Description

本発明は、遊離のキサントフィルと卵黄リン脂質とを含有し、水に分散可能な粉末状組成物およびその製造方法、ならびにこの粉末状組成物を含有する食品組成物に関する。   The present invention relates to a powdery composition containing free xanthophyll and egg yolk phospholipid and dispersible in water, a method for producing the same, and a food composition containing this powdery composition.

キサントフィルはカロテノイドの1種に分類され、自然界に色素として広く存在する。代表的なキサントフィルとしてルテイン、ゼアキサンチンが挙げられる。これらルテインやゼアキサンチンの生理効果として強力な抗酸化作用を有することが知られている。またルテイン、ゼアキサンチンは人体では眼の黄班部に存在し、これらが減少する事で視力低下や眼の病気を惹起することが知られている。そこで眼の健康を目的としたルテインを主成分とした健康食品が市販されている。しかし、ルテイン、ゼアキサンチンは水等極性溶媒にはほとんど溶解しないため、油脂に分散、溶解させソフトカプセルの形態でサプリメントとして販売されているのが現状である。そこで、多様な食品に容易に配合できるよう、水分散性が容易な剤形のルテイン含有組成物が望まれる。特許公報1(特開平10−1616号公報)にはカロテノイドまたはレチノールを高温下、揮発性の水混和性有機溶剤に溶解し、乳化剤存在下水性媒体を混合し懸濁液を調製する方法が開示されている。しかしここで実施例にて開示されている技術は、β‐カロテンを220℃に加熱されたイソプロピルアルコールに混和し、190℃の高温で分子状溶液を調製するものである。しかし、本製造方法には特殊な高温短時間熱処理可能な熱交換器を要し、カロテノイドの中でもキサントフィル類は上記方法では安定かつ均質な懸濁化は困難であるため、同出願人はキサントフィル類を安定な水分散液もしくは水分散性の乾燥粉末を得る方法として、分子量の異なる2種以上の保護コロイド成分を含む方法を特許文献2(特表2001−506685号公報)にて開示している。しかし、特殊なたん白加水分解物等を複数種類使用する必要があり、さらに簡単な組成で構成されたキサントフィル類、特にルテインやゼアキサンチンの懸濁液またはその乾燥粉末が要望される。   Xanthophylls are classified as one type of carotenoid and are widely present as pigments in nature. Typical xanthophylls include lutein and zeaxanthin. As a physiological effect of these lutein and zeaxanthin, it is known to have a strong antioxidant action. In addition, lutein and zeaxanthin are present in the macular area of the eye in the human body, and it is known that reduction of these causes visual loss and eye diseases. Therefore, health foods based on lutein for the purpose of eye health are commercially available. However, since lutein and zeaxanthin are hardly dissolved in polar solvents such as water, they are currently sold as supplements in the form of soft capsules after being dispersed and dissolved in fats and oils. Therefore, a lutein-containing composition having a dosage form with easy water dispersibility is desired so that it can be easily blended into various foods. Japanese Patent Laid-Open No. 10-1616 discloses a method of preparing a suspension by dissolving a carotenoid or retinol in a volatile water-miscible organic solvent at a high temperature and mixing an aqueous medium in the presence of an emulsifier. Has been. However, the technique disclosed in the examples here is to mix β-carotene with isopropyl alcohol heated to 220 ° C. to prepare a molecular solution at a high temperature of 190 ° C. However, this production method requires a special heat exchanger that can be heat-treated for a short time, and among the carotenoids, xanthophylls are difficult to be stably and homogeneously suspended by the above method. As a method for obtaining a stable aqueous dispersion or water-dispersible dry powder, a method comprising two or more kinds of protective colloid components having different molecular weights is disclosed in Japanese Patent Application Laid-Open No. 2001-506665. . However, it is necessary to use a plurality of special protein hydrolysates and the like, and there is a demand for xanthophylls, particularly lutein and zeaxanthin suspensions or dry powders having a simple composition.

ルテイン等キサントフィルは有用な健康機能素材である。本発明により、キサントフィル類を多様な食品形態に加工し、手軽に消費者に提供できるようになるため、キサントフィルの新たな需要を拡大することができる。   Xanthophylls such as lutein are useful health functional materials. According to the present invention, since xanthophylls can be processed into various food forms and can be easily provided to consumers, new demand for xanthophyll can be expanded.

