This test method is a rapid and sensitive technique for detecting melamine—a contaminant associated with serious pet food and animal feed safety incidents. The testing was prompted by widespread animal illness and fatalities caused by melamine-cyanuric acid crystal formation in the kidneys of pets consuming adulterated food.
This test method determines the color of oils and other transparent liquids by comparing samples to calibrated Lovibond® or Gardner liquid standards, providing a standardized visual evaluation of red/yellow (RYBN) tint and overall Gardner color to ensure consistent color grading across batches.
This test method is a validated rapid detection method for the qualitative identification of Listeria species, including but not limited to Listeria monocytogenes, in food and environmental samples. It is approved through the AOAC Performance Tested Methods (PTM) program, ensuring it meets rigorous criteria for sensitivity, specificity, and reliability when compared to traditional reference methods.
This test method is a rapid molecular detection method validated for the qualitative detection of Listeria monocytogenes in food and environmental samples. This method was evaluated and approved under the AOAC Performance Tested Methods program, confirming its reliability and equivalence to reference culture-based methods.
This test method is a presumptive quantification of leuconostoc spp. in fermentation samples found within the ethanol production process.
This test method is a calculated value used to assess the scaling or corrosive tendency of water, particularly in water treatment, cooling systems, boilers, and municipal water supplies. It indicates whether water will precipitate, dissolve, or be in equilibrium with calcium carbonate (CaCO₃).
This test method is a standardized titration procedure for measuring the Iodine Value (IV), which quantifies the degree of unsaturation (number of double bonds) in fats and oils. The iodine value represents the grams of iodine absorbed by 100 grams of sample.
This test method is a standard titrimetric procedure used to measure total hardness and calcium hardness in water, both expressed as mg/L of calcium carbonate (CaCO₃). Hardness is primarily due to the presence of calcium (Ca²⁺) ions.
This test method determines the concentration of glycerin with a calculation involving the specific gravity and relative density of the glycerin sample.
