Abstract
Abstract The adverse effects of chlorine upon the bread making properties of flour are ameliorated by incorporating therein a definite, selected amount of a sulfhydryl-containing-or-producing reducing substance, preferably cysteine hydrochloride. The flours so obtained, at chlorine levels of between about 150 p.p.m. and about 900 p.p.m. and a reducing substance content of between about 20 p.p.m. and 100 p.p.m., provide improved all-purpose flours which give good results in the contrasting applications of bread and cake making. Further advantageous effects on the quality of the baked product can be obtained by including defined amounts of ascorbic acid type additives and/or oxidizing agents such as bromate or iodate salts.

Claim 1
Independent Claim
83 words
An improved all-purpose flour, said flour having been treated with chlorine to a level of between about 150 and about 900 p.p.m., based on the flour weight and, as functional additives intimately blended therewith, between about 20 and about 100 p.p.m., based on the flour weight, of a substance selected from the group consisting of sulfhydryl-containing and sulfhydryl-producing reducing substances, along with between about 20 and about 100 p.p.m., based on the flour weight, of ascorbic acid or an ascorbic acid type substance.
Claim 2
Dependent Claim
79 words

Claim 3
Dependent Claim
22 words
An improveD all-purpose flour as claimed in claim 3 wherein said mild oxidizing agent is a bromate salt or an iodate salt.
Claim 4
Dependent Claim
58 words
An improved all-purpose flour, said flour having been treated with chlorine to a level of between about 350 and about 700 p.p.m., based on the flour weight and containing, intimately blended therewith, between about 50 and about 90 p.p.m., based on the flour weight, of a substance selected from the group consisting of sulfhydryl-containing and sulfhydryl-producing reducing substances.
Claim 5
Dependent Claim
14 words
