Description

本発明は、卵黄リゾリン脂質を高配合した油脂組成物を充填したソフトカプセル剤において、カプセル充填に適性な流動性を付与し、保存中の油分離や非油溶性成分の沈殿を抑制したソフトカプセル剤に関する。 The present invention relates to a soft capsule filled with an oil composition containing a high blend of egg yolk lysophospholipids, which imparts fluidity suitable for capsule filling and suppresses oil separation during storage and precipitation of insoluble components. .

卵黄リン脂質は、様々な生理機能を有し、その有用性を期待して多くの食品に利用されている。本出願人は卵黄リン脂質とビタミンB12とを共に摂取することにより、脳機能が改善されることを見出し、特許(特許第3073224号(特許文献1))を出願している。脳機能改善機能は、卵黄リン脂質が脳の神経伝達に深く関わるアセチルコリンの原料となるとともに、ビタミンB12がアセチルコリン合成酵素の補酵素となることにより、脳内のアセチルコリン濃度が増加することによるものと考えられている。その他、卵黄リン脂質は血清コレステロール低下作用等様々な生理機能を有している。 Egg yolk phospholipids have various physiological functions and are used in many foods in anticipation of their usefulness. The present applicant has found that brain function is improved by ingesting egg yolk phospholipid and vitamin B 12 together, and has applied for a patent (Japanese Patent No. 3073224 (Patent Document 1)). Brain function improving function, together with the egg yolk phospholipid as a raw material for the closely related acetylcholine neurotransmission in the brain, by vitamin B 12 is the coenzyme for acetylcholine synthesis enzyme, due to the fact that the acetylcholine concentration in the brain is increased It is believed that. In addition, egg yolk phospholipid has various physiological functions such as a serum cholesterol lowering action.

また、本発明者は卵黄リン脂質が酵素等によりモノアシル化された卵黄リゾリン脂質とすることにより、卵黄リン脂質の消化管からの吸収がより促進され、速やかに血中へ移行することを確認している。即ち、SD系ラットに、卵黄リン脂質あるいは卵黄リゾリン脂質を、コリン量が同等となる量を投与し、投与前及び投与後2、4、8及び24時間目の血清コリン濃度を経時的に観察した。経口投与前の血清コリン濃度と比較して卵黄リン脂質群、卵黄リゾリン脂質群ともに投与後2時間目以降に増加が見られ、卵黄リゾリン脂質群の血清コリン濃度は、投与後2時間目に最大値を示し、その後低下したのに対し、卵黄リン脂質群は4時間目に最大値を示した。投与後2時間目の卵黄リゾリン脂質群の血清コリン濃度は、卵黄リン脂質群に比べ有意に高い値を示した(p<0.01)。投与後24時間目までの血清コリンのAUC(濃度時間曲線下面積)を比較すると、卵黄リゾリン脂質群は卵黄リン脂質群に比べ高い値を示した。したがって、投与後24時間目までに血中へ到達したコリン量の合計値が高いことをラットによる動物実験で確認している。卵黄リン脂質を摂取した場合、血清コリン濃度の上昇とともに脳内アセチルコリン濃度も上昇することが確認されているため、卵黄リゾリン脂質を摂取した場合は、卵黄リン脂質を摂取する場合よりも脳機能改善効果も高まることが期待できる。 In addition, the inventor confirmed that absorption of yolk phospholipid from the digestive tract is further promoted and rapidly transferred into the blood by using egg yolk lysophospholipid monoacylated with an enzyme or the like. ing. That is, yolk phospholipids or egg yolk lysophospholipids were administered to SD rats in an amount equivalent to the amount of choline, and serum choline concentrations were observed over time before administration and at 2, 4, 8 and 24 hours after administration. did. Compared to the serum choline concentration before oral administration, both the yolk phospholipid group and the yolk lysophospholipid group showed an increase after 2 hours after administration, and the serum choline concentration in the egg yolk lysophospholipid group was highest at 2 hours after administration. The egg yolk phospholipid group showed a maximum value at 4 hours, whereas the value decreased thereafter. The serum choline concentration in the yolk lysophospholipid group 2 hours after administration was significantly higher than that in the yolk phospholipid group (p <0.01). When the AUC (area under the concentration time curve) of serum choline up to 24 hours after administration was compared, the yolk lysophospholipid group showed a higher value than the yolk phospholipid group. Therefore, it has been confirmed by animal experiments using rats that the total amount of choline reached in the blood by 24 hours after administration is high. It has been confirmed that when egg yolk phospholipid is ingested, the acetylcholine concentration in the brain increases with the increase in serum choline concentration. Therefore, when yolk lysophospholipid is ingested, brain function improves compared with ingestion of egg yolk phospholipid. The effect can also be expected to increase.

