Disclosed are methods and compositions for defoaming alcoholic fermentations. An aqueous composition of polydimethylsiloxane, an ethylene oxide/propylene oxide block copolymer and a silicone/silica blend is employed to treat the fermentation for foaming.

Defoamer and methods of use thereof

Methods and compositions for clarifying sugar are disclosed. Compositions of a condensation polymer of a dihaloalkyl compound and a dialkylamine compound and a phosphate compound are effective at clarifying the sugar syrup during its production as well as reducing the total amount of phosphate used.

Neutral phosphate pre-coagulant composition for clarification in white

An improved process for clarifying sugar syrup in the flotation system of a sugar making operation. Neutral phosphate-based compounds are added to the flotation system to aid in clarifying the sugar syrup. The use of the neutral phosphate-based compounds will eliminate the use of phosphoric acid and the commensurate need for neutralizing chemical as well as elimination of the tanks for phosphoric acid and neutralizing chemical mixing at field installations.
