【産業上の利用分野】
本発明は、液体に溶解した際に液体上部にカプチーノ様の泡の層を形成する発泡性粉末飲料に関する。
【0002】
【従来の技術】
カプチーノ、カフェラテなどの発泡性飲料においては、その液体上部に形成される泡の層の量および持続性が品質上の重要な要素となる。また、これらの発泡性飲料を粉末化したものを湯などの液体に溶解し飲用する際には、溶解性にすぐれる、容易に発泡するなど調製が簡便であることが重要である。さらに、発泡性粉末飲料を製造するにおいては、工程が単純であることが望ましい。
【0003】
従来提案されている発泡性粉末飲料の発泡の手段には、振蘯によるもの、ガス含有発泡性クリーミングパウダーによるもの、炭酸塩と酸の反応により二酸化炭素を発生させることによるものがある。振蘯によるものには、特開2000−270818、特開2000−157232、特開平10−295339があるが、これらは容器に充填した後振蘯する必要があり、飲用時の調製が煩雑である。
【0004】
ガス含有発泡性クリーミングパウダーによるものには、特表平11−503920があるが、ガス含有発泡性クリーミングパウダーのみでは発泡量が少なく、泡の持続性が低いなどの問題がある。
【0005】
酸と炭酸塩の反応により二酸化炭素を発生させることによるものには、特開平10−066531があるが、製造方法が複雑となる。発泡性粉末飲料の製造においては、溶解性を向上させるために造粒を行うことが一般的であるが、この際のバインダー中の水に炭酸塩および酸が溶解し反応する。反応は速やかに終了し、完成した製品は発泡しないものとなる。これを避けるために、酸を含有する部分と炭酸塩を含有する部分を別々に造粒する必要があることがその理由である。また、酸と炭酸塩の反応により二酸化炭素を発生させるだけでは、泡の持続性が低いなどの問題がある。
【0006】
従来提案されている発泡性粉末飲料の泡の持続性を向上させる手段には、特開平9−163969のホップ抽出物を添加する方法、特開2001−245640のステビア、甘草抽出物、ラカンカ抽出物を添加する方法などがあるが、これらの効果は十分でなく、添加した物質の風味が発泡性粉末飲料の風味に影響を与えるなどの問題がある。
【0007】
また、従来の発泡性粉末飲料は溶解性が悪いため、形成された泡の層の中に発泡性粉末飲料の塊が巻き上げられて静止するなどの問題がある。特願2001−189970にはこの問題を解決するために砂糖を高甘味度甘味料に置換し、造粒物のかさ密度を0.55以上に調整する方法が提案されているが、この方法では高甘味度甘味料の使用が必須になる。
【0008】
【発明が解決しようとする課題】
本発明は、上記問題点の解決を意図するものであり、溶解性にすぐれ、発泡性良好な発泡性粉末飲料を提供することを目的とする。
【0009】
【課題を解決するための手段】
本発明者は、上記課題を解決するために常温固形油脂に着目し、種々検討した結果、本発明に到達した。
【0010】
すなわち、上昇融点24℃〜40℃の常温固体油脂を用いて造粒することにより、溶解性にすぐれ、発泡性良好な発泡性粉末飲料を提供することが可能となった。上昇融点24℃〜40℃の常温固体油脂を用いて造粒することにより、発泡性粉末飲料の溶解性が向上し、形成された泡の層の中に発泡性粉末飲料の塊が巻き上げられて静止することがない。また、発泡性粉末飲料が速やかに溶解するために、炭酸塩と有機酸の反応が速やかに進行し、短時間に二酸化炭素が発生する。このことにより、液体上部に形成される泡の層の高さの最大値が大きくなる。さらに、常温固体油脂が形成された泡を保護するため、泡の持続性が向上する。さらにまた、造粒に水を使用することがないので、有機酸を含む部分と炭酸塩を含む部分を同時に造粒することができ、製造工程が単純になる。
【0011】
【発明の実施の形態】
以下、本発明を詳細に説明する。
【0012】
本明細書では、常温固体油脂とは常温で固体である油脂をいい、具体的には、20℃で24時間静置した際に固体である油脂をいう。また、同様に静置した際に液体である油脂を常温液体油脂という。常温固体油脂の原料は特に限定しないが、例として、ダイズ油、ナタネ油、コーン油、綿実油、米ぬか油、ヒマワリ油、アマニ油、オリーブ油、パーム油、パーム核油、カカオ脂などの植物油脂、牛脂、豚脂、魚油などの動物油脂が挙げられる。これらの原料は単体で用いてもよいし、複数混合して用いてもよい。また、これらの原料はそのまま用いてもよいし、精製、硬化、分別、脱臭など加工して用いてもよい。
【0013】

【0015】
▲2▼試料を調整した毛細管を、長さ385〜390mm、水銀球の長さ15〜25mm、1/5℃目盛りの温度計の下部に輪ゴムまたは適当な方法で密着させ、毛細管の下端と温度計の下端をそろえる。
【0016】

▲4▼ビーカーの水を攪拌しながら、最初は1分に2℃ずつ、融点の10℃下に達した後は1分に0.5℃ずつ上昇する様加熱し、試料が毛細管中で上昇し始める温度を上昇融点とする。
【0018】
本発明に用いる常温固体油脂の上昇融点が24℃未満の場合は、発泡性粉末飲料の流動性が低下し、ブロッキングを起こすなど取扱いが困難になる。また、常温固体油脂の上昇融点が40℃を越える場合は、発泡性粉末飲料の溶解性が悪くなり、風味が重くなる。
【0019】

【0021】
本明細書では、発泡性良好とは、発泡量が多く泡の持続性が高いことをいう。具体的には、内径65mm、高さ85mmのビーカー(容量200ml)を用い、所定量の発泡性粉末飲料に対し100mlの液体を加え溶解した際に、最大値で高さ15mm以上の泡の層を形成し、これが1分間以上持続することをいう。
【0022】
本発明において、造粒に用いる常温固体油脂の量は、発泡性が良好である限りにおいていくらでもよいが、常温固体油脂以外の原料100重量部に対して5重量部〜30重量部用いることが望ましい。常温固体油脂以外の原料100重量部に対して用いる常温固体油脂の量が5重量部未満の場合には、造粒が不十分となり、溶解性が不十分になるなどの問題が発生することがある。また、常温固体油脂以外の原料100重量部に対して用いる常温固体油脂の量が30重量部より多い場合には、油脂の風味が強くなり発泡性粉末飲料の風味のバランスを損なう、流動性が低下するなどの問題が発生することがある。
【0023】
