| Abstract: | Corn zein has a good ability to form tough, hydrophobic, grease proof coatings Applications of zein in special food, pharmaceutical and biodegradable plastics have a potential prospect. With ultrasonic technology, the efficiency of decolour and extraction of zein from corn gluten meal(CGM) were studied When decolour process is carried out with absolute ethanol, at a ratio of liquid to solid as 6∶1(mL∶g) for 50 ?min with sonication, and zein is extracted at pH 12, a ratio of liquid to solid as 6∶1(mL∶g) with 80% ethanol for 30 ?min with sonication, the extraction rate and purity reach 27% and 88% respectively |
