GB/T 22427.6-2008 《Starch - Determination of whiteness》 Related products

GB/T 2 2427.6 - 2008 "Determination of starch whiteness" standard stipulates the method of measuring starch whiteness using a light reflection whiteness meter, which is suitable for drying powdered starch and modified starch. The whiteness of the sample is determined by comparing the blue light reflectance of the sample with the standard whiteboard. The standard requires the use of accurate whiteness meters and standard whiteboards for determination, and parallel experiments are carried out to ensure the Reliability of the results. The measured whiteness value should be based on the whiteness meter reading, and Repeatability tests should be carried out to verify the accuracy. The experimental report should record the method, results and sexual repeability experimental data in detail.
