中文摘要: 为提高进出口对虾风险监控水平,利用反相高效液相色谱法测定不同形态中国对虾贮藏过程中产生生物胺的 变化,结合感官检验、pH 和菌落总数检测结果,分析对虾腐败进程及其原因。结果表明,在 0 ℃和 4 ℃下贮藏,腐胺和尸 胺变化最显著,贮藏第 10 天质量分数分别为(206.48±14.19) mg/kg,(162.45±18.13) mg/kg 和(397.48±14.19) mg/kg, (201.95±15.84)mg/kg;25 ℃下贮藏产生的主要生物胺是酪胺,贮藏 10 天质量分数达(675.66±20.25)mg/kg,其次是腐胺 和尸胺。确定不同形态的对虾在 0、4、25 ℃下贮藏,整虾的可接受期为 5、4、1 d,虾仁可接受期为 7、5、1 d,细菌是造成虾 体内生物胺累积的主要原因。
Abstract:In order to improve the level of imports and exports of shrimp risk monitoring, measuring different forms of Chinese shrimp produced changes in biogenic amines during storage, combined with sensory testing using reverse-phase high performance liquid chromatography, pH and the total number of colonies of the test results, the analysis process and the reasons for corruption shrimp . The results show that at 0 ℃ and 4 ℃ storage, putrescine and cadaverine was most remarkable, storage first 10 days quality scores were (206.48 ±14.19) mg/kg,(162.45±18.13) mg/kg and (397.48±14.19) mg/kg, (201.95±15.84) mg/kg; mainly biogenic amines produced under 25 ℃ storage is tyramine, storage 10 days the mass fraction of (675.66±20.25) mg/kg, followed by putrescine and cadaverine. Determine the different forms of shrimp at 0,4,25 ℃ storage, whole shrimp acceptable period of 5,4,1 d, shrimp acceptable period of 7,5,1 d, bacteria are the main cause of shrimp in vivo accumulation of biogenic amines .
