Description

本発明は、加熱調理器具に関する。   The present invention relates to a cooking device.

鍋物の際、肉や魚介類を鍋に入れると、アクが鍋の煮汁上に浮かんでくる。このアクは、肉や魚介類から煮汁に溶け出したタンパク質や血液が凝固したもので、食しても人体に悪影響を与えるものではない。
しかし、アクが多量に浮かんだ状態では、見栄えが悪く、また、舌触りがよくないなどの問題がある。
When you put the meat and seafood in the pot, the ak floats on the sauce. This acupuncture is a solidified protein or blood that has been dissolved in the broth from meat and seafood, and does not adversely affect the human body even if eaten.
However, there are problems such as poor appearance and poor touch when the ak is floating in a large amount.

そこで、鍋物料理においては、一般的におたまやアク取り網等で煮汁の上に浮いたアクを取るようにしている。
また、煮汁の上に浮かべて、アクを吸着除去できるようにしたアク取りシートも提案されている(特許文献1)。
Therefore, in hot pot dishes, generally, the fish floated on the broth is taken with a ladle or a catch net.
In addition, there has also been proposed an action removing sheet that floats on the broth so that the action can be removed by adsorption (Patent Document 1).

特開2015-226695号公報JP-A-2015-226695

しかし、アク取りシートは、コンロで煮物を調理する場合には有効であるが、鍋物の場合、鍋を囲んだ人が直接鍋から調理された具材を箸などで取り出して食するようになっているため、邪魔になるという欠点がある。
また、おたまやアク取り網によってアク取りを行う場合においても、テーブルの上におたまやアク取り網を置くスペースを確保しなくてはならず、邪魔である。
However, the action removal sheet is effective when cooking boiled food on a stove, but in the case of a pot, the person who surrounds the pot takes out the ingredients cooked directly from the pot with chopsticks and eats them. Therefore, there is a drawback of getting in the way.
In addition, even when taking action by using a ladle or a catching net, a space for placing the ladle or the catching net on the table must be secured, which is in the way.

しかも、アクには、アミノ酸やミネラルなどのうまみ成分が含まれているため、取り過ぎると、鍋物の煮汁のうまみに却って悪影響を及ぼす恐れがある。   Moreover, since aqua contains umami ingredients such as amino acids and minerals, if it is taken too much, it may adversely affect the umami of the broth in the pot.

そこで、本発明の発明者は、調理時にアクの発生を抑えることができれば、アクを取り除く手間がなくなるとともに、うまみが肉や魚介類から抜け出ることが少なくなり、おいしい鍋物を食せるのではないかと考え、鋭意検討を重ね、本発明を完成するに到った。   Therefore, if the inventor of the present invention can suppress the occurrence of acupuncture during cooking, there will be no need to remove the acupuncture, and umami will be less likely to escape from meat and seafood, so that a delicious pot can be eaten. The present invention has been completed through thought and diligence.

本発明は、上記事情に鑑みて、アクの発生を抑制することができる加熱調理器具を提供することを目的としている。   In view of the above circumstances, an object of the present invention is to provide a cooking device that can suppress the occurrence of acupuncture.

上記目的を達成するために、本発明にかかる加熱調理器具は、少なくとも調理面が硬質陽極酸化アルミニウム層(硬質アルマイト層)で形成された加熱調理器具であって、硬質陽極酸化アルミニウム層が、銀化合物またはニッケル化合物で封孔されていることを特徴としている。   In order to achieve the above object, a cooking device according to the present invention is a cooking device in which at least a cooking surface is formed of a hard anodized aluminum layer (hard anodized layer), and the hard anodized aluminum layer is made of silver. It is characterized by being sealed with a compound or a nickel compound.

本発明において、加熱調理器具とは、鍋、フライパン、調理板などが挙げられる。
本発明において、調理面とは、加熱調理する食材や煮汁等が直接接する面を意味する。
In the present invention, the cooking device includes a pan, a frying pan, a cooking plate, and the like.
In this invention, a cooking surface means the surface which the foodstuffs, soup, etc. which heat cook directly contact | connect.

本発明において、銀化合物で封孔する方法としては、特に限定されないが、たとえば、KAgF4などの銀錯体溶液中で処理して酸化銀で封孔する方法が挙げられる。
また、ニッケル化合物で封孔する方法としては、特に限定されないが、たとえば、酢酸ニッケル溶液で封孔処理する方法が挙げられる。
In the present invention, the method of sealing with a silver compound is not particularly limited, and examples thereof include a method of processing in a silver complex solution such as KAgF 4 and sealing with silver oxide.
In addition, the method for sealing with a nickel compound is not particularly limited, and examples thereof include a method for sealing with a nickel acetate solution.

硬質陽極酸化アルミニウム層の厚さは、特に限定されないが、30μm〜60μmが好ましく、40μm〜45μmがより好ましい。   Although the thickness of a hard anodized aluminum layer is not specifically limited, 30 micrometers-60 micrometers are preferable, and 40 micrometers-45 micrometers are more preferable.

