본 발명을 구체적으로 설명하면 다음과 같다.The present invention will be described in detail as follows.
제 1 단계 (원료 준비단계)1st step (raw material preparation step)
녹차잎으로부터 유효 성분의 추출은 물이나 에탄올 등의 용매를 이용하여 통상의 방법으로 행할 수 있다. 예를 들어, 녹차잎에 부피비로 3∼5배의 용매를 가하고, 상온∼50℃정도로 유지하면서 2∼4시간 동안 교반 추출하여 추출액을 얻는다. 추출액은 여과한 후 원심 분리를 통하여 잔사를 완전히 제거한 후 감압 농축기에서 수분함량 15∼30%까지 농축한 후 진공 건조기 또는 분무 건조기에서 건조시켜 분말로 만든다. 녹차 추출물의 순도를 나타내는 폴리페놀 함량은 추출 분말 중의 80 wt% 이상인 것이 바람직하다. 폴리페놀 함량이 80 wt%보다 낮은 경우에는 폴리페놀 성분 이외의 다른 부성분들의 영향으로 유화과정이 매우 복잡해지며, 유화액의 안정성도 떨어질 뿐아니라, 최종 유화액에 첨가되는 폴리페놀의 농도가 낮아지게 되므로, 충분한 항산화효과를 얻을 수 없다.Extraction of the active ingredient from the green tea leaves can be performed by a conventional method using a solvent such as water or ethanol. For example, 3-5 times the volume of the solvent is added to the green tea leaves, and the mixture is stirred and extracted for 2 to 4 hours while maintaining the temperature at about 50 ° C to obtain an extract. The extract is filtered and then completely removed from the residue by centrifugation. The extract is concentrated to 15-30% of water in a vacuum concentrator and dried in a vacuum or spray dryer to powder. The polyphenol content indicating the purity of the green tea extract is preferably 80 wt% or more in the extract powder. If the polyphenol content is lower than 80 wt%, the emulsification process becomes very complicated due to the influence of other subcomponents other than the polyphenol component, and the stability of the emulsion is not only decreased, but also the concentration of the polyphenol added to the final emulsion is lowered. Not enough antioxidant effect is obtained.
제 2 단계 (용해단계)2nd stage (melting stage)
이상과 같이 분말로 제조된 녹차 추출물은 수용성 성분이기 때문에 이를 유지에 첨가하여 사용하는 유용성 항산화제로 사용하기 위해서는 유화과정을 거쳐 상을 변화시켜야 하며, 유화단계에 들어가기 전에 분말로 제조된 녹차추출물을 적절한 용매에 용해시켜야 한다.Since the green tea extract prepared as a powder is a water-soluble ingredient, in order to use it as an oil-soluble antioxidant used in addition to oils and fats, the phase must be changed through an emulsification process. It must be dissolved in a solvent.
용매로는 물, 에탄올, 프로필렌글리콜 또는 글리세롤 등을 사용할 수 있으나, 어느 정도의 점도를 가진 용매가 안정된 유화액을 만드는 데 효과적이므로, 프로필렌글리콜이나 글리세롤이 특히 바람직하다. 이때 녹차 추출물의 용해 농도는 최종 유화제품의 특성에 따라 다르지만 일반적으로 5 ~ 50%(w/w)까지 용해시킨다. 50% 이상의 농도에서는 점도가 급상승하기 때문에 용해시키기 어려우며, 5% 이하의 농도에서는 항산화력을 발휘하지 않는다. 분말화시킨 녹차 추출물의 가사 비중이 작기 때문에 서서히 용해시켜야 하며 이때 용해 온도는 50 ~ 60℃가 적당하다.Water, ethanol, propylene glycol or glycerol may be used as the solvent, but propylene glycol or glycerol is particularly preferable because a solvent having a certain viscosity is effective for producing a stable emulsion. At this time, the concentration of dissolution of green tea extract depends on the characteristics of the final emulsified product, but generally dissolves up to 5-50% (w / w). It is difficult to dissolve because the viscosity rises sharply at a concentration of 50% or more, and does not exhibit antioxidant power at a concentration of 5% or less. Due to the small household specific gravity of the powdered green tea extract, it should be slowly dissolved. The dissolution temperature is suitable at 50 to 60 ° C.
제 3 단계 (유화단계)Third stage (emulsification stage)
유화시 2가지 이상의 유화제를 혼합 사용하면 유화제의 지방산기가 계면에서 분자간 인력에 의해서 회합되기 때문에 안정한 유화액을 만들 수 있다. 따라서, 본 발명에서는 녹차 추출물의 안정한 유화 조성물을 제조하기 위하여, HLB 값이 각각 3.5 ~ 4.0, 3.0∼3.5, 2 이하인 유화제들을 순차적으로 가하면서 다단 유화하는 것을 특징으로 한다.When two or more emulsifiers are mixed and used in emulsification, the fatty acid groups of the emulsifier are associated with intermolecular attraction at the interface, thereby making a stable emulsion. Therefore, in the present invention, in order to prepare a stable emulsion composition of green tea extract, the HLB value is characterized in that the multi-stage emulsification while sequentially adding emulsifiers of 3.5 to 4.0, 3.0 to 3.5, 2 or less.
