Improved Monomolecular Fat Film Method for Determination of Yolk in Egg Albumen
Keyword(s):
Abstract The monomolecular film method can be simplified by an improved quantitation procedure. Following the extraction of the fat from the albumen and subsequent evaporation, the redissolved sample is applied to a round glass plate containing 1 in. pH 5 acetic acid solution topped by a film of oxidized oil sufficient to exhibit a color of third order green. The sample aliquot is dropped from a 100 μL Hamilton syringe directly at the center of the oil surface. A circular pattern results. The diameter of the pattern is measured in centimeters with a ruler placed under the glass plate. The area of the pattern is then calculated by the formula for the area of a circle.
