Abstract

The Chinese red-headed centipede Scolopendra subspinipes mutilans, a member of the arthropod class Chilopoda, is a traditional medicine used for the treatment of several allergic diseases, such as atopy. S. subspinipes mutilans samples were collected from different regions of South Korea: Sancheong, Gyeongnam; Yeonggwang, Jeonnam and Jeju-do. The nutritional values of the centipedes were analyzed to extend the species' applications. The crude protein and fat contents of all samples were high and ranged from 54.9-55.8% and from 26.8-30.6%, respectively. Essential amino acids were present; lysine was the most common and accounted for 3.4-3.6% of the essential amino acids. Glutamic acid, which assists in improving concentration, memory and other cognitive abilities, was the most common non-essential amino acid at 6.8-7.1%. It had a similar content percentage in all three regions' samples. Additionally, unsaturated fatty acids were present, and oleic acid, which prevents cancer and cardiac disease, was the most common at 41.3-48.6% of each sample. Mercury, a hazardous substance, was detected at a range of 0.08-0.11 mg/kg in all samples; the amount was lower than the standard food allowance. Additionally, no pathogenic microorganisms, such as Escherichia coli and Salmonella spp., were detected. There were no significant differences between the nutritional factors of the S. subspinipes mutilans samples from the three regions. Based on the nutritional analysis, Chinese red-headed centipedes have the potential to be food and medicinal ingredients due to their proteins, essential amino acids, unsaturated fatty acids and nutritive capacities.

국내산 왕지네(Scolopendra subspinipes mutilans)의 식 약용으로써의 이용 가능성을 알아보고자 경남 산청, 전남 영광, 제주도 지역 왕지네의 영양성분 및 유해물질을 비교분석한 결과, 일반성분 중 조단백질은 3개 지역에서 54.9-55.8%로 전체적으로 매우 높은 함량을 나타냈고 조지방은 26.8-30.6%였다. 필수아미노산에서는 라이신이 3.4-3.6%로 가장 많았다. 집중력과 기억력 증진 및 인지능력 개선에 도움이 되는 glutamic acid는 비필수아미노산 중 가장 많은 함량인 6.8-7.1%로 지역 간에 비슷하였다. 불포화지방산에서는 심장질환 및 암 예방에 효과가 있는 oleic acid가 지역 간에 41.3-46.8%로 가장 높은 함량을 보였다. 유해물질 분석 결과, 3개 지역에서 중금속인 수은이 0.08-0.11 mg/kg 검출되었으나, 일반식품 허용 기준치 이하로 확인되었다. E. coli와 Salmonella spp.와 같은 병원성 미생물은 검출되지 않았다. 지역별로 국내산 왕지네의 영양성분 및 유해물질 비교분석 결과, 지역 간에 뚜렷한 차이는 없었다. 왕지네는 단백질, 필수아미노산, 불포화지방산 및 체내에서 합성하지 못하는 많은 영양소들을 함유하고 있기 때문에 식 약용으로 활용될 가치를 충분히 가지고 있다고 판단되었다.
