The stable ethanol aqueous solution, and its production mannered null ethanol

摘要

PROBLEM TO BE SOLVED: To provide zein-stabilized ethanol aqueous solution maintaining homogeneously transparent condition for a long time without causing gelatinization, and stable as a raw material solution such as a coating agent, a binder agent or the like.;SOLUTION: The zein-stabilized ethanol aqueous solution where ethanol aqueous solution having an ethanol concentration of ≥75 mass% but 90 mass% contains 5-20 mass% of zein, and causes no gelatinization at room temperature for 3 or more months. A method for producing the zein-stabilized ethanol aqueous solution comprises leaving the zein ethanol aqueous solution obtained by adding zein fine powder to the ethanol aqueous solution having ethanol concentration of ≥75 mass% but 90 mass% so as to have a content of 5-20 mass% and stirring the mixture at room temperature, and containing lees at rest, isolating supernatant liquid obtained after the lees are settled down, and causing no gelatinization at room temperature for 3 or more months.;COPYRIGHT: (C)2006,JPO&NCIPI
