Description

【0001】
【発明の属する技術分野】
本発明は穀類加工食品の品質改良に関するものであり、詳しくは、米飯類、麺類等の穀類加工食品のホグレ性等の品質を改良する品質改良剤、およびこの改良剤を用いることにより品質の改良された穀類加工食品に関する。
【0002】
【従来の技術】
近年の食の多様化により、加工食品のニーズが増大している。特に米飯、麺といった穀類食品は、大量に加工・調理された製品が、コンビニエンスストア、スーパーマーケットなどで販売され、多くの消費者に食されるようになってきた。
【0003】これら流通・市販される加工食品において、特に問題となるのが加工の利便性と時間の経過による品質劣化である。
【0004】米飯・麺等穀類加工食品は一般に澱粉を含んでおり、加工・調理の際、食品表面に澱粉質が流出し、食品同士が結着してしまう。その結果、加工時に団子状になったり、潰れてしまったりと、加工適性に問題を生じる。具体的に例をあげると、米飯製品の場合、チャーハンで全体が均一に炒められなかったり、おにぎりの成型機で飯粒がつぶれてしまうということが起こる。また、麺製品であれば、麺同士の付着により、一食分に小分けすることが困難になる。こういった問題は、生産効率の低下、コストアップを招き、さらに、できあがった食品も喫食事に食べ辛かったり美味しくないという結果を招く。
【0005】この食品同士の結着性をなくし、ほぐれ性を改善する従来の方法としては、油脂または乳化油脂を混合する方法(特許文献1)、HLBの高いショ糖脂肪酸エステルを添加する方法(特許文献2)、有機酸を添加する方法(特許文献3)、機械的な振動を与えながら加工する方法、水溶性ヘミセルロースを使用する方法(特許文献4)などがある。

【0007】しかしながら上記の従来法では、ホグレ効果の効率、風味への影響、和洋どんなタイプの加工食品にも対応できる、米飯の場合光沢を良くする等種々のニーズに対し充分に応えられておらず、加工食品の急速な発展と普及と共に、さらに効率化、高品質化を実現する品質改良剤、および品質が改良された加工食品が求められてきており、これらの方法よりも効果的なほぐれ性の改善方法が求められるようになってきた。
【0008】また、最近油脂、水溶性ヘミセルロース、乳化剤を含有する加工米飯用改良剤も提案されている。(特許文献5)しかしこの方法は油脂の添加を必須としており、炒飯用としてはともかく、和風の食品には用い辛いものである。

【発明が解決しようとする課題】
本発明は、保存においてホグレが悪くなるなどの品質低下を抑制し、効率的に美味しい穀類加工食品を製造する為の品質改良剤及びその品質改良剤を使用した穀類加工食品を提供することを目的とした。
【0011】
【課題を解決するための手段】
本発明者らは、上記の課題に鑑み、鋭意研究を重ねた結果、水溶性ヘミセルロースと酢酸モノグリセリドを併用した穀類加工食品用品質改良剤が顕著な効果があることを見出し、本発明を完成するに至った。
【0012】すなわち本発明は、水溶性ヘミセルロース及び酢酸モノグリセリドを含むことを特徴とする穀類加工食品用品質改良剤であり、またその品質改良剤を添加又は該品質改良剤で表面処理して得られる穀類加工食品である。
【0013】本発明においては上記品質改良剤の添加量を穀類加工食品に対して、水溶性へミセルロースとして0.01%〜20%、酢酸モノグリセリドとして0.001%〜5%を添加する。そして本発明に用いられる水溶性へミセルロースとしては大豆由来の物が好ましい。
【0014】
【発明の実施の形態】
本発明の穀類加工食品とは、穀類食品(米、小麦、大麦、稗、粟等)を1次加工又は更に2次加工した食品のことをいう。1次加工食品としては米飯、麦飯、粟餅、乾麺、生麺、パスタ等があり、2次加工食品としては一次加工食品を再調理した食品、例えば、おにぎり、寿司、ピラフ、チャーハン、炊き込みご飯、混ぜご飯、そば、うどん、中華麺、パスタ、素麺等がある。
【0015】これらの穀類加工食品には、家庭で調理されるものを始めその場で食べることを目的とする最終商品型の加工食品や食べる際に調理の必要な半製品が含まれ、常温、冷蔵、冷凍、氷温等の方法で市場に流通している食品が含まれる。
【0016】また、ヘミセルロースとは、植物の細胞壁に含まれる多糖類のうち、希アルカリによって抽出されるものであり、水溶性であることが多く、酸により容易に加水分解される性質を有するものである。ヘミセルロースは構造的にも化学的性質もセルロースと類似しており、その分子量はセルロースと比べて低く、重合度約150前後の重合度の異なる分子の混合物である。本発明では、このヘミセルロースのうち水溶性のものを使用する。
【0017】本発明の水溶性ヘミセルロースは、油糧種子(パーム、椰子、コーン、綿実等)または穀類(米、小麦等)や豆類(大豆、小豆、エンドウ豆等)を原料として得られるが、溶解性や工業性の面から、豆類由来、特に大豆、なかでも子葉由来のものが好ましい。
