Description

本発明は、カットキャベツの製造方法に関する。 The present invention relates to a method for producing cut cabbage.

近年の食生活の多様化とヘルシー志向を反映し、生野菜をそのまま野菜サラダとした加工品の需要が急増している。これに伴い千切りキャベツや、千切り大根、ちぎりレタス等のカット野菜が、袋型、カップ型、ボール型等の種々の食品包装容器に詰められて市場へ大量に提供されるようになってきている。このような容器詰めカット野菜では、雑菌の繁殖により腐敗が進行しやすいことから、店頭販売されるカット野菜については、従来、殺菌処理を徹底させることにより一般生菌数を極力低く抑制してきた。しかし殺菌と同時に、殺菌処理の方法によっては細胞が破壊されることにより、かえって腐敗が進行し易くなったり、野菜本来のシャキシャキした食味を失ったりしてしまうことがあり、腐敗を防止し、一般の家庭の水道水で野菜を洗浄して得られるカットキャベツと同等の野菜本来のシャキシャキした食味と良好な風味を保つことを両立する洗浄条件が望まれている。
そのため、レタスの原体を40度以上44度未満の次亜塩素酸ナトリウム水溶液中において2分間以上6分間以下で洗浄する野菜の洗浄方法(特許文献1)、レタスを約4cm四方に裁断しに浸漬する殺菌方法(引用文献2)が知られている。
Reflecting the diversification of eating habits and health consciousness in recent years, the demand for processed products made from raw vegetables as vegetable salads is increasing rapidly. Along with this, cut vegetables such as shredded cabbage, shredded radish, and chopped lettuce are packed in various food packaging containers such as bag type, cup type, and ball type, and are provided in large quantities to the market. .. Since such containerized cut vegetables are prone to putrefaction due to the propagation of various germs, the number of general viable bacteria has been suppressed as low as possible by thoroughly sterilizing the cut vegetables sold over the counter. However, at the same time as sterilization, depending on the method of sterilization treatment, cells are destroyed, which may lead to the progress of spoilage or the loss of the original crispy taste of vegetables, which prevents spoilage and is generally used. There is a demand for cleaning conditions that achieve both the original crispy taste of vegetables and a good flavor, which is equivalent to that of cut cabbage obtained by washing vegetables with tap water at home.
Therefore, a vegetable washing method (Patent Document 1) in which the original lettuce is washed in an aqueous sodium hypochlorite aqueous solution of 40 degrees or more and less than 44 degrees for 2 minutes or more and 6 minutes or less, and lettuce is cut into about 4 cm squares. A sterilization method for immersion (Reference 2) is known.

本発明者らは、上述の方法で試みられてきた種々の方法で次亜塩素酸ナトリウム水溶液中でのカットキャベツの殺菌処理を試みた。しかしながら、特許文献1の方法では保存時の菌の増殖が十分に抑えきれず、特許文献2の方法では菌の増殖は抑えられたものの、カットキャベツのシャキシャキした食感や風味が損なわれていた。したがって、カットキャベツの殺菌方法にはまだ改善の余地がある。 The present inventors have attempted to sterilize cut cabbage in an aqueous solution of sodium hypochlorite by various methods that have been attempted by the above-mentioned methods. However, the method of Patent Document 1 could not sufficiently suppress the growth of bacteria during storage, and the method of Patent Document 2 suppressed the growth of bacteria, but the crispy texture and flavor of the cut cabbage were impaired. .. Therefore, there is still room for improvement in the method of sterilizing cut cabbage.

本発明の目的は、一般の家庭の水道水で野菜を洗浄して得られるカットキャベツと同等のシャキシャキした食感と良好な風味を有するカットキャベツの製造方法を提供するものである。 An object of the present invention is to provide a method for producing cut cabbage having a crispy texture and good flavor equivalent to that of cut cabbage obtained by washing vegetables with tap water of a general household.

