Regular potato starch contains two constituent types of molecules: amylopectin (80 percent), which is more useful as a
polymer for industry, and
amylose (20 percent) which often creates problems as
starch retrogradation, so must be
modified with chemical reactions which can be costly. After two decades of research efforts, BASF's
biotechnologists using
genetic engineering succeeded in creating a potato, named "Amflora", where the gene responsible for the synthesis of amylose had been turned off, thus the potato is unable to synthesize the less desirable amylose. Amflora potatoes would be processed and sold as
starch to industries that prefer waxy potato starch with only amylopectin. Amflora is intended only for industrial applications such as
papermaking and other technical applications. Europe produces more than two million metric tons of natural potato starch a year, and BASF with its Amflora product hoped to enter into this large market.
Other possible uses According to
The New York Times, BASF has a second application pending for use of Amflora's
potato pulp as
animal feed. == Political disagreements ==
