본 발명은 홍삼 추출시에 발생되는 사포닌의 가수분해를 일으키는 요인을 제어하여 홍삼 농축액의 사포닌 함량을 증대시키는 방법에 관한 것으로, 특히 홍삼 농축액 제조공정 중 홍삼으로부터 사포닌을 효율적으로 추출하는 방법에 관한 것이다.The present invention relates to a method for increasing the saponin content of red ginseng concentrate by controlling the factors causing hydrolysis of saponin generated during red ginseng extraction, and more particularly, a method for efficiently extracting saponin from red ginseng during the manufacturing process of red ginseng concentrate. .

인삼은 식물 분류학상으로 오갈피나무과(Araliaceae)의 인삼속(Panax)에 속하는 다년생 음지성 초본식물로서 오래전부터 한방에서 중요한 약재로 사용되어져 왔다. 인삼은 일반적으로 가공방법에 따라 백삼과 홍삼으로 구별되어지며 백삼은 밭에서 채굴한 가공되지 아니한 인삼 즉, 수삼을 그대로 건조한 것이고 홍삼은 수삼을 증숙하여 건조 가공한 것으로 제조과정 중에서 사포닌 변형과 아미노산 변화 그리고 갈변화 등의 여러 화학적인 변화가 수반된다. 특히 홍삼의 제조과정에서 발생되는 열에 의해 인삼에는 존재하지 않는 홍삼만의 특유 성분인 ginsenoside Rg2, Rg3, Rhl, Rh2 등의 사포닌 성분이 새로이 생성되며, 이러한 홍삼 특유 사포닌은 암예방 작용, 암세포 성장억제 작용, 혈압 강하작용, 뇌신경세포 보호 및 학습능력 개선작용, 항혈전 작용, 항산화 작용 등이 있다고 알려져 있어 이에 대한 홍삼만의 탁월한 약리 효능을 기대할 수 있다(J Ginseng Res 25: 107-111, J Ginseng Res 23: 81-87, Am J Chin Med 15: 19-29). 하지만 홍삼은 건조되어 딱딱하게 경질화된 상태로써 이것을 직접 섭취하기는 어렵기 때문에 일반적으로 홍삼을 섭취하기 위해서는 물로 추출해서 복용하게 되는데, 최근 들어서는 음용 및 보관이 편리한 농축액 형태로 섭취하는 것이 선호되고 있다. 따라서 국내 홍삼가공제품 대다수는 이 홍삼 농축액을 함유하거나 그 자체로서 제품화되어 시중에 판매되고 있으며, 생산현장에서도 홍삼 농축액 제조가 가장 많이 이루어지고 있다.Ginseng is a perennial herbaceous herbaceous plant belonging to the Panax of the Araliaceae in terms of plant taxonomy, and has been used as an important medicinal herb for a long time. Ginseng is generally classified into white ginseng and red ginseng according to processing method. White ginseng is dried raw ginseng mined from the field, that is, dried ginseng, and red ginseng is steamed and dried to process saponin. And several chemical changes, such as brown change. In particular, due to the heat generated during the manufacturing process of red ginseng, saponin components such as ginsenoside Rg 2 , Rg 3 , Rh l , and Rh 2 , which are not unique to ginseng, are newly generated. It is known that cancer cell growth inhibitory effect, blood pressure lowering effect, brain nerve cell protection and learning ability improvement effect, antithrombotic action, and antioxidant action can be expected to have excellent pharmacological efficacy of red ginseng ( J Ginseng Res 25: 107-). 111, J Ginseng Res 23: 81-87, Am J Chin Med 15: 19-29). However, red ginseng is dried and hardened, so it is difficult to take it directly. Generally, red ginseng is extracted with water to be consumed. In recent years, red ginseng is preferred to be consumed as a concentrated liquid for convenient drinking and storage. . Therefore, most of the red ginseng processed products in Korea contain or are commercialized as red ginseng concentrates and are sold on the market.

