A method for forming a food package product is disclosed. The food package product includes layers and patches of adhesive strategically placed on packaging stock that prevents leakage of liquid products. In an exemplary embodiment, the food package product is microwavable popcorn.

Frozen desserts contained in a microwave active packaging are disclosed. In some embodiments, the microwave active packaging includes a microwave active layer configured to selectively heat the contents of the microwave active packaging. The contents may include a first layer of frozen food, and one or more additional topping layers. When placed into a microwave, the microwave active layer causes the one or more additional topping layers to heat, while the first layer is maintained at or below a freezing temperature. Other embodiments may be described and/or claimed.

A beverage preparation package including a container defining a multiplicity of openings, and a beverage preparation composition positioned in the container. The beverage preparation composition includes a microwave susceptor and a beverage precursor. In some cases, the beverage preparation composition includes a particulate beverage precursor and a particulate microwave susceptor. The particulate beverage precursor typically includes a plant material, such as coffee beans, tea leaves, herbs, or the like. Preparing a beverage includes contacting water with a beverage preparation package including a beverage preparation composition and water, irradiating the water with microwave radiation to vaporize at least a portion of the water, thereby imparting a flavor from the beverage preparation composition to the water to yield the beverage. The beverage preparation composition can be separated from the beverage.

A device for microwave heating with inversion has a base and a cover defining a heating chamber. Both the base and the cover include a susceptor heatable by microwave energy and the cover includes an aperture to vent steam. With a food product in the heating chamber, the device is placed in a microwave oven resting on the base. During an initial heating period, the lower surface of the food product is browned or crisped due to conduction and steam escapes from the heating chamber via the aperture. After the initial heating period, the device in inverted and the food product comes into contact with the cover. The device is placed in the microwave oven resting on the cover during a secondary heating period in which the food product is heated further, and the upper surface of the food product is browned or crisped due to conduction.

A package containing nuts and suitable for microwave heating is described herein. The package is configured to heat the nuts and provide an aroma reminiscent of traditional, freshly-roasted nuts. The freshly-roasted nut attributes include an aroma, temperature, texture and taste, which are reproduced with the microwave package. The package preferably, though not necessarily, incorporates one or more susceptors in order to provide additional heating, such as conductive heating, to the nuts. The package also preferably includes a sufficient headspace to allow for the aromas to develop.

A container structure for sealing and keeping food fresh, which can be repacked after unpacking. The container structure has a container body and a covering film; the container body has a housing chamber, a first abutting face, a concave groove portion, a second abutting face and a preset break line; the covering film can seal the housing chamber and bond with the first and second abutting face, specifically, it is bonded to the first abutting face through the micro sealing portion, so that the bonding between the covering film and the first abutting face is weaker than the bonding between the second abutting face; To open the covering film, the user needs to apply a force upon the external edge of the top end of the container body, to break the preset break line, and to separate the covering film from the first abutting face, so as to form a separated and independent frame.

A device for and method of microwave heating with inversion. The device includes a base and a cover defining a heating chamber, with both of the base and cover including a susceptor which will be heated by microwave energy. The cover includes one or more apertures to vent steam from the heating chamber. In operation, the device includes a food product in the heating chamber. The device is placed in the microwave oven resting on the base. The microwave oven is operated for an initial heating period. During this time the food product is heated, and the lower surface of the food product is browned or crisped due to conduction. Also during this time, steam is escaping the heating chamber via the aperture. After the initial heating period the device in inverted and the food product comes into contact with the cover. The device is placed in the microwave oven resting on the cover. The microwave oven is operated for a secondary heating period. During this time the food product is heated further, and the upper surface of the food product is browned or crisped due to conduction.

A package for combined steam and microwave heating of food, wherein the package may include microwave energy interactive materials (MEIMs) configured for providing rapid, simultaneous microwave and steam cooking in a domestic microwave oven. The MEIMs may be configured for controlling the heating pattern within the package and to control volumetric heating of food in the package. The MEIMs may include one or more of a susceptor, shield, and/or resonating patch antenna. The package may be paper-based, or it may be manufactured of any other suitable material. One or more of the different sections of the package may comprise separate chambers respectively for the steam source and the food to be steamed, so that the steam source and the food to be steamed are separated from one another during manufacturing, storage, and cooking.

The present invention relates to a vessel having an area for holding at least one food item for being heated in a solid state microwave oven. Additionally, disclosed is a method for heating a food item in a solid state microwave oven. Particularly, the vessel comprises a tray having an area for holding at least one food item and a susceptor wherein there is a thermal insulation between the susceptor and the food item. The tray may include two- or multi-compartment configurations wherein the susceptor only spans at least along a portion of one compartment to heat various food item simultaneously within a solid state microwave oven.

Processes and systems that enhance the heating of packaged foodstuffs and other items in various microwave heating systems are described herein. The foodstuffs may be contained in a package including one or more energy control elements that interact with microwave energy in order to alter the effect that microwave energy has on the foodstuff. These energy control elements can enhance or inhibit microwave energy and a single package may include one or more energy control elements. In some cases, the energy control element may respond differently to different types of microwave energy. As a result, some packages described herein may exhibit different absorption or reflectance characteristics when exposed to microwave energy while being pasteurized or sterilized in a larger-scale microwave heating system than when the package is reheated in an at-home microwave oven prior to consumption or use.
