Description

【0001】
【発明の属する技術分野】
本発明は、電子レンジで加熱するだけで、米粒の表面がパラッとしている反面、その内部がふっくらとしておいしい米飯に仕上げることができる調理用加工米に関する。
【0002】
【従来の技術】
米をα化させて得られる加工米は、電子レンジで加熱すると、粘着性が出て米粒同士が付着してほぐれ性が悪く(パラッとしておらず)、チャーハンやピラフ用として不適である。
そこで、従来より米粒同士が付着せず、表面がパラッとした米飯に調理できるように、米粒の表面に油脂やレシチンを付着させた加工米が提案されている(特開平7−308179、特開平8−266234)。
しかしながら、この提案の加工米は、電子レンジで加熱すると表面がパラッとした米飯に仕上げることはできるものの、ふっくらとしたおいしさとコク味に欠け、そのまま食しても又はチャーハンやピラフに調理しても日本人の味覚にあわないものとなる。
【0003】
【発明が解決しようとする課題】
そこで、本発明は、電子レンジで加熱するだけで、米粒の表面がパラッとしている反面、その内部がふっくらとしたおいしさをしており、しかもコク味のある米飯に仕上げることのできる調理用加工米を提供することを目的とする。
【0004】
【課題を解決するための手段】
上記課題は、
(1)米粒と卵黄油を含んだ乳化液とを包装してレトルト処理された加工米であって、その米粒の水分を56〜65%にしたことを特徴とする調理用加工米、(2)調理用加工米全体に対して卵黄油が0.1%以上含まれている(1)記載の調理用加工米、(3)含気して包装されている(1)又は(2)記載の調理用加工米、によって達成される。
【0005】
【発明の実施の形態】
以下、本発明を詳細に説明する。なお、本発明において「%」は「質量%」を、「部」は「質量部」を意味する。
本発明で調理用加工米とは、これをそのまま電子レンジや鍋による直火等により加熱することにより米飯に、或いはこれに調味料や具材を加えて上記と同じ方法で加熱することによりチャーハンやピラフに仕上げることのできる加工米をいう。
【0006】
また、卵黄油とは、卵黄液、乾燥卵黄又はこれらの加熱処理物、あるいは卵黄レシチンを抽出する際に発生する抽出残渣(脱脂卵黄)等から抽出して得られるトリグリセリドを主成分とする卵黄由来の脂質をいい、この脂質の卵黄リン脂質又はこれをリゾ化した(ホスホリパーゼA1やホスホリパーゼA2等を用いて加水分解した)リン脂質を5〜40%程度含有したものも本発明の卵黄油に含まれる。
【0007】
本発明の調理用加工米は、米粒と卵黄油を含んだ乳化液とを包装してレトルト処理されたものである。包装してレトルト処理するのを要件とするのは、包装容器に充填された米を能率的に加熱してα化し、加工米が製造できるようにすると共に、製品化したとき加工米の米粒の水分を一定に保つためである。ここで包装とは耐熱性合成樹脂、アルミ等からなる容器に米を充填・密封することをいう。また、レトルト処理とは、容器詰めした半製品を熱水式、蒸気式等のレトルトで加圧、加熱処理することをいう。加熱温度としては、100℃を超える温度で加熱するとよく、140℃以下程度で加熱するのが一般的である。
【0008】
また、レトルト処理するに当って、米粒と卵黄油を含んだ乳化液とを包装するのを要件とするのは、後述の試験例にも示すように、この要件により、はじめて電子レンジで加熱するだけで、米粒の表面がパラッとしている反面、その内部がふっくらしており、しかもコク味のある米飯になる調理用加工米が得られるからである。すなわち、このような性状を有する調理用加工米は、卵黄油に代えて大豆レシチンやショ糖脂肪酸エステル等を含んだ乳化液を使用しても得られず、さらには、乳化液の代わりに大豆レシチンや卵黄油を単に溶解させた油脂を使用しても得られないことから明らかである。
【0009】
米粒と卵黄油を含んだ乳化液を容器に充填・密封すると、容器内の米粒の表面に乳化液が付着した状態となる。そして、これをレトルト処理すると、加熱されて乳化液は分離し、その結果、米粒の表面にその分離液が付着した状態となる。
なお、乳化液に含ませる卵黄油は、後述の試験例にも示すように、調理用加工米全体に対して0.1%以上含ませると、目的の製品が得やすくなる。ただし、5.0%を超えると油っぽさの強い米飯になる傾向となるので、5.0%以下にすることが望ましい。
【0010】
さらに、本発明の調理用加工米は、米粒の水分を56〜65%にしてある。これは、後述の試験例にも示すように、その水分が56%未満であると米粒の内部がふっくらとしたおいしさの米飯にならず、また65%を超えると表面がパラッとした米飯にならず、いずれの場合も本発明の目的が達成できないからである。米粒の水分上記範囲に入れるには、原料の米の水への浸漬時間を調節したり、米と乳化液の充填比率を調節すればよい。
