【発明の属する技術分野】
本発明は、センター材の表面に含気泡チョコレートが被覆され、被覆された表面がライチ様表面のような凹凸である含気泡チョコレート被覆菓子及びその製造法に関する。
【0002】
【従来の技術】
最近、チョコレートを他の菓子類例えばビスケットのような焼き菓子と組み合わせることにより食感を軽くしたような商品、さらには含気泡チョコレートと他の菓子類を組み合わせることでさらに食感を軽くしたような商品も市販されている。チョコレートの食感を軽くする目的でチョコレート生地に気泡を含ませる方法としては、例えばチョコレートを先ず攪拌した後、減圧下に置くことで比重を低下させる方法(特開昭62―275648号公報、特開昭63―202341号公報)や加圧した気体をチョコレート生地に含ませ、常圧に戻すことによりチョコレート生地の比重を下げる方法(特開昭62―58955号公報、特開昭63―49040号公報)、或いは乳化剤により起泡する方法(特開平1―144934号公報、特開平5―211842号公報)、起泡したショートニングとチョコレート生地を混合しチョコレート生地の比重を下げる方法(特開昭63―28355号公報)等が提案されている。
【0003】
また従来より、回転被覆装置を用いて、その回転容器内にナッツのようなセンター材を入れ、センター材を回転しながら溶融したチョコレートを散布しセンター材の表面をチョコレートで被覆することが行われており、製品として多数のチョコレート被覆菓子が市販されている。このようなチョコレート被覆菓子はいずれも被覆されたチョコレート表面が概ね均一で、艶を有するものであり、センター材にパフ、ゼリー、乾燥フルーツ等を採用しているが、外観はどれも同じで変化に乏しいものであった。
新規な菓子として表面に油脂組成物で形成される突起状の角を持つ油脂性被覆菓子およびその製造法(特開2000−210023号公報)が提案されている。故意にチョコレート表面を凹凸にすることによって、被覆された中身に興味を抱くような外観を呈した含気泡チョコレート被覆菓子はこれまでに見出されていない。
【0004】
【発明が解決しようとする課題】
本発明は、センター材の表面に含気泡チョコレートが被覆され、被覆された表面がライチ様表面のような凹凸である状態に被覆することにより、軽い食感と変化に富んだ外観を有する含気泡チョコレート被覆菓子及びその製造法を提供することを目的とする。
【0005】
【課題を解決するための手段】
本発明は、如上の点に鑑み鋭意研究した結果、センター材を転動させながら、溶融した含気泡チョコレートをふりかけ、センター材表面で固化させつつ溶融した含気泡チョコレートをふりかけて被覆することにより含気泡チョコレート被覆菓子を容易に製造することができるとの知見を得、本発明を完成するに至った。
即ち、本発明の第1は、回転被覆装置を用いてセンター材の表面に比重が0.5〜1.05の範囲であり、食用油脂とべへン酸を含有するトリ飽和脂肪酸グリセリドとの混合油を含む、含気泡チョコレートが被覆され、被覆された表面がライチ様表面のような凹凸であることを特徴とする含気泡チョコレート被覆菓子である。第2は、べへン酸を含有するトリ飽和脂肪酸グリセリドの飽和脂肪酸中のベヘン酸が30%以上である、第1記載の含気泡チョコレート被覆菓子である。第3は、食用油脂とべへン酸を含有するトリ飽和脂肪酸グリセリドの混合比率が85:15〜95:5である、第1又は第2記載の含気泡チョコレート被覆菓子である。第4は、べへン酸を含有するトリ飽和脂肪酸グリセリドの含量が、含気泡チョコレート全量に対して0.5〜2重量%である、第1乃至第3の何れか1に記載の含気泡チョコレート被覆菓子である。第5は、回転被覆装置を用いてセンター材を転動させながら、比重が0 . 5〜1 . 05の範囲であり、食用油脂とベヘン酸を含有するトリ飽和脂肪酸グリセリドとの混合油を含む、溶融した含気泡チョコレートを、センター材表面で固化させつつふりかけて被覆することを特徴とする表面がライチ様表面のような凹凸を有する含気泡チョコレート被覆菓子の製造法である。
【0006】
【発明の実施の形態】
