Description
본 발명은 녹차두부에 관한 것으로서, 보다 상세하게는 두부에 녹차의 유효성분이 함유되도록 함으로서 건강식으로 유용하게 취식할 수 있을 뿐만 아니라 제조된 두부의 신선도가 장시간 유지되며, 선명한 녹색의 색상을 유지할 수 있어 상품성이 우수한 녹차분을 이용한 녹차두부의 제조방법 및 그 방법에 의하여 제조된 녹차두부에 관한 것이다.The present invention relates to green tea tofu, and more specifically, by containing the active ingredient of green tea tofu can be usefully eaten as a healthy food, the freshness of the prepared tofu is maintained for a long time, can maintain a vivid green color It relates to a method for producing green tea tofu using green tea powder having excellent marketability and green tea tofu prepared by the method.
종래로 부터 두부는 콩을 가공하여 제조되는 식품의 하나로서, 단백질을 포함하여 각종 영양소가 다량 포함되어 있어, 다양한 요리과정을 통해 우리의 식단에 자주 오르고 있다.Conventionally, tofu is one of the foods produced by processing soybeans, and contains a large amount of various nutrients, including protein, and is often on our diet through various cooking processes.
상기 두부는 일반적으로 콩을 세척하고 24시간 동안 물에 침지시켜 불린 다음, 불려진 콩에 2배 분량의 물을 투입하여 분쇄하고, 상기 분쇄물을 100℃의 온도에서 30∼40분 정도 가열하여 가공물을 형성하고, 상기 가공물을 체로 여과하여 두유액과 비지로 분리하고, 상기 분리된 두유액을 80∼90℃의 온도로 가열하고 두유액의 0.01중량%의 응고제를 첨가하여 응고시키고, 이를 틀에 넣고 압축하여 탈수하고 성형함으로서 제조된다.The tofu is generally soaked and soaked in water for 24 hours, soaked, and then crushed by adding twice the amount of water to the soaked soybeans, and heating the ground product at a temperature of 100 ° C. for about 30 to 40 minutes. The resulting product was filtered through a sieve, separated into soymilk and sewage, and the separated soymilk was heated to a temperature of 80-90 ° C. and coagulated by adding 0.01% by weight of a coagulant in the soymilk. Prepared by compression, dehydration and molding.
이때, 상기 두부의 제조공정에서 응고제를 첨가하여 성형하는 과정에 따라서 일반두부와 연두부, 순두부 등으로 분류된다. 즉, 응고제의 첨가량이나 성형방법의 차이에 따라 순두부, 연두부 및 일반두부로 분류되게 된다. 이러한 두부 제품은 지금까지 콩 자체만을 이용하여 제조되었으나, 경제성장과 더불어 국민생활의 고급화, 건강지향화, 간편화 경향으로 기능성이 가해지는 방향으로 발전되고 있다.At this time, according to the process of forming by adding a coagulant in the manufacturing process of the tofu is classified into general tofu, soft tofu, soft tofu and the like. That is, according to the difference in the amount of coagulant added or the molding method, it is classified into soft tofu, soft tofu and normal tofu. These tofu products have been manufactured using soybeans only until now, but are being developed in the direction of increasing functionality along with economic growth and the enhancement of national life, health orientation, and simplicity.
상기 기능성 두부의 일환으로 국내 공개특허공보 제2001-85119호의 '두부 제조방법'에서는 녹차분말을 물에 투입하여 희석액을 만들고, 상기 희석액에 두부콩을 침지시켜 발아시킨 다음 이를 이용하여 두부를 제조함으로서 녹차분의 유효성분이 포함되도록 하여 건강식으로 유용하게 취식할 수 있을 뿐만 아니라 신선도의 유지기간을 증가시킨 두부의 제조방법에 관한 기술을 개시하고 있다.As a part of the functional tofu in the 'Tofu manufacturing method' of Korean Patent Laid-Open Publication No. 2001-85119, green tea powder is added to water to make a diluting solution, soaking the tofu soybeans in the diluting solution, and then preparing tofu using the same. The present invention relates to a method for preparing tofu, which includes an active ingredient of green tea powder, which can be usefully eaten as a health food, as well as increasing the maintenance period of freshness.
