Description

【0001】
【発明の属する技術分野】
本発明は煮豆のパウチ包装体に関し、詳しくは耐熱性合成樹脂やアルミ箔製等の軟質の袋(パウチ)内に調味液の残溜をほとんど無くして含気密封(ドライパック)された煮豆のドライパック包装体に関する。
【0002】
【従来の技術】
従来より、市販の包装煮豆は、缶詰にされた水煮スタイルのものがある。このような包装煮豆は缶を開封して調味液を棄て煮豆のみを取り出してサラダの具材としたり、適宜の味付けをして惣菜として用いられている。また近年、運搬上の取扱いも容易で包装コストの安いパウチ包装された煮豆も多く提供されるようになり、中でもパウチ内に調味液汁の溜りがほとんど無いいわゆるドライパックスタイルのものが好まれ製品化されている。
【0003】
これらに関連して例えば、特公平4−65659号公報には、軟らかくて食感の良好なドライパックスタイルの煮豆の製法が記載されている。また、特開昭57−155969号公報の実施例1にはドライパックとは言い難いが煮豆の表面に高糖度のシラップが多量に付着した小豆の甘露煮の製法が提案されている。
【0004】
【発明が解決しようとする課題】
前記水煮スタイルの包装煮豆は利用価値のない調味液を含んでいるため製品の運搬及び商品価値の上で好ましくない。
また、上記特公平4−65659号公報に提案されている製法により得られるドライパックスタイルの煮豆は、適当な軟らかさを有していて食感の良いものなる点で評価できるものの、殺菌処理工程やその後の運搬、箱詰、陳列、保管時の取扱い状況等によっては、煮豆が圧潰又は変形され見栄えのしないものとなる。
【0005】
特開昭57−155969号公報の実施例1に記載の製法によるものは、小豆の甘露煮であるために、小豆表面に高糖度シラップのヌメリやベタつき感があり、小豆同士が複数粘り付いて個別に分離し難い(パラつき感がない)ものとなる。したがって、この製法によって得られる煮豆も調味液がなくパウチ内で個々の煮豆が粘り付かずに独立状態で収納されたドライパックスタイルの煮豆のパウチ包装体とは言えず、サラダの具材や味付けをして惣菜として便利に用いるには不適なものである。
本発明は以上の従来技術が有する問題を勘案してなされたもので、パウチ包装体で煮豆同士の粘り付きがなく、表面に良好な滑り感を有するため、外部からの押圧による煮豆の変形や圧潰が生じ難く、サラダの具材等に適した煮豆を得ることができる煮豆のドライパックスタイルの包装体(ドライパック包装体)を提供することを目的とする。
【0006】
【課題を解決するための手段】
すなわち、本発明煮豆のドライパック包装体は、DE値が19以下のデキストリンを含む調味液で調味付けされた煮豆をパウチに密封包装してあることを特徴とする。このような構成とすることにより、パウチ内に収納された煮豆は表面の良好な滑りを維持したものとなり、乱暴な取扱いや運搬による外部からの押圧が加わっても、パウチ内で煮豆が滑り移動するため圧潰や変形が生じ難いものとして得ることができる。
この際、調味液中のデキストリンのDE値が15以下であり、その濃度を1重量%以上としてあると煮豆表面になお一層の滑り感が与えられるのでよい。また、濃度の上限は、本発明の煮豆表面に滑り感を付与するという効果の観点からは特に制限する必要はないが、25重量%を超えると、もはや濃度上昇に伴う効果の改善が認められないため不経済的である。
【0007】
煮豆にデキストリンを含む調味液を添加する方法としては、例えば、煮豆をデキストリンを含む調味液に浸漬(どぶ漬け)する方法、煮豆表面に調味液をスプレーする方法等がある。また、煮豆を包装体に充填する際に、少量の調味液を一緒に充填する方法でもよい。
煮豆に付着させるデキストリンを含む調味液の量は、製品全体に対して0.5〜5重量%程度が好ましい。あまり多いと、煮豆がびしょ濡れの状態となりドライパックスタイルらしからぬ製品となる。また、少な過ぎると、煮豆の表面に滑り感を付与することができず、煮豆が割れたり変形したりし易くなる。
尚、本発明においてデキストリンを含む調味液とは、食塩、甘味料、香辛料その他の調味料を添加して風味を付与した調味液に限らず、単なるデキストリンの水溶液をも含むものである。
【0008】
また、パウチ内には少なくとも煮豆の5粒体積以上の含気空間を形成してあると、パウチに外部から局部的押圧力が加わっても、パウチ内で煮豆が滑り移動できる空間となり、圧潰や変形されることをさらに未然に防ぐことができるので好ましい。
【0009】
本発明におけるデキストリンは、分岐状・直鎖状の分子構造上の区別を問うことなく、さらに、還元性・非還元性の区別を問うことなく使用可能である。またデキストリンのDE値とは、一般に「DE=還元糖%/固形分%×100」の計算式で求められるデキストロース当量を示している。この際、一般にDE値が小さい場合は高分子多糖類とされており、例えば、澱粉のDE値は約0〜1、デキストリンは約2〜50程とされている。
尚、食品用原料として市販されているデキストリンには、粉末状の乾燥品と液状の水溶液品があるが、本発明における濃度は、乾燥品換算で表わした数値(重量%)である。
【0010】
