Description

本発明は、みりん類の製造法に関する。   The present invention relates to a method for producing mirins.

みりんは、日本の伝統的な醸造食品であり、主に調味料として家庭、飲食店、食品加工の現場で広く使用されている。また、みりんに類似する食品として、アルコール含有調味料、みりん風調味料等と呼ばれるものがみりんと同様の用途に使用されている(以下、みりん、アルコール含有調味料及びみりん風調味料を「みりん類」と総称する)。消費者の嗜好の多様化に伴い、みりん類に求められる味、色、香り、含有成分量或いは調理効果も多様化している。   Mirin is a traditional Japanese brewed food and is widely used as a seasoning mainly at home, restaurants and food processing sites. Also, as foods similar to mirin, what are called alcohol-containing seasonings, mirin-like seasonings, etc. are used for the same purposes as mirin (hereinafter mirin, alcohol-containing seasonings and mirin-like seasonings Generically). With the diversification of consumer preferences, the taste, color, fragrance, content of ingredients and cooking effects required for mirins are also diversifying.

以前より、玄米には、ビタミン、ミネラル、蛋白質、食物繊維が豊富に含まれていることが知られている。また、近年、胚芽又は米糠を利用した健康素材の開発が進んでおり、有効成分であるγアミノ酪酸やセラミド、フェルラ酸、その他有効成分を多く含む米胚芽発酵エキス等が製品化されている。胚芽や米糠をみりんの原料として使用することにより、これら有効成分の含量を増強させたみりん類を開発することができる。   It has long been known that brown rice is rich in vitamins, minerals, proteins, and dietary fiber. In recent years, development of health materials using germ or rice bran has been progressing, and rice germ fermented extract containing a large amount of active ingredients such as γ-aminobutyric acid, ceramide, ferulic acid and other active ingredients has been commercialized. By using germ or rice bran as a raw material for mirin, it is possible to develop mirins with enhanced contents of these active ingredients.

みりん類の原料として米糠をそのまま(生糠)使用する方法や散水せずにそのまま蒸して使用する方法、米糠に対し20〜30%の水を加水(散水)し混和後、蒸して使用する方法は公知である(特許文献1、2参照)。   A method of using rice bran as raw material for mirin (ginger), a method of steaming without sprinkling, a method of adding 20-30% water to rice bran (watering), mixing and steaming Is known (see Patent Documents 1 and 2).

また、清酒醸造の副産物として大量に生産される粳米白糠を利用したみりんの製造研究も行われており、通常、20〜30%の水を加水して蒸した糠を使用するが、生白糠や無散水蒸煮した白糠、エクストルーダーによって成型α化した白糠ペレットを利用する方法も報告されている(非特許文献1〜3参照)
本発明者らは、米糠を利用する技術を用いて、有効成分の含量を増強させたみりん類の開発研究を進めた。生の米糠を原料として利用した場合は、有効成分の溶出が不十分であった。また、米糠に加水せずに蒸煮する方法、及び20〜30%の水を加水して蒸煮する方法では、得られるみりん類の褐変の度合及び焙煎香が強くなることが判明した。褐変の度合及び焙煎香が強いみりん類は、その用途によっては好まれない場合がある。
In addition, research on the production of mirin using glutinous rice bran that is produced in large quantities as a by-product of sake brewing has been carried out, and usually uses cocoon that is steamed with 20-30% water. A method using non-sprinkled steamed birch, white birch pellets molded by an extruder has also been reported (see Non-Patent Documents 1 to 3).
The inventors of the present invention have advanced research and development on mirins having an enhanced active ingredient content using a technique using rice bran. When raw rice bran was used as a raw material, the elution of active ingredients was insufficient. In addition, it was found that the degree of browning and roasted fragrance of the resulting mirins become stronger in the method of cooking without adding water to rice bran and the method of adding 20-30% water and cooking. Mirins with a strong browning degree and strong roasting fragrance may not be preferred depending on the application.

