Detection principle:

The TKJ-I portable fatty acid value rapid detection system adopts the spectral energy comparison method. The free fatty acid components in grains are extracted by organic reagents and react with specific detection reagents to generate colored compounds. The reacted solution conforms to Lambert Beer's law. The fatty acid value detector is used to measure its absorbance at a specific wavelength and compare it with the built-in specific spectral energy value to determine whether the sample exceeds the standard. The instrument is pre-set or selectively set according to the numerical requirements of grain storage indicators, which is convenient for use in procurement sites or laboratory rapid detection.
