摘要
采用60Co-γ辐照分别对含有3-甲基-喹噁啉-2-羧酸(MQCA)、氯霉素和苏丹红Ⅰ~Ⅳ的动物源食品进行处理,设置辐照剂量为0~10 k Gy,考察了其在不同辐照剂量下的降解情况。结果表明,当辐照剂量为9 k Gy时,鸡肉中MQCA和蛋液中苏丹红Ⅰ~Ⅳ的降解效果非常显著,降解率分别为99.0%和83.5%~95.7%;而蛋粉中的苏丹红Ⅰ~Ⅳ的降解效果相对较差,降解率仅为9.3%~22.3%;鳗鱼冻干粉中氯霉素的降解效果比较显著,降解率为75.3%。随着辐照剂量的增大,其降解率逐渐增大。研究表明辐照处理可对食品中某些化合物产生有效降解。
The effects of radiation dose on the degradation rate of 3- methyl- quinoxaline- 2- carboxylic acid（ MQCA）,chloramphenicol and SudanⅠ-Ⅳ were studied.60Co- γ ray at different radiation doses（ 0 -10 k Gy） was applied for the foods of animal origin contaminated with residues.The results showed that60Co- γ irradiation could significantly degrade MQCA in chicken and Sudan Ⅰ- Ⅳ in egg liquid.When the radiation dose was 9 k Gy,the degradation rates were up to 99.0% and 83.5% - 95.7%,respectively.The degrading effect of sudan Ⅰ- Ⅳ in egg powder were not obvious,the degradation rates were only 9.3% - 22.3%. And the degradation of chloramphenicol was 75.3%.To all of them,the degradation rate went up with the increase of radiation dose.This study showed that irradiation treatment was effective to degrade some compounds in foods.