Figure 2007054010
Figure 2007054010

(加水率が米糠の溶解に及ぼす影響)
加水率が米糠の溶解に及ぼす影響を調べるため、米糠1kgに対する加水量を、(1)無散水(加水率0%)、(2)200ml(加水率20%)、(3)300ml(加水率30%)(4)1000ml(加水率100%)、(5)1500ml(加水率150%)、(6)2000ml(加水率200%)と変化させた。水と米糠をよく混合後、水切りし、115℃40分間蒸煮した。この蒸煮米糠に、100gの米麹、アミラーゼ150mg(ユニアーゼS、ヤクルト薬品工業株式会社製)及び40%醸造アルコール700ml、調味液500ml(エキス48%、アルコール14%に液糖とアルコールで調整したもの)と混和して仕込み、30℃20日間糖化熟成し、得られた醪をハンドプレスで圧搾した。仕込み時の醪の状態を撮影した写真を図1に、得られた圧搾液のアミノ酸度、官能評価について表3に示した。
(Effect of water content on dissolution of rice bran)
In order to investigate the influence of the hydrolysis rate on the dissolution of rice bran, the amount of water added to 1 kg of rice bran was determined as follows: (1) Non-watering (hydrolysis rate 0%), (2) 200 ml (hydration rate 20%), (3) 300 ml (hydrolysis rate) 30%), (4) 1000 ml (water content 100%), (5) 1500 ml (water content 150%), and (6) 2000 ml (water content 200%). After thoroughly mixing water and rice bran, drained and steamed at 115 ° C. for 40 minutes. To this steamed rice bran, 100g of rice bran, amylase 150mg (Uniase S, Yakult Pharmaceutical Co., Ltd.) and 40% brewed alcohol 700ml, seasoning solution 500ml (extract 48%, alcohol 14% adjusted with liquid sugar and alcohol) ), And saccharified and matured at 30 ° C. for 20 days, and the resulting koji was squeezed with a hand press. The photograph which image | photographed the state of the wrinkle at the time of preparation was shown in Table 3, and the amino acid degree of the obtained pressing liquid and sensory evaluation were shown in Table 3.

Figure 2007054010
Figure 2007054010

図1より、加水率0〜30%では、蒸煮後の米糠が褐変化するため、結果的に醪の褐変度合いが大きいことが分かる。また、表3より、加水率が100%〜200%の場合は、加水率0〜30%の場合より、アミノ酸含量が多く、米糠の溶解がより良好であることが示された。加水率30%と200%はアミノ酸含量が同程度であり、米糠の溶解程度も同程度と推定されるが、風味の点で加水率200%の方が優れていた。
みりん類の色調については、加水率0〜30%の場合は、吸光度が高く、褐変の度合いが大きかった。熟練したパネルによる官能評価では、加水率が100%〜200%のみりん類は、風味良好と評価された。
From FIG. 1, it can be seen that, at a water addition rate of 0 to 30%, the rice bran after cooking changes brown, and as a result, the degree of browning of the bran is large. Moreover, from Table 3, when the water content was 100% to 200%, the amino acid content was higher and the rice bran was better dissolved than when the water content was 0% to 30%. Although the water content of 30% and 200% have the same amino acid content and the degree of dissolution of rice bran is estimated to be the same, the water content of 200% was superior in terms of flavor.
About the color tone of mirin, when the water content was 0 to 30%, the absorbance was high and the degree of browning was large. In sensory evaluation by a skilled panel, only phosphorus having a water content of 100% to 200% was evaluated as having a good flavor.

(米胚芽の添加効果及び米胚芽における散水の効果)
無散水(加水率0%)の米胚芽と、2倍量の水を散水後(加水率200%)3時間吸水、水切りを行った米胚芽を、加圧釜にて115℃40分間蒸煮した。加水率0%の米胚芽は褐変化し、表面が固くなってしまうことから、米糠同様、加水率200%程度の散水が必要なことが確認できた。蒸煮後の米胚芽の写真を図2に示す。
米糠同様、散水は必要であることが確認できたため、実施例1に従い、コントロール(もち精白米10kg)と試験区(もち精白米8kgに2倍量の水を散水、蒸煮した米胚芽2kg)の仕込みを実施した。得られた圧搾液(みりん類)の分析値を表4に示した。
散水した米胚芽を米原料の一部に使用することにより、アミノ酸含有量や、ミネラル総量、γアミノ酪酸量、抗酸化性が高まり、米胚芽の有効成分を多く含むみりんが得られた。熟練したパネルによる官能評価では、加水率200%のみりん類は、芳醇な味と香りがあり良好と評価された。
(Addition effect of rice germ and watering effect in rice germ)
Non-watering (0% hydrolyzed rice germ) and 2 times the amount of water sprinkled (200% hydrolyzing rate) were water-absorbed and drained for 3 hours, and the rice germ was cooked in a pressure kettle at 115 ° C. for 40 minutes. Since the rice germ with a water content of 0% turns brown and the surface becomes hard, it was confirmed that watering with a water content of about 200% was necessary, as with rice bran. The photograph of the rice germ after cooking is shown in FIG.
As with rice bran, since it was confirmed that watering was necessary, according to Example 1, the control (10 kg of polished rice) and the test area (2 kg of rice germ with 2 times the amount of water sprayed on steamed rice 8 kg) The preparation was carried out. Table 4 shows analytical values of the obtained compressed liquid (mirin).
