Description

【０００１】
【発明の属する技術分野】
本発明は、希釈還元した時に、風味原料の本来の風味と香りを有することができる汎用凍結濃縮しらだし及びその製造方法に関する。
【０００２】
【従来の技術】
近年、本物志向の流れのなかで、ストレートつゆが販売され始め、市場にも定着してきている。
この濃縮されていないストレートつゆは、流通コストがかかるが、うどん店等の専門店のつゆと同等の香りや風味が得られるので、おいしさの点で高い評価を得ている。
一方で、従来から、製造コストや流通コストが安い濃縮つゆも販売されている。これらの濃縮つゆは価格が安い反面、希釈した時の香りや風味がストレートつゆに比べて圧倒的に劣っているという問題がある。
濃縮つゆが、ストレートつゆに比べて香りや風味の点で劣る理由は、濃縮時に香りや風味が消失してしまうことにあるため、香りや風味が消失しないように濃縮することが望まれている。
上記した濃縮時の問題点を解消する方法として、ベースとなるだし汁の抽出比を上げて始めから濃いだし汁を作る方法があるが、この方法では、抽出比率に限界があるので必要な濃度のだし汁が得られないという問題があり、また、抽出残さに多量のだし成分が残ってしまうので有効成分の廃棄の面からも問題があり、そしてなにより、希釈時の香り、風味の還元性に乏しいという欠点がある。
このため、加工食品の分野では、濃縮時に香りや風味が消失してしまわないように減圧濃縮や膜濃縮による濃縮を行っている。しかし、減圧濃縮の場合、旨みの濃縮は可能であるが、香りが濃縮時に飛散して全体のバランスが大きく崩れてしまうという問題がある。また、近年実施されている膜濃縮は、１５℃から３０℃で濃縮を行うことができるので、前記した減圧濃縮に比べて比較的低温下で濃縮を行うことができ、熱によるダメージを小さくすることができるが、この方法でも、香り成分の一部が膜を透過してしまい全体のバランスが崩れるという問題がある。
上記した濃縮時の問題を解決する方法として、魚介類や海藻類等から抽出しただしを凍結濃縮する方法及び凍結濃縮しただしを使ってつゆを作る方法が提案されている（特許文献１及び２参照）。
上記した凍結濃縮法は、非加熱の濃縮方法であり、純粋の氷をエキスの中から除去することができるので、香りや風味の損失が少ないという利点がある。

【発明が解決しようとする課題】
しかし、上記した従来の凍結濃縮だしは、だし自体の風味や香りが損失していないにもかかわらず、それを使って作ったつゆが、未だにストレートつゆに比べて風味や香りの点で劣っているという問題がある。
本発明は、上記した従来の様々な問題点を解決し、希釈還元した時に、風味原料の本来の風味と香りを有することができる汎用凍結濃縮しらだし及びその製造方法を提供することを目的としている。
【０００５】
【課題を解決するための手段】
上記した目的を達成するために、本発明に係る汎用凍結濃縮しらだしは、発酵調味料、清酒又は醤油の少なくとも一つを混合した水を溶媒として用いて風味原料からエキスを抽出した汎用しらだしを凍結濃縮してなることを特徴とするものである。
また、本発明に係る汎用凍結濃縮しらだしの製造方法は、発酵調味料、清酒又は醤油の少なくとも一つを混合した水を溶媒として用いて風味原料からエキスを抽出して汎用しらだしを生成し、前記汎用しらだしを凍結濃縮することを特徴とするものである。
上記した「汎用しらだし」は、必要に応じて味付けができるベース調味料であり、本発明に係る汎用凍結濃縮しらだしによれば、希釈前に味付けをすることにより高濃度つゆを製造することができ、また、希釈後に味付けをして目的に応じたストレートつゆを作ることもできる。
上記した風味原料としては、例えば、魚介類、畜肉類、野菜類、担子菌類、海草類が挙げられる。
海草類の一つである昆布類は、通常食用又はだし取り用として使用されるものであればよく、特にその種類は限定されることなく、また、使用する部位や形態についても限定されるものではない。
また、魚介類の一つである魚類加工品は、鰹節に代表される節類が挙げられる。ここで、節類とは、魚類を定法で加熱（一般的には煮熟）した後、ばい乾させたもの、又はその後カビ付け工程を施したものであればよく、鰹節の他に、例えば、宗田鰹節、さば節、むろあじ節、いわし節、まぐろ節、さんま節、あじ節等が挙げられるが、原料となる魚類はこれらに限定されるものではない。また、魚類加工品には、魚類を定法で加熱した後、天日や乾燥機で乾燥させた煮干類も含まれる。この煮干類については、加熱方法や乾燥方法に様々な方法があるが、その方法は限定されるものではない。
本発明においては、上記した風味原料が、一種又は二種以上の組み合わせで用いられ得る。
また、本発明においては、醤油を水に混合した溶媒を用いる場合には、醤油とだし汁とを自然感を持って馴染ませることができ、また、発酵調味料や清酒を水に混合した溶媒を用いる場合には、上記効果に加えアルコール成分により脂溶成分の抽出が可能になるが、これらを単独で水に混合するか、２種類以上を組み合わせて混合するかは、風味材料の種類や汎用しらだしの用途等に応じて適宜選択され得る。

