Description

本発明は、穀類および豆類の除菌方法に関する。より詳細には、本発明は、穀類や豆類の外観、食感、味、風味などを損なうことなくそのまま良好に保持しながら、穀類および豆類に付着している菌類などの微生物を十分に且つ安全に除去して、安全性、衛生性、保存性に優れ、しかも外観、食感、味、風味などにも優れる除菌された穀類および豆類を得る方法に関する。   The present invention relates to a method for sterilizing cereals and beans. More specifically, the present invention is sufficient and safe for microorganisms such as fungi adhering to cereals and beans, while maintaining the cereals and beans without damaging the appearance, texture, taste, flavor, etc. The present invention relates to a method for obtaining sterilized cereals and beans that are excellent in safety, hygiene and storage, and excellent in appearance, texture, taste and flavor.

穀類や豆類の表面には、一般に真菌類などの菌が付着している。菌が多く付着した穀類や豆類は保存時に変質を生ずる場合があり、また衛生上や安全性などの点でも望ましいものではない。また、穀類や豆類は粉にして用いられることも多く、特に小麦、ライ麦、ソバなどは大半が粉にして用いられるが、製粉前の穀類や豆類に菌が多く付着していると、製粉して得られる小麦粉、ソバ粉、ライ麦粉などは菌による汚染度が高くなって、保存性、衛生性、安全性に劣るようになり易い。   Fungi such as fungi are generally attached to the surface of cereals and beans. Cereals and beans with a lot of fungi may be altered during storage, and are not desirable in terms of hygiene and safety. Cereals and beans are often used in powder form, especially wheat, rye, buckwheat, etc., but most are used in powder form. Wheat flour, buckwheat flour, rye flour, etc. obtained by the above method have a high degree of contamination by bacteria, and are likely to be inferior in storage stability, hygiene, and safety.

穀類や豆類の殺菌方法(除菌方法)としては、炭酸ガスやエチレンオキサイドガスなどを用いるガス殺菌法、飽和水蒸気や加熱水蒸気を用いる加熱殺菌法、電子線、X線、γ線などのエネルギー線を照射する方法などが知られている(特許文献1〜4)。
しかし、炭酸ガスを用いる殺菌方法は処理に時間がかかり、しかも気泡が発生するため、ガス処理の手間が必要である。また、エチレンオキサイドガスは残留すると発ガン性物質を生成するため現在は使用が禁止されている。さらに、飽和水蒸気や加熱水蒸気を用いる加熱殺菌法は、穀類や豆類の表面の殺菌には効果があるが、穀類や豆類を高温に曝すため、穀類粒や豆類粒の味、風味の低下、穀類や豆類の内部に含まれている澱粉や蛋白質の変性、変色などが生じ易い。また、電子線、X線、γ線などのエネルギー線を照射する方法は、これらエネルギー線の物質内部への浸透力が大きいため、穀類や豆類の内部に含まれている澱粉や蛋白質の変性や低分子化、穀類や豆類の味、風味の低下などを伴い易く、穀類や豆類の食品としての価値が大きく低下する。その上、エネルギー線を照射するための設備が高価であり、また電子線、X線、γ線などのエネルギー線を扱うものであることから設備の保安・管理に特別の注意が必要である。
As sterilization methods (sterilization methods) for cereals and beans, gas sterilization methods using carbon dioxide gas, ethylene oxide gas, etc., heat sterilization methods using saturated steam or heated steam, energy beams such as electron beams, X-rays and γ-rays And the like are known (Patent Documents 1 to 4).
However, the sterilization method using carbon dioxide gas takes time for the treatment, and bubbles are generated, which requires labor for gas treatment. Moreover, since ethylene oxide gas produces a carcinogenic substance when it remains, its use is currently prohibited. Furthermore, the heat sterilization method using saturated steam or heated steam is effective for sterilizing the surface of cereals and beans, but because cereals and beans are exposed to high temperatures, the taste of grains and beans, the deterioration of flavor, And starch and proteins contained in beans and beans are likely to be denatured and discolored. In addition, the method of irradiating energy beams such as electron beam, X-ray, and γ-ray has a high penetrating power inside these substances, so that starch and proteins contained in grains and beans can be modified and It tends to be accompanied by a decrease in molecular weight, a decrease in the taste and flavor of cereals and beans, and the value of cereals and beans as food is greatly reduced. In addition, the equipment for irradiating energy rays is expensive, and since energy rays such as electron beams, X-rays, and γ rays are handled, special attention is required for the safety and management of the equipment.

