Description

健康機能成分を吸着・濃縮した乾燥脱脂穀類糠、該糠から調製した健康機能成分の濃縮物、及びそれらの製造方法Dried defatted cereal meal with adsorbed and concentrated health functional ingredients, concentrate of health functional ingredients prepared from the meal, and methods for producing them
　本発明は、γオリザノール、トコフェロール、ポリフェノール類等の極性のある健康機能成分を吸着・濃縮した乾燥脱脂穀類糠、該糠から調製した該健康機能成分の濃縮物；該健康機能成分が吸着・濃縮された乾燥脱脂穀類糠又は健康機能成分の濃縮物からなる極性のある健康機能成分含有飲食品用、医薬用、医薬部外品用、化粧品用、動物飼料用、又は水産飼料用素材；及びそれらの製造方法に関する。 The present invention relates to a dried defatted cereal meal obtained by adsorbing and concentrating a polar health function ingredient such as γ-oryzanol, tocopherol, polyphenols, etc., a concentrate of the health function ingredient prepared from the koji; A material for polar health function ingredient-containing foods, medicines, quasi-drugs, cosmetics, animal feeds, or aquatic feeds composed of a dried defatted cereal meal or a concentrate of health function ingredients; It relates to the manufacturing method.
　従来より、米糠等を原料として、米油等の植物油が製造されている。近年の研究により、この米油等植物油の原料となる米糠等には、γオリザノール、トコフェロール、ポリフェノール等の有用な健康機能成分が含まれていることが確認されている。例えば、γオリザノールについては、生長促進作用、性腺刺激作用、ビタミンＥ様作用、抗ストレス作用、脱コレステロール作用、抗高脂血症等の薬理作用や、抗酸化作用、紫外線吸収作用、チロシナーゼ活性抑制作用、皮膚温上昇作用等の生理活性作用が知られている。また、トコフェロールについては、脂質代謝改善作用、膜安定化作用、内分泌賦活作用、性機能向上作用、免疫増強作用、創傷修復作用、放射線障害防御作用、抗老化作用等が、カテキン類等のポリフェノールについては、抗菌活性、抗酸化活性、抗う食活性、抗ウイルス活性、抗アレルギー活性、α－アミラーゼ阻害活性、血圧上昇抑制作用、血中コレステロール低下作用等の生理活性作用が知られている。 Conventionally, vegetable oils such as rice oil have been produced using rice bran as a raw material. Recent research has confirmed that rice bran, which is a raw material for vegetable oils such as rice oil, contains useful health functional ingredients such as γ-oryzanol, tocopherol, and polyphenol. For example, for γ-oryzanol, growth promoting action, gonadal stimulating action, vitamin E-like action, anti-stress action, decholesterol action, anti-hyperlipidemia and other pharmacological actions, antioxidant action, ultraviolet absorption action, tyrosinase activity suppression Physiologically active actions such as action and skin temperature raising action are known. In addition, for tocopherol, lipid metabolism improving effect, membrane stabilizing effect, endocrine stimulating effect, sexual function improving effect, immune enhancing effect, wound repair effect, radiation damage protective effect, anti-aging effect, etc. are related to polyphenols such as catechins Is known to have physiological activities such as antibacterial activity, antioxidant activity, anti-cariogenic activity, antiviral activity, antiallergic activity, α-amylase inhibitory activity, blood pressure increase inhibitory effect, blood cholesterol lowering effect and the like.
