Abstract

A method for applying a powdered antimycotic composition to a foodstuff, the method including mixing a powdered antimycotic composition in an air stream, applying a uniform coating of antimycotic composition to each surface of a bulk foodstuff and slicing the foodstuff into a plurality of slices having the desired antimycotic surface concentration on each surface thereof.

Claims

1. A method for automatically applying an antimycotic composition to sliced foodstuff:

providing a bulk foodstuff having an exterior surface and of a size capable of being fed to a food slicing device;

providing a powdered antimycotic composition at a predetermined flowrate;

mixing the antimycotic composition with a stream of pressurized air supplied at a pressure sufficient to evenly distribute the antimycotic composition within the stream;

applying an effective amount of antimycotic composition to the exterior surface of the bulk foodstuff by contacting the mixed antimycotic/air stream with the exterior surface of the foodstuff; and

slicing the bulk foodstuff into a plurality of slices.

2. The method of claim 1, wherein the bulk food stuff is a cheese log.

3. The method of claim 1, wherein the antimycotic composition comprises natamycin.

4. The method of claim 1, wherein the mixing step further comprises:

filtering the pressurized air; and

metering the antimycotic composition at a predetermined flowrate to the stream of pressurized air.

5. The method of claim 1, wherein the applying step further comprises:

spraying the exterior surface of the bulk foodstuff with the mixed antimycotic/air stream to provide a substantially uniform layer of powdered antimycotic composition on each surface.

6. The method of claim 1, wherein the applying step further comprises:

substantially equally dividing the mixed antimycotic/air stream into a plurality of mixed antimycotic/air streams; and

dispensing the antimycotic composition to the exterior surface of the bulk foodstuff using a plurality of nozzles spaced apart from the bulk foodstuff.

7. The method of claim 1, wherein the applying step further comprises:

contacting the mixed antimycotic/air stream with the exterior surface of the foodstuff while simultaneous conveying the bulk foodstuff from a subsequent bulk cutting operation to the food slicing device.

8. A method for automatically applying an antimycotic composition to a sliced cheese product:

providing a cheese log having an exterior surface, the cheese log being of a size capable of being fed to a food slicing or cutting device;

metering a powdered antimycotic composition comprising natamycin at a given flow rate to a stream of compressed air and uniformly dispersing the antimycotic composition therein;

dividing the mixed antimycotic/air stream into a plurality of mixed antimycotic/air streams, each having substantially the same flowrate;

spraying the exterior surface of the cheese log with the plurality of mixed antimycotic/air streams while the cheese log is simultaneously conveyed from a first location to the slicing or cutting device to provide a layer of antimycotic composition of substantially uniform thickness on the exterior surface of the cheese log; and

cutting the cheese log into a plurality of cheese portions, each cheese portion having at least one cut surface, wherein an effective amount of the powdered antimycotic composition from the layer of antimycotic composition on the exterior surface of the cheese log is transferred to the least one cut surface of each cheese portion.

9. The method of claim 8, wherein the providing step includes providing a plurality of cheese logs, each cheese log having an exterior surface and being of a size capable of being fed to the food slicing or cutting device.

10. The method of claim 8, wherein the metering step includes mixing the powdered antimycotic composition with compressed air having a pressure of about 80 to about 100 psi.

11. The method of claim 8, wherein the dividing step includes supplying the mixed antimycotic/air stream into a mixing manifold and then supplying the mixed antimycotic/air stream to a plurality of nozzles.

12. The method of claim 11, further comprising recirculating any antimycotic composition not applied to the exterior surface of the cheese log back to the mixing manifold.

13. The method of claim 8, further comprising determining the thickness of the layer of antimycotic composition required on the exterior surface of the cheese log in order distribute the effective amount of antimycotic composition on the at least one cut surface of each of the cheese portions.

14. In a food production operation where a plurality of bulk food products are conveyed from a first processing operation to a subsequent slicing operation, a method for applying an effective amount of a dry natamycin composition to each slice of a bulk food product, the method comprising:

dispersing an amount of the dry natamycin composition at a given flow rate to a stream of high pressure air, wherein the air is supplied at a pressure sufficient to evenly distribute the dry natamycin in the air stream;

contacting each exterior surface of the bulk food product with the mixed dry natamycin/air stream while simultaneously conveying the bulk food product from the first processing operation to the slicing operation; and

slicing the bulk food product into a plurality of slices, each slice having at least one cut surface, wherein the effective amount of the powdered natamycin composition from the bulk food product is transferred to the least one cut surface of the bulk food product.

15. The method of claim 14, further comprising contacting each exterior surface of another one of the plurality of the bulk food products with the mixed dry natamycin/air stream while simultaneously conveying the bulk food product from the first processing operation to the slicing operation.
