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 gravimetric method used to determine crude fiber content in oilseed meals, animal feeds, and related agricultural products. Crude fiber consists of the indigestible portion of plant material, primarily cellulose and lignin, remaining after digestion with dilute acid and alkali.
This test method is a gas chromatography (GC-FID)-based procedure for the quantitative determination of cis-, trans-, saturated, monounsaturated, and polyunsaturated fatty acids in vegetable oils and non-ruminant animal fats. This method enables detailed fatty acid profiling critical for nutritional labeling, product formulation, and quality control.
This test method is a gravimetric method used to determine the crude fiber content in oilseed byproducts, such as soybean meal, cottonseed meal, canola meal, and other plant-based feed materials. Crude fiber represents the indigestible portion of the sample that remains after chemical digestion, primarily composed of cellulose and lignin, but excluding more soluble fiber… Continue reading Crude Fiber [Oilseed Byproducts]
This test method is a combustion method for determining crude protein in soybean meal, using high‑temperature combustion in pure oxygen to release nitrogen that is then measured and converted to protein. It is also the officially designated crude‑protein method used for NOPA referee testing.
This test method is a classical gravimetric method used to determine crude fat content in animal feeds through solvent extraction. It is widely applied in feed analysis to quantify the total fat (lipid) content, including triglycerides, phospholipids, and other ether-soluble materials.
This test method is a classical gravimetric method used to determine crude fat content in animal feeds through solvent extraction. It is widely applied in feed analysis to quantify the total fat (lipid) content, including triglycerides, phospholipids, and other hexane-soluble materials.
This test method is a classical gravimetric method used to determine crude fat content in animal feeds through solvent extraction. It is widely applied in feed analysis to quantify the total fat (lipid) content, including triglycerides, phospholipids, and other hexane-soluble materials. High moisture samples are mixed with celite, or diatomaceous earth, prior to analysis to… Continue reading Crude Fat [Hexane w/ celite]
This test method determines oil content in oilseed meals and cakes by measuring the petroleum‑ether–soluble fraction under defined extraction conditions. It is also the designated official oil analysis method used in NOPA referee testing.
