Abstract

A method of decontaminating grain, nut, or seed products and a method for conditioning grain in a milling process for decontamination and to produce an improved milled product which will yield baked goods, for example, of increased size and extended shelf life. In the decontamination and/or conditioning procedure, the grain, nut, or seed product is contacted with an aqueous anolyte product which can be undiluted or can be diluted with non-activated water. In undiluted form, the aqueous anolyte product preferably has a pH in the range of from about 4.5 to about 7.5 and a positive oxidation-reduction potential of at least ⁺550 mV.

Claims

1. A method of processing grain comprising the steps of:

(a) applying an aqueous conditioning fluid to said grain, prior to milling, in a manner effective to increase a moisture content of said grain without causing said moisture content of said grain to exceed 20% by weight, said aqueous conditioning fluid at least partially comprising an aqueous anolyte product wherein, when in undiluted form, said aqueous anolyte product has a pH in a range of from about 5.5 to about 7.5 and a positive oxidation-reduction potential of at least ⁺550 mV and then

(b) dry milling said grain to produce a milled product,

said process being conducted at ambient conditions during step (a) and between step (a) and step (b) and

said aqueous anolyte product being present in said aqueous conditioning fluid in an amount effective to at least reduce growth of toxigenic fungi on said grain.

2. The method of claim 1 further comprising the steps, after step (a) and prior to step (b), of:

removing at least an outer layer from said grain and

removing a grain germ material from said grain.

3. The method of claim 1 wherein said aqueous conditioning fluid is a diluted anolyte composition comprising said aqueous anolyte product and non-electrochemically activated water, said aqueous anolyte product being present in said diluted anolyte composition in a concentration of at least 1% by weight and said non-electrochemically activated water being present in said diluted anolyte composition in a concentration of at least 50% by weight.

4. The method of claim 1 wherein said aqueous anolyte product has a free active oxidant concentration of less than 250 ppm.

5. The method of claim 1 wherein said aqueous anolyte product is an anode product which has been produced by electrochemical activation of an aqueous salt solution comprising from about 1 to about 9 grams of salt per liter of water, wherein said salt is sodium chloride, sodium carbonate, or sodium bicarbonate.

6. The method of claim 1 wherein, when in undiluted form, said aqueous anolyte product has a positive oxidation-reduction potential of at least ⁺650 mV.

7. The method of claim 1 wherein, when in undiluted form, said aqueous anolyte product has a pH in a range of from about 6.5 to about 7.5.

8. The method of claim 1 wherein said moisture content of said grain is increased in step (a) to a value in a range of from 13% to 18% by weight.

9. The method of claim 1 wherein said moisture content of said grain prior to step (a) is sufficiently low that said toxigenic fungi are dormant prior to said aqueous conditioning fluid being applied to said grain in step (a).

10. The method of claim 1 wherein said grain is wheat grain.

11. The method of claim 1 wherein step (a) comprises:

spraying said aqueous conditioning fluid onto said grain and

agitating said grain such that said aqueous conditioning fluid is absorbed by said grain.

12. In a method comprising the steps of forming a dough comprising flour and yeast and baking said dough to produce a baked product having a finished volumetric size per a given weight amount of said flour used in forming said dough, the improvement comprising said flour used in forming said dough being a flour product which was produced by a process comprising the steps of:

(a) applying an aqueous conditioning fluid to grain, prior to milling, in a manner effective to increase a moisture content of said grain without causing said moisture content of said grain to exceed 20% by weight, said aqueous conditioning fluid at least partially comprising an amount of an aqueous anolyte product wherein, when in undiluted form, said aqueous anolyte product has a pH in a range of from about 5.5 to about 7.5 and a positive oxidation-reduction potential of at least ⁺550 mV and then

(b) milling said grain,

wherein said aqueous anolyte product being present in said aqueous conditioning fluid used in step (a) is in an amount effective for altering a fermentable sugar composition of said flour product in a manner such that said finished volumetric size of said baked product per said given weight amount of said flour used in forming said dough is increased.

13. The method of claim 12 wherein said amount of said aqueous anolyte product in said aqueous conditioning fluid is effective for altering said fermentable sugar composition of said flour product in a manner such that said finished volumetric size of said baked product per said given weight amount of said flour used in forming said dough is increased by at least 6.78%.

14. The method of claim 12 wherein said amount of said aqueous anolyte product in said aqueous conditioning fluid is effective for altering said fermentable sugar composition of said flour product in a manner such that said finished volumetric size of said baked product per said given weight amount of said flour used in forming said dough is increased by at least 9.15%.

15. The method of claim 12 wherein said amount of said aqueous anolyte product in said aqueous conditioning fluid is effective for altering said fermentable sugar composition of said flour product in a manner such that said finished volumetric size of said baked product per said given weight amount of said flour used in forming said dough is increased by at least 10.53%.

16. The method of claim 12 wherein said process which was used for forming said flour product further comprised the steps, after step (a) and prior to step (b), of:
