Description

本発明は新規食品素材として、また調味料として使用可能な、うま味、こくが強く、濃厚感があり、さらに食塩を含まない味噌様食材の製造方法に関するものである。   The present invention relates to a method for producing a miso-like food material that can be used as a novel food material and as a seasoning, has a strong umami taste and richness, has a rich feeling, and does not contain salt.

味噌は醸造食品のルーツともいえる日本の伝統的食品であるが、近年、生活の洋風化が進み、味噌の使われる料理も味噌汁が中心となり、その味噌汁の消費も減少傾向にある。そこで、健康食としての味噌の需要を喚起するためにも、現代社会にマッチした味噌を利用した食品の開発が望まれている。しかしながら、味噌は著量の塩分を含み、味噌の多用は塩分の取りすぎにつながるという懸念が強く、味噌の需要は減少しているのが現状である。   Miso is a traditional Japanese food that can be said to be the root of brewed foods. However, in recent years, the lifestyle has become more westernized, and miso soup is mainly used in miso soup. Therefore, in order to stimulate demand for miso as a healthy food, development of foods using miso that matches modern society is desired. However, there is a strong concern that miso contains a significant amount of salt, and that excessive use of miso leads to excessive salt content, and the demand for miso is currently decreasing.

ところで、味噌は、従来より味噌汁のほか、ドレッシング類あるいは各種調味料等に使用される。先述したとおり、味噌をさまざまな用途に用いようとした場合、その塩分が問題となるばかりでなく、味噌に内在する種々の微生物とくに耐熱性バクテリアであるBacillus属細菌が問題となることが多い。すなわち味噌はその製造においてほぼ外気に晒されながら醸造発酵されるため、さまざま微生物が混入する。味噌中では食塩によりそれらの微生物は増殖することがなく問題にならないことが多いが、ドレッシング類などに使用した場合、味噌に内在する微生物がその製品中で増殖し、製品の変敗を招くことがある。   By the way, miso is conventionally used for miso soup, dressings or various seasonings. As described above, when miso is used for various purposes, not only the salt content becomes a problem, but also various microorganisms inherent in the miso, in particular, Bacillus bacteria which are heat-resistant bacteria, often become a problem. In other words, miso is brewed and fermented while being exposed to the outside air in the production thereof, so that various microorganisms are mixed therein. In miso, these microorganisms do not proliferate due to salt and often do not pose a problem. However, when used in dressings, the microorganisms in the miso grow in the product and cause deterioration of the product. There is.

そこで我々は鋭意検討した結果、味噌の製法をベースに、食塩をまったく含まず、さらに内在する微生物、特にBacillus属細菌が検出されない程度まで低減された、まったく新しい味噌様の食品素材の開発に成功した。この食品素材は食塩を含まず、微生物も検出されないばかりでなく、味噌に比べてアミノ酸、特にグルタミン酸の含量が多く、うま味、こく、濃厚感が強く、調味料用途としても、またそのまま喫食される食材としても利用可能な食品素材である。   Therefore, as a result of intensive studies, we succeeded in developing a completely new miso-like food material that does not contain salt at all and is reduced to the extent that it does not detect endogenous microorganisms, particularly bacteria belonging to the genus Bacillus, based on the manufacturing method of miso. did. This food material does not contain salt and microorganisms are not detected, it has a higher content of amino acids, especially glutamic acid than miso, has a strong umami, richness and richness, and it can be eaten as it is as a seasoning It is a food material that can be used as a food material.

