Definitions
- the present invention relates to a fat composition suitable as a food modifier.
- Instant noodles are usually a process of mixing and kneading raw materials (mixing and kneading process), a process of rolling the kneaded dough to obtain a noodle band (rolling process), a process of cutting out the noodle band and obtaining a noodle string (cutting process) ), A process of steaming the noodle strings (steaming process), a process of molding the steamed noodles into a shape suitable for packaging (molding process), and a process of drying the molded noodles (drying process).
- the steaming step starch on the surface of the noodle strings is gelatinized ( ⁇ -ized) and the outer layer of the noodle strands is strengthened, so that cracks of the noodle strings in the subsequent drying step can be prevented. Moreover, since starch swells by the said steaming process, the hot water return time of instant noodles which are final products can be shortened. Therefore, the steaming process is an essential process in the production of instant noodles.
- the phenomenon that noodle strings are bound to each other also occurs due to gelatinization of the surface of the noodle strings by the steaming step. If noodle strings are bound together, molding defects are likely to occur in the subsequent molding process. Moreover, the instant noodles obtained have a binding portion that is difficult to return to hot water, and the texture becomes uneven. Thus, the steaming process greatly affects the quality of instant noodles.

Abstract
Description
上記蒸し工程により、麺線表面の澱粉が糊化(α化)し、麺線外層が強化されるため、その後の乾燥工程における麺線のひび割れ等を防止することができる。また、上記蒸し工程により澱粉が膨潤するため、最終製品である即席麺の湯戻り時間を短縮することができる。したがって、上記蒸し工程は即席麺の製造において必須の工程とされている。
一方、上記蒸し工程による麺線表面の糊化により、麺線同士が結着する現象も生じる。麺線同士が結着するとその後の成形工程において成形不良が生じやすくなる。また、得られる即席麺は結着部分が湯戻りしにくく、食感が不均一となる。
