Patent GB-785476-A (GB)
Title: Improved casein
Inventor: DODD ROBERT
IPC: D01F4/00
Filed: 1955-04-13
Abstract: The properties, i.e. opacity, colour, of casein obtained from animal or vegetable sources are improved by alternately washing the precipitated and coagulated protein with water at different temperatures in the presence of a surface-active agent, which may be added prior to the coagulation, so that the coagulate swells during one washing and contracts during the next washing.  The coagulate and whey are heated at a rate of increase of temperature not greater than 1 DEG  C. per minute to a temperature such that the coagulate may be handled but below that at which the coagulate becomes rubbery or stringy in texture or coagulates into large masses, e.g. 60 DEG  C., and is separated from the whey as quickly as possible.  The coagulate is then washed with water at 40-50 DEG  C., separated from the wash water, washed with water at a temperature below 20 DEG  C. and separated therefrom, the sequence being repeated a plurality of times.  Suitable surfaceactive agents are anionic, cationic, or non-ionic agents, the latter class being capable of forming water-soluble complexes with calcium and other heavy metals in which the metal is present in a unionized form, e.g. alkylated phenol ethylene oxide condensate, condensates of long-chain fatty alcohols and ethylene oxide which possesses a polyethylene glycol chain.
