Description
【0001】
【発明の属する技術分野】
本発明は、ルー及びその製造方法、並びに該ルーを用いてなるソース、シチュー等の加工食品に関する。
【0002】
【従来の技術】
一般的にソース、シチュー等の加工食品には、小麦粉と油脂を原料とするルーが用いられる。ルーを用いずに小麦粉のみを用いたり、或いは、ルーにおいて小麦粉以外の穀粉を用いた場合には、出来上がったソース、シチュー等に粉っぽい風味がついてしまったり、またざらつく、ダマが生じるといった好ましくない食感になる場合が多い。従って、ソース、シチュー等の加工食品に適度な粘性及び香ばしさを付与させる目的で、小麦粉と油脂を使用したルーが一般的に用いられている。
【0003】
ルーを用いてソース、シチュー等の加工食品を作製する場合、口溶け感やなめらかさ、ボディー感といった食感を調整するには、添加するルーの量を調整する方法が容易であり、一般的に用いられる。ところが、この方法によると、ルーの添加量を少なくした場合、口溶け感やなめらかさは向上するが、ボディー感がなくなってしまい、水っぽく食べ応えのない食感になってしまい、更には、パンのフィリング材やトッピング材として用いることができない。一方、ルーの添加量を多くした場合、ボディー感は向上するが、口溶け感やなめらかさが失われる。すなわち、ボディー感を持ちながら、口溶け感やなめらかさを併せ持つソース、シチュー等の加工食品を、ルーの使用量の調整によって作るのは難しいのが現状である。
【0004】
上記のような従来のルーでは、更に様々な問題点が挙げられる。従来のルーを用いたソースは、ソースを作製した後冷蔵または冷凍したり、或いは殺菌のためにレトルト処理を行うと、ソースが硬くなってしまい口溶け感が著しく悪くなってしまう。また、レトルト処理前の調理工程においては、充填の都合上、加熱による粘度上昇を抑える必要があるために、充分な加熱調理を施すことができず、加熱により生じる調理感を付与することができない。
【0005】
このような問題を解決するため、ソースを作製する際に、アジピン酸架橋コーンスターチ等の架橋澱粉を添加する方法(特開平9−262077)や、膨潤抑制処理されない澱粉および加工澱粉と、架橋澱粉および温熱処理澱粉とを併用する方法(特開平11−18681)などといった、加工澱粉を添加する方法が用いられる。加工澱粉を添加することにより、ソースを作製した後冷蔵または冷凍したり、或いは殺菌のためにレトルト処理を行った後でも、なめらかで口溶け感の良いソースを得ることができる。また、レトルト処理前の調理工程において、加熱による粘度上昇を抑えることも可能であるので、加熱調理を施すことができる。しかし一方で、加工澱粉独特の好ましくない風味がついたり、またコストアップになるといった欠点がある。
【0006】
【発明が解決しようとする課題】
本発明の目的は、ソースを作製した後冷蔵または冷凍したり、或いは殺菌のためにレトルト処理を行った後でも、なめらかで口溶け感の良いソースを得ることができ、更にレトルト処理前の調理工程において、加熱による粘度上昇を抑えることができるルー及びその製造方法、並びに該ルーを用いた加工食品を提供することにある。
【0007】
【課題を解決するための手段】
本発明者らは上記課題を達成するために鋭意研究を行った結果、ルー中の澱粉に作用しやすい液晶状態の乳化剤を添加したルーを用いて、ソース等の加工食品を作製すると、ソース等の加工食品を作製した後冷蔵または冷凍したり、或いは殺菌のためにレトルト処理を行った後でも、なめらかで口溶け感の良いソースを得ることができ、更にレトルト処理前の調理工程において、加熱による粘度上昇を抑えることができることを見いだした。さらに、少なくとも一部が液晶状態の乳化剤を、焙焼する前のルー原料に添加することにより、その効果が一層高まることを見いだし、本発明を完成させるに至った。
【0008】
すなわち、本発明の第1は、小麦粉を主とする穀粉と油脂とからなるルー原料に、水に溶解または分散させて少なくとも一部が液晶状態のグリセリン脂肪酸モノエステルを添加し、加熱開始から15〜20分で品温を95〜100℃、さらに加熱開始から25〜35分で、品温を110〜120℃に昇温させ、その後一定時間撹拌しながら、温度を保つことにより焙焼してなることを特徴とするルーに関する。好ましい実施態様としては、前記少なくとも一部が液晶状態のグリセリン脂肪酸モノエステルが、水飴、ソルビトール、グリセリンの少なくとも1種を添加して水に溶解または分散させたものである上記記載のルーに関する。
【0009】
本発明の第2は、油脂を加熱溶解し、小麦粉を主とする穀粉を加えて混合物を作製し、水に溶解または分散させて少なくとも一部が液晶状態のグリセリン脂肪酸モノエステルを添加し、加熱開始から15〜20分で品温を95〜100℃、さらに加熱開始から25〜35分で、品温を110〜120℃に昇温させ、その後一定時間撹拌しながら、温度を保つことにより焙焼することを特徴とする上記記載のルーの製造方法に関する。
【0010】
本発明の第3は、上記記載のルーを用いてなる加工食品に関する。
【0011】
【発明の実施の形態】
以下に本発明のルーについて記述する。
【0012】
本発明でいうルーは、油脂と小麦粉を用いて作製したものであり、一般的な分類として、ルーブラン(roux blanc:白色ルー)、ルーブロン(roux blond:クリーム色のルウ)、ルーブラン(roux brun:褐色ルー)等が挙げられるが、何れでもよい。
【0013】
本発明における乳化剤の液晶状態とは、水溶液中にニート状もしくはゲル状に分散し、ヘキサゴナル構造、キュービック構造、ラメラ構造または逆ヘキサゴナル構造のいずれかの構造を有することをいい、ルー原料に乳化剤を添加する際、その乳化剤が前記構造を一部有していればよい。
【0014】
