Description

【0001】
【発明の属する技術分野】本発明は、穀類加工食品の品質改良に関し、特に保存後のホグレ性や風味等を改良する穀類加工食品の品質改良剤及び品質が改良された穀類加工食品に関する。
【0002】
【従来の技術】米飯や麺類等の穀類加工食品は、一般に時間の経過と共に固くなる。この傾向は常温以下の低温域である方が大きい。この現象は穀類加工食品中に含まれる澱粉の老化によるものであり、水と熱により糊化、膨潤した澱粉が再結晶化するために起こる。また米飯や麺類等で食品同士が結着しホグレ性が悪くなることもある。特に穀類加工食品を低温域で流通、保存した場合、食味、食感、風味、ほぐれ等の品質の劣化が著しく喫食に耐えられないレベルに至る事も多い。
【0003】穀類加工食品における上記のような品質低下を抑制する方法として、澱粉の老化の抑制のためα−アミラーゼ、β−アミラーゼ、グルコアミラーゼ等の酵素類類を添加することがよく行われてきた。またほぐれ性等の品質の劣化に対して大豆多糖類の添加(特許文献1、2)、トレハロース等の還元糖類の添加(特許文献3)さらにトレハロースと大豆多糖類の併用(特許文献4)、環状及び分岐構造を有するグルカンの利用(特許文献5)等による改善の方法が提案されている。さらに、乳化剤と油脂を添加する方法(特許文献6)も知られている。しかしこれら方法では、澱粉の老化抑制に集中するあまり過剰に添加して本来の穀類加工食品の有する食味、食感、風味等の品質の劣化を招くといった別の問題を引き起こしたり、改良の効果が充分でなかったりで、充分満足する方法にまで至っていない現状である。

【0005】又、穀類加工食品は多くの場合、加工後喫食に至る期間の衛生面、他の具材の保存性維持の為、冷蔵(チルド)食品、冷凍食品と言われる形で、低温域にて保存、流通される。これらの添加物を使用した穀類加工食品を低温域にて流通後、喫食する際、澱粉の老化による食味等の品質劣化が起こるが、更に、喫食に適した温度域に再加熱すると食品中の水分が蒸発する等により食味、食感、風味等の品質の劣化を一段と招く傾向にある。又、食品の風味と異なる添加物を使用した場合、風味劣化以上に本来の食品と懸離れた異味が発生する問題もある。
【0006】
【発明が解決しようとする課題】本発明は、穀類加工食品、なかでも冷蔵食品や冷凍食品で、低温域にて穀類加工食品を保存、流通後、そのまま、低温域での解凍や、加熱再調理して喫食する際に、ホグレ性を始め、食味、食感、風味等、品質の劣化を抑制する穀類加工食品用品質改良剤及び品質が改良された穀類加工食品を提供することを目的とする。
【0007】
【課題を解決するための手段】この課題に基づいて本発明者らは鋭意検討した結果、大豆多糖類と分岐環状デキストリンを品質改良剤として併用添加することにより、従来の方法より格段に、穀類加工食品の低温域での保存、流通、その後の喫食の為の低温域での解凍や、加熱調理に伴う食味、食感、風味、ほぐれ等の品質の劣化を改善できることを見出し、本発明を完成するに至った。
【0008】即ち、本発明は、大豆多糖類と分岐環状デキストリンを含有することを特徴とする穀類加工食品用品質改良剤であり、かつこの改良剤を添加することにより品質が改良された穀類加工食品である。
【0009】さらに本発明の内容は、原料穀類に対して大豆多糖類と分岐環状デキストリンをそれぞれ0.01〜4重量%と0.01〜4重量%含有する穀類加工食品はであり、この穀類加工食品が、低温域、即ち、0〜10℃や冷凍状態で保存される冷凍食品や冷蔵食品である。
【0010】
【発明の実施の形態】以下、本発明を詳細に説明する。本発明において大豆多糖類とは、大豆から抽出した水溶性多糖類ヘミセルロース等であり、これらの大豆多糖類としては、例えば「ソヤファイブ−S (不二製油(株)製)」が例示される。
【0011】又、本発明において分岐環状デキストリンとは、澱粉中のアミロペクチンを酵素処理することで得られる1分子内に分岐構造と環状構造を有するデキストリン化合物であり、特許文献5に記載のグルカンが相当し、「クラスターデキストリン(江崎グリコ(株)製)」として市販されているものが例示される。
【0012】原料穀類に対して、大豆多糖類は通常0.01〜4重量%、又、分岐環状デキストリンは0.01〜4重量%添加される。添加量が0.01重量%未満では効果が薄くなるので、0.01重量%以上が望ましい。又、4重量%を超えても効果はあるが、添加量が増えた分に見合う効果には至らないし、ぬるつき、ベタベタ感といった本来の穀類加工食品と懸離れた食感となり適切ではない。経済性の面からも4重量%以下がよい。ここで大豆多糖類と分岐環状デキストリンは、穀類における給水量の増大と、穀類中に吸水された水分の保持に効果があるものと考えられる。両者を併用することで相乗効果が得られ、各々の単独使用の場合と比較して、澱粉の老化が顕著に起こる低温域での穀類加工食品中の水分変化が緩慢となり、食味、食感、風味、ほぐれ等の保存性を高いレベルで維持できるものと考えられる。
【0013】本発明の好ましい態様として、本発明の穀類加工食品に更に食品用の有機酸や油脂を添加しても良い。食品用の有機酸として酢酸、乳酸、クエン酸、フマル酸、アスコルビン酸等が有り、穀類加工食品の衛生面での保存性を向上させることが出来る。食品用有機酸は原料穀類に対して0.1〜8重量%添加される。食品用の油脂としては特に限定は無いが、通常用いられる食品用の植物油等を用いるのが良く、穀類加工食品の保形性を向上させることが出来る。
食品用油脂は原料穀類に対して0.1〜8重量%添加される。従って、これらを添加することで、より新鮮な穀類加工食品に近い食感を付与できると考えられる。
【0014】本発明の穀類加工食品を製造する場合、その操作は特に限定されるものではなく、通常の製造方法を用いることが出来る。大豆多糖類と分岐環状デキストリンの添加方法は、特には限定されないが、添加の時期としては穀類加工食品の製造工程においてこれら有効成分を全体にいきわたらせる工程、及び、その前工程であることが好ましい。例えば米飯であれば米の浸漬時や炊飯時がよく、すし飯であれば寿司酢の添加時に予め寿司酢に溶解させて添加することもできる。又、麺であれば、生地の混錬時に添加し練り込む方法や、茹で汁への添加や、茹で麺に水溶液にて噴霧し麺表面に特異的に付着させる方法、パスタであれば予めパスタソースに溶解させて添加する方法も有効である。
【0015】本発明の穀類加工食品の好適な例として、冷凍状態で流通後、加熱せずに解凍する冷凍寿司や、チルド状態で流通後そのまま喫食するざるそば、割子そば、冷やしうどん等、冷凍、又は、チルド状態で流通後、電子レンジ等で加熱するピラフ、やきそば、スパゲティー、中華まん等が挙げられる。
【0016】
【実施例】以下、実施例により本発明の実施態様を説明するが、これらは例示であって制限を意図するものではない。なお、特に断らない限り例中、部及び%は何れも重量基準を意味する。