従来、減塩味噌や無塩味噌の製法として、希釈及び透析を行った低塩味噌を使用して高蛋白含有食品を製造する方法(特許文献1)、味噌を水で希釈して脱塩味噌を製造する方法(特許文献2)、などさまざまな方法が試みられている。さらに、ナイシンというバクテリオシンを生産する乳酸菌を接種して乳酸発酵することにより、実験室規模において無塩味噌を調製する方法が開示されており、この方法ではバチルス及びその他の汚染細菌は検出されなかったとされている(非特許文献1)。しかしながら、実際の工業的規模での味噌の製造においては、ナイシン生産乳酸菌を加えるだけでは、外気より混入する様々な微生物、特にPediococcus属細菌、Enterococcus属細菌などの乳酸菌が熟成中に著しく増殖し、それらの乳酸菌が産する乳酸によりpHが低下し、いわゆる酸敗が生じる。すなわち、実験室規模での無塩味噌の調製は微生物制御の点で比較的容易であるが、工業規模の製造においては雑菌の制御は非常に困難である。非特許文献1には無塩味噌の工業生産について検討中との記載があるが、具体的な製造条件は開示されておらず、本発明の必須構成要件である、製麹を密閉状態で行うことについて全く言及されていない。また、回転加圧缶を用いて、麹原料の原料処理すなわち散水、蒸煮、冷却及び製麹を同一装置で麹を製造する方法が開示され、その方法では出麹について雑菌が検出されなかったとされている(特許文献3)。しかしながら、特許文献3は麹の培養方法及び装置に関するものであり、食塩非存在下での諸味の分解すなわち無塩味噌の製造に関しては全く言及されていない。また、特許文献3記載の装置は給水蒸気兼用管や容器を回転させる駆動装置など、装置が複雑、高価である。したがって、構造がシンプルで安価な装置を用いて、微生物の混入がなく、無塩下で醸造される食品素材の製造方法の開発が求められている。

Conventionally, as a method for producing low-salt miso or unsalted miso, a method of producing a high protein-containing food using diluted and dialyzed low-salt miso (Patent Document 1), diluting miso with water and desalting miso Various methods such as a method for producing a sol (Patent Document 2) have been tried. Furthermore, a method for preparing salt-free miso on a laboratory scale by inoculating lactic acid bacteria producing nisin bacteriocin and fermenting lactic acid is disclosed, and this method does not detect Bacillus and other contaminating bacteria. (Non-Patent Document 1). However, in the production of miso on an actual industrial scale, by simply adding nisin-producing lactic acid bacteria, various microorganisms contaminated from the outside air, in particular lactic acid bacteria such as Pediococcus bacteria and Enterococcus bacteria, proliferate remarkably during aging, The lactic acid produced by these lactic acid bacteria lowers the pH and causes so-called rancidity. That is, preparation of salt-free miso on a laboratory scale is relatively easy in terms of controlling microorganisms, but control of miscellaneous bacteria is very difficult in production on an industrial scale. Non-Patent Document 1 describes that the industrial production of salt-free miso is under study, but specific production conditions are not disclosed, and the koji making, which is an essential constituent of the present invention, is performed in a sealed state. There is no mention of that. In addition, a method for producing koji using a rotary pressure can in the same apparatus for raw material processing of koji materials, that is, sprinkling, steaming, cooling, and koji making, is disclosed that no germs were detected in the koji. (Patent Document 3). However, Patent Document 3 relates to a method and an apparatus for culturing koji, and does not mention at all about the decomposition of moromi in the absence of salt, that is, the production of a salt-free miso. Further, the device described in Patent Document 3 is complicated and expensive, such as a water supply combined pipe and a driving device for rotating a container. Therefore, there is a demand for the development of a method for producing a food material that is brewed under salt-free conditions, using a simple and inexpensive apparatus, free from microbial contamination.

本発明の効果として、無塩であることから健康感があり、さらに麹菌のプロテアーゼ、ペプチダーゼなどの酵素活性が食塩で阻害されることが無いため、通常の味噌より短い発酵熟成期間で、可溶化窒素、グルタミン酸濃度が、うま味、コク、濃厚感が強い新規味噌様食材をシンプルで安価な装置を用いて提供することが出来る。また該食材は調味料用途としても、食品素材としても使用可能である。   As an effect of the present invention, since it is salt-free, there is a sense of health, and since enzyme activities such as protease and peptidase of koji mold are not inhibited by salt, solubilization can be achieved in a fermentation ripening period shorter than normal miso Nitrogen and glutamic acid concentrations can provide a new miso-like food with strong umami, richness and richness using a simple and inexpensive device. Further, the food can be used as a seasoning or as a food material.

