Description
본 발명은 감귤, 사과, 오렌지, 레몬 등의 껍질에 존재하는 펙틴을 산으로 처리하여 펙틴을 제조하는 방법에 관한 것이다. 펙틴은 주로 감귤류나 사과, 오렌지, 레몬 등의 껍질에서 추출되는 다당류로서 중금속(납, 수은, 카드뮴, 몰리브덴, 망간 등)과 방사선 금속의 양이온(코발트, 스트론튬, 세슘) 독성예방치료, 콜레스테롤 저하 및 당뇨병, 장질환, 간장질환, 비만 등에 매우 효과적인 물질이다.The present invention relates to a method for preparing pectin by treating pectin present in peels of citrus fruits, apples, oranges, lemons and the like with an acid. Pectin is a polysaccharide mainly extracted from citrus fruits, apples, oranges, lemons, etc. It is very effective for diabetes, bowel disease, liver disease, obesity, etc.
현 시장은 펙틴을 주로 유럽에서 전통적인 방법으로 생산하여 공급하고 있으며, 전통적인 방법은 추출 시에 염산을 사용하므로 가역 반응으로 인하여 추출 시간이 12∼24시간이나 소요되고 다량의 염산을 필요로 한다.The current market produces and supplies pectin mainly in the traditional method in Europe. Since the conventional method uses hydrochloric acid for extraction, it takes 12 to 24 hours of extraction time due to the reversible reaction and requires a large amount of hydrochloric acid.
따라서 많은 양의 폐수와 폐기물이 발생한다. 또한 분리 및 농축이 filter press나 고온저압농축 설비를 사용하고 있어 에너지 소비가 많은 반면 순도는 떨어지는 단점을 가지고 있다.Therefore, a large amount of waste water and waste are generated. In addition, the separation and concentration uses a filter press or a high temperature low pressure concentration facility, which consumes a lot of energy but has a disadvantage in that purity is low.
본 발명은 감귤, 사과, 오렌지, 레몬 등의 껍질에 존재하는 펙틴을 산으로 처리하여 펙틴을 짧은 시간에 저비용, 고순도로 제조하는 방법을 제공하는 것이다.The present invention is to provide a method for producing pectin in low cost and high purity in a short time by treating the pectin present in the peel of citrus fruits, apples, oranges, lemons and the like with an acid.
일반적으로 펙틴은 매우 수화되기 쉬우며 흡습성이 강하고 물에는 친수성 교질 용액을 형성하여 외관상 점도는 매우 높다. 추출 공정 중에도 높은 점도로 인하여 분리, 농축에 문제가 발생될 수 있어 항상 60∼80℃를 유지하며 추출을 해야 한다. 이러한 펙틴을 추출하는 데에는 일반적으로 산 처리에 의한 추출, 효소 처리에 의한 추출이 있으며 처리하는 산의 종류에 따라 수율 및 시간이 크게 차이가 있다.In general, pectin is very hydrated, hygroscopic, and forms a hydrophilic colloidal solution in water, which has a very high apparent viscosity. Even during the extraction process, problems may occur in separation and concentration due to the high viscosity, so the extraction should be maintained at 60 to 80 ° C. Extracting such pectin generally includes extraction by acid treatment and extraction by enzyme treatment, and yield and time vary greatly according to the type of acid to be treated.
또한, 펙틴의 기능성과 밀접한 관계가 있는 메틸에스테르기는 알칼리에 의해 쉽게 가수분해되어 그 정도에 따라 다양한 기능을 갖게 된다.In addition, the methyl ester group, which is closely related to the functionality of pectin, is easily hydrolyzed by alkali and has various functions depending on the extent thereof.
본 발명은 염산 이외에 식용 인산을 사용함으로서 추출 시간을 1시간으로 줄일 수 있었고, 그 결과 산 사용량도 매우 줄일 수 있었다. 또한 데칸터(decanter)와 같은 분리기나 멤브레인 여과기(membrane filtration) 등 새로운 설비를 적절히 선택하여 사용함으로써 공정 단순화 및 에너지 절감을 하는 반면 순도가 높은 펙틴을 얻을 수 있었다.The present invention was able to reduce the extraction time to 1 hour by using edible phosphoric acid in addition to hydrochloric acid, and as a result it was also possible to reduce the amount of acid used. In addition, the use of new equipment, such as separators such as decanters or membrane filtration, can be used to obtain high-purity pectin while simplifying the process and saving energy.
본 발명에서는 펙틴 추출과 기능성 부여를 분리하여 추출공정과 정제공정으로 나누었다.In the present invention, pectin extraction and functional impartment were separated and divided into extraction process and purification process.
