Description
본 발명은 표고버섯으로부터 베타-글루칸(β-glucan)을 추출하는 방법에 관한 것으로, 더욱 상세하게는, 열수 추출 및 초고압 추출을 순차적으로 병행하여 표고버섯으로부터 베타-글루칸을 고수율로 추출할 수 있는 방법에 관한 것이다.
The present invention relates to a method for extracting beta-glucan from shiitake mushroom, and more particularly, to a method for extracting beta-glucan from shiitake mushroom in succession in parallel with hot water extraction and ultra high pressure extraction How to do it.
베타-글루칸(β-glucan)은 다시마 등의 조류, 버섯, 효모 및 곡물 등에 있는 다당류 일종으로 세포막을 구성하는 성분이다. 베타-글루칸은 포도당 중합체인데, 포도당의 1, 3 위치에 β-글리코시드 결합을 기본 구조로 가지며, 이 외에 포도당이 결합되는 위치에 따라 β-1,4 또는 β-1,6의 구조를 가질 수 있다.Beta-glucan is a kind of polysaccharide found in algae, mushroom, yeast, and grains such as sea tangle, and constitutes a cell membrane. Beta-glucan is a glucose polymer, which has a basic structure of β-glycoside bonds at 1 and 3 positions of glucose, and has a structure of β-1,4 or β-1,6 depending on the position where glucose is bonded .
베타-글루칸은 β-1,3 결합, β-1,4 결합, β-1,6 결합 등 포도당 결합 위치 또는 분지 위치에 따라 종류가 다양한데, 기원에 따라서도 분지도, 용해도, 3차 구조 등에 많은 차이가 있어, 물리화학적 특성 및 생체기능이 다양한 것으로 알려져 있다 (E. Sonck et al., Veterinary Immunology and Immunopathology 135:199-207, 2010). 예를 들어, 다시마 유래의 베타-글루칸은 β-1,3 결합 및 β-1,6 결합(30:1)을 가지며 분자량이 약 7.7 kDa 이고, 표고버섯(Lentinus edodes)의 베타-글루칸은 β-1,3 주당쇄의 매 5개의 잔기 내에 2개씩 β-1,6-잔기를 갖는 β-1,6-분지-β-1,3-글루칸이며, 효모(Saccharomyces cerevisiae)의 베타-글루칸은 세포벽에서 추출되며, 분지가 거의 없고 불균일하며 불용성인 특징이 있다.Beta-glucan has various types depending on the position of glucose bonding or branching position such as β-1,3 bond, β-1,4 bond, β-1,6 bond, etc. Depending on the origin, degree of branching, solubility, tertiary structure It is known that there are many differences in physico-chemical properties and biological functions (E. Sonck et al., Veterinary Immunology and Immunopathology 135: 199-207, 2010). For example, beta-glucan derived from kelp has a beta-1,3 bond and a beta-1,6 bond (30: 1) and has a molecular weight of about 7.7 kDa, and mushroom ( Lentinus beta edodes) - glucan is a β-1,6- branched -β-1,3- glucan, with a two by two residues in the β-1,6- every five residues of the β-1,3 week sugar, yeast ( Saccharomyces The β-glucan of S. cerevisiae is extracted from the cell wall and has little branching, heterogeneity and insolubility.
베타-글루칸은 면역력을 증가시키고 세포의 활성을 증가시키는 물질로 알려져 있는데, 최근의 연구 보고에 의하면, 항암 효과, 항당뇨 효과, 항고지혈증 효과, 항비만 효과 등이 있는 것으로 알려져 있다.Beta-glucan is known as a substance that increases immunity and increases the activity of cells. According to recent research reports, it is known that there is anticancer effect, antidiabetic effect, antihyperlipidemic effect and anti-obesity effect.
한편, 표고버섯(Lentinula edodes)은 담자균류 주름버섯목 느타리과에 속하는 버섯으로서, 영양기관인 균사체와 번식기관인 포자를 지닌 자실체로 되어 있고, 뒷면이 하얗고, 깨끗한 주름이 있으며, 특별한 향미와 감칠맛이 있어 예로부터 식용으로 널리 이용된 버섯이다.Meanwhile, shiitake mushrooms ( Lentinula edodes ) is a mushroom belonging to the family Aspergillus spp., which is a fruiting body with mycelium and reproductive organs as reproductive organs. It has white back, clean wrinkles, and has a special flavor and rich taste. It is mushroom.
