Abstract

The proportion of plant-based meat alternative (PBMA) consumers has recently increased in Korea. This is due to several reasons including protecting the environment, satisfying preferences, maintaining health, and improving eating habits. Accordingly, many companies produce and sell alternative meat using various materials. Alternative meats are classified into plant (such as soybeans and wheat), seaweed, insect, and cultured meats, depending on the raw materials used in manufacturing. PBMA is sold after undergoing processes such as grinding, seasoning, and molding. Therefore, monitoring the presence of any hazardous elements during this process is essential. Accordingly, in this study, we analyzed the harmful components of nine domestically distributed PBMA that are most easily accessible to consumers. After extracting fat from the samples and analyzing the rancidity level, samples F, G, and I were highly rancid. Trace amounts of aflatoxin were detected in samples A and B, but confirmed to be within the range. Cd and Pb were not detected in any sample. We hope that this study will help establish methods to ensure the safety of domestically sold PBMA.

국내에서 제조되어 유통되는 식물성 대체육을 대상으로 일반성분(수분, 단백질, 지방), 지방의 산패도, 지방산의 조성, 아플라톡신, 중금속 함량을 분석하였다. 그 결과 한번 익힌 후 건조된 형태의 식물성 대체육보다 익히지 않고 수분이나 지방에 의해 성형과정을 거친 냉동제품에서 상대적으로 많은 양의 지방을 함유하고 있음을 확인할 수 있었다. 조지방 함량이 1 g을 넘는 시료를 대상으로 지방의 산패도(산가, 과산화물가)를 측정했다. 그 결과 일부 시료에서 높은 산가 및 과산화물가가 측정되었으나 식품공전상에 대체육에 대한 정확한 분류가 되어있지 않아 산패도에 대한 안전성을 판단하기 위한 규격이 필요해 보인다. 가스크로마토그래피를 사용하여 지방산 조성을 분석한 결과 대부분은 불포화지방산이 차지하고 있지만, 일부 포화지방산의 함량이 높은 시료가 있었다. 포화지방산 및 불포화지방산의 함량이 높은 식물성 대체육을 식물성 유지를 사용하여 가열조리를 거쳐 섭취하게 된다면, 많은 양의 지방을 섭취하게 될 수 있음을 예측할 수 있다. 또 가스크로마토그래피를 사용한 지방산 분석법을 통해 식물성대체육에 동물 유래 지질이 함유되어있지 않음을 확인할 수 있었다. 이는 이후에 식물성 대체육에 대한 영양표시성분 및 실제성분의 대조 시에 활용될 수 있음을 시사한다. 식물성 대체육에 대하여 아플라톡신을 분석한 결과 현재 식품공전에 제시된 농산물 중 아플라톡신 기준규격에 대하여 적합인 수준이나 미량 검출되는 것을 확인하였다. 중금속의 분석 결과 모두 불검출이었으나 환경요인 및 원재료에 따라 중금속의 오염이 의심될 시에 중금속 분석을 진행할 수 있을 것으로 판단된다. 이러한 실험결과를 통해 국내에 유통되고 있는 일부 식물성 대체육에 대한 안전성을 확인하였으나 산가, 과산화물가, 아플라톡신, 중금속은 대체육에 대하여 구체적인 분류 및 적합 규격이 마련되어 있지 않아 적합 판정시에 비슷한 성향을 가진 식품군에 대조하여 판단해야 하는 어려움이 있었다. 따라서 기존의 기준에 대하여 검토 또는 변경을 거쳐 식물성대체육에 대한 관리기준이 설정한다면 유사한 식품군의 건전성 및 적합성을 유지하는 것에 도움이 될 것으로 판단된다.
