In addition, it is known to shorten the passage time of the ingested high-fat food in the digestive tract, and to lower the body's absorption of fat by lowering bile acid adsorption and dissolution of cholesterol and triglyceride digestion.

식이섬유 중에서도 난소화성 말토덱스트린은 수용성 식이섬유로 다른 식이섬유에 비하여 혈당억제 작용 및 혈중 중성지질과 콜레스테롤치 저하 효과가 크고, 무엇보다도 냄새 및 점도 측면에서 제형화가 용이하며 산, 열에 대해 안정성이 큰 장점이 있다(우동호 외, 한국영양학회지 31(6): 981-990, 1998).Among the dietary fiber, indigestible maltodextrin is a water-soluble dietary fiber, which is more effective in inhibiting blood glucose, lowering blood triglycerides and cholesterol level than other dietary fibers, and is more easily formulated in terms of smell and viscosity, and more stable in acid and heat. It has advantages (Udong et al., Korean Journal of Nutrition, 31 (6): 981-990, 1998).

이와 같은 장점으로 말미암아 난소화성 말토덱스트린을 제조하고자 하는 다양한 기술들이 많이 개발되어 있는데, 기본적으로는 아밀로수크라아제(EC 2.4.1.4)를 α-1,4 결합을 가지는 수용체 및 자당을 함유한 기질에 첨가하여 반응을 유도하는 방법이 있다. Due to these advantages, various techniques for preparing an indigestible maltodextrin have been developed. Basically, amylosucrase (EC 2.4.1.4) contains a receptor containing α-1,4 and sucrose. There is a method of inducing a reaction by adding to a substrate.

또한, 아밀로수크라아제 외에 글리코겐 가지화 효소(EC 2.4.1.18)를 더불어 사용함으로써 난소화성 말토덱스트린을 제조하는 방법도 알려져 있다(미국특허공개공보 US 2004/0110254 A1, 공개일자 2004. 6. 10).In addition, a method of preparing an indigestible maltodextrin by using a glycogen branching enzyme (EC 2.4.1.18) in addition to amylosucrase is also known (US Patent Publication No. US 2004/0110254 A1, published 2004. 6. 10).

그런데, 상기의 미국공개공보에는 공정상 난소화성 말토덱스트린의 생산 수율을 높일 수 있는 추가적 방법의 개발에 대해서는 특별히 개시된 바가 없다. However, the above-mentioned U.S. publication does not specifically disclose the development of an additional method for increasing the production yield of indigestible maltodextrin in the process.

이에 본 발명은 아밀로수크라아제와 글리코겐 가지화 효소(EC 2.4.1.18)를 사용하여 난소화성 말토덱스트린을 제조하는 방법에 있어서, 난소화성 말토덱스트린의 생산 수율을 높일 수 있는 새로운 방법을 개발하여 제공하는데 그 목적이 있다. Accordingly, the present invention, in the method for producing an indigestible maltodextrin using amylosucrase and glycogen branching enzyme (EC 2.4.1.18), by developing a new method to increase the yield of indigestible maltodextrin The purpose is to provide.

상기 목적을 달성하기 위하여, 본 발명은 자당을 함유한 기질에 아밀로수크라아제(EC 2.4.1.4) 를 첨가하여 반응시키는 단계; 및, 상기 아밀로수크라아제(EC 2.4.1.4) 첨가 반응이 3~12시간 진행된 후, 글리코겐 가지화 효소(EC 2.4.1.18)를 순차적으로 상기 기질에 첨가하여 반응시키는 단계; 를 포함하는 것을 특징으로 하는 난소화성 말토덱스트린의 제조방법을 제공한다. In order to achieve the above object, the present invention comprises the steps of reacting by adding amylosucrase (EC 2.4.1.4) to a substrate containing sucrose; And, after the addition reaction of the amylosucrase (EC 2.4.1.4) for 3 to 12 hours, the step of sequentially adding glycogen branching enzyme (EC 2.4.1.18) to the substrate to react; It provides a method for producing an indigestible maltodextrin comprising a.

이하, 본 발명의 과제 해결 수단에 대해 상세히 설명하고자 한다.Hereinafter, the problem solving means of the present invention will be described in detail.