なお、本発明の調理加工米は、真空包装せずに含気して包装されていることが望ましい。含気していると、後述の試験例にも示すように、表面がパラッとしている反面、その内部がふっくらとした米飯になりやすい調理用加工米が得られるからである。ここで、含気とは、空気が混入して包装されている場合のほか、窒素ガス置換されている場合を含むものである。
【0011】
本発明の調理用加工米を製造するには、無処理米やα化米等の処理米からなる米粒と卵黄油を含んだ乳化液を原料とし、その米粒の水分が56〜65%になるような工程を採用しさえすれば、そのほかの工程は通常のレトルト食品の製法によればよい。
【0012】
以上述べたように、本発明の調理用加工米は、米粒と卵黄油を含んだ乳化液とを包装してレトルト処理し、かつ米粒の水分を56〜65%とするという要件により、電子レンジで加熱するだけで、米粒の表面がパラッとしている反面、その内部がふっくらとしたおいしい米飯に仕上げることができる。
内部がふっくらとしたおいしい米飯に仕上がる原理については、深く研究したわけではないが、乳化液に含ませた卵黄油と乳化液に含まれる水分がふっくらさせるのに大きく関与しているものと考えられる。
【0013】

BACKGROUND OF THE INVENTION
The present invention relates to a cooked cooked rice that can be finished into a delicious cooked rice with a fluffy inside while the surface of the rice grain is crisp only by heating in a microwave oven.
[0002]
[Prior art]
Processed rice obtained by converting rice into alpha is not suitable for fried rice or pilaf because it becomes sticky and adheres to each other when it is heated in a microwave oven.
In view of this, there has been proposed a processed rice in which oil and fat or lecithin is attached to the surface of the rice grains so that the rice grains do not adhere to each other and can be cooked on a crunchy rice surface (JP 7-308179, JP 8-266234).
However, although this proposed processed rice can be cooked into a cooked rice surface when heated in a microwave oven, it does not have a plump taste and richness and can be eaten as it is or cooked in a fried rice or pilaf It does not match Japanese taste.
[0003]
[Problems to be solved by the invention]
Therefore, the present invention is a cooking process that can be finished into a cooked rice with a rich taste while the surface of the rice grain is crisp, just by heating with a microwave oven, while the inside has a plump taste. The purpose is to provide rice.
[0004]
[Means for Solving the Problems]
The above issues
(1) Processed rice that has been retort-processed by packaging an emulsion containing rice grains and egg yolk oil, wherein the rice grains have a moisture content of 56 to 65%, (2 (1) The cooked rice for cooking according to (1), containing 0.1% or more of egg yolk oil based on the whole processed rice for cooking, (3) described in (1) or (2) packaged with aeration Of cooked rice, achieved by.
