Abstract

A fermented flour having an improved mouthfeel and taste includes a reduced concentration of off-flavor compounds. Methods of reducing the off-flavored compounds concentration in a flour include fermenting the flour under solid state fermenting conditions.

First claim

1 . A fermented flour comprising:
less than about 500 ng/g of hexanal, less than about 10 ng/g of pentanal, less than 0.5 ng/g of decanal; and, one or more deactivated microorganisms selected from the group consisting of Lactobacillus Lactis, Streptococcus thermophiles, Lactobacillus delbrueckii, Lactobacillus acidophilus, Lactobacillus paracasei, Lactobacillus casei, Bifidobacterium animalis, Lactobacillus rhamnosus, Lactococcus lactis ssp. lactis, Lactococcus lactis ssp., Lueconostoc mesenteroids, Lactococcus lactis ssp. lactis, Lactobacillus sakei, Lactobacillus planetarium , and Kluyveromyces marxianus wherein the fermented flour has a moisture content less than about 6.5%.

2 . The fermented flour of claim 1 further comprising:
less than about 40 ng/g of heptanal;
less than 0.5 ng/g of decanal;
less than about 30 ng/g of nonanal;
between about 10 ng/g to about 100 ng/g of Benzaldehyde;
less than about 25 ng/g of 3-methylbutanal;
between about 1 ng/g and about 3 ng/g of 2,3-dimethyl-5-ethylpyrazine; and
less than about 10 ng/g of methylpyrazine.

3 . The fermented flour of claim 1 further comprising less than about 10 ng/g of trans,trans-2,4-octadienal.

4 . The fermented flour of claim 1 , wherein the fermented flour has less than about 1 ng/g of pentanal.

5 . The fermented flour of claim 1 further comprising about 1 ng/g to about 5 ng/g of phenylacetaldehyde.

6 . The fermented flour of claim 1 further comprising less than about 0.5 ng/g of methyl acetate.

7 . The fermented flour of claim 1 further comprising less than about 10 ng/g of 1-pentanol.

8 . The fermented flour of claim 1 further comprising between about 1 ng/g to about 500 ng/g of diisobutyl ketone.

9 . The fermented flour of claim 1 , wherein the fermented flour includes chickpeas.

10 . A method to reduce the concentration of flavor compounds in a flour comprising:
combining the flour with a liquid to form a mixture having about 35 wt. % to about 55 wt. % flour; seeding the mixture with at least one microorganism to form a seeded mixture, wherein the microorganism is not heterofermentative; fermenting the seeded mixture at a temperature ranging between about 65° F. to about 110° F. for about 2.5 hours to about 17 hours to form a fermented material having a reduced concentration of hexanal ranging from about 0 ng/g to about 500 ng/g.

11 . The method of claim 10 , wherein the flour is formed from a grain, a pulse, a seed, or a combination thereof.

12 . The method of claim 10 , wherein the mixture includes between about 0.001 wt. % to about 10 wt. % added sugar.

13 . The method of claim 10 , wherein the at least one microorganism is selected from the group consisting of Lactobacillus Lactis, Streptococcus thermophiles, Lactobacillus delbrueckii, Lactobacillus acidophilus, Lactobacillus paracasei, Lactobacillus casei, Bifidobacterium animalis, Lactobacillus rhamnosus, Lactococcus lactis ssp. lactis, Lactococcus lactis ssp., Lueconostoc mesenteroids, Lactococcus lactis ssp. lactis, Lactobacillus sakei, Lactobacillus planetarium , and Kluyveromyces marxianus.

14 . The method of claim 10 , wherein the flour includes pre-gelled starch prior to combining with a liquid to form a mixture.

15 . The method of claim 10 , wherein the flour is extruded prior to combining with a liquid to form a mixture.

16 . The method of claim 10 further comprising drying the fermented material to produce a fermented flour.

17 . A food product formed from a dough comprising i) a fermented flour containing less than about 500 ng/g of hexanal, less than about 10 ng/g of pentanal, and less than 0.5 ng/g of decanal; and ii) a non-fermented flour.

18 . The food product of claim 17 , wherein the fermented flour further includes less than about 40 ng/g of heptanal, less than about 30 ng/g of nonanal, between about 10 ng/g to about 100 ng/g of benzaldehyde, less than about 25 ng/g of 3-methylbutanal, between about 1 ng/g and about 3 ng/g of 2,3-dimethyl-5-ethylpyrazine, and less than about 10 ng/g of methylpyrazine.

19 . The food product of claim 17 , wherein the dough includes a weight ratio of the fermented flour to the non-fermented flour of about 1:1, about 2:1, about 3:1, about 4:1, about 5:1, about 6:1, about 7:1, or about 8:1.

20 . The food product of claim 19 , wherein the fermented flour is produced using a chickpea flour.
