AN364: Rapid Determination of Total Fat from Dairy Products

Instrument Type: Automated Sample Prep

The U.S. Nutritional Labeling and Education Act of 1990 requires nutritional labels listing the content of saturated and unsaturated fats in food. Accurate determination of fat in certain foods is difficult due to the binding or entrapment of the fat by the matrix. Accelerated Solvent Extraction (ASE) is an automated extraction technique that significantly reduces extraction time and solvent consumption and yields equivalent results. In this work, fat was extracted from sour cream, cream cheese, coffee creamer, heavy whipping cream, and low-fat milk.

AN330: Accelerated Solvent Extraction (ASE) of the Organic Components of Granular and Liquid Detergents

Instrument Type: Automated Sample Prep

Organic solvent extraction is a standard technique in the detergent industry for isolation of organic components from inorganic matrices and separation of ionic and nonionic surfactants. For example, analysis of the alcohol-soluble portion of detergents is routinely performed to verify the integrity of the manufacturing process. Traditional extraction of this material is labor-intensive and uses large amounts of liquid solvent. With ASE, manufacturers can streamline the extraction process to quickly verify product quality and provide feedback information into the production cycle.
