- Abstract
This paper studied the extraction and purification of corn bran as well as its oxidation resistance from an industrial chain perspective in order to improve the utility value of corn and increase the economic benefits of corn processing enterprises, which had great and far-reaching significance for the value creation of the corn industry. The microwave-assisted waterextraction and alcohol-precipitation method was applied for extraction of polysaccharide from corn bran. Then, the extracted polysaccharide was processed with Sevag method for deproteinization, dialysis method for removal of small molecular impurities and finally Sephadex G-75 chromatography for separation and purification. Thus, the oxidation resistance of the purified polysaccharide extracted from corn bran was studied. The results showed that corn bran polysaccharide CSP ? contained galactose, glucose, arabinose, xylose, wherein the content of glucose was the highest. Besides, no nucleic acid and small amount of protein was found in corn bran polysaccharide CSP?. Corn bran polysaccharide CSP ? had varying degrees of scavenging effect on hydroxyl radical, DPPH ? radical and superoxide anion free radical, of which the scavenging effect on hydroxyl radical was not obvious. If results of this study can be applied to the actual corn industrial chain, not only can the corn bran be turned into useful resource but also the industrial value creation can be improved through the development of high value-added products, which can bring a very broad market prospect and remarkable economic benefit.