本発明において麹原料として使用する食品素材は、通常の味噌に用いられる大豆、米、麦などを用いることが出来る。必要により、これらの原料を水浸漬処理、蒸煮処理してもよい。   In the present invention, as the food material used as the koji raw material, soybeans, rice, wheat and the like used in normal miso can be used. If necessary, these raw materials may be subjected to water immersion treatment and steaming treatment.

上記原料に抗菌物質であるバクテリオシンを生産する能力のある乳酸菌の培養液若しくはその上清、及び麹菌を混合し、除菌された空気を供給でき、密閉できる製麹機に盛込む。除菌された空気が供給でき、密閉できる製麹機とは、製麹機内に除菌された空気を供給する機能を持ち、製麹機内部と外気を遮断できる構造を持つものであり、例えば回転ドラム式製麹機が挙げられるが、除菌された空気を製麹機内部に供給する構造を持ち、密閉状態が得られる開閉可能な蓋付の製麹機のほうが、構造がシンプルで安価なためより好ましい。空気の除菌方法は0.3μm以上の塵を99.97%以上集塵できるフィルター、例えばHEPAフィルターなどを用いることが出来る。尚、製麹機の排風口には外気を遮断するためフィルターを取り付ける必要がある。密閉できない製麹機、例えば円盤回転式製麹機、静置通風式製麹機などは、外気からの微生物の混入を免れず、特にPediococcus属細菌、Enterococcus属細菌などの乳酸菌が混入し、熟成中に乳酸を生産して、いわゆる酸敗を招く場合がある。通風の方法は特に限定されるものではなく、内部通風方式、表面通風方式などを用いることが出来る。   The above-mentioned raw material is mixed with a culture solution of lactic acid bacteria capable of producing bacteriocin as an antibacterial substance or a supernatant thereof, and koji molds, and sterilized air can be supplied and sealed in a koji making machine that can be sealed. Sterile iron making machine that can supply sterilized air and can be sealed has a function of supplying sterilized air inside the iron making machine and has a structure that can block the inside of the iron making machine from outside air, for example There is a rotating drum type iron making machine, but the iron making machine with a structure that supplies sterilized air to the inside of the iron making machine and has an openable / closable lid is simpler and less expensive. Therefore, it is more preferable. As a method for sterilizing air, a filter capable of collecting 99.97% or more of dust of 0.3 μm or more, such as a HEPA filter, can be used. In addition, it is necessary to attach a filter to the exhaust port of the iron making machine in order to block outside air. Cannot be sealed, for example, disk rotary type, static ventilation type, etc., inevitably mixed with microorganisms from the outside air, especially lactic acid bacteria such as Pediococcus bacteria, Enterococcus bacteria, etc. In some cases, lactic acid is produced, leading to so-called rancidity. The ventilation method is not particularly limited, and an internal ventilation method, a surface ventilation method, or the like can be used.