また、本発明で用いられるパウチは、レトルト殺菌が可能なアルミ箔製や耐熱性合成樹脂製の袋体が適しており、その形状は偏平形状からスタンディングパウチに至るまで各種の袋体を用いることができる。また、煮豆の風味を長期間保持するためには、酸素バリア性の高いものであることが好ましい。
【0011】
以下、本発明の煮豆のドライパック包装体をその製法に基いて説明する。
本発明で上記パウチ内に充填・密封される煮豆としては、好ましくは、乾物の豆を清水中に10〜24時間程度浸漬して水戻しをして、次いでこの水戻し豆を約93〜100℃の湯(調味液でもよい)中で20〜50分程度煮込むことにより得られたものが用いられる。
このようにして得られた煮豆は、その重量が、煮豆に仕上げた段階で乾物の豆の約2.2倍になる。
【0012】
また、上記煮豆の原料豆としては、その種類は特に制限されないが、大豆、小豆、白いんげん豆(大福豆)、レッドキドニー(赤いんげん豆)、ガルバンゾ(ひよこ豆)、マローファット(緑色豆)、グレートノーザン(小ぶり白いんげん豆)の単種あるいはそれぞれを適宜混ぜ合わせた物が好適である。
また、本発明で、上記煮豆の表面に滑り感を付与し、必要に応じて味付けをするための調味液としては、清水にDE値19以下のデキストリンを添加し、さらに好ましくは食塩、グルタミン酸ソーダ、クエン酸等の調味料を目的に応じて一種又は二種以上添加し、溶解させたものが用いられる。
【0013】
而して、本発明の煮豆のドライパック包装体を製造するに際しては、前記煮豆を耐熱性合成樹脂製パウチ内に充填・密封する前に、前記調味液に数分から数十分間浸漬する。この調味液への浸漬処理により、煮豆の表面に滑り感が付与されると共に、適宜味付けがなされるものである。浸漬処理が終了したら調味液から煮豆を取り出し、液切りした後パウチ内に充填・密封する。パウチ内への煮豆の充填・密封は常法により行えばよく、パウチ充填口から煮豆を充填後、その充填口をシルバーにて熱シールする等の技法により行う。
この際、充填後パウチを密封する前にパウチ内の空気を窒素ガス等の不活性ガスで置換しておくことが好ましく、またパウチ内の含窒素空間の容積を少なくとも煮豆の5粒体積以上の大きさにするのが、煮豆の圧潰・変形を防ぐ上でより一層好ましい。
【0014】
次いで、耐熱性パウチ内に充填・密封された煮豆を加熱殺菌することによって、本発明の煮豆のドライパック包装体を得る。
本発明の煮豆のドライパック包装体の加熱殺菌は、レトルト殺菌機等を用いて100℃以上で行えばよいが、110℃〜130℃の湯中で20〜40分間程の加圧加熱殺菌を行うのが好ましい。加熱殺菌終了後、本発明の煮豆のパウチ包装体は、速やかに冷水中にて冷却され製品とされる。
【0015】
この製品は、パウチ内に調味液がほとんど残っていないドライスタイルのものとなり、パウチ内の煮豆は表面に滑り感及び光沢(照りと艶)の付与されたものとなっており、かつ煮豆同士が粘着することなく個別に分離しているので、パウチ内で煮豆が粒ごとに滑り移動し易く、外部から局部的押圧力が加わっても圧潰や変形が生じ難く、またパウチを開封して取り出し通常の煮豆として、あるいはサラダや惣菜の具として見た目も美しく用いることができる。
【0016】
以下に試験例及び実施例をあげ、本発明を更に詳しく説明する。
【試験例】

BACKGROUND OF THE INVENTION
The present invention relates to a boiled bean pouch package, and more specifically, a boiled bean that has been air-sealed (dried pack) in a soft bag (pouch) made of heat-resistant synthetic resin or aluminum foil with almost no residue of seasoning liquid remaining. The present invention relates to a dry pack package.
[0002]
[Prior art]
Conventionally, commercially available packaged boiled beans are canned in boiled style. Such packaged boiled beans are used as a side dish by opening the can, discarding the seasoning liquid and taking out only the boiled beans to make salad ingredients, or by seasoning them appropriately. In recent years, many boiled beans with pouch packaging that are easy to handle in transportation and cheap in packaging cost have been offered. Among them, the so-called dry pack style with little condiment of seasoning juice in the pouch is preferred and commercialized. Has been.