【0018】本品質改良剤を穀類食品又は穀類加工食品に添加又は表面処理する方法は特に限定されないが、次のような方法がある。(1)加工米飯を作る場合、予め水洗した後の米に添加して炊飯する。また、その米飯を更に加工する。(2)麺又はパスタを茹でる際の水又は熱湯に予め添加して茹でる。(3)炊飯、蒸煮後の米飯や茹で上がった麺又はパスタに本品質改良剤の水溶液を絡ませて表面処理する。(4)蒸煮後の米飯や茹で上がった麺又はパスタに本品質改良剤の水溶液を噴霧する。(5)予め調味液に本品質改良剤を溶解しておき、パスタ、麺又は飯にまぶして表面処理する。(6)本品質改良剤を粉末調味料と混合し、飯、パスタ、麺にまぶして表面処理する。(7)本品質改良剤を調味料麺又はパスタ生地に添加して練り込む等である。これらの方法は製造ライン、販売形態等の個々の食品特性により選択される。
【0019】本発明において用いられる酢酸モノグリセリドは、アセチンファットとも呼ばれる親油性の高い有機酸モノグリセリドであり、通常油脂とトリアセチンとをエステル交換するか、モノグリセリドに無水酢酸を反応させ、未反応物を除去して得られる。
【0020】酢酸モノグリセリドの脂肪酸の炭素数については、特に限定はないが、通常には炭素数8から18のものが使用される。
【0021】乳化剤について言えば、本発明の酢酸モノグリ以外の乳化剤を用いても、ホグレに対する効果はかなり得られる。しかし実用的に考えると酢酸モノグリを用いずに他の乳化剤例えばレシチンやシュガーエステルを水溶性多糖類と併用すると、この2つの成分が相互作用を起こし、米飯等への処理が困難となる。酢酸モノグリは乳化剤と言われるものの中でも多糖類との併用で優れた効果を表しかつ、実用的にも扱い易い特徴を有する。
【0022】本品質改良剤の形態は、特に限定されない。例えば、水に水溶性へミセルロース、酢酸モノグリセリド、その他の副剤を溶解した液体の状態、単にこれらを混合した粉末状のもの、さらに混合したものを増粒した顆粒状のものが例示される。
【0023】本品質改良剤の好ましい添加量は、その形状、おのおのの物質の配合量に大きく影響されるので一義的には規定し難いが、通常穀類食品又は穀類加工食品に対して水溶性へミセルロースが0.01%〜20%、酢酸モノグリセリドが0.001%〜5%(重量%以下同じ)であれば良く、より好ましくは水溶性ヘミロースが0.05〜5%、酢酸モノグリセリドが0.005%〜2%である。
【0024】本品質改良剤の水溶性へミセルロース、酢酸モノグリセリドの配合比率は水溶性へミセルロース:酢酸モノグリセリドが、100:1〜1:100の範囲が適当であり、より好ましくは50:1から1:20の範囲である。
【0025】本品質改良剤には、水溶性ヘミセルロースと酢酸モノグリセリドを配合することが必須であるが、適宜、他の添加剤と併用することができる。他の添加剤としては、レシチンやグリセリン脂肪酸エステル、蔗糖脂肪酸エステル、ソルビタン脂肪酸エステル等の乳化剤、或いは一般の動植物性油脂や脂溶性ビタミンであるトコフェロール等の油性物質、蔗糖、マルト─ス、トレハロ─ス等の糖質、及び糖アルコ─ル、デキストリン、布海苔、寒天、カラギーナン、ファーセレラン、タマリンド種子多糖類、タラガム、カラヤガム、ペクチン、キサンタンガム、アルギン酸ナトリウム、トガントガム、グワーガム、ローカストビーンガム、プルラン、ジェランガム、アラビアガム、ヒアルロン酸、シクロデキストリン、キトサン、カルボキシメチルセルロース(CMC)、アルギン酸プロピレングリコールエステル、加工澱粉など各種澱粉類等の多糖類やこれら多糖類の加水分解物、ゼラチン、ホエー等のアルブミン、カゼインナトリウム、可溶性コラーゲン、卵白、卵黄末、大豆蛋白等の蛋白性物質や、カルシウム強化剤等の塩類、酢酸ソーダ等のpH調整剤が挙げられる。
【0026】本品質改良剤は、粉末状態は勿論のこと、油脂との乳化状態または懸濁状態、あるいは水、食塩水等の溶液として、さらには酢酸等の有機酸溶液に添加した溶液の状態で流通販売することができる。
【0027】本品質改良剤の穀類加工食品ヘの品質改良効果としては、その食品のホグレが良くなり麺線や飯粒の結着がなくなり、食べる際に食べ易い、おいしいと感じることが挙げられる。また製造工程において、混ぜやすい、潰れにくいといった加工適正が付与されることも大きな効果である。例えば、コンビニエンスストアで販売される寿司を例にとると次のような効果が得られる。炊飯時に本改良製剤を添加して炊飯しておくと、炊飯後のほぐし工程において、飯が塊にならず、混ぜやすく、飯粒がつぶれない。成型機にかけた場合、飯粒が潰れないので不良品が少なく、製品歩留まりがアップする。また、成型機を洗浄する頻度が少なくなる。従来、これらの現象を防止する為、炊飯油を使用していたが、風味の点では決して好ましくない。本品質改良剤を使用した場合、炊飯油を無添加もしくは添加量を低減することができる。
【0028】この他に本品質改良剤を添加又は表面処理した穀類加工品の特徴及び効果としては、ぱさつき感がなく、表面の光沢が維持されること、麺質および飯質の低下が少なく、長期の保存においても効果が持続されること、油分を添加したときにみられる油浮きがなく、和風の食品にも使用しやすいこと、添加方法が簡単なため特別な設備を必要としないことなどがあげられる。
【0029】
【実施例】以下、実施例を挙げて本発明をさらに説明するが、本発明はこれらの例示によって制限されるものではない。なお、例中の部および%は何れも重量基準を意味する。
