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 2 wherein the fumigation chamber comprises about 15,000 kg to about 25,000 kg psyllium husk.

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

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

5 . 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.

6 . The method of claim 1 wherein the shipping container comprises from about 45% to about 77% empty space by volume.

7 . 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.

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

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

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

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

12 . 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.

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

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