Abstract: Using potato starches in Western Hubei province as material,the cold-water-soluble potato starches was processed by microwave treatment combined with 1,3-propanediol. The optimized technological conditions by orthogonal test L9(34) are as follows: water-propanediol ratio(V/V) 1:1,extracting time 17.0 min by microwave,and starch milk concentration 12%(W/V). The solubility of the obtained cold-water-soluble potato starch is 84.0%.

Key words: cold-water-soluble, potato starch, microwave treatment, 1,3-propanediol