본 발명은 식후 혈당의 급격한 상승을 억제하는 작용이나 장기 섭취에 의한 혈중 중성 지방이나 콜레스테롤 저하 작용 등을 보여 기능성 식품의 소재로서 널리 이용되고 있는 난소화성 말토덱스트린의 생산 수율을 증대시키기 위한 방법으로, 아밀로수크라아제 및 글리코겐 가지화 효소를 이용하는 효소적 처리방법이다. The present invention is a method for increasing the production yield of indigestible maltodextrin widely used as a material for functional foods by suppressing the rapid rise of blood sugar after meals or by lowering blood triglycerides and cholesterol by long-term intake, It is an enzymatic method using amylosucrase and glycogen branching enzyme.

본 발명의 방법에 의해 생산된 난소화성 말토덱스트린은 RS3 형태이기 때문 에 이용하기 가장 유리한 형태이며, 생촉매로부터 생산되기 때문에 식품의 안전성이 높다.The indigestible maltodextrin produced by the method of the present invention is the most advantageous form to use because it is in the form of RS3, and food safety is high because it is produced from a biocatalyst.

한편, 본 발명에서 사용되는 아밀로수크라아제(Amylosucrase, EC 2.4.1.4, 이하 'AS'로도 칭함)는 자당을 기질로 하여 자당을 포도당과 과당으로 가수분해 한 다음, 다른 알파 1,4 결합을 가지고 있는 수용체 물질에 포도당을 전이시켜주는 효소로써 불용성 또는 수용성 다당체를 생산한다.On the other hand, amylosucrase (Amylosucrase, EC 2.4.1.4, hereinafter referred to as 'AS') used in the present invention hydrolyzes sucrose into glucose and fructose using sucrose as a substrate, and then binds another alpha 1,4. It is an enzyme that transfers glucose to a receptor substance that contains insoluble or soluble polysaccharides.

글리코겐 가지화 효소(Glycogen branching enzyme, EC 2.4.1.18, 이하 'GBE'로도 칭함)은 알파 1,4 결합을 가지는 직쇄형의 글루칸을 가수분해하여 수용체 물질에 알파 1,6 결합으로 전이시켜주는 효소이다. Glycogen branching enzyme (EC 2.4.1.18, hereinafter referred to as GBE) is an enzyme that hydrolyzes linear glucans that have alpha 1,4 bonds and transfers them to alpha 1,6 bonds to receptors. to be.

본 발명의 이상의 특징이 있는 아밀로수크라아제와 글리코겐 가지화 효소(EC 2.4.1.18)를 사용하여 난소화성 말토덱스트린을 제조하는 방법에 있어서, 난소화성 말토덱스트린의 생산 수율을 높일 수 있는 새로운 방법을 개발하여 제공하는데, 그 방법은 자당을 함유한 기질에 아밀로수크라아제(EC 2.4.1.4)를 첨가하여 반응시키는 단계; 및, 상기 아밀로수크라아제(EC 2.4.1.4) 첨가 반응이 3~12시간 진행된 후, 글리코겐 가지화 효소(EC 2.4.1.18)를 순차적으로 상기 기질에 첨가하여 반응시키는 단계로 구성된다. In the method for producing an indigestible maltodextrin by using amylosucrase and glycogen branching enzyme (EC 2.4.1.18) having the above characteristics of the present invention, a novel method for increasing the yield of indigestible maltodextrin The present invention provides and develops a method comprising the steps of reacting by adding amylosucrase (EC 2.4.1.4) to a substrate containing sucrose; And, after the addition reaction of the amylo sucralase (EC 2.4.1.4) for 3 to 12 hours, glycogen branching enzyme (EC 2.4.1.18) is sequentially added to the substrate to react.

본 발명에서 사용한 아밀로수크라아제 및 글리코겐 가지화 효소는 각각의 효소의 특징이 결합된 시너지 효과를 발휘하는데, 글리코겐 가지화 효소는 아밀로수크라아제가 포도당을 전이시켜줄 수 있는 새로운 활성부위를 형성해 주어 아밀로수크라아제가 자당을 가수분해하는 속도를 빠르게 할 수 있으며, 반응 후의 생산물은 분지사슬의 길이가 길어져 인체 내 효소로써는 분해가 될 수 없는 난소화성 말토덱스트린으로 형성된다(도 1 참조).Amylosucrase and glycogen branching enzyme used in the present invention exert a synergistic effect combined with the characteristics of each enzyme, glycogen branching enzyme is a new active site that amylosucrase can transfer glucose By forming it, the rate of hydrolysis of sucrose by amylosukraase can be increased, and the product after the reaction is formed with an indigestible maltodextrin which cannot be degraded by enzymes in the human body due to the length of the branched chain (see FIG. 1). ).

