【発明の属する技術分野】
本発明は、特殊な設備を使用せずに表皮に殆ど亀裂が入らない球状のシューケースが得られるシュー用乳化油脂組成物及びこれを用いたシューケースに関するものである。
【0002】
【従来の技術及び発明が解決しようとする課題】
一般に広く市販されているシューケースは皮質が厚く、表面に亀裂の多く入った所謂キャベツ型のものが多く、これがシューケースの特徴であると広く認識されている。一方、一般的なシューケースとは全く逆に皮質が薄く、表面に亀裂が殆ど入らない球状の特殊な形状のシューケースも一部で市販されており、好評を博している。
【0003】
このような薄皮で表皮に亀裂の少ないシューケースを得る手段として、シュー生地焼成時に多量の水蒸気を生地に散布した後、生地上に蓋を被せる方法及びその設備(特開平4−53442号公報)、前記設備を採用し、更に焼成直後20秒以内にフィリングを充填することにより皮質をソフトで滑らかに仕上げる方法(特開平4−53440号公報)が提案されている。
【0004】
しかしながら、上記の特開平4−53442号公報及び特開平4−53440号公報の方法では、設備投資が必要となり、しかもその設備は他の用途には転用困難であるため、商品が高コストとなりやすいという問題点があった。
【0005】
従って、本発明の目的は、特殊な製造設備の導入を必要とせずに、薄皮、球状のシューケースを得ることを可能とするシュー用乳化油脂組成物及びこれを用いたシューケ−スを提供することにある。
【0006】
【課題を解決するための手段】
本発明者等は、鋭意研究した結果、油相部及び水相部にそれぞれ特定の化合物を含有する乳化油脂組成物が、上記目的を達成し得ることを知見した。
【0007】
本発明は、上記知見に基づきなされたもので、油相部及び水相部からなるシュー用乳化油脂組成物において、上記油相部がステアロイル乳酸カルシウムを含有し、上記水相部がカゼインナトリウムを含有することを特徴とするシュー用乳化油脂組成物を提供するものである。
【0008】
また、本発明は、上記シュ−用乳化油脂組成物を用いたことを特徴とするシュ−ケ−スを提供するものである。
【0009】
【発明の実施の形態】
以下、先ず、本発明のシュー用乳化油脂組成物について詳述する。

【0010】
上記CSLの含有量は、全組成物中好ましくは0.4〜1.8重量%(以下、単に「%」とする)、より好ましくは0.6〜1.0%、さらに好ましくは0.7〜0.9%である。該含有量が0.4%未満では、皮を薄く、なおかつ亀裂を少なく仕上げる上で必須条件となるシュー生地の滑らかな物性、十分な膨化が期待できず、本発明の目的とするシューケースが得られない場合がある。一方、1.8%を越えると、一般的な配合範囲内で本油脂組成物を用いた場合に法規で規定されたCSLの含有量の上限(0.4%対シュー皮製品) を超過する恐れがあるので、好ましくない。
【0011】
また、上記カゼインナトリウムの含有量は、全組成物中好ましくは1.0〜4.5%、より好ましくは1.5〜4.0%、さらに好ましくは2.0〜3.0%である。該含有量が1.0%未満では、シュー生地の乳化状態が悪化するのみならず、シュー生地製造時に要求される吸卵性に劣り製品ボリュームも劣る恐れがある。一方、4.5%を越えると、生地の硬化を招き焼成中にシュー生地の膨化が起こる際に表面に亀裂が生じすぎたり、また、食感が悪くなる恐れがあるので、好ましくない。
【0012】
また、本発明のシュー用油脂乳化組成物における上記油相部には、食用油脂が使用され、該食用油脂としては、一般に食用に供される油脂が使用でき、例えば、マーガリンに用いられるナタネ油、コーン油、大豆油、米油及びパーム油等の植物油脂、又は牛脂、豚脂及び魚油等の動物性油脂、或いはそれらを水素添加又はエステル交換して得られる加工油脂等が挙げられる。これらの食用油脂は、単独で又は併用して使用することができる。
また、上記食用油脂の融点は、25〜45℃であることが望ましい。
【0013】
上記食用油脂の使用量は、全組成物中、油中水型の乳化状態とする場合には、好ましくは45〜95%、更に好ましくは50〜85%であり、また、水中油型の乳化状態とする場合には、好ましくは45〜80%、更に好ましくは50〜70%である。
【0014】
また、本発明のシュー用油脂乳化組成物には、乳化剤を使用することができ、該乳化剤は、上記油相部及び上記水相部の何れか一方又は両方に加えることができる。
