  • Patent number: 5676994
    Abstract: 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.

Preferably a color development and sealing section has upper and lower burners which heat the food and the heat from these burners also pass the entire length of the cooking chamber before being exhausted. Also preferably steam or a water spray is used to regulate the humidity and this may be regulated in several different sections of the cooking chamber.

  • Patent number: 5534285
    Abstract: Reduced calorie, chemically leavened batters for the production of cake-type products are disclosed which incorporate preformed expanded liquid or gel mesophase emulsifier products so as to permit substantial reduction in high calorie components (e.g., shortening and sucrose) while giving organoleptically acceptable final cakes. The emulsifier products are preformed by initially mixing an emulsifier (preferably a polar and hydrophilic emulsifier such as a sucrose ester) with water, followed by optional heating and cooling to form the emulsifier product. The batters contain up to about 50% (flour weight basis) sweetening agent, which advantageously includes a high potency sweetener together with a minor amount of sucrose. A variety of bulking agents such as polydextrose can be used to give appropriate structure to the final cakes.

  • Patent number: 5529798
    Abstract: This invention is a barbecue type grill that can be used either indoors or outdoors. By disposing a convertible drip pan that can be opened and closed between the food supporting rack and the cooking heat source, rapid preheating can be accomplished as well as searing of desired food products, followed by closing of the drip pan to prevent unwanted flare-ups caused by juices dripping from the food being cooked. This closing of the drip pan allows the food to cook slower than over direct heat which allows the food to retain more juices when done. This invention overcomes the slow preheating and slow initial cooking inherent in the prior art using a solid impervious drip pan. Also, since different types of heat sources can be used in conjunction with the present invention, the problem of the bottom of the housing rusting out in the area adjacent the round burner below the heat deflecting plate is effectively eliminated.

  • Patent number: 5529797
    Abstract: A plurality of rolls of pliable backing material are fed through guides in which the configuration of the backing material is converted from flat to generally U-shaped strips. Unbaked dough is deposited into the strips as they feed forwardly toward a baking oven. The strips, filled with unbaked dough, are moved through the oven at a rate which enables the oven heat to bake the dough. When the strips, filled with baked dough, emerge from the oven, they are intermittently severed, advantageously by a high pressure stream of water, to create discrete baked products. These products are then conveyed for a time and distance sufficient to permit cooling, and are thereafter wrapped.

  • Patent number: 5512312
    Abstract: An oven for cooking and browning foods has heated, radiant walls. Heat may be supplied by a gas burner flame in a plenum behind the walls, with products of combustion thus being isolated from the food in the oven chamber. In one embodiment food products are continuously conveyed through the oven chamber and are either cooked or simply browned in the oven by the radiant wall heat. Fats and other materials rendered from the food products, if not fully incinerated in the oven chamber, may be transferred along with exhaust air from the oven chamber to a separate combustion chamber, for incineration. Steam or other inert gas is introduced to the oven chamber to minimize oxidation and prevent flame. An alternative wall heating system uses electric resistance heat elements inside a thin ceramic wall. In another embodiment a web-like metal conveyor of a radiant wall oven is returned through the oven in order to heat the conveyor sufficiently to put grill stripes on a product being browned, such as meat.

  • Patent number: 5510127
    Abstract: Bread is produced in a bread maker by first mixing/kneading the bread ingredients into a dough, allowing the dough to rest and then kneading the dough for a second cycle. During both kneading cycles, a motor driving a kneading blade is repeatedly bi-directionally rotated with intermittent pulses to give a randomness to the flight of the dough. After kneading, the dough is fermented during a first rise cycle. Next, the dough is preheated and degassed before it is fermented for a second rise cycle. After rising, the dough is baked at a high temperature for proper browning of the crust and then the temperature is lowered to complete the baking of the bread. Lastly, the bread is cooled at a gradual rate by intermittently actuating a heater and a fan.

  • Patent number: 5505975
    Abstract: Meat such as poultry may be rapidly cooked in a closed and sealed pressure vessel subjected to a mixture of superheated steam and superatmospheric compressed air at a temperature of least 400.degree. F. and at an internal chamber pressure of at least 15 psig fed from an air compressor through a heat exchanger. Water is mixed with the heated superatmospheric compressed air such that a mixture of superheated steam and superatmospheric compressed air is created prior to mixture entry into the interior of the pressure vessel. Preferably, meat is cooked rapidly at a temperature within the chamber in the range of 400.degree. F. to 600.degree. F. and at pressures ranging from 15 to 150 psig. A pressure relief valve coupled to the pressure vessel exhausts the mixture of superheated steam and superatmospheric compressed air to maintain the desired gas pressurization within the chamber.

  • Patent number: 5489444
    Abstract: Embodiments of a potato-on-a-stick, and methods for making the potato-on-a-stick, are disclosed. The potato-on-a-stick includes a pre-cooked potato, which is prepared by partial baking, an interruption in cooking to cool the potato, and then blanching, which allows a stick to be inserted without breakage of the potato and which causes the potato to adhere to the stick and hold the stick in place in the potato throughout further handling, freezing, thawing, finish-cooking, and eating. In one embodiment, the method of making the potato-on-a-stick product starts with the baking process for potato boats, in which whole potatoes are partially baked, cooled, cut, and scooped-out. The scooped-out potato centers are then blanched and cooled, and a wooden stick is inserted and secured by the adhesiveness of the potato contacting and holding the stick. The invented method produces a potato product which has a secured stick and has an uncrumbly, unbreaking texture and yet a pleasant, soft and palatable texture.