本発明における少なくとも一部が液晶状態の乳化剤としては、グリセリン脂肪酸モノエステルを用いる。添加量としては、ルー中の小麦粉に対して、好ましくは0.05〜5.0重量%の範囲になるように、ルーに添加するのが適当である。更に好ましくは、ルー中の小麦粉に対して、0.2〜4.0重量%である。乳化剤の添加量が0.05重量%より少ないと、加熱による粘度上昇を抑える効果が弱くなる場合がある。逆に5.0重量%より多いと、得られたソース等の加工食品に、乳化剤の好ましくない風味が感じられることがある。
【0015】
本発明のルーに用いる油脂としては、特に限定はなく、例えば、あまに油、桐油、サフラワー油、かや油、胡桃油、芥子油、向日葵油、綿実油、菜種油、大豆油、辛子油、カボック油、米糠油、胡麻油、玉蜀黍油、落花生油、オリーブ油、椿油、茶油、ひまし油、椰子油、パーム油、パーム核油、カカオ脂、シア脂、ボルネオ脂等の植物性油脂や、魚油、鯨油、牛脂、豚脂、乳脂、羊脂等の動物性油脂、これらの油脂を原料としてエステル交換したものや、硬化油、分別油、混合油などが挙げられ、これらを単独または2種以上組み合わせて用いることが出来る。
【0016】

BACKGROUND OF THE INVENTION
The present invention relates to roux and its manufacturing method, and processed foods such as sauces and stews using the roux.
[0002]
[Prior art]
In general, roux made from wheat flour and fat is used for processed foods such as sauces and stews. When only flour is used without using roux, or when flour other than flour is used in roux, the finished sauce, stew, etc. may have a powdery flavor, or it may become rough or lumpy. Often has no texture. Therefore, roux using wheat flour and fats and oils is generally used for the purpose of imparting appropriate viscosity and flavor to processed foods such as sauces and stews.
[0003]
When using roux to make processed foods such as sauces and stews, it is easy to adjust the amount of roux added to adjust the mouthfeel, smoothness and body texture. Used. However, according to this method, when the amount of roux is reduced, the feeling of melting in the mouth and smoothness is improved, but the feeling of body disappears, and the texture becomes watery and unresponsive to eating. It cannot be used as a filling material or a topping material. On the other hand, when the amount of roux is increased, the body feeling is improved, but the melted feeling and smoothness are lost. In other words, it is difficult to produce processed foods such as sauces and stews that have a body feeling but also have a melted feeling and smoothness by adjusting the amount of roux used.
[0004]
In the conventional loop as described above, there are various problems. When a sauce using a conventional roux is refrigerated or frozen after the sauce is prepared, or when a retort treatment is performed for sterilization, the sauce becomes hard and the mouth melting feeling becomes extremely worse. Moreover, in the cooking process before a retort process, since it is necessary to suppress the viscosity increase by heating for the convenience of filling, sufficient heat cooking cannot be performed and the cooking feeling produced by heating cannot be provided. .
