Description

【0001】
【発明の属する技術分野】
本発明は、乾燥アルファ化米(白米、かゆ、五目御飯、赤飯等)、乾燥アルファ化米粉等の乾燥米飯・乾燥米飯加工品をはじめとする、乾燥穀類や乾燥穀類加工品及びその製造方法に関し、特に、保存性に優れた乾燥穀類や乾燥穀類加工品及びその製造方法に関する。
【0002】
【従来の技術】
従来より、米等の炊飯米を乾燥して得られる商品として乾燥アルファ化米、フレーク状の米粉、フリーズドライ米飯等があり、これらに調味成分や具材を添加又は添付したりしたものなどもある。また、かゆ状にしたものや、雑穀(ヒエ、キビ、粟等)等も単独又は混ぜたものなどもある。これらは、湯を加えるだけで復元することから即席的に食することができ便利である。このため、硬さや形状を変えれば、一般食としてだけでなく、乳児食、病人食、高齢者向け食品として更には保存食としても利用することができ、これらの乾燥食品は有用である。
【0003】
ところが、米等の穀類乾燥品、乾燥加工品は、本来風味が変化しやすく、またそれに含まれる油脂も酸化し易く、異臭、酸化臭の発生等が短期間で起こることが一般的である。レトルト米飯を含む炊飯した含水状態の米においてさえ風味の変化、異臭、酸化臭の問題発生が知られており、乾燥したものは乾燥工程で熱がかかる事、圧篇されたり、多孔質構造となり空気(酸素)と接触する面積が多くなり、酸化などにより風味の劣化、異臭等の発生が起こりやすくなる。これらは、遮光し密封、あるいは酸素との遮断を行えば1年以上は官能的には品質が保持できる場合もあるが、概ね商品の品質保持期間は、3〜6ヶ月である。ここで、乾燥α化米の酸化臭を防止する従来技術に、脱脂粉乳とビタミンEとを組合わせものを用いたものがある(特許文献1参照)。しかし、この技術は、実際に使用した場合には乳由来のアレルギー物質を含むことになり、ミルク臭等の問題も抱えている。

【発明が解決しようとする課題】
本発明は、長期間保存しても異臭や酸化臭の発生が無く、風味も良好であり、更にはPVの上昇も少なく、更には乳由来のアレルギー物質やミルク臭等の問題も無い、保存性良好な米などの穀類乾燥品、穀類乾燥加工品及びその製造方法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】
本発明(1)は、穀類をα化する工程と、該α化した穀類を乾燥する工程とを含む、乾燥穀類又は乾燥穀類加工品の製造方法において、該乾燥工程前に、α化した穀類に対して0.05〜5重量%の中鎖脂肪酸トリグリセライドを添加する工程を含むことを特徴とする方法である。
【0007】
また、本発明(2)は、該添加工程において、中鎖脂肪酸トリグリセライドと共に、中鎖脂肪酸トリグリセライドに対して0.01〜10重量%のビタミンEを添加する、前記発明(1)の方法である。
【0008】
更に、本発明(3)は、穀類が米である、前記発明(1)又は(2)の方法である。
【0009】
また、本発明(4)は、前記発明(1)〜(3)のいずれか一つの方法に従って製造された乾燥穀類又は乾燥穀類加工品である。
【0010】
【発明の実施の形態】
まず、本明細書で用いられている用語の意義について説明する。
【0011】
「穀類」とは、イネ科植物の種子を指し、例えば、米、ヒエ、キビ、粟等が挙げられる。米の場合、種類や部位は特に限定されず、うるち米(低アミロース米を含む)やもち米でも、また、白米でも玄米でもよい。
【0012】
「乾燥穀類」とは、穀類をα化した後に乾燥させたものをいう。例えば、いわゆるアルファ米(本明細書にいう「乾燥アルファ化米」)を挙げることができる。
【0013】
「乾燥穀類加工品」とは、穀類に手を加えた後に乾燥させたものと、乾燥穀類に手を加えたものの両方を含む概念である。前者の例としては、穀類に調味料や具材等を入れた加工品(例えば炊込み御飯)を乾燥させたもの、後者の例としては、乾燥後に乾燥した具材や調味料を加えたものや乾燥穀類を粉末化したものを挙げることができる。
【0014】
「α化」とは、β−澱粉をα−澱粉に変えることを指す。
【0015】
「中鎖脂肪酸トリグリセライド」とは、炭素数6〜12(好適には8〜10)の脂肪酸とグリセリンとのトリエステルを意味する。ここで、使用可能な脂肪酸としては、カプロン酸、カプリル酸、カプリン酸、ラウリン酸等を挙げることができる。加えて、このトリエステルを構成する3個のアシル基は、すべて同一でも、二つが同一でも、三つとも相違していてもよい。また、複数種を組み合わせて用いてもよい。なお、これは一般にMCTオイルといわれており、容易に入手可能である。
【0016】
「ビタミンE」は、α−,β−,γ−及びδ−トコフェロール並びにα−,β−,γ−及びδ−トコトリエノールのいずれかまたはこれらの組み合わせを指す。
【0017】
以下、本発明に係る乾燥穀類又は乾燥穀類加工品の製造方法につき説明する。尚、以下の説明では、穀類の一つである米について具体的に行うが、他の穀類についても当業者であれば、本明細書の記載に基づき容易に実施可能である。
【0018】