[제 1공정][Step 1]
세 척wash
감귤, 사과, 오렌지, 레몬 등의 껍질을 건조하여 가로 4mm, 세로 2∼40mm 입자크기의 원료를 온수와 10% 염산(1L/10kg원료 비율)을 받아둔 추출기에 투입한다. 염산을 사용하는 것은 이어지는 추출 과정에서 펙틴을 빨리 그리고 쉽게 추출하기 위한 상황을 만들어 주기 위함이다. 이때, 온수의 온도는 40∼60℃정도를 유지한다. 40분 정도의 순환을 통하여 껍질의 이물질 등을 세척한다. 다시 온수를 투입하여 세척을 마무리한다.Dry the peels of citrus fruits, apples, oranges, lemons, etc., and feed the raw material with a grain size of 4 mm and 2 to 40 mm in a hot water and 10% hydrochloric acid (1L / 10kg raw material ratio). The use of hydrochloric acid is intended to create a situation for the rapid and easy extraction of pectin in the subsequent extraction process. At this time, the temperature of the hot water is maintained at about 40 ~ 60 ℃. After 40 minutes, clean the foreign substances on the shell. Add warm water again to complete the wash.
추 출extraction
추출기에 다시 90∼95℃의 고온 열수를 투입하고 10% 염산(2.5L/10kg)과 85% 인산을 150∼200g/10kg원료의 비율로 투입하여 약 30분 정도 교반하면서 추출한다. 열수와 혼합하는 이유는, 건조된 상태인 감귤 등의 껍질을 불려서 가수분해를 용이하게 함과 동시에 가수분해를 위한 수분을 제공함에 있다. 추출 후에 분리기를 사용하여 원료와 액을 분리하다. 분리기로는 수평형인 데칸터 및 수직형 원심분리기가 가능하며 특히, 4500rpm의 데칸터를 사용하는 것이 바람직하다. 상온에서 펙틴은 겔 형성 능력이 매우 좋아 점도가 매우 높으므로 80℃이상의 고온에서 작업하여야 한다.Into the extractor, hot hot water at 90-95 ° C is added again, and 10% hydrochloric acid (2.5L / 10kg) and 85% phosphoric acid are added at a rate of 150-200g / 10kg raw material and extracted with stirring for about 30 minutes. The reason for mixing with hot water is to dry the peel of citrus and the like in a dried state to facilitate hydrolysis and to provide water for hydrolysis. After the extraction, the raw material and the liquid are separated using a separator. The separator can be a horizontal decanter and a vertical centrifuge, and it is particularly preferable to use a decanter of 4500 rpm. At room temperature, pectin has good gel formation ability and high viscosity. Therefore, pectin should be operated at high temperature of over 80 ℃.
농축 및 건조Concentrated and dried
멤브레인 여과기를 사용하여 농축을 실시한다. 바람직하기로는 0.01∼0.5 미크론(micron)의 멤브레인 여과기를 사용하여 농축을 실시한다. 가장 바람직하기로는 0.14∼0.2 미크론의 멤브레인 여과기를 사용하여 농축을 실시하는 것이다. 농축은 상기 추출물 총량 중 고형분이 10∼20%가 되도록 실시한다. 1차 농축 후에도 순도가 높아지지 않을 경우 물을 보충하여 2, 3차 농축을 실시하여 순도를 높여야 한다. 농축액을 분무 건조를 통하여 건조하여 분말 펙틴을 얻는다.The concentration is carried out using a membrane filter. Preferably, concentration is carried out using a membrane filter of 0.01 to 0.5 microns. Most preferably, the concentration is performed using a membrane filter of 0.14-0.2 micron. Concentration is carried out so that the solid content of the total amount of the extract is 10 to 20%. If the purity does not increase even after the first concentration, the water should be supplemented with 2nd and 3rd concentrations to increase the purity. The concentrate is dried via spray drying to obtain a powder pectin.
