Description

【0001】
【発明が属する技術分野】
本発明は、物性に優れた可食性乳化剤造粒粉末及び該造粒粉末の製造法に関する。
【0002】
【従来の技術】
可食性乳化剤は食品においては幅広い用途に数多く使用されている。しかしながら、その粉末製剤においては物性がハンドリングに大きく影響するため、様々な粉末化方法が検討されてきている。可食性乳化剤粉末の製剤化方法に関しては、可食性乳化剤の希薄溶液を濃縮しながら乾燥する噴霧乾燥法(特許文献1、2など参照)がある。噴霧乾燥法は工程が簡単であるが、熱源費が大きい上に微粉となりやすく、粉末品の固結の原因となりやすい。また、可食性乳化剤の塊状体を衝撃剪断型粉砕機で粉砕しながら分級して可食性乳化剤粉末を製造する方法(特許文献3)があるが、可食性乳化剤の塊を作成するための前工程が必要で、嵩比重が軽く粉塵爆発の危険性や取り扱いにくいなど更なる検討が必要である。また、有機溶媒を含有する可食性乳化剤水溶液を凍結乾燥することにより、可食性乳化剤粉末を得る方法(特許文献4)があるが、同様に粉塵爆発の危険性、嵩比重の軽さなど、ハンドリングの問題がある。また、常温でペースト状または液状の乳化剤を粉末化し、取り扱い性、混和性、非固結性、保存安定性、溶解性および分散性に優れ、しかも乳化剤含量の多い粉末乳化剤を得る製造方法(特許文献5)があり、その中で可食性乳化剤の粉末化がなされているが、やはり嵩比重の軽さ、固結などという問題がある。また通常の粉末品は、溶解させる際にその嵩比重の軽さから溶媒表面に浮かびやすく、ミキサー処理を行うと泡立ちの原因となることが多い。特に、高いHLB(12〜15)を持つ可食性乳化剤においては上記問題点が顕著であり、物性の改善が求められていた。

【発明が解決しようとする課題】
したがって、本発明の目的は、物性の改善された可食性乳化剤造粒粉末の提供であり、詳しくは、高いHLBを持つ可食性乳化剤においても、ハンドリングが良く、水に溶解させる際ミキサー処理を行っても泡立ちが起こらず、かつ、固結の原因となる吸湿性が改善された可食性乳化剤の造粒粉末を提供することである。

(2)賦形剤と水と可食性乳化剤とエタノールからなる液体原料から連続的に直接、球形状顆粒を製造する噴霧乾燥式流動層造粒装置を用いて、流動層レイヤリング造粒法により得られる可食性乳化剤造粒粉末であって該粉末の嵩密度が0.5g/ml〜0.9g/mlであることを特徴とする可食性乳化剤造粒粉末

【0006】
【発明の実施の形態】
以下に、本発明を実施の形態に合わせて詳細に説明する。本発明においては、加熱した空気によって流動化させた核粒子の床の中に可食性乳化剤(好ましくはHLBが12〜15)含有溶液を噴霧し、流動層の温度を80℃〜140℃に保持する造粒方法、すなわち流動層レイヤリング造粒法が用いられる。本発明で用いられる造粒装置としては、流動層レイヤリング造粒法として確立された噴霧乾燥式流動層造粒装置であれば、その構造については特に限定されるものではないが、例えば、アグロマスタAGM−SD型(ホソカワミクロン社製)が挙げられる。この噴霧乾燥式流動層造粒装置では、従来における乾燥(噴霧乾燥又は真空乾燥)、液添(造粒用水分調整)、造粒(流動層又は押出造粒機)、球形化(転動球形化機)、仕上げ乾燥(流動乾燥機)を一つの装置(1プロセス)で実現できるので、効率的、かつ、経済的な造粒乾燥システムで可食性乳化剤粉末が得られることとなる。この装置の実際については、特開2001−86971号公報を参照することができる。
【0007】