[0003]
In connection with these, for example, Japanese Patent Publication No. 4-65659 discloses a method for producing dry pack-style boiled beans that are soft and have a good texture. Further, in Example 1 of Japanese Patent Application Laid-Open No. 57-155969, there is proposed a method for producing red bean stewed with a large amount of syrup having a high sugar content on the surface of boiled beans, which is not a dry pack.
[0004]
[Problems to be solved by the invention]
The boiled boiled beans are not preferable in terms of product transportation and commercial value because they contain a seasoning liquid having no utility value.
Moreover, although the dry pack style boiled beans obtained by the manufacturing method proposed in the above Japanese Patent Publication No. 4-65659 can be evaluated in terms of having an appropriate softness and good texture, a sterilization treatment step And depending on the subsequent transportation, boxing, display, handling situation at the time of storage, etc., the boiled beans will be crushed or deformed and will not look good.
[0005]
According to the production method described in Example 1 of Japanese Patent Application Laid-Open No. 57-155969, because the bean is boiled in sweet dew, the surface of the red beans has a high sugar content of syrup and a sticky feeling, and multiple red beans stick to each other individually. It is difficult to separate (no feeling of paralysis). Therefore, the boiled beans obtained by this method also have no seasoning liquid, and the individual boiled beans are not sticky in the pouch. It is not suitable for convenient use as a side dish.
The present invention has been made in consideration of the above-described problems of the prior art, and since there is no stickiness between the boiled beans in the pouch package and the surface has a good slipping feeling, the deformation of the boiled beans due to external pressure or An object of the present invention is to provide a dry pack style package (dried pack package) of boiled beans that is less likely to be crushed and can obtain boiled beans suitable for salad ingredients.