본 발명은 자당을 함유한 기질에 아밀로수크라아제를 첨가하여 반응시킨 후, 3~12시간 후에 글리코겐 가지화 효소를 순차적으로 첨가하는데, 아밀로수크라아제를 첨가한 후 3시간 미만에 첨가할 경우나 시간을 초과한 후 첨가할 경우에는, 아밀로수크라아제에 의한 α-1,4 글루칸의 형성이 원활히 이루어지지 않아 글리코겐 가지화 효소로 인한 새로운 분지사슬(α-1,6 결합)의 형성도 효율적으로 이루어지지 않기 때문에 난소화성 말토덱스트린의 생산 수율이 떨어진다.In the present invention, after adding and reacting amylosucrase to the substrate containing sucrose, the glycogen branching enzyme is sequentially added after 3 to 12 hours, and is added within 3 hours after adding amylosucrase. In case of addition or overtime, the formation of α-1,4 glucan by amylosucrase is not performed smoothly, resulting in new branched chain (α-1,6 binding) due to glycogen branching enzyme. The yield of indigestible maltodextrin is lowered because the formation of is not efficient.

한편, 아밀로수크라아제의 작용에 의해 자당으로부터 분리되어 나온 포도당들은 아밀로수크라아제에 의해 상호 결합하여 α-1,4 글루칸을 생산할 수 있기 때문에, 본 발명의 난소화성 말토덱스트린의 제조방법에 있어서, 기질은 별도의 α-1,4 결합을 가지는 수용체가 없어도 무방하나, 반응 시간의 단축을 위해 바람직하게는 α-1,4 결합을 가지는 수용체가 기질에 포함되어 있는게 좋은데, α-1,4 결합을 가지는 수용체의 일 예로는 아밀로오스가 있다. On the other hand, since the glucose separated from sucrose by the action of amylosucrase can be combined with amylosucrase to produce α-1,4 glucan, the method for producing the indigestible maltodextrin of the present invention In the substrate, there may be no receptor having a separate α-1,4 bond, but in order to shorten the reaction time, it is preferable that the substrate contains a receptor having α-1,4 bond. An example of a receptor having 4 binding is amylose.

또한, 본 발명의 난소화성 말토덱스트린의 제조방법에 있어서, 반응은 30℃에서 수행하는 것이 좋은데, 이 범위에서 난소화성 말토덱스트린의 생산 수율이 다른 온도에 비해 우수하기 때문이다. In addition, in the method for producing the indigestible maltodextrin of the present invention, the reaction is preferably performed at 30 ° C., because the production yield of the indigestible maltodextrin is superior to other temperatures in this range.

한편, 본 발명의 난소화성 말토덱스트린의 제조방법에 있어서, 아밀로수크라아제(EC 2.4.1.4)는, 일 예로 나이세리아 폴리사카리아(Neisseria Polysaccharea)에서 유래한 것일 수 있고, 글리코겐 가지화 효소(EC 2.4.1.18)는, 일 예로 시네코시스티스(Synechocystis sp. PCC6803) 균주에서 유래한 것일 수 있다. On the other hand, in the method of producing the indigestible maltodextrin of the present invention, amylosucrase (EC 2.4.1.4), for example, may be derived from Neisseria Polysaccharea , glycogen branching enzyme (EC 2.4.1.18), for example, may be derived from Synechocystis sp. PCC6803 strain.

본 발명은 반응 기질에 아밀로수크라아제를 첨가한 후, 3~12시간 경과 후 순차적으로 글리코겐 가지화 효소를 첨가함으로써, RS3 형태의 난소화성 말토덱스트린을 고 수율로 생산할 수 있다. In the present invention, after the addition of amylosucrase to the reaction substrate, the glycogen branching enzyme is sequentially added after 3 to 12 hours, thereby producing an indigestible maltodextrin of RS3 in high yield.

또한, 본 발명은 반응공정이 화학적 혹은 물리적 처리 공정이 아닌 생촉매인 효소를 이용한 공정이기 때문에 안전성이 확보된 난소화성 말토덱스트린을 생산할 수 있는 효과가 있다. In addition, the present invention has the effect of producing a safe indigestible maltodextrin because the reaction process is a process using an enzyme that is a biocatalyst rather than a chemical or physical treatment process.

이하, 본 발명의 내용을 하기 실시예를 들어 더욱 상세히 설명하지만, 본 발명의 권리범위가 하기 실시예에만 한정되는 것은 아니고, 그와 등가의 기술적 사상의 변형까지를 포함한다.Hereinafter, the content of the present invention will be described in more detail with reference to the following examples, but the scope of the present invention is not limited only to the following examples, and includes modifications of equivalent technical ideas.
