を強化しようとすると、植物性タンパク質の配合量も増え、さらに風味を損ねる原因となっていた。
特許文献1には、節類パウダーにより植物性タンパク臭をマスキングする方法が開示されているが、マスキング効果は十分でなく、さらなる改善が望まれている。
However, when vegetable protein is used as an ingredient, the ingredient's unique flavor is imparted, and the egg-like flavor is lost. When trying to increase protein from the perspective of nutritional enhancement, the amount of vegetable protein is increased, which further impairs the flavor.
Patent Document 1 discloses a method of masking the odor of vegetable protein using joint powder, but the masking effect is insufficient, and further improvement is desired.

また、液卵代替組成物は、卵らしい風味と共に、加熱等の処理により本物の卵のように凝固することも求められている。 In addition to having an egg-like flavor, liquid egg replacer compositions are also required to solidify like real eggs when treated with heat or other methods.

そこで、本発明の目的は、液卵代替組成物として求められる凝固性を有し、かつ、植物性タンパク質特有の風味がマスキングされた液卵代替組成物及びその凝固物を提供するものである。 The object of the present invention is to provide a liquid egg replacer composition and its coagulated product that has the coagulation properties required for a liquid egg replacer composition and that masks the flavor specific to vegetable protein.

本発明者らは、上記目的を達成すべく鋭意研究を重ねた。その結果、液卵代替組成物及びその凝固物において、植物由来タンパク質とカルシウムを含有し、前記タンパク質の含有量を3~15%、前記タンパク質1質量部に対する前記カルシウムの含有量を0.003~0.3質量部とすることによって、意外にも、液卵代替組成物として求められる凝固性を有し、かつ、植物性タンパク質特有の風味がマスキングされた液卵代替組成物及びその凝固物が得られることを見出し、本発明を完成するに至った。 The inventors of the present invention have conducted extensive research to achieve the above object. As a result, they have unexpectedly discovered that by containing a plant-derived protein and calcium in a liquid egg replacer composition and a coagulated product thereof, with the protein content being 3 to 15% and the calcium content being 0.003 to 0.3 parts by mass per part by mass of the protein, it is possible to obtain a liquid egg replacer composition and a coagulated product thereof that have the coagulation properties required of a liquid egg replacer composition and in which the flavor specific to the plant protein is masked, and thus have completed the present invention.

本発明によれば、液卵代替組成物として求められる凝固性を有し、かつ、植物性タンパク質特有の風味がマスキングされた液卵代替組成物及びその凝固物を提供することができる。 The present invention can provide a liquid egg replacer composition and its coagulated product that has the coagulation properties required for a liquid egg replacer composition and in which the flavor specific to vegetable protein is masked.

以下本発明を詳細に説明する。なお、本発明において特に規定しない限り、「%」は「質量%」を、「部」は「質量部」を意味する。 The present invention will be described in detail below. In the present invention, unless otherwise specified, "%" means "% by mass" and "parts" means "parts by mass."

<本発明の特徴>
本発明は、植物由来タンパク質とカルシウムを含有する液卵代替組成物であって、前記タンパク質の含有量が3~15%であり、前記タンパク質1質量部に対する前記カルシウムの含有量が0.003~0.3質量部である、液卵代替組成物であることによって、液卵代替組成物として求められる凝固性を有し、かつ、植物性タンパク質特有の風味がマスキングされた液卵代替組成物及びその凝固物を提供できることに特徴を有する。
<Features of the present invention>
The present invention is characterized in that it provides a liquid egg replacer composition containing a plant-derived protein and calcium, the protein content being 3 to 15% and the calcium content being 0.003 to 0.3 parts by mass per part by mass of the protein, thereby providing a liquid egg replacer composition that has the coagulation properties required of a liquid egg replacer composition and in which the flavor specific to the plant protein is masked, and a coagulated product thereof.

