Determining the Physical Characteristics of Milled Rice
       
  Which conditions damage rice grains and how does this affect the quality of milled rice?  
  Determine the conditions that cause damaged rice grains and perform a procedure for measuring their percentagee.  
     
How are rice grains damaged?
  

Before milling, paddy rice can deteriorate through natural biochemical changes in the grain which can create off-odors and changes in physical appearance. The result is damaged grains that are fully or partially darkened. Other causes of damage include insect , mold, water, or heat damage.
