A fermentation process for the production of ethanol from natural sources, such as corn, comprising introducing a fermentable sugar, an inoculant, and a stabilized chlorine dioxide into a fermentation system is disclosed. The stabilized chlorine dioxide is added preventatively to the fermentation system, at concentrations in the fermentation system of acetic acid no greater than 0.30% (weight/volume) and lactic acid no greater than 0.60% (weight/volume). The stabilized chlorine dioxide is added in an amount effective to substantially prevent growth of bacteria.

Prevention of bacterial growth in fermentation processes

A process to preserve a carbohydrate feedstock against contaminant microorganisms comprises contacting the carbohydrate feedstock with a stabilized chlorine dioxide at a pH of at least 2.6. The carbohydrate feedstock preferably comprises a naturally-occurring carbohydrate, particularly a carbohydrate having a reducing end group. The process is particularly suitable to treat feedstocks used in biorefining processes, such as in ethanol fermentation.

Stabilized chlorine dioxide to preserve carbohydrate feedstocks

A process for making stable and uniformly dispersed oil-in-water beverage emulsions is provided. The process comprises combining an oil mixture and an aqueous mixture to form a beverage pre-emulsion; in-line mixing of the beverage pre-emulsion; and homogenizing of the beverage pre-emulsion to form a stable and uniformly dispersed beverage emulsion.
