Standardization of Moisture, Protein, Oil and Starch Measurements in Grain
Gloria Diane Lee
Grain is an essential source of the world's human and animal food supply. The production value of major grains in the United States is approximately $3.3 billion (U.S.D.) of the $10.1 trillion of the U.S. gross domestic products. Inaccurate grain measurements (moisture, protein, starch and oil) can have a large economic impact on the grain market.This paper covers the following topics: (1) an overview of the impact and importance of grain measurements; (2) information on the grain measurement system before the collaborative efforts among the National Institute of Standards and Technology (NIST), the United States Department of Agriculture (USDA), Grain Inspection Packers and Stockyards Administration (GIPSA), State Weights and Measures (W&M) agencies, the National Conference on Weights and Measures (NCWM), and device manufacturers, and the coordination among these groups; 3) improvments in standardizain commercial inspections of grain measurements; and (4) ISO/IEC 17025 compliance issues.