本発明者は、前記目的を達成すべく鋭意検討を重ねた。
その結果、ホールキャベツを特定の液温に調整した殺菌液に接液させて殺菌することにより、意外にも、カット後にもシャキシャキした食感と良好な風味を有すること、また、前記殺菌工程を行うことにより、保存後の一般生菌数が極力低く抑制されており、従来の製造方法で得られるカットキャベツの保存後の一般生菌数と比較し、よりよい状態のカットキャベツが得られることを突き止めた。さらに、カット後の殺菌の有無に関わらず、上記の効果が得られることも見出し、本発明を完成するに至った。
The present inventor has made extensive studies to achieve the above object.
As a result, by sterilizing the whole cabbage by contacting it with a sterilizing solution adjusted to a specific liquid temperature, surprisingly, it has a crispy texture and a good flavor even after cutting, and the sterilizing step is performed. By doing so, the general viable cell count after storage is suppressed as low as possible, and the cut cabbage in a better state can be obtained as compared with the general viable cell count after storage of the cut cabbage obtained by the conventional production method.

In addition, it is possible to suppress the number of general viable bacteria after storage as low as possible regardless of the presence or absence of sterilization after cutting the cabbage. Therefore, it can contribute to improving the quality of cut cabbage and expanding demand.

以下本発明を詳細に説明する。
なお、本発明において「%」は「質量%」を意味する。
Hereinafter, the present invention will be described in detail.
In the present invention, "%" means "mass%".

<本発明の特徴>
本発明は、キャベツを、一定の範囲の液温に調整した特定の殺菌液に浸漬して殺菌を行うことにより、カットキャベツとした後にもシャキシャキした食感と良好な風味を有するカットキャベツが得られることに特徴を有する。
<Features of the present invention>
According to the present invention, by sterilizing cabbage by immersing it in a specific sterilizing solution adjusted to a liquid temperature within a certain range, a cut cabbage having a crispy texture and a good flavor can be obtained even after the cabbage is made into a cut cabbage. It is characterized by being sterilized.

<ホールキャベツを殺菌する工程>
本発明は、ホールキャベツを殺菌する工程において、ホールキャベツを殺菌液に接液させて殺菌する。ホールキャベツを後述する条件で十分に殺菌することにより、カット後の殺菌を行わない場合でも保存後の一般生菌の増殖が抑制されるとともに、シャキシャキした食感と良好な風味を有するカットキャベツが得られる。
ここで、殺菌の対象となる一般生菌としては、代表的には土壌由来の雑菌であって、キャベツに付着してその鮮度を低下させる菌等を挙げることができる。
ホールキャベツを殺菌液に接液させる方法としては、ホールキャベツを浸漬すること、殺菌液をホールキャベツにスプレーすること等を挙げることができる。ここで、ホールキャベツとしては、ホール状から突出している芯等の不可食部を取り除いたものを適用することができ、殺菌工程の前に予め水洗しておいてもよい。
<Process of sterilizing whole cabbage>
In the present invention, in the step of sterilizing whole cabbage, the whole cabbage is sterilized by contacting it with a sterilizing solution. By sufficiently sterilizing the whole cabbage under the conditions described below, the growth of general viable bacteria after storage is suppressed even if the sterilization is not performed after cutting, and the cut cabbage having a crispy texture and good flavor is produced. can get.
Here, examples of general viable bacteria to be sterilized include bacteria that are soil-derived bacteria and that adhere to cabbage to reduce its freshness.
Examples of the method of contacting the whole cabbage with the sterilizing solution include immersing the whole cabbage and spraying the sterilizing solution on the whole cabbage. Here, as the whole cabbage, those obtained by removing the inedible portion such as the core protruding from the hole shape can be applied, and may be washed with water in advance before the sterilization step.

