This patent pertains to a method of producing a waxy maize starch derived from a plant which is heterozygous for the recessive sugary-2 allele by interplanting waxy maize seed which is homozygous for the dominant sugary-2 allele and waxy maize which is homozygous for the recessive sugary-2 allele, one hybrid being male sterile. The maize is harvested and processed together to obtain starch with excellent low temperature and freeze-thaw stability, high pasting temperature, and intact granules.

Method of grain production for heterozygous waxy sugary-2 maize

A novel method of producing maize grain with desirable functionality has been developed involving planting two different maize hybrids within the same field. The two maize hybrids are planted in alternating blocks of rows. One hybrid is male sterile such that the second hybrid provides pollen for the entire field. This leads to blocks of two separate types of grain which may be harvested and processed separately.

Grain production method for maize starch with novel functionality

Compositions, particularly foodstuffs, were thickened by the inclusion of an effective amount of a stabilized waxy potato starch, particularly a stabilized, crosslinked waxy potato starch, more particularly a hydroxypropylated waxy potato distarch phosphate. Compositions which include the starch may be thickened using less starch than if other starches were used. Foodstuffs prepared using the starch were improved in that they have better flavor, texture, and appearance.

Stabilized or stabilized, crosslinked waxy potato starch

The present invention is directed to a waxy maize starch derived from a single plant which is heterozygous for the recessive sugary-2 allele. Such starch has excellent low temperature and freeze-thaw stability, a relatively high peak viscosity, a relatively high pasting temperature, and intact granules. The starch is useful in a wide variety of food, pharmaceutical, and industrial applications.