[0005]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described in detail. In the present invention, “%” means “mass%” and “part” means “part by mass”.
The cooked rice for cooking in the present invention is fried rice by heating it in the same manner as above by adding the seasoning or ingredients to the cooked rice by heating it directly with a microwave oven or a pan, etc. Or processed rice that can be finished into pilaf.
[0006]
Egg yolk oil is derived from egg yolk mainly composed of triglyceride extracted from egg yolk liquid, dried egg yolk or a heat-treated product thereof, or an extraction residue (defatted egg yolk) generated when extracting egg yolk lecithin. refers to a lipid, egg yolk oil lipid egg yolk phospholipids or which was lyso of (hydrolyzed with phospholipase a 1 or phospholipase a 2, etc.) also present invention phospholipids those containing about 5-40% include.
[0007]
The cooked rice of the present invention is obtained by packaging a rice grain and an emulsion containing egg yolk oil and retorting. The requirement for packaging and retorting is to efficiently heat the rice filled in the packaging container into alpha and produce the processed rice. This is to keep moisture constant. Here, packaging means filling and sealing rice in a container made of heat-resistant synthetic resin, aluminum or the like. Moreover, retort processing means pressurizing and heat-treating the semi-finished product with which it filled the container with retorts, such as a hot-water type and a steam type. As the heating temperature, heating is preferably performed at a temperature exceeding 100 ° C., and heating is generally performed at about 140 ° C. or less.
[0008]
In addition, it is necessary to wrap the rice grains and the emulsion containing egg yolk oil in the retort treatment, as shown in the test examples described later. This is because the surface of the grain of rice is crisp, but the inside is plump and processed rice for cooking that has a rich taste can be obtained. That is, cooked rice having such properties cannot be obtained by using an emulsion containing soybean lecithin, sucrose fatty acid ester, or the like instead of egg yolk oil, and further, soybean instead of the emulsion. It is clear from the fact that it cannot be obtained by using fats and oils in which lecithin and egg yolk oil are simply dissolved.
[0009]
When the container is filled and sealed with an emulsion containing rice grains and egg yolk oil, the emulsion is attached to the surface of the rice grains in the container. And when this is retorted, the emulsion is heated and separated, and as a result, the separated liquid adheres to the surface of the rice grains.
In addition, the egg yolk oil contained in the emulsified liquid can be easily obtained by adding 0.1% or more to the entire cooked rice as shown in the test examples described later. However, if it exceeds 5.0%, it tends to be cooked rice with a strong oiliness, so it is desirable to make it 5.0% or less.
[0010]
Furthermore, the cooked processed rice of the present invention has a rice grain moisture content of 56 to 65%. As shown in the test examples to be described later, when the water content is less than 56%, the inside of the rice grain does not become a delicious rice with a fluffy taste, and when it exceeds 65%, the surface becomes crisp. In any case, the object of the present invention cannot be achieved. In order to make the moisture content of the rice grains fall within the above range, the immersion time of the raw rice in the water may be adjusted, or the filling ratio of the rice and the emulsion may be adjusted.
In addition, it is desirable that the cooked rice of the present invention is packaged in an aerated state without vacuum packaging. This is because, when it is aerated, as shown in a test example described later, while the surface is crisp, processed rice for cooking that tends to become plump rice is obtained. Here, the air content includes not only the case where air is mixed and packaging, but also the case where nitrogen gas replacement is performed.
[0011]
In order to produce the cooked processed rice of the present invention, an emulsion containing processed rice such as untreated rice and pregelatinized rice and an egg yolk oil is used as a raw material, and the moisture of the rice grain is 56 to 65%. As long as such a process is adopted, other processes may be performed by a normal method for producing retort food.
[0012]
As described above, the cooked rice of the present invention is a microwave oven according to the requirement that the rice grains and the emulsion containing egg yolk oil are packaged and retorted, and the moisture content of the rice grains is 56 to 65%. By simply heating at, the surface of the rice grain is crisp, but you can finish it into a delicious rice with a plump interior.
