of starch granules with respective quantities of an alcohol and a strong base to swell the granules and convert the starch to form having increased cold water solubility the process can be used on waxy high amylose tuber and normal starches the resulting cold water swelling soluble starch preferably exhibits about 50 to 94 solubility in cold water application_number US 60091090 A description waxy corn starch a starch containing essentially no amylose is treated with a solution containing about 4 7 to about 8 7 parts of ethanol about 0 24 to about 0 37 parts naoh and about 2 1 to about 3 2 parts water the resulting cold water soluble swelling starch gives about 50 to 94 solubility in cold water example i describes the most preferred treatment method native waxy corn starch 1 part by weight dsb was suspended in absolute ethanol 6 9 parts by weight aqueous naoh solution 2 73m 3 4 parts by weight was added slowly under mechanical stirring after the addition of naoh was complete the reaction mixture was stirred for 10 additional minutes and drained the starch was then washed with an aqueous ethanol solution i 75 alcohol by volume prepared by mixing 3 volumes of absolute ethanol and one volume of water drained and resuspended in an aqueous ethanol solution ii 80 alcohol by volume and neutralized with hcl 2m in absolute ethanol the starch was subsequently washed twice with the aqueous ethanol solution i dehydrated with absolute ethanol and dried in a forced air.