また、食品の殺菌には、次亜塩素酸ナトリウムやさらし粉などの塩素系殺菌剤が従来から用いられているが(非特許文献1)、塩素系殺菌剤は、食品の食感、味、風味などの品質の低下を招き易く、しかも塩素系殺菌剤に特有の不快臭による作業環境の悪化などを生じ易い。その上、人体に対する安全性の点で考慮しなければならない塩素系殺菌剤やその分解物が殺菌処理後に食品に多量に残留する恐れがあるため、処理後に水洗処理を十分に行う必要があり、水道水の過剰使用などが生じ易い。   In addition, chlorine-based disinfectants such as sodium hypochlorite and bleached powder have been used for food sterilization (Non-patent Document 1). Chlorine-based disinfectants are food texture, taste and flavor. Such as deterioration of the quality of the work environment, and deterioration of the working environment due to the unpleasant odor peculiar to the chlorine-based disinfectant. In addition, there is a possibility that a large amount of chlorine-based disinfectant and its decomposition products that must be considered in terms of safety to the human body will remain in food after sterilization treatment, so it is necessary to sufficiently wash with water after treatment, Overuse of tap water is likely to occur.

Moreover, it is preferable that the addition amount of the emulsifier in the water for the sterilization treatment used in the sterilization method A is 0 to 1% by mass based on the mass of water, and is 0.001 to 0.1% by mass. More preferably, it is 0.01-0.05 mass%.

除菌方法Aで用いる除菌処理用水のpHは、9.5〜13.5、特に11.5〜12.5であることが、除菌効果が高く、連続処理に対しても安定した効果が得られる点から好ましい。除菌処理用水のpHが、前記範囲よりも低いと、除菌効果が弱くなり易く、一方前記範囲よりも高いと、穀類および豆類の品質の低下、変色などが生じ易くなる。   The pH of the sterilization treatment water used in the sterilization method A is 9.5 to 13.5, particularly 11.5 to 12.5, which has a high sterilization effect and is stable even for continuous treatment. Is preferable from the point that can be obtained. If the pH of the sterilization treatment water is lower than the above range, the sterilization effect tends to be weak, while if it is higher than the above range, the quality of cereals and beans is likely to be deteriorated or discolored.

除菌方法Aでは、穀類または豆類に対する除菌処理用水の付与量(混合量)は、穀類または豆類の種類、穀類または豆類に付着している菌数、穀類または豆類の用途などによって異なり得るが、一般的には、穀類または豆類100質量部に対して、除菌処理用水を200〜5,000質量部、更には300〜3,000質量部、特に500〜1,000質量部の割合で付与(混合)することが、除菌効果、除菌処理時の作業性、除菌処理を終了した後の穀類または豆類の取り扱い性、回収率などの点から好ましい。

また、除菌処理用水の温度は、0〜55℃、特に15〜40℃であることが好ましい。
In the sterilization method A, the application amount (mixed amount) of sterilization water to cereals or beans may vary depending on the type of cereals or beans, the number of bacteria attached to the cereals or beans, the use of the cereals or beans, etc. In general, with respect to 100 parts by mass of cereals or beans, the water for sterilization treatment is 200 to 5,000 parts by mass, more preferably 300 to 3,000 parts by mass, particularly 500 to 1,000 parts by mass. Giving (mixing) is preferable from the viewpoint of the sterilization effect, workability at the time of sterilization treatment, handleability of cereals or beans after the sterilization treatment, recovery rate, and the like.
In addition, the sterilization treatment time of the cereals or beans with the sterilization treatment water (contact time between the sterilization treatment water and the cereals or beans) is generally 1 minute to 2 hours, particularly 5 minutes to 1 hour. Is preferred.
Moreover, it is preferable that the temperature of the water for disinfection treatment is 0-55 degreeC, especially 15-40 degreeC.