本発明で用いられる可食性乳化剤は、可食性であれば特に限定されることはなく、例えばエンジュサポニン、オオムギ殻皮抽出物、キラヤ抽出物、グリセリン脂肪酸エステル、酵素処理大豆サポニン、酵素処理レシチン、植物性ステロール、植物レシチン、スフィンゴ脂質、ショ糖脂肪酸エステル、ステアロイル乳酸カルシウム、ソルビタン脂肪酸エステル、ダイズサポニン、胆汁末、チャ種子サポニン、動物性ステロール、トマト糖脂質、ビートサポニン、プロピレングリコール脂肪酸エステル、分別レシチン、ユッカフォーム抽出物、卵黄レシチンなどの乳化剤の他、アラビアガム、カードラン、カラギーナン、CMC、ローカストビーンガム、キサンタンガム、キダチアロエ抽出物、キチン、キトサン、グァーガム、グルコサミン、酵母細胞壁、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、タラガム、ダンマル樹脂、デキストラン、トラガントガム、微小繊維状セルロース、プルラン、ペクチン、メチルセルロース、モモ樹脂、ラムザンガム、レバン、ポリオキシエチレン硬化ひまし油、ポリオキシエチレンアルキルエーテル、ポリオキシエチレンポリオキシプロピレン共重合体、ポリグリセリン脂肪酸エステル、ポリオキシエチレンソルビタン脂肪酸エステル、ポリオキシエチレンソルビット脂肪酸エステル、ポリオキシエチレングリセリン脂肪酸エステル、ポリオキシエチレングリコール脂肪酸エステル、ポリオキシエチレンアルキルエーテルリン酸及びその塩、ポリオキシエチレンアルキルエーテル硫酸塩、ポリオキシエチレンフィトステロール及びフィトスタノール、ポリオキシエチレンアルキルフェニルエーテルリン酸及びその塩、ポリオキシエチレンラノリン及びラノリンアルコール、ポリオキシエチレンアルキルアミン及び脂肪酸アミド、ポリオキシエチレンアルキルフェニルホルムアルデヒド縮合物、ポリオキシエチレンポリオキシプロピレンアルキルエーテル、ポリオキシエチレンアルキルフェニルエーテル及び脂肪酸エタノールアミド等が挙げられる。しかしながら、本発明の課題は、可食性乳化剤のHLBが12〜15の場合に顕著であり、したがって本発明の効果もHLBが12〜15の可食性乳化剤において特に有効である。そのようなHLBを示す可食性乳化剤としては、ショ糖脂肪酸エステルが特に好ましく用いられる。そして、その全エステル体に占めるモノエステル体の含有量が50重量%以上であり、特に好ましくは70重量%以上であり、最も好ましくは90重量%以上であり、また、構成脂肪酸においても、パルミチン酸が60%モル以上であるものが最も好ましい。そのような可食性乳化剤としては、例えばモノエステルPの商品名(三菱化学フーズ(株)製、凍結乾燥品)で一般に入手することができる。
【0008】
本発明において流動層レイヤリング造粒法により得られる造粒粉末は重質であり、通常は嵩密度0.5g/ml〜0.9g/mlであり、好ましくは0.7g/ml〜0.9g/mlで用いることができる。嵩密度が0.5g/ml未満であれば、吸湿性が現れることがあり、軽質でハンドリング性に欠けることがある。嵩密度が0.9g/mlを越えたときは、かえって流動性に問題が生じることがある。本発明における嵩密度の測定は、ABD−粉体特性測定器(筒井理化学会社製)にて行うことができる。
【0009】
本発明における可食性乳化剤造粒粉末の平均粒子径は、特に限定されるものではないが、好ましくは50μm〜500μm、更に好ましくは100μm〜500μmとすることが望ましい。平均粒子径が50μm未満であれば、流動性が悪くなる傾向があり、平均粒子径が500μmを越えたときは本発明の効果が十分発揮されないことがある。本発明における平均粒子径は、JIS規格篩を使用した篩分法に基づいて測定できる。本発明の可食性乳化剤造粒粉末は、嵩密度が0.5g/ml〜0.9g/mlで、かつ、平均粒子径が50μm〜500μmであるときに最も効果的である。そのような嵩密度と平均粒子径の調整は、流動層の温度、送風量、噴霧溶液の流量、噴霧空気の流量と圧力などの調整により行うことができる。
【0010】
本発明においては、液体原料にエタノールを含有せしめることも有用である。このエタノールは、可食性乳化剤の水への溶解を補助し、均一な液体原料を調製するのに役立ち、本発明の可食性乳化剤造粒粉末の品質向上に資するものである。そのようなエタノールの添加量としては、好ましくは可食性乳化剤に対して重量比で0.1〜5倍量、更に好ましくは0.2〜2倍量、特に好ましくは0.5〜1倍量で用いることができる。
【0011】