まず、本方法は、原料である米をアルファ化してアルファ化米を得る工程を含む。ここで、アルファ化させる好適な手段としては、炊飯{容器に米と水を入れ電気やガス等の熱によりご飯を炊きあげること(バッチ式)}や、上記処理乃至は蒸煮(米を金網のベルトコンベアに均一に層状に並べ、蒸気相内を連続的に流すことにより、ご飯に炊きあげること)を挙げることができる。なお、本明細書にいう「アルファ化米」とは、澱粉がアルファ化している米を意味し(例えば、炊きたてご飯)、乾燥させたものは含まない概念である。
【0019】
ここで得られたアルファ化米の水分含量は、おこわ程度の炊飯状態からお粥の炊飯水分までとするが、好適には55〜90重量%、より好適には60〜70重量%に調節する。なお、本明細書における水分含量(調湿水分量を含む)は、赤外線水分計により測定された値をいう。
【0020】
本方法は、アルファ化米を乾燥させて乾燥アルファ化米を得る工程を更に含む。乾燥工程は特に限定されず、熱風乾燥、真空乾燥、凍結乾燥、ローラー乾燥、高周波乾燥、天日乾燥等が採用しうる。但し、好適には熱風乾燥であり、具体的には、60〜100℃の温度で、1〜2時間程度の時間、乾燥させることが好適である。また、乾燥手段としては、例えば、パンド乾燥、棚式乾燥等を挙げることができる。尚、乾燥の程度であるが、アルファ澱粉の安定性、タンパク質の熱変成、乾燥変形による復元性の劣化の観点から、乾燥アルファ化米の水分含量が、1〜15%となる程度まで乾燥させることが好適である。
【0021】
そして、本発明は、乾燥工程の前に、α化米に対して0.05〜5重量%の中鎖脂肪酸トリグリセライドを添加する工程を含むことを特徴とする。ここで、乾燥工程前に添加する理由は、乾燥時に熱がかかり油脂の劣化が起こり易いためである。また、添加方法としては、炊飯後、噴霧添加する方式を採ることが挙げられる。尚、中鎖脂肪酸トリグリセライドを添加するタイミングは、乾燥工程前であれば特に限定されないが、好ましくは、アルファ化工程後乾燥工程前である。但し、均一に穀類に行き渡るために、α化工程前に添加してもよい。
【0022】
更に、該添加工程において、中鎖脂肪酸トリグリセライドとビタミンEとを組み合わせて使用することが好適である。この場合、ビタミンEの量は、中鎖脂肪酸トリグリセライドに対して0.01〜10重量%とすることが好適である。
【0023】
尚、本方法は、好適には、乾燥工程の後に、乾燥アルファ化米を焙煎して膨化乾燥アルファ化米を得る工程を含む。ここで、「膨化」とは、吸水性を上げるために、乾燥アルファ化米内部に空洞を形成させる操作をいう。本工程は、好適には120〜250℃、より好適には140〜220℃で、30〜120秒焙煎を行なう。また、復元時間、米粒組織の破壊防止、膨潤しすぎによる崩壊防止等の観点から、焙煎後の比容積(ml/g)は2〜5であることが好適である。なお、本明細書の「比容積」は、ブラウエル穀粒計により測定された値をいう。
【0024】
尚、焙煎工程の前に、必要に応じ、乾燥アルファ化米の水分量が均等になるように調整する調湿工程(テンパリング工程)を更に含んでいてもよい。特に、ハンドリングの観点からは、一度過剰に乾燥させた後(例えば、2重量%程度低め)に調湿するという手法を講じることで、乾燥アルファ化米の水分量を容易に均等にすることができるため好適である。ここで、調湿手段としては、例えば、乾燥アルファ化米をタンクに入れ、一定の高湿度・温度の空気を送風循環(対流)させることにより、徐々にゆっくりと乾燥アルファ化米の水分含量を上げる方法が挙げられる。また、調湿水分は、焙煎機の種類、能力により異なるが、7〜15重量%とすることが好ましい。
【0025】
また、アルファ化米を得る工程において、乾燥アルファ化米及び膨化アルファ化米を得る工程において、食塩、油脂、アミノ酸等の調味料、香料等添加物を添加してもよい。
【0026】

TECHNICAL FIELD OF THE INVENTION
The present invention relates to dried cereals and processed processed cereals, including dried pregelatinized rice (white rice, rice porridge, gome rice, red rice, etc.), dried preprocessed rice such as pregelatinized rice flour, and processed dried rice, and a method for producing the same. In particular, the present invention relates to a dried cereal, a processed dried cereal product having excellent storage stability, and a method for producing the same.
[0002]
[Prior art]
