Reaction Steps

Twenty-five grams of lethicin and eleven grams of 9WR food grade potassium stearate (Sold by WITCO Company) is admixed with 7854 grams of 95% ethanol (95% ethanol is comprised of 95% by weight ethanol and 5% by weight water) to form an ethanol-stearate solution. Ten grams of sodium laurel sulfate (NF grade) is mixed with eleven hundred grams of water to form an aqueous sulfate solution. The aqueous sulfate solution is mixed with the ethanol-stearate solution to form an ethanol-stearate-sulfate solution. The 1000 grams of zein powder of Example 1 is mixed with the ethanol-stearate-sulfate solution to produce ten thousand grams of a zein-alcohol solution. 9000 grams of a 90% isopropyl alcohol solution to produce a zein-alcohol solution. The zein-alcohol solution is stirred for about five to ten minutes, or until the zein is completely dissolved. The resulting zein-alcohol solution is somewhat viscous, has a pH of 6.8 (the pH is typically in the range of 6.5 to 7.0) and has a light amber color.
