Claims20
An aqueous composition comprising:
- (a) at least one first organic acid and
- (b) at least one second organic acid wherein the first organic acid is different from the second organic acid.
A method of controlling undesirable microorganism concentration in an aqueous system employed in a fermentation process, the method comprising the steps of:
- (a) introducing a fermentable carbohydrate to an aqueous solution;
- (b) introducing at least one yeast to said solution;
- (c) introducing a first organic acid and a second organic acid said into the aqueous system.
A method of controlling undesirable microorganism concentration in an aqueous fluid solution employed in a fermentation process, the method comprising the steps of:
- (a) introducing a fermentable carbohydrate to an aqueous solution;
- (b) introducing at least one desirable microorganism which is capable of fermenting carbohydrate to said aqueous solution;
- (c) introducing at least one hops acid extract into said aqueous solution;
- and
- (d) introducing at least one organic acid into said aqueous solution.
