This test method is a rapid and reliable procedure for detecting Salmonella spp. in food, feed, and environmental samples. This method is valued for its speed, sensitivity, and specificity in detecting Salmonella in complex samples.
This test method contains standardized guidelines for conducting sensory evaluation panels to assess and measure human responses to products, including food, beverages, and other materials.
This test method is a procedure that uses headspace gas chromatography (GC) to detect and quantify residual hexane in vegetable oils that have been processed using solvent extraction.
This test method is a standardized method outlining procedures for sieve analysis to determine the particle size distribution of various materials. This test method ensures a consistent and reproducible approach to evaluating particle size.
This test method is a calculation to determine organic nitrogen value from the crude protein/nitrogen and ammonium nitrogen values of animal feed and feed ingredients.
This test method is a calculation to determine organic nitrogen value from the crude protein/nitrogen and ammonium nitrogen values of manure samples.
This test method is a standard method used to measure organic nitrogen concentrations in water and wastewater samples. Organic nitrogen refers to nitrogen bound within organic compounds, distinct from inorganic nitrogen forms like ammonia or nitrate.
This test method follows FDA Table 2, which is a procedure used to identify and quantify organic impurities in fermentation products. This test involves a liquid extraction of feed samples prior to analysis.
This test method is a traditional and widely used technique to determine the proof (alcohol strength) of ethanol-based liquids by measuring their specific gravity (SG) or density.
