Abstract
An apparatus and method for quantitatively measuring volatiles, solids and solvent extractables is described which provides rapid and accurate determinations using microwave heating, electronic balance weighing and solvent extracting of solubles. The method involves subjecting a weighed sample to microwave drying for a preselected time, reweighing to obtain the dry weight and determine volatile loss, solvent extracting the dried sample to determine fats, oils and other extractables followed by final measurement of residual solids. The apparatus is preferably automated to sequentially actuate the required weighing, microwave heating, solvent extraction, redrying, reweighing and calculation of the percentages of volatiles, solvent solubles and solids. The apparatus and method are particularly suited for analytical uses in the food and dairy industries.