以下、本発明の粉末状食品組成物を詳述する。なお、本発明において「%」は「質量%」を、「部」は「質量部」を意味する。   Hereinafter, the powdered food composition of the present invention will be described in detail. In the present invention, “%” means “mass%” and “part” means “part by mass”.

本発明の粉末状組成物は、有効成分としてルテイン、ゼアキサンチンに代表されるキサントフィルを遊離の形で含み、分散安定性を付与するため卵黄リン脂質が配合された、水分散性に優れた粉末状組成物である。本発明品である粉末状組成物は、水や水系媒体に容易に分散し、適切な濃度や環境下においては優れた安定性を示す。従ってキサントフィルの生理効果を期待する健康機能訴求の食品素材として有用である。またこの粉末状組成物は、このまま粉末状で、または水等に分散し、懸濁液の状態で容易に一般食品に配合することができる。
本発明の粉末状組成物の製造方法として、キサントフィル分散液を調製し、これを脱水することができる。本発明によると、比較的高濃度の分散液を調製することが可能であるため、脱水し容易に粉末状組成物を得ることができる。また、脱水する前の分散液を一般食品に配合することも、食品加工上可能である。
The powdered composition of the present invention contains xanthophyll as represented by lutein and zeaxanthin as active ingredients in a free form, and is blended with egg yolk phospholipid to impart dispersion stability, and is in a powdery form with excellent water dispersibility It is a composition. The powdery composition which is the product of the present invention is easily dispersed in water or an aqueous medium and exhibits excellent stability under an appropriate concentration and environment. Therefore, it is useful as a food material for health function promotion that expects the physiological effect of xanthophyll. Moreover, this powdery composition is in powder form as it is, or is dispersed in water or the like, and can be easily blended into general foods in the form of a suspension.
As a method for producing the powdery composition of the present invention, a xanthophyll dispersion can be prepared and dehydrated. According to the present invention, since it is possible to prepare a dispersion having a relatively high concentration, a powdery composition can be easily obtained by dehydration. It is also possible for food processing to mix the dispersion before dehydration into general foods.

本発明品の有効成分であるキサントフィルとしては、例えば、ルテイン、ゼアキサンチン、アスタキサンチン、カンタキサンチン、イソゼアキサンチン、3’−ヒドロキシエキネノン、4’−ヒドロキシエキネノン、フェニコキサンチン、2−ヒドロキシカンタキサンチン、イドキサンチン、クラスタキサンチン、アドニキサンチン、アンテラキサンチン、ビキシン、カプサンチン、カプソルビン、クロセチン、β−アポ−8’−カロテナール、エチル−β−アポ−8’−カロテノイン酸、フコキサンチン、ビオラキサンチンが挙げられ、このうち、ルテインまたはゼアキサンチン、もしくはこの両方であることが好ましい。   Examples of the xanthophyll that is an active ingredient of the product of the present invention include, for example, lutein, zeaxanthin, astaxanthin, canthaxanthin, isozeaxanthin, 3′-hydroxyechinenone, 4′-hydroxyechinenone, phenicoxanthine, 2-hydroxycanthane. Xanthine, idoxanthin, cluster xanthine, adonixanthin, anthaxanthin, bixin, capsanthin, capsorubin, crocetin, β-apo-8′-carotenal, ethyl-β-apo-8′-carotenoic acid, fucoxanthin, violaxanthin Of these, lutein and zeaxanthin, or both are preferred.

