Title: Method of treating egg whites to improve keeping and whipping qualities
IPC: A23L15/00
Filed: 1937-07-13
Abstract: 500,800. Treating egg whites to improve their keeping and whipping qualities. McCHARLES, C. H., and MULVANY, H. A. July 13, 1937, No. 19380. [Class 49] Egg whites are treated to improve their keeping and whipping qualities by adding to the liquid egg whites sufficient acid to bring the pH value to about 5À8, e.g. 0*15 per cent by weight of hydrochloric acid, agitating in vacuum, e.g. of 28 inches, at a temperature e.g. about 50‹ C., which is slightly below the coagulating point of the liquid egg whites until the hydrogen ion concentration decreases to a pH value of 7 or below, and finally drying, freezing or condensing. Sulphuric or tartaric acid may alternatively be used. Where the amount of acid used is increased, e.g. where 0'22 per cent of hydrochloric acid is employed, the acid is added in several portions with heat and vacuum treatment between, to enable the change in pH value to be obtained. When spray drying is employed, the acid is added in two or more stages, the material being each time brought to a pH value of about 5À8 and subjected to the heat and vacuum treatment, the agitation being omitted.
