Abstract
Abstract Brown and serve products are produced by a microwave process in substantially less time than the current conventional production time. These products are baked directly in the sales carton which eliminates most handling and transfer. In addition, the shelf life of brown and serve rolls is increased by microwave baking in the sales carton and immediately overwrapping while hot with a shrink film overwrap. The process of microwave proofing of brown and serve rolls also reduces the overall processing time.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
80 words
A method of processing brown and serve rolls comprising the steps of: preparing a dough; forming the individual rolls; placing the rolls in sales cartons; proofing said rolls for about 7 to 12 minutes utilizing microwave energy having a frequency of 915 MHz and a flux density of about 11 to 34 watt hours per pound; and baking said rolls for about 4 to 6 minutes utilizing microwave energy having a frequency of 915 MHz at an effective flux density.
Claim 2
Independent Claim
80 words
A method of processing brown and serve rolls comprising the steps of: preparing a dough; forming the individual rolls; placing the rolls in sales cartons; proofing said rolls for about 7 to 12 minutes utilizing microwave energy having a frequency of 915 MHz and a flux density of about 11 to 34 watt hours per pound; and baking said rolls for about 4 to 6 minutes utilizing microwave energy having a frequency of 915 MHz at an effective flux density.
Claim 3
Dependent Claim
32 words
The method of claim 1, further including the step of: wrapping the baked rolls, while hot, with a shrink film and then passing the wrapped cartoned rolls through a heated shrink tunnel.
Claim 4
Independent Claim
79 words
A method of increasing shelf life of brown and serve rolls comprising the steps of: cartoning the dough formed rolls; proofing the rolls utilizing microwave energy having a frequency of 915 MHz and a flux density of about 11 to 34 watt hours per pound for an effective time; baking the rolls with microwave energy having a frequency of 915 MHz; wrapping the baked rolls while hot with a shrink film; and passing said rolls through a shrink tunnel.
Claim 5
Independent Claim
79 words
A method of increasing shelf life of brown and serve rolls comprising the steps of: cartoning the dough formed rolls; proofing the rolls utilizing microwave energy having a frequency of 915 MHz and a flux density of about 11 to 34 watt hours per pound for an effective time; baking the rolls with microwave energy having a frequency of 915 MHz; wrapping the baked rolls while hot with a shrink film; and passing said rolls through a shrink tunnel.
Claim 6
Dependent Claim
15 words
The method of claim 3, wherein the proofing time is about 7 to 12 minutes.
Claim 7
Dependent Claim
30 words
The method of claim 4, wherein the microwave baking energy is applied for about 4 to 6 minutes at flux densities between about 47.6 to 76.2 watt hours per pound.
Claim 8
Independent Claim
86 words
A method of decreasing the time required for processing brown and serve rolls and improving shelf life of said rolls, comprising: preparing a dough; forming individual rolls from said dough; placing the rolls in the retail carton; proofing and baking said rolls in the carton with microwave energy having a mixture of frequencies of 915 MHz and 2450 MHz at an effective flux density for an effective time; and promptly overwrapping the cartoned rolls while still hot with a heat shrinkable film in a heated tunnel.
Claim 9
Independent Claim
86 words
A method of decreasing the time required for processing brown and serve rolls and improving shelf life of said rolls, comprising: preparing a dough; forming individual rolls from said dough; placing the rolls in the retail carton; proofing and baking said rolls in the carton with microwave energy having a mixture of frequencies of 915 MHz and 2450 MHz at an effective flux density for an effective time; and promptly overwrapping the cartoned rolls while still hot with a heat shrinkable film in a heated tunnel.