上記乳化剤としては、食品添加物として使用可能なものであれば、どのようなものでもよく、例えば、グリセリン脂肪酸エステル、ショ糖脂肪酸エステル、レシチン、プロピレングリコール脂肪酸エステル、ソルビタン脂肪酸エステル、ポリグリセリン脂肪酸エステル、ポリグリセリン縮合リシノレイン酸エステル、有機酸モノグリセリド等が挙げられる。これらの乳化剤は、1種又は2種以上で使用することができる。
【0015】
上記乳化剤の使用量は、全組成物中、好ましくは0.02〜2.5%,更に好ましくは0.5〜2.0%である。
【0016】
また、上記油相部には、酸化防止剤その他の親油性成分を使用することができる。
【0017】
本発明のシュー用油脂乳化組成物における上記水相部に使用される水の使用量は、全組成物中、好ましくは5〜55%、更に好ましくは15〜50重量%である。
【0018】
また、上記水相部には、リン酸塩やアルカリ塩を使用することができ、該リン酸塩及び上記アルカリ塩は、上記カゼインナトリウムの溶解性向上を目的として添加される。
【0019】
また、上記油相部又は上記水相部には、一般マーガリンと同様に、食塩、粉乳、香料及び着色料を添加することも可能である。これらの添加量は任意であるが、一般的には全組成物中0.05〜4.0%、好ましくは0.3〜2.0%が適当である。
【0020】
本発明のシュー用乳化油脂組成物は、例えば、以下のようにして製造することができる。即ち、加熱溶解した食用油脂に、CSLやその他の親油成分を加えて油相部を作成する。一方、水にカゼインナトリウムやその他の親水成分を加えて水相部を作成する。また、乳化剤を、その溶解性に応じて、上記油相部又は上記水相部の何れか一方又は両方に添加する。油中水型乳化油脂組成物を形成する場合には、油相部を攪拌しながら、水相部を添加して乳化する。一方、水中油型乳化油脂組成物を形成する場合には、水相部を攪拌しながら、油相部を添加して乳化する。そして、急冷混和して、可塑性を有する本発明のシュー用乳化油脂組成物を得る。
【0021】
本発明のシュー用乳化油脂組成物は、表面からの水分の飛散、カビ等の発生の点から油中水型乳化油脂組成物とするのが好ましい。
【0022】
次に、本発明のシューケースについて詳述する。
本発明のシューケースは、上述した本発明のシュー用乳化油脂組成物を用いたことを特徴とする。
【0023】
本発明のシューケースは、その配合に特に限定されるものではないが、小麦粉100重量部に対し、上記シュー用乳化油脂組成物を50〜150重量部、好ましくは70〜100重量部、水を200〜300重量部、好ましくは220〜270重量部、全卵を100〜300重量部、好ましくは150〜240重量部から構成される配合が望ましい。
ここで、本発明のシューケースの配合において、上記シュー用乳化油脂組成物が50重量部未満であると、シューケースの膨らみが不十分となり好ましくなく、150重量部を越えると、食感、風味が悪くなる傾向があるため好ましくない。
【0024】
また、本発明のシューケースには、上記の成分に加えて、重炭酸アンモニウム、重炭酸ナトリウム等の膨張剤を加えることができ、更に、その他、常用の着色料、香料、防腐剤等も適宣使用できる。
【0025】
本発明のシューケースは、例えば、以下のようにして製造することができる。
即ち、本発明のシュー用乳化油脂組成物を、水とともに加熱煮沸し、この中に小麦粉を添加して捏和し、一般シュー皮同様にシュー皮を形成するに適した糊化状態にした後、卵をミキシングしながら数回に分けて加え、シュー生地を十分に乳化し、必要な場合は前述の膨張剤、着色料、香料、防腐剤等を添加した後、さらに液卵を加えて硬さを調整してシュー生地を得る。得られたシュー生地を絞り、オーブン等により焼成して本発明のシューケースを得る。

BACKGROUND OF THE INVENTION
The present invention relates to an emulsified oil / fat composition for a shoe, which can obtain a spherical shoe case with almost no cracks in the skin without using special equipment, and a shoe case using the same.
