Description
본 발명은 버섯으로부터 식이 섬유를 농축하여 분리하는 방법에 관한 것으로, 더욱 상세하게는 초산발효를 통해 버섯으로부터 식이 섬유를 농축하여 분리하는 방법에 관한 것이다.The present invention relates to a method for concentrating and separating dietary fiber from mushrooms, and more particularly, to a method for concentrating and separating dietary fiber from mushrooms through acetic acid fermentation.
버섯은 일종의 곰팡이로서 고등균류에 속하며 균류(菌類) 중에서 눈으로 식별할 수 있는 크기의 자실체(子實體)를 형성하는 무리를 총칭한다. Mushroom is a kind of fungus, belongs to higher fungi, and refers to a group of fungi that form fruiting bodies of a size discernible to the eye.
버섯은 영양기관인 균사체와 포자를 지닌 자실체로 구성되어 있으며, 균사체에는 자실체보다 4배 정도 많은 각종 영양소와 자실체에 비해 50~60배 정도 많은 항암성분과 면역기능강화 성분 등의 약용성분이 함유되어 있다. 자실체는 갓 모양으로 버섯의 전부라고 생각하기 쉬우나 일반식물의 꽃에 해당되는 부분이며 극히 짧은 기간에 발생한다.Mushrooms are composed of mycelia and spores with nutritional organs, and mycelium contains four times as many nutrients as fruiting bodies and medicinal ingredients such as anti-cancer ingredients and immune-enhancing ingredients compared to fruiting bodies. . Fruiting bodies are freshly shaped and are considered to be all of mushrooms, but they correspond to flowers of general plants and occur in a very short period of time.
버섯의 주성분은 수분 80-90%, 단백질 7-8%, 지질 1%, 무기질 1%정도 이고, 비타민 B2와 에르고스테린이 풍부하다. 또한 버섯의 독특한 맛을 내는 구아닐산이 함유된 식물로서 고혈압, 심장병, 동맥경화 예방에 효과가 있으며 항암 효과가 있는 것으로 밝혀져 있다. 특히 버섯에 함유된 다당류 성분 중 베타글루칸(β-glucan)은 정상적인 세포조직의 면역기능을 활성화시켜 암세포의 증식 및 재발을 방지한다.The main components of the mushroom are 80-90% moisture, 7-8% protein, 1% lipid, 1% minerals, and are rich in vitamin B 2 and ergosterine. In addition, it is a plant containing guanilic acid, which gives a unique taste of mushrooms, and is effective in preventing hypertension, heart disease, and atherosclerosis, and has been shown to have an anticancer effect. In particular, beta glucan (β-glucan) of the polysaccharides contained in the mushrooms to prevent the proliferation and recurrence of cancer cells by activating the immune function of normal tissues.
한편, 식이섬유는 사람의 소화 효소로는 소화되지 않는 식물 중의 난소화성 성분의 총체로서 고분자 탄수화물을 말하며, 채소, 과일, 해조류 등의 식품에 과량 함유되어 있는 섬유질 또는 셀룰로오스로 알려진 성분이다.On the other hand, dietary fiber refers to polymer carbohydrates as a total of indigestible components in plants which are not digested by human digestive enzymes, and are known as fiber or cellulose contained in excess in foods such as vegetables, fruits and seaweeds.
식이섬유는 특유의 보수성과 팽윤성으로 장내의 수분을 흡수하여 팽창시킴으로써 변비를 없애고, 포만감은 주지만 소화되지 않고 바로 배설되기 때문에 음식 섭취를 적게 하여 비만증 예방, 체중 감량 등에 효과를 발휘한다. 또한 독성물질, 콜레스테롤 등 인체에 해로운 물질을 몸 밖으로 배출시키기도 하여 관상동맥경화증, 협심증, 심근경색증 등의 질환을 예방하고, 혈압이 올라가는 것을 막아 주기 때문에 당뇨병의 치료와 예방에 도움을 주는 효과를 발휘하기도 한다. Dietary fiber eliminates constipation by absorbing and swelling water in the intestine with its unique conservativeness and swelling, and gives a feeling of satiety, but it is directly excreted without digestion. It also releases harmful substances such as toxic substances and cholesterol out of the body to prevent diseases such as coronary atherosclerosis, angina pectoris, myocardial infarction, and prevent blood pressure from rising, thus helping to treat and prevent diabetes. Sometimes.