그러나 상기와 같이 녹차분말을 포함하는 희석액에 두부콩을 침지시켜 발아시킨 다음 이를 이용하여 두부를 제조하는 경우 발아된 콩에 녹차분말의 유효성분이 함유될 수 있으나 그 효과가 미미하고, 또한 제조된 두부에서 특유의 비릿한 맛이 나는 단점이 있다.However, when the tofu bean is immersed in a dilution solution containing the green tea powder as described above, and then tofu is made using the same, the effective ingredient of the green tea powder may be contained in the germinated bean, but the effect is insignificant, and the prepared tofu Disadvantages of the distinctive taste of the crisp.
이러한 문제점으로 인하여 불려진 콩에 물을 투입하여 분쇄하는 과정에서 녹차분을 투입하여 함께 분쇄함으로서 녹차의 유효성분이 다량 함유되도록 하여 건강식으로 유용하게 취식할 수 있을 뿐만 아니라, 녹차의 유효성분에 의한 두부 특유의 비릿한 맛을 없애 두부의 맛을 향상시킨 두부의 제조방법이 공지되어 있다.Due to these problems, by adding water to the soybeans called crushed green tea powder, the green tea powder is pulverized together so that the active ingredient of green tea can contain a large amount of green tea. It is known to manufacture tofu that improves the taste of tofu by eliminating the uneven taste of tofu.
그러나 상기와 같이 콩을 분쇄하는 과정에서 녹차분을 투입하여 제조된 두부의 경우 녹차분의 색상에 의해 녹색을 띠게 되나, 색상이 연한 녹색을 띠거나 갈색 또는 노란색으로 쉽게 변색되어 제품의 질이 저하되는 단점이 있다.However, in the case of tofu prepared by adding green tea powder in the process of grinding beans as described above, the color becomes green by the color of green tea powder, but the color is light green or is easily changed to brown or yellow, thereby degrading product quality. There is a disadvantage.
이에 본 발명은 두부에 녹차의 유효성분이 함유되도록 함으로서 건강식으로 유용하게 취식할 수 있을 뿐만 아니라 제조된 두부의 신선도가 장시간 유지되며, 선명한 녹색의 색상을 유지할 수 있어 두부의 질을 높일 수 있도록 한 녹차분을 이용한 녹차두부의 제조방법 및 그 방법에 의하여 제조된 녹차두부를 제공하는데 그 목적이 있다.Therefore, the present invention not only can be usefully eaten as a health food by containing the active ingredient of green tea in the tofu, but also maintains the freshness of the prepared tofu for a long time, and can maintain the vivid green color to improve the quality of tofu It is an object of the present invention to provide green tea tofu using powder and green tea tofu prepared by the method.
상기한 목적을 달성하기 위하여 본 발명은The present invention to achieve the above object
물에 침지시켜 불린 콩에 2배의 물을 투입하여 분쇄하고, 상기 분쇄물을 100℃에서 30∼40분 정도 가열하여 가공물을 형성하고, 상기 가공물을 체로 여과하여 두유액과 비지로 분리하고, 상기 분리한 두유액에 대하여 녹차분을 투입하여 24시간 숙성시킨 후 체로 여과하여 고형분을 제거하고, 이를 80∼90℃로 가열한 후 두유액의 0.01중량%의 응고제를 첨가하여 응고시킨 다음 틀에 넣고 압축하여 탈수하고 성형하는 두부의 제조방법에 있어서,2 times of water was added to the soybeans soaked in water and pulverized. The pulverized product was heated at 100 ° C. for about 30 to 40 minutes to form a processed product. Green tea powder was added to the separated soymilk solution and aged for 24 hours, followed by filtration through a sieve to remove solids, which was then heated to 80-90 ° C and coagulated by adding 0.01% by weight of a coagulant in the soymilk solution. In the manufacturing method of tofu which is inserted, compressed, dehydrated and molded,
두유액에 녹차분을 첨가하여 숙성하는 과정에서 두유액 100중량부에 대하여 녹차분 5 내지 20중량부와 함께 식물성유 2 내지 14중량부를 투입하여 숙성시키는 것을 특징으로 하는 녹차분을 이용한 녹차두부의 제조방법을 제공한다.Green tea tofu with green tea powder, characterized in that by adding green tea powder to soy milk solution, aged 2-14 parts by weight of vegetable oil with 5-20 parts by weight of green tea powder with respect to 100 parts by weight of soy milk solution. It provides a manufacturing method.
이하 본 발명을 보다 상세하게 설명하기로 한다.Hereinafter, the present invention will be described in more detail.
