Description

【0001】
【発明の属する技術分野】
本発明は、健康食品や保健機能食品(特定保健用食品、栄養機能食品)などの飲食品、医薬品などに使用することができる甘草疎水性抽出物含有油脂組成物に関する。
【0002】
【従来の技術】
甘草及びその水抽出物は、鎮痛鎮痙作用、去痰作用を持つ生薬として、あるいは食品として利用されている。また、その主成分であるグリチルリチン(グリチルリチン酸)にショ糖の約200倍の甘さがあることから、甘味料としても利用されている。
【0003】
一方、甘草または甘草水抽出残査から有機溶媒で抽出される甘草疎水性抽出物は、酸化防止作用、抗菌作用、酵素阻害作用、抗腫瘍作用、抗アレルギー作用、抗ウィルス作用など多くの有用作用を示すことが確認されている。更に最新の研究においては、血糖降下作用および脂質代謝改善作用を有することが見出されている(特出願2001−106216)。
【0004】
しかしながら、甘草疎水性抽出物は水および一般的な油にはほとんど溶解せず、また、有機溶媒抽出物のままでは固結し易い上に、着色など不安定なことが知られている。その為、取り扱い易く且つ安定な状態に製剤化することが必要とされるが、従来、抽出用溶剤として用いられてきたエタノール、プロピレングリコール、1,3−ブチレングリコールなどは、安定性が悪いことや食品への利用が制限されるなどの問題があった。
【0005】
これらを改善する試みとして、特許第2794433号には中鎖脂肪酸トリグリセライドの利用が、特開2000−239176には多価アルコール脂肪酸エステルの利用がそれぞれ開示されている。しかし中鎖脂肪酸トリグリセライドは、食用油として摂取した場合の肛門漏洩の問題、あるいは加熱調理に使用した場合の低い発煙点が問題であり、調理油として使用することは困難である。また、乳化剤としての多価アルコール脂肪酸エステルは界面活性が強く、油脂組成物の性状に大きな影響を及ぼすことや、乳化剤特有の異味が問題となる為に食品としての利用は限定されている。さらに溶解力の点で最適とされるジグリセリンモノイソステアリン酸エステルは食品には使用できない。
【0006】
一方、ジグリセライドは天然油脂中の副成分として、モノグリセライド、リン脂質等の複合脂質、遊離脂肪酸等とともに含まれるが、産業上は基剤として化粧品、医薬品等の分野で利用されており、食品分野においても油脂の物性改良剤や食用油脂として利用されている。
【0007】
【発明が解決しようとする課題】
上記のように甘草疎水性抽出物は、健康食品や保健機能食品(特定保健用食品、栄養機能食品)などの飲食品、医薬品として優れた効能を有するが、水および一般的な油にはほとんど溶解しない為に利用が困難であった。また、モノグリセライドが甘草疎水性抽出物を溶解することは一般に知られているが、その界面活性と乳化剤特有の異味、および常温でその結晶が析出する等の問題がある為、飲食品などに添加する場合の用途は限られる。従って本発明は、幅広く食品に使用できる安定で取り扱い性の良い甘草疎水性抽出物含有組成物を得ることを目的とする。
【0008】
【課題を解決するための手段】
本発明者らは、上記実情に鑑み鋭意研究を行った結果、甘草疎水性抽出物の溶剤としてジグリセライド混合物を用いることにより上述の目的を達成し、さらには通常の食用油脂が有するあらゆる用途にも使用できる食用油脂組成物であることを見出し本発明を完成するに至った。
【0009】
即ち、本発明の第1は、甘草疎水性抽出物をジグリセライド混合物に溶解してなる食用油脂組成物であって、食用油脂組成物中、甘草疎水性抽出物が食用油脂組成物100重量%に対して0.5重量%以上であり、且つジグリセライド混合物中、ジグリセライド含量が20重量%以上、トリグリセライド含量が60重量%以下であることを特徴とする食用油脂組成物に関するものであり、好ましくは甘草疎水性抽出物が、グリキルリーザ ウラレンシス、又はグリキルリーザ グラブラからの抽出物であ。本発明の第2は前記食用油脂組成物を用いる油脂利用食品に関するものである。
【0010】
【発明の実施の形態】
以下に、本発明の実施の形態を詳しく説明する。本発明で使用される甘草疎水性抽出物を溶解させる溶剤は、ジグリセライド混合物であり、混合物中のジグリセライド以外の成分はモノグリセライド及びトリグリセライドである。食用油脂組成物中、甘草疎水性抽出物が食用油脂組成物100重量%に対して0.5重量%以上でり、且つジグリセライド含量は20重量%以上であることが好ましい。甘草疎水性抽出物が食用油脂組成物100重量%に対して0.5重量%未満であれば、血糖降下作用および脂質代謝改善作用等の効果が十分発揮されない場合がある。またジグリセライド含量が20重量%未満であれば、甘草疎水性抽出物を溶解する効果が十分に発揮されない、或いは甘草疎水性抽出物の結晶が析出するなどして飲食品として不適な場合がある。一方、モノグリセライド含量は最終食品の形態によって決定される為、特に限定されないが、ジグリセライド混合物中50重量%以下、好ましくは20重量%以下である。