Description

5'-구아닐산 2나트륨/5'-이노신산 2나트륨의 혼합결정을 제조하는 방법Method for preparing a mixed crystal of 5'-sodium guanylic acid / 5'-inosinoic acid sodium

본 발명은 5'-구아닐산 2나트륨/5'-이노신산 2나트륨의 비가 1.0-1.05인 수용액 내에서 5'-구아닐산 2나트륨(이하 GMP 2Na로 약칭)과 5'-이노신산 2나트륨(이하 IMP 2Na로 약칭)이 1:1로 혼합된 결정을 제조하는 방법에 관한 것이다.The present invention relates to a sodium 5'-guanylate (hereinafter abbreviated as GMP 2Na) and a 5'-inosinate (hereinafter referred to as IMP 2Na) in an aqueous solution in which the ratio of 5'-disodium guanylate / 5'-inosinic acid dibasic is 1.0-1.05. Abbreviated) in a 1: 1 manner.

일반적으로 GMP 2Na와 IMP 2Na가 1:1로 혼합된 경우에는 맛의 강도가 유리하기 때문에 GMP 2Na와 IMP 2Na를 각각 별도로 제조하여 혼합 사용하고 있으나, 결정화합에 있어 IMP 2Na는 용이한 반면에 GMP 2Na는 곤란한 문제점이 있음은 물론, 이들을 혼합하여 사용할 경우에는 별도의 혼합공정을 거쳐야하는 번거로움이 있었다.In general, when GMP 2Na and IMP 2Na are mixed 1: 1, GMP 2Na and IMP 2Na are separately prepared and used because of the strength of taste, but IMP 2Na is easy in crystallization, whereas GMP 2Na has a difficult problem, of course, when using a mixture of these, there was a need to go through a separate mixing process.

한편, 이와같은 문제점을 개선하기 위한 일특공개소 50-160295에는 GMP 2Na와 IMP 2Na를 혼합 결정으로 제조하면 분리성이 향상되고 품질면에서도 우수한 제품을 얻을 수 있다고 밝힌바 있다.On the other hand, in one special publication 50-160295 to improve such a problem, the GMP 2Na and IMP 2Na prepared by mixing crystals have improved the separation and excellent in terms of quality can be obtained.

이러한 GMP 2Na.IMP 2Na 혼합결정을 제조하는 종래의 방법으로는 GMP 2Na/IMP 2Na의 비가 1.2-2.6인 수용액내에서 GMP 2Na와 IMP 2Na가 1:1로 혼합된 결정을 제조하는 일특공개소 53-124686이 있으나, 여기에서는 수용액중 GMP 2Na와 IMP 2Na의 비가 높아 1:1의 비로 혼합된 결정을 취득하기가 어려울뿐만 아니라, 단순히 냉각정석만으로 결정을 석출, 취득하므로서 분리모액중에 GMP 2Na와 IMP 2Na의 함유농도가 높아 제품의 회수율이 떨어지고 한편으로는 발생된 모액을 재정제 회수할 경우 설비의 비대 및 부재료의 사용이 증가하여 제조원가면에서 불리한 단점이 있었다. 따라서 본 발명자들은 종래방법의 문제점을 개선하기 위하여 연구 검토하던중, GMP 2Na/IMP 2Na의 비가 1.0-1.05인 GMP 2Na.IMP 2Na혼합수용액을 40℃에서 친수성유기 용매인 메탄올 또는 에탄올을 최종 정석완료액 알코올농도 60%까지 첨가하는데 있어서, 총알코올 사용량의 5%를 30분간에 걸쳐 서서히 첨가하고, GMP 2Na.IMP 2Na 혼합결정이 석출되기 시작하는 시점에서 10분간 숙성하여 결정의 균일화를 행한 다음, 나머지 95%분의 알코올을 첨가하므로써 GMP 2Na.IMP 2Na의 비가 1:1인 주상형의 결정을 용이하게 취득 할수 있음을 알았다.Conventional methods for preparing such GMP 2Na.IMP 2Na mixed crystals include one special public place for producing a 1: 1 mixed crystal of GMP 2Na and IMP 2Na in an aqueous solution having a ratio of GMP 2Na / IMP 2Na of 1.2-2.6. -124686, but the high ratio of GMP 2Na and IMP 2Na in aqueous solution makes it difficult to obtain mixed crystals in a ratio of 1: 1, and also precipitates and acquires crystals by cooling crystallization alone, thereby GMP 2Na and IMP in the separated mother liquor. The high concentration of 2Na lowers the recovery rate of the product. On the other hand, refining and recovering the mother liquor has an disadvantage in terms of manufacturing cost due to an increase in the size of equipment and the use of subsidiary materials. Therefore, the present inventors completed the final crystallization of the GMP 2Na.IMP 2Na mixed aqueous solution having a ratio of GMP 2Na / IMP 2Na of 1.0-1.05 at 40 ° C. while studying and researching to improve the problems of the conventional method. To add up to 60% of the liquid alcohol concentration, 5% of the total alcohol consumption is slowly added over 30 minutes, and aged for 10 minutes when the GMP 2Na.IMP 2Na mixed crystal starts to precipitate, to homogenize the crystals, By adding the remaining 95% of the alcohol, it was found that the columnar crystals having a ratio of GMP 2Na.IMP 2Na can be easily obtained.