上記した方法で得られた、本発明に係る汎用凍結濃縮しらだしと比較試料とを各々８０℃の熱湯で３倍希釈したものを、官能パネラー２０名で風味原料の香り、醤油の香り、調和感、まろやかさ、塩なれ感および総合評価について５段階評価法（５点：良好〜　不良：１点）で評価した。
表１は、評価結果であり、数値は２０名の官能パネラーの評価値の平均値を示している。
【表１】

上記した官能検査によれば本発明に係る汎用凍結濃縮しらだしは、全体的に比較試料より優れた評価が得られているが、特に、調和感、まろやかさ及び塩なれ感において比較試料より優れた評価が得られていることが分かる。
【０００９】
【実施例２】
（１）実施例１と同様の方法でみりんによる効果を確認した。抽出用の溶媒として、水９５０ｋｇ、みりん５０ｋｇを同時に抽出用タンクにて９５℃〜１００℃に加熱した後、粉砕した原料２００ｋｇを投入し、９５℃〜１００℃にて３０分間抽出した後、分離カラムで固液分離を行い、分離最終段階で抽出残さに含まれる可溶成分と溶媒を水で押し出し、回収物の全量を１０００ｋｇに調整した。これにより得られた汎用しらだしは４．２Ｂｒｉｘ％となり、官能的には風味原料の優れた香味がバランスよく包含されており、みりんとのなれ感を有した汎用しらだしが得られた。
上記した汎用しらだしを凍結濃縮して、本発明に係る１２．６Ｂｒｉｘ％の汎用凍結濃縮しらだし３００ｋｇを得た。
前記した凍結濃縮の方法は実施例１と同じく特に限定されない。
（２）抽出用の風味原料に（１）と同一のものを用い、水１０００ｋｇを抽出タンクにて９５℃〜１００℃にて加熱した後、同原料を２００ｋｇ投入して９５℃〜１００℃で３０分抽出し、その後、（１）と同様の方法で回収物を１０００ｋｇ得る。得られただし汁は３．３Ｂｒｉｘ％であり、混合した風味原料本来の香味を有していた。同だし汁を（１）と同様の方法で凍結濃縮し、３００ｋｇの凍結濃縮だし汁を得た後、同凍結濃縮だし汁に、（１）で使用したみりんを固形物換算で適量添加、調整して比較試料とした。
【００１０】
【官能検査結果】
上記した方法で得られた、本発明に係る汎用凍結濃縮しらだしと比較試料とを各々８０℃の熱湯で３倍希釈したものを、官能パネラー２０名で風味原料の香り、みりんの香り、調和感、まろやかさ、および総合評価について５段階評価法（５点：良好〜　不良：１点）で評価した。
表２は、評価結果であり、数値は２０名の官能パネラーの評価値の平均値を示している。
【表２】

上記した官能検査によれば本発明に係る汎用凍結濃縮しらだしは、全体的に比較試料より優れた評価が得られているが、特に、みりんのアルコール分により抽出された風味原料の特有の香りを有するとともに、調和感及びまろやかさおいて比較試料より優れた評価が得られていることが分かる。
【００１１】
【実施例３】
実施例１の（１）及び（２）で得られた汎用凍結濃縮しらだし及び比較試料を用いて１０倍希釈用の濃縮うどんつゆを作成した。以下にその処方を示す。また、比較対象として、９５℃〜１００℃に加熱した９４０ｇの熱水に、実施例１で使用した風味原料と同一の原料を２４ｇ投入し、３０分抽出した後、抽出残さを分離し、回収量を９４０ｇに調整しただし汁を用いてストレートうどんつゆも同時に作成した。