このように、上記蒸し工程は即席麺の品質に大きく影響する。
例えば特許文献1には、エステル化率が20%以下で、かつ、HLBが8~12のポリグリセリン脂肪酸エステルと大豆レシチンを含有する茹で・蒸し麺類用油脂組成物が記載され、この油脂組成物を茹でた中華麺やうどんに噴霧等することにより、麺線のほぐれ性を向上させたことが記載されている。
[ジグリセリンモノオレートの含有量]×2≧[ジグリセリンモノラウレートの含有量]
また本発明は、上記油脂組成物又は乳化組成物を用いた食品を提供するものである。
また本発明は、上記油脂組成物又は乳化組成物と、蒸し工程後の麺線とを接触させることにより、前記麺線表面に前記食用油脂を付着させることを含む、即席麺の製造方法を提供するものである。
さらに本発明は、上記油脂組成物又は乳化組成物の存在下で炊飯することを含む、米飯の製造方法を提供するものである。
本発明において、成分含有量は、特に断りのない限り質量基準である。
また、いわゆる炊き込みご飯等を作る際には、炊飯時の水に醤油やダシが加えられる。したがって、調味液中に容易に乳化分散でき、且つこの乳化分散状態が高温下においても安定な油脂組成物は、米飯のほぐれ性改善用途において汎用性が高く、実用性に優れたものとなる。
また本発明は、上記油脂組成物の油脂を油相として有する水中油型乳化組成物の提供に関する。
また本発明は、上記油脂組成物又は乳化組成物を用いた食品の提供に関する。
さらに本発明は、上記油脂組成物又は乳化組成物を用いた即席麺ないし米飯の製造方法の提供に関する。
本発明はこれらの知見に基づきさらに検討を重ね、完成されるに至ったものである。
本発明に用いる食用油脂は、植物性油脂であることが好ましい。当該植物性油脂としては、例えば、大豆油、菜種油、コーン油、綿実油、サフラワー油、オリーブ油、パーム油、米油、ひまわり油、胡麻油、及びこれらのエステル交換油もしくは分別油から選ばれる1種又は2種以上の油脂が挙げられ、大豆油、菜種油、及びコーン油から選ばれる油脂が好ましい。
[DGMOの含有量]×2≧[DGMLの含有量] (I)
本発明の油脂組成物中、DGMLの含有量とDGMOの含有量とが上記数式(I)を満たすことにより、DGMOが、DGMLを油脂中に溶解するための可溶化剤として効果的に機能することができ、食用油脂中へのDGMLの溶解安定性をより高めることができる。乳化組成物の耐塩・耐熱性を高める観点から、DGMLの含有量(質量%)とDGMOの含有量(質量%)は下記数式(II)を満たすことが好ましい。
[DGMOの含有量]≧[DGMLの含有量]×2 (II)
本発明の油脂組成物がレシチンを含有する場合、本発明の油脂組成物中のレシチンの含有量は0.5~3.0質量%が好ましく、1.0~2.0質量%がより好ましい。
例えば、即席麺の製造において、蒸し工程後の麺線表面に付着させることにより、麺線同士の結着を抑制し、ほぐれ性に優れた即席麺を得ることができる。また、本発明の油脂組成物を調味液中に乳化分散させて乳化液を調製し、当該乳化液を麺線表面に噴霧することにより、麺線のほぐれ性を効果的に改善しながら麺線に所望の味付けをすることができる。しかも、本発明の油脂組成物を用いれば、上記の麺線表面への乳化液の噴霧を、高温下においても安定して実施できる。すなわち本発明の油脂組成物は即席麺等の工業的生産に好ましく適用できる。
本発明の乳化組成物は、本発明の油脂組成物の油脂を油相(分散相)として有する。本発明の乳化組成物を構成する水相(連続相)は、水又は水性液である。当該水相は塩分(食塩)等を含有する調味液であってもよい。本発明の乳化組成物は、水相が塩分を含む場合であっても優れた乳化安定性を示す。そのため、本発明の乳化組成物を食品に付着させることにより、水相が有する塩分等の調味成分により食品に所望の味付けをすることができ、且つ、油相の作用によって食品のほぐれ性、食感、風味、外観等を改質することができる。
本発明の食品は、各種食品の通常の製造工程において、本発明の油脂組成物ないし乳化組成物を配合することで得ることができる。なかでも、本発明の食品は、当該食品の製造工程において、食品表面に本発明の油脂組成物ないし乳化組成物を付着させ、当該付着液を食品に浸透させ、あるいは食品表面になじませた形態が好ましい。本発明の食品が即席麺あるいは米飯である場合を例にとって、その生産方法の一例を説明する。
