Patent number: 6197354Abstract: A method for processing fresh garlic which will not leave an unpleasant odor after having been digested is disclosed. The fresh garlic can be peeled, unpeeled, minced or chopped prior to processing. Garlic is composed of many tiny micrograins containing aromatic oils that are responsible for its strong odor. It has been determined with the correct processing of the fresh garlic by microwaving an aqueous or water soluble solution of fresh garlic, that most if not all of the tiny micrograms can be ruptured such that the aromatic oils can be easily neutralized by digestion. Solutions that are useful in practicing the invention are pure boiled water, boiled water and vinegar, boiled water and lemon juice, and lemon juice in natural concentration. The microwave radiation is useful in rupturing the micrograins without a total cooking of the garlic which would remove its fresh flavor and texture. In addition, edible salts can also be added during the process to adjust taste or as a preservative.Type: GrantFiled: May 25, 1999Date of Patent: March 6, 2001Inventor: Tony S. Zaboli

A drink container includes a tubular liquid inlet in fluid flow communication with the drink medium container. The liquid container is in fluid communication with the drink container such that when liquid in the liquid container is heated, the liquid can flow upward from the liquid container through the tubular member, filter apparatus, and through the tubular liquid inlet into the drink container. The liquid container includes a double wall construction to maintain the temperature on an outer surface thereof at a relatively low level.Type: GrantFiled: February 17, 1998Date of Patent: May 11, 1999Assignee: HP Intellectual Corp.Inventor: Patrick B Nolan

Patent number: 5884417Abstract: The generation of volatiles from liquid or solid materials is enhanced and accelerated by exposure to microwave radiation. Normally the energy transfer is effected preferentially toward the liquid or solid materials over the generated gaseous volatiles. Sufficient energy is provided at a selected rate that enhances the generation of volatiles to effect removal as vapor or to produce a pressurized vapor phase. Flow-through separations from a matrix having a microwave-absorbing liquid component are conducted by exposing to microwave radiation to vaporize this component and processing the vapor either by flowing through a selective permeable membrane, or by enclosing the vapor and matrix in a confined space and flowing matrix through a selected separation medium, and recovering residual matrix. These separations are particularly useful in analysis contexts.Type: GrantFiled: September 11, 1997Date of Patent: March 23, 1999Assignee: Her Majesty the Queen in Right of Canada, as represented by the Minister of the EnvironmentInventor: J.

Patent number: 5858430Abstract: A food preservation and disinfection method utilizes oxygen-enriched chilled water that is applied to the food product as ice formations or alternatively is sprayed on the food product to form a frozen surface glaze. Upon thawing the frozen food product, an oxidative reaction occurs under the influence of a temperature dependent catalyst accelerant. The oxygen enrichment is accomplished by dissolving ozone and hydrogen peroxide, in combination or independently, in chilled water.Type: GrantFiled: November 3, 1997Date of Patent: January 12, 1999Inventor: Felix W. Endico

Patent number: 5853726Abstract: A process for extraction and fixation of aromas on a non-aqueous substrate, according to which aromatic plants, seeds, or fruits and a substrate such as a fat or oil are placed in a treatment zone and microwave radiation is produced in the treatment zone so as to heat primarily the aqueous parts of the plants rather than the components of the substrate, a machine to implement the process of the invention which comprises primarily a treatment vessel and a microwave radiation apparatus, and a product obtained by said process.Type: GrantFiled: July 21, 1995Date of Patent: December 29, 1998Inventor: Pierre Chevereau

Patent number: 5846585Abstract: The process for increasing the bulk of a food having a decreased bulk in the present invention comprises applying a means of internal vibration heating such as a microwave oven to a food having a decreased bulk, which has been prepared by subjecting a porous food comprising a cereal flour and water, such as breads, to a treatment such as compression, and has maintained the thus decreased bulk. The food of which the bulk has been increased by such a way has a bulk comparable to the one immediately after baking and exhibits excellent taste and feelings during eating.Type: GrantFiled: November 6, 1996Date of Patent: December 8, 1998Assignee: Kao CorporationInventors: Hisao Ohmura, Tomoko Fukunaga, Naoto Kudo, Yukitaka Tanaka, Naoki Hosoya, Masaru Sakata, Masami Shimizu, Yasumasa Ohki, Manabu Sato, Masanori Komikado, Takao Hibi, Tomohiro Fukita, Daisuke Shiiba

Patent number: 5843504Abstract: The sausage strand is extruded onto a belt and carried through a brine shower system for about 40 seconds. The brine is sprayed through nozzles onto the sausage while traveling on the belt. The sausage is turned several times during the shower to insure even brine distribution. The conveyor speed is controlled to match the speed of the extruder thereby preventing stretching of the product as it is being extruded. The conveyor provides exact motion control of the sausage rope and the dwell time in the brine shower can be exactly regulated. Since the conveyor system is open it lends itself to easy cleaning and visual inspection. The conveyor consists of a frame which supports the conveyor system, the brine shower system, air knives and the infrared heater. The brine shower system is composed of a drip pan, a brine tank, a centrifugal pump and a plumbing/brine distribution network. The centrifugal pump conveys the brine from the tank through the brine distribution network.Type: GrantFiled: October 15, 1996Date of Patent: December 1, 1998Assignee: Townsend Engineering CompanyInventors: Jos Kobussen, Mart Kobussen, Jaap Kobussen