　γオリザノール等の生理活性物質は、米糠等に多く含まれるものであるが、従来行なわれていた米油等の製造方法においては、これらの生理活性物質を、該食油中に残存させて、精製することが難しく、食油の利用に際してこれらの生理活性物質を有効に利用することができなかった。すなわち、従来、米油等の精製法としては、アルカリ精製法と蒸留脱酸法とが知られているが、アルカリ精製法においては、採油；脱ガム；脱ロウ；アルカリ脱酸；脱色；脱臭の工程において、γオリザノールが、油脂相から油滓に移行してしまい、アルカリ脱酸油には、極微量のγオリザノールしか残存しなかった。一方、蒸留脱酸法においては、アルカリ精製法におけるアルカリ脱酸に代えて、蒸留によって脂肪酸を除去しようとするものであり、高温真空蒸留によって、遊離脂肪酸を留去し、かつ、γオリザノールを油脂相に残存せしめる。しかし、この方法では、その後の脱臭工程においてγオリザノールの消失を防ぐためには、通常よりも低温での脱臭工程を経なければならず、このような脱臭処理では、良好な風味の油脂を得るのが難しく、γオリザノールを含有し、しかも、良好な風味の油脂を製造することは難かしかった。 Physiologically active substances such as γ oryzanol are abundantly contained in rice bran and the like. However, in the conventional methods for producing rice oil and the like, these physiologically active substances are left in the cooking oil and purified. It was difficult to use these physiologically active substances when using edible oil. That is, conventionally, as a method for refining rice oil or the like, an alkali refining method and a distillation deoxidation method are known. In the alkali refining method, oil collection; degumming; dewaxing; alkaline deoxidation; decolorization; deodorization. In this step, γ oryzanol was transferred from the oil phase to the oil cake, and only a very small amount of γ oryzanol remained in the alkaline deoxidized oil. On the other hand, in the distillation deoxidation method, instead of the alkali deoxidation in the alkali refining method, fatty acids are to be removed by distillation, free fatty acids are distilled off by high-temperature vacuum distillation, and γ-oryzanol is removed from oils and fats. Let it remain in the phase. However, in this method, in order to prevent the disappearance of γ-oryzanol in the subsequent deodorization process, a deodorization process at a temperature lower than usual must be performed. In such a deodorization process, fats and oils having a good flavor are obtained. However, it was difficult to produce oils and fats containing γ oryzanol and having a good flavor.
　そこで、米糠等に含まれるγオリザノール等の健康機能物質を有効に利用するために、従来より、該成分を含有する食用油等の各種の調製方法が提案されている。例えば、特開平６－３４０８８９号公報には、米糠原油を精製するに際し、真空下で水蒸気蒸留により、含有される脂肪酸除去し、オリザノール類を濃縮させた米油を製造する方法が開示されている。また、特開２０００－１１９６８１号公報には、米糠から油を抽出する際に、米糠を予めアミラーゼ、セルラーゼ、ヘミセルラーゼ、プロテアーゼ等の酵素を用いて処理し、炭化水素系有機溶剤で抽出することにより、オリザノールやステロールを１．８重量％以上含有する生理活性米糠油を製造することについて、特開２００２－２３８４５５号公報には、米糠原料から原油を抽出し、該原油の脱ガム、脱ロウ、脱酸工程を経て、原油を精製する米油の製造方法において、原油を２１０～２５０℃の蒸留温度で真空状態で蒸留し、更に、アルカリ処理して脱酸し、或いは原油の脱ガム、脱ロウ、脱臭工程を経て、原油を精製する米油の製造方法において、原油を減圧下、２５０℃以下で蒸留することにより脱臭し、γオリザノールやトコフェノール、ステロール等を含有する米油を製造する方法が開示されている。 Therefore, in order to effectively use health functional substances such as γ-oryzanol contained in rice bran and the like, various methods for preparing edible oils and the like containing the components have been proposed. For example, Japanese Patent Laid-Open No. 6-340889 discloses a method for producing rice oil in which oryzanols are concentrated by removing fatty acids contained therein by steam distillation under vacuum when refining rice bran crude oil. . Japanese Patent Laid-Open No. 2000-119682 discloses that when extracting oil from rice bran, the rice bran is previously treated with an enzyme such as amylase, cellulase, hemicellulase, protease, and extracted with a hydrocarbon-based organic solvent. JP-A-2002-238455 discloses a method for producing a bioactive rice bran oil containing 1.8% by weight oryzanol or sterol by extracting a crude oil from a rice bran raw material, and degumming and dewaxing the crude oil. In the method for producing rice oil through which the crude oil is refined through the deoxidation step, the crude oil is distilled in a vacuum state at a distillation temperature of 210 to 250 ° C., and further subjected to alkali treatment for deoxidation, or crude oil degumming, In a method for producing rice oil that undergoes a dewaxing and deodorizing process and refines crude oil, the crude oil is deodorized by distillation at 250 ° C. or less under reduced pressure, and γ-Oryzanol and Tokov Nord, a method for producing a rice oil containing sterols and the like are disclosed.
