Abstract

A system and method for the continuous production of brown butter involves concentrating butter while retaining solids non-fat in the butter, and continuously transferring and heating the concentrated butter to cause the solids non-fat in the butter to react in a maillard reaction to form a brown butter product. The system may use one or more of a heating vessel, an evaporator and a reaction vessel to form the brown butter in the continuous process. A brown butter product derived from butter includes reacted solids non-fat particulates from a maillard reaction suspended by nascent fat crystals nucleated about the reacted solids non-fat particulates and by large fat crystal structures joined to the nascent fat crystals.

First claim

What is claimed is:

1. A method for the continuous production of a brown butter product, comprising:
heating a starting composition comprised of butter containing a starting moisture content in a first environment to cause a portion of the moisture to vaporize, thereby forming a moisture vapor and a concentrating butter composition, the concentrating butter composition having a reduced moisture content relative to the starting moisture content;
continuously transferring the concentrating butter composition and the moisture vapor to a second environment and removing the moisture vapor from the second environment to form a concentrated butter composition such that a moisture variation within the concentrated butter composition ranges up to about 3 percent before exiting the second environment; and
continuously transferring the concentrated butter composition to a third environment and heating the concentrated butter composition to cause a Maillard reaction in the concentrated butter composition to thereby form the brown butter product,
wherein the brown butter product is formed continuously in the third environment, and
wherein the brown butter product includes a moisture content of about 1 to about 6 percent.

2. The method of claim 1 , wherein at least one of the first or second environments is under vacuum pressure.

3. The method of claim 1 , wherein the first environment and the second environment are coupled by a vapor dome configured to receive the concentrating composition and the moisture vapor from the first environment and to enable the moisture vapor to rise above and separate from the concentrating composition.

4. The method of claim 3 , wherein the first environment is configured as a heat exchanger.

5. The method of claim 3 , wherein the second environment is a vessel configured to enable the concentrated composition to flow by gravity and to vent the moisture vapor.

6. The method of claim 5 , wherein the second environment is coupled to a vacuum pump.

7. The method of claim 1 , wherein the third environment comprises a scraped surface heat exchanger.

8. The method of claim 1 , further comprising suspending reacted solids non-fat particulates in the brown butter product.

9. The method of claim 8 , wherein the reacted solids non-fat particulates are suspended by cooling the brown butter product to about 50° F. to about 100° F.

10. The method of claim 8 , wherein the reacted solids non-fat particulates are suspended by agitating the brown butter product while cooling.

11. The method of claim 1 , wherein a moisture content of the concentrated composition is about the same as the brown butter product.

12. The method of claim 1 , wherein the brown butter product is derived solely from butter.

13. The method of claim 1 , wherein prior to concentrating, the starting composition includes from about 81 to about 85 percent total solids, and wherein the brown butter product includes from about 94 to about 99 percent total solids.

14. The method of claim 1 , wherein the brown butter product includes from about 94 to about 99 percent total solids.

15. The method of claim 1 , wherein fat, protein and sugar in the starting composition is the same as the concentrated composition.

16. A method for the continuous production of a brown butter product, comprising:
heating a concentrated butter composition in a heating environment to a reaction temperature to cause a Maillard reaction in the concentrated butter composition to form a brown butter product, wherein:
the concentrated butter composition includes a reduced moisture content relative to butter,
a particle size of reacted solid non-fat particulates from the Maillard reaction ranges from about 41 μm to about 73 μm, and
the brown butter product is formed continuously in the heating environment;

transferring the brown butter product from the heating environment to a first cooling environment and cooling from about the reaction temperature to about 100° F., wherein:
cooling the brown butter product in the first cooling environment causes nascent fat crystals to nucleate on the reacted solids non-fat particulates; and

transferring the brown butter product from the first cooling environment to a second cooling environment and cooling to between about 80° F. and about 50° F., wherein:
cooling the brown butter product in the second cooling environment causes fat crystals larger than the nascent fat crystals to adhere to the nascent fat crystals and suspend the reacted solids non-fat particulates in the brown butter product, and
wherein the second cooling environment gradually cools the brown butter product relative to the first cooling environment.

17. The method of claim 16 , wherein the brown butter product is derived solely from butter.

18. The method of claim 16 , wherein the brown butter product includes from about 94 to about 99 percent total solids.