【0030】以下に示す実施例おいて水溶性ヘミセルロースは、「ソヤファイブーS」(不二製油(株)製)として市販されている水溶性大豆ヘミセルロースを使用した。また、酢酸モノグリセリドは、市販されている「アセテム95CO」(ダニスコ社製)を用いた。
【0031】上記の水溶性へミセルロース10部、酢酸モノグリセリド1.0部を水89部に投入し、70℃で10分間溶解後、121℃で10分間レトルト殺菌し、品質改良剤Aを得た。

【0036】表2の結果より、水溶性へミセルロースと酢酸モノグリセリドを適量添加したテスト区4の評価が良好であった。酢酸モノグリセリド単独使用であるテスト区2では効果が認められず、テスト区3の水溶性へミセルロース単独使用の場合も明らかにテスト区4の効果には及ばなかった。また、酢酸モノグリの添加量が高いテスト区5においては苦味を感じたパネラーが多く、美味しさの評価が低い結果となった。
【0037】水溶性へミセルロース100g、酢酸モノグリセリド5gを水895gに溶解し、121℃で10分間、レトルト殺菌して品質改良剤を得た。つぎに、強力粉600g、そば粉400g、食塩10g、水300gを配合しミキサーで15分間混捏し、常法により圧延、切り出し(切刃#22角、麺線厚み1.3mm)を行って得られた麺を沸騰水中で3分間茹で上げ、流水で30秒水洗を行った。水切り後、上記品質改良剤を茹で麺180gあたり3g均一に噴霧し、ポリエチレン製の割り子そばの容器に充填、密封し、本発明品の割り子そばを得た。

【0039】出来上がった鶏肉ピラフの荒熱をとって、容器に充填し、冷凍保存した。使用時に必要量を取り出し、電子レンジで加熱又はフライパンで再度炒めた。こうして出来上がったピラフは、ほぐれやすく、米粒の潰れもないものであった。また、調理後さめてもべたつかず、おいしく食することができた。また、冷凍品をとり出す際もばらけ易い為、必要量取り出し易かった。
【0040】実施例3:うどん
レトルトうどん強力粉100部に対して水20部、食塩4部及び品質改良剤A10部を添加して練り込み、常法によりうどんを製造した。うどんはゆがいた状態でレトルト殺菌(120℃−10分間)し、常温で1週間保存した。このうどんを食する前に熱いつゆを注ぎ、インスタントうどんとした。このうどんはほぐれがよく、熱のかかり方が一様でおいしいものであった。

BACKGROUND OF THE INVENTION
The present invention relates to quality improvement of processed cereal foods, and more specifically, a quality improver that improves the quality of processed foods such as cooked rice, noodles, etc., and the quality improvement by using this improver. Cereal processed food.
[0002]
[Prior art]
With the recent diversification of food, the need for processed foods is increasing. In particular, cereal foods such as cooked rice and noodles have been processed and cooked in large quantities and sold at convenience stores, supermarkets, etc., and have been eaten by many consumers.
[0003] Among these processed foods that are distributed and marketed, particularly problematic are the convenience of processing and the deterioration of quality over time.
Processed cereal foods such as cooked rice and noodles generally contain starch, and during processing / cooking, the starch will flow out onto the surface of the food, causing the foods to bind together. As a result, a problem arises in suitability for processing, such as dumpling or crushing during processing. As a specific example, in the case of cooked rice products, the whole fried rice may not be fried uniformly, or the rice grains may be crushed by a rice ball molding machine. Moreover, if it is a noodle product, it will become difficult to subdivide into one meal by adhesion between noodles. Such problems lead to a decrease in production efficiency and an increase in cost, and also the result is that the finished food is not easy to eat or delicious.