　また、特開２００２－２９３７９３号公報、特開２００４－３０００３４号公報には、米糠油ソープストックに水酸化ナトリウムのようなアルカリを加えて鹸化し、脱水した鹸化ソープストックを、酢酸エチル、アセトンのような有機溶媒で抽出してオリザノール富化フラクションを得、更には、カラムクロマトグラフィーにかけて、オリザノール富化画分を得る方法について、特開２００７－１２４９１７号公報には、米糠から製造される米油を原料として、アルカリ抽出、或いは、リパーゼのような酵素で処理して、高濃度のオリザノールを含有する米油を製造する方法について開示されている。これらの従来の方法は、米糠等に含まれるγオリザノール等の健康機能物質を利用するために、該成分を含有する食用油として調製するものであるが、いずれも複雑な処理を必要とするため、実用的な食用油の製造方法としては適用性に欠け、しかも、かかる方法で調製される製品は、いずれも食用油の形であるため、これを食品や医薬、或いは化粧品や飼料等の各種の用途における機能性素材として用いる場合に、その利用対象が制限され、利用上制約があった。 In addition, JP 2002-293793 A and JP 2004-300034 A disclose that a saponified soap stock which has been saponified by adding an alkali such as sodium hydroxide to rice bran oil soap stock and dehydrated with ethyl acetate and acetone. Japanese Patent Application Laid-Open No. 2007-124917 discloses a rice oil produced from rice bran for a method for obtaining an oryzanol-enriched fraction by extraction with such an organic solvent, and further obtaining an oryzanol-enriched fraction by column chromatography. Is used to produce rice oil containing a high concentration of oryzanol by alkaline extraction or treatment with an enzyme such as lipase. These conventional methods are prepared as edible oils containing the components in order to use health functional substances such as γ-oryzanol contained in rice bran etc., but both require complicated processing. In addition, as a practical method for producing edible oil, the applicability is lacking, and since the products prepared by such a method are all in the form of edible oil, they are used in various forms such as food, medicine, cosmetics and feed. When it is used as a functional material in the above-mentioned applications, its use target is limited, and there are restrictions on use.
　他方で、米糠のような穀類糠を、各種成分の吸着担体として用いることが知られている。例えば、特開平９－１８２５６２号公報には、コレステロールを含む動物性液化脂肪物質に、大豆、菜種、綿実、米糠のような油糧植物の種子又は油脂を抽出した油糧植物残滓を接触させることによって、コレステロールを吸着させ、このコレステロールを吸着させた油糧植物残滓を動物性液化脂肪物質から分離することによりコレステロールを除去する方法が開示されている。また、特開２００４－３２９０１９号公報には、脱脂糠やパーライトのようなグリセリン吸着担体とグリセリンとを混合して、グリセリン吸着担体にグリセリンを吸着させ、グリセリン吸着飼料を調製する方法が開示されている。しかしながら、米糠のような穀類糠を、γオリザノール等の健康機能物質の吸着に用い、該成分の精製・濃縮に用いるようなことについては知られていなかった。 On the other hand, it is known to use cereal meal such as rice bran as an adsorption carrier for various components. For example, in Japanese Patent Application Laid-Open No. 9-182562, an animal liquefied fatty substance containing cholesterol is contacted with oil plant seeds such as soybeans, rapeseed, cottonseed, rice bran or oily plant residues extracted from fats and oils. Thus, there is disclosed a method of removing cholesterol by adsorbing cholesterol and separating the oily plant residue adsorbed with cholesterol from animal liquefied fatty substances. Japanese Patent Application Laid-Open No. 2004-329019 discloses a method of preparing a glycerin-adsorbed feed by mixing glycerin adsorbing carrier such as defatted lees and perlite with glycerin and adsorbing glycerin on the glycerin adsorbing carrier. Yes. However, it has not been known that cereal meal such as rice bran is used for adsorbing health functional substances such as γ-oryzanol and used for purification and concentration of the component.