The principle of making delicious rice with a plump inside is not a deep study, but it is thought that egg yolk oil contained in the emulsion and the water contained in the emulsion are greatly involved in making it plump. .
[0013]
"Example"
Next, based on an Example and a test example, it demonstrates still in detail.
Example 1
Polished polished rice (water 15%) was washed, dipped in fresh water for 2 hours, and then drained. The rice was steamed with a steamer for 3 minutes and then cooled to room temperature (20 ° C.) to obtain treated rice.
Separately, put 100 parts of fresh water into the mixer and stir, 3 parts of egg yolk oil manufactured by QP Corporation, trade name “yolk lecithin PL-30S” (yolk oil with 30% egg yolk phospholipid content) And 5 parts of salad oil in which 0.1 part of xanthan gum was dispersed, and stirring was further continued for 10 minutes to obtain an emulsion containing egg yolk oil.
Next, 120 g of the treated rice obtained in the above step and 80 g of the emulsified liquid are filled with air (residual air) in a 120 cm × 165 cm retort pouch and sealed, and this pouch is 116 ° C. in a pressurized hot water shower type retort. And then cooled to room temperature (20 ° C.) to obtain cooked processed rice (Invention 1) of the present invention.
[0014]
Example 2
For the cooking of the present invention, the same composition and steps as in Example 1 except that the product name “York Oil HF” (egg yolk oil with an egg yolk phospholipid content of 10%) manufactured by QP Corporation was used as the egg yolk oil. Processed rice (Invention 2) was obtained.
[0015]
Example 3
For the cooking of the present invention, the same composition and steps as in Example 1 except that the product name “LPL-20” (egg yolk oil with an egg yolk lysophospholipid content of 20%) manufactured by QP Corporation was used as the egg yolk oil. Processed rice (Invention 3) was obtained.
[0016]
《Comparative example》
Comparative Example 1
Comparative product 1 was obtained in the same composition and process as Example 1, except that 1 part of high-purity soybean lecithin (acetone insoluble matter 95% or more) was used instead of 3 parts of egg yolk oil.
[0017]
Comparative Example 2
Comparative product 2 was obtained in the same formulation and process as Example 1, except that 0.5 part of sucrose fatty acid ester was used instead of 3 parts of egg yolk oil.
[0018]
Comparative Example 3
Instead of the emulsified liquid, fats and oils were prepared by dissolving 20 parts of high-purity soybean lecithin (same as in Comparative Example 1) in 100 parts of salad oil.
And the treated rice same as what was obtained in Example 1 was immersed in this oil and fat, and the oil was drained, and the treated rice which adhered oil and fat to the surface of the rice grain was obtained.
Next, 130 g of this treated rice and 70 g of fresh water were filled and sealed in the same retort pouch as in Example 1, and heated and cooled under the same conditions as in Example 1 to obtain Comparative Product 3.
[0019]
Comparative Example 4
The same formulation and process as Comparative Example 3 except that 60 parts of egg yolk oil (manufactured by QP Corporation, trade name “yolk lecithin PL-30S”) was dissolved in 100 parts of salad oil instead of the emulsion. Comparative product 4 was obtained.
[0020]
《Test example》

Moreover, it can be finished to have a rich taste unique to egg yolk. Moreover, since the state of the rice grain is somewhat sticky and the plump taste is inferior when the oil and fat containing egg yolk oil is simply attached to the surface of the rice grain as in the comparative product 4, the point is to use an emulsion. I understand that.
[0023]
Test example 2
Tests were conducted to understand the relationship between the moisture content of rice grains and their properties.
Except for changing the soaking time of the glutinous rice and the filling ratio of the obtained treated rice and the emulsion, 8 kinds of cooked processed rice in which the moisture content of the rice grains was as shown in Table 2 were the same as in Example 1. Obtained.
