Description

【0001】
【発明の属する技術分野】
本発明は、玄米若しくは発芽玄米を使用した加工食品の製造方法に関するものである。
【0002】
【従来の技術及び発明が解決しようとする課題】
例えば、発芽玄米は、玄米に由来する食物繊維,ミネラル,ビタミン等の栄養素が豊富であると共に、発芽により健康に良いとされる種々の効能を有するγ−アミノ酪酸(GABA)が多量に生成され含有されているため、健康に良い食品として近年注目されている。尚、γ−アミノ酪酸には血圧降下作用,精神安定作用,腎機能活性化作用,肝機能改善作用,肥満防止作用,アルコール代謝促進作用,消臭作用等の健康に良いとされる作用を発揮する性質を有することが知られている。また、米(精米前)が有する食物繊維,ミネラル,ビタミン等の栄養素のほとんどは、通常精米時に除去されている表層(糠層)と胚芽に含まれている。
【0003】
しかしながら、この玄米若しくは発芽玄米(以下、玄米等という。)は精米に比して著しく堅いため(玄米等の糠層はセルロースやヘミセルロースなどで構成され、微粉化して食品に加えてもざらつきが残るほど堅い。)、米と共に玄米等を用いて味噌や餅などの加工食品を製造する場合、この玄米等を十分に軟かく滑らかな状態とすることができず、よって、製造された味噌や餅などにはざらつきが残ってしまい舌ざわりが良くない食品となってしまうという問題点を有する。
【0004】
そのため、栄養価が高く、栄養バランスに秀れた健康に良いこの玄米等を食品に加える量はおのずと制限され、多量に含有させることはできないのが現状である。
【0005】
そこで、上記問題点を解決しようとするものとして、例えば、玄米等を粉体化して食品に加えることなどが提案されているが、この粉体化した玄米等を多量に加えれば、やはり食品にはざらつきが残ってしまい舌ざわりが良くない食品となってしまう。
【0006】
また、玄米及び発芽玄米を味噌等の発酵食品に用いる際には通常は麹化されているが、精米の2倍以上の熱量を加えて加熱しても、表層に麹菌が生育せず低品質の麹となる。
【0007】
また、玄米等の糠層を研磨してこの糠層に麹菌などの菌類を繁殖させ易くし、加熱し発酵させることで味噌を製造する方法も提案されてはいるが、栄養素を多分に含む糠層を研磨することで、せっかくの栄養価の高い発芽玄米等から食物繊維などの栄養素が除去されてしまい、食物繊維,ミネラル,ビタミン等の栄養素に富む玄米等を使用しても、あまり栄養価の高い味噌を製造できないという問題点がある。
【0008】
本発明は、繰り返し行った研究,検討により、上記問題点を解決したもので、堅い表層(糠層)を有する玄米若しくは発芽玄米をざらつきのない滑らかな物性の液化糖化物にして食品に加えることで玄米若しくは発芽玄米を多量に使用した栄養価が高く栄養バランスの良い食品を製造することができる用途性,実用性に秀れた画期的な玄米若しくは発芽玄米を使用した加工食品の製造方法を提供することを目的としている。

【0046】
以下、本実施例の具体的な実験例を示す。
【0047】
第一実験例(発芽玄米入り味噌の製造方法)
先ず、発芽玄米30kgを1日間水に浸漬した。
【0048】
水切りした後、セイロに入れ、1時間蒸した。
【0049】
蒸した発芽玄米に温水6リットルを加え吸水させた。尚、この温水は40℃以上の温度に設定するのが好ましい。
【0050】
この吸水させた蒸した発芽玄米をチョッパーで磨砕し、磨砕物を得た。
【0051】
磨砕物に、酵素剤を添加して約55℃で略24時間反応させて発芽玄米液化糖化物を得た。
【0052】
この発芽玄米液化糖化物43kgに大豆麹(大豆に麹菌を接種して得た麹)18kg,蒸煮大豆26kg,食塩11kgを混合し、30℃で60日間発酵・熟成して100kgの発芽玄米入りの味噌を得た。
【0053】
第一実験例によれば、ざらつきのない滑らかな食感の味噌を製造できることが確認された。
【0054】
従って、発芽玄米を多量に使用してもざらつきが生じない栄養価が高く栄養バランスの良い、美味しい発芽玄米入り味噌を製造できるといえる。
【0055】
第二実験例(麹漬けの漬床の製造)
発芽玄米100kgを洗浄し、水に所定時間浸漬した。
【0056】
次いで、この発芽玄米を粉砕し、所定時間蒸した後、糊化した。
【0057】
次いで、この糊化した発芽玄米と、米麹45kgと、塩36kgと、水8リットルとを混合し、室温50℃〜60℃で30時間加温し液化糖化して、麹漬け床230kgを生産した。
【0058】
第二実験例によれば、化学調味料等を添加することなく、発芽玄米液化糖化物が生み出す甘味と塩だけを調味料としたざらつきのない浅漬の素を製造できることが確認された。従って、発芽玄米を多量に使用してもざらつきが生じない栄養価が高く栄養バランスが良い漬床を製造できるといえる。
【0059】
第三実験例(発芽玄米の加工適性の確認)
第三実験例は、水に浸漬した発芽玄米を以下の条件で処理することで、加工適性の確認を行った。尚、蒸し条件は抜け掛け法(浸漬米を薄い層にして蒸気を通し蒸気が吹き抜けたら更に浸漬米を重ねてゆく方法)を採用した。
【0060】
即ち、水に浸漬した発芽玄米は、そのままでは表層(糠層)が硬く、加工適性は不適であった。
【0061】
一方、水に浸漬した発芽玄米を割砕したものは、表層(糠層)が破壊されているため、加工適性は割砕しないそのままのものよりも良くやや扱い易いが、ざらつき等の舌ざわりの問題は残ると考えられた。
【0062】
以上の加工適性の確認により、水に浸漬した発芽玄米を割砕したもの30kgに酵素剤20gと水6リットルとを加えて混合した後、52℃〜55℃の温度で約24時間加温し糖化した。
【0063】
第三実験例によれば、加工適性の高い発芽玄米糖化磨砕物を得ることができた。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a method for producing a processed food using brown rice or germinated brown rice.
[0002]
Problems to be solved by the prior art and the invention