通例、天然由来のキサントフィルは、脂肪酸がエステル結合したエステル体で存在する。しかし、本発明の水に分散可能な粉末状組成物を得るためには、キサントフィルは遊離体である必要がある。つまり、天然由来のエステル体を脱アシル化したものである必要がある。後に試験例で述べるが、エステル体は卵黄リン脂質と併用しても容易に揮発性有機溶媒に溶解することができない。従って適切な濃度の懸濁液を調製することが困難であるため、粉末状組成物を得られにくい。従って、キサントフィルは遊離体である必要がある。また、キサントフィルの含量は、粉末組成物100gに対し、500〜3000mgが好ましく、500〜2000mgがさらに好ましい。これ以上少ないと、食品素材として用いる際、キサントフィルの生理効果を出すために粉末状組成物を過量に配合する必要がある。これより多いと、水に分散させた際、安定性が保てず沈殿が発生する場合がある。   Usually, naturally occurring xanthophyll exists in an ester form in which fatty acids are ester-bonded. However, in order to obtain the powdery composition dispersible in water of the present invention, xanthophyll needs to be free. In other words, it is necessary to deacylate a naturally derived ester. As will be described later in Test Examples, the ester cannot be easily dissolved in a volatile organic solvent even when used in combination with egg yolk phospholipid. Therefore, since it is difficult to prepare a suspension having an appropriate concentration, it is difficult to obtain a powdery composition. Therefore, xanthophyll needs to be free. Moreover, 500-3000 mg is preferable with respect to 100 g of powder compositions, and, as for the content of xanthophyll, 500-2000 mg is more preferable. If it is less than this, when used as a food material, it is necessary to add an excessive amount of the powdery composition in order to exert the physiological effect of xanthophyll. When it is more than this, stability may not be maintained and dispersion may occur when dispersed in water.

本発明品に用いる卵黄リン脂質とは、卵黄の構成脂質であるホスファチジルコリン、ホスファチジルエタノールアミン、スフィンゴミエリン、およびこれらのリゾ体の総称であり、これらを主成分とする脂質組成物をいう。卵黄リン脂質中のリン脂質含量は精製度合いにもよるが、本発明に用いる場合、60%以上が好ましく、80%以上がより好ましい。卵黄リン脂質中のリン脂質組成は、原料である卵黄に由来するが、精製により特定のリン脂質やコレステロール等他の脂質成分を除去することにより、リン脂質含量を高めことができる。ホスフォリパーゼA等を卵黄リン脂質に作用させることにより、一部又は全部をリゾ化することができる。リゾ化率、つまりリン脂質全質量に対するリゾリン脂質の質量百分率は、ホスフォリパーゼA処理条件、例えば酵素の種類、量、処理時間、温度により調整することができる。また、別途高度にリゾ化したリン脂質を、未処理リン脂質に特定の比率で均一に混和することで、適宜リゾ化率を調整することもできる。本発明では一部リゾ化した卵黄リン脂質を使用することが望ましい。リゾ化率は3〜25%が好ましく、5〜20%がより好ましい。これよりリゾ化率が低い場合は、キサントフィルを揮発性有機溶媒に溶解させる際、粘度が上昇する場合がある。また、これより多い場合は沈殿を発生する場合がある。   The egg yolk phospholipid used in the product of the present invention is a general term for phosphatidylcholine, phosphatidylethanolamine, sphingomyelin, and their lyso form, which are constituent lipids of egg yolk, and refers to a lipid composition mainly composed of these. The phospholipid content in the egg yolk phospholipid depends on the degree of purification, but when used in the present invention, it is preferably 60% or more, more preferably 80% or more. The phospholipid composition in egg yolk phospholipids is derived from egg yolk as a raw material, but the phospholipid content can be increased by removing other lipid components such as specific phospholipids and cholesterol by purification. By causing phospholipase A or the like to act on egg yolk phospholipids, a part or all of the lipase can be lysed. The lysolysis rate, that is, the mass percentage of lysophospholipid with respect to the total mass of phospholipid, can be adjusted by phospholipase A treatment conditions such as the kind, amount, treatment time, and temperature of the enzyme. Alternatively, the lysolysis rate can be adjusted as appropriate by uniformly mixing separately highly lysed phospholipids with untreated phospholipids at a specific ratio. In the present invention, it is desirable to use a partially lysed egg yolk phospholipid. The lysification rate is preferably 3 to 25%, more preferably 5 to 20%. When the lysification rate is lower than this, the viscosity may increase when xanthophyll is dissolved in the volatile organic solvent. Moreover, when more than this, precipitation may generate | occur | produce.

卵黄リン脂質の配合量は、キサントフィルの5〜50倍が好ましく、10〜30倍がさらに好ましい。また、粉末状組成物全量に対し、5〜30%が好ましく、15〜25%がさらに好ましい。   The blending amount of egg yolk phospholipid is preferably 5 to 50 times, more preferably 10 to 30 times that of xanthophyll. Moreover, 5-30% is preferable with respect to powdery composition whole quantity, and 15-25% is further more preferable.

