Abstract
FROM previous work1,2 it is known that egg albumen, in common with other protein solutions, exhibits dielectric dispersion at megacycle frequencies and microwave frequencies due to the relaxation of the protein and water molecules, respectively. The measurements recorded here, however, indicate that there is another small dispersion region occurring at tens and hundreds of megacycles between the two main regions which is similar to the effect reported by Schwan3 for the case of hæmoglobin.