モノグリセライド含量が50重量%を越えると、常温においてモノグリセライドの結晶が析出する為、取り扱い性が悪い場合がある。また、残余のトリグリセライド含量はジグリセライド混合物中80重量%以下、好ましくは60重量%以下である。トリグリセライド含量が80重量%を超えると甘草疎水性抽出物の溶解性が低下し、結晶が析出する場合がある。また、グリセライドを構成する脂肪酸残基は、炭素数が8〜24のものが例示されるが、用途に応じてそれらの飽和脂肪酸、不飽和脂肪酸を選択することが可能である。例えば、フライ油用途の場合は不飽和脂肪酸であることが好ましく、可塑性油脂の場合は飽和脂肪酸を含んでも良い。この様なジグリセライド混合物は、例えば脂肪酸とグリセリンのエステル化、油脂類とグリセリンのエステル交換等によって製造できるが、本発明はジグリセライド混合物の製造方法、精製方法、履歴によって何ら限定されるものではない。
【0011】
本発明に用いる甘草は、マメ科カンゾウ属(Glycyrrhiza属)の植物、例えば、Glycyrrhiza uralensis(G.uralensis,グリキルリーザ ウラレンシス)、G.inflata(グリキルリーザ インフラータ)、G.glabra(グリキルリーザ グラブラ)、G.eurycarpa(グリキルリーザ ユーリカルパ)、G.aspera(グリキルリーザ アスペラ)などであり、好ましくはグリキルリーザ ウラレンシス、グリキルリーザ インフラータ、グリキルリーザ グラブラなどである。甘草は、古くから食経験がある食品であり、食品添加物や生薬としても利用されている。
【0012】
また、本発明に用いる甘草疎水性抽出物は、甘草またはその粉末から有機溶媒を用いて抽出することにより得ることができる。あるいは、甘草またはその粉末から予め水などで親水性成分を抽出・除去した水抽出残渣、またはその残渣を乾燥させたものから有機溶媒を用いて抽出することにより得ることができる。
【0013】
ここで用いる有機溶媒は、医薬品や食品添加物などの製造、加工に使用が許可されたものが好ましく、例えば、アセトン、エタノール、グリセリン、酢酸エチル、ジエチルエーテル、ブタノール、プロパノール、プロピレングリコール、メタノールなどが挙げられる。また、これらの溶媒のうち少なくとも2種以上を混合して用いてもよいし、これらの含水溶媒を用いてもよい。さらに、単一溶媒で甘草の疎水性成分を効率よく抽出するためには、エタノール、アセトン、酢酸エチルなどが好ましい。この様にして得た甘草疎水性抽出物は、医薬品や食品として不適当な不純物を含有しない限り、粗抽出物または半精製抽出物として本発明に使用できるが、必要に応じて脱色、脱臭など精製処理を行っても良い。
【0014】
また、本発明の甘草疎水性抽出物にはフラボノイド成分として、グリシクマリン(glycycoumarin)、グリシロール(glycyrol)、グリシリン(glycyrin)、リクイリチゲニン(liquiritigenin)、グリコリコン(glicoricone)、グラブリジン(glabridin)、グリウラリンB(glyurallin B)、リコクマロン(licocoumarone)、ガンカオニンI(gancaonin I)、デヒドログリアスペリンD(dehydroglyasperin D)、エチナチン(echinatin)、イソリコフラボノール(isolicoflavonol)、デヒドログリアスペリンC(dehydroglyasperin C)、グリアスペリンB(glyasperin B)、グリチルイソフラバノン(glycyrrhisoflavanone)、ルピワイテオン(lupiwighteone)、グリアスペリンD(glyasperin D)、セミリコイソフラボンB(semilicoisoflavone B)などを含む。
【0015】
甘草疎水性抽出物とジグリセライド混合物から本発明の食用油脂組成物を得るには、グリセライド混合物に甘草疎水性抽出物を加え均一な状態になるまで撹拌すればよく、溶解促進には30℃以上、好ましくは40℃〜60℃の加温が有効である。また、エタノール等の有機溶媒に溶解した状態の甘草疎水性抽出物をグリセライド混合物に加えて混合した後、有機溶媒を留去しても良い。
【0016】
本発明の食用油脂組成物は、単独で調理用やソフトカプセル等の製剤へ利用してもよいが、油性の対象物と自由に混和することが出来る為、目的に応じて他の食用油脂を混合して物性を調整油脂利用食品とすることが可能である。この場合、他の食用油脂の種類および使用量は、製品に要求される個々の物性、使用温度域等の諸条件を考慮して決定され、その種類および添加量を調整することによって、稠度や融点等の特性をコントロールする事が出来る。例えばコーン油、ナタネ油、ハイエルシンナタネ油、大豆油、オリーブ油、紅花油、綿実油、ヒマワリ油、米糠油、パーム油、パーム核油等の植物油、魚油、牛脂、豚脂、乳脂、卵黄油等の動物油、またはこれらを原料として分別、水添、エステル交換等を行った油脂、或いはこれらの混合油が使用できる。また、ソフトカプセルなどの製剤を作製する際に、本発明の食用油脂組成物の取り扱いを良くするためには、ジグリセライド混合物の流動性が重要であり、融点の高いモノグリセリド含量は少ない方が良い。更にフライ油としては、モノグリセライドはフライ油全体中の2重量%未満が好ましいとされる。
