Description
本発明は、高度なノウハウや技術を要せず、簡便にジューシーな食感に優れた加熱調理済卵加工食品を作ることができる容器詰め炭酸ガス溶存液卵及びジューシーな食感に優れた加熱調理済卵加工食品の製造方法に関する。 The present invention does not require advanced know-how and technology, and can easily produce a cooked egg processed food excellent in succulent texture and packed in carbon dioxide-dissolved liquid egg, and heated in succulent texture The present invention relates to a method for producing cooked egg processed foods.
熟練した料理人が作る玉子焼き、スクランブルエッグ、錦糸卵、オムレツ等の手作りの加熱調理済卵加工食品は、食感に優れている。
一方、工業的に上記加熱調理済卵加工食品を大量生産する場合には、割卵した原料卵を殺菌、冷凍などの工程を経た液卵を使うため、手作りの食感には大きく劣っていた。
Handmade cooked egg processed foods such as egg-baked eggs, scrambled eggs, tinsel eggs and omelets made by skilled cooks are excellent in texture.
On the other hand, when mass-producing the above cooked egg processed foods industrially, liquid eggs that have undergone processes such as sterilization and freezing are used for the cracked raw eggs. .
そのため、例えば特開平７−２５０６５１号（特許文献１）では、ジューシー感を有する卵加工食品を提供するためにトレハロースとトランスグルタミナーゼを液卵に必須で添加するなど様々な工夫がなされてきた。
しかしながら、添加工程が煩雑である場合や、添加剤が高価な場合が多く、また食感も十分満足するものとは言えなかった。
Therefore, for example, in Japanese Patent Laid-Open No. 7-250651 (Patent Document 1), various ideas have been made such as trehalose and transglutaminase are essentially added to a liquid egg in order to provide a processed egg food having a juicy feeling.
However, the addition process is complicated or the additive is often expensive, and the texture is not sufficiently satisfactory.
そこで、本発明の目的は、高度なノウハウや技術を要せず、簡便にジューシーな食感に優れた加熱調理済卵加工食品を作ることができる液卵及びジューシーな食感に優れた加熱調理済卵加工食品の製造方法を提供するものである。 Accordingly, the object of the present invention is to provide a liquid egg that can easily produce a cooked egg processed food excellent in succulent texture without requiring advanced know-how and techniques, and heat cooking excellent in succulent texture. A method for producing a processed processed egg food is provided.
本発明者は、上記目的を達成すべく鋭意研究を重ねた結果、卵のｐHを下げ、卵を変性させる二酸化炭素を、敢えて液卵に特定量以上溶存し、加熱調理卵加工食品を作ることで、簡便にジューシーな食感に優れた加熱調理済卵加工食品を得られることを見出し、本発明を完成するに至った。 As a result of earnest research to achieve the above-mentioned object, the present inventor has made a cooked egg processed food by lowering the egg pH and deliberately dissolving a certain amount of carbon dioxide that denatures the egg in the liquid egg. Thus, the present inventors have found that a cooked egg processed food excellent in succulent texture can be easily obtained, and the present invention has been completed.

本発明は、容器詰め炭酸ガス溶存液卵において、液卵に特定量以上の炭酸ガスが溶存し、かつ容器詰めされていることを特徴としており、これにより、高度なノウハウや技術を要せず、簡便にジューシーな食感に優れた加熱調理済卵加工食品となる。
<Features of the present invention>
The present invention is characterized in that in a container-packed carbon dioxide-dissolved liquid egg, a specific amount or more of carbon dioxide gas is dissolved in the liquid egg and the container is packed, thereby eliminating the need for advanced know-how and technology. It becomes a cooked and cooked egg processed food excellent in simple and juicy texture.