蒸し工程後の麺線と本発明の油脂組成物又は乳化組成物とを接触させる際には、当該麺線100質量部に対し、食用油脂が0.01~0.8質量部付着するように接触させることが好ましく、0.05~0.5質量部付着するように接触させることがさらに好ましい。

上記調製例1で調製した各油脂組成物を室温まで冷却し、油脂組成物の風味について5名の専門パネルの各々が、後述の評価基準に従って風味を評価した。風味の評価基準を以下に示す。5名の専門パネルの評価結果はすべて同じとなった。
(風味の評価基準)
A:乳化剤の異味を感じない。
B:乳化剤の異味を感じる。
上記調製例1で調製した各油脂組成物を室温まで冷却し、各油脂組成物につき、50mLずつ、5本の瓶(底面φ4.0cm、高さ7.5cm)に分注して密封した。20℃で1週間静置した後、外観を目視観察し、下記評価基準により評価した。結果を下表に示す。
(乳化剤の溶解安定性評価基準)
A:5つの瓶すべてにおいて沈殿が生じなかった。
B:1つ以上の瓶で沈殿が生じた。
上記調製例1で調製した各油脂組成物1gに対し、純水49.0gを混合して5分間、緩やかに撹拌し、水中油型に乳化分散させた。次いで80℃のウォーターバス中で1時間、緩やかに撹拌を続けた。その後、室温に戻して20分間静置し、乳化状態を目視観察し、下記評価基準により評価した。結果を下表に示す。なお、各油脂組成物について、同じ試験を5回実施したが、いずれも同じ評価結果となった。この試験では評価4を合格とした。
(評価基準)
4:全体が均質に白濁しており、均一な乳化分散状態である。
3:表面にクリーミング層が生じている。クリーミング層以外の部分は均質に白濁しており、光が透過しない状態である。
2:表面にクリーミング層が生じている。クリーミング層以外の部分は均質に白濁しているが、白濁の度合がやや薄く、光が透過する状態である。

上記調製例1で調製した各油脂組成物1gに対し、10質量%食塩水49.0gを混合して5分間、緩やかに撹拌し、水中油型に乳化分散させた。次いで60℃のウォーターバス中で1時間、緩やかに撹拌を続けた。その後、室温に戻して20分間静置し、乳化状態を目視観察し、上記試験例3と同じ評価基準により評価した。結果を下表に示す。なお、各油脂組成物について、同じ試験を5回実施したが、いずれも同じ評価結果となった。この試験では評価2以上を合格とした。
また、油脂組成物が乳化剤としてDGMLのみを含有する場合には、油脂組成物の保存中に沈殿が生じ、実用性に劣るものであった(比較例7及び8)。ここで、油脂組成物がDGMOを含有しない場合であっても、DGMLの含有量を所定のレベルまで減らすことにより、油脂組成物の保存安定性は高まるが、この場合には、水中油型乳化組成物を形成した際の乳化安定性に劣る結果となった(比較例6)。
また、油脂組成物がDGMOとDGMLの両乳化剤を含有する場合でも、DGMOの含有量が本発明で規定するよりも少ないと、塩分を含む水性液中に乳化分散させた際に、高温下において乳化形態を安定的に維持することができず(比較例9、10、16~18)、逆にDGMOの含有量が本発明で規定するよりも多い場合にも、水中に乳化分散させた際に、高温下において乳化形態を安定的に維持することができなかった(比較例14)。
また、油脂組成物中のDGMOの含有量とDGMLの含有量が、本発明で規定する関係を満たさない場合には、油脂組成物の保存中に沈殿が生じ、実用性に劣る結果となった(比較例11及び12)。
また、油脂組成物がDGMOとDGMLの両乳化剤を含有する場合でも、DGMLの含有量が本発明で規定するよりも少なかったり多かったりすると、水中に乳化分散させた際に、高温下において乳化形態を安定的に維持することができなかった(比較例13、15)。
また、DGMLの含有量を本発明で規定する範囲内とした上で、DGMOに代えて他の乳化剤を配合した油脂組成物は、油脂組成物の保存中に沈殿が生じて実用性に劣る結果となったり(比較例20~24)、乳化安定性に劣る結果となったりした(比較例19)。