【0017】
この様にして得られる食用油脂組成物は、フライ油等の液状油脂、マーガリン、ショートニング等の可塑性油脂としての利用や油中水型エマルション、水中油型エマルションへ利用することができる。また、これらを原材料にして製造される本発明の油脂利用食品は、チューインガム、チョコレート、キャンディー、ゼリー、ビスケット、クラッカーなどの菓子類、アイスクリーム、氷菓などの冷菓類、茶、清涼飲料、栄養ドリンク、美容ドリンクなどの飲料、うどん、中華麺、スパゲティー、即席麺などの麺類、蒲鉾、竹輪、半片などの練り製品、パン、ハム、スープ、およびドレッシング、マヨネーズ、ソースなどの調味料などが例示され、ペットフードや家畜飼料等へも利用可能である。
【0018】
更に栄養強化を目的とした各種ビタミン類、例えばビタミンA,D,E等を添加、併用しても良いし、呈味剤としての各種香料、乳関連物質、例えば全脂粉乳、脱脂粉乳、発酵乳、各種塩類、乳脂肪等を添加、併用しても良い。また、上記以外の原材料としては、通常の油中水型エマルション、水中油型エマルションに使用される酸化防止剤、着色剤等が全て使用可能である。

BACKGROUND OF THE INVENTION
The present invention relates to a licorice hydrophobic extract-containing oil and fat composition that can be used for foods and drinks such as health foods and health function foods (foods for specified health use, foods for nutritional function), pharmaceuticals, and the like.
[0002]
[Prior art]
Licorice and its water extract are used as herbal medicines having analgesic and antispasmodic and expectorant actions, or as foods. In addition, glycyrrhizin (glycyrrhizic acid), which is the main component, is about 200 times sweeter than sucrose, and is also used as a sweetener.
[0003]
On the other hand, hydrophobic extract of licorice extracted from licorice or licorice water extract with organic solvent has many useful effects such as antioxidant, antibacterial, enzyme inhibitory, antitumor, antiallergic and antiviral effects. It has been confirmed that Furthermore, in the latest research, it has been found that it has a hypoglycemic effect and a lipid metabolism improving effect (Japanese Patent Application No. 2001-106216).
[0004]
However, it is known that the hydrophobic extract of licorice hardly dissolves in water and general oils, and is easy to solidify with an organic solvent extract as well as unstable such as coloring. Therefore, it is necessary to formulate it in a stable state that is easy to handle, but ethanol, propylene glycol, 1,3-butylene glycol, etc., which have been used as extraction solvents in the past, have poor stability. There was a problem that the use to food and food was restricted.