<殺菌温度および殺菌時間>
本発明においては、殺菌温度および殺菌時間を特定の条件に調整して用いることが重要である。具体的には、下式から求められるaが12以上100以下、好ましくは17以上77以下、より好ましくは40以上77以下、さらに好ましくは50以上75以下がよい。
式 a=(b-45)×c b:殺菌温度(℃) c:殺菌時間(分)
aが12未満であると、キャベツの殺菌が不十分となり、保存時の菌の増殖抑制が不十分なものとなる。もしくは、カット後に高濃度の殺菌液を用いた殺菌工程や長時間の殺菌工程が必要なため、カットキャベツのシャキシャキした食感や良好な風味が得られない。aが100超であると、キャベツの外側に熱ダメージが加わってキャベツが柔らかくなり、シャキシャキした食感または風味が弱くなる。加えて、熱ダメージを受けた外側の組織から浸出液が生じやすくなり、保存時の菌の増殖抑制が不十分なものとなる。
<Sterilization temperature and sterilization time>
In the present invention, it is important to adjust the sterilization temperature and sterilization time to specific conditions. Specifically, a determined from the following formula is 12 or more and 100 or less, preferably 17 or more and 77 or less, more preferably 40 or more and 77 or less, and further preferably 50 or more and 75 or less.
Equation a = (b-45) × cb: Sterilization temperature (℃) c: Sterilization time (minutes)
If a is less than 12, the sterilization of cabbage becomes insufficient, and the suppression of bacterial growth during storage becomes insufficient. Alternatively, since a sterilization step using a high-concentration sterilization solution or a long-term sterilization step is required after cutting, the crispy texture and good flavor of the cut cabbage cannot be obtained. When a is more than 100, heat damage is applied to the outside of the cabbage, the cabbage becomes soft, and the crispy texture or flavor becomes weak. In addition, exudates are likely to be generated from the heat-damaged outer tissue, resulting in insufficient suppression of bacterial growth during storage.

<殺菌温度>
本発明においては、殺菌温度を特定の温度に調整する必要があり、具体的には、70℃以下、好ましくは65℃以下であるとよい。殺菌温度が70℃を超えると、キャベツの外側に熱ダメージが加わってキャベツが柔らかくなり、シャキシャキした食感または風味が弱くなる。加えて、熱ダメージを受けた外側の組織から浸出液が生じやすくなり、保存時の菌の増殖抑制が不十分なものとなる。
<Sterilization temperature>
In the present invention, it is necessary to adjust the sterilization temperature to a specific temperature, and specifically, it is preferably 70 ° C. or lower, preferably 65 ° C. or lower. When the sterilization temperature exceeds 70 ° C., heat damage is applied to the outside of the cabbage, the cabbage becomes soft, and the crispy texture or flavor becomes weak. In addition, exudates are likely to be generated from the heat-damaged outer tissue, resulting in insufficient suppression of bacterial growth during storage.

<水溶液>
殺菌工程で用いる水溶液は、次亜塩素酸ナトリウム水溶液、有機酸水溶液、過カルボン酸水溶液のいずれか一種を選択して用いる。

These may be used alone or in combination of two or more.

<カット工程>
前記殺菌工程で殺菌されたキャベツを、例えば、市販のフードスライサー等の切断手段を用いてカット処理する。この際、キャベツの切断部分に清水を注ぎながら行うと、キャベツの断面とカットキャベツの切断面とが常に洗浄されるため、キャベツからの滲出液がカット後のキャベツに付着することが軽減され、保存後の菌の増殖がより抑制されやすくなり好ましい。また、切断面や切断手段へのカットキャベツの付着も軽減され、生産効率の向上も期待できる。さらに、必要に応じてすすぎ処理を施してもよいが、必ずしもこのような処理を施す必要はなく、必要に応じて行えばよい。
<Cut process>
The cabbage sterilized in the sterilization step is cut by using a cutting means such as a commercially available food slicer. At this time, if fresh water is poured into the cut portion of the cabbage, the cross section of the cabbage and the cut surface of the cut cabbage are constantly washed, so that the exudate from the cabbage is less likely to adhere to the cut cabbage. Growth of bacteria after storage is more likely to be suppressed, which is preferable. In addition, adhesion of cut cabbage to the cut surface and cutting means is reduced, and improvement in production efficiency can be expected. Further, a rinsing treatment may be performed if necessary, but such a treatment is not always necessary and may be performed as necessary.