本発明におけるセンター材は特に限定されるものではなく、例えばコーンパフ、ライスパフ等のパフ類、ビスケット、プレッツェルなどの焼物類、乾燥したフルーツ類、ゼリー、ヌガーなどのキャラメル類、ナッツ類、マシュマロ等が例示できる。含気泡チョコレートとの食感の相性の点で歯ざわりの軽いものが好ましい。また、このようなセンター材は、その形状が球形ないし卵形を呈しているものが好ましい。
【0007】
本発明における含気泡チョコレートは、以下の方法で得られるものであれば良く特に限定されるものではない。例えばチョコレートを先ず攪拌した後、減圧下に置くことで比重を低下させる方法、或いは乳化剤により起泡する方法、起泡したショートニングとチョコレート生地を混合しチョコレート生地の比重を下げる方法、食用油脂とベヘン酸を含有するトリ飽和脂肪酸グリセリドの混合油をトリ飽和脂肪酸グリセリドの結晶存在下でチョコレート生地に添加し比重を下げる方法等が例示できる。好ましくは食用油脂とベヘン酸を含有するトリ飽和脂肪酸グリセリドの混合油をトリ飽和脂肪酸グリセリドの結晶存在下でチョコレート生地に添加し比重を下げることが好ましく、更にべへン酸を含有するトリ飽和脂肪酸グリセリドの飽和脂肪酸中のベヘン酸が30%以上であることが結晶状態をより安定化する点で好ましい。べへン酸を含有するトリ飽和脂肪酸グリセリドが結晶状態で存在することが好ましく、これによりべへン酸を含有するトリ飽和脂肪酸グリセリドは他の油脂、例えばチョコレート生地中のココアバター等と相互作用しないためチョコレートの口溶けを悪くしない。しかし、完全に融解した状態で使用した場合には、含気するために必要な結晶量が無くなり含気機能が低下するだけでなく、チョコレート生地中のココアバター等と相互作用するためチョコレートの口溶けを悪くする。このためチョコレート生地の品温は25℃〜40℃の範囲に温度調整することが好ましく、又食用油脂とべへン酸を含有するトリ飽和脂肪酸グリセリドの混合油も同様に温度調整し、これらを混合してホイップ、含気泡する。但し、テンパリング型のチョコレート生地を使用するときには、テンパリングを行ったチョコレートのテンパリングが壊れない温度例えば31℃で混合し、分散する事が可能である。
【0008】
本発明におけるセンター材に被覆された含気泡チョコレートの比重は0.5〜1.05の範囲、好ましくは0.6〜0.9の範囲の比重がよい。1.05を超えると従来のチョコレート被覆菓子との差別化が不明確となり、食感を軽くすることは出来ない。逆に比重が0.5未満であると食感は非常に軽くなるが、気泡をかなり含む為含気泡チョコレートの流動性が無くなり、センター材を被覆するのが難しくなる。なお比重の測定については、含気泡チョコレートを調製した際の比重の測定法とセンター材及びセンター材に被覆された含気泡チョコレートの比重の測定法は異なる。前者は容器に含気泡チョコレートを充填して内容物の重量を測定し、かわりに水を充填したときの水の重量で除して算出する方法を採用し、後者は菜種置換法によりその体積を求め、そのものの重量を測定し算出する方法を採用した。
【0009】
本発明の含気泡チョコレート被覆菓子の製造法としては、上記センター材に上記含気泡チョコレートを被覆するのであるが、センター材を被覆する方法は、センター材を転動させながら、溶融した含気泡チョコレートをふりかけ、センター材表面で固化させつつ溶融した含気泡チョコレートをふりかけて被覆することにより、センター材の表面に含気泡チョコレートが被覆され、被覆された表面がライチ様表面のような凹凸である含気泡チョコレート被覆菓子を得ることができる。センター材を転動させながら含気泡チョコレートを被覆する装置としては、通常回転被覆装置にて行うのが簡便である。回転容器内にセンター材を入れて転動させながら、回転容器内に冷風を吹き込みながら溶融した含気泡チョコレートを被覆していく。