＜原料卵＞
本発明の容器詰め炭酸ガス溶存液卵に用いる原料卵は、殻付鶏卵を割卵し得られるものであればいずれのものでもよく、例えば、殻付卵を割卵して卵殻を取り除いた液全卵、又は殻付卵を割卵して液卵黄と液卵白とを分離し、再び液卵黄と液卵白とを当該液全卵と同程度の割合で混合したもの、割卵後卵白と卵黄に分離し得られる液卵白、液卵黄などが挙げられる。
液全卵の場合、液卵黄と液卵白との比率は、例えば、生換算で１：１〜１：３程度であればよい。
また、本発明の液卵は、前記原料卵を、更に、撹拌、ろ過、殺菌、脱糖、酵素処理したものや、冷凍後解凍処理したもの、乾燥後水戻し処理を行ったものを用いてもよく、原料卵に後述するその他原料を混合したものであってもよく、更にそれらに炭酸ガスを溶存させたものであってもよい。
なかでも保存性の観点から殺菌処理を行った液卵がよい。
また、卵黄形状が残った状態の液卵（ホール液卵と仮称されている）であると、炭酸ガスが溶存しにくいことから、ホール液卵でない撹拌等の処理を行った液卵がよい。
<Raw eggs>
The raw material egg used for the container-packed carbon dioxide-dissolved liquid egg of the present invention may be any egg as long as it can split a shelled chicken egg, for example, a liquid obtained by cracking a shell egg and removing the eggshell. Split whole egg or shelled egg to separate liquid egg yolk and liquid egg white and mix liquid egg yolk and liquid egg white in the same proportion as the whole liquid egg. And liquid egg white, liquid egg yolk and the like that can be separated.
In the case of liquid whole eggs, the ratio of liquid egg yolk to liquid egg white may be, for example, about 1: 1 to 1: 3 in terms of raw.
In addition, the liquid egg of the present invention uses the raw egg further stirred, filtered, sterilized, desugared, enzyme-treated, frozen and thawed, dried and rehydrated. Alternatively, the raw material egg may be mixed with other raw materials to be described later, and carbon dioxide gas may be further dissolved therein.
Among these, liquid eggs that have been sterilized are preferred from the viewpoint of storage stability.
Moreover, since it is hard to melt | dissolve in a liquid egg (it is tentatively called a whole liquid egg) in the state in which the yolk shape remained, the liquid egg which performed processing, such as stirring which is not a whole liquid egg, is good.
＜炭酸ガスの溶存量＞
本発明の容器詰め炭酸ガス溶存液卵中の炭酸ガスの溶存量の下限値は、１気圧、品温４℃において測定した時の値が、２００ｍｇ／Ｌ以上であり、さらに５００ｍｇ／Ｌ以上がよく、さらに７５０ｍｇ／Ｌ以上がよく、特に１０００ｍｇ／Ｌ以上がよい。
また上限値は特に限定しないが、液卵への炭酸ガスの溶存量に応じた効果が得られ難いことから、液卵への炭酸ガスの溶存量が１気圧、品温４℃において測定した時の値が、４０００ｍｇ／Ｌ以下がよく、さらに３０００ｍｇ／Ｌ以下がよい。
<Dissolved amount of carbon dioxide>
The lower limit value of the dissolved amount of carbon dioxide in the container-packed carbon dioxide-dissolved liquid egg of the present invention is 200 mg / L or more when measured at 1 atm and a product temperature of 4 ° C., and more than 500 mg / L. It is preferably 750 mg / L or more, particularly 1000 mg / L or more.
The upper limit is not particularly limited, but it is difficult to obtain an effect corresponding to the amount of carbon dioxide dissolved in the liquid egg. Therefore, when the amount of carbon dioxide dissolved in the liquid egg is measured at 1 atm and at a product temperature of 4 ° C. Is preferably 4000 mg / L or less, more preferably 3000 mg / L or less.
＜炭酸ガスの測定方法＞
本発明の容器詰め炭酸ガス溶存液卵中の炭酸ガスの溶存量の値は、１気圧、品温４℃とした時に、溶存炭酸ガスセンサ（ＩｎＰｒｏ５０００型ＣＯ２センサ、メトラー・トレド社製）を用いて測定した値である。
<Measurement method of carbon dioxide>
The value of the dissolved amount of carbon dioxide in the container-packed carbon dioxide dissolved liquid egg of the present invention is 1 atm and the product temperature is 4 ° C., using a dissolved carbon dioxide sensor (InPro5000 type CO2 sensor, manufactured by METTLER TOLEDO). It is a measured value.