이에 식이섬유를 분리하여 식품의 소재로 사용하기 위한 노력이 종래에 많이 있어 왔는데, 이와 관련된 특허기술로는 미강으로부터 식이섬유를 분리하는 방법(대한민국 특허등록 10-0614153)이 있다. Thus, there have been many efforts to separate the dietary fiber and use it as a material for food, and the related patented technology is a method for separating the dietary fiber from rice bran (Korean Patent Registration 10-0614153).
하지만, 상기 분리법은 미강으로부터 식이섬유를 분리하는 것에 관한 것일 뿐, 버섯으로부터 식이섬유를 농축하여 분리하는 방법에 대해서는 종래에 알려진 바가 없었다.However, the separation method only relates to separating the dietary fiber from the rice bran, and there is no known method of concentrating and separating the dietary fiber from the mushroom.
이에 본 발명은 버섯으로부터 식이섬유를 농축하여 분리하는 방법을 제공하는데 그 목적이 있다.Accordingly, an object of the present invention is to provide a method for concentrating and separating dietary fiber from mushrooms.
상기 목적을 달성하기 위하여 본 발명은, 버섯을 초산발효시키는 단계; 발효 후, 발효액을 제거하고 잔사를 회수하는 단계; 회수한 잔사물을 물로 반복 세척하는 단계; 세척한 잔사물을 건조시키는 단계; 및, 건조한 잔사물을 분쇄하는 단계를 포함하는 것을 특징으로 하는 버섯으로부터 식이섬유를 농축하여 분리하는 방법을 제공한다.The present invention to achieve the above object, the step of acetic acid fermenting mushrooms; After fermentation, removing the fermentation broth and recovering the residue; Repeatedly washing the collected residue with water; Drying the washed residue; And, it provides a method for concentrating and separating the dietary fiber from the mushroom, characterized in that it comprises the step of crushing the dry residue.
일반적으로 '특정 성분의 농축 및 분리'라 함은 베이스(최종 산물을 분말형태로 얻을 경우는 고형분을 의미함) 중 해당 성분의 함량을 증대시키는 것을 의미하나, 역으로 목적 성분 외의 성분들을 제거시킴으로써 농축하는 것을 의미하기도 한다. 본 발명은 이 중 후자의 방법에 의한 농축 및 분리 방법에 관한 것이다. 즉, 본 발명의 버섯으로부터 식이섬유를 농축하여 분리하는 방법은 버섯 중에 존재하는 여러 영양소들(미생물이 발효를 하여 발효액 중으로 배출시킬 수 있는 영양성분들)을 초산발효를 통해 대사산물로 변화한 후, 배지 중으로 배출시켜 제거함으로써 결과적으로 잔존하는 버섯 잔사물에는 미생물이 대사할 수 없는 식이섬유만을 농축시키는 것이다. In general, 'concentration and separation of a specific ingredient' means increasing the content of the ingredient in the base (the final product is obtained when it is obtained in powder form). It also means to concentrate. The present invention relates to a method of concentration and separation by the latter method. That is, the method of concentrating and separating the dietary fiber from the mushroom of the present invention, after changing various nutrients (nutrients that microorganisms can ferment and release into the fermentation broth) into metabolites after fermentation, By discharging it into the medium and removing it, the remaining mushroom residues concentrate only the dietary fiber that microorganisms cannot metabolize.
이하, 본 발명의 과제 해결 수단을 각 단계별로 세분하여 하기에서 더욱 상세히 설명하고자 한다. Hereinafter, the problem solving means of the present invention will be described in more detail below by subdividing each step.
