Abstract
In the extraction of alcohol-insoluble casein from seeds with a solution containing alkali, water and less than 40 per cent of water-miscible organic solvent as in the parent Specification, the seeds are treated with at least part, preferably all of the organic solvent, before treating with the alkali. The water may first be added to promote swelling, then the solvent, and finally the alkali, for example to a pH of 8.5-9.5. After standing for about 1 hour, the solution is removed as by centrifuging. A spinning solution may be formed directly or as a subsequent step. In examples, oil-free earth-nut meal is mixed with methylated spirits, acetone or methyl alcohol, and water, and after 1 hour 20 per cent caustic soda added. After standing for 2 hours, or overnight, the top liquor is removed, and protein precipitated with SO2. Commercial meal is treated similarly using a larger amount of alkali. Castor beans, freed from oil with acetone, are similarly mixed with ethyl alcohol and water, caustic soda added to a pH of 11.3, extracted for 48 hours, and the extract precipitated with sulphuric acid.