処方（１）及び（２）に含まれる風味原料は理論値として２４０ｇ（比率として２４％）となる。即ち、同処方の濃縮うどんつゆを１０倍に希釈しストレートつゆを仕上げた場合、２．４％重量のだし濃度となる。通常、使用されているストレートのうどんつゆのだし濃度（出来上がりに対し使用した風味原料の比率）は２〜３％が一般的であるので、上記処方（１）及び（２）では、１０倍希釈用の設計でストレートのだし濃度を再現したことになる。
【００１２】
【官能検査結果】
実際の使用場面（希釈時）での還元性を確認するために、
処方（１）で得られた試料を熱湯で１０倍希釈したもの（本発明）と、
処方（２）で得られた試料を熱湯で１０倍希釈したもの（比較試料）と、
処方（３）で得られたストレートうどんつゆを凍結濃縮せずにそのまま加熱したもの（ストレート）と
を実施例１と同じ条件の官能検査方法で検査した。
表３は、評価結果であり、数値は２０名の官能パネラーの評価値の平均値を示している。
【表３】

上記実施した官能検査から、本発明に係る汎用凍結濃縮しらだしを用いたつゆは、風味原料の香りと醤油の香りの点でそれぞれの風味についておだやかに感じられており、つゆ類のおいしさの要素である調和感、まろやかさ、塩なれ感等について、ストレートつゆ処方より優れた評価が得られた。
【００１３】
【ＧＣ−ＭＳ分析】
上記（１）本発明、（２）比較試料、（３）ストレートの３種のつゆをガスクロマトグラフ質量検出装置（ヒューレット・パッカード社製ＧＣ−ＭＳ）に供しそれぞれのつゆの香気成分を比較した。試料は喫食時の濃度にそれぞれ純水で希釈し分析に供した。
【表４】

表４中、「Ｎ．Ｄ．」は、あまりにも成分量が少ないため装置では検出できなかったことを示している。
ストレートに対する香気成分の回収量は、本発明は比較試料より醤油フェノール類、かつお節フェノール類ともにわずかに少ない。このことは、それらの物質が抽出時の反応により、他の物質へ変化したのではないかと考えられ、官能評価での風味原料の香り、醤油の香りの評価とも一致する結果であった。
【００１４】
【発明の効果】
以上説明したように、本発明に係る汎用凍結濃縮しらだしは、発酵調味料、清酒又は醤油の少なくとも一つを混合した水を溶媒として用いて風味原料からエキスを抽出した汎用しらだしを凍結濃縮してなるので、水だけで抽出していた時には得られない香りやまろやかさを持った汎用しらだしを得ることができ、かつ、それを凍結濃縮するので、得られた風味や香りを損なわないという効果を奏し、結果として、希釈前に調味料をさらに加えて高濃縮つゆを製造しても希釈時にストレートつゆに劣らぬ風味と香りを得ることができ、かつ、希釈後に調味料をさらに加えてつゆを製造してもストレートつゆに劣らぬ風味と香りを得ることができるという効果を奏する。
特に、醤油を水に混合した溶媒で風味原料からエキスを抽出することにより、エキスを抽出しただし汁と醤油とを単に配合する場合にくらべて、醤油とだし汁とをよりよく自然に馴染ませることができるという効果を奏する。
また、発酵調味料や清酒を水に混合した溶媒で風味原料からエキスを抽出することにより、アルコール成分により、水だけでは抽出できなかった脂溶成分を抽出することが可能になり、さらに、加熱抽出時に同溶媒に含まれているアルコール成分を煮切って飛散させることにより、発酵調味料や清酒の持つ特有の甘味や旨みを同時に付与することができ、まろやかでなれ感のある高濃縮つゆやストレートつゆを得ることができるという効果を奏する。[0001]
TECHNICAL FIELD OF THE INVENTION
TECHNICAL FIELD The present invention relates to a general-purpose freeze-concentrating soda that can have the original flavor and aroma of a flavor material when diluted and reduced, and a method for producing the same.
[0002]
[Prior art]
In recent years, straight soups have begun to be sold in the real-oriented trend and have become established in the market.
This unconcentrated straight soup has a high distribution cost, but has the same aroma and flavor as those of soups from specialty stores such as udon shops, and is highly evaluated in terms of taste.
On the other hand, conventionally, concentrated soups with low manufacturing costs and low distribution costs have been sold. While these concentrated soups are inexpensive, they have the problem that the aroma and flavor when diluted are overwhelmingly inferior to straight soups.
The reason why concentrated soup is inferior in fragrance and flavor compared to straight soup is that fragrance and flavor disappear when concentrated, so it is desired to concentrate so that fragrance and flavor do not disappear. .
As a method of solving the above-mentioned problem at the time of concentration, there is a method of making a thick stock from the beginning by increasing the extraction ratio of the base stock, but in this method, the stock ratio of the required concentration is limited because the extraction ratio is limited. There is a problem that it cannot be obtained, and there is also a problem in terms of disposal of the active ingredient since a large amount of soup stock remains in the extraction residue, and, above all, the aroma and dilution at the time of dilution are poor. There is a disadvantage that.
For this reason, in the field of processed foods, concentration by vacuum concentration or membrane concentration is performed so that the aroma and flavor do not disappear during concentration. However, in the case of concentration under reduced pressure, although it is possible to concentrate umami, there is a problem that the fragrance is scattered at the time of concentration and the whole balance is greatly disrupted. Further, in the membrane concentration that has been carried out in recent years, since concentration can be performed at 15 ° C. to 30 ° C., concentration can be performed at a relatively low temperature as compared with the above-described vacuum concentration, and damage due to heat can be reduced. However, even with this method, there is a problem that a part of the scent component permeates the membrane and the overall balance is lost.
As a method for solving the above-mentioned problem at the time of concentration, there have been proposed a method of extracting from fish and shellfishes and seaweeds and freeze-concentrating the same, and a method of freeze-concentrating and making a soup using the same (Patent Documents 1 and 2). reference).
The above-mentioned freeze concentration method is a non-heating concentration method and can remove pure ice from the extract, so that there is an advantage that loss of aroma and flavor is small.

