The combustion method for neutral detergent insoluble protein (NDIP) is used to measure the amount of indigestible protein bound within the fiber portion of animal feed, particularly relevant for assessing heat-damaged or low-quality proteins. In this method, the feed sample is treated with an acid detergent solution to isolate the neutral detergent fiber (NDF), which… Continue reading Neutral Detergent Insoluble Protein [Kjeldahl]
This test method is a procedure for calculating the Nitrogen-Free Extract (NFE) in food and feed samples. NFE represents the portion of carbohydrates that are not accounted for by fiber, moisture, ash, or protein, essentially reflecting the readily digestible carbohydrate content.
This test method is a procedure for the determination of Non-Protein Nitrogen (NPN) in various samples, primarily in dairy products and animal feeds. NPN includes nitrogen compounds not incorporated into proteins, such as free amino acids, urea, and ammonia.
This test method is an official method established by the American Oil Chemists’ Society (AOCS) for determining the moisture and volatile matter content in oilseed byproducts, such as meals, flours, and cakes. It uses a forced-draft oven to ensure uniform drying and accurate results. A known weight of sample is dried in an oven at… Continue reading Moisture – 130°C [Oilseed Byproduct]
This test method is an official method from the American Oil Chemists’ Society (AOCS) used to determine the moisture and volatile matter content in whole soybeans. This gravimetric method is based on oven drying and is essential for assessing the quality, storage stability, and processing characteristics of soybeans. A known weight of sample is dried… Continue reading Moisture – 130°C [Oilseed]
This test method is a classic, officially recognized method for determining moisture content in animal feed using an air oven drying technique. This gravimetric method is widely used in feed laboratories for routine moisture analysis, helping ensure accurate nutrient formulation and product stability. A known weight of sample is dried in an oven at a… Continue reading Moisture – 135°C
This test method is a standardized method for determining moisture content in forage samples, important for accurate dry matter determination.
This test method is a procedure for determining moisture content in various food products using a vacuum oven drying technique. This method is particularly useful for samples sensitive to heat or prone to oxidation during drying.
This test method is a widely used immunoaffinity column (IAC) based assay designed for the detection and quantification of total aflatoxins (B1, B2, G1, and G2) in various food and feed samples. It offers a rapid, sensitive, and user-friendly approach for screening aflatoxin contamination.
This test method is a standard method for the determination of Deoxynivalenol (DON), a mycotoxin, in cereals and cereal-based products using ultra-performance liquid chromatography coupled with tandem mass spectrometry (UPLC-MS/MS) with a single chromatographic column.
