Description
본 발명은 음이온 교환수지를 이용하여 튀김유 등의 식용유지를 탈취, 탈산하여 유지의 품질을 개선하는 방법에 관한 것으로 구체적으로는 강염기성 또는 약염기성 음이온 교환수지를 사용하거나 상기 음이온교환수지와 활성탄을 사용하여 유지를 처리함으로써 유지 내에 존재하는 냄새와 유리지방산을 제거하여 유지의 안정성과 제품의 상미기간을 증대시키는 방법이다.The present invention relates to a method of improving the quality of fats and oils by deodorizing and deoxidizing edible oils such as frying oil using anion exchange resins. Specifically, strong or weak base anion exchange resins are used or the anion exchange resins and activated carbons are used. It is a method to increase the stability of oil and fat of the product by removing the odor and free fatty acid present in the oil by treating the oil.
통상, 식용유지는 원유로부터 탈검, 탈산, 탈취 및 탈수, 분별 등의 과정을 거쳐 제조된다. 그러나, 식용유지는 보관 중, 또는 가공공정 중에 여러 인자들에 의해 가수분해가 일어나 유리지방산이 생성되고, 생성된 유리지방산은 산화, 분해, 중합 등의 반응을 거쳐 냄새물질 및 독성물질을 생성하게 된다. 따라서, 식품에 사용되는 유지는 그 초기 산가(또는 초기 유리지방산 함량)가 엄격히 규제되고 있다.Typically, edible oils and fats are prepared from crude oil through degumming, deoxidation, deodorization and dehydration, and fractionation. However, edible oils are hydrolyzed by various factors during storage or processing to produce free fatty acids, and the produced free fatty acids undergo oxidative, decomposition and polymerization reactions to produce odorous and toxic substances. . Therefore, the initial acid value (or initial free fatty acid content) of fats and oils used in food is strictly regulated.
식용유지는 특히 고온에서 수분과의 접촉에 의하여 가수분해되어 유리지방산을 생성하며, 생성된 유리지방산은 유지의 가수분해를 촉진시켜 식용유지의 수명을 단축시킬 뿐만 아니라 자신이 열중합, 열산화를 일으켜 착색물질, 냄새물질 및 산화생성물을 형성한다. 따라서, 가능하다면 작업중 또는 작업이 끝난 후 지방산을 제거할 필요가 있다.Edible oils are hydrolyzed by contact with moisture, especially at high temperatures, to produce free fatty acids. The free fatty acids promote hydrolysis of oils and fats, which shortens the lifespan of edible oils, and also causes thermal polymerization and thermal oxidation. Forms coloring matter, odorants and oxidation products. Therefore, if possible, it is necessary to remove fatty acids during or after the operation.
우선 식용유지의 가수분해 정도를 낮추어 유리지방산의 생성을 억제하는 방법으로는 가공공정중 유지의 과열을 방지하거나 가공하고자 하는 식용유지의 수분을 가능한 낮게 하거나 또는 카포크유의 사이크로프로펜산을 사용하는 방법 등이 있다.First of all, as a method of reducing the degree of hydrolysis of edible fats and oils to suppress the production of free fatty acids, it is possible to prevent overheating of fats and oils in the processing process, to reduce the moisture of edible fats to be processed as low as possible, or to use cyclopropene acid of capok oil. Method and the like.
또한, 생성된 지방산을 제거하는 방법으로는 튀김 등의 작업종료 후에 수산화알루미늄 겔 또는 염기성 활성 알루미나에 유리지방산을 흡착시켜 제거하는 방법 등이 있다.As a method of removing the generated fatty acid, there is a method of adsorbing and removing free fatty acid on an aluminum hydroxide gel or basic activated alumina after completion of work such as frying.
그러나, 상기의 방법들은 유리지방산 제거 효율이 낮기 때문에 완전한 처리 효과를 기대하기가 어렵다는 단점이 있다. 이를 해결하기 위하여 사용되는 방법으로 식용유지의 처리시에 수산화나트륨을 이용하여 처리하는 방법이 있다. 그러나, 이 방법을 사용하기 위해서는 매우 큰 처리장치가 필요하고, 에너지 비용이 많이 수반되며, 작업조건도 까다로와 작업자의 안전에도 유의해야 하는 등 여러 가지 문제가 존재한다.However, the above methods have a disadvantage in that it is difficult to expect a complete treatment effect because of low free fatty acid removal efficiency. As a method used to solve this problem, there is a method of treating with sodium hydroxide during the treatment of edible oils and fats. However, the use of this method requires a very large processing device, requires a lot of energy costs, has a lot of working conditions, and requires attention to the safety of the worker.
이에 본 발명자들은 상기와 같은 문제점을 해결하기 위하여 노력하던 중, 음이온 교환수지를 이용하여 유지를 처리하는 경우, 종래의 수산화알루미늄 겔 또는 염기성 활성알루미나를 이용하여 처리하는 경우에 나타나는 낮은 지방산 제거 효율 문제를 개선할 수 있고, 수산화나트륨을 사용할 경우에 문제되는 높은 설비 비용과 고에너지 비용 및 안전성 문제를 해결할 수 있어, 간편하고 낮은 처리 비용으로 유지를 개선할 수 있다는 사실을 알아내어 본 발명을 완성하였다.Accordingly, the present inventors, while trying to solve the above problems, when treating fats and oils using anion exchange resin, low fatty acid removal efficiency problems appearing when treating with conventional aluminum hydroxide gel or basic activated alumina The present invention has been completed by finding out that it is possible to improve the maintenance cost and improve the maintenance cost with a simple and low treatment cost, which can solve the high equipment cost, high energy cost and safety problems that are encountered when using sodium hydroxide. .