[0006]
[Means for Solving the Problems]
That is, the dry pack package of the present invention boiled beans is characterized in that boiled beans seasoned with a seasoning liquid containing a dextrin having a DE value of 19 or less are hermetically packaged in a pouch. By adopting such a configuration, the boiled beans stored in the pouch maintain a good sliding surface, and the boiled beans slide in the pouch even when subjected to external handling due to rough handling or transportation. Therefore, it can be obtained that it is difficult for crushing and deformation to occur.
At this time, if the DE value of the dextrin in the seasoning liquid is 15 or less and the concentration is 1% by weight or more, a further slipperiness may be given to the boiled bean surface. The upper limit of the concentration is not particularly limited from the viewpoint of the effect of imparting a slipperiness to the boiled bean surface of the present invention, but when the concentration exceeds 25% by weight, the improvement of the effect due to the increase in concentration is no longer recognized. It is uneconomical because it is not.
[0007]
Examples of the method of adding a seasoning liquid containing dextrin to boiled beans include a method of immersing boiled beans in a seasoning liquid containing dextrin, a method of spraying the seasoning liquid on the surface of boiled beans, and the like. Moreover, when filling boiled beans in a package, the method of filling a small amount of seasoning liquids together may be used.
As for the quantity of the seasoning liquid containing the dextrin made to adhere to boiled beans, about 0.5 to 5 weight% is preferable with respect to the whole product. If it is too much, the boiled beans will be soaked and the product will not look like a dry pack style. On the other hand, when the amount is too small, the surface of the boiled beans cannot be given a slipping feeling, and the boiled beans are easily cracked or deformed.
In the present invention, the seasoning liquid containing dextrin is not limited to a seasoning liquid to which a salt, sweetener, spice, or other seasoning is added to give a flavor, but also includes a simple dextrin aqueous solution.
[0008]
In addition, if an aerated space of at least five boiled beans in the pouch is formed in the pouch, even if a local pressing force is applied to the pouch from the outside, it becomes a space where the boiled beans can slide and move in the pouch. It is preferable because it can be further prevented from being deformed.
[0009]
The dextrin in the present invention can be used without any distinction between branched and straight chain molecular structures, and without any distinction between reducing and non-reducing properties. Further, the DE value of dextrin generally indicates a dextrose equivalent determined by a calculation formula of “DE =% reducing sugar /% solids × 100”. At this time, generally, when the DE value is small, it is regarded as a high molecular polysaccharide. For example, the DE value of starch is about 0 to 1, and the dextrin is about 2 to 50.
Dextrins marketed as food raw materials include powdered dry products and liquid aqueous solutions, but the concentration in the present invention is a numerical value (% by weight) expressed in terms of dry products.
[0010]
In addition, the pouch used in the present invention is suitably a bag made of aluminum foil or heat-resistant synthetic resin that can be sterilized by retort. The shape of the pouch should be various from flat to standing pouch. Can do. Moreover, in order to maintain the flavor of boiled beans for a long period of time, it is preferable that it has a high oxygen barrier property.
[0011]
Hereinafter, the dry pack package of boiled beans of the present invention will be described based on the production method.
As the boiled beans filled and sealed in the pouch in the present invention, preferably, dried beans are immersed in fresh water for about 10 to 24 hours to rehydrate, and then the reconstituted beans are about 93 to 100 What was obtained by boiling for about 20 to 50 minutes in hot water (which may be a seasoning liquid) at 0 ° C. is used.
The weight of the boiled beans obtained in this way is about 2.2 times that of dried beans at the stage of boiled beans.
[0012]
In addition, the types of raw beans for the above boiled beans are not particularly limited, but soybeans, red beans, white beans (daifuku beans), red kidney (red beans), galvanzo (chickpeas), mallow fat (green beans), great A single kind of Northern (small bean) or a mixture of each of them is suitable.
Further, in the present invention, as a seasoning liquid for imparting a slipperiness to the surface of the boiled beans and seasoning as necessary, a dextrin having a DE value of 19 or less is added to fresh water, and more preferably, sodium chloride and sodium glutamate Depending on the purpose, one or two or more seasonings such as citric acid may be added and dissolved.
