Abstract
Abstract The defrosting and subsequent heating, cooking and/or baking of a frozen convenience food, in a microwave oven, is enhanced by surface-defrosting-wetting the surface of said frozen food with water to cause a positive surface-to-core differential in microwave lossiness in said food prior to exposing said surface-defrosted food to microwave radiation. Described is the step of blotting and/or draining off excess water after wetting and prior said exposure to microwave radiation. Described is adding replacement frying oil to microwave-heated fried convenience food. Also, described is the combination of the methods of this invention with the methods and apparatus described in U.S. Pat. Nos. 3,985,990 and 3,985,991 and in copending application U.S. Ser. No. 129,360, filed Mar. 11, 1980. The harvest-freezing for later defrosting of certain foods is described.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
134 words
In a method of defrosting and heating in a microwave oven a frozen food, the steps which include: surface-defrosting-wetting said frozen food with water to create a positive surface-to-core differential in microwave lossiness in said food, enclosing said food in an inner, microwave-permeable member which contains a plurality of openings of sufficient size to permit the passage across said member of liquid-and-oil by-products of said food when evolved from said food due to exposing said food to microwave energy and of sufficient size to limit the passage across said member of said liquid-and-oil when said liquid-and-oil is not exposed to microwave energy, containing said food and said inner member in an outer microwave-permeable container fabricated to contain water and oil therein, and exposing said food to microwave radiation until said food defrosts and heats.
Claim 2
Dependent Claim
134 words
In a method of defrosting and heating in a microwave oven a frozen food, the steps which include: surface-defrosting-wetting said frozen food with water to create a positive surface-to-core differential in microwave lossiness in said food, enclosing said food in an inner, microwave-permeable member which contains a plurality of openings of sufficient size to permit the passage across said member of liquid-and-oil by-products of said food when evolved from said food due to exposing said food to microwave energy and of sufficient size to limit the passage across said member of said liquid-and-oil when said liquid-and-oil is not exposed to microwave energy, containing said food and said inner member in an outer microwave-permeable container fabricated to contain water and oil therein, and exposing said food to microwave radiation until said food defrosts and heats.
Claim 3
Dependent Claim
34 words
In a method of defrosting and heating in a microwave oven a frozen food, according to claim 1, the added step of: placing a water-and-oil-absorptive material between said inner member and said outer container.
Claim 4
Dependent Claim
29 words
In a method of defrosting and heating in a microwave oven a frozen food, according to claim 1, which includes: where said member is a high-temperature plastic perforated film.
Claim 5
Dependent Claim
68 words
In a method of defrosting and heating in a microwave oven a frozen food, according to claim 1, which includes: where said frozen food is a deep-fat-fried-and-then-frozen convenience food and where, after said exposure to microwave radiation, adding a predetermined amount of frying oil to the top surface of said fried food to replace the frying oil lost to said top surface during said exposure to microwave radiation.
