Description

【0001】
【発明の属する技術分野】
本発明は、水、牛乳、豆乳等の液体、特に水に易溶性の粉末状或いは顆粒状食品に関し、さらに詳しくはトリグリセリンベヘン酸エステルを含有することを特徴とする粉末状或いは顆粒状の食品及びその製造法に関する。
【0002】
【従来の技術】
粉末スープや粉末ソース類、或いはココア粉末等の粉末食品は、調理や飲食の際、水に溶解させようとしたとき、水濡れが悪く、容易に分散又は溶解せず、集積してままこ(ダマ)になる。そのためこれら粉末食品を分散又は溶解するには、予め少量の水または湯で練った後、かき混ぜながら水又は湯を注ぎ込まなければならないという不便さがあった。
【0003】
この問題を解決するため、一般に粉末を顆粒化することが行われている。しかし、粉末食品の種類によっては、顆粒化の難しいもの、或いは顆粒化しても分散性又は溶解性が改善されないものもあり、根本的な解決方法とはなっていない。
【0004】
もう一つの有力な方法として、食品用乳化剤を用いることが行われている。即ち、流動層造粒乾燥機を用いて流動させた粉末状食品に乳化剤溶液を噴霧し、造粒する方法(例えば、特許文献1,2参照)、撹拌式造粒機或いは混合機を用いて粉末原料に乳化剤を加え混合後、得られた粉末或いは顆粒を乾燥する方法(例えば、特許文献3,4参照)、或いは粉末状或いは顆粒状の食品と粉末状或いは微粉末状の乳化剤を紛体混合する方法(例えば、特許文献5,6参照)等が提示されている。
しかし、これまでに示されたいずれの方法をもってしても、その効果はなお十分ではなかった。

【発明が解決しようとする課題】
本発明は、従来方法の欠点を克服し、水、温水或いは熱湯に分散又は溶解する際、「ままこ(ダマ)」を生じにくい、粉末状或いは顆粒状の食品を提供することを目的とする。
【0007】
【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鋭意研究を重ねた結果、粉末状或いは顆粒状の食品にトリグリセリンベヘン酸エステルを含有させることにより上記課題が解決されることを見出し、この知見に基づいて本発明を完成した。
すなわち、本発明は、次の1〜6からなっている。
1. トリグリセリンベヘン酸エステルを含有することを特徴とする、粉末状或いは顆粒状の食品。

5. 粉末状或いは顆粒状の食品にトリグリセリンベヘン酸エステルを含有させることを特徴とするトリグリセリンベヘン酸エステル含有粉末状或いは顆粒状の食品の製造方法。
6. トリグリセリンベヘン酸エステルの含有量が、0.01〜5質量%であることを特徴とする前記5に記載のトリグリセリンベヘン酸エステル含有粉末状或いは顆粒状の食品の製造方法。
【0008】
【発明の実施の形態】
本発明において用いられるトリグリセリンベヘン酸エステルは、トリグリセリンとベヘン酸とのエステル化生成物であり、エステル化反応等公知の手段で製造することができる。なお、本発明において、トリグリセリンベヘン酸エステルは、単品のみならず、トリグリセリンベヘン酸エステルを主成分とする混合組成物の形態でも使用することができる。
【0009】
ここで、トリグリセリンとしては平均重合度が約2.5〜3.4のポリグリセリン組成物、或いはグリセリン3分子からなるトリグリセリン、好ましくは直鎖状のトリグリセリン、の含有量が約50質量%以上、好ましくは約65質量%以上、より好ましくは約80質量%以上であるポリグリセリン組成物が挙げられる。
【0010】
該ポリグリセリン組成物は、通常、グリセリンもしくはグリシドール或いはエピクロルヒドリン等をそれ自体公知の方法で加熱し、重縮合反応させて得られる重合度の異なるポリグリセリンの混合物であり、好ましくはグリセリン及びジグリセリンを分離することにより、更に好ましくはトリグリセリン画分を分取することにより、トリグリセリンの含有量を高めたものである。トリグリセリンを高濃度化するための精製法としては、蒸留及び/又はカラムクロマトグラフィー等公知の方法を用いることができる。
【0011】
また、ベヘン酸としては、ベヘン酸の含有量が約50質量%以上、好ましくは約65質量%以上、更に好ましくは約80質量%以上の、脂肪酸或いは二種以上の脂肪酸との混合物が挙げられる。ここでベヘン酸以外の脂肪酸は、炭素数18以上の飽和脂肪酸、例えばステアリン酸が主たる脂肪酸であることが好ましい。
【0012】
更に、上記トリグリセリンベヘン酸エステルのエステル化率は、約40%以上、好ましくは約60%以上、更に好ましくは約80%以上である。エステル化率はトリグリセリンとベヘン酸の仕込み量でおおむね決まるが、正確にはエステル化生成物を分析することにより求めることができる。
ここでエステル化率は次のように定義される。
エステル化率 = エステル価 ÷(エステル価 + 水酸基価)×100
※エステル価 = けん化価 − 酸価
【0013】
本発明は、好ましくは、トリグリセリンベヘン酸エステルを含有していない粉末状或いは顆粒状の食品或いはその仕掛り品に、トリグリセリンベヘン酸エステルを含有させることにより行われる。尚、本発明で言う食品には、このような粉末状或いは顆粒状の食品或いはその仕掛り品の原料として使用される、食品素材加工品或いは食品添加物も含まれる。

