New and improved solutions of zein and method of making same

Claim 1

A METHOD OF MAKING A MIXTURE OF WATER WITH A ZEIN SOLUTION, WHICH CONSISTS IN DISSOLVING THE ZEIN INITALLY IN A SUBSTANTALLY ANHYDROUS GLYCOL WHICH IS A PRIMARY SOLVENT FOR ZEIN, SAID GLYCOL BEING SUBSTANTIALLY NON-VOLATILE AT 130* C. UNDER A PRESSURE OF 760 MM. OF MERCURY AND HAVING A CRITICAL PEPTIZATION TEMPERATURE WHOSE MAXIMUM IS MINUS 40* C. TO MAKE AN INITIAL SUBSTANTIALLY ANHYDROUS SOLUTION WHICH REMAINS CLEAR AND STABLE AT 21* C. FOR AT LEAST SIX WEEKS, AND THEN ADDING WATER TO SAID INITIAL SOLUTION, THE WATER BEING ADDED SUFFICIENTLY SLOWLY AND WITH SUFFICIENTLY VIGOROUS AGITATION TO BLEND WITH SAID INITIAL SOLUTION WITHOUT PRECIPITATION OF THE ZEIN, THE WEIGHT OF THE ADDED WATER BEING AT LEAST 10% OF THE WEIGHT OF THE MIXTURE AND BEING WITHIN THE WATER TOLERANCE OF SAID PRIMARY SOLVENT.
