This test method is an in vitro assay that uses pancreatin enzymes to simulate the digestive process and assess the digestibility of feedstuffs or food ingredients. Pancreatin, a mixture of digestive enzymes including proteases, amylases, and lipases, mimics the enzymatic activity in the small intestine.
This test method is a standardized procedure to assess the in vitro digestibility of protein using the enzyme pepsin, which simulates gastric digestion. This method estimates how much protein in a sample can be broken down under stomach-like conditions.
This test method is a widely used standard procedure for measuring the peroxide value, which quantifies the amount of peroxides and hydroperoxides—primary oxidation products—in oils and fats. Oil is extracted from the feed sample prior to a titration to determine the free fatty acid content. This value is an important indicator of the early stages… Continue reading Peroxide Value [Feed]
This test method is a colorimetric enzymatic method designed for the quantitative analysis of phytic acid and total phosphorus in food and feed samples.
This test method is an enzymatic-colorimetric method used to determine Primary Amino Nitrogen (PAN) in food, beverage, fermentation, and agricultural samples.
This test method utilizes a pre-column ACQ derivatization combined with UPLC to provide a sensitive and specific measure of reactive lysine in heat-processed feed ingredients. This method supports accurate predictions of lysine digestibility and bioavailability in animal nutrition.
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 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 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 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