除菌方法Aによって除菌処理を行った穀類または豆類は、穀類または豆類の種類、使用目的、除菌処理に続く後加工の有無などに応じて、水などを用いて洗浄してもよいし、水洗浄などを行わずに穀類または豆類を加工する次の処理にそのまま用いてもよいし、水洗浄などを行わずにそのまま乾燥してもよいし、または加熱乾燥してもよい。

The sterilization rate can be further improved by performing sterilization with water for sterilization and then washing with water.

小麦の製粉においては、小麦粒(果皮および種皮を有する小麦粒)から損傷粒、病害粒、砂、土、石、異種穀粒、草の実、その他の異物を分離除去する精選処理を行った後、小麦粒の外側にある果皮および種皮(いわゆるフスマ部分)とその内側にある胚乳部分(小麦粉として回収される部分)の分離が円滑に行われるようにするために、小麦粒に加水する(一般的に水分含量14〜16質量%程度になるように加水)、いわゆる「調質処理」が行われ、その後に果皮および種皮をフスマとして胚乳部分から分離させる挽破処理が行われる。
前記した小麦粒の調質処理の際に、本発明の除菌方法Aを採用して、粘土鉱物とカルシウム成分を添加するかまたは粘土鉱物とカルシウム成分と乳化剤を添加した除菌処理用水を用いて加水(調質)することによって、当該調質処理によって、果皮および種皮(フスマ部分)が胚乳部分から分離し易くなるだけでなく、同時に小麦粒の表面に付着していた菌類などの微生物の除菌(殺菌)が行われて、フスマ部分を分離した後の胚乳部分における菌数が従来よりも低減し、従来よりも菌類の含有量の少ない、保存安定性、安全性、衛生性に優れ、しかも変質の少ない高品質の小麦粉を得ることができる。
かかる点から、除菌方法Aは、小麦製粉における調質処理の際に特に有効である。
In wheat milling, a fine graining process was performed to separate and remove damaged grains, disease grains, sand, earth, stones, heterogeneous grains, grass seeds, and other foreign substances from wheat grains (wheat grains with pericarp and seed coat). Then, in order to facilitate the separation of the pericarp and seed coat on the outside of the wheat grain (so-called bran part) and the endosperm part (part collected as flour) inside it, the water is added to the wheat grain ( In general, water is added so that the water content is about 14 to 16% by mass, so-called “tempering treatment” is performed, followed by a grinding process in which the pericarp and seed coat are separated from endosperm as bran.
In the tempering treatment of the above-mentioned wheat grain, the sterilization method A of the present invention is adopted, and the sterilization treatment water to which the clay mineral and the calcium component are added or the clay mineral, the calcium component and the emulsifier are added is used. By adding water (refining), the refining treatment not only facilitates the separation of the pericarp and seed coat (husma portion) from the endosperm portion, but also the presence of microorganisms such as fungi adhering to the surface of the wheat grain. The number of bacteria in the endosperm portion after sterilization (disinfection) has been reduced and the endosperm portion has been reduced compared to the previous one, and the content of fungi is lower than before, and the storage stability, safety, and hygiene are superior. Moreover, it is possible to obtain high-quality flour with little alteration.
From this point, the sterilization method A is particularly effective at the tempering treatment in wheat flour.

除菌方法Aを、小麦製粉における調質処理の際に採用する場合は、粘土鉱物とカルシウム成分を添加するかまたは粘土鉱物とカルシウム成分と乳化剤を添加した除菌処理用水の小麦粒への混合量は、小麦粒の水分含量が、小麦粒の調質時に一般に採用されている前記した14〜16質量%程度になる量であることが好ましく、実際の混合量は、小麦粒が元々含有する水分含量、並びに粘土鉱物とカルシウム成分を添加した水または粘土鉱物とカルシウム成分と乳化剤を添加した水における水分含量に応じて調節すればよい。
製粉に用いられる小麦粒の水分含量は、一般に6〜13.5質量%程度であり、かかる点から粘土鉱物とカルシウム成分を添加するかまたは粘土鉱物とカルシウム成分と乳化剤を添加した除菌処理用水の小麦粒への混合量は、一般的に小麦粒100質量部に対して、0.5〜10質量部、特に2〜7質量部程度とすればよい。
When adopting the sterilization method A in the tempering treatment in wheat milling, mixing clay minerals and calcium components or mixing sterilization treatment water with added clay minerals, calcium components and emulsifiers into wheat grains The amount of water is preferably such that the moisture content of the wheat grains is about 14 to 16% by mass, which is generally employed during the tempering of the wheat grains, and the actual mixing amount is originally contained in the wheat grains. What is necessary is just to adjust according to the moisture content and the moisture content in the water which added the clay mineral, the calcium component, or the water which added the clay mineral, the calcium component, and the emulsifier.
The water content of wheat grains used for milling is generally about 6 to 13.5% by mass, and from this point, clay minerals and calcium components are added, or water for sterilization treatment added with clay minerals, calcium components and emulsifiers. Generally, the mixing amount of the wheat grains may be about 0.5 to 10 parts by mass, particularly about 2 to 7 parts by mass with respect to 100 parts by mass of the wheat grains.

