Description

技術分野
本発明は、起泡性チョコレート類及び起泡性チョコレート類の製造法に関する。詳しくは、冷蔵、冷凍用途に利用できる気泡安定性に優れた起泡性チョコレート類であって、チョコレート類中の高融点油脂成分とチョコレート類中の高融点油脂成分を除いた成分の融点との温度差が30℃以上である起泡性チョコレート類に関する。
背景技術
近年、チョコレート製品の多様化が進み、その中でも気泡入りチョコレートが一つのカテゴリーを築きつつある。チョコレート類を含気させる方法としては、チョコレート生地に乳化剤を添加し起泡する方法(特開平1−144934号公報)、構成脂肪酸残基の炭素数の合計が58以上のトリグリセリドを一定以上含む油脂をチョコレート生地中に配合し、その油脂結晶により気泡を安定化させ、チョコレート生地の比重を下げる方法(特開平3−201946号公報)、予め気泡を含ませたあと予備冷却したチョコレート等を、減圧用容器の中に投入し、減圧してチョコレートを膨化し、全体を硬化する方法(特開平6−62742号公報)等が知られている。
しかしながら、これらのものはカカオマス、カカオ脂を主成分とするチョコレート生地に気泡を含ませるものであり、その用途に限界があった。
発明の開示
本発明は、冷蔵、冷凍用途に利用できる気泡安定性に優れた起泡性チョコレート類及びその製造法を提供することを目的とする。
本発明者らは上記課題を解決するために、鋭意研究を重ねた結果、本発明を完成するに至った。
即ち、チョコレート類中の高融点油脂成分とチョコレート類中の高融点油脂成分を除いた成分の融点との温度差が30℃以上である起泡性チョコレート類及びチョコレート類中の高融点油脂成分とチョコレート類中の高融点油脂成分を除いた成分の融点との温度差が30℃以上である起泡性チョコレート類生地を溶融状態から急冷固化することを特徴とする起泡性チョコレート類の製造法である。
発明を実施するための最良の形態
本発明におけるチョコレート類とは、油脂類と糖類を必須成分とし、必要によりカカオマスやココアパウダー、粉乳等の各種粉末食品、乳化剤、香料、色素等の中から選択した原料を任意の割合で混合し、常法によりロール掛け及びコンチング処理して得たものを意味する。油脂類としては具体的には、大豆油、綿実油、コーン油、サフラワー油、オリーブ油、パーム油、菜種油、米ぬか油、ゴマ油、カポック油、ヤシ油、パーム核油、ババス油、カカオ脂、乳脂、ラード、魚油、鯨油等の各種の動植物油脂及びそれらの硬化油、分別油、エステル交換油等が例示できる。
糖類としては、単糖類、オリゴ糖類、糖アルコール類、デキストリン、水飴等が例示できる。単糖類としては具体的には、グルコース、フルクトース、マンノース、キシロースを挙げることができる。またオリゴ糖類としては、通常2糖類から6糖類までのものが含まれるが、具体的にはショ糖、マルトース、乳糖、トレハロース、マルトトリオース等を挙げることができる。糖アルコール類としては具体的には、ソルビトール、マルチトール、マンニトール、エリスリトール、キシリトール、オリゴ糖アルコール等を挙げることができる。
各種粉末食品として、ココアパウダー、粉乳、果実粉末、果汁粉末、生クリーム粉末、チーズ粉末、コーヒー粉末、ヨーグルト粉末等が例示できる。
本発明の高融点油脂成分としては、パーム油の極度硬化油、大豆油の極度硬化油、米ぬか油の極度硬化油、低エルシン酸の菜種油の極度硬化油、高エルシン酸の菜種油の極度硬化油等が例示できる。融点が55℃以上のものが好ましい。55℃より低い場合は起泡力が弱くなると共に、気泡の保持力も弱くなる。高融点油脂成分の割合は、起泡性チョコレート類に対して0.5〜5重量%であるのが好ましく、より好ましくは1〜3重量%であるのが良い。添加方法については特に限定されるものではない。高融点油脂成分の割合が下限未満の場合は起泡力が弱くなると共に、気泡の保持力も弱くなる。上限を超える場合は、効果は認められるが十分ではなく口どけも悪いものになってしまう。
本発明の非高融点油脂成分の主要成分が20℃で液状の油脂又は/及びラウリン系油脂であるのが好ましい。20℃で液状の油脂としては、大豆油、綿実油、コーン油、サフラワー油、オリーブ油、菜種油、米ぬか油、パームスーパーオレインやこれらの微水添油等の単独又は組み合わせた油脂が例示できる。ラウリン系油脂としては、主要構成脂肪酸がラウリン酸であるヤシ油、パーム核油、ババス油等周知のラウリン系油脂、及びこれらのラウリン系油脂の分別油等が例示できる。
本発明の起泡性チョコレート類の製造法としては、高融点油脂成分、非高融点油脂成分及び糖類を必須成分とし、必要によりカカオマスやココアパウダー、粉乳等の各種粉末食品、乳化剤、香料、色素等の中から選択した原料を任意の割合で混合し、ロール掛け及びコンチング処理を行い、チョコレート類生地を溶融状態から急冷固化することにより得ることができる。
好ましくは、急冷固化させる温度が起泡性チョコレート類の品温を38℃以下、より好ましくは25℃以下であるのが良い。品温が38℃を超えて徐冷した場合は、起泡性チョコレート類の起泡力が弱くなり、ホイップタイムも長くなる。これは起泡性チョコレート類中の高融点油脂成分の油脂結晶の起泡力及び気泡安定化力が弱くなるためと推察される。
上記方法で得られた起泡性チョコレート類は、攪拌できる程度の状態に調製し、例えば33℃付近に温調して各種ホイップ器具にてホイップし、気泡チョコレートを得ることができる。
本発明で得られた気泡チョコレートは、冷菓又は冷蔵菓子のコーティング材及び/又は練り込み材として使用することができる。冷菓としては、具体的には、アイスクリーム、アイスミルク、ラクトアイス、氷菓等が例示できる。冷蔵菓子としては、シュー、エクレア、ケーキ、ヨーグルト、ババロア、ゼリー等が例示できる。

冷蔵、冷凍用途に利用できる気泡安定性に優れた気泡チョコレートを得ることが出来る起泡性チョコレート類及びその製造法を提供することが可能になったのである。TECHNICAL FIELD The present invention relates to foamable chocolates and a method for producing foamable chocolates. In detail, foamable chocolates with excellent bubble stability that can be used for refrigeration and freezing applications, the melting point of the high-melting oil component in the chocolates and the melting point of the components excluding the high-melting oil component in the chocolates The present invention relates to foamable chocolates having a temperature difference of 30 ° C or more.