このような生体に有益な卵黄リゾリン脂質を摂取する場合、ソフトカプセルに充填する形状が最も好ましい。しかし、卵黄リン脂質の中でも、卵黄リゾリン脂質は、各種分散基材に希釈しても流動性が乏しく、工業的にソフトカプセル等に充填し、ソフトカプセル剤を製することが困難であった。また、保存中にソフトカプセル内容物の油分離や非油溶性成分の沈殿が起こり品位を損ねることが分かった。 When ingesting egg yolk lysophospholipid beneficial to such a living body, a shape filled in a soft capsule is most preferable. However, among egg yolk phospholipids, egg yolk lysophospholipid has poor fluidity even when diluted in various dispersion bases, and it has been difficult to industrially fill soft capsules and the like to produce soft capsules. In addition, it was found that the oil content of the soft capsule contents and precipitation of insoluble components occurred during storage, resulting in a loss of quality.

そこで、本出願人は、卵黄レシチンを中鎖脂肪(以下MCT)と混合することにより、流動性に富み、カプセルへの充填適性に優れ、かつ析出物の生じることのない食品用卵黄レシチン混合物を発明するに至り、特許(特許第3061777(特許文献2))を取得した。しかし、上記の理由により吸収性を向上し血中移行を促進する目的で、卵黄リン脂質をモノアシル化した卵黄リゾリン脂質を用いる際には、流動性の点において充填適性が充分でないことを確認した。特許第2821779(特許文献3)にはリゾレシチン90〜99%、中鎖脂肪酸トリグリセリド1〜10%、さらには遊離脂肪酸を5%以下含有するリゾレシチン組成物が開示されているが、ソフトカプセルへの充填に適性な流動性を得るには至っていない。また、保存中の油分離や非油溶性成分の沈殿抑制に関しての検討は一切なされていない。

Therefore, the present applicant mixed a yolk lecithin with medium-chain fat (hereinafter referred to as MCT) to obtain a yolk lecithin mixture for food that is rich in fluidity, excellent in filling ability into capsules, and free from deposits. It came to invent, and the patent (patent 3061777 (patent document 2)) was acquired. However, for the above reasons, for the purpose of improving absorbability and promoting blood transfer, when using yolk lysophospholipid monoacylated from yolk phospholipid, it was confirmed that filling ability was not sufficient in terms of fluidity. . Japanese Patent No. 2821779 (Patent Document 3) discloses a lysolecithin composition containing 90 to 99% lysolecithin, 1 to 10% medium chain fatty acid triglyceride, and further 5% or less free fatty acid. It has not reached the proper fluidity. In addition, no study has been made on oil separation during storage and suppression of precipitation of non-oil-soluble components.

In particular, egg yolk phospholipids and vitamin B 12 is preferably an improved brain function when taken simultaneously.