除菌方法Aは、小麦製粉の際の調質処理の際に行うことが有効であるが、それに限定されるものではなく、上記した種々の穀類または豆類の除菌のために行うことができる。   The sterilization method A is effective to be performed during the tempering process in the case of wheat milling, but is not limited thereto, and can be performed for sterilization of the above-described various grains or beans. .

The sterilization method B is a method in which cereals or beans are immersed in sterilization treatment water to which clay minerals and calcium components are added or clay minerals, calcium components and emulsifiers are added.
The addition amount of the clay mineral in the sterilization treatment water used in the sterilization method B is preferably 0.001 to 5 mass%, more preferably 0.05 to 2 mass%, based on the mass of water. Preferably, it is 0.1-1 mass%. If the amount of clay mineral added is too small, cereals or beans will not be sterilized smoothly.On the other hand, if the amount added is increased after the effect has been saturated, the clay mineral will be wasted and will be removed. Too much adhesion.
Moreover, the addition amount of the calcium component in the water for sterilization treatment used in the sterilization method B is 0.01 to 30% by mass based on the mass of water in terms of the sterilization effect, the adsorption effect, the cleaning effect, and the like. It is preferably 0.5 to 10% by mass, more preferably 1 to 5% by mass. If the amount of calcium component added is too small, cereals or beans will not be sterilized smoothly. On the other hand, if the amount added is too large, precipitation due to saturation will occur and it will be misidentified as a foreign substance.
Moreover, it is preferable that the addition amount of the emulsifier in the water for the sterilization treatment used in the sterilization method B is 0 to 1% by mass, and 0.001 to 0.5% by mass based on the mass of water. More preferably, it is 0.01-0.1 mass%.

除菌方法Bで用いる除菌処理用水のpHは、9.5〜13.5、特に11.8〜12.8であることが、除菌効果が高く、連続処理に対しても安定した効果が得られる点から好ましい。除菌処理用水のpHが、前記範囲よりも低いと、除菌効果が弱くなり易く、一方前記範囲よりも高いと、穀類および豆類の品質の低下、変色などが生じ易くなる。   The pH of the sterilization treatment water used in the sterilization method B is 9.5 to 13.5, particularly 11.8 to 12.8, which has a high sterilization effect and is stable even for continuous treatment. Is preferable from the point that can be obtained. If the pH of the sterilization treatment water is lower than the above range, the sterilization effect tends to be weak, while if it is higher than the above range, the quality of cereals and beans is likely to be deteriorated or discolored.

除菌方法Bによって穀類または豆類の除菌を行うに当たっては、穀類または豆類を除菌処理用の水の中に静置した状態で所定時間放置して浸漬処理してもよいし、穀類または豆類を除菌処理用の水の中で動かしながら所定時間浸漬処理してもよいし、除菌処理用の水の方を撹拌、流動などによって動かしながら所定時間浸漬処理してもよい。穀類または豆類の種類、性質(破損しにくいか破損し易いかなど)、サイズなどに応じて、各々に適した水中浸漬形態を採用すればよい。   In the sterilization of cereals or beans by the sterilization method B, the cereals or beans may be left in the water for sterilization treatment and left for a predetermined time to be immersed, or the cereals or beans May be immersed for a predetermined time while moving in water for sterilization treatment, or may be immersed for a predetermined time while moving the water for sterilization treatment by stirring, flow, or the like. What is necessary is just to employ | adopt the underwater immersion form suitable for each according to the kind, property (whether it is hard to break or it is easy to break), size, etc. of cereals or beans.