홍삼 농축액의 제조방법에 있어 국내 식품 공전상에는 "물이나 주정 또는 물과 주정을 혼합한 용매로 추출, 여과하여 그대로 농축한 것을 말한다"로 규정되어 있다. 따라서 일반적으로 생산현장에서의 홍삼 농축액 제조방법은 크게 추출공정, 여과공정, 농축공정 순으로 이루어지고 있으나, 아직까지 정례화된 공정이 확립되어 있지 않고, 특히 홍삼 추출공정의 경우에는 생산자마다 추출방법이 달라 똑같은 품질의 홍삼원료를 사용하는 경우에도 생산된 홍삼 농축액의 품질에 차이가 발생하고 있다. 또한 홍삼을 추출하는 방법에서 추출용매와 추출온도 및 시간을 어떻게 설정하느냐에 따라 홍삼 농축액의 품질 척도인 사포닌 함량이 달라지게 되는데(J Korean Soc Food Sci Nutr 37(2): 256-260, Korean J Food Sci Technol 17(3):227-231) 반해, 생산현장에서는 이에 대한 정확한 과학적 근거없이 대부분 오랜 경험적인 방식에 따라 홍삼을 추출하고 있는 실정이다. 기존의 홍삼 농축액 제조방법에 대한 기술로는 특허 제0416782호, 특허 제0355521호 등이 있으나 주로 홍삼의 추출 방법이 아닌 홍삼원료에 대한 기술에 집중되어 있고 추출방법에 대한 기술로 특허 제0517128호가 있지만 실제 생산현장에 적용하기 어려운 유독한 유기용매를 사용하는 공정기술이라는 한계가 있어 최근 홍삼 농축액 제형의 제품에 대한 소구가 증가하고 있는 시점에서 국내 식품법상에 부합하면서도 효율적으로 홍삼을 추출할 수 있는 방법을 개발할 필요성이 제기되고 있다.In the manufacturing method of the red ginseng concentrate, it is defined in the domestic food industry as "concentrated as it is extracted with water, alcohol or a solvent mixed with water and alcohol, filtered." Therefore, in general, the manufacturing method of red ginseng concentrate at the production site is mainly composed of extraction process, filtration process, and concentration process.However, no regular process has been established. Differences occur in the quality of red ginseng concentrates produced even when the same quality red ginseng raw materials are used. In addition, saponin content, which is a quality measure of red ginseng concentrate, varies depending on how the extraction solvent, extraction temperature, and time are set in the method of extracting red ginseng ( J Korean Soc Food Sci Nutr 37 (2): 256-260, Korean J Food Sci Technol 17 (3): 227-231) On the other hand, most ginseng extracts are produced at the production site in the long-term experience without precise scientific basis. Conventional techniques for manufacturing red ginseng concentrates include Patent No. 0416782 and Patent No. 0355521, but mainly concentrates on red ginseng raw materials, not red ginseng extraction methods, and Patent No. 0517128 as a technology for extraction methods. Due to the limitation of process technology using toxic organic solvents that are difficult to apply to actual production sites, it is possible to extract red ginseng efficiently and efficiently in accordance with the Korean Food Act when the demand for products of red ginseng concentrate formulation is increasing. There is a need to develop a framework.

홍삼을 추출하는 과정에서 홍삼의 사포닌 성분을 분해시키는 물리적 요인으로는 추출온도와 추출시간이 있으며, 화학적인 요인으로는 홍삼 추출액 상에 존재하는 유기산이 있는데 이중 하나의 요인만 변화되어도 사포닌의 분해율은 크게 변화된다(J Ginseng Res 22(3): 205-210). 홍삼 농축액의 제조과정에서 사포닌함량에 가장 큰 영향을 미치는 공정은 추출공정으로 일반적으로 물을 추출 용매로 하고 가온추출하는 전래적인 물 추출법이 생산현장에 가장 널리 애용되고 있다. 그러나 홍삼을 장시간 수용매에서 고온 처리하게 되면 추출과정에서 홍삼 자체에 함유되어 있는 유기산들의 영향으로 홍삼의 유효성분인 사포닌 분해가 심하게 일어나는 단점이 있다. 생산현장에서의 일반적인 추출조건은 대게 85∼90℃에서 24∼48시간 동안 고온추출하는 것으로 확인되고 있다. 따라서 이러한 단점을 줄이고자 최근에는 물 추출에서 전분 추출을 줄이고 사포닌 분해를 억제하기 위하여 에탄올을 이용하여 가온추출하는 방법이 사용되고 있으나, 이러한 에탄올을 용매로 추출하는 경우에는 물 추출에 비하여 수율이 낮고 흙냄새 등 이취미가 강하며 홍삼 고유의 향미가 약화되는 문제가 있다.In the process of extracting red ginseng, the physical factors that decompose the saponin component of red ginseng are extraction temperature and extraction time, and chemical factors include organic acid in red ginseng extract. Greatly changed ( J Ginseng Res 22 (3): 205-210). In the manufacturing process of red ginseng concentrate, the most influential process for saponin content is the extraction process. Conventional water extraction method using water as the extraction solvent and warm extraction is most widely used in the production site. However, if red ginseng is heated at a high temperature in a solvent for a long time, the decomposition of saponin, an active ingredient of red ginseng, is severely affected by the organic acids contained in the red ginseng itself during the extraction process. The general extraction conditions at the production site are usually confirmed by high temperature extraction for 24 to 48 hours at 85 ~ 90 ℃. Therefore, in order to reduce these disadvantages, in order to reduce starch extraction in water extraction and to suppress saponin decomposition, a warm extraction method using ethanol has been recently used. There is a problem that the smell and smell is strong and the flavor of red ginseng is weakened.