BACKGROUND ART In recent years, diversification of chocolate products has progressed, and among them, aerated chocolate is establishing a category. Examples of the method for aerating chocolates include a method in which an emulsifier is added to chocolate dough and foaming is performed (Japanese Unexamined Patent Publication No. 1-144934), and a fat or oil containing triglycerides having a total of 58 or more carbon atoms in constituent fatty acid residues. Is blended in chocolate dough, the bubbles are stabilized by the fat crystals, and the specific gravity of the chocolate dough is lowered (Japanese Patent Laid-Open No. Hei 3-201946). There is known a method in which the chocolate is put into a container, the chocolate is expanded under reduced pressure, and the whole is hardened (JP-A-6-62742).
However, these products contain air bubbles in chocolate dough containing cocoa mass and cocoa butter as a main component, and their uses are limited.
DISCLOSURE OF THE INVENTION An object of the present invention is to provide foamable chocolates having excellent bubble stability that can be used for refrigeration and freezing, and a method for producing the same.
The present inventors have conducted intensive studies in order to solve the above problems, and as a result, completed the present invention.
That is, the high melting point fat component in the chocolate and the foaming chocolate and the high melting point fat component in the chocolate having a temperature difference of 30 ° C. or more between the melting points of the components excluding the high melting point fat component in the chocolates. A method for producing foamable chocolate, comprising rapidly cooling and solidifying a foamable chocolate dough having a temperature difference of 30 ° C. or more from the melting point of components other than the high melting point fat component in chocolate from a molten state. It is.
BEST MODE FOR CARRYING OUT THE INVENTION Chocolate in the present invention has fats and oils and sugars as essential components, and is selected from various powdered foods such as cacao mass and cocoa powder, milk powder, emulsifiers, flavors, pigments and the like as necessary. It means a material obtained by mixing the raw materials obtained in an arbitrary ratio, rolling and conching by a conventional method. Specific examples of fats and oils include soybean oil, cottonseed oil, corn oil, safflower oil, olive oil, palm oil, rapeseed oil, rice bran oil, sesame oil, kapok oil, coconut oil, palm kernel oil, babassu oil, cocoa butter, and milk fat. , Lard, fish oil, whale oil and other various animal and vegetable oils and fats, and their hardened oils, fractionated oils, transesterified oils and the like.
Examples of the saccharide include monosaccharides, oligosaccharides, sugar alcohols, dextrin, starch syrup, and the like. Specific examples of the monosaccharide include glucose, fructose, mannose and xylose. Oligosaccharides usually include disaccharides to hexasaccharides, and specific examples include sucrose, maltose, lactose, trehalose, and maltotriose. Specific examples of sugar alcohols include sorbitol, maltitol, mannitol, erythritol, xylitol, oligosaccharide alcohol, and the like.
Examples of various powdered foods include cocoa powder, milk powder, fruit powder, fruit juice powder, fresh cream powder, cheese powder, coffee powder, yogurt powder, and the like.