<カット後殺菌工程>
前記カット工程で得られたカットキャベツは、後述の容器詰め工程に投入する前に、必要に応じて殺菌処理してもよい。しかし、本発明に利用するキャベツに、必ずしもこのような工程を施す必要はなく、必要に応じて行えばよい。
カットキャベツに殺菌処理を施す場合、カットキャベツの植物細胞へのダメージを抑制し、シャキシャキした食感と良好な風味を維持する観点から、キャベツの殺菌条件よりも弱い殺菌を施すことが望ましい。
例えば、殺菌液として次亜塩素酸ナトリウム水溶液を用い、殺菌時間は約1分間、有効塩素濃度は80ppm程度、殺菌液の温度は30℃程度で殺菌処理を施す。
<Post-cut sterilization process>
The cut cabbage obtained in the cutting step may be sterilized, if necessary, before being put into the containerizing step described later. However, it is not always necessary to perform such a process on the cabbage used in the present invention, and it may be performed as needed.
When the cut cabbage is sterilized, it is desirable to sterilize the cut cabbage weaker than the sterilization conditions of the cabbage from the viewpoint of suppressing damage to the plant cells of the cut cabbage and maintaining a crispy texture and a good flavor.
For example, an aqueous sodium hypochlorite solution is used as the sterilizing solution, and the sterilizing treatment is performed at a sterilizing time of about 1 minute, an effective chlorine concentration of about 80 ppm, and a sterilizing solution temperature of about 30 ° C.

<すすぎ工程>
前記カット後殺菌工程で得られたキャベツは、後述の容器詰め工程に投入する前に、必要に応じて水洗いですすぎをし、更に水切りしてもよい。しかし、本発明に利用するキャベツに、必ずしもこのような洗浄工程を施す必要はなく、必要に応じて行えばよい。
<Rinse process>
The cabbage obtained in the post-cut sterilization step may be rinsed with water and further drained, if necessary, before being put into the containerizing step described later. However, it is not always necessary to perform such a cleaning step on the cabbage used in the present invention, and it may be performed as needed.

<容器詰め>
前記カット工程で得られたカットキャベツは、前記カット後の殺菌工程を行わずに包装容器に充填し密封してもよい。用いる包装容器は、青果物保存用のプラスチック袋、プラスチック製の勘合容器、トップシール容器等、市販されているものを用いることができる。
<Packing>
The cut cabbage obtained in the cutting step may be filled in a packaging container and sealed without performing the sterilization step after the cutting. As the packaging container to be used, commercially available ones such as a plastic bag for storing fruits and vegetables, a plastic fitting container, and a top seal container can be used.

ホールキャベツの殺菌において表1〜3より、aが12以上100以下の場合(実施例1〜7、参考例1〜2、実施例10〜11)には、製造から3日間後の一般生菌数が対照区1と比較して同等もしくは少なく、一般生菌の増殖が抑制されていることがわかる。また、実施例1の有効塩素濃度が150ppm以上250ppm以下であれば、実施例1とほぼ同等の結果が得られた。
一方、aが12未満、または100超の場合(比較例1〜3)は、一般生菌の増殖が対照区1に比べて抑制されていないことがわかる。
From Tables 1 to 3 in the sterilization of whole cabbage, when a is 12 or more and 100 or less (Examples 1 to 7, Reference Examples 1 to 2, Examples 10 to 11), general viable bacteria 3 days after production. It can be seen that the number is equal to or less than that of the control group 1 and the growth of general viable bacteria is suppressed. Further, when the effective chlorine concentration of Example 1 was 150 ppm or more and 250 ppm or less, almost the same result as that of Example 1 was obtained.
On the other hand, when a is less than 12 or more than 100 (Comparative Examples 1 to 3), it can be seen that the growth of general viable bacteria is not suppressed as compared with the control group 1.