The present invention relates to improving the quality of processed cereal foods, and more particularly, to a quality improving agent for processed cereal foods which improves hogre property and flavor after storage and processed cereal foods having improved quality.
[0002]
2. Description of the Related Art Processed cereal foods such as cooked rice and noodles generally harden over time. This tendency is greater in the low temperature range below room temperature. This phenomenon is due to the aging of starch contained in processed cereal foods, which occurs because starch that has been gelatinized and swollen by water and heat is recrystallized. In addition, foods may bind to each other with cooked rice or noodles, resulting in poor greed. In particular, when the processed cereal food is distributed and stored in a low-temperature range, the quality such as taste, texture, flavor, and unraveling often deteriorates to a level that cannot withstand eating.
[0003] As a method for suppressing the above-mentioned deterioration in the quality of processed cereal foods, it is common practice to add enzymes such as α-amylase, β-amylase and glucoamylase to suppress aging of starch. Was. In addition, addition of soybean polysaccharides (Patent Documents 1 and 2), addition of reducing saccharides such as trehalose (Patent Document 3), and combined use of trehalose and soybean polysaccharides (Patent Document 4), There has been proposed an improvement method using a glucan having a cyclic or branched structure (Patent Document 5). Furthermore, a method of adding an emulsifier and fat (Patent Document 6) is also known. However, in these methods, the addition of too much of the concentration, which concentrates on the suppression of aging of starch, causes another problem such as deterioration of the taste, texture, flavor and the like of the original processed cereal food, and the effect of improvement is not achieved. At present, it is not enough and has not yet reached a satisfactory method.