For example, germinated brown rice is rich in nutrients such as dietary fiber, minerals, vitamins, etc. derived from brown rice, and also produces a large amount of γ-aminobutyric acid (GABA), which has various effects considered to be healthy by germination. Since it is contained, it has attracted attention in recent years as a food good for health. In addition, γ-aminobutyric acid exerts effects considered to be good for health, such as a blood pressure lowering action, a tranquilizing action, a renal function activating action, a liver function improving action, an obesity preventing action, an alcohol metabolism promoting action, and a deodorizing action. Is known to have the property of Most of the nutrients such as dietary fiber, minerals, vitamins, and the like, which rice (before rice polishing) has, are contained in the surface layer (bran layer) and germ which are usually removed during rice polishing.
[0003]
However, this brown rice or germinated brown rice (hereinafter referred to as brown rice, etc.) is remarkably harder than polished rice (the bran layer of brown rice, etc. is composed of cellulose, hemicellulose, etc., and remains fine when added to foods after being pulverized. When processing processed foods such as miso and rice cake using brown rice and the like together with rice, the brown rice and the like cannot be made sufficiently soft and smooth, and thus the produced miso and rice cakes However, there is a problem in that the food has a rough texture and the tongue texture is not good.
[0004]
For this reason, the amount of this healthy rice, which has a high nutritional value and a good nutritional balance and is good for health, is naturally limited in the amount of food and cannot be contained in large quantities at present.
[0005]
Therefore, as a solution to the above problems, for example, it has been proposed to powder brown rice or the like and add it to food. Roughness remains, resulting in a food with a poor texture.
[0006]
In addition, when brown rice and germinated brown rice are used in fermented foods such as miso, they are usually kojited, but even if they are heated with more than twice the heat of milled rice, the koji mold does not grow on the surface layer and the quality is low. It becomes koji.
[0007]
Further, a method has been proposed in which a bran layer such as brown rice is polished to facilitate the propagation of fungi such as koji mold in the bran layer, and a miso is produced by heating and fermenting, but a bran containing a large amount of nutrients has been proposed. By polishing the layer, nutrients such as dietary fiber are removed from the highly nutritious germinated brown rice, etc., and even if brown rice, which is rich in nutrients such as dietary fiber, minerals and vitamins, is not so nutritious. The problem is that miso with high quality cannot be produced.