[제 2공정][Step 2]
정 제refine
펙틴의 유기산기가 메틸에스테르화된 정도를 나타내는 Degree of Esterification(DE)값을 조정하여 저메톡실 펙틴을 얻기 위하여 알칼리 처리를 하고(M.Corrediget al., 2000 IFT Annual Meeting), 이를 중화한 후 알콜로 순도를 높이는 공정이다. 먼저 반응 용기에 건조된 펙틴을 약 5kg정도 투입한 후에 65% 알콜을 20∼30kg 투입한 후에 45% NaOH를 500∼1,000g투입하여 반응시킨다. 이를 여지를 사용하여 분리한다. 그 후에 다시 반응 용기에 투입한 후 65% 알콜과 35% 염산을 투입하되, 염산은 처음 500g부터 시작하여 리트머스 용지로 pH가 7이 되는 양인 1800g을 투입하여 Na+나 Cl-을 침전시켜 분리한다. 원하는 순도에 도달할 때까지 65% 알콜로 불순물을 침전시킨다. 상기 침전 과정이 완료된 후에 95% 무수 알콜을 사용하여 수분을 분리한 후에 스크류 건조기(screw dryer)를 통하여 건조시킨다.Adjust the Degree of Esterification (DE) value, which indicates the degree of methyl esterification of the organic acid group of pectin, to alkali treatment to obtain low methoxyl pectin (M. Corredig et al ., 2000 IFT Annual Meeting) To increase the purity. First, about 5 kg of dried pectin is added to the reaction vessel, and 20-30 kg of 65% alcohol is added, followed by 500-1,000 g of 45% NaOH. Use this to separate them. After that, 65% alcohol and 35% hydrochloric acid are added again, and hydrochloric acid starts from the first 500 g, and 1800 g of pH 7 is added to litmus paper to precipitate Na + or Cl - to separate. . The impurities are precipitated with 65% alcohol until the desired purity is reached. After the precipitation process is completed, the water is separated using 95% anhydrous alcohol, and then dried through a screw dryer.

Concentration was performed through a 0.2 micron membrane filter. The temperature of the concentrator was 80 ℃ and after the first concentration, 300L of hot water was added to perform the second and third concentration. After concentration, the mixture was dried through a spray dryer using air at 180 ° C. The purity of the dried pectin was 90% and the DE value was 60 without adjustment during the extraction process.
건조된 분말 펙틴 5kg을 정제 용기에 넣고 65% 알콜 30kg과 45% NaOH 650g을 투입하여 5분 교반한 후 여지를 사용하여 분리하였다(정제1). 펙틴을 다시 정제 용기에 넣고 65%알콜 30kg과 35%염산 1,800g을 투입하여 다시 5분 교반한 후 분리하였다(정제2). 정제 1과 2를 2차례 더 반복하였다. 95% 무수 알콜 6kg을 사용하여 수분을 제거시키고 분리한 후 건조하였다. 정제된 펙틴은 DE값이 35이었고 순도는 95%이었다(종래 기술에 따를 경우의 펙틴의 순도는 75%임).5 kg of dried powder pectin was placed in a purification vessel, and 30 kg of 65% alcohol and 650 g of 45% NaOH were added thereto, stirred for 5 minutes, and separated using a filter paper (Table 1). The pectin was put back into the refining container, and 30 kg of 65% alcohol and 1,800 g of 35% hydrochloric acid were added thereto, followed by stirring for 5 minutes and separated (purification 2). Tablets 1 and 2 were repeated two more times. Water was removed using 6 kg of 95% anhydrous alcohol, separated and dried. Purified pectin had a DE value of 35 and a purity of 95% (pectin purity of 75% according to conventional techniques).
본 발명을 통해 종래 폐기 처리되고 있던 감귤, 사과, 오렌지 등의 껍질에서 펙틴을 추출할 수 있으므로 연 600t 규모의 펙틴 수입 대체 효과를 기대할 수 있으며 중금속, 방사성 금속의 양이온 독성 예방치료, 장질환, 간장질환 등의 예방치료물질인 펙틴을 다량 생산할 수 있다.Pectin can be extracted from peels of tangerines, apples, oranges, and the like, which have been conventionally disposed of through the present invention, and thus, the effect of importing pectin of 600 tons per year can be expected, and cationic toxicity prevention treatment of heavy metals and radioactive metals, intestinal diseases, and soy It can produce a large amount of pectin, a prophylactic agent for diseases and the like.
또한, 본 발명은 기존의 유럽방식이 다량의 염산은 투입하여 많은 폐수와 폐기물을 발생시키고 분리 및 농축과정에서 많은 설비와 에너지를 사용하여 생산되는 고비용 저효율의 공정의 한계성에서 벗어나 인산, decanter 등의 분리기, membrane 여과기 사용과 같은 신기술을 도입하여 고효율 저비용의 환경 친화적인 펙틴 추출 방법을 제공하는 것이다.In addition, the present invention generates a large amount of hydrochloric acid by inputting a large amount of hydrochloric acid in the existing European method, and is free from the limitations of the high-cost and low-efficiency process produced by using a lot of equipment and energy in the separation and concentration process, such as phosphoric acid and decanter. The introduction of new technologies, such as the use of separators and membrane filters, provides a highly efficient, low cost, environmentally friendly pectin extraction method.