[0002]
[Prior art and problems to be solved by the invention]
In general, shoe cases that are widely available on the market have a large cortex and many so-called cabbage types having many cracks on the surface, and this is widely recognized as a characteristic of shoe cases. On the other hand, in contrast to a general shoe case, a special case with a spherical shape with a thin cortex and almost no cracks on the surface is also commercially available, and has been well received.
[0003]
As a means of obtaining a shoe case with such a thin skin and less cracks in the epidermis, a method and equipment for applying a lid on the fabric after spraying a large amount of water vapor onto the fabric during baking of the shoe fabric (JP-A-4-53442) A method (JP-A-4-53440) has been proposed in which the above-mentioned equipment is employed and the cortex is softly and smoothly finished by filling the filling within 20 seconds immediately after firing.
[0004]
However, the methods disclosed in Japanese Patent Laid-Open No. 4-53442 and Japanese Patent Laid-Open No. 4-53440 require capital investment, and the equipment is difficult to be diverted to other uses, so that the product tends to be expensive. There was a problem.
[0005]
Accordingly, an object of the present invention is to provide an emulsified oil / fat composition for a shoe that makes it possible to obtain a thin skin and a spherical shoe case without requiring the introduction of special production equipment, and a shoe case using the same. There is.
[0006]
[Means for Solving the Problems]
As a result of intensive studies, the present inventors have found that an emulsified oil / fat composition containing a specific compound in each of the oil phase part and the water phase part can achieve the above object.
[0007]
The present invention has been made based on the above knowledge, and in the emulsified oil composition for shoes comprising an oil phase part and an aqueous phase part, the oil phase part contains stearoyl calcium lactate, and the aqueous phase part contains sodium caseinate. The emulsified oil composition for shoes is characterized by containing.
[0008]
The present invention also provides a shoe case using the above-mentioned emulsified oil composition for shoe.
[0009]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, first, the emulsified oil / fat composition for shoes of the present invention will be described in detail.
The emulsified fat and oil composition for shoes of the present invention comprises an oil phase part and an aqueous phase part, the oil phase part contains stearoyl calcium lactate (hereinafter referred to as “CSL”), and the aqueous phase part contains sodium caseinate. It is characterized by doing.
[0010]
The content of the CSL is preferably 0.4 to 1.8% by weight (hereinafter simply referred to as “%”) in the total composition, more preferably 0.6 to 1.0%, and still more preferably 0.8%. 7-0.9%. If the content is less than 0.4%, smooth physical properties and sufficient swelling of the shoe fabric, which are essential conditions for finishing the skin thinly and with few cracks, cannot be expected. It may not be obtained. On the other hand, if it exceeds 1.8%, it will exceed the upper limit of CSL content (0.4% vs. shoe skin product) stipulated by laws and regulations when this oil composition is used within the general blending range. Because there is a fear, it is not preferable.
[0011]
The content of sodium caseinate is preferably 1.0 to 4.5%, more preferably 1.5 to 4.0%, and still more preferably 2.0 to 3.0% in the entire composition. . If the content is less than 1.0%, not only the emulsified state of the shoe dough is deteriorated, but also the egg-absorbing property required when producing the shoe dough is inferior and the product volume may be inferior. On the other hand, if it exceeds 4.5%, the dough is hardened, and when the shoe dough expands during baking, the surface may be excessively cracked or the texture may be deteriorated.
[0012]
In addition, edible fats and oils are used for the oil phase part in the emulsified oil composition for shoes according to the present invention. As the edible fats and oils, fats and oils generally used for food can be used. For example, rapeseed oil used for margarine , Vegetable oils such as corn oil, soybean oil, rice oil and palm oil, or animal fats such as beef tallow, pork tallow and fish oil, or processed oil obtained by hydrogenating or transesterifying them. These edible fats and oils can be used alone or in combination.
