The present invention relates to a capsule comprising at least two compartments, including a first compartment and a second compartment; wherein the first compartment comprises 5-30 mL of an aqueous liquid having an ethanol content of 0-10% ABV and comprising 0.1-25wt. % of protein; and wherein the second compartment comprises 5-50 mL of an alcoholic liquid containing 20-99.9 wt. % ethanol, 0-60 wt. % water, and 50-2,000 mg/kg of hop acids acids selected from iso-alpha acids, hydrogenated iso-alpha acids, hulupones and combinations thereof, and wherein ethanol and water together constitute at least 80 wt. % of the alcoholic liquid.

The capsule can suitably be used to prepare a hopped alcoholic beverage with a foam head, similar to ordinary beer. To prepare such a beverage, the contents of the capsule are combined with carbonated water and dispensed into a e.g. a drinking glass.

The present invention disclosed a bio-based polymer additive, its preparation process and a biodegradable polymer composition comprising the said bio-based polymer additive for use in manufacturing of biodegradable plastic. The said additive is prepared from the biomass of broken microorganism cell such as microalgae, yeast or other microorganisms. In particular, the bio-based polymer additive is for enhancing rheological properties and/or biodegradability of a polymer. In particular, the additive is for use as a pigment.

The present invention provides a method for preparing a colour-stable preparation of a magnesium chlorophyllin alkali metal salt or alkali earth metal salt from natural sources of chlorophyll. The invention further provides a colour-stable and substantially pure pigment composition comprising a vibrant green magnesium chlorophyllin in the form of an alkali metal or alkali earth metal salt, e.g. those prepared by the methods of the invention, and the use of the salts and compositions of the invention as colouring agents, in particular as food colouring agents, and as medicaments and disinfectants.

Provided herein is an effervescent beer containing 0.005-0.17 mg/ml riboflavin such that the beer fluoresces upon exposure to light having an emission spectrum of about 100-500 nm. The riboflavin may be added alone or in combination with one or more additional agents to enhance the flavor, intensity and/or color of the light. Methods of producing such beers are also provided.