乳酸菌の培養液若しくはその上清は、例えばナイシン活性が20IU/ml以上のものを、好ましくは200IU/mlのものを、麹原料の0.0001〜0.2倍量、好ましくは0.001〜0.1倍量、より好ましくは0.01〜0.05倍量添加する。0.0001倍量より少ない場合では抗菌作用が少なく、雑菌の汚染を免れない。もちろん、乳酸菌の培養液若しくはその上清のナイシン活性に応じて添加量を変えることはできる。また対麹原料の0.2倍量を超える場合では混合物の水分含量が多くなり、麹菌の生育に悪影響を及ぼす。乳酸菌が生産するバクテリオシンは、ナイシン以外に、ペディオシン、サカシン、ヌカシンなどが挙げられるが、中でも抗菌スペクトルの広さからナイシンを用いることが望ましい。その際、乳酸菌が生産するナイシンの種類はナイシンA、ナイシンZならびにその類縁体どれでもかまわない。微生物の混入、増殖を防ぐには使用する乳酸菌培養液若しくはその上清中のバクテリオシン活性が高い方が望ましい。そこで例えば、ナイシンZを高生産するL.lactis AJ110212(FERM BP−8552)等を使用することが出来る。尚、L.lactis AJ110212株は2003年11月19日に独立行政法人 産業技術総合研究所 特許生物寄託センターにFERM BP−8552の受託番号で寄託されている。   The culture solution of lactic acid bacteria or the supernatant thereof has, for example, a nisin activity of 20 IU / ml or more, preferably 200 IU / ml, 0.0001 to 0.2 times the amount of koji raw material, preferably 0.001 to Add 0.1 times, more preferably 0.01 to 0.05 times. When the amount is less than 0.0001 times, the antibacterial action is small and contamination by various bacteria is inevitable. Of course, the addition amount can be changed according to the nisin activity of the culture solution of the lactic acid bacteria or the supernatant thereof. On the other hand, when the amount exceeds 0.2 times the amount of the raw material for the koji, the water content of the mixture increases, which adversely affects the growth of koji mold. In addition to nisin, bacteriocin produced by lactic acid bacteria includes pediocin, sakacin, and nukacin. Among them, nisin is preferably used because of its wide antibacterial spectrum. At this time, the kind of nisin produced by lactic acid bacteria may be nisin A, nisin Z, or an analog thereof. In order to prevent the contamination and growth of microorganisms, it is desirable that the bacteriocin activity in the lactic acid bacteria culture solution used or its supernatant is high. Therefore, for example, L. lactis AJ110212 (FERM BP-8552), which produces nisin Z at a high rate, can be used. In addition, L. lactis AJ110212 strain was deposited on November 19, 2003 at the National Institute of Advanced Industrial Science and Technology, Patent Biological Deposit Center under the deposit number of FERM BP-8552.

麹菌には味噌同様A.oryzae及び/又はA.sojaeを使用することが出来る。使用する麹菌は原料の蛋白質をアミノ酸、ペプチドまで高分解し、得られる新規味噌様食材に強いうま味、コク、濃厚感を与えることができるものが望ましいが、特に制限をうけるものではない。   As for the koji mold, A.oryzae and / or A.sojae can be used as well as miso. As the koji mold used, it is desirable that the raw material protein can be highly decomposed into amino acids and peptides, and the resulting new miso-like food can give strong umami, richness and richness, but is not particularly limited.

麹原料と乳酸菌培養液若しくはその上清、麹菌の混合物を製麹機内に盛り込んだ後、手入れ(麹菌の生育を促進するために、製麹機内に盛込まれた混合物を例えば10時間毎に攪拌する工程)の際を除いて、製麹機内を密閉した状態で、20〜40℃で17〜62時間、好ましくは24〜34℃で43〜55時間、より好ましくは43〜49時間製麹を行い、麹を得る。製麹温度が40℃を超えると原料蛋白質の分解に必要な酵素活性が低くなり、また温度が20℃未満になると麹菌の生育が悪くなる。いずれの場合も原料蛋白質の分解に必要な酵素を充分得られず、充分なうま味、コク、濃厚感を持った新規味噌様食材を得ることが出来ない。また、製麹時間が17時間未満では麹菌を充分生育させることが困難であり、充分なうま味、コク、濃厚感を持った新規味噌様食材を得ることが出来ない。製麹時間を短くする場合は、麹の生育速度を上げるため、製麹温度を34〜40℃に設定することが望ましい。また、製麹時間が62時間を越えると原料蛋白質の分解に必要な酵素活性が低くなり、充分なうま味、コク、濃厚感が得られないばかりか、苦味が付与される。製麹時間を長くとる場合は、麹の生育速度を下げるため、製麹温度を20〜30℃に設定することが望ましい。尚、手入れの際は、製麹機内部は外気に晒されるため、雑菌の混入の危険性があり、その危険性を最小限に抑えるべく、手入れ工程の総時間、換言すると製麹機の密閉状態が解かれる時間の積算値は、できるだけ短くする必要がある。すなわち、手入れに要する時間を短くするか、手入れ回数を少なくする必要がある。手入れ時間は1回1.5時間以下、好ましくは30分以下、より好ましくは約15分とする。また、手入れ回数であるが、通常約10時間に1回を目安に手入れを行う。従って、少なくとも15.5〜61.5時間、好ましくは16.5〜60.5時間外気から遮断された密閉状態で製麹を行う。   A mixture of a koji raw material and a lactic acid bacteria culture solution or its supernatant and koji mold is placed in a koji making machine, and then maintained (in order to promote koji mold growth, the mixture kneaded in the koji making machine is stirred, for example, every 10 hours. Except for the step), the iron making machine is sealed at 20 to 40 ° C. for 17 to 62 hours, preferably 24 to 34 ° C. for 43 to 55 hours, more preferably 43 to 49 hours. Do and get jealousy. If the koji-making temperature exceeds 40 ° C, the enzyme activity required for the decomposition of the raw material protein becomes low, and if the temperature is less than 20 ° C, the growth of koji molds worsens. In either case, sufficient enzymes necessary for the degradation of the raw material protein cannot be obtained, and a new miso-like food with sufficient umami, richness and richness cannot be obtained. In addition, if the koji making time is less than 17 hours, it is difficult to sufficiently grow the koji mold, and a new miso-like food with sufficient umami, richness and richness cannot be obtained. When shortening the koji-making time, it is desirable to set the koji-making temperature at 34 to 40 ° C. in order to increase the growth rate of koji. Moreover, when the koji-making time exceeds 62 hours, the enzyme activity required for the decomposition of the raw material protein is lowered, and sufficient umami, richness and richness cannot be obtained, and bitterness is imparted. When taking a long time to make the koji, it is desirable to set the koji temperature to 20-30 ° C. in order to reduce the growth rate of the koji. When cleaning, the inside of the iron making machine is exposed to the outside air, so there is a risk of contamination with germs. To minimize this risk, the total time of the maintenance process, in other words, sealing the iron making machine The integrated value of the time for which the state is solved needs to be as short as possible. That is, it is necessary to shorten the time required for maintenance or reduce the number of times of maintenance. The maintenance time is 1.5 hours or less at a time, preferably 30 minutes or less, more preferably about 15 minutes. In addition, although it is the number of times of maintenance, the maintenance is usually performed about once every 10 hours. Therefore, the ironmaking is performed in a sealed state that is blocked from outside air for at least 15.5 to 61.5 hours, preferably 16.5 to 60.5 hours.

