原料乳中硼酸、硼砂快速检测方法研究

Study on A New Method for Rapid Detection of Boricacid and Borax

【目的】建立一种快速检测牛奶中掺硼酸、硼砂的方法。【方法】将配制的姜黄素试剂加载到定性滤纸上,制作成检测试纸,对原料奶中掺入不同浓度的硼酸、硼砂进行检测,并对该法所需试剂的用量和试剂保存期等影响因素进行了系统的考察和优化。【结果】在最佳方法和操作条件下,可检出硼酸和硼砂的最低下限分别为25和10μg/mL乳。【结论】筛选出的检测方法具有灵敏,操作简便,掺假现象容易判断和把握,检测费用低廉等特点,便于在实际生产中推广应用。

[Objective]In this paper the methods for rapid detection of boricacid and borax in fresh milk was studied through the test. [Method] The curcumin reagent were prepared, and transfered to the qualitative filter paper, then the prepared turmeric paper was used to detect the boricacid and borax in fresh milk , and systematic observation and optimization were conducted on the affecting factors needed for the method including the dosage of test reagent and its storage period. [ Result] Under the optimum operation conditions, the lowest limit of boricacid and borax detected was25 μg/mL milk , 10 μg/mL milk respectively. [ Conclusion] The method was sensitive, simple,and it is very cheap and convenient to inspect, also it is simply and easily popularized and applied in production.
