Determining the Physical Characteristics of Milled Rice
       
  What causes red and red-streaked grains and how can this affect the quality of milled rice?  
  Perform the procedure for measuring the percentage of red and red-streaked rice grains.  
     
What are red and red-streaked grains in milled rice?
 

Red and red-streaked grains occur when part of the bran layer is still clinging to the surface of the grain after milling. Rice consumers almost universally desire well-milled rice because of its better appearance. Therefore, the presence of red and red-streaked grains suggests a lower degree of milling and subsequently, a less desirable appearance.
