Effect of thymol on freshness and shelf life of turbot （ Scophthalmus maximus） during cold storage
摘要
Abstract
Freshness changes and shelf life of turbot（Scophthalmus maximus） were investigated by testing the indexes of sensory evaluation,total volatile base nitrogen （TVBN）,trimethylamine （TMA）,total aerobic counts, H2S-producing bacteria and inhibition index（Ⅰ.Ⅰ） during storage at 3℃,compared control group（C） that dipped into distilled water with the fresh group（F） dipped into lg/kg thymol solution,then inquired into the fresh effects of thymol to turbot. The results showed that quality of turbot still was in high condition on 259 and 309h, respectively,and quality achieved unacceptable on 403 and 572h at their end of shelf life,which prolonged 169h compared F with C after dipping into thymol. At the end of good quality life,the values of TVBN were 13.60,10.70mg/100g,and 32.69,35.87mg/100g at the end of shelf life,respectively. The values of TMA reached 1.26,1.05mg/100g at the end of good quality,and 6.57,7.57mg/100g at the end of shelf life,respectively. The counts of total aerobic counts were 7.65,6.591g（CFU/g） at the end of good quality and 8.27,8.561g（CFU/g） at the end of shelf life, respectively. The counts of H~S-producing bacteria were 7.15,5.411g （CFU/g） at the end of good quality life, 7.37,6.131g （CFU/g） at the end of shelf life, respectively. Moreover,at the beginning of storage the inhibition indexs of total aerobic counts and H2S-producing bacteria were 57.02% and 100% ,and they were 16.34% ,45.73% at the end of good quality life of control,4.72% and 19.72% at the end of shelf life of control, respectively.关键词
