海能仪器:电位滴定法检测小麦、糙米的脂肪酸含量

粮食脂肪酸值是检验粮食中游离脂肪酸含量多少的量值。其检验结果以中和 100g 粮食试样中游离脂肪酸所需氢氧化钾的毫克数来表示。脂肪酸值的变化反映了稻谷常用的品质劣变程度。在国标的谷物储藏判定规则中,作为稻谷、小麦的宜存指标。 本文采用并改进了国标中的第二法,实验证明 T960 电位滴定仪测定结果重复性良好, 满足国标中第二法中对于电位滴定仪的要求。

气相色谱法测定粮食中氯化苦残留量

本文采用无水乙醇提取粮食中氯化苦对分析人员健康和环境危害小,操作简单,干扰因素少,所用器材、试剂简单,灵敏度高,重复性好。可用于粮食中氯化苦残留量的检验。

直接提取进样石墨炉原子吸收法测定大米中的镉含量

镉长期在人体蓄积,会导致肾脏损伤,危害人体健康。镉是粮食卫生指标的必检项目。国家标准中测定食品中镉含量的方法有石墨炉原子吸收法、火焰原子吸收光谱法、比色法和原子荧光法。传统方法测定食品中的镉主要用湿法、干法、微波消解等方式处理样品,耗时费力,且需要用到酸,过氧化氢等试剂,污染环境并造成检测人员的健康损害。