[0013]
Thus, when the dried pack package of boiled beans of the present invention is manufactured, the boiled beans are immersed in the seasoning liquid for several minutes to several tens of minutes before filling and sealing in the heat-resistant synthetic resin pouch. By the immersion treatment in the seasoning liquid, a slipperiness is imparted to the surface of the boiled beans and seasoned as appropriate. When the dipping process is completed, the boiled beans are taken out from the seasoning liquid, drained, and then filled and sealed in a pouch. Filling and sealing the boiled beans in the pouch may be performed by a conventional method, and after filling the boiled beans from the pouch filling port, the filling port is heat sealed with silver or the like.
At this time, it is preferable to replace the air in the pouch with an inert gas such as nitrogen gas before sealing the pouch after filling, and the volume of the nitrogen-containing space in the pouch is at least 5 grains of boiled beans or more. It is even more preferable to make the size larger in order to prevent crushing and deformation of boiled beans.
[0014]
Subsequently, the boiled beans filled and sealed in the heat-resistant pouch are sterilized by heating to obtain the dried pack package of boiled beans of the present invention.
Heat sterilization of the dried pack package of boiled beans according to the present invention may be performed at 100 ° C. or higher using a retort sterilizer or the like, but heat and sterilization for about 20 to 40 minutes in hot water at 110 ° C. to 130 ° C. Preferably it is done. After completion of the heat sterilization, the boiled bean pouch package of the present invention is quickly cooled in cold water to obtain a product.
[0015]
This product has a dry style with almost no seasoning liquid remaining in the pouch, and the boiled beans in the pouch have a slipperiness and gloss (shine and luster) on the surface. Because it is separated separately without sticking, boiled beans are easy to slide and move by grain in the pouch, and even if a local pressing force is applied from the outside, crushing and deformation hardly occur, and the pouch is opened and taken out normally It can be used beautifully as a boiled bean, or as a salad or side dish.
[0016]
Hereinafter, the present invention will be described in more detail with reference to test examples and examples.
[Test example]
1 kg of red kidney (red bean beans: dry matter) is soaked in fresh water for 15 hours, drained and then taken out, mixed with salt (25 g), citric acid (35 g), calcium chloride (45 g) and 13.5 kg of fresh water Was boiled in 100 ° C. water for 30 minutes to obtain 2.2 kg of boiled beans. This boiled bean was immersed in cold water for 30 minutes, drained, and divided into 36 equal parts to obtain about 60 g boiled bean samples.
Then, each boiled bean sample was immersed for 20 minutes in a seasoning solution (aqueous solution) containing substances having different DE values and different concentrations as shown in Table 1 below for each sample, and then drained separately. After filling an aluminum vapor deposition pouch made of synthetic resin with a capacity of 100 cc, the head space was replaced with nitrogen to form a space of 5 or more grains of boiled beans, and then the mouth was heat sealed to obtain 36 dry pack packaging bodies It was.
Next, these dry pack packages were sterilized by heating in 120 ° C hot water for 30 minutes using a high-temperature sterilizer maintained at an internal pressure of 2.5 kg / cm 2 respectively, and then cooled in 20 ° C water for 20 minutes. A sample of 36 boiled beans in a dry pack package was obtained.
[0017]
After each sample of dry pack package of boiled beans obtained is stored at room temperature (20 ° C) for 1 month, each pouch is placed on its outer surface in order to measure the difficulty of crushing and deforming by pressing the boiled beans in the pouch. 20 places were pressed with fingertips and alternately dented to give impact pressure to the boiled beans. Thereafter, the pouch was opened and the boiled beans were taken out. The crushing (cracking), deformation and texture of each boiled bean were observed and confirmed, and the results shown in Table 1 below were obtained.