이에 본 발명자들은 홍삼 농축액을 제조할 때 추출과정에서 발생되는 사포닌 가수분해 요인을 차단시켜 사포닌을 고함유한 홍삼 농축액을 제조할 수 있는 추출기술 개발에 초점을 맞춰 연구를 진행하여 추출온도와 추출시간에 대한 추출 최적화 조건을 확립하고 중화제 첨가를 통한 유기산 중화를 통해 기존 추출법에 비해 사포닌이 고함유된 홍삼 농축액의 제조가 가능함을 확인하고 본 발명을 완성하게 되었다.Therefore, the present inventors focused on the development of extraction technology for producing red ginseng concentrate containing saponin by blocking the saponin hydrolysis factor generated during the extraction process when preparing the red ginseng concentrate at extraction temperature and extraction time. By establishing the optimization conditions for the extraction and neutralizing the organic acid through the addition of a neutralizing agent, it was confirmed that it is possible to prepare a red ginseng concentrate containing saponin higher than the conventional extraction method and completed the present invention.

따라서, 본 발명은 홍삼 농축액의 제조과정 중에서 홍삼 추출시 발생되는 사포닌 가수분해를 최소화하기 위해 추출온도와 시간에 대한 추출조건을 최적화하고 유기산 중화를 위한 중화제를 첨가하는 추출방법을 통하여 사포닌을 고함유하는 홍삼 농축액을 제공하는 것을 목적으로 한다.Therefore, the present invention optimizes the extraction conditions for extraction temperature and time and minimizes saponin hydrolysis during red ginseng extraction during the preparation of red ginseng concentrate, and contains saponin high through the extraction method of adding neutralizing agent for neutralizing organic acid. It is an object to provide a red ginseng concentrate.

본 발명에 따른 사포닌을 고함유하는 홍삼 농축액을 제조하기 위한 추출기술의 핵심은 사포닌 가수분해를 일으키는 물리적·화학적 요인을 차단시킴으로써 홍삼 농축액의 사포닌 함량을 증대시키는 것으로서 도 1에 고사포닌을 함유하는 홍삼 농축액의 제조공정을 개략적으로 도시해 두었다.The core of the extraction technique for producing a saponin-containing red ginseng concentrate according to the present invention is to increase the saponin content of the red ginseng concentrate by blocking the physical and chemical factors causing saponin hydrolysis. The manufacturing process of the concentrate is schematically shown.