次に、得られた麹にナイシン等バクテリオシンを生産する乳酸菌培養液若しくはその上清を諸味の水分含量が35〜60%、好ましくは40〜50%となるように、麹重量の0.01〜5倍量、好ましくは0.1〜1倍量添加し、必要により1種類以上の食品素材を麹重量の0.01〜50倍量添加し、諸味の形成を行う。この場合、「必要により」とは、麹の原料を大豆とした豆麹を用いる場合は、諸味の形成において再度大豆は添加しなくてもよい場合があることを意味する。すなわち、麹の原料を大豆とした場合は、大豆、乳酸菌培養液若しくはその上清、麹菌からなる混合物を製麹した麹に、再び乳酸菌培養液若しくはその上清を添加し、諸味を形成することになる。また、麹に食品素材、例えば大豆、米、麦などを加えてもよい。その場合、あらかじめ蒸煮、もしくは炒煎して用いることができる。例えば、麹の原料を米や麦とした米麹や麦麹を用いる場合、あらかじめ蒸煮もしくは炒煎した大豆を添加することができる。あるいは、豆麹を用いる場合、あらかじめ蒸煮もしくは炒煎した麦や、米を添加することができ、コストダウン目的で大豆を添加することもできる。また、それぞれの植物原料の抽出物、またはその特定成分を加えることもできる。例えば大豆抽出物、米デンプン、小麦ふすまなどが例として挙げられる。またこの食品素材の種類、及び添加量により、色のほか、呈味、風味などをコントロールすることが出来るが、例えば米を添加することにより、甘味を付与することができる。乳酸菌培養液若しくはその上清及び1種類以上の食品素材を麹へ添加する順序は任意であり、麹へ食品素材を添加するのは、乳酸菌培養液若しくはその上清を麹に添加する前でも、後でも、また同時でもよい。   Next, 0.01% of the koji weight is used so that the moromi water content of the lactic acid bacteria culture solution or its supernatant producing bacteriocin such as nisin is 35 to 60%, preferably 40 to 50%. Add 5 to 5 times, preferably 0.1 to 1 times the amount, and if necessary, add one or more food ingredients in an amount 0.01 to 50 times the weight of the bowl to form moromi. In this case, “if necessary” means that when using soybean meal made from soybeans, soybeans may not be added again in the formation of moromi. In other words, when the raw material of koji is soybean, the lactic acid bacteria culture solution or its supernatant is added again to the koji made from a mixture of soybean, lactic acid bacteria culture solution or its supernatant, and koji mold to form moromi. become. In addition, food materials such as soybeans, rice and wheat may be added to the straw. In that case, it can be used by steaming or roasting in advance. For example, when using rice bran or wheat bran with rice or wheat as the raw material for koji, soybeans that have been steamed or roasted in advance can be added. Alternatively, when using soybean meal, wheat or rice that has been cooked or roasted in advance can be added, and soybean can also be added for the purpose of cost reduction. Moreover, the extract of each plant raw material or its specific component can also be added. Examples include soy extract, rice starch, wheat bran and the like. In addition to the color, taste, flavor, and the like can be controlled by the type and amount of the food material. For example, sweetness can be imparted by adding rice. The order in which the lactic acid bacteria culture solution or its supernatant and one or more food materials are added to the koji is arbitrary, and the food material is added to the koji before adding the lactic acid bacteria culture solution or its supernatant to the koji. Later or at the same time.