本明細書では、攪拌造粒機とは、縦形の混合層の内部に底部より突き出した攪拌軸を持ち、この軸に攪拌羽根を取り付けて粉末の混合を行う造粒機をいう。攪拌軸を複数持つもの、混合層の外側にジャケットを有し、加熱、冷却が可能なものもある。攪拌造粒機の例としては、株式会社ダルトン製パワーニーダーPK−350、不二パウダル株式会社製SPG−2000、深江パウテック株式会社製LFS−GS−2J型ハイスピードミキサー、株式会社パウレック製VG−3000などが挙げられる。

本発明によれば、溶解性にすぐれ、発泡性良好な発泡性粉末飲料を提供することができる。[0001]
[Industrial application fields]
The present invention relates to an effervescent powder beverage that forms a cappuccino-like foam layer on top of the liquid when dissolved in the liquid.
[0002]
[Prior art]
In sparkling beverages such as cappuccino and latte, the amount and persistence of the foam layer formed on the top of the liquid is an important quality factor. In addition, when a powdered product of these sparkling beverages is dissolved in a liquid such as hot water and drunk, it is important that preparation is simple such as excellent solubility and easy foaming. Furthermore, in producing a sparkling powdered beverage, it is desirable that the process is simple.
[0003]
Conventionally proposed means for foaming of effervescent powder beverages are those by shaking, those by gas-containing effervescent creaming powder, and those by generating carbon dioxide by the reaction of carbonate and acid. There are JP-A-2000-270818, JP-A-2000-157232, and JP-A-10-295339 which are caused by shaking. However, these need to be shaken after filling in a container, and preparation for drinking is complicated. .
[0004]
Japanese Patent Application Laid-Open No. 11-503920 is known as a gas-containing foaming creaming powder. However, the gas-containing foaming creaming powder alone has a problem that the foaming amount is small and the sustainability of the foam is low.
[0005]
Japanese Patent Laid-Open No. 10-066531 discloses that carbon dioxide is generated by a reaction between an acid and a carbonate, but the manufacturing method is complicated. In the production of an effervescent powder beverage, granulation is generally performed in order to improve solubility, but carbonate and acid are dissolved and reacted in water in the binder. The reaction ends quickly and the finished product will not foam. In order to avoid this, it is necessary to granulate the acid-containing part and the carbonate-containing part separately. In addition, there is a problem that the persistence of bubbles is low only by generating carbon dioxide by the reaction between an acid and a carbonate.
[0006]
As a means for improving the persistence of foam in a conventionally proposed sparkling powder beverage, a method of adding a hop extract described in JP-A-9-163969, a stevia, a licorice extract, and a rakanka extract disclosed in JP-A-2001-245640 However, these effects are not sufficient, and there is a problem that the flavor of the added substance affects the flavor of the sparkling powder beverage.