本発明にかかる 以上のように、少なくとも調理面が硬質陽極酸化アルミニウム層で形成された加熱調理器具であって、硬質陽極酸化アルミニウム層が、銀化合物またはニッケル化合物で封孔されているので、硬質陽極酸化アルミニウム層から遠赤外線だけでなく、銀化合物からも遠赤外線が調理器具内で調理される食材に照射され、肉汁が煮汁内に溶け出す前に肉が迅速に加熱され、外部に溶け出さずに肉片の内部にアクとなるタンパク質やうまみ成分等が肉片内に閉じ込められると考えられる。
また、硬質陽極酸化アルミニウムは、アルミニウムより熱伝導性に劣るが、銀化合物またはニッケル化合物によって封孔されているため、他の金属化合物からなる封孔処理剤を用いた硬質陽極酸化アルミニウムに比べ熱伝導性がよく、加熱調理時間を短縮することができる。
As described above, at least the cooking surface is a cooking device formed with a hard anodized aluminum layer, and the hard anodized aluminum layer is sealed with a silver compound or a nickel compound. The far-infrared rays from the anodized aluminum layer as well as the far-infrared rays from the silver compound are irradiated to the ingredients to be cooked in the cooking utensil, and the meat is rapidly heated before the meat juice is melted into the broth, and is melted to the outside. It is thought that protein and umami components that become active in the meat piece are confined in the meat piece.
Hard anodized aluminum is inferior in thermal conductivity to aluminum, but is sealed with a silver compound or nickel compound, so it is more heat-resistant than hard anodized aluminum using a sealing agent made of other metal compounds. Conductivity is good and cooking time can be shortened.

図1に示すように、この鍋1は、肉厚4mmの両手鍋であって、図2に示すように、アルミニウム製の肉厚4mmの本体2の表面を覆うように厚みが40μmの硬質陽極酸化アルミニウム層3が設けられている。
硬質陽極酸化アルミニウム層3は、本体2の表面を陽極酸化処理して形成されていて、表面の細孔31が、酸化銀32によって封孔されている。
そして、本体2の肉厚が、4mmで、硬質陽極酸化アルミニウム層3の厚みが40μmである。
As shown in FIG. 1, this pan 1 is a double-handed pan having a thickness of 4 mm, and as shown in FIG. 2, a hard anode having a thickness of 40 μm so as to cover the surface of the main body 2 made of aluminum with a thickness of 4 mm. An aluminum oxide layer 3 is provided.
The hard anodized aluminum layer 3 is formed by anodizing the surface of the main body 2, and the pores 31 on the surface are sealed with silver oxide 32.
And the thickness of the main body 2 is 4 mm, and the thickness of the hard anodized aluminum layer 3 is 40 μm.

つぎに、上記鍋1と、通常の市販アルマイト鍋(以下、「Al鍋」と記す)について、それぞれアクの発生の有無を以下のようにして調べた。
(実験1)
上記鍋1と、Al鍋のそれぞれに2000mlの水を入れて、各鍋の底中央の底から20mm上方に先端がくるように温度計を設置し、鍋内の水温を測定しながら、カセットボンベ式ガスコンロを用いて100℃まで水を加熱した。
水温が100℃に達したのち、市販のパック詰め切り落とし牛肉を、両鍋に200gずつを投入し、2分後の鍋の水に浮いたアクを目視で確認したところ、本願発明の鍋1の場合、アクが少量で白色をしていたのに対し、Al鍋の場合、鍋の表面の半分以上が牛肉内からでた血液や淡白質が固まったものと思われる茶色いアクで覆われた状態になった。 上記実験1から、本願発明の鍋1を用いれば、アルミニウム鍋に比べアクの発生が少なく、また、牛肉からうまみ成分が溶け出ることがなく、牛肉を煮ることができることがわかった。
Next, the presence or absence of occurrence of ax was examined for the pan 1 and a normal commercially available alumite pan (hereinafter referred to as “Al pan”) as follows.
(Experiment 1)
Place 2000 ml of water into each of the pan 1 and the Al pan, install a thermometer so that the tip is 20 mm above the bottom center of each pan, measure the water temperature in the pan, Water was heated to 100 ° C. using a gas stove.
After the water temperature reached 100 ° C., 200 g of each of the commercially-packed cut-off beef was put into both pans, and the acupuncture floating in the pan water after 2 minutes was visually confirmed. In the case of Al pan, in the case of Al pan, more than half of the surface of the pan was covered with brown acupuncture that seems to have solidified blood and white matter from inside the beef. Became. From Experiment 1 above, it was found that if the pan 1 of the present invention is used, the occurrence of acupuncture is less than that of the aluminum pan, and the umami component does not melt from the beef, and the beef can be boiled.