<液卵代替組成物>
本発明の液卵代替組成物は、卵を含有しない又は卵を少量含有する液卵代替組成物であって、植物性タンパク質を3~15%含有することを特徴とする。
本発明の液卵代替組成物は、液卵同様に凝固物を調製することができ、本物のスクランブルエッグや炒り卵等の加熱凝固卵に近いそぼろ状の外観を有することが好ましい。
Liquid egg replacer composition
The liquid egg replacer composition of the present invention is a liquid egg replacer composition which does not contain eggs or contains a small amount of eggs, and is characterized by containing 3 to 15% vegetable protein.
The liquid egg replacer composition of the present invention can be used to prepare a coagulated product in the same manner as liquid eggs, and preferably has a minced-like appearance similar to that of real heat-coagulated eggs such as scrambled eggs and fried eggs.

「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%以下、より好ましくは1%以下含有することをいう。 "Does not contain eggs" means that it does not contain ingredients derived from eggs of birds that are generally used for food, such as eggs of chickens, quails, and ducks, and "contains a small amount of eggs" means that the liquid egg replacer composition contains 5% by mass or less, preferably 3% or less, and more preferably 1% or less of ingredients derived from eggs of such birds.

本発明の液卵代替組成物のpHは5.0~8.5であるとよい。pHが前記範囲内であることにより、液卵代替組成物において植物性タンパク質特有の風味をマスキングする効果が得られやすい。 The pH of the liquid egg replacer composition of the present invention is preferably 5.0 to 8.5. By having a pH within this range, the liquid egg replacer composition is more likely to have the effect of masking the flavor specific to vegetable protein.

<凝固物>
本発明の凝固物とは、本発明の液卵代替組成物を用いて調製した凝固物をいう。
本発明の液卵代替組成物を使用する限り、いずれの形態でもよく、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。本発明の凝固物は、加熱凝固卵の代替物として用いることができる。
当該凝固物の製造方法に制限は無く、例えば、加熱又は冷却により凝固させてもよいし、特定の溶液に接触させることで凝固させてもよいが、上記液卵代替組成物をフライパン、湯煎、その他の適当な方法で加熱して、凝固させた加熱凝固物であることが好ましい。
<Coagulated matter>
The coagulated product of the present invention refers to a coagulated product prepared using the liquid egg replacer composition of the present invention.
As long as the liquid egg substitute composition of the present invention is used, any form may be used, and examples thereof include scrambled eggs, omelets, rolled eggs, fried eggs, thin omelets, shredded eggs, and cooked products containing these, etc. The coagulated product of the present invention can be used as a substitute for heat-coagulated eggs.
There is no limitation on the method for producing the coagulated product; for example, the product may be coagulated by heating or cooling, or by contacting the product with a specific solution. However, it is preferable that the liquid egg replacer composition is heated in a frying pan, in a hot water bath, or by other appropriate method to coagulate the product.

<植物性タンパク質>
本発明の液卵代替組成物は植物性タンパク質を含有する。本発明で使用する植物性タンパク質の由来は、例として、大豆、白インゲン豆、赤インゲン豆、エンドウ、緑豆、ルピン豆、ヒヨコ豆、ヒラ豆、ササゲ等の豆類、ゴマ、キャノーラ種子、ココナッツ種子、アーモンド種子等の種子類、とうもろこし、そば、麦、米などの穀物類、野菜類、果物類などが挙げられる。本発明の効果が得られやすいことから、大豆、白インゲン豆、エンドウ豆、アーモンド種子、米から選ばれる1種以上であることが好ましい。
<Plant Protein>
The liquid egg replacer composition of the present invention contains vegetable protein. Examples of the origin of the vegetable protein used in the present invention include beans such as soybeans, white kidney beans, red kidney beans, peas, mung beans, lupine beans, chickpeas, lentil beans, and cowpeas, seeds such as sesame seeds, canola seeds, coconut seeds, and almond seeds, grains such as corn, buckwheat, wheat, and rice, vegetables, and fruits. Since the effects of the present invention can be easily obtained, it is preferable to use one or more selected from soybeans, white kidney beans, peas, almond seeds, and rice.

