Abstract

An enzyme mixture for tenderizing raw beef comprising between about 98.7% and about 99.7% bromelin, between about 0.02% and about 0.08% ficin and between about 0.01% and about 0.05% papain. A method of tenderizing raw beef to produce a product that can be cooked by the consumer using the same methods as preparing naturally tender beef, and that results in a post-consumer preparation product that is consistently tender. The method comprises providing a suitable cut of raw beef and treating the raw beef with an enzyme mixture comprising between about 98.7% and about 99.7% bromelin, between about 0.02% and about 0.08% ficin and between about 0.01% and about 0.05% papain.

Claims

1. An enzyme mixture for tenderizing raw beef, comprising between about 98.7% and about 99.7% bromelin, between about 0.02% and about 0.08% ficin, and between about 0.01% and about 0.05% papain.

2. The enzyme mixture of claim 1, comprising between about 99% and about 99.4% bromelin, between about 0.04% and about 0.06% ficin and between about 0.02% and about 0.04% papain.

3. The enzyme mixture of claim 1, comprising 98.2% bromelin, 0.05% ficin and 0.03% papain.

4. A composition for tenderizing raw beef, comprising the enzyme mixture of claim 1 and a carrier.

5. The composition of claim 4, where the enzyme mixture is present in an amount of between about 0.5% and about 6% of the composition.

6. The composition of claim 4, where the enzyme mixture is present in an amount of between about 0.7% and about 2% of the composition.

7. The composition of claim 4, where the enzyme mixture is present in an amount of about 1% of the composition.

8. The composition of claim 4, where the carrier is NaCl.

9. The composition of claim 4, where the carrier is present in an amount of between about 25% and about 99%.

10. The composition of claim 4, where the carrier is present in an amount of between about 50% and about 99%.

11. The composition of claim 4, where the carrier is present in an amount of about 98.5%.

12. The composition of claim 4, further comprising a processing aid.

13. The composition of claim 12, where the processing aid is soybean oil.

14. The composition of claim 4, where the processing aid is present in an amount of between about 0.1% and about 2%.

15. The composition of claim 12, where the processing aid is present in an amount of between about 0.3% and about 1%.

16. The composition of claim 12, where the processing aid is present in an amount of about 0.5%.

17. The composition of claim 12, comprising about 98.4% carrier, about 1.1% enzyme mixture and about 0.5% processing aid.

18. A method of tenderizing raw beef, the method comprising:

a) providing a suitable cut of raw beef; and

b) treating the raw beef with an enzyme mixture according to claim 1.

19. The method of claim 18, where the raw beef provided is partially or completely skinned, boned or both.

20. The method of claim 18, where the raw beef provided has waste products or excess fat removed.

21. The method of claim 18, where the raw beef provided is an amount between about 0.1 kg to about 10,000 kg.

22. The method of claim 18, where the raw beef provided is an amount between about 100 kg and 6000 kg.

23. The method of claim 18, where treating the raw beef comprises injecting the raw beef with a solution containing the enzyme mixture.

24. The method of claim 18, where treating the raw beef comprises injecting the raw beef with a solution comprising a composition that comprises the enzyme mixture.

25. The method of claim 24, where the composition additionally comprises a carrier.

26. The method of claim 24, where the composition additionally comprises a processing aid.

27. The method of claim 24, where the ratio of weight of the composition injected to the total weight of the beef being injected with the composition is between about 1:

200 and about 1;

1500.

28. The method of claim 24, where the ratio of weight of the composition injected to the total weight of the beef being injected with the composition is between about 1:

450 and about 1;

650.

29. The method of claim 24, where the solution comprises the composition, ice, NaCl and potable water.

30. The method of claim 24, where the solution injected is between about 6% and about 20% of the weight of the beef being injected.

31. The method of claim 24, where the solution injected is about 15% of the weight of the beef being injected.

32. The method of claim 18, further comprising adding to the raw beef one or more than one substance selected from the group consisting of flavoring, NaCl, moisture enhancing agents, preservatives, and potable water.

33. The method of claim 18, further comprising tumbling the treated raw beef at a pressure and rotation speed selected to more evenly distribute the enzyme mixture or composition throughout the treated beef.

34. The method of claim 33, where the pressure is a near vacuum.

35. The method of claim 33, where the rotation speed is about between about 10 to about 15 revolutions per minute.

36. The method of claim 18, further comprising exposing the treated raw beef to a relative vacuum a closed container.

37. The method of claim 36, where the closed container is a polymer bag.

38. The method of claim 36, where the relative vacuum is about −

1.5 bar.

39. The method of claim 18, further comprising packaging the treated raw beef in a commercial package.

40. The method of claim 18, further comprising distributing the treated raw beef to an intermediate wholesale or retail establishment.