　［乾燥脱脂米糠を用いた健康機能成分の吸着］ [Adsorption of health functional ingredients using dry defatted rice bran]
　（乾燥脱脂米糠の調製）
米糠を順次ｎ－ヘキサン、ｎ－ヘキサンエタノール混合液、エタノール、水にて十分に洗浄し、極性の低いトリグリセリドや極性の高いフェルラ酸までほぼ全ての脂溶性成分を除去した。得られた完全脱脂米糠を１００℃で２４時間乾燥し、乾燥米糠を得た。 (Preparation of dry defatted rice bran)
The rice bran was washed thoroughly with n-hexane, n-hexane ethanol mixed solution, ethanol and water in order to remove almost all fat-soluble components from tripolar glycerides and ferulic acids with high polarity. The obtained completely defatted rice bran was dried at 100 ° C. for 24 hours to obtain dried rice bran.
　（健康機能成分含有抽出液の調製）
γオリザノールを含む市販米糠油を、ヘキサンにて抽出し、ｎ－ヘキサン飽和溶液を作成した。 (Preparation of extract containing health functional ingredients)
Commercial rice bran oil containing γ-oryzanol was extracted with hexane to prepare a saturated n-hexane solution.
　（吸着処理と結果）
調製された乾燥米糠に対して体積換算で５倍量のγオリザノールｎ－ヘキサン飽和溶液を加え、３０分間振とう攪拌した。これをｎ－ヘキサンで十分に洗浄し、過剰のγオリザノールを除去した。次いで、クロロホルムメタノールにて乾燥米糠に吸着したγオリザノールを完全に採取した。得られたγオリザノール抽出液をロータリーエバポレーター及び真空乾燥機にて完全に乾固し、その重量を測定した。その結果、乾燥米糠１ｇ当たり１．６７±０．１８ｍｇのγオリザノールが吸着していた（図１：γオリザノールを付加した脱脂米糠から再回収したγオリザノール）。乾重量１ｇあたりの脱脂米糠のγオリザノール含量が最大で８０μｇ程度であることから、２０倍もの強化が可能であることが明らかとなった。このように、脱脂米糠はγオリザノール強化担体としての利用が可能であることが確認された。 (Adsorption treatment and results)
To the prepared dried rice bran, 5 times volume of γ-oryzanol n-hexane saturated solution in terms of volume was added, and the mixture was shaken and stirred for 30 minutes. This was thoroughly washed with n-hexane to remove excess γ-oryzanol. Subsequently, γ oryzanol adsorbed on the dried rice bran with chloroform methanol was completely collected. The obtained γ-oryzanol extract was completely dried using a rotary evaporator and a vacuum dryer, and the weight was measured. As a result, 1.67 ± 0.18 mg of γ oryzanol was adsorbed per 1 g of dried rice bran (FIG. 1: γ oryzanol recovered again from defatted rice bran added with γ oryzanol). Since the maximum γ oryzanol content of defatted rice bran per gram of dry weight is about 80 μg, it was revealed that it can be strengthened 20 times. Thus, it was confirmed that defatted rice bran can be used as a γ-oryzanol-enhanced carrier.
　植物性ステロール及びαトコフェロールについても同様の検討を行ったところ、米糠１ｇ当たりそれぞれ０．８１±０．１１及び０．５８±０．０８ｍｇの植物性ステロール及びαトコフェロールが吸着された。更に、油脂１ｇ当たり１４ｍｇのγオリザノールを含む市販米糠油ヘキサン溶液に本担体を用いたところ、γオリザノールを米糠１ｇ当たり２．３０±０．２７ｍｇ吸着し、結果的に油脂１ｇ当たり４８０ｍｇまで濃縮することができた。γオリザノール単独で吸着試験を行った際よりも吸着量が増加したのは、米糠油にトリグリセリドなどの他の成分が存在することでｎ－ヘキサンへのγオリザノール溶解量が増大したため、吸着量も増えたものと予想される。 When the same examination was conducted on plant sterol and α-tocopherol, 0.81 ± 0.11 and 0.58 ± 0.08 mg of plant sterol and α-tocopherol were adsorbed per 1 g of rice bran, respectively. Furthermore, when this carrier was used in a commercially available rice bran oil hexane solution containing 14 mg of γ oryzanol per gram of fat and oil, 2.30 ± 0.27 mg of γ oryzanol was adsorbed per gram of rice bran and consequently concentrated to 480 mg per gram of fat and oil. I was able to. The amount of adsorption increased compared to the case where the adsorption test was performed with γ oryzanol alone, because the amount of γ oryzanol dissolved in n-hexane increased due to the presence of other components such as triglyceride in rice bran oil. Expected to have increased.