일반적으로 IMP 2Na는 결정화가 용이하기 때문에 IMP 2Na 수용액 상태에서 감압농축하면 간단히 결정을 얻을 수 있으나, GMP 2Na는 점성이 높아 감압농축만으로는 결정상태로 얻기가 불가능한 문제점이 있다. 그러므로 GMP 2Na의 결정화 방법으로는 GMP 2Na의 점성을 약화시키면서 용해도를 낮추어 결정을 석출시키는 아세톤, 알코올등 친수성유기용매를 이용한 방법등이 공업적으로 널리 알려져 있으나, 이러한 방법에 서는 농도, PH, 교반속도, 시딩 방법 및 시기, 액성등 여러가지 정출조건을 모두 충족시켜야만 상품으로서의 가치가 있는 제품을 얻을 수 있는 단점이 있었다.In general, since IMP 2Na is easily crystallized, crystals can be easily obtained by concentrating under reduced pressure in an aqueous solution of IMP 2Na. However, GMP 2Na has a high viscosity, which makes it impossible to obtain crystals by concentrating only under reduced pressure. Therefore, the crystallization method of GMP 2Na is known industrially using hydrophilic organic solvents such as acetone, alcohol, etc. to precipitate crystals by lowering the solubility while weakening the viscosity of GMP 2Na, but in this method, concentration, PH, stirring It is disadvantageous to obtain a product that is valuable as a product only when all the various conditions of settlement such as speed, seeding method, timing, and liquidity are satisfied.

이에 반하여 본 발명에서와 같은 GMP 2Na, IMP 2Na 혼합 결정을 제조할 경우에는 GMP 2Na를 석출시키는 수단으로 친수성유기용매만을 이용, GMP 2Na·IMP 2Na 혼합결정을 제조 할수 있으므로 IMP 2Na 제조시 소요되는 별도의 감압 농축설비가 필요치 않으므로 공정이 간소화됨은 물론, 에너지를 절약할 수 있는 잇점이 있고, 결정성이 나쁜 조 GMP 2Na결정도 결정성이 좋은 조 IMP 2Na 결정과 수용액 상태에서 정출되어 결정성이 양호한 GMP 2Na·IMP 2Na의 혼합결정으로 제조할 수 있는 잇점이 있다.On the contrary, when manufacturing GMP 2Na and IMP 2Na mixed crystals as in the present invention, GMP 2Na and IMP 2Na mixed crystals can be prepared using only hydrophilic organic solvents as a means of precipitating GMP 2Na. The process is simplified as well as energy saving is not necessary because the pressure reducing and condensation concentration system is not necessary. The crude GMP 2Na crystals with poor crystallinity are also crystallized in the crystallized crude IMP 2Na crystal and aqueous solution, and have good crystallinity. There is an advantage that can be produced by a mixed crystal of GMP 2Na IMP 2Na.

또한 GMP 2Na·IMP 2Na 혼합결정의 제조에 있어서, 그 혼합비가 1:1이 가장 바람직한 것은 일반 조미료로서 사용되는 GMP 2Na, IMP 2Na는 맛의 상승효과를 높이고 경제적인 가격을 유지하기 위해 MSG와 코팅된 복합 조미료로 시판되고있어 GMP 2Na.IMP 2Na의 비가 1:1로 되지 않는 제품으로는 등량의 GMP 2Na와 IMP 2Na가 함유된 복합조미료를 제조 할 수 없기 때문이다.In addition, in the preparation of GMP 2Na and IMP 2Na mixed crystals, the mixing ratio of 1: 1 is most preferable. GMP 2Na and IMP 2Na, which are used as general seasonings, are coated with MSG in order to enhance taste synergy and maintain economic price. It is commercially available as a complex seasoning, and it is impossible to produce a complex seasoning containing an equivalent amount of GMP 2Na and IMP 2Na with a product that does not have a 1: 1 ratio of GMP 2Na.IMP 2Na.

이에 대하여 본 발명자 등은 GMP 2Na/IMP 2Na의 수용액 비를 1.0-1.05로 할 경우 GMP 2Na·IMP 2Na의 혼합비가 1:1인 주상형의 결정을 제조 할 수 있음을 발견하였다.On the other hand, the inventors have found that when the aqueous solution ratio of GMP 2Na / IMP 2Na is 1.0-1.05, crystals of columnar form having a mixing ratio of GMP 2Na.IMP 2Na of 1: 1 can be prepared.

