High‐Amylose‐Corn — eine vielversprechende Entwicklung in den USA
1960
Tegge, G.
Through investigation of its general and technically valuable properties, amylose gains a steadily rising economic interest. As, however, the production of pure amylose by fractionation of starch is unprofitable on an industrial scale, comprehensive trials were made in USA to raise the amylose content of corn starch by genetic methods as far as possible. As a result of these trials there are today already available certain quantities of a socalled high‐amylose‐corn with about 55 to 60% amylose in the starch for industrial research. The maximum amylose content obtained up to now by means of cultivation is 82% of starch. The technically interesting properties of starch with high amylose content mostly result from its chemical and structural similarity to cellulose and correspond to a very great measure to those of analogously composed amylose‐amylopectin mixtures. Excellent possibilities for application of starches rich in amylose and their derivatives arise from their good film and fibre forming properties. Excellent surface adhesion, elasticity and moulding capacity of the products obtainable from starch rich in amylose and its derivatives, enable the production of packing materials, special papers and perhaps textiles as well as plastic masses. Easy solubility and good digestibility of films from non‐derivatized starch with a high content of amylose can open new possibilities for application.
