Abstract
The subject invention provides a bran composition comprising a bran component with a reduced level of inorganic arsenic, a grain product that comprises such bran composition and at least one other component and/or other ingredient, and food products that are made from such bran composition and/or such grain product. The subject invention also provides methods of detoxifying a bran and/or grain product.
Claims20
A method of reducing inorganic arsenic in a sample, the method comprising:
- 1) providing the sample, which contains at least 1 mg/kg of inorganic arsenic by weight;
- and
- 2) methylating the inorganic arsenic by treating the sample with a methylating enzyme, more than 90% of the inorganic arsenic present in the sample being converted into dimethylarsenate (DMA).
A method for treating a bran or grain product, the method comprising:
- mixing the bran or grain product with a buffer solution to create a slurry, the bran or grain product having at least about 1 mg/kg of inorganic arsenic by weight;
- adding a heat-stable methylating enzyme to the slurry to methylate the inorganic arsenic;
- and
- optionally, detecting the level and species of inorganic arsenic in the slurry.
A method for modifying a bran or grain product, the method comprising:
- mixing the bran or grain product with a buffer solution to create a slurry, the bran or grain product having at least about 1 mg/kg of inorganic arsenic by weight;
- adding a heat-stable methylating enzyme to the slurry to methylate the inorganic arsenic;
- and
- optionally, detecting the level and species of inorganic arsenic in the slurry.
