| Abstract: | Objective] The extraction technology of the pigment and ethanol-soluble protein in corn, suitable for the industrial production, was researched. Method] The gluten, by-products from the corn starch production, being taken as raw materials, and the ethanol being taken as extraction dose, the best condition of the yellow pigment and gliadin extracted from corn was experimented with the orthogonal test. Result] The best extraction condition of the yellow pigment from corn was the temperature, 55 ℃; the extraction time, 2 factors affecting the extracting result was the ethanol volume > extraction time > pH value > temperature. The best extraction condition of gliadin was the extraction temperature, 50 ℃; the alcohol volume, 70%; the ratio of solid-liquid, 1:4; the soaking time, 6 hours; the pH value, 5.0; and the order of the factors affecting the extracting result was the soaking time > ethanol > temperature > alcohol > pH value. Conclusion] The basis of the industrial production of yellow pigment and gliadin extracted from corn was provided. |
