PFLANZEN MIT VERRINGERTER AKTIVITÄT IN ZWEI ODER MEHR STÄRKE-MODIFIZIERENDEN ENZYMEN

摘要

Disclosed is potato starch which, when in native form extracted from a potato plant, exhibits freeze/thaw stability such that a 1 %w/v aqueous suspension of the starch has an absorbance at 700nm wavelength of less than 1.2 units following 4 freeze/thaw cycles of freezing at -70 DEG C overnight and thawing at room temperature for at least 2 hours; together with a method of altering the starch content of a plant; and altered plants, especially altered plants which contain freeze/thaw stable starch. Further disclosed is waxy (i.e. low amylose) starch having reduced gelatinization onset and swelling temperatures.