本発明で使用する植物性タンパク質は、原料の植物性素材を粉砕して粉末状にしたものや、原料の植物性素材からタンパク質を抽出した精製タンパク質を用いることができる。前記精製タンパク質を用いることで、本発明の効果が得られやすい。
なお、植物性タンパク質に対し、必要に応じて、ゲル化性を高めるためのトランスグルタミナーゼ処理等の酵素処理を行うこともできる。
The vegetable protein used in the present invention may be a powder made by pulverizing the vegetable raw material or a purified protein extracted from the vegetable raw material. By using the purified protein, the effects of the present invention can be easily obtained.
If necessary, the vegetable protein may be subjected to an enzyme treatment such as transglutaminase treatment in order to enhance gelling properties.

本発明の液卵代替組成物は、上記植物性タンパク質を3~15%含有する。植物性タンパク質が前記範囲未満の場合、植物性タンパク質の風味が弱く本発明の効果が得られない。また、植物性タンパク質が前記範囲より多い場合、植物性タンパク質の風味を十分にマスキングすることができず、本発明の効果が得られない。
また、本発明の液卵代替組成物は、本発明の効果が得られやすいことから、上記植物性タンパク質を5~14%含有するとよく、7~12%含有するとよりよい。なお、前記植物性タンパク質の割合は、植物性タンパク質から抽出されたタンパク質のみの割合を指し、植物性タンパク質に由来するタンパク質以外の成分は含まない。
The liquid egg replacer composition of the present invention contains 3 to 15% of the above vegetable protein. If the vegetable protein content is less than the above range, the flavor of the vegetable protein is weak and the effects of the present invention cannot be obtained. If the vegetable protein content is more than the above range, the flavor of the vegetable protein cannot be sufficiently masked and the effects of the present invention cannot be obtained.
In addition, the liquid egg replacer composition of the present invention preferably contains the above-mentioned vegetable protein at 5 to 14%, more preferably 7 to 12%, in order to easily obtain the effects of the present invention. Note that the percentage of vegetable protein refers to the percentage of only the protein extracted from the vegetable protein, and does not include any components other than the protein derived from the vegetable protein.

<カルシウム>
本発明の液卵代替組成物は、カルシウムを含有する。
本発明におけるカルシウムは、食品原料由来のカルシウムでもよいし、食品添加物の態様でカルシウムそのものを添加してもよいが、食品添加物の態様でカルシウムそのものを添加した方が、本発明の効果が得られやすい。食品添加物の態様で添加するカルシウムは、食品に添加できるカルシウムであれば特に限定されず、例えば乳酸カルシウム、クエン酸カルシウム、硫酸カルシウム、塩化カルシウム、酢酸カルシウム、グルコン酸カルシウム、ピロリン酸二水素カルシウム、リン酸一水素カルシウム、リン酸二水素カルシウム、リン酸三カルシウム、炭酸カルシウム、グリセロリン酸カルシウム、パントテン酸カルシウム、アスコルビン酸カルシウム、ステアリン酸カルシウム、卵殻カルシウムなどがあるが、特に、乳酸カルシウム、塩化カルシウム、酢酸カルシウム又はグルコン酸カルシウムを配合すると、本発明の効果が得られやすい。
<Calcium>
The liquid egg replacer composition of the present invention contains calcium.
The calcium in the present invention may be calcium derived from food raw materials, or calcium itself may be added in the form of a food additive, but the effect of the present invention is more easily obtained when calcium itself is added in the form of a food additive. The calcium added in the form of a food additive is not particularly limited as long as it is calcium that can be added to food, and examples thereof include calcium lactate, calcium citrate, calcium sulfate, calcium chloride, calcium acetate, calcium gluconate, calcium dihydrogen pyrophosphate, calcium monohydrogen phosphate, calcium dihydrogen phosphate, tricalcium phosphate, calcium carbonate, calcium glycerophosphate, calcium pantothenate, calcium ascorbate, calcium stearate, and eggshell calcium, but the effect of the present invention is more easily obtained when calcium lactate, calcium chloride, calcium acetate, or calcium gluconate is added.