[Problems to be solved by the invention]
However, the above-mentioned conventional freeze-condensed soup, although the flavor and aroma of the dashi itself are not lost, the soup made using it is still inferior in terms of flavor and aroma compared to straight soup There is a problem that there is.
An object of the present invention is to solve the above-described various problems in the related art, and to provide a general-purpose freeze-concentrating extract that can have the original flavor and aroma of a flavor material when diluted and reduced, and a method for producing the same. I have.
[0005]
[Means for Solving the Problems]
In order to achieve the above-described object, a general-purpose freeze-concentrating extract according to the present invention is a general-purpose extract obtained by extracting an extract from a flavor raw material using water mixed with at least one of a fermented seasoning, sake, and soy sauce as a solvent. Is characterized by being freeze-concentrated.
Further, the method for producing a general-purpose freeze-concentrated soda according to the present invention is to produce a general-purpose soda by extracting an extract from a flavor raw material using water mixed with at least one of fermented seasoning, sake or soy sauce as a solvent. The present invention is characterized in that the above-mentioned general-purpose soup is freeze-concentrated.
The above-mentioned `` general purpose shirazashi '' is a base seasoning that can be seasoned as required, and according to the universal freeze-concentrating shiraza according to the present invention, it is possible to produce a high-concentration soup by seasoning before dilution. It is also possible to make a straight soup according to the purpose by seasoning after dilution.
Examples of the above-mentioned flavor raw materials include seafood, livestock meat, vegetables, basidiomycetes, and seaweeds.
Kelps, one of the seaweeds, may be those usually used for edible or stocking purposes.The types are not particularly limited, and the parts and forms used are not limited. Absent.
In addition, the processed fish, which is one of the seafood, includes knots such as bonito. Here, the knots may be anything obtained by heating (generally boiled) fish and then drying the fish or subjecting the fish to a mold-making process. Bonito, soda katsuobushi, mackerel, muro-aji-bushi, sardine-bushi, tuna-bushi, sanma-bushi, and aji-bushi, but the raw material fish is not limited to these. In addition, processed fish products include boiled fish dried by heating in the sun or in a drier after heating fish by a standard method. There are various heating and drying methods for the dried dishes, but the methods are not limited.
In the present invention, the above-mentioned flavor materials may be used alone or in combination of two or more.
Further, in the present invention, when a solvent in which soy sauce is mixed with water is used, soy sauce and soup stock can be blended with a natural feeling, and a solvent in which a fermented seasoning or sake is mixed with water is used. When used, in addition to the above effects, the alcohol component enables extraction of fat-soluble components. However, whether these components are mixed with water alone or in combination of two or more types depends on the type of flavoring material and general purpose. It can be appropriately selected according to the use of the shibashi.
[0006]

