Abstract

This invention provides a reactive dough composition which undergoes chemical surface browning upon exposure to microwave energy. This reactive dough composition is preferably incorporated as a coating layer on frozen food products having a crust component, e.g., pies. The resulting food product can be heated or cooked in a microwave oven to give a cooked product which is comparable or superior in color and flavor to fresh products baked in a conventional oven. The reactive composition contains as the essential active ingredients a reducing sugar such as dextrose and an amino acid source such as a yeast extract.

Claims

1. A composite dough material for incorporation into a food product as a crust, said composite dough material comprising an unreactive substrate dough layer which does not brown upon exposure to microwave energy and said substrate dough layer having coated thereon a thin, uniform layer of a reactive dough composition which undergoes chemical surface browning reactions upon exposure to microwave energy, said reactive dough composition comprising a dough-base having added thereto a reducing sugar and an amino acid source the ratio of reducing sugar to amino acid source being sufficient to promote said chemical surface browning reaction when the composite is exposed to microwave energy for a desired period of time.

2. A food product having as one component thereof a crust formed from the composite dough material of claim 1.

4. The invention of claim 1, 2 or 3 wherein said reducing sugar is selected from the group consisting of dextrose, maltose, fructose and mixtures thereof.

5. The invention of claim 4 wherein said reducing sugar is dextrose.

6. The invention of claim 1, 2 or 3 wherein said amino acid source is an autolyzed yeast product.

7. The invention of claim 6 wherein said autolyzed yeast product is a yeast extract.

8. The invention of claim 7 wherein said yeast extract is present in said reactive dough composition in an amount of at least about 0.5% solids by weight.

9. The invention of claim 2 or 3 wherein said food product is a meat pie.

10. The invention of claim 2 or 3 wherein said food product is a fruit pie.

12. The invention of claim 1, 2 or 3 wherein said reactive dough composition comprises about 4 to 18% yeast extract, about 25 to 40% flour, about 20 to 40% shortening, about 20 to 40% water, and sufficient reducing sugar to provide a ratio of reducing sugar solids to yeast extract solids of from about 1:

1 to 1;

10.

3. A process for treating a food product having as a component thereof a crust, said process being effective to render the surface of said crust component brownable upon exposure to microwave energy and decrease the time and temperature necessary to brown the surface of said product in a conventional oven, said process comprising coating the surface of said crust component with a thin uniform layer of a reactive dough composition comprising a dough-base having added thereto, a reducing sugar and an amino acid source sufficient to promote a chemical surface browning reaction when the composite is exposed to microwave energy for a desired period of time.

11. The invention of claim 3 wherein the browning reaction is enhanced by placing said food product in a covered container and subjecting the container and food product to microwave energy.
