Abstract

The present document describes a process for the sterilization and/or pasteurization of sap without denaturing polyphenols and other ingredients present therein, and a sap product prepared from the processes.

Claims

1. In a method of sterilization and/or pasteurization of sap or sap concentrate;

the improvement characterized in the step of;

a) sterilization treatment of said sap or sap concentrate for a time sufficient to substantially inhibit microbial growth in said sap or sap concentrate with minimal taste alteration, or

pasteurization treatment of said sap or sap concentrate for a time sufficient to pasteurize, wherein said pasteurization treatment is at least one of a heat pasteurization treatment, a High Temperature Short Time (HTST) treatment, a thermization treatment, a centrifugation treatment, a UV treatment, and combinations thereof, or

micro-filtration of said sap or sap concentrate with a micro-filter of pore size between about 0.1 μ

m to about 1 μ

m,

or combinations thereof,

prior to transporting, storing and transporting, transporting and storing, performing a sterilization treatment, or combinations thereof, of said sap or sap concentrate.

2. The method of claim 1, further comprising step b) after step a):

b) sterilization treatment of said sap or sap concentrate for a time sufficient to substantially inhibit microbial growth in said sap or sap concentrate with minimal taste alteration or

desiccation treatment of said sap or sap concentrate for a time sufficient to substantially eliminate water in said sap or sap concentrate.

3. The method of claim 2, further comprising the step a′

) before or after step b);

a′

) storing said sap or sap concentrate.

4. The method of claim 2, further comprising the step a″

) before or after step b);

a″

) transporting said sap or sap concentrate.

5. The method of claim 3, further comprising the step a′

″

) before or after steps a′

);

a′

″

) transporting said sap or sap concentrate.

6. The method of claim 1, wherein said heat pasteurization treatment is by heating from about 50°

C. to at about 100°

C. for a time sufficient to pasteurize, and wherein said time sufficient to pasteurize is from about 10 seconds to about 150 minutes.

7. The method of claim 6, wherein said heat pasteurization treatment is a High Temperature Short Time (HTST) treatment from about 70°

C. to 100°

C. for about 15 seconds to about 30 seconds.

8. The method of claim 6, wherein said pasteurization treatment is a thermization treatment from about 63°

C. to about 65°

C., for about 15 to 25 seconds.

9. The method of claim 6, wherein said centrifugation treatment is a bactofugation treatment.

10. The method of claim 2, wherein said desiccation is at least one of a lyophilization, a spray drying, or combinations thereof.

11. The method of claim 313, wherein said storing is at least one of freezing said sap or sap concentrate, refrigerating said sap or sap concentrate, or combinations thereof.

12. The method of claim 1, wherein said sterilization treatment is at least one of a heat sterilization treatment, a dry heat sterilization treatment, a tyndallisation treatment, an upperization treatment, a high pressure processing (HPP) treatment, canning, a ultrasound treatment, a CO₂ treatment, a UV treatment, a gamma ray treatment, a X-ray treatment, a pulsed light sterilization treatment, a microwave sterilization treatment, a pulsed electric field sterilization, a pulsed magnetic field sterilization, an ozone sterilization treatment, a microfiltration, and combinations thereof.

13. The method of claim 12, wherein said heat sterilization treatment is from about 100°

C. to about 160°

C. for about 1 seconds to about 60 seconds, or from about 130°

C. to about 150°

C. for about 2 seconds to about 8 seconds, or from about 115°

C. to about 137°

C. for about 15 minutes to about 130 minutes, or from about 137°

C. to about 140°

C. for about 2 seconds to about 10 seconds.

14. The method of claim 12, wherein said high pressure processing (HPP) treatment is from about 999,74 kPa to about 999 739,808 kPa for about 4 minutes to about 30 minutes, or from about 599 843,885 kPa for about 15 minutes, or from about 599 843,885 kPa for about 6 minutes, or from about 599 843,885 kPa for about 4 minutes.

15. The method of claim 12, wherein said tyndallisation treatment is from about 70°

C. to about 100°

C., for about 30 mins to about 120 mins, for 3 consecutive days.

16. The method of claim 12, wherein said upperization treatment is from about 140°

C. to about 150°

C., for about 2 secs to about 3 seconds, followed by homogenization of said sap or sap concentrate.

17. The method of claim 12, wherein said UV treatment is from about 2000 μ

W s/cm² to about 9500 μ

W s/cm² of ultraviolet light for a time sufficient to effect sterilization, or from about 10 kGy to about 100 kGy, or from about 10 kGy or less, or from 5 kGy or less.

18. The method of claim 12, wherein said gamma ray treatment is from about 10 kGy to about 100 kGy, or from about 1 kGy to about 15 kGy, or from about 1 kGy to about 10 kGy.

19. The method of claim 12, wherein said X-ray treatment is from about 10 kGy to about 50 kGy or from about 1 kGy to about 15 kGy, or from about 1 kGy to about 10 kGy.

20. The method of claim 1, wherein said sap or sap concentrate is produced by a plant chosen from an Acer tree, a birch, a pine, a hickory, a poplar, a coconut from a coconut palm tree (Cocos nucifera), and an agave.
