Description

一种矿物油检测试剂及其应用
技术领域
本发明涉及一种矿物油检测试剂及其应用。
背景技术
矿物油来源于石油分馏的产物，属于较高级的直链烷烃，而食用油脂系高级脂肪酸的甘油酯，尽管外观有某些相似，但其化学性质有很大的差别。
发明内容
本发明的目的就是针对上述现有技术中的缺陷，提供了能够检测食品油中矿物油的检测试剂。
为了实现上述目的，本发明提供的技术方案为：一种矿物油检测试剂，包括有按重量份计的以下组分：氢氧化钠溶液20-30份，无水乙醇15-24份，丙酮8-14份，废白土6-9份，二硫化碳2-6份。
本发明的第二个目的是提供了上述一种矿物油检测试剂在检测食用油中矿物油的应用。
进一步的，上述的应用，是将上述的矿物油检测试剂，加入至食用油样品中，并于80-100℃热水中加热10分钟后，再加入蒸馏水，观察混浊程度即可。
本发明的有益效果为：本发明提供的矿物油检测试剂，检出率高出同类产品25-40%，同时，操作简单，检测效果直观，检测速度快。
具体实施方式
实施例1：
一种矿物油检测试剂，包括有按重量份计的以下组分：氢氧化钠溶液20-30份，无水乙醇15-24份，丙酮8-14份，废白土6-9份，二硫化碳2-6份。
上述一种矿物油检测试剂在检测食用油中矿物油时，是将上述的矿物油检测试剂，加入至食用油样品中，并于80-100℃热水中加热10分钟后，再加入蒸馏水，观察混浊程度即可。
最后应说明的是：以上所述仅为本发明的优选实施例而已，并不用于限制本发明，尽管参照前述实施例对本发明进行了详细的说明，对于本领域的技术人员来说，其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分技术特征进行等同替换。凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