[0005]
In order to solve such problems, a method of adding a cross-linked starch such as adipic acid cross-linked corn starch (Japanese Patent Laid-Open No. 9-262077), starch and processed starch not subjected to swelling suppression treatment, cross-linked starch and A method of adding processed starch, such as a method of using together with heat-treated starch (Japanese Patent Laid-Open No. 11-18681), is used. By adding the modified starch, it is possible to obtain a smooth and well-melted sauce even after refrigeration or freezing after producing the sauce, or after retorting for sterilization. Moreover, since it is also possible to suppress the viscosity raise by heating in the cooking process before a retort process, it can heat-cook. On the other hand, however, there are disadvantages such as an unfavorable flavor unique to the modified starch and an increase in cost.
[0006]
[Problems to be solved by the invention]
The object of the present invention is to provide a smooth and well-melted sauce even after refrigeration or freezing after preparation of the sauce, or after retort treatment for sterilization, and further a cooking process before retort treatment The purpose of the present invention is to provide a roux that can suppress an increase in viscosity due to heating, a method for producing the roux, and a processed food using the roux.
[0007]
[Means for Solving the Problems]
As a result of diligent research to achieve the above-mentioned problems, the present inventors have prepared processed foods such as sauces using roux added with an emulsifier in a liquid crystal state that easily acts on starch in roux. Even after refrigeration or freezing after preparing processed foods, or after retorting for sterilization, a smooth and mouth-melting sauce can be obtained, and in the cooking process before retorting, by heating It was found that an increase in viscosity can be suppressed. Furthermore, by adding an emulsifier at least partly in a liquid crystal state to the raw material before roasting, it has been found that the effect is further enhanced, and the present invention has been completed.
[0008]
That is, according to the first aspect of the present invention, a glycerin fatty acid monoester at least partly in a liquid crystal state is added to a roux raw material composed mainly of wheat flour and fats and oils and dissolved or dispersed in water. The product temperature is 95-100 ° C in -20 minutes, and the product temperature is raised to 110-120 ° C in 25-35 minutes from the start of heating, and then roasted by maintaining the temperature while stirring for a certain period of time. It made it relates Lou characterized by. In a preferred embodiment, the glycerol fatty acid monoester in which at least a part is in a liquid crystal state is obtained by adding or dissolving at least one of varicella, sorbitol, and glycerin to dissolve or disperse in water .
[0009]
According to the second aspect of the present invention, fats and oils are heated and dissolved, flour is mainly added to prepare a mixture, and the mixture is dissolved or dispersed in water, and at least a part of the glycerin fatty acid monoester in a liquid crystal state is added and heated. The product temperature is 95-100 ° C. in 15-20 minutes from the start, and the product temperature is raised to 110-120 ° C. in 25-35 minutes from the start of heating. It relates to a manufacturing method of the above-mentioned roux characterized by baking .
[0010]
3rd of this invention is related with the processed food which uses the above-mentioned roux.
[0011]
DETAILED DESCRIPTION OF THE INVENTION
The following is a description of the present invention.
[0012]
The roux referred to in the present invention is produced using fats and oils and wheat flour. As a general classification, roux blank (roux blank: cream roux), roux brun: Brown roux) and the like, but any may be used.
[0013]
The liquid crystal state of the emulsifier in the present invention means that it is neat or gel-dispersed in an aqueous solution and has a hexagonal structure, cubic structure, lamellar structure or reverse hexagonal structure. When adding, the emulsifier should just have a part of said structure.
[0014]
A glycerin fatty acid monoester is used as an emulsifier that is at least partially liquid crystal in the present invention. As an addition amount, it is appropriate to add to the roux so that it is preferably in the range of 0.05 to 5.0% by weight with respect to the flour in the roux. More preferably, it is 0.2-4.0 weight% with respect to the flour in a roux. When the addition amount of the emulsifier is less than 0.05% by weight, the effect of suppressing the increase in viscosity due to heating may be weakened. On the other hand, when the content is more than 5.0% by weight, an undesired flavor of the emulsifier may be felt in the obtained processed food such as sauce.
[0015]
The fats and oils used in the roux of the present invention are not particularly limited, for example, linseed oil, tung oil, safflower oil, pod oil, walnut oil, coconut oil, sunflower oil, cottonseed oil, rapeseed oil, soybean oil, pepper oil, Vegetable oils such as kabok oil, rice bran oil, sesame oil, onion oil, peanut oil, olive oil, camellia oil, tea oil, castor oil, palm oil, palm oil, palm kernel oil, cacao butter, shea fat, borneo fat, fish oil, Animal fats and oils such as whale oil, beef tallow, pork tallow, milk tallow and sheep fat, those obtained by transesterification using these fats and oils, hardened oil, fractionated oil, mixed oil, etc., are used alone or in combination Can be used.
