This test method is an official culture-based and immunological method for the detection and confirmation of Escherichia coli O157:H7 in food samples. It combines selective enrichment, immunomagnetic separation, and immunoassay detection to provide accurate and sensitive identification of this pathogenic strain.
This test method is an official gravimetric procedure for determining calcium carbonate (CaCO₃) content in samples such as minerals, supplements, and food additives. The method involves acid digestion of the sample and measurement of the resulting carbon dioxide to quantify the effective calcium carbonate equivalence.
This test method is a cross-method calculation involving total digestible nutrients, net energy for lactation, net energy for maintenance, net energy for gain, digestible energy, and metabolizable energy analyses.
This test method is a cross-method calculation involving digestible energy and metabolizable energy analyses.
This test method is a standardized microbiological procedure for the detection and enumeration of Enterobacteriaceae in food and environmental samples. This method utilizes selective culture media and incubation conditions to isolate and quantify members of this important bacterial family.
This test method is a standardized analytical procedure for the quantitative determination of ethanol and methanol concentrations in fuel ethanol. The method typically uses gas chromatography (GC) to separate and measure these alcohols with high accuracy and precision.
This test method is a semi-quantitative headspace analysis to determine the concentration of ethanol found in oil samples using GC (gas chromatography) technology.
This test method is a standardized procedure for the detection and quantification of external light filth—such as insect fragments, hair, fibers, and other extraneous materials—in grains and seeds. The method uses a sieve analysis technique.
This test method uses GC (gas chromatography) technology to characterize and quantify volatile polar compounds found within commercial oil processes with specific focus on ethanol esterified fatty acids. This test method quantifies ethyl palmitate, ethyl stearate, ethyl oleate, ethyl linoleate, as well as total fatty acid ethyl esters.
The FCC (Food Chemicals Codex) method for Acidity as Acetic Acid in Ethanol is a titrimetric procedure used to quantify the free acidity in ethanol by expressing it as an equivalent amount of acetic acid. This test helps assess the purity and quality of ethanol, especially in food, pharmaceutical, and beverage applications.