本発明の液卵代替組成物は、植物性タンパク質1質量部に対するカルシウムの含有量が0.003~0.3質量部である。植物性タンパク質とカルシウムの比率が前記下限を下回ると、十分に植物性タンパク質の風味をマスキングすることができず、本発明の効果が得られない。また、植物性タンパク質とカルシウムの比率が前記上限を上回ると、カルシウムのえぐみが強くなり全体の味のバランスが損なわれてしまう。
また、植物性タンパク質1質量部に対するカルシウムの含有量は、0.005~0.1質量部であるとよく、さらに0.008~0.08質量部であるとよい。
カルシウムの含有量は、液卵代替組成物として求められる凝固性を付与しやすく、植物性タンパク質の風味のマスキング効果が得られやすいことから、液卵代替組成物全体に対し、0.01~1%であるとよく、さらに0.05~0.5%であるとよい。
The liquid egg replacer composition of the present invention has a calcium content of 0.003 to 0.3 parts by mass per part by mass of vegetable protein. If the ratio of vegetable protein to calcium is below the lower limit, the flavor of the vegetable protein cannot be sufficiently masked, and the effects of the present invention cannot be obtained. On the other hand, if the ratio of vegetable protein to calcium is above the upper limit, the bitterness of calcium becomes strong, and the overall balance of the taste is impaired.
The calcium content per part by mass of vegetable protein is preferably 0.005 to 0.1 part by mass, and more preferably 0.008 to 0.08 part by mass.
The calcium content is preferably 0.01 to 1%, and more preferably 0.05 to 0.5%, of the total liquid egg replacer composition, since this easily imparts the coagulation properties required of a liquid egg replacer composition and easily provides a masking effect on the flavor of vegetable protein.

<他の原料>
本発明の液卵代替組成物は、本発明の効果を損なわない範囲で、上記以外の原料を含有することができる。このような原料としては、例えば、醤油、食塩、胡椒、アミノ酸等の調味料類、グラニュ糖、上白糖、三温糖、果糖ぶどう糖液糖、澱粉類、デキストリン、フルクトース、トレハロース、グルコース、乳糖、オリゴ糖、糖エタノール等の糖類、グリシン、酢酸ナトリウム等の静菌剤、有機酸、有機酸塩等のpH調整剤、保存料、酸化防止剤、香料、植物性油脂等が挙げられる。
<Other ingredients>
The liquid egg replacer composition of the present invention may contain ingredients other than those mentioned above, provided that the effects of the present invention are not impaired. Examples of such ingredients include seasonings such as soy sauce, salt, pepper, and amino acids, sugars such as granulated sugar, white sugar, brown sugar, high fructose glucose liquid sugar, starches, dextrin, fructose, trehalose, glucose, lactose, oligosaccharides, and sugar ethanol, bacteriostatic agents such as glycine and sodium acetate, pH adjusters such as organic acids and organic acid salts, preservatives, antioxidants, flavorings, and vegetable oils and fats.

<液卵代替組成物の製造方法>
次に、本発明の液卵代替組成物の代表的な製造方法について下記に記載するが、これらは本発明を特に限定するものではない。
具体的には、植物性タンパク質と、カルシウムと、水と、その他の原料と、を攪拌して混合し、液卵代替組成物を調製する。植物性タンパク質は、3~15%となるように調製される。
なお、必要に応じて、加熱殺菌工程を行うこともできる。
<Method of producing liquid egg replacer composition>
Next, representative methods for producing the liquid egg replacer composition of the present invention will be described below, but the present invention is not particularly limited thereto.
Specifically, vegetable protein, calcium, water, and other raw materials are mixed by stirring to prepare a liquid egg replacer composition. The vegetable protein content is adjusted to 3 to 15%.
If necessary, a heat sterilization step can also be carried out.

以下、本発明について、実施例、比較例、及び試験例に基づき具体的に説明する。なお、本発明は、これらに限定するものではない。 The present invention will be specifically described below based on examples, comparative examples, and test examples. Note that the present invention is not limited to these.