本発明に用いる油脂とは、食用に用いられる油脂であれば特に制限はないが、常温で安定な懸濁液を得るために、融点の低い、つまり常温で液状を呈する油脂が好ましい。例えば、大豆油、菜種油、サフラワー油、ひまわり油、ベニバナ油、コーン油等の精製植物油が挙げられる。   The fats and oils used in the present invention are not particularly limited as long as they are edible fats and oils, but in order to obtain a suspension that is stable at room temperature, fats and oils having a low melting point, that is, liquids at room temperature are preferable. For example, refined vegetable oils such as soybean oil, rapeseed oil, safflower oil, sunflower oil, safflower oil, corn oil and the like can be mentioned.

本発明の粉末状組成物は、抗酸化活性の高いキサントフィルを有効成分として含むため、自ら酸化され力価が低減されやすい。そこで主剤安定化のため抗酸化剤を配合することができる。抗酸化剤は一般に食品で用いられるものであれば制限はないが、油脂に対する効果が高いものが好ましい。例えば、ビタミンE、マリーゴールド抽出物、ルチン等が挙げられる。中でもルチンが好ましい。ルチンはポリフェノールの一種で、そば等に多く含まれるフラボノイド系の色素であり、強い抗酸化活性を示す。   Since the powdery composition of the present invention contains xanthophyll having high antioxidant activity as an active ingredient, it is oxidized by itself and the titer is easily reduced. Therefore, an antioxidant can be added to stabilize the main agent. Antioxidants are not limited as long as they are generally used in foods, but those having a high effect on fats and oils are preferable. For example, vitamin E, marigold extract, rutin and the like can be mentioned. Of these, rutin is preferred. Rutin is a kind of polyphenol and is a flavonoid pigment that is abundant in buckwheat etc. and exhibits strong antioxidant activity.

本発明でいう食品組成物とは、本発明品である粉末状組成物を配合することより、加工工程を経て製造される食品をいう。主食であっては、パン、冷凍ピラフ、レトルトの粥、シリアル等、副菜にあっては、密封包装等加工された和食、洋食、中華の一般食品、惣菜、マヨネーズ、ドレッシング等の調味料、菓子、飲料、健康食品としてのサプリメント等をいう。   The food composition referred to in the present invention refers to a food produced through a processing step by blending the powdered composition which is the product of the present invention. For staple foods, bread, frozen pilaf, retort rice cake, cereal, etc. It means supplements such as confectionery, beverages, and health foods.

本発明である粉末状組成物の製造方法に用いる揮発性有機溶媒は、食品に用いることのできるエタノール、ヘキサン等が例に挙げられるが、残留を考慮しエタノールが好ましい。水系媒体としては水やこれに賦形剤や他の成分を溶解させたものをいう。賦形剤としては一般に粉末油脂を製造する時に用いられる賦形剤であって、例えばデキストリン、乳糖、結晶セルロース等の糖質およびカゼイン、卵白などのたんぱく質またはその加水分解物が挙げられる。   Examples of the volatile organic solvent used in the method for producing a powdery composition according to the present invention include ethanol and hexane that can be used in foods. Ethanol is preferable in consideration of the residue. The aqueous medium refers to water or a medium in which excipients and other components are dissolved. Excipients are generally used when producing powdered fats and oils, and examples thereof include carbohydrates such as dextrin, lactose and crystalline cellulose, proteins such as casein and egg white, and hydrolysates thereof.

