摘要： A packaging system is disclosed which includes a susceptor that heats when exposed to microwave radiation, and which has a selective responsiveness to microwave radiation. The susceptor surface has a plurality of regions, where at least one region has an altered responsiveness to microwave radiation which is achieved by disruptions in the susceptor surface. A method for making regions of a susceptor selectively responsive to microwave heating by disrupting the continuity of the metallized film of the susceptor is also disclosed.

摘要： A method and apparatus for measuring strong microwave electric field strengths is disclosed. The apparatus includes a first active temperature probe in cooperation with susceptor means for measuring a temperature indicative of the heating effects of microwave radiation at a test location, and an ambient temperature probe for measuring ambient temperature. The temperature differential between the two probes is used by calibration means for determining electric field strength at the test location. The method includes the steps of heating a susceptor means with microwave radiation, and measuring a temperature indicative of the heating effects of microwave radiation at the test location. Ambient temperature is measured, and the temperature differential used to determine the magnitude of the electric field strength.

摘要： There is provided an improved process for the biosynthetic production of indigo, the improvement comprising removing unwanted by-products such as isatin or indirubin from the broth in which such indigo is produced. Isatin can be removed by enzymatic activity using an isatin-removing enzyme such as an isatin hydrolase, or by other techniques such as process parameters (elevated temperature, pH), or by contacting the broth containing the isatin with appropriate adsorption compounds/compositions such as carbon or appropriate resins. Since isatin is the precursor of indirubin, the indirubin levels are decreased as a result of isatin removal.

摘要： An apparatus for heating a food item in a microwave oven is disclosed which has heater regions in combination with a reflective lattice structure. The combination of the reflective lattice structure and heater regions provides a food heating device which substantially maintains its reflectance, absorbance and transmittance during microwave heating. Substantial uniformity of heating is also achieved. The reflectance, transmittance and absorbance of the food heating device can be adjusted by changing the relative configuration and construction of the lattice structure and the heater regions.

摘要： A food container for use in a microwave oven is disclosed. The container contains a plurality of food substances, and employs a metal shield to shield at least one of the food substances from microwave radiation. Arcing and other problems associated with the use of metal shielding are avoided by proper selection of the geometry of the metal shield. The metal shield is preferably looped in a manner which provides some electrical inductance, and the ends of the metal shield are overlapped and separated by a dielectric material to provide some electrical capacitance. The geometry of the shield is selected so that the inductance and the capacitance in effect form a "tuned circuit" which minimizes problems associated with resonance and which eliminates arcing.

摘要： A food package for a microwave oven is disclosed which has a grid in combination with a susceptor means. The combination of the grid and susceptor means provides a heater element which substantially maintains its reflectance, absorbance and transmittance during microwave heating. Substantial uniformity of heating is also achieved. The reflectance, transmittance and absorbance can be adjusted by changing certain design factors, including hole size, susceptor impedance, grid geometry, spacing between the grid and susceptor, and the spacing between adjacent holes.

摘要： A package for heating food in a microwave oven is disclosed. The package includes metal shielding or other metal components which cause a gain in electric field strength which is greater than 3. The present invention also involves low load microwave environments where the electric field strength is greater than 10 volts per centimeter. A rigid, dimensionally stable dielectric support is provided in close proximity to a conductive sheet, being spaced less than 0.5 inch from the conductive sheet. The dielectric support is composed of material selected to avoid failure of the dielectric support in high electrical fields which may exist near the conductive sheet during microwave irradiation. The dielectric support material has a dielectric loss factor less than 0.005, and a failure temperature greater than 101.degree. C. The present invention relates to intrinsically nonarcing packages. A method for selecting packaging material for use in a shielded microwave container having a gain greater than 3 is also disclosed. A package material is selected having a combination of dielectric loss factor, heat capacity, density, and failure temperature, such that during microwave heating for a predetermined microwave heating time the failure temperature of the package material would not be exceeded.
