The TCVN 8372-2010 standard specifies methods for measuring transparency, whiteness and whiteness ratio of white rice to evaluate the appearance mass and processing performance of white rice. The standard ensures the accuracy and conformity of measurement results by specifying test conditions for transparency and whiteness, sample preparation, instrument calibrating and data processing methods. Transparency tests reflect the light transmission performance of rice grains, while whiteness and whiteness ratios measure the color and uniformity of rice grains. The standard provides a scientific basis for mass grading and market circulation of white rice. It is widely used in rice production, processing and mass testing, helping to improve the commercial value and consumer satisfaction of white rice.
