Effect of Cottonseed Oil on Discoloration of Cold Storage Eggs

Abstract

THE property of cottonseed meal when fed to laying hens to produce olive-colored yolks in cold stored eggs was reported in 1917, by Lamon and Lee and the property to produce pink whites by Sherwood in 1931. The olive color was reported by Heywang, Bird and Altschul (1955) to be caused by free gossypol, and the pink color was reported by Masson, Vavich, Heywang and Kemmerer (1957), and by Shenstone and Vickery (1959), to be caused by propene ring fatty acids. The observations by Kemmerer, Heywang and Vavich (1961), that sterculic acid enhanced gossypol discoloration in eggs indicate, but do not show definitely, that the propene ring fatty acids in cottonseed oil may have the same effect.The work reported in this paper shows definitely that cottonseed oil has an enhancing effect on the property of gossypol t o cause olive discoloration in cold stored eggs and itself to cause …