<試験例1:植物性タンパク質とカルシウムの比率の検討>
表1に記載の配合で、実施例1~4、比較例1~2の液卵代替組成物を調製した。具体的には、ゲル化剤をあらかじめ水に混合し、ヒスコトロンで5分撹拌して分散させた。その後植物性タンパク質抽出物を溶解させ、その他の原料も加えてよく撹拌し、液卵代替組成物を調製した。
なお、使用した米タンパク質抽出物(「Prodiem Rice 5020」、KERRY GROUP P.L.C.製)は、米タンパク質を87%含んでいた。
<Test Example 1: Examination of the ratio of vegetable protein to calcium>
Liquid egg replacer compositions of Examples 1 to 4 and Comparative Examples 1 and 2 were prepared with the formulations shown in Table 1. Specifically, the gelling agent was mixed with water in advance and dispersed by stirring for 5 minutes using a Hiscotron. The vegetable protein extract was then dissolved, and the other ingredients were added and thoroughly stirred to prepare the liquid egg replacer compositions.
The rice protein extract used ("Prodiem Rice 5020", manufactured by KERRY GROUP P.L.C.) contained 87% rice protein.

Figure 2024077056000002

表2に示すように、植物性タンパク質1質量部に対するカルシウムの含有量が0.003~0.3質量部であることにより、卵代替組成物として求められる凝固性を有し、かつ、植物性タンパク質の風味がマスキングされることが分かった。
また、カルシウム含有量が1.0%以下であると、卵代替組成物として求められる凝固性を有しており、0.5%以下であると、卵代替組成物として求められる凝固性に特に優れていることが理解できる。
As shown in Table 2, it was found that when the calcium content is 0.003 to 0.3 parts by mass per part by mass of vegetable protein, the egg replacer composition has the coagulation properties required for the composition and the flavor of the vegetable protein is masked.
It can also be understood that when the calcium content is 1.0% or less, the composition has the coagulation properties required for an egg replacer composition, and when the calcium content is 0.5% or less, the composition has particularly excellent coagulation properties required for an egg replacer composition.

<試験例2:タンパク質の種類の検討>
実施例1の米タンパク質抽出物を表3に記載のタンパク質抽出物に変更した以外は、実施例1と同様に、実施例5~7の液卵代替組成物を調製した。また、比較例1の米タンパク質抽出物を表3に記載のタンパク質抽出物に変更した以外は、比較例1と同様に、比較例3~5の液卵代替組成物を調製した。
なお、大豆タンパク質抽出物(「プロリーナHD101R」、不二製油株式会社製)は、大豆タンパク質を85%含んでいた。エンドウ豆タンパク質抽出物(「Prodiem Pea 7028」、KERRY GROUP P.L.C.製)は、エンドウ豆タンパク質を78%含んでいた。大手亡豆タンパク質抽出物は以下の方法で調製したものを用い、大手亡豆タンパク質を70%含んでいた。
まず、大手亡豆原料を、外皮を残したまま粉砕して粉体化した。続いて、粉体化された豆原料を水に分散し、水酸化ナトリウムを用いてpH9.0に調整し、タンパク質を溶出させた。タンパク質溶液の上清を回収し、当該上清に塩酸を加えてpH4.5に調整し、タンパク質を沈殿させた。沈殿物を回収し、水酸化ナトリウムを用いてpH7.0となるように中和した。この中和された沈殿物を、大手亡豆タンパク質抽出物として用いた。
<Test Example 2: Examination of protein types>
The liquid egg replacer compositions of Examples 5 to 7 were prepared in the same manner as in Example 1, except that the rice protein extract of Example 1 was changed to the protein extract shown in Table 3. Furthermore, the liquid egg replacer compositions of Comparative Examples 3 to 5 were prepared in the same manner as in Comparative Example 1, except that the rice protein extract of Comparative Example 1 was changed to the protein extract shown in Table 3.
The soy protein extract ("Prolina HD101R", manufactured by Fuji Oil Co., Ltd.) contained 85% soy protein. The pea protein extract ("Prodiem Pea 7028", manufactured by KERRY GROUP P.L.C.) contained 78% pea protein. The soy protein extract was prepared by the following method and contained 70% soy protein.
First, the raw bean was ground into powder while leaving the outer skin. The powdered raw bean was then dispersed in water and adjusted to pH 9.0 with sodium hydroxide to elute the protein. The supernatant of the protein solution was collected, and hydrochloric acid was added to the supernatant to adjust the pH to 4.5 to precipitate the protein. The precipitate was collected and neutralized to pH 7.0 with sodium hydroxide. This neutralized precipitate was used as the raw bean protein extract.

