浅析一种快速法测定鲜胶乳挥发脂肪酸值

Analysis of a Rapid Method for Determination of Volatile Fatty Acid Value of Fresh Latex

采用一种快速法测定鲜胶乳挥发脂肪酸值(VFANo.),通过与标准法测定结果对比,结果发现快速测定法测定鲜胶乳挥发脂肪酸值不需关联总固体含量(TSC)、干胶含量(DRC),每样品测定平均耗时30 min,而标准法测定需关联TSC、DRC,每样品测定耗时为6 h,说明快速法检测效率提高了12倍,解决了加工厂鲜胶乳质量验收"先测后放"技术难题,对鲜胶乳进厂质量验收及其后续浓缩胶乳产品质量控制具有十分重要的意义。

A rapid method was used to determine the volatile fatty acid value(vfano.)of fresh latex.Compared with the results of standard method,it was found that the volatile fatty acid value of fresh latex determined by rapid method do not need to correlate the total solid content(TSC)and dry rubber content(DRC),and the average determination time of each sample is 30 mins,while the standard method need to correlate TSC and DRC,and the determination time of each sample is 6 h.It shows that the detection efficiency of the rapid method is increased by 12 times,which solves the technical problem of"testing before releasing"in the quality acceptance of fresh latex in the processing plant.It is of great significance to the quality acceptance of fresh latex and the quality control of subsequent concentrated latex products.