本発明で用いられる液体原料には、賦形剤を用いることも好ましい態様である。そのような賦形剤としては、例えば、グルコース、フラクトース、ガラクトースなどの単糖類、ショ糖、マルトースなどの二糖類、澱粉を液化し得られる澱粉部分分解物などが例示され、これらは単独で又は2種以上を組み合わせて使用することができるが、澱粉分解物が特に好ましく用いられる。
【0013】
本発明で用いられる粉末製造装置は「流動層レイヤリング造粒原理」であるため従来の製造プロセスで顆粒化のために行っていた「再液添加操作」や「仕上げ乾燥操作」が不要である特徴も兼ね備えている。
【0014】
本発明の好ましい一態様を挙げれば、例えばHLBが12〜15である可食性乳化剤0.1〜60重量部を95%エチルアルコール25重量部に60℃付近で加温溶解させ、次いで水225〜325重量部を添加し均一に撹拌した後、デキストリン(DE:10)40〜99.9重量部を水50重量部に溶解させた溶液と混合し、得られた溶液をアグロマスタAGM−SD型(ホソカワミクロン社製)を用い送風温度130℃で噴霧乾燥およびコーティング造粒(レイヤリング造粒)を行った後、篩がけにより粒子径150〜500μmの流動性に優れた可食性乳化剤造粒粉末(可食性乳化剤0.1〜60%含有)を得る事ができる。

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described in detail according to embodiments. In the present invention, a solution containing an edible emulsifier (preferably HLB of 12 to 15) is sprayed into a bed of core particles fluidized by heated air, and the temperature of the fluidized bed is maintained at 80 to 140 ° C. The granulation method to be used, that is, the fluidized bed layering granulation method is used. The granulator used in the present invention is not particularly limited as long as it is a spray-drying fluid bed granulator established as a fluid bed layering granulation method. AGM-SD type (manufactured by Hosokawa Micron Corporation) can be mentioned. In this spray drying fluidized bed granulator, conventional drying (spray drying or vacuum drying), liquid addition (moisture adjustment for granulation), granulation (fluidized bed or extrusion granulator), spheronization (rolling sphere) ) And finish drying (fluid dryer) can be realized by one apparatus (one process), so that an edible emulsifier powder can be obtained by an efficient and economical granulation drying system. Japanese Patent Laid-Open No. 2001-86971 can be referred to for the actual device.
