Patent number: 5900496Abstract: A strain of Pseudomonas Sp. bacterium (NRRL B-18602) has been discovered which is capable of converting oleic acid to the novel compound, 7,10-dihydroxy-8-octadecenoic acid (DOD). The production of DOD is unique in that it involves a hydroxylation at two positions and a rearrangement of the double bond of the substrate molecule. The new multifunctional, long-chain aliphatic acid has potential utility as a plasticizer and as a source of intermediates in the synthesis of specialty chemicals.Type: GrantFiled: June 18, 1996Date of Patent: May 4, 1999Assignee: The United States of America as represented by the Secretary of AgricultureInventor: Ching T.

Patent number: 5882713Abstract: A stable and non-separable composition comprised of starch and a water-immiscible material can be prepared in the absence of external emulsifying or dispersing agents by thoroughly solubilizing an aqueous dispersion of the starch at elevated temperatures and incorporating the water-immiscible material into the non-retrograded starch under conditions of high turbulence. The resulting dispersions form soft gels that can be easily converted to pourable fluids by the application of heat. Upon drying, these dispersions yield solid compositions that are easily redispersed in water to form smooth, stable dispersions. These compositions are useful as thickening agents, suspending agents, waterproof coating materials, adhesives, fat substitutes, and seed coatings. They are receptive to the addition of a variety of other water-immiscible materials, such as volatile and essential oils, food flavorants, medicinals, waxes, agricultural chemicals, and the like.Type: GrantFiled: February 25, 1997Date of Patent: March 16, 1999Assignee: The United States of America as represented by the Secretary of AgricultureInventors: Kenneth Eskins, George F. Fanta

Patent number: 5689054Abstract: Single-gene, non-lethal mutations responsible for low phytic acid-containing seeds are selectable by means of a method for assaying seeds which are otherwise phenotypically, or nearly phenotypically, normal. Maize mutants having from 20% to 95% reductions in kernel phytic acid phosphorus compared to the wild-type, without any noticeable reduction in total phosphorus, were isolated by this method. Mutants obtained in accordance with the invention are useful for developing commercial, low phytic acid seed, plant lines.Type: GrantFiled: March 17, 1994Date of Patent: November 18, 1997Assignee: The United States of America as represented by the Secretary of AgricultureInventor: Victor Raboy

Patent number: 5676994Abstract: A stable and non-separable composition comprised of starch and oil can be prepared in the absence of external emulsifying or dispersing agents by thoroughly solubilizing an aqueous dispersion of the starch at elevated temperatures and incorporating the oil into the non-retrograded starch under conditions of high turbulence. The resulting dispersions form soft gels that can be easily converted to pourable fluids by the application of heat. Upon drying, these dispersions yield solid compositions that are easily redispersed in water to form smooth, stable dispersions that are nongreasy, yet slippery to the touch. These compositions are useful as thickening agents, suspending agents, fat substitutes, and seed coatings. They are receptive to the addition of a variety of water-immiscible materials, such as volatile and essential oils, food flavorants, medicinals, agricultural chemicals, and the like.Type: GrantFiled: July 24, 1996Date of Patent: October 14, 1997Assignee: The United States of America as represented by the Secretary of AgricultureInventors: Kenneth Eskins, George F.

Patent number: 5550177Abstract: Aqueous ambient temperature pastes and gels of starch and poly(ethylene-co-acrylic acid) are disclosed containing starch in an amount from about 2.5% to about 10%, by weight, of the paste or gel, and poly(ethylene-co-acrylic acid) in an amount from about 0.5% to about 20%, by weight, of the starch, the poly(ethylene-co-acrylic acid) content being sufficient to provide aqueous ambient temperature pastes having higher viscosities than the same ambient temperature pastes without poly(ethylene-co-acrylic acid) and to provide aqueous ambient temperature gels having different gel strengths from the same ambient temperature gels without poly(ethylene-co-acrylic acid). These pastes and gels are prepared by a method in which a starch and poly(ethylene-co-acrylic acid) mixture in an aqueous medium is cooked, preferably by steam-jet cooking, and the resulting starch-poly(ethylene-co-acrylic acid) solution/dispersion is cooled to ambient temperature with water retained in the solution/dispersion.Type: GrantFiled: February 28, 1992Date of Patent: August 27, 1996Assignee: The United States of America as represented by the Secretary of AgricultureInventors: George F.
