Acrylamide control in cooked food products
The present disclosure relates to methods of reducing the formation of acrylamide in a thermally processed food product and to cooked food products with reduced acrylamide. The method comprises providing a food product or food intermediate in need of reduction of formation of acrylamide during thermal processing and applying a bran composition to the food product or food intermediate in an amount effective to reduce formation of acrylamide during thermal processing to a level that is lower than if the composition had not been applied.
1. A method of reducing the amount of acrylamide in a cooked food product, the method comprising:
providing a food product having free asparagine and a reducing sugar;
washing a bran composition having an arabinoxylan complex in an amount of from about 10% to about 40% by weight of the bran composition;
adding the bran composition to the food product; and
thermally processing the food product to form the cooked food product comprising acrylamide, wherein the amount of acrylamide in the cooked food product is reduced by at least about 20% lower than an amount of acrylamide in a similar cooked food product made without the bran composition;
wherein the step of adding, comprises adding from about 0.10 to 5 wt % of the bran composition to the food product, which is an amount that is sufficient to produce a final level of acrylamide in the cooked food product.
2. The method of claim 1 , further comprising a step of mixing the bran composition and the food product before the thermally processing step.
3. The method of claim 1 , wherein the bran composition comprises wheat, rye, barley, corn, flax, or combinations thereof.
4. The method of claim 1 , wherein the arabinoxylan complex further comprises an acid selected from cinnamic acid, ferulic acid, diferulic acid, caffeic acid, methoxyphenol, and mixtures thereof.
5. The method of claim 1 , wherein the step of thermally processing uses a temperature of about 120° F. to about 600° F. for a time of about 0.5 to about 30 minutes.
6. The method of claim 1 , wherein the free asparagine is present in an amount of about 0.5 mg/g to about 60.0 mg/g of the food product.
7. The method of claim 1 , wherein the reducing sugar is present in an amount of about 0.5 mg/g to about 50.0 mg/g of the food product on a dry weight basis.
8. The method of claim 1 , wherein the cooked food product has a moisture content of less than about 40% by weight based on the weight of the cooked food product.
9. The method of claim 1 , wherein the cooked food product is selected from the group consisting of crackers, breads, and chips, and wherein the cooked food product has an L-color from about 0 to about 6 and an A-color from about 0.5 to about 5, as determined using a Hunter Color Meter with an L-a-b color scale.