＜比重＞
本発明の容器詰め炭酸ガス溶存液卵の比重は、１気圧、品温４℃において測定した時の値が、０．９０ｇ／ｃｍ3以上１．１０ｇ／ｃｍ3以下であるとよく、さらに１．００ｇ／ｃｍ3以上１．１０ｇ／ｃｍ3以下であるとよい。
比重が前記数値範囲内であることにより、加熱調理後に食感に優れた卵加工食品が得られ
やすくなる。
<Specific gravity>
The specific gravity of the packaged carbon dioxide dissolved solution egg of the present invention may 1 atm, the value measured at a product temperature 4 ℃, 0.90g / cm 3 or more 1.10 g / cm 3 by mass or less, further 1 It is good that they are 0.000 g / cm 3 or more and 1.10 g / cm 3 or less.
When the specific gravity is within the above numerical range, it becomes easy to obtain an egg processed food having an excellent texture after cooking.
＜比重の測定法＞
予め容積と重さを測ったステンレス容器に、炭酸ガス溶存液卵をステンレス容器の摺り切りまで充填し、その時の重さを測り、ステンレス容器の重さを差し引いた重さを、ステンレス容器の容積で除して、炭酸ガス溶存液卵の比重を測定した。
<Measurement method of specific gravity>
Fill a stainless steel container, which has been previously measured for its volume and weight, with carbon dioxide dissolved egg until the stainless steel container is scraped, measure the weight at that time, and subtract the weight of the stainless steel container to determine the weight of the stainless steel container. The specific gravity of the carbon dioxide-dissolved liquid egg was measured.
＜沈殿物の割合＞
本発明の炭酸ガス溶存液卵を９００ｒｐｍで２０分間遠心分離したときの沈殿物の割合は、炭酸ガス溶存液卵中の原料卵の質量に対し３０％以下がよい。
なお、炭酸ガス溶存液卵は凍結すると沈殿物の質量が増加する傾向があるため、凍結の液卵の場合、上記割合は２０％以下がよりよく、特に１０％以下がよい。また、未凍結の液卵の場合、上記割合は１０％以下がよく、特に５％以下がよい。
また下限値は特に限定しない。
沈殿物の割合が前記数値範囲内であるということは、本発明の炭酸ガス溶存液卵に含まれる変性した卵の凝集物が少ないことを意味し、これにより、加熱調理後に食感に優れた卵加工食品が得られやすくなる。
<Percentage of sediment>
The ratio of the precipitate when the carbon dioxide-dissolved liquid egg of the present invention is centrifuged at 900 rpm for 20 minutes is preferably 30% or less with respect to the mass of the raw material egg in the carbon dioxide-dissolved liquid egg.
In addition, since carbon dioxide-dissolved liquid eggs tend to increase the mass of precipitates when frozen, in the case of frozen liquid eggs, the above ratio is better 20% or less, particularly 10% or less. In the case of an unfrozen liquid egg, the above ratio is preferably 10% or less, and particularly preferably 5% or less.
The lower limit is not particularly limited.
The fact that the ratio of the precipitate is within the above numerical range means that the aggregated amount of the denatured eggs contained in the carbon dioxide-dissolved liquid egg of the present invention is small, and thus the texture is excellent after cooking. It becomes easier to obtain processed egg foods.
＜沈殿物の測定方法＞
本発明の炭酸ガス溶存液卵を９００ｒｐｍで２０分間遠心分離したときの沈殿物の質量は、以下の方法で測定することができる。
すなわち、本発明において、沈殿物量の質量は、炭酸ガス溶存液卵４５ｇを、容積５０ｍＬの遠心管に取り、１気圧、品温４℃下、９００ｒｐｍで２０分間遠心分離処理した後、上層液を除去し、沈殿物の質量を測定した値である。
遠心機は卓上多本架遠心機ＬＣ０６−ＳＰ（株式会社トミー精工製）を用いた。
<Measurement method of sediment>
The mass of the precipitate when the carbon dioxide-dissolved liquid egg of the present invention is centrifuged at 900 rpm for 20 minutes can be measured by the following method.
