  • Patent number: 6919547
    Abstract: Indentation patterns are scored in microwave packaging materials to enhance the baking and browning effects of the microwave packaging materials on food products. The indentation patterns provide venting to either channel moisture from one area of the food product to another, trap moisture in a certain area to prevent it from escaping, or channel the moisture completely away from the food product. The indentation patterns cause the microwave packaging material underneath a food product to be slightly elevated above the cooking platform in the base of a microwave. The indentation patterns lessen the heat sinking effect of the cooking platform by providing an air gap for insulation. Elevating the base of the microwave packaging material further allows more incident microwave radiation to propagate underneath the microwave packaging material to be absorbed by the food product or by microwave interactive materials in the microwave packaging material that augment the heating process.

  • Patent number: 6559431
    Abstract: A Microwave Cooking Tray and Sleeve Assembly comprises a tray for holding food to be cooked, a transparent heat seal covering the tray, and a sleeve designed to hold the tray. In order to cook the food in the tray, the assembly is placed in a microwave oven. During cooking, side vents on the tray channel steam out of the tray. Holes in the sleeve allow the steam to easily escape the box after passing through the vents in the tray. After a short period of cooking in the microwave oven, the tray is removed from the sleeve, the heat seal is removed from the tray, and the food in the tray is ready to eat.

  • Publication number: 20030039726
    Abstract: A method of treating a food product includes packaging the food product in a modified atmosphere, removing oxygen from the modified atmosphere and irradiating the food product, such that the oxidation of the food product is impeded for a predetermined period of time after irradiating the food product. The removal of oxygen can be accomplished by packaging the food product in a substantially oxygen-free modified atmosphere using a multi-layered packaging material in which the outer layer is an oxygen-impermeable layer and the inner layer is an oxygen-permeable layer. After completion of the irradiation process, the outer oxygen-impermeable layer can be removed, allowing oxygen to enter the package. In an alternative embodiment, an oxidant-reactive chemical substance is applied to the food product prior to irradiating the food product to scavenge oxidants, such as free radicals, from the package atmosphere.

  • Patent number: 6509047
    Abstract: Snacks such as tortilla chips with melted nacho cheese toppings have become increasingly popular in recent years, and the dispensing of such snacks, as a single unit, in microwavable packages, for either home or vending stand use is desirable. A major problem with packaging cheese and chips in contact with one another in a single container, however, is that over time the chips, which are a low moisture content food, would draw moisture from the cheese, causing them to become soggy. The present invention remedies this problem by separating the cheese from the chips by containing it in an open grid integrated into the package top in such a way that when microwaved, the cheese will melt and be evenly distributed over the chips.

  • Patent number: 6486455
    Abstract: The present invention relates to a container for cooking food in a microwave oven. The container includes a tray having a bottom wall and a side wall that is attached to the bottom wall and extends upwardly from the bottom wall to define an interior cavity and a support means to provide support for a food product and elevate the food product with respect to the bottom wall. A continuous shielding layer is provided in the bottom wall and the side wall of the tray. The bottom wall and side wall of the tray along with the bottom of the food product define a free space under the food product that totally reflects microwave beams that pass through the food product back in the direction of the food product. The container of the invention reduces the formation of temperature gradients in the food product when it is heated and accelerates the microwave reheating of the food product. The container is particularly useful for reheating large blocks of frozen food.