[0016]
As wheat flour used in the roux of the present invention, raw wheat flour that has not been subjected to a treatment such as heating, or wheat flour to which enzymes, sugars, stabilizers, emulsifiers and the like are added can be used. As wheat flour, it is possible to use one or a combination of two or more kinds selected from strong flour, semi-strong flour, medium flour, and weak flour classified by the amount of gluten and protein, preferably It is desirable to use soft flour. In addition, regarding the grade of wheat flour, it is necessary to use one or a combination of two or more selected from first, second, third, and powders classified according to the ash content. It is possible to use first and second class powders. In addition to wheat flour, various starches such as corn, tapioca, potato, and sweet potato, and flour such as corn flour may be added.
[0017]
The amount of the fat and flour in the present invention is not particularly limited, but the amount of fat is preferably 40 to 200 parts by weight with respect to 100 parts by weight of the flour. More preferably, fats and oils are 50-150 weight part with respect to 100 weight part of wheat flour. When the amount of oil is less than 40 parts by weight, good viscosity as a roux may not be obtained, and smoothness may be lacking. Moreover, when there are more fats and oils than 200 weight part, the viscosity as roux may fall or the processed food obtained may become oily taste.
[0018]
According to the present invention, it is necessary to add an emulsifier at least partially in a liquid crystal state. It is preferable that the emulsifier of the present invention is dissolved or dispersed in water to at least partly be in a liquid crystal state and then cooled to form a highly viscous gel and added to the roux. In order to maintain a stable liquid crystal state, it is more preferable to add starch syrup, sorbitol, glycerin or the like. As a method of adding an emulsifier at least partially in a liquid crystal state, it may be added to roux raw material before roasting or may be added to roux after roasting. It is good to add to the raw material. In any case, it is desirable to mix well after adding an emulsifier at least partially in a liquid crystal state.
[0019]
The roux of the present invention can be produced by a general production method except that an emulsifier in a liquid crystal state is added at least partially in the production process. For example, it can be produced by the following production method. . That is, fats and oils are heated and dissolved, and flour is further added to prepare a mixture. And this mixture is roasted. That is, the product temperature is 95-100 ° C. in 15-20 minutes from the start of heating, and the product temperature is raised to 110-120 ° C. in 25-35 minutes from the start of heating, and then the temperature is maintained while stirring for a certain time. As a result, the present invention can be obtained.
[0020]
In addition, the roux of the present invention does not have any problem even if auxiliary materials such as spices and seasonings are added as necessary.
[0021]
In the present invention, using the roux of the present invention, sauces such as white sauce, demiglace sauce, curry sauce, stew such as white stew, demiglace stew, curry stew, curry used for bread filling materials and topping materials, etc. Processed foods such as paste-like compositions can be prepared. By producing the above processed food using the roux of the present invention, it is possible to obtain a processed food that is smooth and has a good mouth-melting feeling even after refrigeration or freezing, or after retorting for sterilization. Furthermore, in the cooking process before the retort treatment, an increase in viscosity due to heating can be suppressed. The amount of the roux of the present invention used in the processed food of the present invention is not particularly limited and can be appropriately selected according to the desired texture and physical properties of the intended individual processed food. The content is preferably 1 to 25% by weight, more preferably 10 to 20% by weight. There is no particular limitation on the method for producing the processed food. For example, the processed food of the present invention can be obtained by replacing the conventionally used roux with the roux of the present invention.
[0022]
For the roux of the present invention, it is presumed that the starch in roux is surrounded by the emulsifier to some extent by adding an emulsifier that is partly in a liquid crystal state that is highly reactive with starch. . Therefore, after processing processed foods such as sauces using the roux of the present invention, processing such as sauces that are smooth and well melted even after refrigeration or freezing, or after retorting for sterilization It seems that we can get food. Furthermore, in the cooking process before the retort treatment, it seems that the increase in viscosity due to heating can be suppressed.

4 points: There is no stickiness in the mouth and it melts very smoothly and quickly.
3 points: There is little stickiness in the mouth, it is easy to melt smoothly.
2 points: Stickiness is felt in the mouth, and it is slightly difficult to melt.
1 point: It sticks in the mouth for a long time and hardly melts.
<Cooking feeling>
4 points: A strong cooking feeling is given and it is very delicious.
3 points: The cooking feeling is a little strong and delicious.
2 points: The cooking feeling is weak and not very delicious.
1 point: There is no cooking feeling and the taste is different.
When the average value of evaluation of each paneler was taken, it was as shown in Table 5.
