摘要
Abstract
According to the principle that borax is converted to boric acid under acid condition,and boric acid has color reaction with curcumin,the image of the color reaction between borax and color liquid was collected by self-designed image acquisition sensors,the rapid method to screen borax in wheat flour based on computer and colorimetry was set up by LabVIEW design image processing software.The chro-mogenic condition of the chromogenic system and the operation function of the software were optimized. The results showed that the brightness I value of the color system was linear with boric acid in the range 0~4 mg/L.The borax content and I value curve was determined.The relation curve formula was planted into data analysis system,after collecting the images,the actual level of borax was automatically acquired by the software.The method used for the actual sample analysis,and the recovery of standard addition was 96.6%~96.6%,RSD was 1.18%~3.14%.关键词
