| abstract | 1,264,744. Increasing the swelling temperature of potato starch; hydroxypropyl starch. PENICK & FORD Ltd. 15 April, 1970 [19 May, 1969 (2)], No. 17979/70. Heading C3U. A process for treating potato starch in an aqueous suspension to effect an increase in the swelling temperature to improve the paste and gel properties, involves forming a stirrable aqueous suspension of potato starch at a pH in the range 5À5-8À0, and maintaining the temperature of the suspension below the swelling temperature of the starch and above 100‹ F. for a time sufficient to cause an increase in the swelling temperature of the potato starch. Thus, the suspension may be held successively at a temperature 5‹ to 10‹ F. below the attained swelling temperature, e.g. in the range 100- 125‹ F., for at least one hour and gradually increased to 140‹ F. The treated potato starch may be reacted, in aqueous suspension, with propylene oxide in the presence of an alkaline catalyst (NaOH or KOH, with Na 2 SO 4 ) to give hydroxypropyl starch in water-washable, granule form (5-30% hydroxypropyl content). |