Moreover, as for the melting | fusing point of the said edible oil and fat, it is desirable that it is 25-45 degreeC.
[0013]
The amount of the edible oil / fat is preferably 45 to 95%, more preferably 50 to 85% when the water-in-oil type emulsified state is used in the entire composition, and the oil-in-water type emulsified type. When making it into a state, Preferably it is 45 to 80%, More preferably, it is 50 to 70%.
[0014]
Moreover, an emulsifier can be used for the oil-fat emulsion composition for shoes of this invention, and this emulsifier can be added to any one or both of the said oil phase part and the said water phase part.
The emulsifier may be any as long as it can be used as a food additive. For example, glycerin fatty acid ester, sucrose fatty acid ester, lecithin, propylene glycol fatty acid ester, sorbitan fatty acid ester, polyglycerin fatty acid ester , Polyglycerol condensed ricinoleic acid ester, organic acid monoglyceride and the like. These emulsifiers can be used alone or in combination of two or more.
[0015]
The amount of the emulsifier used is preferably 0.02 to 2.5%, more preferably 0.5 to 2.0% in the entire composition.
[0016]
Moreover, antioxidant and other lipophilic components can be used in the oil phase part.
[0017]
The usage-amount of the water used for the said water phase part in the oil-fat emulsion composition for shoes of this invention becomes like this in a whole composition, Preferably it is 5-55%, More preferably, it is 15-50 weight%.
[0018]
Moreover, a phosphate and an alkali salt can be used for the said water phase part, and this phosphate and the said alkali salt are added for the purpose of the solubility improvement of the said casein sodium.
[0019]
Moreover, salt, powdered milk, a fragrance | flavor, and a coloring agent can also be added to the said oil phase part or the said water phase part similarly to general margarine. These addition amounts are arbitrary, but generally 0.05 to 4.0%, preferably 0.3 to 2.0% is appropriate in the total composition.
[0020]
The emulsified oil composition for shoes of the present invention can be produced, for example, as follows. That is, an oil phase portion is prepared by adding CSL and other lipophilic components to edible fats and oils dissolved by heating. On the other hand, sodium caseinate and other hydrophilic components are added to water to create an aqueous phase. Moreover, an emulsifier is added to either one or both of the oil phase part and the water phase part depending on its solubility. When forming a water-in-oil type emulsified oil / fat composition, the water phase part is added and emulsified while stirring the oil phase part. On the other hand, when forming an oil-in-water emulsified oil and fat composition, the oil phase part is added and emulsified while stirring the water phase part. And it cools and mixes and the emulsified oil-fat composition for shoes of this invention which has plasticity is obtained.
[0021]
The emulsified oil / fat composition for shoes of the present invention is preferably a water-in-oil emulsified oil / fat composition from the viewpoint of scattering of moisture from the surface, generation of mold and the like.
[0022]
Next, the shoe case of the present invention will be described in detail.
The shoe case of the present invention is characterized by using the above-described emulsified oil composition for shoes of the present invention.
[0023]
The shoe case of the present invention is not particularly limited to the blending thereof, but 50 to 150 parts by weight, preferably 70 to 100 parts by weight of the emulsified oil / fat composition for shoes is added to 100 parts by weight of flour. It is desirable to have a composition comprising 200 to 300 parts by weight, preferably 220 to 270 parts by weight, and 100 to 300 parts by weight, preferably 150 to 240 parts by weight of whole eggs.
Here, in the composition of the shoe case of the present invention, if the emulsified oil / fat composition for shoes is less than 50 parts by weight, the swelling of the shoe case becomes unsatisfactory, and if it exceeds 150 parts by weight, the texture and flavor are increased. Is not preferable because it tends to deteriorate.
[0024]
Further, in addition to the above components, a swelling agent such as ammonium bicarbonate and sodium bicarbonate can be added to the shoe case of the present invention, and other colorants, fragrances, preservatives and the like are also suitable. Can be used.
[0025]