1) 1차 유화1) Primary oil painting
용해가 완료된 액상의 녹차 추출물에 HLB 값이 3.5 ~ 4.0 정도인 유화제, 예를들어, 올레산, 스테아르산, 베헨산 에스테르와 같은 글리세린 모노 지방산 에스테르를 첨가하여 교반한다. 수용성 성분을 유화시키기 위해서는 단계적으로 수용성 성분을 유용화시켜야 하는 데 HLB가가 더 낮은 유화제를 바로 사용할 경우 유화액의 안정성이 낮아지기 때문에 단계적으로 HLB가 높은 단계에서 낮은 단계로 사용하는 것이 바람직하다.The dissolved green tea extract is stirred by adding an emulsifier having an HLB value of 3.5 to 4.0, for example, glycerin mono fatty acid ester such as oleic acid, stearic acid, and behenic acid ester. In order to emulsify the water-soluble component, it is desirable to use the water-soluble component in stages. However, when the emulsifier having a lower HLB value is used directly, the stability of the emulsion is lowered.
유화제는 녹차 추출물 용액 100중량부에 대하여 100~150 중량부의 첨가하는 것이 바람직하다. 유화제 양이 녹차 추출물이 녹아있는 프로필렌글리콜이나 글리세롤보다 작을 경우 소정의 유화효과가 달성되지 못하고, 너무 높은 경우에는 유화에는 문제가 없지만 녹차추출물이 희석되어 원하는 항산화력을 얻지 못하게 된다. 교반 유화시 온도는 75℃를 넘지 않도록 하고 20분 이상 교반시키는 것이 바람직하다.It is preferable to add 100-150 weight part of emulsifiers with respect to 100 weight part of green tea extract solutions. If the amount of the emulsifier is smaller than propylene glycol or glycerol in which the green tea extract is dissolved, a predetermined emulsifying effect is not achieved. If the amount of the emulsifying agent is too high, there is no problem in emulsification, but the green tea extract is diluted to obtain the desired antioxidant power. The temperature during stirring emulsification is preferably not more than 75 ℃ and stirred for 20 minutes or more.
2) 2차 유화2) secondary oil painting
2차 유화에는 1차 유화에 사용한 유화제보다 HLB 값이 조금 더 낮은 유화제를 사용하는 것이 바람직하다. 특히, HLB 값이 3.0∼3.5인 유화제를 사용하는 것이 바람직하며, 예를 들면 글리세린 모노 스테아르산 에스테르, HLB가를 상기 범위로 맞춘 자당 지방산 에스테르 등을 사용할 수 있다.It is preferable to use an emulsifier with a slightly lower HLB value than the emulsifier used for the primary emulsification. In particular, it is preferable to use an emulsifier having an HLB value of 3.0 to 3.5, and for example, glycerin monostearic acid ester, sucrose fatty acid ester having HLB value in the above range, and the like can be used.
2차 유화제는 고체 상태의 유화제이므로, 과량이 첨가될 경우 안정된 유화액에서 서서히 분리되어 결정으로 석출될 우려가 있다. 따라서, 2차 유화제는 녹차 추출물 용액 100 중량부에 대해 1∼5 중량부 첨가하는 것이 바람직하며, 1차 유화 과정과 같은 방법으로 유화시킨다.Since the secondary emulsifier is an emulsifier in the solid state, there is a fear that when an excess is added, it is gradually separated from the stable emulsion and precipitated as crystals. Therefore, the secondary emulsifier is preferably added 1 to 5 parts by weight based on 100 parts by weight of the green tea extract solution, and emulsifies in the same manner as the primary emulsification process.
3) 3차 유화3) tertiary oil painting
2차 유화가 완료된 유화액에 HLB 값이 2 이하인 3차 유화제를 가하여 서서히 첨가하면서 고속 교반하여 유화과정을 완료한다. 3차 유화의 조건은 1차, 2차 유화시와 동일하게 할 수 있다.A tertiary emulsifier having a HLB value of 2 or less is added to the emulsion to which the secondary emulsification is completed. The conditions of the tertiary emulsification can be the same as in the first and second emulsification.

3차 유화제로는 폴리글리세린 폴리리시놀레이트(폴리글리세린 축합리시놀레인산 에스테르), HLB가를 상기 범위로 맞춘 자당지방산에스테르 등을 녹차 추출물 용액 100 중량부를 기준으로 120 ~ 200중량부 사용하는 것이 바람직하다. 폴리글리세린 폴리리시놀레이트는 고 점조성의 액체로 친유성이 강하기 때문에 본 발명에서와 같은 W/O 유화에 특히 적합하다.As the third emulsifier, it is preferable to use polyglycerol polyricinoleate (polyglycerin condensed ricinoleic acid ester), sucrose fatty acid ester such as HLB value in the above range, and 120 to 200 parts by weight based on 100 parts by weight of green tea extract solution. Do. Polyglycerin polyricinolate is a high viscosity liquid and is particularly suitable for W / O emulsification as in the present invention because of its high lipophilic property.
본 발명에서는 유화 단계 진행에 따라 HLB 값이 낮은 유화제를 사용하여 최종적으로 유지에 균일하게 혼합될 수 있는 안정한 W/O 형태의 에멀전을 얻을 수 있다. 얻어진 에멀젼은 당초 녹차 추출물 원료가 가지고 있던 항산화성분을 유효하게 함유하므로, 유지, 정유(essential oil) 등 유성 재료의 항산화제로서 유용하게 사용될 수 있다.In the present invention, as the emulsification step proceeds, an emulsion having a low HLB value may be used to obtain a stable W / O type emulsion which may be finally uniformly mixed with fats and oils. Since the obtained emulsion effectively contains the antioxidant component of the green tea extract raw material, it can be usefully used as an antioxidant of oily materials such as fats and oils and essential oils.
이하, 본 발명의 구체적인 실시예는 다음과 같다. 이들 실시예는 단순히 본 발명을 예시하기 위한 것으로, 본 발명이 이에 제한되지는 않는다.Hereinafter, specific embodiments of the present invention are as follows. These examples are merely to illustrate the invention, but the invention is not limited thereto.