Conventionally, products obtained by drying cooked rice such as rice include dried pregelatinized rice, flaked rice flour, freeze-dried cooked rice, and the like, and those to which seasoning ingredients and ingredients are added or attached. is there. In addition, there are also porridges, cereals (millet, millet, millet, and the like) and the like alone or mixed. Since these are restored only by adding hot water, they can be eaten instantly and are convenient. For this reason, if the hardness and shape are changed, it can be used not only as a general food but also as a food for infants, sick people, food for the elderly, and also as a preserved food, and these dried foods are useful.
[0003]
However, dried cereal products such as rice and dried processed products are liable to change in flavor originally, and oils and fats contained therein are also easily oxidized, so that generation of off-flavor, oxidative odor and the like generally occur in a short period of time. Even in the case of cooked and wet rice, including retort cooked rice, it is known that flavor changes, off-flavors, and oxidative odors occur.Dried ones are subject to heat during the drying process, are knitted or have a porous structure. The area in contact with air (oxygen) increases, and the deterioration of flavor and the generation of off-flavor due to oxidation and the like are likely to occur. These can be functionally maintained for more than one year if they are shielded from light and sealed or shielded from oxygen, but the quality maintenance period of the product is generally 3 to 6 months. Here, as a conventional technique for preventing the oxidation odor of dried α-rice rice, there is a technique using a combination of skim milk powder and vitamin E (see Patent Document 1). However, this technique contains milk-derived allergic substances when actually used, and has problems such as milk odor.
[0004]

[0010]
BEST MODE FOR CARRYING OUT THE INVENTION
First, the meaning of the terms used in this specification will be described.
[0011]
The term “cereals” refers to seeds of grasses, and examples thereof include rice, millet, millet, millet, and the like. In the case of rice, the type and site are not particularly limited, and may be glutinous rice (including low amylose rice) or sticky rice, or may be white rice or brown rice.