표고버섯에는 단백질, 지방, 탄수화물뿐만 아니라 칼슘, 칼륨, 인, 셀레늄,철분 등의 미네랄, B1, B2 등의 비타민, 식이섬유가 풍부하게 함유되어 있다. 또한, 프로비타민 D(provitamin D)인 에르고스테롤(ergosterol), 혈압 강하와 당뇨병에 효과적인 에리타데닌(erithadenine), 탄수화물ㆍ지방ㆍ단백질 대사 및 세포호흡과 당 분해작용에 관여하는 나이아신(niacin) 등 생리활성물질이 있어 식용 외에 약재로도 이용되었다.Shiitake mushrooms contain not only proteins, fats and carbohydrates, but also minerals such as calcium, potassium, phosphorus, selenium and iron, vitamins such as B1 and B2, and dietary fiber. It is also known that ergosterol, which is provitamin D, erithadenine, which is effective for blood pressure lowering and diabetes, carbohydrate, fat and protein metabolism, and niacin, which is involved in cell respiration and glucose degradation It was also used as a medicinal material in addition to edible because of its physiologically active substance.
한편, 표고버섯에는 베타-글루칸이 많이 함유되어 있는 것으로 알려져 있는데, 표고버섯으로부터 베타-글루칸을 추출하고자 하는 노력들이 종래에 많이 이루어져 왔다. 하지만, 대부분 단순 가압 열수 추출에 의존하고 있어, 추출 수율이 그다지 높지 않은 실정이다. On the other hand, shiitake has been known to contain a large amount of beta-glucan. Efforts to extract beta-glucan from shiitake have been made in the past. However, most of them depend on the simple pressurized hot water extraction, and the extraction yield is not so high.
따라서, 표고버섯으로부터 베타-글루칸을 고수율로 추출할 수 있는 새로운 기술을 개발할 필요가 있다.
Therefore, it is necessary to develop a new technique for extracting beta-glucan from shiitake at a high yield.
본 발명에서는 표고버섯으로부터 베타-글루칸을 고수율로 생산할 수 있는 새로운 추출 방법을 개발하여 제공하고자 한다.
In the present invention, a new extraction method capable of producing beta-glucan at a high yield from shiitake is developed and provided.

According to the method of the present invention, beta-glucan, especially beta-glucan having beta-1, 6-branch beta-1,3 bond, It can be produced at a yield of 30%. Specifically, beta-glucan having beta-1, 6-branching beta-1,3 linkages is extracted with 9.17% in the case of simple pressurized hot water extraction and 9.73% in the case of simple hyperbaric extraction. In the case of the "hot pressurized hydrothermal extraction → ultra-high pressure extraction" of the invention, the content was extracted at a content of 13.15%. At this time, in case of 'Extra-high pressure extraction → Pressurized hot water extraction' in which the order of pressurized hot water extraction and ultra high pressure extraction was changed, the content was extracted to 10.97%.
한편, 본 발명의 표고버섯으로부터 베타-글루칸을 추출하는 방법은, 단계(b) 후, 동결건조하는 단계(c)를 추가로 포함할 수 있다. 동결건조는 당업계에 널리 알려진 방법을 어느 것이나 사용하여도 무방하다. On the other hand, the method for extracting beta-glucan from the shiitake of the present invention may further include a step (c) of lyophilizing after step (b). The lyophilization may be carried out by any method well known in the art.
한편, 본 발명의 표고버섯으로부터 베타-글루칸을 추출하는 방법에 있어서,상기 표고버섯은, 일 예로 건(乾) 표고버섯인 것일 수 있다. On the other hand, in the method for extracting beta-glucan from the shiitake mushroom of the present invention, the shiitake may be, for example, dried shiitake.

Meanwhile, in the method of extracting beta-glucan from the shiitake mushroom of the present invention, the beta-glucan may be preferably beta-glucan having beta-1, 6-branch beta-1,3 bonds. According to the present invention, the extraction yield of beta-glucan having β-1, 6-branching β-1, 6-branching was particularly high among the β-glucans.
본 발명의 열수 추출 및 초고압 추출의 순차적 병행 추출방법에 의할 경우, 단순 열수 추출 또는 단순 초고압 추출에 비해 β-1,6 분지 β-1,3 결합을 갖는 베타-글루칸의 추출 수율이 약 20~30% 정도 향상됨을 확인할 수 있었다.
According to the sequential simultaneous extraction method of hot water extraction and ultra-high pressure extraction according to the present invention, the extraction yield of beta-glucan having β-1,6-branching β-1,3 bond is about 20 ~ 30%.
