Determining the Physical Characteristics of Paddy Rice
       
  How do immature grains reduce the quality of paddy rice?  
  Calculate the impact of immature grains on paddy rice quality and perform a procedure for determining the percentage of immature grains in a paddy rice sample.  
     
The effect of immature grains on quality
 

Immature grains are very slender, have a chalky appearance, and do not survive the milling process very well. If paddy rice contains a high percentage of immature grains, milling will create excessive bran, broken grains, and brewer's rice.

 
   
Broken rice - Paddy rice that contains a high percentage of immature grains will break during milling.
