Abstract: Using scanning electron microscope and X-ray diffraction, the granular morphology and crystal characteristics of fried naked oat starch were examined. At the same time, physicochemical properties and digestibility were also investigated. Compared with non-fried naked oat starch, the appearance and crystal characteristics of fried naked oat starch changed greatly; meanwhile, its amylose content, blue value, gelatinization temperature and swelling degree revealed an obvious decrease and the contents of SDS and RS were lower, whereas fried naked oat starch exhibited a significant increase in the transparence and solubility as well as higher RDS content. Furthermore, both the water separation rates of non-fried and fried naked oat starches were higher than 50%.

Key words: naked oat, frying, quality of starch
