This test method is a standardized procedure to determine the saponification value of fats and oils, which measures the amount of potassium hydroxide (KOH) in milligrams required to saponify one gram of the sample.
This test method is a standardized procedure to determine the saponification value of fats and oils, which measures the amount of potassium hydroxide (KOH) in milligrams required to saponify one gram of the sample.
This test method is a standardized procedure used to determine the soap content in fats and oils, particularly refined vegetable oils. This method is crucial for processors monitoring the efficiency of oil refining and verifying product compliance with industry standards.
This test method determines potassium hydroxide (KOH) protein solubility, and is an effective, rapid screening tool to detect overprocessing in oilseed byproducts.
This test method is an official method used to determine the specific gravity and density of alcoholic beverages. The method involves measuring the mass and volume of a known quantity of sample at a standardized temperature. Specific gravity is calculated as the ratio of the sample’s density to the density of water at the same… Continue reading Specific Gravity / Density
This test method is a standardized method that determines the total sulfur content in liquid hydrocarbons using Monochromatic Wavelength Dispersive X-ray Fluorescence (MWDXRF) spectrometry.
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. This value is an important indicator of the early stages of lipid oxidation and rancidity.
This test method measures the oxidative stability of fats and oils by determining the induction period at which oxidation rapidly accelerates. It does this by heating the sample under a stream of air and monitoring conductivity changes in the downstream water as volatile oxidation products form.
This XRF-based method utilizes an X-ray fluorescence (XRF) instrument for total chlorine elemental analysis in crude oil. Although XRF inherently measures total chlorine, a hot water extraction sample preparation step allows for differentiation between organic and inorganic chlorides.
This test method is a standardized procedure to measure the p-Anisidine value, which quantifies secondary oxidation products—mainly aldehydes—in oils and fats. This value indicates the extent of oil deterioration beyond primary oxidation measured by peroxide value.
This test method is an official method from the American Oil Chemists’ Society (AOCS) used to determine moisture and volatile matter in animal and vegetable fats and oils using a simple air oven drying technique. This gravimetric method is widely used for routine quality control. A known weight of sample is dried in an oven… Continue reading Moisture – 130°C [Oil]