[0005] In addition, processed cereal foods are often used as chilled foods or frozen foods in order to maintain hygiene and other ingredients in a period of time until eating after processing. It is stored and distributed in the low temperature range in what is said. After distribution of processed cereal foods using these additives in a low-temperature range, when eating, quality deterioration such as taste due to aging of starch occurs. There is a tendency that deterioration of quality such as taste, texture, and flavor is further caused by evaporation of water. Further, when an additive different from the flavor of the food is used, there is a problem that an unpleasant taste that is far from the original food is generated more than the deterioration of the flavor.
[0006]
DISCLOSURE OF THE INVENTION The present invention relates to processed cereal foods, especially refrigerated foods and frozen foods. After storing and distributing processed cereal foods in a low temperature range, they can be thawed in a low temperature range or reheated as they are. When cooked and eaten, including hogle, taste, texture, flavor, and the like, to provide a quality improving agent for processed cereal foods that suppresses deterioration in quality and processed cereal foods with improved quality. I do.
[0007]
Means for Solving the Problems Based on this problem, the present inventors have conducted intensive studies and as a result, by adding soybean polysaccharide and branched cyclic dextrin in combination as a quality improving agent, the cereal quality has been remarkably improved as compared with the conventional method. Preservation of processed foods in the low-temperature range, distribution, thawing in the low-temperature range for subsequent eating, and finding that it is possible to improve the deterioration of quality such as taste, texture, flavor, and looseness due to heating and cooking, and the present invention. It was completed.
[0008] That is, the present invention is a quality improving agent for processed cereal food characterized by containing soybean polysaccharide and a branched cyclic dextrin, and a cereal processing improved in quality by adding this improver. Food.
Further, the present invention is directed to a processed cereal food containing 0.01 to 4% by weight and 0.01 to 4% by weight of a soybean polysaccharide and a branched cyclic dextrin, respectively, based on the raw cereal. The processed food is a frozen food or a chilled food stored in a low temperature range, that is, 0 to 10 ° C. or a frozen state.
[0010]
BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, the present invention will be described in detail. In the present invention, the soybean polysaccharide is a water-soluble polysaccharide hemicellulose extracted from soybean, and examples of these soybean polysaccharides include "Soya Five-S (manufactured by Fuji Oil Co., Ltd.)".
In the present invention, the branched cyclic dextrin is a dextrin compound having a branched structure and a cyclic structure in one molecule obtained by enzymatically treating amylopectin in starch. Corresponding ones are commercially available as “cluster dextrins (manufactured by Ezaki Glico Co., Ltd.)”.
Usually, 0.01 to 4% by weight of soybean polysaccharide and 0.01 to 4% by weight of branched cyclic dextrin are added to the raw material cereal. If the added amount is less than 0.01% by weight, the effect is reduced, so that 0.01% by weight or more is desirable. If the amount exceeds 4% by weight, the effect is obtained, but the effect is not commensurate with the increase in the added amount, and the texture is not appropriate because it is far from the original processed cereal food such as slimy and sticky. It is preferably 4% by weight or less from the viewpoint of economy. Here, it is considered that the soybean polysaccharide and the branched cyclic dextrin are effective in increasing the water supply amount in the cereals and in retaining the water absorbed in the cereals. A synergistic effect is obtained by using both in combination, compared to the case of using each alone, the change in moisture in the processed cereal food in a low temperature range where aging of starch is remarkable occurs, taste, texture, It is considered that preservability such as flavor and looseness can be maintained at a high level.
As a preferred embodiment of the present invention, an organic acid or fat for food may be further added to the processed cereal food of the present invention. Organic acids for food include acetic acid, lactic acid, citric acid, fumaric acid, ascorbic acid, and the like, and can improve the preservability of processed cereal foods in terms of hygiene. The organic acid for food is added in an amount of 0.1 to 8% by weight based on the raw cereals. There is no particular limitation on the fats and oils for foods, but it is preferable to use vegetable oils and the like usually used for foods, and it is possible to improve the shape retention of processed cereal foods.
The fats and oils for food are added in an amount of 0.1 to 8% by weight based on the raw cereals. Therefore, it is considered that by adding these, a texture close to fresher processed cereal food can be imparted.
When producing the processed cereal food of the present invention, the operation is not particularly limited, and a usual production method can be used. The method of adding the soybean polysaccharide and the branched cyclic dextrin is not particularly limited, but the timing of the addition may be a step of spreading these active ingredients throughout the production process of the processed cereal food, and a preceding step. preferable.

(Evaluation of sushi rice)
The molded sushi rice was frozen and stored at −20 ° C. for 24 hours, and then chilled and thawed at 4 ° C. for eating. The sensory evaluation of texture was evaluated on the following three levels.
The texture is the same as that immediately after production: 3 points, which is harder than immediately after production: 2 points, which is harder to eat than immediately after production: 1 point, which is harder to maintain the molded state than immediately after production: The results are shown in Table 1 by comparing the results [Table 1]
−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−
Example 1 Three-Point Comparative Example 1 One-Point Comparative Example 2 Two-Point Comparative Example 3 0-Point Comparative Example 4 0-Point Comparative Example 5 Two-Point Comparative Example 6 Two-Point ----------------- −−−−−−−−−−−−−−−
As described above, the results of unifying the total amounts of the soybean polysaccharides and the branched cyclic dextrins or the other types of dextrins also show that the soybean polysaccharides and the branched cyclic dextrins or the other types of dextrins are unified. Compared with the case of using each of them alone, the addition of soybean polysaccharide and the branched cyclic dextrin in combination is obviously more effective in improving the texture of chilled-thawed sushi rice after frozen storage.