また、DGMOの含有量を本発明で規定する範囲内とした上で、DGMLに代えて他の乳化剤を配合した油脂組成物は、油脂組成物の保存中に沈殿が生じ、実用性に劣る結果となった(比較例25~42)。
生米(新潟産コシヒカリ、平成26年産)600gを洗米後、20℃の水に1.5時間浸漬し、ざるに上げて水切りした。この浸漬米700gに水700gを加え、更に、ナタネ油6g、又は、実施例2、実施例10、実施例22、比較例4もしくは比較例10の油脂組成物6gを加えて軽くかき混ぜた後、電気炊飯器により炊飯した。
炊き上がった米飯をバットに広げてしゃもじで約1分間ほぐし、室温で30分間静置することで粗熱をとって試験用米飯とした。
上記調製例2において、ナタネ油6g又は油脂組成物6gに代えて、ナタネ油6g又は油脂組成物6gにβカロテン(DSMニュートリションジャパン社製)を0.1質量%濃度となるように混合したものを使用し、βカロテンの色の広がり度合に基づき、ナタネ油及び油脂組成物の米飯に対する分散性を、下記評価基準により評価した。
(米飯に対する分散性評価基準)
A:米飯全体が均質に着色している(米飯全体に油脂がなじんでいる)。
B:米飯がほぼ均一に着色している。
C:着色が偏っている(米飯のところどころに油脂が偏在している)。
上記調製例2で得られた試験用米飯について、ほぐれ性を下記評価基準により評価した。結果を下表に示す。
(ほぐれ性の評価基準)
A:全体的に米粒同士の結着が抑えられてほぐし易い。
B:全体的にほぐし易いがやや塊がある。
C:全体として米粒同士の結着が強くほぐし難い。
上記調製例2で得られた試験用米飯を15℃で2時間保存したもの、及び15℃で24時間保存したものを食し、下記評価基準により味を評価した。結果を下表に示す。
(味の評価基準)
A:油脂由来の油っぽさを感じない。
B:油っぽさを感じる。
上記調製例2で得られた試験用米飯を15℃で2時間保存したもの、及び15℃で24時間保存したものについて、外観を目視観察し、下記評価基準により評価した。結果を下表に示す。
(外観の評価基準)
A:米飯全体にツヤがある。
B:米飯全体にツヤがない。
生めん(商品名:細麺、麺心屋社製)を沸騰水中で1分間茹でた後、湯切りし、イオン交換水で麺の表面のぬめりを除去した。得られた麺の20gを、実施例2、実施例8、実施例10、実施例14、実施例22、比較例4又は比較例10の油脂組成物の含有量が2.0質量%になるように水で希釈して得た、水中油型の乳化液である希釈液(ほぐし液)30mL中に、30秒間浸漬した。次いで麺を取り出し、麺に付着した過剰の希釈液をエアーブローで除去し、カップに入れた。同様にして、希釈液に浸漬後、過剰の希釈液を除去した麺の入ったカップを9個用意した(合計10カップ)。各カップに入った麺について、当該カップに入れてから10分間静置後に、麺線10本を1本ずつ引き上げた。引き上げた合計100本(10本×10カップ)の麺線について、各々の麺線のほぐれ性を下記評価基準により評価した。この評価結果に基づき下記式からほぐれ率を算出した。結果を表7に示す。
A:麺線が切断されずに一本ずつ引き上げられる
B:麺線を引き上げた際に、麺線が切断されてしまう、又は、麺線に結着してからまった麺塊が浮上する
水35質量部に食塩1.5質量部、粉末かん水(オリエンタル酵母工業社製)0.4質量部を溶解し、かんすい水を調製した。このかん水を小麦粉100質量部に加え、15分間混合してそぼろ状の麺生地とした。
製麺ロールを用い、ロール間隙4.5mm、3.0mm、2.0mmの順に圧延し、次いで麺帯をさらに製麺ロールで圧延し、約1.25mm厚の麺帯とした。その後、切刃♯18角を用いて麺線(幅1.25mm)に切り出し、さらにこの麺線を長さ約30cmに切り、生中華麺を得た。得られた生中華麺を、蒸し器を用いて3分間蒸し、蒸し中華麺を得た。蒸し中華めん80gを、上述したほぐし液のうち、実施例22の乳化組成物を用いたほぐし液100mLに浸漬し、金網上で直径10cmの円柱状に成型した。次いで余分なほぐし液をエアブローにて除去した後、熱風乾燥器を用いて水分が10%程度になるように乾燥し、即席中華麺を調製した。
調製した即席中華麺を沸騰水で4分間湯戻しした。湯戻した麺は、箸を用いて麺を2~3回ほぐすだけで、麺全体が素早く簡単にほぐれた。
