Methods for detoxifying bran and products obtained therefrom
View Patent ↗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.
1 . A detoxified bran composition comprising a detoxified bran component with a more than 90% reduction in inorganic arsenic compared to an undetoxified bran component, the detoxified bran component having inorganic arsenic up to 0.2 mg/kg by weight, wherein the detoxified bran component comprises dimethylarsenate (DMA), and wherein the more than 90% of the inorganic arsenic present in the bran is converted into DMA.
2 . The detoxified bran composition of claim 1 , which has a level of inorganic arsenic reduced by at least about 95% relative to an undetoxified bran composition.
3 . The detoxified bran composition of claim 1 , the detoxified bran component being selected from a rice bran component, corn bran component, wheat bran component, oat bran component, barley bran component, rye bran component, and millet bran component.
4 . The detoxified bran composition of claim 1 , the detoxified bran component being at least about 60% of the detoxified bran composition by weight.
5 . A grain product comprising the detoxified bran composition of claim 1 .
6 . The grain product of claim 5 , further comprising at least one other component and/or other ingredient.
7 . The grain product of claim 6 , the other component being selected from an endosperm component and a germ component.
8 . The grain product of claim 6 , the other ingredient being selected from flavorings, oils, emulsifiers, preservatives, colorants, texturizers, and functional additives.
9 . A food product that is made from the grain product of claim 5 .
10 . The food product of claim 9 , the food product being a bakery product selected from cookies, crackers, pizza crusts, pie crusts, breads, bagels, pretzels, brownies, muffins, waffles, pastries, cakes, quickbreads, sweet rolls, donuts, fruit and grain bars, tortillas, and parbaked bakery products.
11 . The detoxified bran composition of claim 1 , the detoxified bran component having inorganic arsenic up to about 0.1 mg/kg by weight.
12 . The food product of claim 9 , the food product being un-baked products, frozen products, confectionery, dairy products, cream-based sauces and soups, dressings and dips, beverages, spice emulsions, baby food, dietary supplements, or animal foods.
13 . The food product of claim 9 , the food product comprising one or more additives selected from phytochemicals, vitamins, minerals, fatty acids, oils, amino acids, and probiotics.
14 . The food product of claim 9 , the food product further comprising glycerol, sorbitol, enzyme lignin, insoluble fiber, and/or soluble fiber.
15 . The grain product of claim 5 , the grain product being a dry product containing up to about 2% by weight of water or other solvent.
16 . The grain product of claim 5 , the grain product being ground to have an average particle size in the range of about 100 μm to 700 μm.
17 . The grain product of claim 8 , the functional additives being selected from probiotics, prebiotics, omega-3 fatty acids, antioxidants, and minerals.
18 . The detoxified bran composition of claim 1 , the detoxified bran component having inorganic arsenic up to about 0.05 mg/kg by weight.
19 . A detoxified bran composition comprising a detoxified bran component having inorganic arsenic up to about 0.1 mg/kg by weight, wherein the detoxified bran component comprises dimethylarsenate (DMA).
20 . A grain product comprising the detoxified bran composition of claim 19 .