(1) 버섯을 초산발효시키는 단계(a)(1) acetic acid fermentation of mushrooms (a)
본 단계는 준비된 버섯을 초산발효시키는 단계이다. 초산발효는 버섯에 물을 첨가한 후, 초산발효를 수행할 수 있는 미생물을 접종함으로써 수행될 수 있다. 미생물로는 초산발효를 수행할 수 있는 것이라면 어느 것을 사용하여도 무방하며, 아세토박터 아세티(Acetobacter aceti)를 일 예로 사용할 수도 있다. This step is a step of acetic acid fermentation of the prepared mushrooms. Acetic acid fermentation may be carried out by adding water to the mushrooms, and then inoculating microorganisms capable of acetic acid fermentation. As the microorganism, any one that can perform acetic acid fermentation may be used, and acetobacter aceti may be used as an example.
한편, 초산 발효를 위한 배지에는 버섯 외에 바람직하게 당을 비롯한 여러 미생물의 생육을 촉진할 수 있는 성분이나, 초산발효를 촉진할 수 있는 물질을 부수적으로 첨가하는 것도 좋다. 또한, 초산발효를 촉진시키기 위해 통기(aeration) 조건을 도입할 수도 있다. 초산발효는 호기적 조건에서 그렇지 않은 경우에 비하여 촉진되기 때문이다. On the other hand, to the medium for acetic acid fermentation, in addition to the mushroom, it is also preferable to additionally add a component capable of promoting the growth of various microorganisms including sugars, and a substance capable of promoting acetic acid fermentation. In addition, aeration conditions may be introduced to promote acetic acid fermentation. This is because acetic acid fermentation is promoted in aerobic conditions as compared to otherwise.
본 단계에서 사용되는 생버섯은 특정의 것에 국한되는 것은 아니고, 느타리버섯을 포함하여 여러 식용버섯을 사용할 수 있다. The raw mushroom used in this step is not limited to a specific one, and various edible mushrooms, including oyster mushroom, can be used.
본 단계에서의 초산발효는 유가식 발효 및 반복 회분 발효 등의 다양한 발효 방법을 통해서 수행할 수 있으나, 바람직하게는 오염의 방지 및 공정의 단순화 측면에서 회분발효가 좋다. Acetic acid fermentation in this step can be carried out through a variety of fermentation methods, such as fed-batch fermentation and repeated batch fermentation, but preferably ash fermentation in terms of prevention of contamination and simplification of the process.
본 단계에서의 초산발효 시간은 바람직하게 pH가 품질관리 지침에 적합한 pH 3.5에 도달하였을 때까지 수행하는 것이 좋다. 다만, 시간에 대한 경제성을 높이기 위해서 통기를 통해 발효시간을 단축시킬 수도 있다. Acetic acid fermentation time in this step is preferably carried out until the pH has reached pH 3.5 suitable for quality control guidelines. However, the fermentation time may be shortened through aeration to increase the economics of time.
한편, 바람직하게 초산발효는 초기 당 농도 13~28%(w/v)로 20~30℃의 온도에서 15일 이상 수행하는 것이 좋다. 이상의 조건에서 잡균에 의한 오염을 방지할 수 있고, 품질관리 지침에 적합한 제품의 pH인 3.5 이하에 용이하게 도달할 수 있기 때문이다. On the other hand, preferably, acetic acid fermentation is preferably carried out for 15 days or more at a temperature of 20 ~ 30 ℃ at an initial sugar concentration of 13 ~ 28% (w / v). This is because contamination by various bacteria can be prevented under the above conditions, and the pH of the product conforming to the quality control guidelines can be easily reached 3.5 or less.
(2) 발효 후, 발효액을 제거하고 (2) After fermentation, the fermentation broth is removed 잔사를Residue 회수하는 단계(b) Recovering step (b)
본 단계에서는 상기의 초산발효 결과 생성된 발효액을 제거하고 남은 버섯 잔사를 회수한다. 발효가 완료되면 위에 상등액이 뜨는데 이를 제거함으로써 버섯 잔사를 회수할 수 있다. 회수 후, 수용성 분획을 더욱 제거하기 위해 버섯 잔사를 압축하여 발효액을 짜내는 것도 좋다. In this step, the fermentation broth produced as a result of acetic acid fermentation is removed and the remaining mushroom residues are recovered. When the fermentation is complete, a supernatant floats on the top, which can be recovered to remove the mushroom residue. After recovery, the mushroom residue may be compressed to squeeze the fermentation broth to further remove the aqueous fraction.