본 발명에 따른 홍삼 농축액 제조공정을 보다 상세하게 설명하면 원료배합 ①단계에서는 원료인 홍삼근과 홍미삼을 배합하는 단계로써 일반적으로 홍삼근은 단맛이 강한 반면, 홍미삼은 쓴맛이 강하기 때문에 홍삼근 비율이 높을수록 관능이 우수한 홍삼 농축액을 얻을 수 있다 하지만 홍삼근 자체는 사포닌 함량이 홍미삼에 비해 적기 때문에 홍삼 농축액의 사포닌 함량을 높이기 위해서는 이들 비율을 적당량 조절할 필요가 있다. 일반적으로는 홍삼근과 홍미삼을 7:3의 비율로 배합하여 사용하지만 사포닌 함량을 높이기 위해서는 홍삼근과 홍미삼을 5:5 비율로 배합하는 것이 바람직하며, 이 경우에도 관능에는 변화가 거의 없는 것으로 확인되었다. 용제가수 ②단계는 홍삼으로부터 사포닌 등 여러 유용성분을 추출해 내기 위한 용제를 가하는 것으로서 이 때 사용되는 용제는 물과 식품용 에탄올을 혼합하여 사용하는 것이 바람직하며, 가수 비율은 원료 대비 8∼10 배수사이, 물과 에탄올 혼합비율은 에탄올 용매추출에 의한 향미 감소를 고려해 30%이내로 제한적으로 사용하는 것이 바람직하다. 중화제 첨가 ③단계는 홍삼 추출에서 홍삼 추출액 상의 유기산에 의한 사포닌 가수분해를 억제하기 위해 유기산을 중화시키는 위한 것으로서 본 발명에서는 식품첨가물로 사용이 가능한 식소다를 중화제로 사용하였고, 그 투입량은 홍삼 추출액 상의 유기산 함량 대비 중화 당량으로 환산하여 사용하였다. 추출 ④단계에서는 상기 단계에서 5:5 비율로 배합한 홍삼원료로부터 30% 에탄올을 용매로 이용하여 사포닌 등의 유효성분을 추출하는 단계로서 가온처리에 의한 사포닌의 가수분해를 억제시키기 위한 추출 최적화 조건으로 추출온도는 80℃ 추출시간은 10시간 내외로 여러 단계의 홍삼 추출조건 중에서 사포닌 함량이 가장 높은 것으로 확인되었다. 회수 및 반복 추출 ⑤단계에서는 상기 추출 단계에서 제조된 홍삼 추출액을 회수하고 동량의 30% 에탄올을 재가수하여 반복 추출하는 단계로서 반복 추출 횟수는 생산 공정 비용을 고려하여 3∼4회 추출하는 것이 바람직한 것으 로 판단된다. 여과 ⑥단계는 상기 ⑤단계에서 회수된 홍삼 추출액을 여과기에 통과시켜 침전물 및 이물질을 제거하는 단계이다. 농축 ⑦단계는 상기 ⑥단계에서 침전물 및 이물질을 여과시킨 홍삼 추출액을 농축기를 이용하여 농축하는 단계로서 이 때 농축온도로는 60℃내외로 설정하는 것이 바람직한데 이는 농축과정 중 고온가열에 의한 사포닌의 가수분해를 억제하고 홍삼 농축액의 사포닌 함량을 높은 수준으로 유지하기 위한 것이며, 이와 함께 홍삼을 추출하기 위해 사용된 에탄올을 제거하고자 하는 목적도 있다.The red ginseng concentrate manufacturing process according to the present invention will be described in more detail. In the step of raw material mixing ①, red ginseng root and red rice ginseng are used as raw materials. This excellent red ginseng concentrate can be obtained, but the red ginseng root itself has less saponin content than red ginseng, so in order to increase the saponin content of the red ginseng concentrate, it is necessary to appropriately adjust these ratios. In general, red ginseng root and red rice ginseng are used in a ratio of 7: 3, but in order to increase the saponin content, it is preferable to combine red ginseng root and red rice ginseng in a 5: 5 ratio. Solvent Singer ② is to add a solvent to extract various useful components such as saponin from red ginseng. The solvent used at this time is preferably used by mixing water and ethanol for food. , The water and ethanol mixing ratio is preferably limited to within 30% in consideration of the flavor reduction by ethanol solvent extraction. Neutralizing agent added step (3) is to neutralize the organic acid in order to suppress the saponin hydrolysis by the organic acid on the red ginseng extract in the red ginseng extract in the present invention was used as a neutralizing agent soda, which is used as a food additive, the amount of the red ginseng extract phase It was used in terms of neutralization equivalent to organic acid content. Extraction step ④ extracts an active ingredient such as saponin using 30% ethanol as a solvent from the red ginseng raw material blended at a ratio of 5: 5 in the above step, and extraction optimization conditions for inhibiting the hydrolysis of saponin by heating treatment. As the extraction temperature was 80 ℃, the extraction time was about 10 hours, and it was confirmed that the saponin content was the highest among the red ginseng extraction conditions at various stages. Recovery and repeated extraction In step ⑤, the red ginseng extract prepared in the extraction step is recovered and re-extracted by rehydrating the same amount of 30% ethanol. The number of repeated extraction is preferably extracted 3 to 4 times in consideration of the production process cost. It is judged to be. Filtration step ⑥ is a step of removing the precipitate and foreign matter by passing the red ginseng extract recovered in step ⑤ through the filter. Concentration step ⑦ is a step of concentrating the red ginseng extract from the precipitate and the foreign matter filtered in step ⑥ using a concentrator. At this time, it is preferable to set the condensation temperature to about 60 ° C. In order to suppress the hydrolysis and to maintain the saponin content of the red ginseng concentrate at a high level, there is also an object to remove the ethanol used to extract the red ginseng.

본 발명에 의한 홍삼 농축액의 사포닌 함량을 증대시키는 방법은 홍삼 추출공정에서 발생되는 사포닌의 가수분해를 일으키는 요인을 제어하여 최종적으로 홍삼 농축액의 사포닌 함량을 증대시키는 것으로 종래의 경험적인 추출방법에 의해 제조된 홍삼 농축액에 비해 월등히 높은 사포닌을 함유한 홍삼 농축액을 생산할 수 있는 효과가 있다.Method for increasing the saponin content of the red ginseng concentrate according to the present invention is to control the factor causing the hydrolysis of the saponin generated in the red ginseng extract step to finally increase the saponin content of the red ginseng concentrate prepared by the conventional empirical extraction method Compared to the red ginseng concentrate, it is effective to produce a red ginseng concentrate containing saponin.

본 발명의 추출방법의 우수성을 실제 실험을 통하여 검증하였으며, 이하 실시예를 통하여 본 발명을 보다 상세히 설명하고자 하나, 다음의 실시예는 본 발명을 보다 쉽게 이해하기 위해 제공되는 것으로 본 발명이 이들 실시예, 비교예에 의해 한정되는 것은 아니다.Although the excellence of the extraction method of the present invention was verified through actual experiments, the present invention will be described in more detail through the following examples, but the following examples are provided to more easily understand the present invention.