As conventional methods for eliminating the binding property between the foods and improving the looseness, a method of mixing fats or emulsified fats (Patent Document 1), a method of adding a sucrose fatty acid ester having a high HLB ( Patent Document 2), a method of adding an organic acid (Patent Document 3), a method of processing while applying mechanical vibration, and a method of using water-soluble hemicellulose (Patent Document 4).

However, the above-mentioned conventional method can meet various needs such as the efficiency of the hoggle effect, the influence on the flavor, the ability to deal with any type of processed foods, Japanese and Western, and the improvement of gloss in the case of cooked rice. However, with the rapid development and popularization of processed foods, there has been a demand for quality improvers that achieve further efficiency and higher quality, and processed foods with improved quality. There has been a demand for a method for improving the looseness that is more effective than the method.
[0008] Further, recently, an improved rice cooker containing fats and oils, water-soluble hemicellulose and an emulsifier has been proposed. (Patent Document 5) However, this method requires the addition of fats and oils, and is difficult to use for Japanese-style foods anyway for fried rice.

[Problems to be solved by the invention]
An object of the present invention is to provide a quality improving agent for efficiently producing a delicious processed grain food, and a processed grain food using the quality improving agent, by suppressing deterioration in quality such as deterioration of fog during storage. It was.
[0011]
[Means for Solving the Problems]
In light of the above-mentioned problems, the present inventors have conducted extensive research, and as a result, found that a quality improving agent for processed cereal foods using a combination of water-soluble hemicellulose and acetic acid monoglyceride has a remarkable effect, and completes the present invention. It came to.