[0008]
The present invention solves the above-mentioned problems through repeated studies and studies, and comprises adding brown rice having a hard surface layer (bran layer) or germinated brown rice to a liquefied saccharified product with smooth physical properties and adding it to food. Method for producing processed foods using epoch-making brown rice or germinated brown rice that is excellent in versatility and practicality that can produce foods with high nutritional value and good nutritional balance using a large amount of brown rice or germinated brown rice It is intended to provide.

[0013]
The method for producing a processed food using brown rice or germinated brown rice according to any one of claims 1 to 3, wherein the liquefaction saccharification is performed at a temperature of 5C to 95C for 1 minute to 30 days. It is related to.
[0014]
The fermented food such as miso, koji pickled floor, amazake, soy sauce, etc. is produced by adding the brown rice liquefied saccharified product to a food and fermenting and aging it. And a method for producing a processed food using brown rice or germinated brown rice.
[0015]
Further, the brown rice liquefied saccharified product, koji such as soybean koji or rice koji, and soybean and salt are mixed and fermented and aged to produce a miso. The present invention relates to a method for producing a processed food using brown rice or germinated brown rice described in (1).
[0016]
BEST MODE FOR CARRYING OUT THE INVENTION
A preferred embodiment of the present invention (how to implement the invention) will be briefly described with reference to its operation and effects.
[0017]
Liquefaction of brown rice or germinated brown rice to obtain a liquefied saccharified product of brown rice by liquefying and saccharifying the brown rice or germinated brown rice, that is, brown rice liquefaction in which the hard surface layer (bran layer) is sufficiently dissolved by liquefaction saccharification of brown rice or germinated brown rice Since it is added to the food as a saccharified product, it is possible to produce a food using unbrown brown rice or germinated brown rice.
[0018]
In this method, brown rice or germinated brown rice is gelatinized by heating, crushed before or after heating, and koji or an enzyme agent is added to the crushed brown rice or germinated brown rice, so that the hard bran layer has a larger surface area. This is because it can be fermented by the fermentation action of koji or an enzyme agent from a gelatinized state that is more easily liquefied, whereby the hard bran layer can be modified into sufficiently smooth physical properties. .
[0019]
In addition, brown rice or germinated brown rice having a hard bran layer can be modified into smooth physical properties without substantially reducing nutrients such as dietary fiber, minerals and vitamins, so that not only miso and mochi but also tofu, ice cream and health drinks Will be easily added.
[0020]
Therefore, according to the present invention, brown rice or germinated brown rice having a hard bran layer can be converted into brown rice liquefied saccharified matter having smooth physical properties, and this is added to food, so that a large amount of brown rice or germinated brown rice is used with little loss of nutrients. It is an unprecedented method for producing processed foods using epoch-making brown rice or germinated brown rice, which can produce various foods with high nutritional value and good nutritional balance.
[0021]
For example, brown rice or germinated brown rice is subjected to at least a heat treatment, a crushing treatment, and a pretreatment of adding water, and then a koji or an enzyme agent is added to liquefy and saccharify to obtain a brown rice liquefied saccharified product. If it is added to food, it becomes more practical, such as a method for producing processed foods using brown rice or germinated brown rice that can reliably exert the above-mentioned effects.
[0022]
Further, for example, when the liquefaction saccharification is performed at a temperature of 5 ° C. to 95 ° C. for 1 minute to 30 days, the above-described effects can be more reliably achieved, and the method is more practical.
[0023]
Further, for example, if fermented foods such as miso, koji pickled floor, amazake, soy sauce, etc. are manufactured by adding the brown rice liquefied saccharified product to food and fermenting and aging, brown rice or germinated brown rice having a high nutritional value and a good nutritional balance can be obtained. The fermented food which is used in a large amount and does not cause roughness can be produced, and thus it becomes more practical.
[0024]
In addition, for example, if the brown rice liquefied saccharified product, koji such as soybean koji or rice koji, and soybeans and salt are mixed and fermented and ripened to produce a miso, a rough surface containing a large amount of brown rice or germinated brown rice is provided. This makes it possible to produce miso with a high nutritional value and a good nutritional balance.
[0025]
【Example】
One embodiment of the present invention will be described below.
[0026]
In the present embodiment, a germinated brown rice liquefied saccharified product (saccharified as shown in FIG. 1) is prepared by subjecting germinated brown rice to at least a pretreatment including a water treatment, a heat treatment, and a pulverization process, and then adding a koji or an enzyme agent to liquefy and saccharify the germinated brown rice.