본 발명에서는 녹차두부를 제조하기 위하여 먼저 공지의 방법으로 콩을 물에 침지시켜 불린 다음, 상기 불린콩에 약 2배의 물을 투입하여 분쇄하고, 상기 분쇄물을 100℃에서 30∼40분 정도 가열하여 가공물을 형성하게 된다.In the present invention, in order to prepare green tea tofu, soybeans are first immersed in water by a known method, and then pulverized by adding about twice as much water to the soaked soybeans. It is heated to form a workpiece.
이와 같이 형성한 가공물을 체로 여과하여 두유액과 비지로 분리하게 된다. 이때, 통상의 두부 제조방법에 따르면, 상기 분리된 두유액을 가열한 후 응고제를 투입하여 응고시키게 된다. 그러나 본 발명에서는 상기 분리된 두유액에 녹차분과 식물성유를 투입하여 숙성시킨 다음 이를 체로 재여과하여 두유액과 고형분으로 분리하여 고형분을 제거한 다음, 분리된 두유액을 가열한 후 응고제를 투입하여 응고시키게 된다.The workpiece thus formed is filtered through a sieve and separated into soymilk and sebum. At this time, according to the conventional tofu production method, the separated soymilk is heated and then coagulated by adding a coagulant. However, in the present invention, green tea powder and vegetable oil are added to the separated soymilk solution and matured, followed by re-filtration through a sieve to separate the soymilk and solids to remove solids, followed by heating the separated soymilk solution, and then adding a coagulant. Let's go.
상기에서 녹차분은 녹차의 유효성분이 두부에 포함될 수 있도록 함과 동시에 녹차에 함유된 성분으로 인하여 두부 특유의 비릿한 맛을 제거하며, 제조된 두부의 녹색이 선명하게 나타날 수 있도록 하기 위해 첨가하게 된다.The green tea powder is added to enable the active ingredient of green tea to be included in the tofu and at the same time remove the vivid taste peculiar to the tofu due to the ingredients contained in the green tea, and to make the green color of the prepared tofu appear clearly.
특히, 녹차의 주성분인 폴리페놀은 여러 종류의 물질과 쉽게 결합하여 인체내의 중금속제거, 항산화작용, 발암성분의 무력화, 해독 작용이 우수하며 각종 아미노산, 비타민C, 토코페롤, 카로틴, 칼륨, 인이 풍부하며 사포닌 성분이 포함되어 거담, 소염, 항균작용이 탁월할 뿐만 아니라 플라보노이드의 향기와 사포닌의 쌉쌀한 맛은 콩 특유의 비릿한 맛을 제거하여 두부의 맛을 향상시키게 된다.In particular, polyphenol, the main component of green tea, is easily combined with various kinds of substances to remove heavy metals in the human body, antioxidant activity, neutralization of carcinogenic components and detoxification, and is rich in various amino acids, vitamin C, tocopherol, carotene, potassium, phosphorus In addition, the saponin ingredient is not only excellent in expectoration, anti-inflammatory and antibacterial effects, but also the flavor of flavonoids and the bitter taste of saponins improve the taste of tofu by eliminating the vivid taste of soybean.
이때, 녹차분의 첨가량이 두유액 100중량부에 대하여 5중량부 미만으로 첨가될 경우 두부 특유의 비릿한 맛이 제거되지 못하며 두부의 색상 또한 선명하지 못하여 두부의 질이 저하되는 단점이 있으며, 녹차분의 첨가량이 두유액 100중량부에 대하여 20중량부를 초과할 경우 녹차 특유의 쌉쌀한 맛이 강하게 나고 두부의 맛이 감소되는 단점이 있다. 따라서 녹차분의 첨가량은 두유액 100중량부에 대하여 5 내지 20중량부 첨가하는 것이 바람직하다.At this time, if the addition amount of green tea powder is less than 5 parts by weight based on 100 parts by weight of soy milk liquid, the peculiar taste of the tofu cannot be removed and the color of the tofu is not clear and the quality of the tofu is deteriorated. When the amount of added exceeds 20 parts by weight with respect to 100 parts by weight of soy milk has a disadvantage that the strong taste peculiar to green tea is strong and the taste of tofu is reduced. Therefore, the addition amount of the green tea powder is preferably added 5 to 20 parts by weight based on 100 parts by weight of soymilk.
또한, 본 발명에서는 녹차분과 함께 식물성유를 투입하게 되는데, 식물성유는 제조된 두부의 비릿한 맛을 없애고 고소한 맛을 유도하며, 녹차두부의 색상이 변색되는 것을 방지함과 동시에 신선도가 장시간 유지될 수 있도록 하기 위하여 첨가된다.In addition, in the present invention, the vegetable oil is added together with the green tea powder, which removes the vivid taste of the prepared tofu and induces a savory taste, while preventing the discoloration of the green tea tofu and maintaining freshness for a long time. To be added.
