Standard amylose procedure and modified amylose procedure were compared in the paper.There are following advantages in modified arnylose procedure.not only milled or brown rice powder but also milled or brown rice grains can be analyzed and the testing standard differences are much smaller.The order of amylose content (AC)of different type samples in a variety was:milled rice grain>milled rice powder and brown rice grain>brown rice powder.KOH should be used while analyzing milled rice grain or powder,and NaOH should be used while analyzing brown rice grain or powder should chose.100 mg sampling weight is better,but less than 100 mg can also be used when comparing varietal amylose content.
