摘要
采用四丁基氢氧化铵为离子对试剂,以C18色谱柱为固定相,建立检测酱油中乙二胺四乙酸铁钠(NaFeEDTA)高效液相色谱法。结果表明:NaFeEDTA的添加量为2.00g/L时,在10种不同品牌酱油中的回收率为94.1%~101.5%,平均回收率为97.7%,测量结果与国标方法没有显著差异(P〉0.05)。本方法具有通用性好的优点,可用于铁强化酱油中NaFeEDTA的检测。
An HPLC method was developed for the determination of sodium iron ethylenediaminetetraacetate (NaFeEDTA) in soy sauce on a C8 column with tetrabutylammonium hydroxide as ion-pair reagent in the mobile phase. In 10 different kinds of soy sauce, at the spiked level of 2.00 g/L, the recovery rates of NaFeEDTA were in the range of 94.1%--101.5%, with an average of 97.7%. The measurement results had no significant difference with those obtained by the national standard method (P 〉 0.05). This method with good versatility can be used for the determination of NaFeEDTA in soy sauce.