本発明においては、回転被覆装置を用いる場合は、通常のチョコレートを被覆する場合に比べて、概ね半分程度に回転速度を落とし、溶融した含気泡チョコレートをセンター材にふりかけ、センター材表面で固化させつつ溶融した含気泡チョコレートをふりかけて被覆するという方法で被覆される。つまり、溶融した含気泡チョコレートをセンター材にふりかけたら、冷風をあてつつ被覆菓子自身の重量にてゆっくり回転させることにより表面のみを固化させる。そして、被覆菓子がバラけ始めた時点で次の溶融した含気泡チョコレートをふりかけるという作業を繰り返し目標の厚さまで被覆する。含気泡チョコレートの比重を上昇させないように抑制しつつセンター材を転動させるのが好ましい。このような回転被覆装置を使用した場合、このような被覆作業により含気泡チョコレートの比重はセンター材の種類により少し変わるが若干上昇する。従来のチョコレート被覆菓子では、十分に回転させることによってチョコレートを均一に被覆していき、凹凸の無い滑らかで艶のある表面を目標としていた。そのため、従来の被覆菓子では、この後表面にシロップがけをしてさらに艶をだし、シェラックを掛けて仕上げる。しかし、本発明の含気泡チョコレート被覆菓子では上記の方法により、被覆された表面がライチ様表面のような凹凸である状態の含気泡チョコレート被覆菓子を得ることができる。表面に凹凸があることにより食感、形状に特徴があるためこの後の工程例えば、シロップ掛け、シェラック掛けは行わない方が好ましい。より好ましくは、目標の厚さになった後十分な冷風を吹き付けて表面を冷却した後も、あまり回転容器中で回転させない方が食感、形状において良好のものが得られる。被覆作業時の回転速度が速すぎると被覆した含気泡チョコレートの気泡の合一、脱気が起こりやすくなり凹凸のある形状が得難いばかりか、食感も従来のチョコレート被覆菓子とかわらないものとなってしまう。
【0010】
含気泡チョコレートの被覆層の厚みは任意であるが、センター材としてパフ類を用いた場合、被覆層を厚くした方が好ましく、概ね3mm程度にするのが良好である。例えば、直径20mm程度の球形のコーンパフをセンター材として用いた場合、含気泡チョコレートの割合は、コーンパフ1重量部に対して含気泡チョコレート6重量部程度の割合が適当である。この含気泡チョコレート層の厚さは、センター材の種類により任意に変化させればよく、センター材の持ち味を活かせる割合を実験的に確かめて決定するのが好ましい。
【0011】
本発明において食用油脂とは、大豆油、菜種油、コーン油、綿実油、落花生油、ひまわり油、こめ油、ベニバナ油、サフラワー油、オリーブ油、ゴマ油、パーム油、ヤシ油、パーム核油等の植物油脂や牛脂、豚脂、魚油、鯨油、乳脂等の動物油脂、及びこれらを分別、水素添加、エステル交換等を施した加工油脂の単品又は、これらの組み合わせでもよい。20℃で液状の油脂とベヘン酸を含有するトリ飽和脂肪酸グリセリドの混合油をチョコレート生地に添加して含気する際、ベヘン酸を含有するトリ飽和脂肪酸グリセリドが結晶状態でも広い温度帯において流動性を有しているので作業性が向上する。
または、好ましくはハードバター例えば、カカオ脂、カカオ代用脂等のテンパリング型油脂、エライジン酸を構成脂肪酸とするトランス型ハードバターを使用するのが良い。ハードバターとベヘン酸を含有するトリ飽和脂肪酸グリセリドの混合油をチョコレート生地に添加し攪拌して得られる含気泡チョコレート類の耐熱性が向上する。
【0012】
本発明においてトリ飽和脂肪酸グリセリドとしては、トリグリセリドの構成脂肪酸がすべて飽和脂肪酸よりなるトリグリセリドである。トリ飽和脂肪酸グリセリドは、油脂を水素添加などにより沃素価を1以下あるいは構成脂肪酸グリセリド中の二重結合がほとんどない脂肪酸組成にした油脂、たとえば極度硬化油を用いることができる。
【0013】
本発明においてベヘン酸を含有するトリ飽和脂肪酸グリセリドとは、例えばエルシン酸を30%以上含む油脂を通常の水素添加により沃素価1以下、融点60℃以上に精製加工したものであり、エルシン酸を30%以上含む油脂としては高エルシン酸の菜種油、からし油、クランベ油、うぜんばれん種子油等が挙げられるが、容易に入手可能な高エルシン酸の菜種油が好ましい。
【0014】
本発明においては上記食用油脂とベヘン酸を含有するトリ飽和脂肪酸グリセリドの混合油を調製する際の混合比率は、85:15〜95:5であるのが好ましい。
【0015】