　［乾燥脱脂米糠を用いた健康機能成分の吸着と分離・濃縮］
米糠をｎ－ヘキサン、ジエチルエーテル、エタノールにて順次１０回以上洗浄した後、図２（脱脂米糠充填カラム）のようにガラスカラム内に充填した。クロロホルムメタノールによって乾燥利尻昆布から抽出した全脂質を重層し、１０カラム容のジエチルエーテルを流した。その後、ジエチルエーテル・エタノール混液（９８：２）にて溶出される画分をＴＬＣにて検出した。 [Adsorption, separation and concentration of health functional ingredients using dried defatted rice bran]
The rice bran was washed successively with n-hexane, diethyl ether and ethanol 10 times or more, and then packed into a glass column as shown in FIG. 2 (defatted rice bran packed column). Total lipids extracted from dried Rishiri kelp with chloroform methanol were overlaid, and 10 column volumes of diethyl ether were flowed. Thereafter, the fraction eluted with diethyl ether / ethanol mixture (98: 2) was detected by TLC.
　図３（ジエチルエーテル・エタノールにて溶出された画分の紫外蛍光像（左）及び硫酸検出像（右））に示すように、脱脂米糠に吸着されたγオリザノールがジエチルエーテル・エタノール混液にて溶出されることが明らかとなった。したがって、脱脂米糠は化学修飾を施すことなく、植物性ステロール、γオリザノールやクロロフィルなどの比較的極性の高い成分を特異的に吸着することが明らかとなった。これを利用してこれらの健康機能物質を脱脂米糠に濃縮することが可能である。 As shown in FIG. 3 (ultraviolet fluorescence image (left) and sulfuric acid detection image (right) of the fraction eluted with diethyl ether / ethanol), γ-oryzanol adsorbed on the defatted rice bran was mixed with diethyl ether / ethanol. Elution was revealed. Therefore, it was revealed that defatted rice bran specifically adsorbs relatively polar components such as plant sterols, γ oryzanol and chlorophyll without chemical modification. Using this, it is possible to concentrate these health functional substances into defatted rice bran.
　分離・溶出溶媒について検討した。食品への適用を考えると、溶媒として麻酔作用などを有するジエチルエーテルを用いると残留性の問題が残る。一方、ｎ－ヘキサンは残留性が低く、米糠油の抽出にも用いられる。また、エタノールは飲用としても使用されることから、これらの混合溶媒にて同様の効果が得られるか否かについて検討を加えた。図４（ｎ－ヘキサン・エタノール混合溶媒によるγオリザノールの分離。図中白い星印がγオリザノール）に示すように、脱脂米糠カラムに吸着したγオリザノールは、ｎ－ヘキサン・エタノール混合溶媒（１００：１，ｖ／ｖ）によって溶出された。 The separation / elution solvent was examined. Considering application to foods, if diethyl ether having an anesthetic action is used as a solvent, the problem of persistence remains. On the other hand, n-hexane has low persistence and is also used for extraction of rice bran oil. In addition, since ethanol is also used for drinking, studies were made as to whether similar effects could be obtained with these mixed solvents. As shown in FIG. 4 (Separation of γ-Oryzanol with n-Hexane / Ethanol Mixture. White Stars are γ-Oryzanol), γ-Oryzanol adsorbed on the defatted rice bran column is mixed with n-hexane / ethanol mixed solvent (100: 1, v / v).