[0005]
As attempts to improve these, Japanese Patent No. 2794433 discloses the use of medium-chain fatty acid triglycerides, and Japanese Patent Application Laid-Open No. 2000-239176 discloses the use of polyhydric alcohol fatty acid esters. However, medium chain fatty acid triglycerides have problems of anal leakage when ingested as an edible oil, or a low smoke point when used for cooking, and are difficult to use as cooking oil. In addition, polyhydric alcohol fatty acid ester as an emulsifier has a strong surface activity and has a great influence on the properties of the oil and fat composition, and the unique taste of the emulsifier becomes a problem. Furthermore, diglycerin monoisostearate, which is optimal in terms of dissolving power, cannot be used in foods.
[0006]
On the other hand, diglyceride is included as a minor component in natural fats and oils, together with complex lipids such as monoglycerides and phospholipids, free fatty acids, etc., but industrially used as a base in the fields of cosmetics, pharmaceuticals, etc. Is also used as an oil physical property improver and edible fat.
[0007]
[Problems to be solved by the invention]
As described above, the licorice hydrophobic extract has excellent effects as foods and drinks such as health foods and health functional foods (food for specified health use, nutritional functional foods), and pharmaceuticals. It was difficult to use because it did not dissolve. In addition, it is generally known that monoglyceride dissolves hydrophobic extract of licorice, but it is added to foods and drinks because of its surface activity, emulsification peculiar to emulsifiers, and precipitation of crystals at room temperature. Applications are limited. Accordingly, an object of the present invention is to obtain a licorice hydrophobic extract-containing composition that is stable and easy to handle and can be used in a wide range of foods.
[0008]
[Means for Solving the Problems]
As a result of diligent research in view of the above circumstances, the present inventors have achieved the above-mentioned object by using a diglyceride mixture as a solvent for a licorice hydrophobic extract, and also for all uses of ordinary edible oils and fats. It discovered that it was an edible oil-fat composition which can be used, and came to complete this invention.
[0009]
That is, the first of the present invention is an edible oil / fat composition obtained by dissolving a licorice hydrophobic extract in a diglyceride mixture , wherein the licorice hydrophobic extract is 100% by weight in the edible oil / fat composition. The edible oil / fat composition has a diglyceride content of 20% by weight or more and a triglyceride content of 60% by weight or less in a diglyceride mixture, preferably 0.5% by weight or more , preferably licorice hydrophobic extract, Ru extract der from Gurikiruriza uralensis, or Gurikiruriza glabra. The 2nd of this invention is related with the oil-fat utilization foodstuff using the said edible oil-fat composition.
[0010]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail. The solvent for dissolving the licorice hydrophobic extract used in the present invention is a diglyceride mixture, and the components other than the diglyceride in the mixture are monoglyceride and triglyceride. In the edible oil / fat composition, the licorice hydrophobic extract is preferably 0.5% by weight or more with respect to 100% by weight of the edible oil / fat composition, and the diglyceride content is preferably 20% by weight or more. If the licorice hydrophobic extract is less than 0.5% by weight with respect to 100% by weight of the edible oil / fat composition, effects such as a hypoglycemic action and a lipid metabolism improving action may not be sufficiently exhibited. On the other hand, if the diglyceride content is less than 20% by weight, the effect of dissolving the licorice hydrophobic extract may not be sufficiently exhibited, or crystals of the licorice hydrophobic extract may precipitate, making it unsuitable as a food or drink. On the other hand, since the monoglyceride content is determined by the form of the final food and is not particularly limited, it is 50% by weight or less, preferably 20% by weight or less in the diglyceride mixture. When the monoglyceride content exceeds 50% by weight, the monoglyceride crystals are precipitated at room temperature, which may cause poor handling. The residual triglyceride content is 80% by weight or less, preferably 60% by weight or less in the diglyceride mixture. When the triglyceride content exceeds 80% by weight, the solubility of the licorice hydrophobic extract is lowered, and crystals may precipitate. Moreover, although the fatty acid residue which comprises a glyceride is a C8-C24 thing is illustrated, it is possible to select those saturated fatty acids and unsaturated fatty acids according to a use. For example, unsaturated fatty acids are preferable for frying oil applications, and saturated fatty acids may be included for plastic fats and oils. Such a diglyceride mixture can be produced by, for example, esterification of a fatty acid and glycerin, transesterification of fats and oils and glycerin, etc., but the present invention is not limited in any way by the production method, purification method, and history of the diglyceride mixture.
[0011]
The licorice used in the present invention is a plant belonging to the genus Glycyrrhiza, such as Glycyrrhiza urarensis (G. uralensis, Glykyrrhiza urarensis), G. inflata, G.K. glabra, G. eurycarpa, G.K. aspera (Glyquilliza aspera), preferably glycyrrhizara urarensis, glycyrrhiza inflanta, glycyrrhiza grabra, and the like. Licorice is a food that has long been eaten, and is also used as a food additive and herbal medicine.
