Patent number: 5476675Abstract: A process is disclosed for preparing a substantially dry edible flavor fiber product by admixing water, a powdered flavor, a binder and fiber together and extruding the resulting mixture. The process can be carried out by first admixing a powdered flavor material with a fiber to form a flavor-fiber and mixture, then the flavor-fiber mixture is introduced into an extruder where water is simultaneously introduced and the resulting composition, containing water, fiber and flavor is extruded to form a product. The flavor fiber product can be an instant beverage, such as chocolate.Type: GrantFiled: November 22, 1994Date of Patent: December 19, 1995Assignee: International Flavors & Fragrances Inc.Inventors: Wen C. Lou, Chee-Teck Tan, Lewis G. Scharpf, Jr., Joseph Panarisi

Patent number: 5124161Abstract: The present invention relates to a filled, elongate half product which can be expanded (i.e., puffed) when subjected to microwaves. The half product comprises an elongate outer casing formed from a dough containing a cereal material, water, and, optionally, starch, microwave absorptive materials (e.g., sugar or salts), and emulsifiers. Within the outer casing is a filling formed from an edible oil and flavoring. The half product of the present invention is prepared by mixing the ingredients which form the dough, cooking the dough at an elevated temperature and pressure to gelatinize the starch, venting the cooked dough to reduce its moisture content and temperature, cooling the cooked dough, coextruding the cooked dough and filling material to form a filled half product, and cutting the resulting extrudate cross-sectionally.Type: GrantFiled: June 7, 1989Date of Patent: June 23, 1992Assignee: Nabisco Brands, Inc.Inventors: Bernhard H. van Lengerich, Wen C. Lou

Patent number: 4911939Abstract: Microwave-baked cookies can be prepared from a particular cookie dough composition. This cookie dough composition is shelf-stable and should contain gluten, pregelatinized starch and high fructose corn syrup. After being prepared, the cookie dough is formed into individual cookie pieces and prebaked for a short period of time in order to shape the cookie and to provide a gluten-containing skin on the cookie's surface. The prebaked cookie is then packaged and sealed. In this state, the prebaked cookie dough pieces have an extended shelf life. When the cookie dough is to be microwave-baked, it is placed in a microwave oven, optionally covered at least in part by a microwave susceptor material, and the baking process initiated for the instructed time. The result is a hot baked cookie having the taste and texture of a home-baked cookie.Type: GrantFiled: October 21, 1988Date of Patent: March 27, 1990Assignee: Nabisco Brands, Inc.Inventors: Wen C. Lou, Richard D. Fazzolare

Patent number: 4752482Abstract: A process is disclosed for producing a heat-stable, yeast fermented malt reaction flavor concentrate which is of low volatility. The process involves preparing a malt flour such that it has sufficient fermentable sugars, fermenting the malt flour with yeast at a temperature of from about 10.degree. C. to about 60.degree. C. for a period of time of from 1/2 to 6 hours and heating the fermented malt produced by the fermentation to inactive the yeast and develop flavors. The yeast fermented malt derived food flavorant may be incorporated into a foodstuff, preferably a ready-to-eat cereal or baked good at a level of from 0.3 to 5% by weight.Type: GrantFiled: February 18, 1987Date of Patent: June 21, 1988Assignee: General Foods Corp.Inventors: Charles V. Fulger, Wen C. Lou

Patent number: 4568550Abstract: This invention prepares a fully cooked extruded flour-based product with a texture, aerated structure, cohesiveness, appearance and rehydration characteristics of a fully baked flour-based product by: feeding a flour, a gas forming agent, and water into an extruder in amounts effective to prepare a dough having a moisture content within the range of 20 to 40%; mixing and kneading the flour and water to prepare a homogeneous dough; and extruding the dough while subjecting the dough within the extruder to cooking temperatures within the range of 140.degree. F. to 250.degree. F. (60.degree. C. to 120.degree. C.) while under pressures and low shear conditions and for a period of time effective to set the protein and to partially gelatinize the starch in the flour while maintaining the starch granule integrity.Type: GrantFiled: March 11, 1985Date of Patent: February 4, 1986Assignee: General Foods CorporationInventors: Charles V. Fulger, Charles R. Lazarus, Wen C. Lou, Charles T. Stocker, Chia-Chi Tu

Patent number: 4521436Abstract: A composition useful for the production of a rehydratable rice product and a method of making such product. The composition includes ungelatinized 90.0 to 99.5 by weight rice flour, 0.2 to 5.0 percent of an aeration agent, 0.1 to 3.5 percent of an emulsifier, and, optionally, up to 1.5 percent by weight of an edible gum. The composition is mixed with water and extruded at temperatures not in excess of 220.degree. F. and dried to make a rehydratable rice product. The extrudate is sized, preferably after drying, into lengths simulating the lengths of rice grains. The product is rehydratable in boiling hot water in 1 to 4 minutes and is particularly suitable for making a rice pudding, in 3-6 minutes.Type: GrantFiled: July 27, 1983Date of Patent: June 4, 1985Assignee: General Foods CorporationInventors: Wen C. Lou, Charles V. Fulger

Patent number: 4450177Abstract: A frozen bread dough which can be prepared from the freezer to a finished baked loaf within about one hour has been accomplished by using a novel process. Because the bread dough is yeast leavened, desirous yeast-leavened flavor and aroma is obtainable. The dough maintains its shelf-life stability through the addition of hydrophilic colloids, film-forming proteins and surfactants.Type: GrantFiled: September 26, 1983Date of Patent: May 22, 1984Assignee: General Foods CorporationInventors: Robert W. Larson, Wen C. Lou, Vivian C. DeVito, Karen A. Neidinger
