Description

【0001】
【発明の属する技術分野】
本発明は、ガラクトマンナン分解物を添加することを特徴とする餅類用品質改良組成物及びそれを用いる餅類の製造法に関するものである。
【0002】
【従来の技術】
餅類は、昔から食されてきた伝統的な食べ物であり、大福餅、おはぎ、ぼた餅、鏡餅、かしわ餅、のし餅、豆餅、団子など、数多くの種類がある。
餅類に含まれる澱粉は、水分存在下で加熱されると糊化、膨張し、餅としての独特な食感を形成する。
餅類の食感としては、やわらかく、なめらかで歯切れが良いことが好まれている。しかしながら、保存中に、α化した澱粉が、時間の経過とともにβ−型に戻る、いわゆる老化現象が起こり、硬くなり食感が低下し、著しく商品価値が低下してしまう。そのため、長い保存期間に耐える品質が強く要求されている。
餅類の品質を改良する方法として、ペクチン、キサンタンガム、カラギーナン、タラガムのような増粘多糖類を餅類に添加することが知られている。しかし、このような増粘多糖類を添加すると粘度が増すため、生地にムラができ易くなる。また、釜ばなれが悪くなるなどの問題が生じる。
他には、特開昭54−49354の酵素を用いる方法、特開平5−252872のオリゴ糖、糖アルコール等の糖類を添加する方法、特開平7−79689のトレハロースとグリセリン脂肪酸エステル等を用いる方法等、多くの試みがなされている。しかしながら、充分に餅類の品質を改良させるに至っていない。
【0003】
【発明が解決しようとする課題】
本発明は、餅類本来の風味を損なうことなく食感を改良し、保存中の老化による餅類の硬化を抑制する餅類用品質改良組成物及びそれを添加することを特徴とする餅類の製造法を提供することを課題とする。
【0004】
【課題を解決するための手段】
本発明者らは前記現状を鑑み、鋭意研究した結果、ガラクトマンナン分解物を含有させることで、餅類の食感を改良し、老化を抑制することができることを初めて見いだし本発明を完成するに至った。すなわち、本発明はガラクトマンナン分解物を含有することを特徴とする餅類用品質改良組成物及びそれを添加することを特徴とする餅類の製造法に関するものである。
【0005】
【発明の実施の形態】
本発明における餅類とは、澱粉(糯米、粳米など)を主成分とする原料を加温しながら混錬し、成型し調製されるものである。例えば、更に限定するものではないが、大福餅、おはぎ、ぼた餅、鏡餅、かしわ餅、豆餅、のし餅などの餅または団子などが挙げられる。
本発明におけるガラクトマンナン分解物とは、人の消化酵素で消化されない難消化性の高分子多糖類であり、ガラクトマンナンを主成分とするグアーガム、ローカストビーンガム、タラガム等の増粘多糖類を加水分解し、精製、乾燥したものである。これらの分解物は、ほとんど無味・無臭で、しかも、水に無色透明に溶解して低粘度の溶液となる。
この加水分解方法については、酵素による方法、酸による方法等、更に限定するものではないが、酸による方法では分解がランダムになり単糖類、二糖類等低分子のものが生成される場合があり一定の分解がされにくいため、酵素による分解が好ましい。酵素分解法に用いられる酵素は、マンノース直鎖を加水分解するものであれば市販のものでも天然由来のものでも更に限定されるものではないが、アスペルギルス属菌やリゾープス属菌等由来のβ−ガラクトマンナナーゼが好ましい。
本発明に使用されるガラクトマンナン分解物は、2,000〜100,000の平均分子量を持つこと、及び1%水溶液をB型粘度計を用いて測定した時の粘度が10mPa・s以下であることが望ましい。平均分子量2,000以上のガラクトマンナン分解物を含有する餅類用品質改良組成物は、いずれも品質改良効果を持っているが、通常、平均分子量が100,000を超えると、粘度が高く餅類に添加する場合に不都合が生じる場合が多いため、糖鎖の平均分子量として2,000〜100,000である事が望ましい。更に好ましくは平均分子量として5,000〜40,000程度に分解したものが望ましい。
平均分子量の測定方法は、更に限定するものではないが、ポリエチレングリコール(分子量;2,000、20,000、100,000)をマーカーに高速液体クロマトグラフ法(カラム;YMC−Pack Diol−120(株)ワイエムシィ社製)を用いて、分子量分布を測定する方法等を用いることにより求めることができる。
【0006】
本発明品の餅類用品質改良組成物は、ガラクトマンナン分解物を含有すればその含有量については更に限定されるものではないが、例えば、原料に対し改善が期待されるガラクトマンナン分解物の有効量即ち、使用時に原料米の0.1〜10重量%、好ましくは、0.2〜5重量%、更に好ましくは、0.5〜2重量%のガラクトマンナン分解物が確保しうる量が含有される事が望ましい。また、他の併用される物質については、更に限定されるものではないが、アミノ酸、ペプチド、オリゴ糖、デキストリン、乳化剤等が挙げられる。
本発明における改良効果のメカニズムについては次の様なことが推測される。水溶性食物繊維の構成成分であるガラクトマンナンが、適度な鎖長に分解され、餅類の澱粉粒子を程良く取り巻くようなかたちでつなぎ剤となるとともに高い保湿効果を有するため餅類の品質改良(食感改良と老化防止)ができるものと考えられる。
本発明品の添加方法は、更に限定するものではないが、従来の糖類の添加方法と同様に、原料米を蒸した後、餅をつく時に添加するのが好ましい。
本発明について、以下に実施例を挙げて具体的に説明するが、これによって限定されるものではない。

BACKGROUND OF THE INVENTION
The present invention relates to a moss quality improving composition characterized by adding a galactomannan degradation product and a method for producing moss using the same.
