  • Patent number: 5183787
    Abstract: Disclosed are improved ceramic compositions which are useful in the formulation of microwave susceptors and to the susceptors fabricated therefrom for disposable packages for the microwave heating of food items. The compositions include certain metal salts as time/temperature profile moderators in addition to a novel microwave absorbing material and a binder. Certain metal salts can be used to dampen or lower the final temperatures reached upon microwave heating the ceramic compositions. Other metal salts can be used to increase or accelerate the final temperature reached upon microwave heating. The microwave absorbing materials comprise selected ceramics in both their native and amphoteric forms. Such useful ceramics are those with residual lattice charges or an unbalance of charge in the fundamental framework or layers such as vermiculite, bentonite, hectorite, zeolites, selected micas including Glauconite, phlogopite and Biotite and mixtures thereof.

  • Patent number: 4861614
    Abstract: Disclosed are shelf stable food compositions comprising infused, dry, oatmeal flakes useful for the preparation of instant oatmeal. The instant oatmeal is, however, characterized by the oatmeal flake size, appearance, texture and taste of traditional oatmeal. The present oatmeal can be prepared by the consumer by simple addition of hot water and a 30 second steeping. Also disclosed are methods of preparing the improved dry oatmeal. The methods involve infusion of oatmeal flakes or preferably steamed oatmeal groats prior to flaking of between 1% to 35% of the oatmeal flakes of low molecular weight solutes such as sugars and polyhydric alcohols. The infused oatmeal flakes are then dried to water activities ranging from 0.17 to 0.7.

  • Patent number: 4661359
    Abstract: Disclosed are edible film coating compositions of low moisture permeability and their methods of preparation. The compositions comprise cross-linked, refined shellac and hydroxypropyl cellulose (HPC) in a weight ratio of 1:0.001 to 1:2. Highly preferred compositions additionally comprise mono- or di-carboxylic acid adducts such as adipic, succinic, lauric, or stearic acids in a weight ratio of acid to combined weight of shellac and cellulose of 1:33 to 1:10. In the preferred method of preparing, the shellac is cross-linked in a dry, molten mixture with the HPC by heating at 130.degree. to 175.degree. C. for 2 to 15 minutes. The coating compound while molten is dissolved in a food grade solvent, applied to a substrate, and dried. The coating compositions are particularly useful as a moisture barrier in composite food articles having phases in contact which differ substantially in water activity. Effective films range from 0.1 to 5 mils in thickness.