【0014】
このような食品としては、例えば即席コーンポタージュスープ、即席クリームスープ、即席カレースープ、即席中華麺スープ、即席味噌汁等の即席スープ類;即席カレー粉類;即席クリームシチュー、即席ビーフシチュー、即席ブラウンシチュー等のシチュー類;粉末焼きそばソース、粉末うどんつゆ、粉末醤油、粉末酢、粉末味噌等の粉末調味料類;インスタントコーヒー、インスタントココア、粉末緑茶、粉末ミルクセーキ等の粉末飲料類;インスタント・クリーミング・パウダー;即席デザートミツクス、粉末グラタンミックス、アイスクリームミックス等のミックス類が挙げられる。
【0015】
また、このような食品素材加工品としては、例えば小麦粉、上新粉、白玉粉、そば粉、とうもろこし粉のように穀類を粉砕し、粉末化したもの;とうもろこし澱粉、じゃがいも澱粉等の澱粉類;ブドウ糖、果糖等の単糖類;ショ糖、乳糖、麦芽糖等のオリゴ糖類;デキストリン、粉末水飴等の澱粉加水分解物;粉末肉エキス、粉末野菜エキス等のエキス類;畜類、魚類等の動物性および植物性蛋白質の加水分解物;全粉乳、脂肪粉乳、脱脂粉乳;マッシュポテト、野菜ペースト粉末;ハーブ、スパイス等の香辛料類が挙げられる。
【0016】
また、このような食品添加物としては、例えばアラビアガム、アルギン酸及び/又はその塩、カシアガム、ガティガム、カラギナン、カラヤガム、キサンタンガム、キチン、キトサン、グアーガム、サイリウムシードガム、ジェランガム、タマリンドシードガム、デキストラン、トラガントガム、ファーセレラン、プルラン、ペクチン等の増粘安定剤;ポリグリセリン脂肪酸エステル等の乳化剤;アスパルテーム、グリチルリチン酸二ナトリウム、ステビア抽出物等の甘味料;D−ソルビトール、D−マンニトール等の糖アルコール類など多種多様の食品添加物が挙げられる。
【0017】
粉末状或いは顆粒状の食品に添加され或いは混ぜられるトリグリセリンベヘン酸エステルは、平均粒子径が約250μm以下の粉末或いは顆粒であり、好ましくは平均粒子径が約75μm以下の微粉末、更に好ましくは平均粒子径が約10μm以下の微粒子である。該エステルの平均粒子径が小さくなるほど、それが添加され或いは混ぜられた粉末状或いは顆粒状の食品の分散性又は溶解性が良くなるが、一方、静電気を持つことにより取り扱いに不便を生じることから、目的・用途に応じて適宜粒度を選択することが好ましい。
【0018】
トリグリセリンベヘン酸エステルを粉末或いは顆粒化するための製法としては、特に制限はないが、通常、トリグリセリンベヘン酸エステルを融点以上に溶融後、スプレークーリングする等公知の方法が用いられる。また、これら粉末或いは顆粒を更に微粒子化するための方法としては、気相ジェットミル等公知の微粒子製造装置が用いられる。
【0019】
トリグリセリンベヘン酸エステルを粉末状或いは顆粒状の食品に含有させる方法としては特に制限はなく、例えば、
1)粉末・顆粒或いは微粒子状のトリグリセリンベヘン酸エステルと、前記粉末状或いは顆粒状の食品とを紛体混合する方法、
2)粉末・顆粒或いは微粒子状のトリグリセリンベヘン酸エステルを水或いは食用油脂に分散或いは溶解させた液を前記粉末状或いは顆粒状の食品に噴霧し、コーティング或いは造粒する方法、

などが挙げられる。
【0020】
本発明になるトリグリセリンベヘン酸エステルを含む粉末状或いは顆粒状食品中のトリグリセリンベヘン酸エステルの添加或いは混合量は、食品に対して通常約0.01〜5質量%、好ましくは約0.05〜3質量%、より好ましくは約0.1〜1質量%が適当である。添加或いは混合量が約0.01質量%未満の場合には、粉末の溶解性を改善する効果が不十分であり、また、約5質量%を越えると、風味が悪くなるので、食品として好ましくない。
【0021】
本発明の粉末状或いは顆粒状食品中には、本発明の目的を阻害しない範囲で、トリグリセリンベヘン酸エステルと共に、グリセリン脂肪酸エステル、ショ糖脂肪酸エステル、ソルビタン脂肪酸エステル、プロピレングリコール脂肪酸エステル、レシチン等の食品用乳化剤を加えることができる。ここで、グリセリン脂肪酸エステルには、グリセリンと脂肪酸のエステルの外、グリセリン酢酸エステル、グリセリン酢酸脂肪酸エステル、グリセリン乳酸脂肪酸エステル、グリセリンクエン酸脂肪酸エステル、グリセリンコハク酸脂肪酸エステル、グリセリンジアセチル酒石酸脂肪酸エステル、ポリグリセリン脂肪酸エステル及びポリグリセリン縮合リシノール酸エステル等の1又は2以上が含まれる。またレシチンには、分別レシチン、酵素分解レシチン、酵素処理レシチン等が含まれてよい。