乳酸菌培養液若しくはその上清の添加量が0.01倍量未満では、微生物の増殖を抑えきれない。また5倍量を超えると、蛋白質の分解が充分でなく、充分なうま味、コク、濃厚感を持った新規味噌様食材を得ることが出来ない。   If the amount of the lactic acid bacteria culture solution or its supernatant added is less than 0.01 times, the growth of microorganisms cannot be suppressed. On the other hand, when the amount exceeds 5 times, the protein is not sufficiently decomposed and a new miso-like food with sufficient umami, richness and richness cannot be obtained.

次に、麹、1種類以上の食品素材とナイシン乳酸菌培養液若しくはその上清の混合物をチョッパーなどですり潰し、ペースト状にして諸味を形成する。その諸味を20〜50℃、好ましくは20〜45℃、より好ましくは25〜35℃に保温し、1〜50日間、好ましくは3〜30日間、より好ましくは4〜14日間、さらに好ましくは4〜9日間発酵熟成し、加水分解する。温度が20℃未満では蛋白質の分解が充分でなく、充分なうま味、コク、濃厚感を持った新規味噌様食材を得ることが出来ない。また50℃を超える温度では諸味に含まれる糖とアミノ酸が反応して、新規味噌様食材に褐変臭、焦げ臭、苦味がついて好ましくない。熟成の日数についても同様の傾向があり、24時間未満であれば蛋白質の分解が充分でなく、充分なうま味、コク、濃厚感を持った新規味噌様食材を得ることが出来ない。また50日間以上では諸味に含まれる糖とアミノ酸が反応して、新規味噌様食材に褐変臭、焦げ臭、苦味がついて好ましくない。   Next, mash a mixture of one or more food materials and a nisin lactic acid bacteria culture solution or its supernatant with a chopper, etc., and paste it to form moromi. The moromi is kept at 20 to 50 ° C., preferably 20 to 45 ° C., more preferably 25 to 35 ° C., and 1 to 50 days, preferably 3 to 30 days, more preferably 4 to 14 days, still more preferably 4 Fermented and matured for ~ 9 days and hydrolyzed. If the temperature is lower than 20 ° C., the protein is not sufficiently decomposed, and a new miso-like food with sufficient umami, richness and richness cannot be obtained. On the other hand, when the temperature exceeds 50 ° C., the sugar and amino acid contained in the moromi react with each other, and the new miso-like food has a browning odor, a burning odor, and a bitter taste. There is a similar tendency with respect to the number of days for ripening. If it is less than 24 hours, the protein is not sufficiently decomposed, and a new miso-like food with sufficient umami, richness and richness cannot be obtained. In addition, the sugar and amino acid contained in the moromi react with each other for 50 days or more, and the new miso-like food material is not preferable because of browning odor, burnt odor, and bitterness.