표1은 수용액 중에서 GMP 2Na/IMP 2Na의 비에 대한 최종 혼합결정중 GMP 2Na 및 IMP 2Na의 함량을 나타내는 것이다.Table 1 shows the contents of GMP 2Na and IMP 2Na in the final mixed crystal to the ratio of GMP 2Na / IMP 2Na in aqueous solution.

[표 1]TABLE 1

Figure kpo00001
Figure kpo00001

표1의 기재에서와 같이 GMP 2Na/IMP 2Na의 비가 1.05이상인 경우에는 혼합결정 중 GMP 2Na의 함량이 IMP 2Na함량 보다 높아 소정의 목적을 달성할 수 없어 본 발명에서는 수용액중 GMP 2Na/IMP 2Na의 비를 1.0-1.05로 제한 하였다. 여기에서 1.05의 비까지 가능한 것은 친수성 유기용매에 대한 GMP 2Na의 용해도가 IMP 2Na의 용해도 보다 약간 높아 모액쪽으로 이행되는 GMP 2Na의 량이 다소 증가하는 경향이 있기 때문이다.As described in Table 1, when the ratio of GMP 2Na / IMP 2Na is 1.05 or more, the content of GMP 2Na in the mixed crystal is higher than the content of IMP 2Na, and thus it is impossible to achieve a predetermined purpose. The ratio was limited to 1.0-1.05. The ratio of 1.05 is possible because the solubility of GMP 2Na in hydrophilic organic solvents is slightly higher than the solubility of IMP 2Na, which tends to increase the amount of GMP 2Na towards the mother liquor slightly.

또한 종래의 방법에서는 GMP 2Na·IMP 2Na의 수용액 상태에서 단순히 냉각 정석만으로 결정을 석출, 취득하였으나, 용해도가 20℃에서는 GMP 2Na23.6g/물 100g, IMP 2Na가 14.3g/물 100g이고 5℃에 서는 GMP 2Na가 19.0g/100g. IMP 2Na가 8.7g/물 100g으로 GMP 2Na가 높아(일본 화학조미료 114 및 117면 참조)제품의 회수율이 떨어지고, 모액중에 포함된 GMP 2Na·IMP 2Na를 회수하기 위해서는 정제 설비의 비대, 부재료 사용증가등 제조원가면에서 매우 불리한 단점과 최종정석 완료후에도 결정이 균일치 못함은 물론, 무정형까지도 함유하고 있어 결정분리가 곤란한 단점이 있었다.In the conventional method, crystals were precipitated and obtained by simply cooling crystallization in an aqueous solution of GMP 2Na and IMP 2Na. However, at 20 ° C, GMP 2Na23.6g / water 100g and IMP 2Na were 14.3g / water 100g and at 5 ° C. GMP 2Na is 19.0g / 100g. GMP 2Na is high with 8.7g / 100g of water (see Japanese seasonings 114 and 117) .The recovery rate of the product is lowered. It is very disadvantageous in terms of manufacturing cost and crystallization even after the final crystallization, as well as amorphous, it also has a disadvantage that the crystal separation is difficult.

따라서 본 발명자들은 이미 널리 알려진 매탄올, 에탄올 등의 친수성 유기용매를 사용하여 알코올을 참가함에 있어서, 처음 부터 알코올을 급격히 첨가할 경우에는 최초에 IMP 2Na만이 석출 되므로 GMP 2Na는 결정성이 나빠서 상품으로서의 가치가 저하되는 등 결정성이 차이가 있음에 유의하여 알코올 첨가방법에 대하여 인구를 거듭한 결과, 최초 총 알코올 사용량의 5%(최종정석 완료액 알코올농도 60%기준)를 30분에 걸쳐 첨가할 경우에는 GMP 2Na·IMP 2Na의 혼합결정이 동시에 석출되며 그 시점에서약 10분간 숙성하여 결정을 균일화한 후 남은 95%분의 알코올을 3시간 동안 첨가하면 분리성이 아주 양호하고 상품으로서의 가치가 높은 GMP 2Na.IMP 2Na의 혼합결정을 얻을 수 있음을 발견하고 본 발명을 완성하였다.Therefore, the present inventors participate in alcohol using a well-known hydrophilic organic solvent such as methanol, ethanol, and when the alcohol is rapidly added from the beginning, only IMP 2Na is first precipitated, so GMP 2Na is poor in crystallinity. As a result of repeated populations for the method of adding alcohol, taking into account the difference in crystallinity such as deterioration in value, 5% of the initial total alcohol consumption (based on 60% of final crystallized alcohol concentration) can be added over 30 minutes. In this case, mixed crystals of GMP 2Na and IMP 2Na are precipitated at the same time. After aging for about 10 minutes at that point, the crystals are homogenized and the remaining 95% of alcohol is added for 3 hours. The present invention has been completed by discovering that a mixed crystal of GMP 2Na.IMP 2Na can be obtained.
