摘要:傳統(tǒng)瘦肉精主要指鹽酸克倫特羅,已被禁止作為飼料添加劑使用,以往國家執(zhí)法人員也多檢測鹽酸克倫特羅。近年來,β-腎上腺素興奮劑中的另一些藥物如苯乙醇胺A、萊克多巴胺、沙丁胺醇等新型瘦肉精添加事件也屢見報道,因此迫切需要研究更、更快速、應(yīng)用更廣泛的檢測瘦肉精的方法。本文重點介紹了目前國內(nèi)外用于檢測新型瘦肉精殘留的常用方法,如色譜法、紅外光譜分析法、毛細管區(qū)帶電泳法(CE)、免疫分析技術(shù)(IA)和生物傳感器技術(shù)(BS)等檢測方法的優(yōu)缺點,為相關(guān)部門提供參考。

AbstractTraditional Clenbuterol which was used as one of the feed additives has been banned. The national law enforcement officers mainly detected Clenbuterol in the past. Recent years, some other drugs of the β-agonists such as phenylethanolamine A, ractopamine, salbutamol have also been used as new clenbuterols Therefore, a more efficient, faster, more widely used method for  detection new clenbuterols is an urgent need. This article focuses on the common methods such as chromatography, capillary zone electrophoresis (CE), immunoassay (IA) and biosensor technology (BS),which are currently used to detect the new types of clenbuterol residues at home and abroad. The article also analyzes the advantages and disadvantages of the detection methods and provides a reference for the relevant departments.

 “瘦肉精通常指β-腎上腺素興奮劑,簡稱β-興奮劑或β-激動劑,傳統(tǒng)瘦肉精主要指鹽酸克倫特羅,被廣泛用于治療動物和人的阻塞性支氣管哮喘[1,2],新型瘦肉精指苯乙醇胺A、萊克多巴胺、沙丁胺醇、硫酸特布他林、西巴特羅、鹽酸多巴胺等藥物,在飼料中添加這些藥物能使禽畜肌肉比例提高,增大禽畜的瘦肉率,因此β-興奮劑一度被用于畜牧生產(chǎn)[3,4]。然而β-興奮劑在內(nèi)臟中的蓄集較嚴重,通過食物鏈進入人體后,會產(chǎn)生毒副作用,導(dǎo)致頭暈、心悸等中毒癥狀,嚴重危害身體健康[5,6]。以往國家執(zhí)法人員檢測瘦肉精殘留多指鹽酸克倫特羅,近年來新型瘦肉精苯乙醇胺A、萊克多巴胺等也被列入檢測范圍。因此,研發(fā)新型瘦肉精簡單、快速、靈敏的檢測方法是大勢所趨,也迫在眉睫。   

本文對目前β-腎上腺素興奮劑主要檢測方法進行介紹,通過分析、對比展示了各方法的優(yōu)缺點,為相關(guān)部門建立新型瘦肉精的檢測標(biāo)準(zhǔn)提供參考依據(jù)。

色譜法

目前,實驗室檢測新型瘦肉精殘留的方法主要有色譜技術(shù)和免疫分析技術(shù)等,色譜技術(shù)為檢測瘦肉精的經(jīng)典技術(shù),主要有薄層層析色譜法、高壓液相色譜(HPLC)、高壓液相色譜/二極管陳列、高壓液相色譜/熒光、液相色譜/質(zhì)譜聯(lián)用(HPLC/MS)、氣相色譜-質(zhì)譜法(GC/MS)、氣相色譜/傅立葉紅外聯(lián)用等,下面介紹幾種主要的殘留檢測方法。