That is, the present invention is a quality improver for processed grain foods characterized by containing water-soluble hemicellulose and acetic acid monoglyceride, and is obtained by adding the quality improver or surface-treating with the quality improver. Cereal processed food.
In the present invention, the quality improver is added in an amount of 0.01% to 20% as water-soluble hemicellulose and 0.001% to 5% as acetic acid monoglyceride to the processed cereal food. And as a water-soluble hemicellulose used for this invention, the thing derived from a soybean is preferable.
[0014]
DETAILED DESCRIPTION OF THE INVENTION
The processed cereal food of the present invention refers to food obtained by primary processing or further secondary processing of cereal foods (rice, wheat, barley, rice bran, rice bran, etc.). Primary processed foods include cooked rice, barley rice, rice cakes, dried noodles, raw noodles, pasta, etc. Secondary processed foods include foods prepared by re-cooking primary processed foods, such as rice balls, sushi, pilaf, fried rice, and cooked rice , Mixed rice, soba noodles, udon, Chinese noodles, pasta, raw noodles, etc.
These processed cereal foods include processed foods of the final product type intended to be eaten on the spot, including those cooked at home, and semi-finished products that need to be cooked when eaten. This includes foods that are marketed by methods such as refrigeration, freezing, and ice temperature.
Hemicellulose is a polysaccharide extracted from a plant cell wall that is extracted by a dilute alkali, and is often water-soluble and has a property of being easily hydrolyzed by an acid. It is. Hemicellulose is structurally and chemically similar to cellulose, has a lower molecular weight than cellulose, and is a mixture of molecules with different degrees of polymerization of about 150 degrees of polymerization. In this invention, the water-soluble thing is used among this hemicellulose.
The water-soluble hemicellulose of the present invention can be obtained using oil seeds (palm, coconut, corn, cottonseed, etc.), cereals (rice, wheat, etc.) and beans (soybeans, red beans, peas, etc.) as raw materials. From the viewpoint of solubility and industrial properties, those derived from beans, particularly soybeans, especially those derived from cotyledons are preferred.
The method for adding or surface-treating the quality improving agent to cereal foods or processed cereal foods is not particularly limited, but there are the following methods. (1) When making processed cooked rice, it is added to the rice after washing in advance and cooked. In addition, the cooked rice is further processed. (2) Boil noodles or pasta in water or hot water when boiling. (3) Cooked rice, boiled cooked rice, boiled noodles or pasta are entangled with an aqueous solution of this quality improver and surface treated. (4) An aqueous solution of the quality improving agent is sprayed on cooked cooked rice, noodles or boiled rice cakes. (5) Dissolve the quality improver in the seasoning liquid in advance, and apply a surface treatment to the pasta, noodles or rice. (6) The quality improver is mixed with a powder seasoning, and is surface-treated by sprinkling on rice, pasta or noodles. (7) The quality improver is added to the seasoning noodle or pasta dough and kneaded. These methods are selected according to individual food characteristics such as production lines and sales forms.
The acetic acid monoglyceride used in the present invention is a highly lipophilic organic acid monoglyceride also called acetin fat. Usually, the oil and fat and triacetin are transesterified, or the monoglyceride is reacted with acetic anhydride to convert the unreacted product. It is obtained by removing.
There are no particular limitations on the number of carbon atoms in the fatty acid of acetic acid monoglyceride, but those having 8 to 18 carbon atoms are usually used.
With regard to the emulsifier, even if an emulsifier other than the monoglylacetate of the present invention is used, a considerable effect on the fog is obtained. However, from a practical point of view, when other emulsifiers such as lecithin and sugar ester are used in combination with water-soluble polysaccharides without using monoglyceride, these two components interact with each other, making it difficult to treat rice and the like. Among the so-called emulsifiers, monoglyceryl acetate exhibits excellent effects when used in combination with polysaccharides, and has features that are easy to handle practically.
The form of the quality improver is not particularly limited. For example, a liquid state in which water-soluble hemicellulose, acetic acid monoglyceride and other auxiliary agents are dissolved in water, a powdery form obtained by simply mixing these, and a granular form obtained by further increasing the mixture are exemplified. .