[0007]
The edible emulsifier used in the present invention is not particularly limited as long as it is edible. For example, Enjusaponin, barley husk extract, quilla extract, glycerin fatty acid ester, enzyme-treated soybean saponin, enzyme-treated lecithin, Plant sterol, plant lecithin, sphingolipid, sucrose fatty acid ester, stearoyl calcium lactate, sorbitan fatty acid ester, soybean saponin, bile powder, tea seed saponin, animal sterol, tomato glycolipid, beet saponin, propylene glycol fatty acid ester, fractionation In addition to emulsifiers such as lecithin, yucca foam extract, egg yolk lecithin, gum arabic, curdlan, carrageenan, CMC, locust bean gum, xanthan gum, extract of chidachi aloe, chitin, chitosan, guar gum, glucosamine, fermentation Cell wall, psyllium seed gum, gellan gum, tamarind seed gum, tara gum, dammar resin, dextran, tragacanth gum, microfibrous cellulose, pullulan, pectin, methylcellulose, peach resin, ramzan gum, levan, polyoxyethylene hydrogenated castor oil, polyoxyethylene alkyl ether , Polyoxyethylene polyoxypropylene copolymer, polyglycerin fatty acid ester, polyoxyethylene sorbitan fatty acid ester, polyoxyethylene sorbit fatty acid ester, polyoxyethylene glycerin fatty acid ester, polyoxyethylene glycol fatty acid ester, polyoxyethylene alkyl ether phosphorus Acids and salts thereof, polyoxyethylene alkyl ether sulfates, polyoxyethylene phytosterols and Phytostanol, polyoxyethylene alkylphenyl ether phosphoric acid and salts thereof, polyoxyethylene lanolin and lanolin alcohol, polyoxyethylene alkylamine and fatty acid amide, polyoxyethylene alkylphenyl formaldehyde condensate, polyoxyethylene polyoxypropylene alkyl ether, Examples include polyoxyethylene alkylphenyl ether and fatty acid ethanolamide. However, the problem of the present invention is remarkable when the edible emulsifier has an HLB of 12 to 15. Therefore, the effect of the present invention is also particularly effective in an edible emulsifier with an HLB of 12 to 15. As an edible emulsifier exhibiting such HLB, sucrose fatty acid esters are particularly preferably used. The content of the monoester in the total ester is 50% by weight or more, particularly preferably 70% by weight or more, and most preferably 90% by weight or more. The acid is most preferably 60% mol or more. Such an edible emulsifier can be generally obtained, for example, under the trade name of Monoester P (manufactured by Mitsubishi Chemical Foods Co., Ltd., freeze-dried product).
[0008]
The granulated powder obtained by the fluidized bed layering granulation method in the present invention is heavy, and usually has a bulk density of 0.5 g / ml to 0.9 g / ml, preferably 0.7 g / ml to 0.00. It can be used at 9 g / ml. If the bulk density is less than 0.5 g / ml, hygroscopicity may appear, and it may be light and lack handling properties. When the bulk density exceeds 0.9 g / ml, there may be a problem with fluidity. The measurement of the bulk density in the present invention can be performed with an ABD-powder characteristic measuring instrument (manufactured by Tsutsui Chemical Co., Ltd.).
[0009]
The average particle diameter of the edible emulsifying agent granulated powder in the present invention is not particularly limited, preferably 50 microns and 500 microns, more preferably it is desirable that the 100Myuemu~500myuemu. If the average particle size is less than 50 μm, the fluidity tends to be poor, and if the average particle size exceeds 500 μm, the effects of the present invention may not be sufficiently exhibited. The average particle diameter in the present invention can be measured based on a sieving method using a JIS standard sieve. Edible emulsifying agent granulated powder of the present invention had a volume density of 0.5g / ml~0.9g / ml, and is most effective when the average particle diameter of 50 microns and 500 microns. Such bulk density and average particle diameter can be adjusted by adjusting the temperature of the fluidized bed, the air flow rate, the flow rate of the spray solution, the flow rate and pressure of the spray air, and the like.
[0010]
In the present invention, it is also useful to include ethanol in the liquid raw material. The ethanol assists dissolution in water edible emulsifier helps to prepare a homogeneous liquid material, it is to contribute to improving the quality of edible emulsifying agent granulated powder of the present invention. The amount of such ethanol added is preferably 0.1 to 5 times by weight, more preferably 0.2 to 2 times, particularly preferably 0.5 to 1 times the weight of the edible emulsifier. Can be used.
[0011]