[0012]
"Dried cereals" refers to cereals that have been gelatinized and then dried. For example, so-called alpha rice ("dried pregelatinized rice" as used herein) can be mentioned.
[0013]
The “processed dried cereal product” is a concept including both dried cereals after modifying the cereals, and dried cereals. Examples of the former include dried processed products (for example, cooked rice) in which cereals contain seasonings and ingredients, and examples of the latter include dried ingredients and seasonings added after drying. And dried cereals in powder form.
[0014]
"Gelatinization" refers to converting beta-starch to alpha-starch.
[0015]
“Medium chain fatty acid triglyceride” means a triester of a fatty acid having 6 to 12 (preferably 8 to 10) carbon atoms and glycerin. Here, usable fatty acids include caproic acid, caprylic acid, capric acid, lauric acid and the like. In addition, all of the three acyl groups constituting the triester may be the same, two may be the same, or all three may be different. Further, a plurality of types may be used in combination. In addition, this is generally called MCT oil and is easily available.
[0016]
“Vitamin E” refers to α-, β-, γ- and δ-tocopherol and any of α-, β-, γ- and δ-tocotrienol or a combination thereof.
[0017]
Hereinafter, a method for producing a dried cereal or a processed dried cereal product according to the present invention will be described. In the following description, rice, which is one of cereals, will be specifically described. However, other cereals can be easily implemented by those skilled in the art based on the description in this specification.
[0018]
First, the present method includes a step of pregelatinizing rice as a raw material to obtain pregelatinized rice. Here, as a suitable means for pregelatinizing rice, rice is put into a container, and rice and water are put into a container to cook rice by heat such as electricity or gas (batch type), or the above treatment or steaming (rice is put into a wire mesh). Cooked on rice by arranging them uniformly in a layer on a belt conveyor and continuously flowing in the vapor phase). The term “pregelatinized rice” as used herein means rice in which starch is pregelatinized (for example, freshly cooked rice), and is a concept that does not include dried rice.
[0019]
The water content of the pregelatinized rice obtained here ranges from the rice state of rice in a badly cooked state to the water content of rice cooked with porridge, but is preferably adjusted to 55 to 90% by weight, more preferably 60 to 70% by weight. . In addition, the water content (including the moisture control moisture content) in this specification refers to a value measured by an infrared moisture meter.
[0020]
The method further includes drying the pregelatinized rice to obtain a dry pregelatinized rice. The drying step is not particularly limited, and hot air drying, vacuum drying, freeze drying, roller drying, high frequency drying, solar drying and the like can be employed. However, it is preferably hot-air drying, and more specifically, drying at a temperature of 60 to 100 ° C. for about 1 to 2 hours. In addition, examples of the drying means include band drying and shelf drying. In addition, although it is a degree of drying, from the viewpoint of stability of alpha starch, thermal denaturation of protein, and deterioration of restorability due to drying deformation, the dried gelatinized rice is dried until the moisture content becomes 1 to 15%. Is preferred.
[0021]
And this invention is characterized by including the process of adding 0.05-5 weight% of medium chain fatty acid triglyceride with respect to gelatinization rice before a drying process. Here, the reason for adding before the drying step is that heat is applied at the time of drying and deterioration of fats and oils is likely to occur. In addition, as an addition method, a method of spray addition after cooking rice may be employed. The timing of adding the medium-chain fatty acid triglyceride is not particularly limited as long as it is before the drying step, but is preferably after the pregelatinization step and before the drying step. However, it may be added prior to the pregelatinization step in order to spread the grains uniformly.
[0022]
Further, in the addition step, it is preferable to use a medium-chain fatty acid triglyceride in combination with vitamin E. In this case, the amount of vitamin E is preferably 0.01 to 10% by weight based on the medium-chain fatty acid triglyceride.
