본문내용

식품에는 탄수화물, 단백질, 지방, 무기질 등과 같은 생명체의 유지에 매우 중요한 영향을 미치는 많은 영양소가 포함되어 있다(1). 그 중 단백질은 체조직 구성, 체내 에너지 공급 및 대사 조절의 기능을 수행하는 필수적인 영양소이다(2). 단백질과 지방질이 함유된 식품들은 미생물에 의하여 분해가 되는데(3), 분해과정의 생성물이 인체에 유익한 물질이면 발효라 하고, 유해한 물질을 생성하면 부패라고 한다(4). 부패의 판정 방법에는 관능평가, 미생물 측정, VBN (Volatile basic nitrogen) 함량 측정 등의 방법이 있으며(5), VBN 함량을 측정하는 방법 중 Conway 미량확산법은 육상 식품의 암모니아, 수산 식품의 암모니아와 trimethylamine을 측정하는 방법이다(6).
꽁치는 양질의 단백질과 지질이 다량 함유되어 있고, 암이나 심장 혈관계 질환같은 성인병을 예방하는 DHA와 EPA가 많이 함유되어있으며(7) 비타민과 철분이 많아 시력 향상과 악성 빈혈에 도움을 주는 주둥이가 뾰족하고 긴 등푸른 생선이다(8).