穀類または豆類を除菌処理用水中に浸漬して処理する際の除菌処理用水の温度は、一般に0〜50℃、特に15〜40℃であることが好ましい。除菌処理用水の温度が高すぎると穀類または豆類の品質が低下し易くなる。
また、浸漬処理に用いる除菌処理用水の量(浴比)は、1:2〜500(質量比)、特に1:10〜100(質量比)であることが好ましい。
除菌処理用水中への穀類または豆類の浸漬時間は、穀類または豆類の種類、サイズ、性状などに応じて調節する必要があるが、一般的には5分〜48時間、特に10分〜24時間であることが好ましく、前記した範囲から各々の状況に適した浸漬時間を採用するのがよい。
The temperature of the sterilization treatment water when the cereals or beans are treated by immersing them in the sterilization treatment water is generally 0 to 50 ° C, particularly preferably 15 to 40 ° C. If the temperature of the sterilization treatment water is too high, the quality of cereals or beans tends to deteriorate.
Moreover, it is preferable that the amount (bath ratio) of the sterilization treatment water used for the immersion treatment is 1: 2 to 500 (mass ratio), particularly 1:10 to 100 (mass ratio).
The immersing time of cereals or beans in sterilizing water must be adjusted according to the type, size, properties, etc. of cereals or beans, but is generally 5 minutes to 48 hours, particularly 10 minutes to 24. It is preferable to use a time, and it is preferable to use an immersion time suitable for each situation from the above-mentioned range.

穀類または豆類を除菌処理用水中に浸漬して処理する際に、水が例えば前のバッチに用いられていて汚れていると、浸漬処理を行う意味がなくなるので、水の汚染度合いに応じて除菌処理用水の一部または全部を新しいものに取り替えて処理を行ったり、または滅菌設備を備えた循環式の処理装置を用いて除菌処理用水を滅菌しながら処理を行うことが望ましい。   When immersing cereals or beans in sterilizing water and treating them, if the water is used in the previous batch and is dirty, there is no point in immersing it, so depending on the degree of water contamination It is desirable to carry out the treatment by replacing part or all of the sterilization water with a new one, or sterilizing the sterilization water using a circulating treatment device equipped with a sterilization facility.

除菌方法Bによって除菌処理を行った穀類または豆類は、穀類または豆類の種類、使用目的、除菌処理に続く後加工の有無などに応じて、水などを用いて洗浄してもよいし、水洗浄などを行わずに穀類または豆類を加工する次の処理にそのまま用いてもよいし、水洗浄などを行わずにそのまま乾燥してもよいし、または加熱乾燥してもよい。
一般的には、穀類または豆類を除菌処理用水に浸漬して除菌処理したのち、除菌処理用水から取り出し、穀類または豆類を洗浄水中に浸漬するか、穀類または豆類に洗浄水をシャワーしたり流下して洗浄することが、除菌率の一層高い穀類または豆類が得られる点から好ましい。洗浄水を用いて水洗した穀類または豆類は、そのまま次の加工を行ってもよいし、または穀類または豆類の品質低下を招かない温度で乾燥してもよい。
The cereals or beans that have been sterilized by the sterilization method B may be washed with water or the like depending on the type of cereals or beans, the purpose of use, the presence or absence of post-processing following the sterilization treatment, etc. Alternatively, it may be used as it is in the next processing for processing cereals or beans without washing with water, may be dried as it is without washing with water, or may be heat-dried.
Generally, cereals or beans are immersed in sterilization water and sterilized, then removed from the sterilization water, and cereals or beans are immersed in washing water, or cereals or beans are showered with washing water. It is preferable to wash down and wash from the viewpoint of obtaining cereals or beans with a higher sterilization rate. The cereals or beans washed with washing water may be processed as they are, or may be dried at a temperature that does not cause deterioration of the quality of the cereals or beans.

上記した本発明の除菌方法によって、十分に除菌されていて安全性および衛生性に優れ、しかも穀類や豆類が本来有している外観、食感、味、風味などを良好に保持した除菌穀類および除菌豆類が得られる。   By the above-mentioned sterilization method of the present invention, the sterilization is sufficiently sterilized, excellent in safety and hygiene, and maintaining the appearance, texture, taste, flavor, etc. originally possessed by cereals and beans. Fungal cereals and sterilized beans are obtained.