As the high melting point oil component of the present invention, extremely hardened oil of palm oil, extremely hardened oil of soybean oil, extremely hardened oil of rice bran oil, extremely hardened oil of rapeseed oil of low erucic acid, extremely hardened oil of rapeseed oil of high erucic acid Etc. can be exemplified. Those having a melting point of 55 ° C. or higher are preferred. When the temperature is lower than 55 ° C., the foaming power is weakened, and the holding power of air bubbles is also weakened. The proportion of the high melting point fat component is preferably 0.5 to 5% by weight, more preferably 1 to 3% by weight, based on the foamable chocolates. The method of addition is not particularly limited. When the proportion of the high melting point fat component is less than the lower limit, the foaming power is weakened, and the holding power of air bubbles is also weakened. When the amount exceeds the upper limit, the effect is recognized but is not sufficient, and the taste becomes poor.
It is preferable that the main component of the non-high melting point fat and oil component of the present invention is a fat and / or lauric fat which is liquid at 20 ° C. Examples of the fats and oils which are liquid at 20 ° C. include soybean oil, cottonseed oil, corn oil, safflower oil, olive oil, rapeseed oil, rice bran oil, palm super olein, and oils and fats used alone or in combination thereof. Examples of the laurin-based fats and oils include well-known laurin-based fats and oils such as coconut oil, palm kernel oil, and babass oil whose main constituent fatty acid is lauric acid, and fractionated oils of these laurin-based fats and oils.
The method for producing the foamable chocolates of the present invention includes a high-melting oil component, a non-high-melting oil component and saccharides as essential components, and, if necessary, cocoa mass and cocoa powder, various powdered foods such as milk powder, emulsifiers, flavors, and pigments. Raw materials selected from the above are mixed at an arbitrary ratio, rolled and conched, and the chocolate material is rapidly cooled and solidified from a molten state.
Preferably, the temperature for quenching and solidifying the foamable chocolate is 38 ° C. or less, more preferably 25 ° C. or less. When the product temperature is gradually cooled to over 38 ° C., the foaming power of the foamable chocolates is weakened, and the whipping time is long. This is presumed to be because the foaming power and foam stabilizing power of the fat crystals of the high melting point fat component in the foamable chocolates are weakened.
The foamable chocolates obtained by the above method are prepared in such a state that they can be agitated, and the temperature is adjusted to, for example, about 33 ° C. and whipped with various whipping instruments to obtain foamed chocolate.
The aerated chocolate obtained in the present invention can be used as a coating material and / or a kneading material for frozen desserts or chilled confections. Specific examples of the frozen dessert include ice cream, ice milk, lacto ice, frozen dessert and the like. Examples of chilled confectionery include shoe, eclair, cake, yogurt, bavarois, jelly, and the like.
EXAMPLES Hereinafter, the present invention will be described in more detail by showing examples of the present invention, but the spirit of the present invention is not limited to the following examples. In addition, in an example, all% and a part mean a weight basis.
The melting point was measured in accordance with the method specified in 2.2.4.3 Softening point (ring and ball method) of the Japan Oil Chemistry Association Standard Oil and Fat Analysis Test Method (1996 edition).
Example 1
The whole raw materials of the chocolates of Formulation 1 were mixed for 0.5 hours while heating to 70 ° C. This was rolled and flaked into particles having an average particle size of 20 microns. After conching the obtained flakes at 65 ° C. for 2 hours using a conche, 1 kg of the prototype chocolates were filled in a can and rapidly cooled and solidified in a refrigerator at 5 ° C. for 1 day. The next day, the temperature was adjusted in a 50 ° C incubator for one day. Thereafter, the mixture was cooled to 33 ° C. by manual stirring and whipped with a Kenwood mixer. The conditions of whipping were as follows: 300 g of the above chocolates, whipped product temperature of 30 to 33 ° C., and the stirring speed was the highest. When whipping was performed under the above conditions, the whipping time was 30 minutes and the specific gravity was 0.68. When the obtained aerated chocolate (product temperature 31 ° C) was coated on an ice bar (commercially available), a chocolate coating with a fluffy whip feeling was formed at a dry weight of 90 seconds when left at a room weight of 24g and room temperature of 20 ° C. Was. In addition, the foam chocolate coating cured overnight at -20 ° C had a crisp texture.
Figure 2002076225
The melting point of the chocolates was determined to be 24 ° C. by measuring the melting point of the chocolates in the same ratio except for the extremely hardened palm oil from the raw material blend of NO1 and chocolate. The melting point of extremely hardened palm oil was 58 ° C.
Example 2
Same as Example 1 except that in the formulation of Example 1, 17.5 parts of palm kernel olein and 2.0 parts of extremely hardened palm oil were replaced with 15.5 parts of palm kernel olein and 4.0 parts of extremely hardened palm oil.