The preferred addition amount of the present quality improver is largely unaffected by its shape and the amount of each substance, so it is difficult to define it uniquely. However, it is usually made soluble in cereal foods or processed cereal foods. It suffices for the cellulose to be 0.01% to 20%, and the monoglyceride acetate to be 0.001% to 5% (the same as the weight percent or less), more preferably 0.05 to 5% of the water-soluble hemirose and 0 0.005% to 2%.
The blending ratio of the water-soluble hemicellulose and acetic acid monoglyceride of the quality improver is suitably within the range of 100: 1 to 1: 100, more preferably 50: 1, of water-soluble hemicellulose: acetic acid monoglyceride. To 1:20.
The quality improver must contain water-soluble hemicellulose and monoglyceride acetate, but can be used in combination with other additives as appropriate. Other additives include emulsifiers such as lecithin, glycerin fatty acid ester, sucrose fatty acid ester and sorbitan fatty acid ester, or oily substances such as general animal and vegetable oils and fat-soluble vitamins such as tocopherol, sucrose, maltose, trehalo, Sugars such as sugar, sugar alcohol, dextrin, cloth nori, agar, carrageenan, fur celerin, tamarind seed polysaccharide, tara gum, caraya gum, pectin, xanthan gum, sodium alginate, togant gum, gwar gum, locust bean gum, pullulan, gellan gum, Polysaccharides such as gum arabic, hyaluronic acid, cyclodextrin, chitosan, carboxymethylcellulose (CMC), propylene glycol alginate, modified starch, etc., and hydrolysates of these polysaccharides, zera Down, albumin whey such as sodium caseinate, soluble collagen, albumen, yolk powder, and proteinaceous substances such as soybean protein, salts such as calcium fortified, pH adjusting agents such as sodium acetate and the like.
The quality improver is not only in a powder state but also in an emulsified or suspended state with fats and oils or as a solution such as water or saline, or in a solution added to an organic acid solution such as acetic acid. Can be distributed and sold.
The quality improvement effect of the quality improver on processed cereal foods is that the food is improved in hoggle and no noodle strings or rice grains are bound, so that it is easy to eat and eats when eaten. In addition, it is also a great effect that processing suitability such as easy mixing and less crushing is given in the manufacturing process. For example, taking sushi sold at convenience stores as an example, the following effects can be obtained. If this improved preparation is added and cooked at the time of rice cooking, the rice does not become a lump in the loosening process after cooking, it is easy to mix, and the rice grains are not crushed. When applied to a molding machine, the rice grains are not crushed, so there are few defective products and the product yield is increased. Further, the frequency of cleaning the molding machine is reduced. Conventionally, rice cooking oil has been used to prevent these phenomena, but this is not preferable in terms of flavor. When this quality improver is used, rice cooking oil is not added or the amount added can be reduced.
In addition to the above, the processed and processed cereals to which the present quality improver is added or surface-treated are characterized by the fact that there is no crispiness, that the surface gloss is maintained, and that the quality of noodles and rice is less deteriorated. The effect is maintained even after long-term storage, there is no oil floating when oil is added, it is easy to use for Japanese food, and no special equipment is required because the addition method is simple Can be given.
[0029]
The present invention will be further described with reference to the following examples, but it should be construed that the invention is in no way limited to those examples. In the examples, both parts and% mean weight basis.
In the following examples, water-soluble soybean hemicellulose marketed as “Soya Five Boo S” (manufactured by Fuji Oil Co., Ltd.) was used. As the acetic acid monoglyceride, commercially available “ACETEM 95CO” (manufactured by Danisco) was used.
10 parts of the above water-soluble hemicellulose and 1.0 part of acetic acid monoglyceride are added to 89 parts of water, dissolved at 70 ° C. for 10 minutes, and then retort sterilized at 121 ° C. for 10 minutes to obtain a quality improver A. It was.
A quality improver B was obtained by mixing 190 g of water-soluble hemicellulose and 10 g of monoglyceride acetate.
