ABSTRACT:
The invention concerns a method for obtaining plants producing modified polysaccharides (such as starch or glycogen), said modified polysaccharides extracted from said plants and the products prepared from said modified polysaccharides. The invention also concerns a method for obtaining modified starch or modified glycogen which consists in contacting a starch or a glycogen with an α-1,4 glucanotransferase enzyme.