[0007]
In addition, since the conventional sparkling powder beverage has poor solubility, there is a problem that a lump of the sparkling powder beverage is rolled up in the formed foam layer and becomes stationary. In order to solve this problem, Japanese Patent Application No. 2001-189970 proposes a method of replacing sugar with a high-intensity sweetener and adjusting the bulk density of the granulated product to 0.55 or more. The use of high-intensity sweeteners is essential.
[0008]
[Problems to be solved by the invention]
The present invention is intended to solve the above-described problems, and an object thereof is to provide an effervescent powder beverage having excellent solubility and good effervescence.
[0009]
[Means for Solving the Problems]
The inventor of the present invention has reached the present invention as a result of various investigations focusing on room temperature solid oils and fats in order to solve the above problems.
[0010]
That is, it became possible to provide an effervescent powdered beverage having excellent solubility and good foaming properties by granulating using a normal temperature solid oil having a rising melting point of 24 ° C to 40 ° C. By granulating with room temperature solid fats and oils having a rising melting point of 24 ° C to 40 ° C, the solubility of the effervescent powder beverage is improved, and the lump of the effervescent powder beverage is rolled up in the formed foam layer. There is no rest. In addition, since the sparkling powder beverage is rapidly dissolved, the reaction between the carbonate and the organic acid proceeds rapidly, and carbon dioxide is generated in a short time. This increases the maximum height of the foam layer formed above the liquid. Furthermore, since the foam in which normal temperature solid fats and oils are formed is protected, the sustainability of the foam is improved. Furthermore, since water is not used for granulation, a part containing an organic acid and a part containing a carbonate can be granulated at the same time, thereby simplifying the production process.
[0011]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described in detail.
[0012]
In this specification, normal temperature solid fats and oils refer to fats and oils that are solid at normal temperature, specifically, fats and oils that are solid when left at 20 ° C. for 24 hours. Similarly, fats and oils that are liquid when allowed to stand are referred to as room temperature liquid fats and oils. The raw materials for room temperature solid fats and oils are not particularly limited.For example, vegetable oils such as soybean oil, rapeseed oil, corn oil, cottonseed oil, rice bran oil, sunflower oil, linseed oil, olive oil, palm oil, palm kernel oil, cocoa butter, Examples include animal fats such as beef tallow, pork tallow, and fish oil. These raw materials may be used alone or in combination. Moreover, these raw materials may be used as they are, or may be used after processing such as purification, curing, fractionation, and deodorization.
[0013]
In the present specification, the rising melting point means a temperature at which a sample begins to flow when it is heated according to a prescribed method. The method for measuring the rising melting point is detailed in “Standard oil analysis test method” edited by Japan Oil Chemistry Association, but is outlined in (1) to (4) below.
[0014]
(1) The melted sample was viewed up to a height of 10 mm in a capillary tube having an inner diameter of 1 mm, an outer diameter of 2 mm or less, and a length of 50 to 80 mm and opened at both ends. put.
[0015]
(2) The capillary tube with the sample prepared is closely attached to the lower part of a thermometer having a length of 385 to 390 mm, a length of mercury bulb of 15 to 25 mm and a scale of 1/5 ° C. by a rubber band or an appropriate method, and the lower end of the capillary and the temperature. Align the bottom of the meter.
[0016]
(3) This thermometer is immersed in a beaker (content 600 ml) of a suitable size and filled with water, and the lower end of the thermometer is placed at a depth of about 30 mm below the surface of the water.
[0017]
(4) While stirring the water in the beaker, heat the sample so that the temperature rises by 2 ° C. per minute and then rises by 0.5 ° C. per minute after reaching the melting point of 10 ° C., and the sample rises in the capillary tube. The temperature at which heat treatment starts is defined as the rising melting point.
[0018]
When the rising melting point of the room-temperature solid fat used in the present invention is less than 24 ° C., the flowability of the sparkling powdered beverage is lowered and handling such as blocking becomes difficult. Moreover, when the rising melting | fusing point of normal temperature solid fats and oils exceeds 40 degreeC, the solubility of an effervescent powder drink will worsen and a flavor will become heavy.
[0019]
In this specification, granulation refers to an operation of making particles from powder, and more specifically, an operation of making particles having a substantially uniform shape and size from raw materials such as granules, lumps, solutions, or melts. Say. The boundary between the powder and the grain is about 100 μm, and the finer than 100 μm is called powder, and the larger than 100 μm is called grain. By granulating powder, fluidity is improved, scattering of fine powder can be prevented, segregation can be prevented, ventilation resistance is reduced, cohesion is reduced, liquid solubility is improved, density adjustment is possible There are advantages such that the appearance is beautiful, the weighing is simple when granulated into tablets and pellets. The granulation method is not particularly limited, but examples include stirring granulation method, rolling granulation method, fluidized bed granulation method, rolling fluidized bed granulation method, air flow granulation method, spray granulation method, extrusion granulation method.