Example 1 500 g of sushi rice was mixed with 500 g of water (1 time the amount of rice) and a quality improver as shown in Table 1. A rice cooker for household use (manufactured by Sanyo Electric Co., Ltd., microcomputer) Rice was cooked using a rice cooker ECJ-EA18). Sushi vinegar (26% of rice) was added to the rice thus cooked and cooled to 30 ° C. while mixing with rice scoop. Shari balls are made with a commercial shari ball molding machine ("Sushi Maker ASM390" manufactured by Autotechnica), and the state of the rice grains (presence of dumplings, presence or absence of crushed rice grains, luster), taste (texture) , Overall taste, etc.) were evaluated by 10 panelists based on a five-step evaluation. The results are shown in Table 2.
[Table 1]
Figure 2004222550
[Table 2]
Figure 2004222550
From the results shown in Table 2, the evaluation of Test Group 4 in which appropriate amounts of water-soluble hemicellulose and monoglyceride acetate were added was good. No effect was observed in test group 2 in which acetic acid monoglyceride was used alone, and in the case of using water-soluble hemicellulose alone in test group 3, the effect of test group 4 was clearly not reached. In addition, in the test section 5 where the amount of monoglyceryl acetate added was high, there were many panelists who felt bitterness, and the evaluation of taste was low.
A quality improver was obtained by dissolving 100 g of water-soluble hemicellulose and 5 g of acetic acid monoglyceride in 895 g of water and sterilizing by retort at 121 ° C. for 10 minutes. Next, 600 g of strong powder, 400 g of buckwheat flour, 10 g of salt, and 300 g of water are mixed and kneaded for 15 minutes with a mixer, and rolled and cut (cutting blade # 22 square, noodle string thickness 1.3 mm) by a conventional method. The noodles were boiled in boiling water for 3 minutes and washed with running water for 30 seconds. After draining, 3 g of the above quality improver was uniformly sprayed per 180 g of boiled noodles, filled in a container of polyethylene groats and sealed, and the groats of the present invention were obtained.
Example 2: 250 g of pilaf chicken cut into 2 cm squares, onion heated in a microwave oven cut into 1 cm squares, quick peppers cut into 1 cm squares, cut into the same size . Fried chicken over high heat and sprinkled with a little white wine. Add butter, stir-fried onion and bell pepper, and then add cooked rice that has been surface-treated by mixing 100 g of demiglace sauce, 80 g of bouillon, and 25 g of quality improver A in advance. Stir until it is gone.
The finished chicken pilaf was subjected to rough heat, filled into a container, and stored frozen. At the time of use, the necessary amount was taken out and heated in a microwave or fried again in a frying pan. The resulting pilaf was easy to loosen and did not crush rice grains. In addition, it was not sticky even after cooking, and it was delicious. Moreover, since it was easy to separate when taking out the frozen product, it was easy to take out the necessary amount.
Example 3 Udon retort Udon noodles were prepared by adding 20 parts of water, 4 parts of salt and 10 parts of a quality improver A to 100 parts of strong powder of udon and kneaded. The udon was distorted by retort sterilization (120 ° C. for 10 minutes) and stored at room temperature for 1 week. Before eating this udon, we poured hot soy sauce to make instant udon. This udon was loose and had a uniform and delicious heat.
Example 4 (Instant Yakisoba)
The quality improver B was added and dissolved in a commercial dry noodle type instant yakisoba-attached liquid sauce in an amount of 0.4% of the dry noodle weight. The instant yakisoba was prepared and eaten according to a conventional method, but there was no stickiness of the noodles, the noodles were well loosened, the sauce was uniformly dispersed, and the taste was excellent. In addition, it was not sticky over time and it was delicious.
Example 5: A fried rice stirrer (Rotary Chef RC-1T = manufactured by Kumano Kobo Co., Ltd.) was heated to 220 ° C., then 20 g of stir-fried oil was added, and 50 g of chopped onion was lightly fried. 150 g of eggs were added and fried lightly, and then 1200 g of cooked rice and 100 g of grilled pork were added and fried for 2 minutes, except that 24 g of quality improver A was added. The rice was very easy to disperse, so there was almost no crushed rice grains during the frying work and it was very easy to fry. When the quality improving agent A cooked at the same time was added without addition, it took 5 minutes after adding the rice to obtain the equivalent fried feeling. In this case, the rice grains were considerably crushed.
