The invention provides a novel class of natural red azaphilone pigments: cavernamines and their hydroxyl-derivatives; as well as the orange/yellow precursor cavernine. Additionally, methods for their production by fermentation using a fungal strain belonging to the species Aspergillus cavernicola, is provided; and further the use of the novel pigments as a colouring agent for food items and/or non-food items, and for cosmetics. The cavernamine pigments have the structure of Formula I or II, the hydroxyl-derivative of said cavernamine pigment has the structure of Formula III: Cavernine pigments having the structure of Formula IV or V are precursors f the cavernamine pigments I-III above.

Disclosed is a liquid production method and device for producing a liquid containing water-soluble components. The liquid production method includes extracting water-soluble components from a biological tissue, using a liquefied gas, to yield an extraction liquid, and vaporizing the liquefied gas from the extraction liquid obtained in the extracting to concentrate the extraction liquid.

A method of forming a colorant having a desired hue comprises mixing a component of a Huito fruit with an amino acid, thus forming a reaction mixture wherein the component of Huito fruit reacts with the amino acid and produces a blue color, and adjusting the hue of the blue color by adjusting the amount of oxygen present during reaction of the component of Huito fruit and the amino acid. The method may comprise adjusting a temperature of the mixing and/or other processing parameters.

Methods for obtaining natural colorants from plant material (e.g., tobacco material) and for using such natural colorants to dye various substrates are provided. Natural colorants are obtained using particular enzymes and particular conditions (e.g., time, temperature, and pH profiles). Such colorants can be used to dye substrates, for example, using conventional dyeing techniques or using unique in situ methods.

The present invention relates to a method to selectively produce metabolites from microalgae Galdieria sp. The method of the present invention comprises multiplying the biomass of the microalgae in mixotrophic and/or heterotrophic conditions with the presence of salts, separating the biomass, washing the biomass and inducing the production of metabolites, where the culture conditions of the metabolite production stage depend on the molecule that is desired to be obtained.