次に必要な場合は熟成、加水分解が終了した諸味を、50〜130℃で1〜150分間加熱する。加熱の目的は、殺菌、及び諸味に含まれるプロテアーゼなどの酵素を失活させ、保存中の品質変化を防ぐことである。加熱の方法は限定されるものではなく、例えば味噌の火入れに使用される二重管式加熱機、多管式加熱機などが使用でき、また湯浴なども使用することが出来る。50℃未満では殺菌及び酵素の失活が充分でなく、130℃を超えると、褐変臭、焦げ臭、苦味がついて好ましくない。時間についても同様の傾向があり、1分間未満では殺菌及び酵素の失活が充分でなく、150分間を超えると、褐変臭、焦げ臭、苦味がついて好ましくない。   Next, if necessary, the moromi ripened and hydrolyzed is heated at 50 to 130 ° C. for 1 to 150 minutes. The purpose of heating is to sterilize and inactivate enzymes such as protease contained in moromi to prevent quality changes during storage. The heating method is not limited, and for example, a double tube heater, a multi-tube heater, etc. used for miso burning can be used, and a hot water bath can also be used. If it is less than 50 degreeC, disinfection and enzyme deactivation are not enough, and if it exceeds 130 degreeC, browning smell, a burning smell, and a bitter taste are attached, and it is unpreferable. There is a similar tendency with respect to time, and if it is less than 1 minute, sterilization and enzyme deactivation are not sufficient, and if it exceeds 150 minutes, browning odor, burnt odor and bitterness are not preferable.

この新規味噌様食材はペースト状のままで使用することが出来るが、またスプレードライヤー、ドラムドライヤー、バキュームドラムドライヤー、フリーズドライヤーなどで乾燥させ、粉末として使用することも出来る。   This new miso-like food can be used in the form of a paste, but it can also be dried with a spray dryer, drum dryer, vacuum drum dryer, freeze dryer or the like and used as a powder.

本発明の方法で得られる新規味噌様食材は、官能評価によれば、強いうま味、コク、濃厚感を有する。この新規味噌様食材は、各種の飲食品に幅広く利用できる汎用性がある。その特徴として、飲食品にコク、濃厚感を付与し、味質を改善する効果があり、例えばデミグラスソースのような洋風ソース、ポタージュスープなどの洋風スープ、豆板醤のような中華用調味料、つゆ、たれのような和風調味料、またドレッシングなどに使用が出来、さらに従来の味噌では考えられなかった、餡やプリン、アイスクリーム、ケーキなどの菓子類にも使用できる。さらにそのまま食べても充分美味なものであり、わずかな味の調整で大豆に含まれる健康機能を多量に摂食することができる。   The novel miso-like food material obtained by the method of the present invention has strong umami, richness and richness according to sensory evaluation. This new miso-like food has versatility that can be widely used for various foods and drinks. Its characteristics are that it has the effect of adding richness and richness to foods and drinks and improving taste quality.For example, Western-style sauces such as Demigrass sauce, Western-style soups such as potage soup, Chinese seasonings such as soy sauce, soup It can be used for Japanese-style seasonings such as sauce and dressing, and can also be used for confectionery such as candy, pudding, ice cream, cake, etc. Furthermore, even if it is eaten as it is, it is sufficiently delicious, and it is possible to eat a large amount of the health functions contained in soybeans with slight adjustment of taste.

本発明の方法で得られる新規味噌様食材の使用形態は、各種飲食品の製造又は加工時に使用する形態、液状又は顆粒状、粉末状の各種調味料に配合して使用する方法、そのまま喫食する形態等が挙げられる。   The use form of the new miso-like food material obtained by the method of the present invention is the form used in the production or processing of various foods and drinks, the method used by blending with various seasonings in liquid or granular form, powder form, and eating as it is The form etc. are mentioned.