(実験2)
上記鍋1と、上記Al鍋のそれぞれに2000mlずつ、水を入れて、それぞれガスコンロに載せるとともに、鍋の底中央の底から20mm上方に先端がくるように熱伝対を設置した状態で、点火前の水温を測定するとともに、点火後100℃になるまでの時間を6回ずつ測定し、途中の50℃、80℃、90℃、95℃に到達した時間とともに、以下の表1〜表6に示した。
(Experiment 2)
In each of the pan 1 and the Al pan, add 2000 ml of water, place each on a gas stove, and set the thermocouple so that the tip is 20 mm above the bottom center of the pan. The previous water temperature was measured, and the time until the temperature reached 100 ° C. after ignition was measured 6 times, and the time when the temperature reached 50 ° C., 80 ° C., 90 ° C., and 95 ° C. along the way was shown in Tables 1 to 6 below. It was shown to.

上記表1〜表6から本願発明の鍋の方が、熱効率がよいことがわかる。 From Table 1 to Table 6, it can be seen that the pan of the present invention has better thermal efficiency.

(実験3)
縦100mm×横100mm×厚み4mmのアルミニウム板材を陽極酸化処理して40μmの硬質陽極酸化アルミニウム層を形成するとともに、酸化銀で封孔してサンプル板材Aを得た。
また、陽極酸化処理前の上記アルミニウム板材をサンプル板材Bとした。
(Experiment 3)
An aluminum plate having a length of 100 mm, a width of 100 mm, and a thickness of 4 mm was anodized to form a 40 μm hard anodized aluminum layer and sealed with silver oxide to obtain a sample plate A.
The aluminum plate material before the anodizing treatment was used as a sample plate material B.

そして、サンプル板材A,Bの室温でのサンプル板材A,B各部の表面温度を、赤外線サーモグラフィーを用いてそれぞれ測定し、その結果を表7に示した。
続いて、赤外線ランプヒーターを用いてサンプル板材A,Bの表面温度が、 ℃になるまでサンプル板材A,Bを加熱したのち、赤外線ランプヒーターの加熱を停止し、加熱停止から5分後のサンプル板材A,B各部の表面温度を、赤外線サーモグラフィーを用いてそれぞれ測定し、その結果を表7に合わせて示した。
The surface temperatures of the sample plate materials A and B at room temperature of the sample plate materials A and B were measured using infrared thermography, and the results are shown in Table 7.
Subsequently, after heating the sample plates A and B using an infrared lamp heater until the surface temperature of the sample plates A and B reaches 0 ° C., the heating of the infrared lamp heater is stopped, and the sample 5 minutes after the heating is stopped The surface temperature of each part of the plate materials A and B was measured using infrared thermography, and the results are shown in Table 7.

また、図3に加熱完了5分後のサンプル板Aの赤外線サーモグラフィーの画像の模式図を、図4にサンプル板Bの赤外線サーモグラフィーの画像を図4に示した。
図3および図4において、グレーに見える部分は、温度が高い部分で、白い部分は室温程度の低い温度である。
図3に示すように、サンプル板Aの場合、加熱完了5分後においても、表面全体が高い温度(図3では全体がグレー)に維持されるのに対し、サンプル板Bの場合、部分的に温度が高い部分が残るものの、大部分は室温程度まで温度が下がっていた。
3 shows a schematic diagram of an infrared thermography image of the sample plate A 5 minutes after completion of heating, and FIG. 4 shows an infrared thermography image of the sample plate B in FIG.
In FIGS. 3 and 4, a gray portion is a high temperature portion, and a white portion is a low temperature of about room temperature.
As shown in FIG. 3, in the case of the sample plate A, even after 5 minutes from the completion of heating, the entire surface is maintained at a high temperature (in FIG. 3, the whole is gray). However, most of the temperature was lowered to about room temperature.

上記表7、図3および図4から、サンプル板Aの方が、表面からの放熱が少ないことがよくわかる。
すなわち、本発明の加熱調理器具のように調理面に銀化合物またはニッケル化合物で封孔された硬質陽極酸化アルミニウム層を設ければ、調理面に接した状態の食材を効率よく加熱できることがわかる。
From Table 7, FIG. 3 and FIG. 4, it can be seen that the sample plate A has less heat radiation from the surface.
That is, it can be seen that if the hard anodized aluminum layer sealed with a silver compound or a nickel compound is provided on the cooking surface like the cooking device of the present invention, the food in contact with the cooking surface can be efficiently heated.

つぎに。日本電子(株)製JIR−E500型、フーリエ変換赤外分光光度計を用い、以下の測定条件で、上記鍋1および上記Al鍋のそれぞれについて、波長別に分光放射率(Emissivity)と、放射度(Radiance)を求め、サンプル板Aの分光放射率を図5に、サンプル板Aの放射度を黒体の放射度を比較して図6に、サンプル板Bの分光放射率を図7に、サンプル板Bの放射輝度黒体の放射輝度を比較して図8に示した。   Next.