　そこで、更に詳細な溶出パターンを明らかにした。図５（ヘキサン・エタノール混合溶媒によるγオリザノールの分離。図中白い星印がγオリザノール。）に示すように、γオリザノールは脱脂米糠カラムより、ｎ－ヘキサン・エタノール（１００：０．７）で溶出されることが明らかとなった。 Therefore, a more detailed dissolution pattern was clarified. As shown in Fig. 5 (Separation of γ-Oryzanol with a mixed solvent of hexane and ethanol. In the figure, the white star is γ-Oryzanol.) Γ-Oryzanol was removed from the defatted rice bran column with n-hexane / ethanol (100: 0.7). Elution was revealed.
　［乾燥脱脂米糠に吸着した健康機能成分の溶出・分離条件の検討］
　脱脂穀類糠によるγオリザノール吸着に及ぼすｐＨの影響について検討した。種々のｐＨに調整した１００ｍＭ　3,3-dimethylglutaric acid(ＧＴＡ)緩衝液を作製し、γオリザノール吸着済み米糠（１ｇ）を緩衝液中（５０ｍｌ）中に分散して１時間室温で攪拌した。吸引濾過にて米糠を回収し、クロロホルムメタノール混液にて全脂質を抽出した。得られた抽出液を、クロロホルムを展開溶媒としたＳｉ６０シリカゲルにて分離し、３０２ｎｍにおける蛍光強度から定量し、吸着残増量を算出した。 [Examination of elution and separation conditions for health functional ingredients adsorbed on dried defatted rice bran]
The effect of pH on γ-oryzanol adsorption by defatted cereal meal was investigated. 100 mM 3,3-dimethylglutaric acid (GTA) buffer solutions adjusted to various pH were prepared, and γ-oryzanol-adsorbed rice bran (1 g) was dispersed in the buffer solution (50 ml) and stirred at room temperature for 1 hour. The rice bran was collected by suction filtration, and the total lipid was extracted with a chloroform methanol mixed solution. The obtained extract was separated on Si60 silica gel using chloroform as a developing solvent, and quantified from the fluorescence intensity at 302 nm to calculate the residual adsorption amount.
　図６に示すようにγオリザノール吸着米糠はｐＨの上昇とともに吸着したγオリザノールを保持できなくなることが明らかとなった。これは、米糠中に含まれるリグニンのフェノール基がイオン化することによって、γオリザノールの吸着力が著しく低下することが主な原因であると考えられた。したがって、γオリザノール吸着米糠は、酸性である胃ではγオリザノールを吸着しており、中性から弱アルカリ性となる腸でγオリザノールを徐々に放出する徐放性を有することが明らかとなった。 As shown in FIG. 6, it was revealed that the γ-oryzanol-adsorbed rice bran cannot retain the adsorbed γ-oryzanol as the pH increases. The main reason for this was thought to be that the adsorbing power of γ-oryzanol was significantly reduced by ionizing the phenol group of lignin contained in rice bran. Therefore, it was clarified that γ-oryzanol-adsorbed rice bran adsorbs γ-oryzanol in the acidic stomach and has a sustained release property that gradually releases γ-oryzanol in the intestine that is neutral to weakly alkaline.
　［完全脱脂小麦フスマを用いた健康機能成分の吸着］
上記実施例１の乾燥脱脂米糠と同様の処理によって調製した完全脱脂小麦フスマ及び小麦フスマからデンプン並びにセルロースを糖化処理によって除いたバイオマス残渣について、γオリザノールの結合量を測定した。 [Adsorption of health functional ingredients using fully defatted wheat bran]
The binding amount of γ-oryzanol was measured on the completely defatted wheat bran prepared by the same treatment as the dried defatted rice bran of Example 1 and the biomass residue obtained by removing starch and cellulose from the wheat bran by saccharification treatment.
　結果、前者では０．７５±０．１２ｍｇ／ｇ 完全脱脂小麦フスマ、後者では４．２１±０．６５ｍｇ／ｇ バイオマス残渣、の結合が確認できた。 As a result, the binding of 0.75 ± 0.12 mg / g２ completely defatted wheat bran in the former and 4.21 ± 0.65 mg / g biomass residue in the latter was confirmed.
