【摘要】 [目的]建立海产品中亚铁氰化钾分析技术,提高食品检验技术水平。[方法]利用蛋白加热变性和低温凝聚的原理对样品进行预处理,分离样品中的蛋白质、脂肪。采用低温、静止、盐重解析技术,降低亚铁氰化铁在溶液中的溶解度,通过改变分析溶液消去杂色光的干扰,增加分析方法的縻尔吸光系数。[结果]经实验验证方法精密度0.028,准确度97.8%,最低检出限为0.25μg/g,达到分析实验的要求。[结论]本方法快速、准确可靠,适合海产品中亚铁氰化钾含量测定。更多还原

【Abstract】 [Objective]To set up the analytic technique of potassium ferrooyanide in marine product.[Methods]The samples were pretreated utilizing the denaturalization of protein when heated, and the agglomerate of it in low temperature. Then the content of the material determined was detected adopting the salt resolve to change the density of the solution.[Results]The precision (S) of the method was 0.028,the veracity was 97.8%,and the lowest detection limit was 0.25μg/g.[Conclusion]This method is simple. The result is accurate and reliable.更多还原
