Patent number: 8124160Abstract: A process and apparatus for a method for reducing the amount of acrylamide in thermally processed foods. This invention permits the production of foods having significantly reduced levels of acrylamide. The method relies on the manipulation of various unit operations used in the production of food products, particularly the washing and cooking unit operations. For example, the washing unit operation can be modified to provide a contacting step at an increased time and temperature, and adding components such as calcium chloride and L-cysteine to an aqueous solution used for the contacting. The cooking unit operation can be modified by dividing it into at least a higher-temperature first heating step and a lower-temperature second heating step in order to avoid the high-temperature/low-moisture conditions most favorable for acrylamide formation.Type: GrantFiled: October 31, 2005Date of Patent: February 28, 2012Assignee: Frito-Lay North America, Inc.Inventors: David Lawrence Barry, Colin Jeffrey Burnham, Pravin Maganlal Desai, Ponnattu Kurian Joseph, Henry Kin-Hang Leung, John Richard Masson, V. N. Mohan Rao, Robert William Saunders, James William Stalder, Michael Grant Topor

Publication number: 20080182003Abstract: The present invention discloses formulations for sheeted, baked fruit and vegetable chips that have a light, crispy texture similar to a potato chip. The ingredients are combined with water and oil to make a dough, which is then sheeted and cut into pieces. The pieces are baked to produce vegetable and fruit snack chips.Type: ApplicationFiled: January 31, 2007Publication date: July 31, 2008Inventors: Rosemary Shine Baker, Brenda K. Cremer, Thomas George Crosby, Henry Kin-Hang Leung, Bridget Manis, Carla Mejia, Kelly Sam Miller, Nancy J. Moriarity, Jason Thomas Niermann, Timothy F. Root, Mark W. Sheppard, Jim Stalder, Beverly L. Waters, Jo Ellen Wayne

Patent number: 7267834Abstract: In fabricated, thermally processed snack foods, the addition of one of a select group of amino acids to the recipe for the food inhibits the formation of acrylamide during the thermal processing. The amino acid can come from the group of cysteine, lysine, glycine, histidine, alanine, methionine, glutamic acid, aspartic acid, proline, phenylalanine, valine, and arginine and can be a commercially available amino acid or in a free form in an ingredient added to the food. Amino acids can be added to fabricated foods at the admix stage or by exposing raw food stock to a solution containing a concentration of the amino acid additive.Type: GrantFiled: February 21, 2003Date of Patent: September 11, 2007Assignee: Frito-Lay North America, Inc.Inventors: Vincent Allen Elder, John Gregory Fulcher, Henry Kin-Hang Leung, Michael Grant Topor