本発明では食用油脂とトリ飽和脂肪酸グリセリドの混合油をトリ飽和脂肪酸グリセリドの結晶存在下でチョコレート類に添加する場合、当該トリ飽和脂肪酸グリセリドが最終的に含気泡チョコレート類中に0.5〜2重量%、好ましくは1〜2重量%の範囲となるように添加することが好ましい。これより添加が多い場合、油脂の融点が高くなり過ぎ、含気はするものの含気途中でチョコレートの粘度増加が激しく、ホイップ時の温度によっては含気途中に固化してしまう。さらに含気できたとしても含気泡チョコレートとしては、耐熱性は付与されるが、非常に口溶けの悪いものとなり、菓子としての商品価値も下がる。逆にこれより添加量が少ない場合、含気が不十分になり好ましくない。
【0016】
本発明では食用油脂とべへン酸を含有するトリ飽和脂肪酸グリセリドの混合油を完全に融解した後、混合油の品温を30℃〜45℃まで冷却し結晶を析出させて調製した油脂を使用するのが良い。そのことによって、ベへン酸を含有するトリ飽和脂肪酸グリセリドの結晶がそれより融点の低い低融点油脂中に分散させてなる油脂組成物がえられ、これは含気機能を付与する添加物として好適に用いることができる。食用油脂とベヘン酸を含有するトリ飽和脂肪酸グリセリドの混合油脂を完全に融解した後、オンレーター等の練りを加えることの出来る装置を用いて、品温を30℃〜45℃まで冷却し結晶を析出させた後、冷却させて調製することができる。これ以外の方法たとえば単純に室温に放置して徐冷却した場合では結晶のサイズが大きくなり過ぎチョコレートを含気させるには不向きとなる。
【0017】
本発明の含気泡チョコレートを調製するのに使われるチョコレート生地は、油脂成分がココアバターのみから成る、いわゆる規約乃至法規上に規定されたチョコレートの生地のみを指すのではなく、通常、ココアバターの代わりに使用されるココアバター代用脂としてのハードバタ一を使用した各種のチョコレート類の生地をも含むものである。したがって、スイートチョコレートあるいはミルクチョコレート等従来公知の市販されているチョコレート自体は勿論のこと、カカオマス、ココアパウダー、ココアバターあるいはハードバター等の一種または二種以上を使用してその他の原料とともに常法どおりロール掛け、コンチング処理して得たチョコレート生地を使用することができる。また、本発明においてココアまたはカカオマスを使用せずココアバターあるいはハードバターと砂糖、全脂粉乳または脱脂粉乳等の固形分を使用することによって得られるホワイトチョコレート類を使用することもでき、さらにコーヒーやフルーツ等の風味剤と併用して様々な風味、色調を呈したカラーチョコレートを使用することもできる。
【0018】
本発明において、本発明の効果を損なわない程度に、周知の乳化剤、例えばレシチン、リゾレシチン、グリセリン脂肪酸エステル、庶糖脂肪酸エステル、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ート酸エステル等を使用することができる。また、以上の原材料の他に、リン酸塩、ガム類、糖類等を適宜添加使用してもよい。
【0019】

[0006]
DETAILED DESCRIPTION OF THE INVENTION
The center material in the present invention is not particularly limited, and examples thereof include puffs such as corn puffs and rice puffs, baked goods such as biscuits and pretzels, dried fruits, caramels such as jelly and nougat, nuts, marshmallows and the like. It can be illustrated. The thing with a light texture is preferable at the point of compatibility with a foam-containing chocolate. Further, such a center material preferably has a spherical or oval shape.