[0030]
[Table 5]
As is apparent from the results in Table 5, curry pan filling of Examples 5 to 8 using roux (Examples 1 to 4) to which an emulsifier in at least part of the liquid crystal state was added, and at least part of the liquid crystal state. When comparing the fillings for curry bread of Comparative Examples 3 to 4 using the roux (Comparative Examples 1 and 2) to which no emulsifier is added, Examples 5 to 8 clearly have excellent texture, and the filling for curry bread Since the viscosity increase during cooking was slow, cooking at a high temperature range was possible, and the cooking feeling was excellent. On the other hand, the filling for curry bread of Comparative Example 3 was clearly inferior in texture, and the viscosity during cooking of curry bread filling was so high that cooking at a high temperature range was not possible and the cooking feeling was inferior. The curry bread filling of Comparative Example 4 to which an emulsifier that is not in a liquid crystal state was added showed a slightly improved texture and cooking feeling compared to Comparative Example 3, but from the curry bread filling of Examples 5 to 8 Was clearly inferior. In the curry bread fillings of Examples 5 to 7 using roux (Examples 1 to 3) to which at least a part of the liquid crystal emulsifier was added before baking, the liquid crystal emulsifier for the flour in roux The curry filling of Example 7, which has the largest amount, is clearly superior in texture, and the viscosity increase during curry filling cooking is the slowest, so cooking at the highest temperature is possible, and also in the cooking feeling It was the best. In addition, the curry filling of Example 8 using roux (Example 4) in which an emulsifier in a liquid crystal state was added after roasting was used in roux (e.g., an emulsifier in at least a liquid crystal state was added before roasting ( The texture and cooking feeling were slightly inferior to the curry filling of Example 7 using Example 3).
[0031]
(Examples 9 to 10 and Comparative Examples 5 to 6) White sauce production 100 g of the roux obtained in Example 3, the roux obtained in Comparative Examples 1 and 2, and 50 g of the roux obtained in Example 3 Take 50 g of the roux obtained in Comparative Example 1 in a beaker, add 600 g of milk, 0.35 g of white pepper and 3.5 g of salt, and stir at 600 rpm for 5 minutes with a stirrer while maintaining the temperature at 60 ° C. did. Then, it moved to the said flat pot, and also boiled until it reached 80% of the yield, raising the product temperature to 85 degreeC and stirring, and manufactured white sauce.
[0032]
(Evaluation of white sauce)
The obtained white sauce was evaluated when (1) immediately after production and (2) after being produced, was kept in the refrigerator for 16 hours. Evaluation items were scored by 10 panelists according to the following evaluation criteria.
<Melting feeling>
4 points: There is no stickiness in the mouth and it melts quickly.
3 points: There is little stickiness in the mouth and it is easy to melt.
2 points: Stickiness is felt in the mouth, and it is slightly difficult to melt.
1 point: It sticks in the mouth for a long time and hardly melts.
<Body feeling>
4 points: Firm physical properties and strong body feeling.
3 points: Strong physical properties and a slightly strong body feeling.
2 points: Somewhat soft physical properties and weak body feeling.
1 point: Soft and loose physical properties, no body feeling.
When the average value of evaluation of each paneler was taken, it was as shown in Table 6.
[0033]
[Table 6]
As is apparent from the results in Table 6, the white sauce of Example 9 using the roux (Example 3) to which at least a part of the liquid crystal state is added and the roux to which at least a part of the liquid state is not added. Comparing the white sauces of Comparative Examples 5 to 6 using (Comparative Examples 1 and 2), Example 9 clearly had a good mouth-melting feeling, and the difference was particularly remarkable after refrigeration. On the other hand, with respect to the body feeling, Example 9 had soft physical properties and no change after refrigeration, while Comparative Examples 5 to 6 had firm physical properties and further increased body feeling after refrigeration. The white sauce of Example 10 in which the roux to which at least a part of the liquid crystal state is added and the roux to which at least a part of the liquid crystal state is not added is used in combination with the white sauce, although slightly inferior to Example 9, Body feeling was given, and the change after refrigeration was relatively small. The white sauce of Comparative Example 6 using a roux (Comparative Example 2) to which an emulsifier that is not in a liquid crystal state was added showed a slight improvement in mouth-melting feeling as compared with Comparative Example 5, but was clearer than Examples 9-10. The difference became remarkable especially after refrigeration.

【The invention's effect】
When a processed food such as sauce was prepared using a roux to which at least a part of the present invention added a liquid crystal emulsifier, the processed food was prepared and then refrigerated or frozen, or retorted for sterilization. Later, it was found that a smooth and well-melted sauce can be obtained, and in the cooking step before retort treatment, an increase in viscosity due to heating can be suppressed, and the cooking time can be lengthened to give a strong cooking feeling. Furthermore, the effect can be further enhanced by adding an emulsifier at least partially in a liquid crystal state to the raw material before roasting.