次に、本発明の一般的な製造方法について記す。ルテインを約20%、ゼアキサンチンを約1%含有する油1重量部を、8〜12重量部のエタノールに分散させ60〜70℃まで加温する。次に一部リゾ化した卵黄リン脂質3〜4重量部、ビタミンE0.03〜0.05重量部を加え、溶解する。これに同温度に加温した清水120〜150重量部とこれに溶解させたデキストリン12〜15重量部を加え、10分〜2時間攪拌する。この粗懸濁液を高圧乳化機を用いて100〜250MPa(好ましくは150〜250MPa)の圧力で高圧処理することにより、微細化された懸濁液を得る。高圧乳化機として、例えば、マントン−ゴーリン型高圧ホモジナイザー、ジェット水流反転型高圧乳化機、マイクロフルイダイザー(マイクロフルディスク社製)、ナノマイザー(ナノマイザー社製)、アルティマイザー(スギノマシン社製)等を使用することができる。この懸濁液を凍結乾燥機、スプレードライヤー等の乾燥機を用い乾燥、脱水を行い、本発明品である粉末状組成物を得る。   Next, the general manufacturing method of the present invention will be described. 1 part by weight of oil containing about 20% lutein and about 1% zeaxanthin is dispersed in 8-12 parts by weight of ethanol and heated to 60-70 ° C. Next, 3-4 parts by weight of partially lysed egg yolk phospholipid and 0.03-0.05 part by weight of vitamin E are added and dissolved. To this, 120 to 150 parts by weight of fresh water heated to the same temperature and 12 to 15 parts by weight of dextrin dissolved therein are added and stirred for 10 minutes to 2 hours. This coarse suspension is subjected to high pressure treatment at a pressure of 100 to 250 MPa (preferably 150 to 250 MPa) using a high-pressure emulsifier to obtain a fine suspension. Examples of the high pressure emulsifier include a Menton-Gorin type high pressure homogenizer, a jet water flow reversal type high pressure emulsifier, a microfluidizer (manufactured by Microfull Disc), a nanomizer (manufactured by Nanomizer), and an optimizer (manufactured by Sugino Machine). Can be used. The suspension is dried and dehydrated using a dryer such as a freeze dryer or a spray dryer to obtain a powdery composition as the product of the present invention.

以下、本発明である粉末状組成物について、実施例等に基づき具体的に説明する。なお、本発明はこれらに限定するものではない。   Hereinafter, the powdery composition of the present invention will be specifically described based on examples and the like. In addition, this invention is not limited to these.

表1の配合について、上記方法に準じ、実施例1〜5及び比較例1を調製した。原料としては、キサントフィルとしてルテインは、遊離のルテインを20%含有する油(商品名「フローラGLOルテイン20%懸濁液」、Kemin Health, L.C.製)として配合した。なお、このルテイン含有油は通常、約1%のゼアキサンチンを含む。またこれとは別に、エステル体のルテイン20%を含有する油(商品名「ルテイン20」、協和発酵工業(株)製)を比較例に用いた。また、卵黄リン脂質として、コレステロールを除去し、リン脂質含量90%以上に精製した卵黄リン脂質(キユーピー(株)製)を、卵黄リゾリン脂質として、コレステロールを除去し、リゾリン脂質含量90%以上に精製した卵黄リゾリン脂質(キユーピー(株)製)を使用した。

得られた懸濁液を凍結乾燥法により、粉末状組成物を得た。
これらについて、高圧処理後の懸濁液の状態、懸濁液を凍結乾燥した粉末状組成物の状態、粉末状組成物を水に1%となるよう溶解した水溶液の状態について観察し、食品素材としての総合的な評価を行った。
About the mixing | blending of Table 1, Examples 1-5 and the comparative example 1 were prepared according to the said method. As raw materials, lutein as xanthophyll was blended as an oil containing 20% free lutein (trade name “Flora GLO Lutein 20% Suspension”, manufactured by Kemin Health, LC). This lutein-containing oil usually contains about 1% zeaxanthin. Separately, an oil containing 20% ester lutein (trade name “Lutein 20”, manufactured by Kyowa Hakko Kogyo Co., Ltd.) was used as a comparative example. Moreover, the egg yolk phospholipid (manufactured by Kewpie Co., Ltd.), which has been purified by removing cholesterol and having a phospholipid content of 90% or more as egg yolk phospholipid, is used to remove cholesterol from the egg yolk lysophospholipid to obtain a lysophospholipid content of 90% or more. Purified egg yolk lysophospholipid (manufactured by QP Corporation) was used.
99.5V / V% ethanol as a volatile organic solvent, vitamin E preparation as Vitamin E (trade name “Emix D”, manufactured by Tama Seikagaku Co., Ltd.), TK-16 as a dextrin (Matsuya Chemical Industry Co., Ltd.) Made).
The high-pressure treatment was performed using a jet water flow reversal type high-pressure emulsifier at a pressure of 200 MPa and a hot water temperature of 50 ° C.
The obtained suspension was freeze-dried to obtain a powdery composition.
Regarding these, the state of the suspension after the high-pressure treatment, the state of the powdered composition obtained by freeze-drying the suspension, and the state of the aqueous solution in which the powdered composition was dissolved in water to 1% were observed. As a comprehensive evaluation.