[0007]
The foamed chocolate in the present invention is not particularly limited as long as it is obtained by the following method. For example, after first stirring the chocolate, the specific gravity is reduced by placing it under reduced pressure, or the method of foaming with an emulsifier, the method of mixing the foamed shortening with the chocolate dough to lower the specific gravity of the chocolate dough, edible fat and behen Examples thereof include a method of reducing the specific gravity by adding a mixed oil of trisaturated fatty acid glycerides containing acid to chocolate dough in the presence of crystals of trisaturated fatty acid glycerides. It is preferable to add a mixed oil of edible oil and fat and trisaturated fatty acid glyceride containing behenic acid to the chocolate dough in the presence of crystals of trisaturated fatty acid glyceride to lower the specific gravity, and further trisaturated fatty acid containing behenic acid It is preferable that behenic acid in the saturated fatty acid of glyceride is 30% or more from the viewpoint of further stabilizing the crystalline state. Preferably, trisaturated fatty acid glycerides containing behenic acid are present in a crystalline state, so that the trisaturated fatty acid glycerides containing behenic acid interact with other fats and oils such as cocoa butter in chocolate dough Because it does not, do not worsen the melting of chocolate. However, when it is used in a completely melted state, the amount of crystals necessary for aeration is lost and the aeration function is lowered.In addition, it interacts with cocoa butter in the chocolate dough, so it melts in the mouth of chocolate. Make it worse. For this reason, it is preferable to adjust the temperature of the chocolate dough to a range of 25 ° C. to 40 ° C., and also adjust the temperature of the mixed oil of edible fats and oils and trisaturated fatty acid glycerides containing behenic acid and mix them. Then whip and contain air bubbles. However, when using a tempering-type chocolate dough, it is possible to mix and disperse at a temperature at which the tempering of the tempered chocolate does not break, for example, 31 ° C.
[0008]
The specific gravity of the foamed chocolate covered with the center material in the present invention is in the range of 0.5 to 1.05, preferably in the range of 0.6 to 0.9. If it exceeds 1.05, differentiation from the conventional chocolate-coated confectionery becomes unclear, and the texture cannot be reduced. On the contrary, if the specific gravity is less than 0.5, the texture becomes very light, but since the foam contains a lot of bubbles, the fluidity of the foamed chocolate is lost and it becomes difficult to coat the center material. In addition, about the measurement of specific gravity, the measuring method of the specific gravity at the time of preparing foamed chocolate differs from the measuring method of the specific gravity of the foamed chocolate coat | covered with the center material and the center material. The former employs a method of filling the container with foamed chocolate and measuring the weight of the contents, and dividing by the weight of the water when filled with water instead, and the latter adopts the method of calculating the volume by the rapeseed substitution method. The method of obtaining and measuring the weight of the product itself was adopted.