本発明の油脂組成物に含まれるコレステロールは、卵黄リン脂質由来のものである。近年生活習慣病に対する意識の高まりからコレステロール含有量を低減させた食品サプリメントや医薬組成物が求められていることから、コレステロール含有量を2%以下、より好ましくは1%以下に低減させた卵黄リゾリン脂質を用いることが好ましい。本発明において、卵黄リゾリン脂質を最大の60%配合すると、油脂組成物中のコレステロール含有量は1.2%となる。なお、常法によると0.1%以下にまで低減することは難しい。卵黄リゾリン脂質のコレステロール含有量を低減する方法は常法による手段を用いれば良く、卵黄液とサイクロデキストリンを混合してコレステロールを包接除去する方法(特開平8−173060号)や超臨界二酸化炭素と接触させる方法(特公昭62−51092号)等が挙げられる。例えば、卵黄をホスフォリパーゼA処理して、実質的にリン脂質を全量モノアシル化し、その後、卵黄を二酸化炭素による超臨界抽出法にてコレステロール等リン脂質以外の脂溶性成分を除去する。このように処理された卵黄よりエタノール等有機溶剤にてリン脂質を抽出し、減圧乾固することにより、卵黄リゾリン脂質含有量が80%以上、コレステロール含有量が0.1〜2%の卵黄抽出物が得られる。 Cholesterol contained in the oil and fat composition of the present invention is derived from egg yolk phospholipid. In recent years, there has been a demand for food supplements and pharmaceutical compositions with reduced cholesterol content due to increased awareness of lifestyle-related diseases, so egg yolk lysolin with cholesterol content reduced to 2% or less, more preferably 1% or less. It is preferable to use lipids. In the present invention, when the maximum 60% of egg yolk lysophospholipid is blended, the cholesterol content in the oil composition becomes 1.2%. Note that it is difficult to reduce it to 0.1% or less according to a conventional method. The method for reducing the cholesterol content of egg yolk lysophospholipids may be a conventional method. A method of mixing and removing egg yolk juice and cyclodextrin to remove cholesterol (JP-A-8-173060) or supercritical carbon dioxide. And the like (Japanese Examined Patent Publication No. 62-51092) and the like. For example, the egg yolk is treated with phospholipase A 2 to substantially monoacylate the phospholipid, and then the egg yolk is subjected to supercritical extraction with carbon dioxide to remove fat-soluble components other than phospholipids such as cholesterol. Extracting phospholipids from the egg yolk thus treated with an organic solvent such as ethanol and drying under reduced pressure to extract egg yolk having an egg yolk lysophospholipid content of 80% or more and a cholesterol content of 0.1 to 2%. A thing is obtained.

以下、本発明で用いるソフトカプセル及びその製造方法について、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 soft capsule used by this invention and its manufacturing method are demonstrated concretely based on an Example. The present invention is not limited to these.

卵黄液のホスフォリパーゼA処理を行い、実質的にリン脂質を全量モノアシル化し、これをスプレードライヤーにて噴霧乾燥を行う。得られた乾燥卵黄を二酸化炭素による超臨界抽出法にてコレステロール、トリグリセリド等を除去する。このように処理された乾燥卵黄にエタノールを加え、卵黄リゾリン脂質をエタノールに溶解させる。これを適当な方法でろ過し、卵黄リゾリン脂質溶解エタノール溶液を得る。得られた卵黄リゾリン脂質溶解エタノール溶液を乾燥することにより、卵黄リゾリン脂質含有量が90%、コレステロール含有量が1%の卵黄抽出物を得た。 The egg yolk liquid is treated with phospholipase A 2 to substantially monoacylate the entire amount of phospholipid, and this is spray-dried with a spray dryer. Cholesterol, triglyceride and the like are removed from the obtained dried egg yolk by supercritical extraction with carbon dioxide. Ethanol is added to the dried egg yolk thus treated, and egg yolk lysophospholipid is dissolved in ethanol. This is filtered by an appropriate method to obtain an egg yolk lysophospholipid-dissolved ethanol solution. The obtained egg yolk lysophospholipid-dissolved ethanol solution was dried to obtain an egg yolk extract having an egg yolk lysophospholipid content of 90% and a cholesterol content of 1%.