調製した液卵代替組成物を用いて、試験例1と同様に加熱凝固物を調製しその風味及び凝固性を評価した。
その結果、表4に記載の通り、米タンパク質抽出物の代わりに大豆タンパク質抽出物、エンドウ豆タンパク質抽出物、大手亡豆タンパク質抽出物を使った場合でも、植物性タンパク質の風味がマスキングされた。
The prepared liquid egg replacer composition was used to prepare a heat coagulated product in the same manner as in Test Example 1, and its flavor and coagulation properties were evaluated.
As a result, as shown in Table 4, the flavor of vegetable protein was masked even when soybean protein extract, pea protein extract, or whole bean protein extract was used instead of rice protein extract.

<試験例3:pHの検討>
実施例1の液卵代替組成物のpHを変更した実施例8,9を調製した。具体的には、実施例8は塩酸を用いてpH5.0に、実施例9は水酸化ナトリウムを用いてpH9.0にそれぞれ調整した。
調製した液卵代替組成物を用いて、試験例1と同様に加熱凝固物を調製しその風味及び凝固性を評価した。
その結果、pH5.0の実施例8は、実施例1と同様に植物性タンパク質の風味がマスキングされ、また、そぼろ状の非常に卵らしい凝固物が得られた。一方、pH9.0の実施例9は、そぼろ状の非常に卵らしい凝固物が得られたが、風味に関しては、植物性タンパク質の風味がややマスキングされていたものの、実施例1ほどではなかった。
以上より、本発明の液卵代替組成物のpHは、5.0~8.5であることが好ましいことが理解できる。

Examples 8 and 9 were prepared by changing the pH of the liquid egg replacer composition of Example 1. Specifically, Example 8 was adjusted to pH 5.0 using hydrochloric acid, and Example 9 was adjusted to pH 9.0 using sodium hydroxide.
The prepared liquid egg replacer composition was used to prepare a heat coagulated product in the same manner as in Test Example 1, and its flavor and coagulation properties were evaluated.
As a result, in Example 8 at pH 5.0, the flavor of the vegetable protein was masked as in Example 1, and a minced, very egg-like coagulated product was obtained. On the other hand, in Example 9 at pH 9.0, a minced, very egg-like coagulated product was obtained, but the flavor of the vegetable protein was somewhat masked, but not to the same extent as in Example 1.
From the above, it can be seen that the pH of the liquid egg replacer composition of the present invention is preferably 5.0 to 8.5.

<試験例4:カルシウムの種類の検討>
実施例1の乳酸カルシウム五水和物を塩化カルシウム(無水)に変更した以外は、実施例1と同様に、実施例10の液卵代替組成物を調製した。なお、実施例10は、塩化カルシウム(無水)の配合量を調整し、実施例1と同様のカルシウム含有量になるようにした。さらに、調製した液卵代替組成物を用いて、試験例1と同様に加熱凝固物を調製しその風味を評価した。その結果、実施例1と同様に植物性タンパク質の風味がマスキングされ、また、そぼろ状の非常に卵らしい凝固物が得られた。
<Test Example 4: Examination of types of calcium>
A liquid egg replacer composition of Example 10 was prepared in the same manner as in Example 1, except that the calcium lactate pentahydrate of Example 1 was replaced with calcium chloride (anhydrous). In Example 10, the amount of calcium chloride (anhydrous) was adjusted to give a calcium content similar to that of Example 1. Furthermore, a heat coagulated product was prepared using the prepared liquid egg replacer composition in the same manner as in Test Example 1, and its flavor was evaluated. As a result, the flavor of the vegetable protein was masked in the same manner as in Example 1, and a minced, very egg-like coagulated product was obtained.
