Abstract

There are more than 2000 minerals on earth, and it has been implemented in various fields such as environment, architecture, livestock, chemistry, pharmaceuticals. Clay minerals are considered that they can change the physical and chemical properties through the adsorption and release of metal ions. Although domestic deposit of non-metallic mineral resources is approximately ninety-six billion tons, its application is limited and has hardly been used in high value-added industries involved in medicine, medical supplies, and functional food materials. Bentonite and zeolite are already used for cosmetic purposes and also used in living goods and packing materials. However, direct application to the food industry is relatively very rare. Since records regarding the intake of minerals for foods and medicines are found in the old literatures, the utilization of non-metallic minerals as food materials appears to be highly profitable. According to the trends in patent research for food and mineral resources, the company plays a main role for the development of the food containing non-metallic minerals in USA, and the trends confirms that this industry is emerging. Here, we provided the information about domestic and foreign patent trend for food industries involved in mineral resources and the application of mineral resources in the food industries. We also covered the domestic regulation regarding usage of mineral resources in food, and proposed domestic application plan for food production using mineral resources in the future.

지구상에는 2000종 이상의 광물이 존재하고 있으며 환경, 건축, 축산, 화학, 의약 등의 다양한 분야에서 활용되고 있다. 그 중 점토광물은 흡착과 방출을 통해 물리 화학적인 성질이 변할 수 있는 특징이 있다. 국내 비금속 광물자원의 매장량은 약 96억 톤으로 그 자원 효용이 높은데 반해 고부가가치화를 이루지 못하고 있는 실정이다. 또한 벤토나이트와 제올라이트를 이용한 제품들이 화장품과 생활용품, 포장재 등에 일부 사용되고 있지만 잠재적인 가치 측면에서 무한한 가능성을 지닌 식품산업에 활용된 사례는 사실상 전무하다. 광물자원에 대한 식품/약용으로의 섭취기록은 이미 오래 전부터 문헌상으로 존재하고 있으며, 국내 매장량이 높은 자원임을 감안할 때 식품 소재로서의 활용가치는 상당하리라 생각된다. 점토광물의 특허 동향 조사를 통해 미국, 유럽을 비롯한 세계 각국이 기업체를 중심으로 광물자원을 식품산업에 적용하기 위한 기술을 개발 중이며, 관련 산업이 성장시기에 있다는 것을 확인할 수 있었다. 따라서 본 논문에서는 국내외 광물자원 관련 식품산업분야 특허 동향과 광물자원의 식품산업분야 이용 및 규제 현황에 관한 정보를 제공하고, 이를 바탕으로 향후 광물자원을 식품분야에 어떻게 활용할 지에 대한 적용 방안을 제시하고자 한다.
