Abstract: 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.

Abstract: An extruder die assembly and method for using same is disclosed which is designed for adaptation to a wide variety of commercial-grade extrusion devices common in the food industry. The extruder die assembly is inserted into an appropriate compartment within an extrusion device such that a first extrudate is directed down a coaxially aligned passageway within the forming section and combined with a fluid additive in the injection section whereupon the resulting food mass is compressed through a converging nozzle bore in the nozzle section to produce an extruded food product. The forming section and injection section are fabricated as a matching set.

Abstract: With the process for producing potato based expandable pellets, an intermediary product is manufactured that is capable of being stored for up to about six months. These pellets can be later expanded into a food product, particularly a potato based snack product that has improved flavor qualities and increased oil pick up. To form the pellets, a potato meal is passed through a twin screw extruder at a relatively low extruder rotational speed, which increases the residence time and the volume of bed pack in the extruder while decreasing shear. The extrudate produced is then split into ribbons that are subsequently perforated. These ribbons are then formed into shaped pellets.

Abstract: In the process of producing corn-based pellets, preconditioner steam and water addition, as well as extruder water or screw configuration and RPM, can be manipulated to precisely control the cook level, gelatinization, and moisture level of the meal during processing, and level of defects despite minor variation in the characteristics of the corn flour. Specifically, the preconditioner added steam-to-water ratio can be manipulated to effect cook, hydration, and partial gelatinization of the meal. In the extruder, lower extruder rotational speeds increase the residence time and increases cook. With the increase in residence time the volume of bed pack in the extruder increases. This can be reversed by adding water directly into the extruder, thereby decreasing the viscosity of the meal in the extruder. Product bulk density is changed by increasing and decreasing cook of the meal.

Abstract: In the process of producing masa based expandable pellets, preconditioner steam and water addition, as well as extruder water and RPM, can be manipulated to precisely control the cook level, gelatinization, and moisture level of the meal during processing, and level of defects despite minor variation in the characteristics of the masa flour. Specifically, the preconditioner added steam-to-water ratio can be manipulated to effect cook, hydration, and partial gelatinization of the meal. In the extruder, lower extruder rotational speeds increase the residence time and increases cook. With the increase in residence time the volume of bed pack in the extruder increases. This can be reversed by adding water directly into the extruder, thereby decreasing the viscosity of the meal in the extruder. Product bulk density is changed by increasing and decreasing cook of the meal.

Abstract: A method of extending the holding time for a cooked food under specified conditions of temperature and high relative humidity, and more specifically, a method of significantly extending the holding time for cooked chicken products for an additional period through controlling of the environment or atmosphere within a holding chamber without encountering any appreciable loss in the organoleptic, olfactory or textured qualities of the food. The chicken product is maintained in a holding chamber in an environment or atmosphere at carefully controlled dry bulb and wet bulb temperatures under conditions of a high relative humidity.
