Abstract: The present invention relates to novel applications of hop acids and formulations using hop acids. More specifically, the present invention relates to formulations comprising hop acids to stabilise or emulsify hop oils or other essential oils in aqueous media. We describe an aqueous emulsifiable composition comprising 0.01-5.00 wt % of at least one essential oil and 0.005-10.0 wt % of at least one hop acid, the balance being water. We also describe a method of stabilising or emulsifying an essential oil or mixture of essential oils. The method comprises mixing the essential oil or mixture of essential oils with at least one hop acid to form an essential oil and hop acid mixture and mixing the essential oil and hop acid mixture with water. We further describe the use, as an emulsifier, of a composition comprising at least one hop acid and beverages obtainable with the composition.

Abstract: The invention relates to a method for controlling biological processes, particularly digestion processes in water, particularly in stagnant or flowing water systems, whereby a certain quantity of tree resins is added to the water.

Abstract: The invention relates to a method for controlling microorganisms in a sugar-containing aqueous process medium, especially in the sugar industry, using hop bitter acid as active substance. The hop bitter acid is dissolved in an aqueous alkaline medium and added to the process medium. The pH value of the added solution is higher than the pH value of the process medium and the hop bitter acid passes from the dissociated to the indissociated form in the process medium.