특히, 식물성유 중에서도 콩기름을 사용하는 것이 바람직하다. 상기 콩기름에는 항산화 기능을 갖는 토코페롤이 다량 함유되어 있어 제조된 녹차두부의 색상이 변색되는 것을 효과적으로 억제할 수 있을 뿐만 아니라 신선도가 장시간 유지될 수 있도록 도와준다.In particular, it is preferable to use soybean oil among vegetable oils. The soybean oil contains a large amount of tocopherol having an antioxidant function, which can effectively suppress the discoloration of the produced green tea tofu and help to maintain the freshness for a long time.
이때, 식물성유의 첨가량이 2중량부 미만으로 첨가될 경우 두부 특유의 비릿한 맛이 제거되지 못하며, 두부의 색상이 변질되고, 장시간 보관시 신선도가 떨어져 제품의 질이 저하되는 단점이 있으며, 식물성유의 첨가량이 14중량부를 초과할 경우 식물성유의 과다로 식물성유 특유의 냄새가 강하게 남으로 제품의 질이 저하되는 단점이 있다. 따라서 식물성유의 첨가량은 2 내지 14중량부 첨가하는 것이 바람직하다.At this time, when the amount of vegetable oil added is less than 2 parts by weight, the vivid taste of tofu cannot be removed, the color of the tofu is deteriorated, and the quality of the product is lowered when stored for a long time. If the amount exceeds 14 parts by weight, there is a disadvantage in that the quality of the product is lowered due to the strong smell of vegetable oil due to the excessive amount of vegetable oil. Therefore, it is preferable to add 2-14 weight part of vegetable oil addition amounts.
상기한 범위내에서 두유에 녹차분과 식물성유를 투입하고, 이를 24시간 숙성시키게 되면, 녹차분에 함유되어 있는 유효성분이 용출되어 두유에 포함되게 되며, 두유의 색상은 녹색을 나타내게 된다. 이때, 숙성은 20∼30℃에서 실시하는 것이 녹차의 유효성분 용출을 고려하여 바람직하다.When the green tea powder and vegetable oil are added to the soy milk within the above-described range, and aged for 24 hours, the active ingredient contained in the green tea powder is eluted and included in the soy milk, and the color of the soy milk is green. At this time, aging is preferably performed at 20 to 30 ° C in consideration of dissolution of the active ingredient of green tea.
숙성이 완료되면 이를 체로 재여과하여 고형분을 제거하고, 여과된 두유액을 이용하여 공지된 방법에 따라 이를 80∼90℃로 가열한 후 두유액의 0.01중량%의 응고제를 첨가하여 응고시킨 다음, 이를 틀에 넣고 압축하여 탈수하고 성형하게 되면 본 발명에 따른 녹차두부를 제조할 수 있게 된다.After aging is completed, the resultant is filtered again through a sieve to remove solids, and after heating to 80-90 ° C. according to a known method using a filtered soymilk solution, it is solidified by adding 0.01% by weight of a coagulant in the soymilk solution. When it is put into a mold and dehydrated and molded, it is possible to manufacture green tea tofu according to the present invention.
이때, 상기에서 본 발명은 일반적인 두부제조방법을 예를 들어 설명하였으나, 상기 두부의 제조과정에서 응고제의 첨가량을 조절하거나 성형과정을 통상의 방법으로 적절히 제어하게 되면 연두부나 순두부 등 다양한 종류의 녹차두부의 제조가 가능하게 된다.At this time, the present invention has been described a general manufacturing method of tofu, for example, if the amount of coagulant is adjusted in the manufacturing process of the tofu or if the molding process is properly controlled by a conventional method, various types of green tea tofu, such as soft tofu and soft tofu Can be manufactured.
상기와 같은 과정을 거쳐 제조된 본 발명의 녹차두부는 녹차의 유효성분을 다량 함유하고 있어 건강식으로 유용하게 취식할 수 있을 뿐만 아니라, 두부의 비릿한 맛이 제거되고 고소한 맛이 나며, 특히 선명한 녹색의 색상을 나타내므로 상품성이 매우 우수하다는 이점이 있다.The green tea tofu of the present invention prepared through the process as described above contains a large amount of active ingredients of green tea, which can be usefully eaten as a health food, and also removes the vivid taste of tofu and tastes savory. Since the color is represented, the merchandise is very excellent.