[0012]
Moreover, the licorice hydrophobic extract used for this invention can be obtained by extracting from a licorice or its powder using an organic solvent. Alternatively, it can be obtained by extracting from a licorice or its powder with an organic solvent from a water extraction residue obtained by previously extracting and removing a hydrophilic component with water or the like, or a residue obtained by drying the residue.
[0013]
The organic solvent used here is preferably one that is permitted for use in the manufacture and processing of pharmaceuticals and food additives, such as acetone, ethanol, glycerin, ethyl acetate, diethyl ether, butanol, propanol, propylene glycol, methanol, etc. Is mentioned. Moreover, at least 2 or more types may be mixed and used among these solvents, and these water-containing solvents may be used. Furthermore, ethanol, acetone, ethyl acetate and the like are preferable for efficiently extracting the hydrophobic component of licorice with a single solvent. The licorice hydrophobic extract thus obtained can be used in the present invention as a crude extract or semi-purified extract as long as it does not contain impurities that are inappropriate for pharmaceuticals and foods. A purification treatment may be performed.
[0014]
In addition, the licorice hydrophobic extract of the present invention contains, as flavonoid components, glycycoumarin, glycyrol, glycyrin, liquiritigenin, glycorin, glycridine, B), lycocoumarone, gankaonin I, dehydrogliasperin D, ethinatin, isolicoflavonol, dehydrogliasperin C (dehri sperin C) g lysperin B), glycyrrisoflavanone, lupiwiteone, glyasperin D, semi-lysoisoflavone B, and the like.
[0015]
In order to obtain the edible oil / fat composition of the present invention from the licorice hydrophobic extract and the diglyceride mixture, the licorice hydrophobic extract may be added to the glyceride mixture and stirred until it is uniform. Preferably, heating at 40 ° C. to 60 ° C. is effective. Moreover, after adding the licorice hydrophobic extract in the state melt | dissolved in organic solvents, such as ethanol, to a glyceride mixture, you may distill off an organic solvent.
[0016]
The edible oil / fat composition of the present invention may be used alone for preparations such as cooking and soft capsules, but can be freely mixed with oily objects, so other edible oils / fats can be mixed depending on the purpose. Thus, it is possible to obtain a food using adjusted fats and oils. In this case, the type and amount of other edible fats and oils are determined in consideration of various physical properties required for the product, various conditions such as the operating temperature range, etc., and by adjusting the type and amount added, consistency and Properties such as melting point can be controlled. For example, vegetable oils such as corn oil, rapeseed oil, hay rapeseed oil, soybean oil, olive oil, safflower oil, cottonseed oil, sunflower oil, rice bran oil, palm oil, palm kernel oil, fish oil, beef tallow, pork fat, milk fat, egg yolk oil, etc. Animal oils, oils and fats subjected to fractionation, hydrogenation, transesterification, etc., or a mixed oil thereof can be used. Further, when preparing a preparation such as a soft capsule, the fluidity of the diglyceride mixture is important and the monoglyceride content having a high melting point is preferably small in order to improve the handling of the edible oil / fat composition of the present invention. Further, as the frying oil, the monoglyceride is preferably less than 2% by weight in the whole frying oil.
[0017]
The edible oil / fat composition thus obtained can be used as liquid oil / fat such as frying oil, plastic oil / fat such as margarine, shortening, water-in-oil emulsion, and oil-in-water emulsion. In addition, the fat and oil-based foods of the present invention produced using these as raw materials include confectionery such as chewing gum, chocolate, candy, jelly, biscuits and crackers, frozen confectionery such as ice cream and ice confectionery, tea, soft drinks, and energy drinks Examples include beverages such as beauty drinks, noodles such as udon, Chinese noodles, spaghetti, instant noodles, kneaded products such as strawberries, bamboo rings, and half pieces, breads, hams, soups, and seasonings such as dressings, mayonnaise, sauces, etc. It can also be used for pet food and livestock feed.
[0018]
Furthermore, various vitamins for the purpose of fortification, such as vitamins A, D, E, etc. may be added and used together. Various flavorings as flavoring agents, milk-related substances such as whole milk powder, skimmed milk powder, fermentation Milk, various salts, milk fat and the like may be added and used in combination. Moreover, as raw materials other than those described above, all of antioxidants, colorants and the like used in ordinary water-in-oil emulsions and oil-in-water emulsions can be used.