Note) Vitamin B 12 content was analyzed by high performance liquid chromatography, and the residual rate was determined from the analytical values before and after storage.

卵黄リゾリン脂質を60%近く配合した場合(実施例2)、やや流動性に劣ったが充填適性の許容範囲であった。遊離脂肪酸を20%配合した場合(実施例3)、やや流動性に劣ったが充填適性の許容範囲であった。実施例1のマルトデキストリンをアミロデキストリンに置き換えた場合(実施例4)、充填適性も保存安定性も良好であった。卵黄リゾリン脂質を81%配合した場合(比較例1)、適性な流動性が得られなかった。実施例1の遊離脂肪酸を同量のMCTに置き換えた場合(比較例2)、適性な流動性が得られなかった。実施例1のマルトデキストリンを遊離脂肪酸に置き換えた場合(比較例3)、充填適性は良好だったが、保存中に分離や沈殿が起きた。また、保存中に分離や沈殿が見られない場合ではビタミンB12の残存率が高く(実施例2、3、4)、保存中に分離や沈殿が見られた場合ではビタミンB12の残存率が低かった(比較例3)。 When nearly 60% of egg yolk lysophospholipid was blended (Example 2), the fluidity was slightly inferior, but it was within an acceptable range of filling suitability. When 20% of the free fatty acid was blended (Example 3), the fluidity was slightly inferior, but the tolerance for filling was acceptable. When the maltodextrin in Example 1 was replaced with amylodextrin (Example 4), both the filling suitability and the storage stability were good. When 81% of egg yolk lysophospholipid was blended (Comparative Example 1), appropriate fluidity was not obtained. When the free fatty acid of Example 1 was replaced with the same amount of MCT (Comparative Example 2), appropriate fluidity was not obtained. When the maltodextrin of Example 1 was replaced with a free fatty acid (Comparative Example 3), the filling suitability was good, but separation and precipitation occurred during storage. Further, when no separation or precipitation is observed during storage, the residual rate of vitamin B 12 is high (Examples 2, 3, and 4), and when separation or precipitation is observed during storage, the residual rate of vitamin B 12 Was low (Comparative Example 3).

[Test Example 2]
In order to investigate the influence of the blending amount of dextrin on filling suitability and storage stability, Examples 5, 6, 7 and Comparative Example 4 were prepared by mixing the components in the blending table of Table 3 according to the method of Example 1. 5, an oil and fat composition having an egg yolk lysophospholipid content of 36% and a cholesterol content of 0.4% was prepared. This was filled into OVAL type soft capsules at 300 mg ± 10 mg / grain using a capsule molding machine to prepare soft capsules.

デキストリンを0.1%配合した場合(実施例5)、保存中にやや油分離が見られたが製品としての許容範囲であった。デキストリンを5.0%配合した場合(実施例7)、やや流動性に劣ったが充填適性の許容範囲であった。デキストリン配合量が0.1%未満の場合(比較例4)、保存中に油分離や非油溶性成分の沈殿が見られた。デキストリン配合量が5.0%より多い場合(比較例5)、
流動性がなく充填不能であった。また、保存中に分離や沈殿が見られない場合ではビタミンB12の残存率が高く(実施例5、6、7)、保存中に分離や沈殿が見られた場合ではビタミンB12の残存率が低かった(比較例4)。
When 0.1% of dextrin was blended (Example 5), some oil separation was observed during storage, but this was an acceptable range as a product. When 5.0% of dextrin was blended (Example 7), the fluidity was somewhat inferior, but the filling suitability was acceptable. When the dextrin content was less than 0.1% (Comparative Example 4), oil separation and precipitation of non-oil soluble components were observed during storage. When the amount of dextrin is more than 5.0% (Comparative Example 5),
It was not fluid and could not be filled. Further, when no separation or precipitation was observed during storage, the residual rate of vitamin B 12 was high (Examples 5, 6, and 7), and when separation or precipitation was observed during storage, the residual rate of vitamin B 12 was observed. Was low (Comparative Example 4).