[0009]
As the method for producing the cell-containing chocolate-coated confectionery of the present invention, the above-mentioned center material is coated with the above-mentioned cell-containing chocolate. The method of coating the center material is a melted cell-containing chocolate while rolling the center material. By covering the center material surface with the foamed chocolate, the surface of the center material is covered with the foamed chocolate, and the coated surface is uneven, such as a lychee-like surface. A bubble chocolate-coated confectionery can be obtained. As an apparatus for coating the cell-containing chocolate while rolling the center material, it is usually easy to carry out with a rotary coating apparatus. While the center material is put in the rotating container and rolled, the melted bubble-containing chocolate is coated while blowing cold air into the rotating container.
In the present invention, when using a rotation coating device, the rotation speed is reduced to about half compared to the case of coating ordinary chocolate, and the melted bubble-containing chocolate is sprinkled on the center material and solidified on the surface of the center material. It is coated by a method of sprinkling and covering the melted foamed chocolate. That is, when the melted bubble-containing chocolate is sprinkled on the center material, only the surface is solidified by slowly rotating with the weight of the coated confectionery itself while applying cold air. Then, when the coated confection starts to break, the operation of sprinkling the next melted bubble-containing chocolate is repeated until the target thickness is reached. It is preferable to roll the center material while suppressing the specific gravity of the bubble-containing chocolate from increasing. When such a rotary coating apparatus is used, the specific gravity of the cellulosic chocolate slightly increases depending on the type of the center material due to such a coating operation. In the conventional chocolate-coated confectionery, the chocolate is uniformly coated by sufficiently rotating, and the target is a smooth and glossy surface without unevenness. Therefore, in the conventional coated confectionery, after this, the surface is syruped to further gloss, and the shellac is applied to finish. However, in the foamed chocolate-coated confectionery of the present invention, the foamed chocolate-coated confectionery in which the coated surface is uneven like a lychee-like surface can be obtained by the above method. Since the texture and shape are characterized by unevenness on the surface, it is preferable not to perform subsequent steps such as syrup application or shellac application. More preferably, after the target thickness is reached, the surface is cooled by blowing a sufficient amount of cold air, so that it is possible to obtain a better texture and shape if the surface is not rotated in a rotating container. If the rotational speed during the coating operation is too fast, the air bubbles in the covered foamed chocolate will be coalesced and degassed easily, making it difficult to obtain an uneven shape, and the texture will not be different from the conventional chocolate coated confectionery. End up.
[0010]
Although the thickness of the coating layer of the foamed chocolate is arbitrary, when puffs are used as the center material, it is preferable to increase the thickness of the coating layer, and it is preferable to make the thickness approximately 3 mm. For example, when a spherical corn puff having a diameter of about 20 mm is used as the center material, the ratio of the bubble-containing chocolate is appropriately about 6 parts by weight of the bubble-containing chocolate with respect to 1 part by weight of the corn puff. The thickness of the bubble-containing chocolate layer may be arbitrarily changed depending on the type of the center material, and it is preferable to experimentally confirm and determine the ratio at which the center material can be used.
[0011]
In the present invention, edible fats and oils are plants such as soybean oil, rapeseed oil, corn oil, cottonseed oil, peanut oil, sunflower oil, rice bran oil, safflower oil, safflower oil, olive oil, sesame oil, palm oil, palm oil, palm kernel oil and the like. Fats, beef tallow, pork tallow, fish oil, whale oil, milk fat and other animal fats and oils, processed oils obtained by separation, hydrogenation, transesterification, etc., or combinations thereof may be used. When a mixed oil of trisaturated fatty acid glycerides containing liquid fats and behenic acid at 20 ° C. is added to the chocolate dough, the trisaturated fatty acid glycerides containing behenic acid are fluid in a wide temperature range even in the crystalline state. As a result, workability is improved.
Alternatively, it is preferable to use hard butter, for example, tempering type fats and oils such as cacao butter and cacao substitute fat, and trans hard butter having elaidic acid as a constituent fatty acid. The heat resistance of the foamed chocolate obtained by adding a mixed oil of trisaturated fatty acid glyceride containing hard butter and behenic acid to the chocolate dough and stirring is improved.
