Abstract

A method for fumigating psyllium husk. The method comprises filling a fumigation chamber with psyllium husk chamber is at least 35% filled with bags of psyllium husk, fumigating the psyllium husk with at least 40 g/m3 of methyl bromide for at least 24 hours, and degassing the chamber for at least 6 hours to form fumigated psyllium husk. The fumigated psyllium husk comprises less than 50 ppm inorganic bromide residue and the fumigated psyllium husk does not comprise an insect infestation or a khapra beetle infestation.

First claim

What is claimed is:

1. A method for providing fumigated and sanitized psyllium husk comprising:
a. first separating psyllium husk from psyllium seed;
b. filling a fumigation chamber with the psyllium husk such that the chamber comprises about 35% to about 50% psyllium husk by volume;
c. fumigating the psyllium husk with at least about 40 g/m 3 of methyl bromide for at least about 24 hours;
d. degassing the fumigation chamber for at least about 6 hours to form fumigated psyllium husk;
e. steam sanitizing the psyllium husk;

wherein the fumigated psyllium husk comprises less than about 50 ppm inorganic bromide residue.

2. The method of claim 1 wherein the fumigation chamber comprises about 7000 kg to about 12,000 kg psyllium husk.

3. The method of claim 1 wherein the fumigation chamber comprises about 15,000 kg to about 25,000 kg psyllium husk.

4. The method of claim 1 wherein the fumigation is performed at a temperature that is less than or equal to about 40° C.

5. The method of claim 1 wherein the fumigation is performed at a temperature that is less than or equal to about 35° C.

6. The method of claim 1 further comprising removing the fumigated psyllium husk from the fumigation chamber; fumigating a shipping container and putting the fumigated psyllium husk in the shipping container.

7. The method of claim 5 wherein the shipping container comprises from about 45% to about 77% empty space by volume.

8. A method for providing fumigated and sanitized psyllium husk comprising:
a. first separating psyllium husk from psyllium seed;
b. filling a fumigation chamber with the psyllium husk such that the chamber comprises about 35% to about 50% psyllium husk by volume;
c. fumigating the psyllium husk with about 30 g/m 3 to about 70 g/m 3 of methyl bromide for about 12 hours to about 36 hours;
d. degassing the fumigation chamber for at least about 6 hours to form fumigated psyllium husk;
e. steam sanitizing the psyllium husk;

wherein the fumigated psyllium husk comprises less than about 50 ppm inorganic bromide residue.

9. The method of claim 7 wherein the fumigation chamber comprises about 7000 kg to about 12,000 kg psyllium husk.

10. The method of claim 7 wherein the fumigation chamber comprises about 15,000 kg to about 25,000 kg psyllium husk.

11. The method of claim 7 wherein the fumigation is performed at a temperature that is less than or equal to about 40° C.

12. The method of claim 7 wherein the fumigation is performed at a temperature that is less than or equal to about 35° C.

13. The method of claim 7 further comprising removing the fumigated psyllium husk from the fumigation chamber; fumigating a shipping container and putting the fumigated psyllium husk in the shipping container.

14. The method of claim 12 wherein the shipping container comprises from about 45% to about 77% empty space by volume.

15. The method of claim 7 wherein the fumigation is performed with from about 35 to about 50 g/m 3 of methyl bromide.