Embodiment 3
A concentrated udon soup for 10-fold dilution was prepared using the general-purpose freeze-concentrated sliver obtained in (1) and (2) of Example 1 and a comparative sample. The formula is shown below. As a comparative object, 24 g of the same raw material as the flavor raw material used in Example 1 was put into 940 g of hot water heated to 95 ° C. to 100 ° C., extracted for 30 minutes, and the extraction residue was separated and collected. The amount was adjusted to 940 g, but straight udon soup was also made using juice.

The flavor material contained in the formulas (1) and (2) is 240 g (24% in ratio) as a theoretical value. That is, when the concentrated udon soup of the same formula is diluted 10-fold to finish a straight soup, the stock concentration becomes 2.4% by weight. Normally, the concentration of the soup stock of straight udon (the ratio of the used flavor ingredients to the finished product) is generally 2 to 3%. Therefore, in the above formulas (1) and (2), a 10-fold dilution is used. This means that the straight soup density was reproduced in the design for the product.
[0012]
[Sensory test results]
To confirm the reducibility in the actual use situation (dilution),
A sample obtained by formula (1) diluted 10-fold with boiling water (the present invention);
A sample obtained by formula (2) diluted 10-fold with hot water (comparative sample),
The straight udon soup obtained in the prescription (3), which was directly heated without freeze-concentration (straight), was tested by the sensory test method under the same conditions as in Example 1.
Table 3 shows the evaluation results, and the numerical values show the average of the evaluation values of the sensory panelists of 20 persons.
[Table 3]

From the sensory tests performed above, the soup using the general-purpose freeze-concentrated soy sauce according to the present invention is mildly felt for each flavor in terms of the flavor of the flavor raw material and the aroma of soy sauce, and the taste of the soup is delicious. With respect to the elements such as harmony, mellowness, and saltiness, the evaluation was superior to the straight soup formulation.

The three types of soups of (1) the present invention, (2) the comparative sample, and (3) straight were supplied to a gas chromatograph mass detector (GC-MS manufactured by Hewlett-Packard Company) to compare the odor components of each soup. Each sample was diluted with pure water to a concentration at the time of eating, and subjected to analysis.
[Table 4]

In Table 4, "ND" indicates that the component amount was too small to be detected by the apparatus.
In the present invention, the recovery amount of the fragrance component from the straight is slightly smaller in both the soy sauce phenols and the bonito phenols than in the comparative sample. This suggests that these substances may have changed to other substances due to the reaction at the time of extraction, and the result was consistent with the evaluation of the scent of the flavor material and the scent of soy sauce in the sensory evaluation.

【The invention's effect】
As described above, a general-purpose freeze-concentrating extract according to the present invention is a general-purpose extract that extracts an extract from a flavor material using water mixed with at least one of fermented seasonings, sake or soy sauce, and freeze-concentrates. As a result, it is possible to obtain a general-purpose sashimi with aroma and mellowness that cannot be obtained when only water is used for extraction, and since it is freeze-concentrated, it does not impair the flavor and scent obtained. As a result, as a result, even if a highly concentrated soup is added by adding a seasoning before dilution, a flavor and aroma that is not inferior to a straight soup can be obtained at the time of dilution, and a seasoning is further added after dilution. Even if a tetsuyu is manufactured, it has the effect of being able to obtain the same flavor and aroma as a straight soup.
In particular, by extracting the extract from the flavor ingredients with a solvent in which soy sauce is mixed with water, the extract can be extracted, but the soy sauce and the soup stock can be blended more naturally than in the case where the juice and the soy sauce are simply blended. It has the effect of being able to.
In addition, by extracting the extract from the flavor raw material with a solvent in which fermented seasoning or sake is mixed with water, it is possible to extract fat-soluble components that could not be extracted with water alone, due to the alcohol component. During extraction, the alcohol component contained in the solvent is boiled off and scattered, so that the unique sweetness and umami of fermented seasonings and sake can be added at the same time, making it a highly concentrated tsuyuya with a mellow feeling This has the effect that a straight soup can be obtained.