[0023]
In addition, the method preferably includes a step of roasting the dried pregelatinized rice to obtain puffed dried pregelatinized rice after the drying step. Here, "puffing" refers to an operation of forming cavities inside dried pregelatinized rice in order to increase water absorption. In this step, roasting is preferably performed at 120 to 250 ° C, more preferably 140 to 220 ° C, for 30 to 120 seconds. From the viewpoints of restoration time, prevention of destruction of rice grain structure, prevention of collapse due to excessive swelling, and the like, the specific volume after roasting (ml / g) is preferably 2 to 5. The “specific volume” in the present specification refers to a value measured by a Brawell grain meter.
[0024]
In addition, before the roasting step, if necessary, a moisture conditioning step (tempering step) for adjusting the moisture content of the dried pregelatinized rice to be uniform may be further included. In particular, from the viewpoint of handling, it is possible to easily equalize the water content of the dried pregelatinized rice by taking a method of once drying excessively (for example, lowering about 2% by weight) and then adjusting the humidity. It is preferable because it can be performed. Here, as the humidity control means, for example, dry pregelatinized rice is put in a tank, and air having a constant high humidity and temperature is circulated by air (convection) to gradually reduce the water content of the dry pregelatinized rice. There is a method of raising. The moisture content varies depending on the type and capacity of the roaster, but is preferably 7 to 15% by weight.
[0025]
In addition, in the step of obtaining pregelatinized rice, in the step of obtaining dried pregelatinized rice and puffed pregelatinized rice, additives such as salt, oils and fats, amino acids and other seasonings, flavors and the like may be added.
[0026]
【Example】
Examples of the present invention will be described below, but the present invention is not limited to these examples.
[0027]
Example 1
First, 1000 g of rice (millie queen produced in 2001) having a rice polishing rate of 88% was dry-washed, immersed in water for 2 hours, and then cooked. And medium chain fatty acid triglyceride {O. D. O 7.8 g (0.3% by weight based on cooked rice) manufactured by Nippon Oil Co., Ltd. was directly sprayed, followed by hot air drying (70 ° C. for 1 hour). After humidification (water content 14.5%), the mixture was roasted and expanded by a fluidized roaster at 120 ° C. for 30 seconds and 150 ° C. for 30 seconds. Then, 20 g of the dried pregelatinized rice was placed in an aluminum bag, and an aluminum bag enclosing the dried pregelatinized rice was obtained while purging with nitrogen.
[0028]
Examples 2 to 4
When spraying medium-chain fatty acid triglyceride (ODO), drying was performed in the same manner as in Example 1 except that a combination of vitamin E (manufactured by Emix D Eisai Co., Ltd.) was used. An aluminum bag containing pregelatinized rice was obtained. The amount of vitamin E used was 0.625 mg% (based on dried pregelatinized rice) in Example 2, 1.25 mg% (based on dried pregelatinized rice) in Example 3, and 12.5 mg in Example 4. % (Based on dry pregelatinized rice). In addition, the moisture after moisture conditioning of Examples 2 to 4 was 13.7%, 11.8%, and 11.7%, respectively.
[0029]
Example 5
When spraying medium-chain fatty acid triglyceride (ODO), an emulsifier containing vitamin E 17.2 mg% {RIKEN E emulsion 14SP manufactured by Riken Vitamin Co., Ltd .; vitamin E content about 20%} is added, except that In the same manner as in Example 1, a dried pregelatinized rice-enclosed aluminum bag was obtained. The moisture content after the humidity control was 13.2%.
[0030]
Comparative Example 1
A dried pregelatinized rice-enclosed aluminum bag was obtained in the same manner as in Example 1 except that ODO was not sprayed. The moisture after humidity control was 11.7%.
[0031]
Evaluation Regarding Examples 1 to 5 and Comparative Example 1, the appearance and flavor (before adding water) at the start, when stored at 37 ° C. for 2 months and 4 months, and when stored at room temperature for 2 months and 4 months , After water addition) and odor (before and after water addition) were evaluated on a 5-point scale, and the POV value was measured. The results are shown in Tables 1 to 3.