[0012]
In the present invention, the tri-saturated fatty acid glyceride is a triglyceride in which all of the constituent fatty acids of the triglyceride are saturated fatty acids. As the tri-saturated fatty acid glycerides, fats and oils having an iodine value of 1 or less or a fatty acid composition having almost no double bonds in the constituent fatty acid glycerides by hydrogenation or the like, such as extremely hardened oils, can be used.
[0013]
In the present invention, trisaturated fatty acid glycerides containing behenic acid are, for example, oils and fats containing 30% or more of erucic acid that are refined and processed to have an iodine value of 1 or less and a melting point of 60 ° C. or more by ordinary hydrogenation. Examples of oils and fats containing 30% or more include rapeseed oil with high erucic acid, mustard oil, clambe oil, and sesame seed oil, and rapeseed oil with high erucic acid that is readily available is preferred.
[0014]
In this invention, it is preferable that the mixing ratio at the time of preparing the mixed oil of the said edible fat and oil and the tri saturated fatty acid glyceride containing behenic acid is 85: 15-95: 5.
[0015]
In the present invention, when a mixed oil of edible fats and oils and trisaturated fatty acid glycerides is added to chocolates in the presence of crystals of trisaturated fatty acid glycerides, the trisaturated fatty acid glycerides are finally added to the foamed chocolates in an amount of 0.5 to 2. It is preferable to add so that it may become the range of weight%, Preferably it is 1-2 weight%. When the amount of addition is larger than this, the melting point of the oil becomes too high, and although it is aerated, the viscosity of the chocolate increases sharply during the aeration, and solidifies during the aeration depending on the temperature during whipping. Even if it can be aerated, the foamed chocolate is provided with heat resistance, but is very poorly melted in the mouth, and the commercial value as a confectionery is also reduced. On the other hand, when the addition amount is smaller than this, the air content becomes insufficient, which is not preferable.
[0016]
In the present invention, an oil and fat prepared by completely melting a mixed oil of edible fat and behenic acid and containing a trisaturated fatty acid glyceride and then cooling the product temperature of the mixed oil to 30 ° C to 45 ° C to precipitate crystals. Good to do. As a result, an oil / fat composition in which crystals of trisaturated fatty acid glycerides containing behenic acid are dispersed in a low-melting oil / fat having a lower melting point is obtained. It can be used suitably. After completely melting the mixed fat and oil of edible fat and trisaturated fatty acid glyceride containing behenic acid, the product temperature is cooled to 30 ° C to 45 ° C using a device that can be kneaded, such as an onrator, and the crystal It can be prepared by cooling after precipitation. In other methods, for example, when the solution is simply left at room temperature and slowly cooled, the size of the crystals becomes too large to be suitable for aeration of chocolate.
[0017]
The chocolate dough used to prepare the foamed chocolate of the present invention is not only a chocolate dough defined by the so-called rules or regulations, in which the fat and oil component consists only of cocoa butter. It includes various chocolate doughs using hard butter as a substitute for cocoa butter. Therefore, as well as conventionally known commercially available chocolate such as sweet chocolate or milk chocolate, cocoa mass, cocoa powder, cocoa butter or hard butter is used in combination with other ingredients as usual. Chocolate dough obtained by rolling and conching can be used. Further, in the present invention, white chocolate obtained by using cocoa butter or hard butter and a solid content such as sugar, whole milk powder or skim milk powder without using cocoa or cacao mass can be used. Colored chocolates with various flavors and colors can be used in combination with flavoring agents such as fruits.
[0018]
In the present invention, well-known emulsifiers such as lecithin, lysolecithin, glycerin fatty acid ester, sucrose fatty acid ester, fatty acid ester, polyglycerin fatty acid ester, polyglycerin condensed ricinoleate and the like are used to the extent that the effects of the present invention are not impaired. Can do. In addition to the above raw materials, phosphates, gums, saccharides and the like may be appropriately added and used.