[0002]
[Prior art]
Rice cakes are traditional foods that have been eaten since ancient times, and there are many types such as Daifuku rice cakes, rice cakes, potato rice cakes, kagami rice cakes, kashiwa rice cakes, rice cakes, bean cakes, and dumplings.
Starch contained in moss gelatinizes and expands when heated in the presence of moisture, forming a unique texture as cocoon.
The texture of moss is preferred to be soft, smooth and crisp. However, during storage, the so-called aging phenomenon occurs in which the starch that has been gelatinized returns to the β-type with the passage of time, becomes harder and has a lower texture, and the commercial value is significantly reduced. Therefore, a quality that can withstand a long storage period is strongly demanded.
As a method for improving the quality of moss, it is known to add thickening polysaccharides such as pectin, xanthan gum, carrageenan and tara gum to moss. However, when such a thickening polysaccharide is added, the viscosity increases, so that unevenness is easily formed on the dough. In addition, problems such as worsening of the hook will occur.
In addition, a method using an enzyme disclosed in JP-A-54-49354, a method including adding a saccharide such as an oligosaccharide or a sugar alcohol disclosed in JP-A-5-252872, and a method using trehalose and a glycerin fatty acid ester disclosed in JP-A-7-79589. Many attempts have been made. However, the quality of moss has not been improved sufficiently.
[0003]
[Problems to be solved by the invention]
The present invention relates to a quality-improving composition for moss that improves the texture without impairing the original flavor of moss and suppresses the curing of moss due to aging during storage, and moss characterized by adding the same It is an object of the present invention to provide a manufacturing method for the above.
[0004]
[Means for Solving the Problems]
As a result of diligent research in view of the present situation, the present inventors have found for the first time that by containing a galactomannan degradation product, the texture of moss can be improved and aging can be suppressed, and the present invention is completed. It came. That is, the present invention relates to a moss quality-improving composition containing a galactomannan degradation product and a method for producing moss characterized by adding it.
[0005]
DETAILED DESCRIPTION OF THE INVENTION
The potatoes in the present invention are prepared by kneading, molding and preparing a raw material mainly composed of starch (brown rice, glutinous rice, etc.). Examples include, but are not limited to, rice cakes or dumplings such as Daifuku rice cake, rice cake, rice cake rice cake, kagami rice cake, kashiwa rice cake, bean rice cake, and rice cake.
The galactomannan degradation product in the present invention is an indigestible polymer polysaccharide that is not digested by human digestive enzymes, and is used to hydrolyze thickening polysaccharides such as guar gum, locust bean gum, and tara gum that are mainly composed of galactomannan. Decomposed, purified and dried. These decomposition products are almost tasteless and odorless, and dissolve in water in a colorless and transparent manner to form a low-viscosity solution.
The hydrolysis method is not limited further, such as an enzymatic method, an acid method, etc., but the acid method may randomly decompose and produce low molecular weight compounds such as monosaccharides and disaccharides. Degradation with an enzyme is preferable because certain degradation is difficult. The enzyme used in the enzymatic degradation method is not limited as long as it hydrolyzes mannose straight chain, either commercially available or naturally derived, but β-derived from Aspergillus or Rhizopus Galactomannanase is preferred.
The galactomannan degradation product used in the present invention has an average molecular weight of 2,000 to 100,000, and has a viscosity of 10 mPa · s or less when a 1% aqueous solution is measured using a B-type viscometer. It is desirable. All the quality-improving compositions for moss containing a galactomannan degradation product having an average molecular weight of 2,000 or more have a quality-improving effect, but when the average molecular weight exceeds 100,000, the viscosity is usually high. Since there are many cases where inconvenience occurs when added to the class, it is desirable that the average molecular weight of the sugar chain is 2,000 to 100,000. More preferably, an average molecular weight decomposed to about 5,000 to 40,000 is desirable.
The method for measuring the average molecular weight is not limited, but high-performance liquid chromatography (column: YMC-Pack Diol-120) using polyethylene glycol (molecular weight; 2,000, 20,000, 100,000) as a marker. It can be determined by using a method for measuring the molecular weight distribution, etc., manufactured by YMC Co.).
[0006]
If the galactomannan degradation product of the product of the present invention contains a galactomannan degradation product, the content thereof is not further limited, but for example, a galactomannan degradation product expected to be improved with respect to the raw material. Effective amount, ie, 0.1-10% by weight of raw rice, preferably 0.2-5% by weight, more preferably 0.5-2% by weight of galactomannan degradation product It is desirable to contain. Further, other substances to be used in combination are not limited, and examples thereof include amino acids, peptides, oligosaccharides, dextrins, and emulsifiers.
About the mechanism of the improvement effect in this invention, the following things are estimated. Galactomannan, a component of water-soluble dietary fiber, is decomposed to an appropriate chain length, becomes a binder in a form that surrounds the starch particles of moss, and has a high moisturizing effect, improving the quality of moss (Improve texture and prevent aging).
The method for adding the product of the present invention is not further limited, but it is preferably added when the rice is cooked after steaming the raw rice, as in the conventional method for adding sugar.
The present invention will be specifically described below with reference to examples, but is not limited thereto.
