Abstract
A novel package assembly and method are disclosed whereby a food product having a moisture content of less than 5 weight percent is disposed in a sealed package in which a sealed packet of an aqueous solution is also disposed; so that upon exposure to microwave radiation, the solution in the sealed packet vaporizes, rupture the packet and is dispersed as steam throughout the sealed package, whereby the temperature of the low moisture food product is increased.
Claims15
A method of heating a low-moisture food product, having a moisture content of less than five weight percent, comprising the steps of:
- (a) providing a food product having a moisture content of less than five weight percent;
- (b) providing an aqueous solution disposed in a sealed packet which is at least partially transparent to microwave radiation;
- (c) disposing the low-moisture food product and the aqueous solution-containing sealed packet in a sealed package, which package is transparent to microwave radiation;
- (d) irradiating the sealed package with microwave radiation, causing the aqueous liquid in the sealed packet to volatilize and rupture said packet after less than thirty seconds of exposure to microwave radiation;
- and
- (e) dispersing the volatilized liquid as steam throughout the sealed package so as to increase the temperature of the food product.
A method of heating a food product having less than two weight percent moisture, comprising the steps of:
- (a) providing a food product having a moisture content of less than two weight percent;
- (b) providing an aqueous electrolytic solution in an amount such that the ratio of the food product of step (a) to the aqueous electrolytic solution ranges from 1:0.005 to 1:0.1, the solution disposed in a sealed packet which is at least partially transparent to microwave radiation;
- (c) disposing the low-moisture food product and the aqueous solution-containing sealed packet in a sealed package, which package is transparent to microwave radiation;
- (d) irradiating the sealed package with microwave radiation, causing the aqueous solution in the sealed packet to volatilize and rupture said packet after less than thirty seconds of exposure to microwave radiation;
- and
- (e) dispersing the volatilized solution as steam throughout the sealed package so as to increase the temperature of the food product to between 43.degree. C. (110.degree. F.) and 135.degree. C. (275.degree. F.).
A method of heating a salty snack food having less than two weight percent moisture, comprising the steps of:
- (a) providing a salty snack food having a moisture content of less than two weight percent;
- (b) providing an aqueous electrolytic solution in an amount such that the ratio of the salty snack food of step (a) to the aqueous electrolytic solution ranges from 1:0.01 to 1:0.09, the solution disposed in a sealed packet which is at least partially transparent to microwave radiation;
- (c) disposing the low-moisture food product and the aqueous solution-containing sealed packet in a sealed package, which package is transparent to microwave radiation;
- (d) irradiating the sealed package with microwave radiation, causing the aqueous solution in the sealed packet to volatilize and rupture said packet after less than thirty seconds of exposure to microwave radiation;
- and
- (e) dispersing the volatilized solution as steam throughout the sealed package so as to increase the temperature of the food product to between 71.degree. C. (160.degree. F.) and 88.degree. C. (190.degree. F.).