ホールキャベツの殺菌においてaおよびpHが同条件であっても、次亜塩素酸ナトリウム水溶液の有効塩素濃度が70ppm未満(比較例4)であると、一般生菌の増殖が十分に抑制されず、好ましいものではなかった。 Even if a and pH are the same in the sterilization of whole cabbage, if the effective chlorine concentration of the sodium hypochlorite aqueous solution is less than 70 ppm (Comparative Example 4), the growth of general viable bacteria is not sufficiently suppressed. It was not preferable.

また、a、次亜塩素酸ナトリウム水溶液の有効塩素濃度およびpHが同条件であっても、ホールキャベツをリーフ状にした後、約4cm四方に裁断して殺菌した場合(比較例5)は、一般生菌の増殖が対照区1と同等ではあったが、カットキャベツのシャキシャキした食感も風味も弱く、好ましいものではなかった。 Further, a, even if the effective chlorine concentration and pH of the sodium hypochlorite aqueous solution are the same, when the whole cabbage is made into a leaf shape and then cut into about 4 cm squares and sterilized (Comparative Example 5), The growth of general viable bacteria was similar to that of control group 1, but the crispy texture and flavor of the cut cabbage were weak, which was not preferable.

ホールキャベツの殺菌において、a、次亜塩素酸ナトリウム水溶液の有効塩素濃度およびpHが同条件(実施例1〜4)であれば、カット後殺菌の有無に関わらず72時間(製造後3日間)保管したものの一般生菌の増殖が抑制されており、カットキャベツのシャキシャキした食感も風味も感じられる好ましいものであった。よって本発明の方法により得られたカットキャベツは、カット後殺菌工程およびすすぎ工程は必ずしも必要ではない。 In the sterilization of whole cabbage, if a, the effective chlorine concentration and pH of the sodium hypochlorite aqueous solution are the same conditions (Examples 1 to 4), 72 hours (3 days after production) regardless of the presence or absence of post-cut sterilization. Although it was stored, the growth of general viable bacteria was suppressed, and the crispy texture and flavor of the cut cabbage were preferable. Therefore, the cut cabbage obtained by the method of the present invention does not necessarily require a post-cut sterilization step and a rinsing step.

ホールキャベツの殺菌において表4より、pH3以上5以下の有機酸水溶液を用いて殺菌した場合(実施例12)には、72時間(製造後3日間)保管したものの一般生菌数が対照区1と比較して少なく、一般生菌の増殖が抑制され、カットキャベツのシャキシャキとした食感も風味も感じられる好ましいものであったことがわかる。しかし、pH2の場合(比較例6)は、製造から3日間後の一般生菌数が対照区1と比較して少なく、一般生菌の増殖が抑制されているが、カットキャベツのシャキシャキとした食感も風味も好ましいものではなかった。 According to Table 4, in the sterilization of whole cabbage, when sterilized using an organic acid aqueous solution having a pH of 3 or more and 5 or less (Example 12), the general viable cell count was the control group 1 although it was stored for 72 hours (3 days after production). It can be seen that it was preferable that the growth of general viable bacteria was suppressed and the crispy texture and flavor of the cut cabbage were felt. However, in the case of pH 2 (Comparative Example 6), the number of general viable bacteria 3 days after production was smaller than that of Control Group 1, and the growth of general viable bacteria was suppressed, but the cut cabbage was crispy. Neither the texture nor the flavor was favorable.

ホールキャベツの殺菌において表5より、72時間(製造後3日間)保管したものの一般生菌数が対照区1と比較して少なく、一般生菌の増殖が抑制され、カットキャベツのシャキシャキとした食感も風味も感じられる好ましいものであったことがわかる。

According to Table 5, in the sterilization of whole cabbage, the number of general viable bacteria was smaller than that of control group 1 although it was stored for 72 hours (3 days after production), the growth of general viable bacteria was suppressed, and the cut cabbage had a crispy texture. It can be seen that it was a preferable one with both a feeling and a flavor.