상기 목적을 달성하기 위하여 본 발명에서는 식용유지를 음이온 교환수지가 충진된 된 탑을 통과시키거나 식용유지에 음이온 교환수지를 직접 첨가하여 식용유지 중의 유리지방산을 제거하는 방법을 제공한다.In order to achieve the above object, the present invention provides a method for removing free fatty acids in edible oil by passing an edible oil through a tower filled with anion exchange resin or by directly adding an anion exchange resin to the edible oil.

<제조예 1>에 의하여 활성화된 다공성 강염기성 음이온 교환수지 50ml를 내경 25mm 칼럼에 채우고, 산가가 1.2 내외인 식용 유지를 평균유속 1.2 ml/min이 되게 흘려주었다. 수지량에 대한 식용유지 처리량(Bed Volume)에 대한 산가 변화를 표 5에 나타내었다.50 ml of the porous strong basic anion exchange resin activated by <Production Example 1> was filled in a 25 mm inner diameter column, and an edible oil having an acid value of about 1.2 was flowed at an average flow rate of 1.2 ml / min. Table 5 shows the acid value change of the edible oil and fat (Bed Volume) with respect to the resin amount.
<실시예 4> 및 <실시예 5>에서 보듯이 <실시예 1>과 같은 양의 다공성 강염기성 음이온 교환수지로 그 효과유지를 사용하였지만 그 수지가 충진된 탑의 내경과 식용유지의 평균 유속에 따라 그 유지의 탈산 효과가 달라짐을 알 수 있다. 즉, 식용유지와 다공성 강염기성 음이온 교환수지의 접촉시간이 길어질수록 유지의 탈산 효과가 커짐을 알 수 있다.As shown in <Example 4> and <Example 5>, the effect oil was used as the porous strong basic anion exchange resin in the same amount as in <Example 1>, but the inner diameter of the resin-filled tower and the average flow rate of the edible oil were It can be seen that depending on the deoxidation effect of the fat. In other words, the longer the contact time between the edible oil and the porous strong basic anion exchange resin, the greater the deoxidation effect of fats and oils.
<실시예 6> 다공성 강염기성 음이온 교환수지와 입상 활성탄을 이용한 유지의 처리Example 6 Treatment of Oils and Fats Using Porous Strong Basic Anion Exchange Resin and Granular Activated Carbon
<제조예 1>에 의하여 활성화된 다공성 강염기성 음이온 교환수지 40ml와 입상 활성탄 10ml를 내경 34mm 칼럼에 채우고, 산가가 1.2 내외인 식용 유지를 평균유속 3.5 ml/min이 되게 흘려주었다. 수지량에 대한 식용유지 처리량(Bed Volume)에 대한 산가 변화를 표 6에 나타내었다.40 ml of porous strong base anion exchange resin and 10 ml of granular activated carbon activated by <Production Example 1> were filled in a 34 mm column, and an edible oil having an acid value of about 1.2 was flowed to an average flow rate of 3.5 ml / min. Table 6 shows the acid value change of the edible oil and fat (Bed Volume) to the resin amount.
상기 표에서 보듯이 활성탄을 혼합하여 유지를 처리한 경우, 단위부피당 처리용량이 증가함에 따라 다공성 강염기성 음이온 교환수지만으로 유지를 처리한 경우에 비하여는 약간의 차이가 나타나지만, 처리 후의 유지의 산가는 식용유지에 비하여 현저히 낮아짐을 알 수 있었다. 즉, 유지의 탈산 공정 시에 다공성 강염기성 음이온 교환수지만을 사용하는 외에 활성탄을 혼합하여 사용하는 경우에도 효과적으로 식용유지로부터 유리지방산을 제거할 수 있음을 알 수 있다.As shown in the table above, when the fats and oils were treated by mixing activated carbon, there was a slight difference compared to the case where the fats and fats were treated with only porous strong basic anion exchange resin as the treatment capacity per unit volume increased. It can be seen that significantly lower than the edible oil and fat. In other words, it can be seen that free fatty acids can be effectively removed from the edible oil and fat even in the case of using activated carbon in addition to using only porous strong base anion exchange resin in the deoxidation process of fats and oils.

건조 상태의 다공성 강염기성 음이온 교환수지를 처리하고자 하는 유지에 대하여 0.5%(W/W)가 되게 직접 첨가한 다음, 교반하면서 시간에 따른 유지의 산가를 측정하여 표 8에 나타내었다.The porous strong basic anion exchange resin in the dry state was added directly to 0.5% (W / W) to the fat to be treated, and the acid value of the fat and fat was measured as shown in Table 8 while stirring.
이상에서 살펴본 봐와 같이, 본 발명은 음이온 교환수지 또는 음이온 교환수지와 활성탄이 혼합되어 충진된 탑을 이용하거나 식용유지에 음이온 교환수지를 직접 첨가하여 식용유지 중의 유리지방산을 제거하는 방법에 관한 것으로서, 기존 방법의 낮은 지방산 제거효율, 높은 설비비용 및 안전성 문제 등을 해결하여, 간편하고 저렴한 처리비용으로 식용유지 중의 유리지방산을 높은 효율로 제거할 수 있는 장점이 있다.As described above, the present invention relates to a method for removing free fatty acids in edible oil by using an anion exchange resin or a tower filled with anion exchange resin and activated carbon, or by adding an anion exchange resin directly to an edible oil. In addition, by solving the low fatty acid removal efficiency, high equipment cost and safety problems of the existing method, there is an advantage that can remove the free fatty acid in the edible oil with high efficiency at a simple and low processing cost.