(3) 회수한 (3) recovered 잔사물을Residue 물로 반복 세척하는 단계(c) Repeated washing with water (c)
본 단계에서는 회수한 잔사물을 물로 반복 세척한다. 초산발효를 거친 버섯 잔사는 강한 산취를 나타내는데, 이는 건조 후에도 제거되기 어려워, 최종 제품의 기호도에 악영향을 미친다. 따라서 건조 전단계에서 이를 제거할 필요가 있는데, 물로 반복 세척하면 산취가 제거된다. 물을 이용한 세척은 바람직하게 버섯 잔사에 그 3배 부피의 물을 첨가하여 1시간 이상 담가 둔 후, 반복 세척하는 방식으로 5회 이상 실시하는 것이 좋다.In this step, the recovered residue is washed repeatedly with water. Acetic acid-fermented mushroom residues exhibit strong acid odor, which is difficult to remove even after drying, adversely affecting the palatability of the final product. Therefore, it is necessary to remove it in the pre-drying step. Repeated washing with water removes acid odor. Washing with water is preferably carried out at least five times by adding a three-fold volume of water to the mushroom residue and soaking it for at least one hour, followed by repeated washing.
(4) 세척한 (4) washed 잔사물을Residue 건조시키는Desiccant 단계(d) Step (d)
본 단계에서는 상기의 물로 세척한 잔사물을 건조시키는 단계이다. 건조는 자연건조, 열풍건조 등의 공지의 다양한 방법을 통해 수행할 수 있으나, 바람직하게 60℃의 열풍건조기를 이용하여 12시간 이상 충분히 건조하여 수분을 제거하는 것이 좋다.In this step, the residue washed with water is dried. Drying may be carried out through various known methods such as natural drying and hot air drying, but preferably, the water is sufficiently dried for at least 12 hours using a hot air dryer at 60 ° C. to remove moisture.
(5) 건조한 (5) dry 잔사물을Residue 분쇄하는 단계(e) Grinding step (e)
본 단계에서는 건조된 버섯의 잔사물을 분쇄하는 단계이다. 분쇄는 공지의 다양한 방법으로 수행할 수 있으나, 바람직하게는 조분쇄를 거친 후, 미세분쇄를 수행하는 2단계 분쇄법을 사용하는 것이 좋다. 건조된 버섯발효 식이섬유 분획은 조직의 결합 강도가 높기 때문에 미세분쇄 전에 분쇄기를 이용하여 조분쇄를 하는 것이 필요하기 때문이다. 조분쇄 후에는 미세분쇄, 일 예로서 싸이클로밀을 이용하여 미세분쇄 작업을 수행하는 것이 바람직하며, 이상의 과정을 통해 입자가 균일한 미세분말을 얻을 수 있다.In this step, the residue of the dried mushroom is pulverized. Grinding may be carried out by a variety of known methods, preferably after coarse grinding, it is preferable to use a two-step grinding method to perform fine grinding. This is because the dried mushroom fermented dietary fiber fraction has a high binding strength, so it is necessary to coarse grind using a grinder before the fine grinding. After the coarse grinding, it is preferable to perform a fine grinding operation using fine grinding, for example, cyclomill, and through the above process, a fine powder with uniform particles can be obtained.
이상 상기에서 살펴본 과제 해결 수단에 의해 본 발명은 고농도로 농축된 식이섬유 분말을 버섯으로부터 분리하여 제공한다. The present invention by the above-described problem solving means provides a high concentration of dietary fiber powder separated from the mushroom.
하기의 실험에 의하면, 생버섯의 건조분말 중에 7.7% 존재하는 식이섬유가 본 발명의 농축 및 분리방법에 의할 경우 최종 회수된 고형분 중 43.1%를 차지하도 록 농축됨이 확인되었다. According to the following experiment, it was confirmed that 7.7% of the dietary fiber in the dry powder of raw mushrooms was concentrated to occupy 43.1% of the final recovered solids by the concentration and separation method of the present invention.
이와 같이 농축된 식이섬유는 난소화성으로 인해 다이어트 식품 산업에 적극 활용될 수 있다.The concentrated dietary fiber can be actively used in the diet food industry due to the indigestion.