(熟成時間の検討)
大豆50kgを水に浸漬し、吸水させた後、蒸煮釜にて114℃、40分蒸煮した。蒸煮大豆を密閉型製麹機に投入し、さらにL.lactis AJ110212(FERM BP-8552)培養液1kg(ナイシン活性1208IU/ml)、種麹(ビオック社製、豆味噌用種麹)0.05kgを混合し、30℃、43時間製麹した。製麹中の発酵熱の除熱にはHEPAフィルターを通して除菌した空気を用いた。製麹中は、手入れの際を除いて、密閉された状態の製麹機内で製麹した。手入れは製麹開始後10時間毎に15分間、製麹機内部が密閉されておらず外気に晒された状態で行った。得られた麹にL.lactis AJ110212(FERM BP-8552)培養液(ナイシン活性1208IU/ml)を15.4kg添加し、混合した後、チョッパーにより粉砕、ペースト状とした。このペーストをラミネートパウチに1袋につき500gとなるように充填した。このパウチを30℃、3〜60日間保温後、80℃、40分間加熱した。
(Examination of aging time)
50 kg of soybeans were immersed in water and absorbed, and then steamed at 114 ° C. for 40 minutes in a steaming kettle. Steamed soybeans are put into a closed-type koji making machine, and 1 kg of L.lactis AJ110212 (FERM BP-8552) culture solution (Nisin activity 1208 IU / ml), seed koji (by Bioc, bean miso koji) 0.05 kg Were mixed and made at 30 ° C. for 43 hours. Air sterilized through a HEPA filter was used to remove fermentation heat during koji making. During the iron making, the iron making was carried out in a sealed iron making machine, except during the care. Care was performed for 15 minutes every 10 hours after the start of iron making, with the inside of the iron making machine not sealed and exposed to the outside air. 15.4 kg of L. lactis AJ110212 (FERM BP-8552) culture solution (nisin activity 1208 IU / ml) was added to the resulting koji and mixed, and then ground and pasted with a chopper. This paste was filled in a laminated pouch so as to be 500 g per bag. The pouch was kept at 30 ° C. for 3 to 60 days and then heated at 80 ° C. for 40 minutes.

以上の操作によって取得した新規味噌様食材について、可溶化した窒素(可溶化TN)、グルタミン酸濃度、乳酸濃度、pH、及び微生物の分析を行った。また、3名からなる専門の官能評価パネルによる官能評価を行った。官能評価はそのまま食べて評価し、官能評点は5点を満点として3点以上を合格とした。その結果を表1に示す。   The novel miso-like food material obtained by the above operation was analyzed for solubilized nitrogen (solubilized TN), glutamic acid concentration, lactic acid concentration, pH, and microorganisms. In addition, sensory evaluation was performed by a professional sensory evaluation panel consisting of three persons. The sensory evaluation was evaluated by eating it as it was, and the sensory score was a perfect score of 5 points with a score of 3 or more. The results are shown in Table 1.

その結果、全ての実験区において微生物は検出されなかった。また、新規味噌様食材として官能合格であったのは、3〜30日間、うま味、コク、濃厚感が強いのは4〜14日間、評点が高かったのは4〜9日間で、最高点は7日間であった。したがって、熟成、加水分解の期間は3〜30日間、好ましくは4〜14日間、より好ましくは4〜9日間であることが判明した。特筆すべきは可溶化TN及びグルタミン酸の濃度である。一般に市販される豆味噌は、可溶化TNは1.2重量%、グルタミン酸は0.6重量%程度であり、この新規味噌様食材、特に分解期間が7日以上では可溶化TNは2倍以上、グルタミン酸では3倍以上となっており、これが強いうま味、コク、濃厚感を付与するのに寄与している。   As a result, no microorganisms were detected in all experimental sections. In addition, it was sensory pass as a new miso-like ingredient for 3 to 30 days, umami, richness, strong feeling was strong for 4 to 14 days, and the score was high for 4 to 9 days. It was 7 days. Therefore, it has been found that the period of aging and hydrolysis is 3 to 30 days, preferably 4 to 14 days, more preferably 4 to 9 days. Of particular note are the concentrations of solubilized TN and glutamic acid. In general, soybean bean paste marketed has a solubilized TN of about 1.2% by weight and glutamic acid of about 0.6% by weight. This new miso-like food, especially when the degradation period is 7 days or more, the solubilized TN is more than doubled. In glutamic acid, it is more than 3 times, and this contributes to providing a strong umami, richness and richness.
