Determination of Microplastics in Omega-3 Oil Supplements

오메가-3 오일 보충제의 미세플라스틱 측정

 

Abstract

Microplastics (MPs) are ubiquitous in the environment, posing a threat to ecosystems and causing increasing concerns regarding their impacts on the human body through exposure. However, there has been limited research on the presence of MPs in functional foods, despite them being consumed for health improvement. This study aimed to investigate MP occurrence in various omega-3 oils and oil products in the Korean market and its relation to the source of raw material or manufacture. MPs were investigated in omega-3 capsules and raw oil, sourced from both plant-based (PB) and animal-based (AB) sources. We developed a method of direct filtration with acetone washing for collecting and characterizing MPs larger than 5 μm using micro-Raman spectroscopy. The average number of MPs by mass was found to be 1.2 ± 1.7 MPs/g for PB raw oil, 2.2 ± 1.7 MPs/g for AB raw oil, 3.5 ± 3.9 MPs/g for PB capsule oil, and 10.6 ± 8.9 MPs/g for AB capsule oil. Polypropylene and polyethylene terephthalate were the major MP species (83–95%) found in omega-3 oil. The proportions based on size range remained consistent across all groups, with a trend of being detected at higher rates as the size decreased. The results reveal that the main reason for the MP contamination of omega-3 oil is not the source of raw material but the manufacturing and packaging process.

 

미세플라스틱(MP)은 환경 어디에나 존재하며 생태계에 위협을 가하고 노출을 통해 인체에 미치는 영향에 대한 우려가 커지고 있습니다. 그러나 건강 증진을 위해 섭취되고 있음에도 불구하고 기능성 식품에 MP가 존재하는지에 대한 연구는 제한적이었습니다. 본 연구의 목적은 한국 시장의 다양한 오메가-3 오일 및 오일 제품에서 MP 발생과 원료 공급원 또는 제조와의 관계를 조사하는 것입니다. MP는 식물성(PB) 및 동물성(AB) 공급원 모두에서 공급되는 오메가-3 캡슐과 원유에서 조사되었습니다. 우리는 마이크로 라만 분광법을 사용하여 5μm보다 큰 MP를 수집하고 특성화하기 위해 아세톤 세척을 통한 직접 여과 방법을 개발했습니다. 질량 기준 평균 MPs 수는 PB 원유의 경우 1.2 ± 1.7 MPs/g, AB 원유의 경우 2.2 ± 1.7 MPs/g, PB 캡슐 오일의 경우 3.5 ± 3.9 MPs/g, 10.6 ± 8.9 MPs/g인 것으로 나타났습니다. g AB 캡슐 오일의 경우. 폴리프로필렌과 폴리에틸렌 테레프탈레이트는 오메가-3 오일에서 발견되는 주요 MP 종(83~95%)이었습니다. 크기 범위에 따른 비율은 모든 그룹에서 일관되게 유지되었으며 크기가 감소함에 따라 더 높은 비율로 감지되는 경향이 있습니다. 연구 결과, 오메가-3 오일의 MP 오염의 주요 원인은 원료 공급원이 아닌 제조 및 포장 과정에 있는 것으로 나타났습니다.