【発明の効果】
本発明によれば、従来方法に比べて液体、特に水、温水あるいは熱湯により易溶性の粉末状或いは顆粒状の食品が得られ、加えて粉末天然調味料のように、吸湿しやすく又固結しやすい食品においては固結防止の効果も期待できる。[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a powdery or granular food that is readily soluble in liquids such as water, milk, and soymilk, in particular water, and more particularly, a powdery or granular food containing triglycerin behenate. And its manufacturing method.
[0002]
[Prior art]
Powdered foods such as powdered soups, powdered sauces, or cocoa powder are poorly wet when they are dissolved in water during cooking, eating and drinking, do not easily disperse or dissolve, and remain accumulated ( Dama). Therefore, in order to disperse or dissolve these powdered foods, there has been an inconvenience that water or hot water must be poured while being stirred after kneading with a small amount of water or hot water.
[0003]
In order to solve this problem, the powder is generally granulated. However, some types of powdered foods are difficult to granulate, or some do not improve dispersibility or solubility even when granulated, which is not a fundamental solution.
[0004]
Another effective method is to use a food emulsifier. That is, an emulsifier solution is sprayed on a powdered food that has been fluidized using a fluidized bed granulator / dryer, and granulated (for example, see Patent Documents 1 and 2), a stirring granulator or a mixer. After adding emulsifier to powder raw material and mixing, the obtained powder or granule is dried (for example, see Patent Documents 3 and 4), or powdered or granulated food and powdered or finely powdered emulsifier are mixed in powder (For example, refer to Patent Documents 5 and 6) and the like.
However, even with any of the methods shown so far, the effect is still not sufficient.

[Problems to be solved by the invention]
An object of the present invention is to overcome the disadvantages of the conventional methods and to provide a powdered or granular food that is less likely to cause “dama” when dispersed or dissolved in water, hot water or hot water. .
[0007]
[Means for Solving the Problems]
As a result of intensive studies to solve the above problems, the present inventors have found that the above problems can be solved by adding triglycerin behenate to a powdered or granular food. Based on this, the present invention has been completed.
That is, this invention consists of the following 1-6.
1. A powdered or granular food comprising triglycerin behenate.
2. 2. The powdered or granular food according to 1 above, wherein the esterification rate of triglycerin behenate is 40% or more.
3. 2. The powdered or granular food according to 1 above, wherein the triglycerin behenate has an average particle size of 250 μm or less.
4). 2. The powdered or granular food according to 1 above, wherein the triglycerin behenate has an average particle size of 10 μm or less.
5. A method for producing a triglycerin behenate-containing powdered or granular food, characterized in that triglycerine behenate is contained in a powdered or granular food.
6). 6. The method for producing a triglycerin behenate-containing powdered or granular food according to 5 above, wherein the content of triglycerin behenate is 0.01 to 5% by mass.
[0008]
DETAILED DESCRIPTION OF THE INVENTION
The triglycerin behenic acid ester used in the present invention is an esterification product of triglycerin and behenic acid, and can be produced by a known means such as an esterification reaction. In the present invention, the triglycerine behenate can be used not only as a single product but also in the form of a mixed composition mainly composed of triglycerin behenate.
[0009]
Here, as triglycerin, the content of polyglycerin composition having an average degree of polymerization of about 2.5 to 3.4, or triglycerin composed of three molecules of glycerin, preferably linear triglycerin is about 50 mass. % Or more, preferably about 65% by mass or more, more preferably about 80% by mass or more.
[0010]
The polyglycerin composition is usually a mixture of polyglycerin having different degrees of polymerization obtained by heating glycerin, glycidol, epichlorohydrin or the like by a method known per se and performing a polycondensation reaction, preferably glycerin and diglycerin. More preferably, the triglycerin fraction is fractionated to increase the triglycerin content. As a purification method for increasing the concentration of triglycerin, known methods such as distillation and / or column chromatography can be used.
[0011]
Examples of behenic acid include fatty acid or a mixture of two or more fatty acids having a behenic acid content of about 50% by mass or more, preferably about 65% by mass or more, and more preferably about 80% by mass or more. . Here, the fatty acid other than behenic acid is preferably a saturated fatty acid having 18 or more carbon atoms, such as stearic acid.
[0012]
Furthermore, the esterification rate of the triglycerin behenate is about 40% or more, preferably about 60% or more, and more preferably about 80% or more. The esterification rate is largely determined by the amounts of triglycerin and behenic acid charged, but can be accurately determined by analyzing the esterification product.
Here, the esterification rate is defined as follows.
