Abstract
The autoxidation of cholesterol and lipid was investigated in mackerel during its salting for 50 days. Furthermore, the effects of antioxidants such as ascorbic acid and BHA on their autoxidation were studied. The cholesterol of mackerel during salting was continuously decreased. Its content was quantified by 23.3mg/100g in salted control sample after 50 days and that is only about 33% of total cholesterol content in fresh mackerel. The addition of BHA in mackerel during salting inhibited cholesterol oxidation more effectively than ascorbic acid.7-Ketocholesterol, unique cholesterol oxidation products was detected in this experiment and malonaldehyde, one of lipid oxidation products, contineuosly increased in control sample all the salting days by the almost same pattern but in the additive samples of ascorbic acid or BHA by different patterns, respectively. BHA was more effective antioxidant against cholesterol and lipid autoxidation than ascorbic acid.
수산식품 중 비교적 다량의 다불포화지방산과 함께 콜레스테롤을 함유하고 있는 고등어를 50일간 염장하면서 콜레스테롤 및 지질의 산화와 이들 산화에 미치는 아스코르빈산 및 BHA의 영향에 대해 조사하였다. 고등어의 염장 중 콜레스테롤은 계속 산화분해되어 대조군의 경우 50일간 염장한 후에는 23.3mg/kg으로 생시료 함량의 33%에 불과했으나 아스코르빈산 첨가군은 염장
