Abstract
Zein is extracted from maize proteins with an aqueous alcoholic solvent to which is added an alcohol-miscible organic solvent for maize oil and colouring matter, which is a non-solvent for zein, the resulting extract being treated with further auxiliary solvent, and the zein solution separated from the solvent layer containing oil and colour. Lower aliphatic alcohols such as ethyl or methyl alcohol containing up to 20 per cent or more, preferably 7-8 per cent, of water may be used for the extraction, the auxiliary solvent being, e.g. toluol, benzol, xylol, chlorinated hydrocarbons, or aliphatic hydrocarbons. One part of toluol to two of alcohol may be used without separation of the mixture into two phases. The extraction is preferably effected below 70 DEG C. with a final pH above 6 as in Specification 492,599. The extract, preferably without concentration, is treated with further auxiliary solvent sufficient to cause separation into an alcoholic zein solution and an oil and colour solution layer which is removed. The zein solution may be further concentrated and purified by repeating the treatment. In an example, ground gluten meal is mixed with ethyl alcohol, toluol, and caustic soda solution at 60 DEG C. The extract which has a pH of 6,5, is decanted and extracted thrice with toluol. Zein is recovered from the concentrated alcoholic solution which separates.
