A method for preparing an extract containing gallic acid includes performing an extraction treatment on plants or plant constituents containing tannins by means of water or an aqueous system in the presence of the enzyme tannase to obtain a product mixture containing gallic acid. Further disclosed is a method for preparing an extract containing gallic acid, comprising performing an extraction treatment on plants or plant constituents containing tannins by means of a mixture containing a polar organic solvent and water to obtain a product mixture containing polyphenols, separating the plants or plant constituents from the product mixture to obtain a liquid extract, removing the polar organic solvent from the liquid extract, and treating the aqueous extract with the enzyme tannase to obtain an aqueous system containing gallic acid. In addition, the disclosure includes an aqueous concentrate containing gallic acid and a foodstuff or food supplement comprising the aqueous concentrate.

A combination is provided comprising an ellagitannin composition, and an enzymatic composition comprising one or more ellagitannin enzymes, where the one or more ellagitannin enzymes comprise a tannin acyl hydrolase enzyme, a gallate decarboxylase enzyme, or a combination thereof. Methods of making and using combinations disclosed herein are also provided.

A method to prepare and/or isolate water soluble anthocyanins is provided.

A combination is provided comprising an ellagitannin composition, and an enzymatic composition comprising one or more ellagitannin enzymes, where the one or more ellagitannin enzymes comprise a tannin acyl hydrolase enzyme, a gallate decarboxylase enzyme, or a combination thereof. Methods of making and using combinations disclosed herein are also provided.

Provided is a method for safely and selectively producing a substrate culture product including a large amount of a desired degrading enzyme. A method for producing a substrate culture product used for feedstuff includes inoculating filamentous fungi bred so that a target degrading enzyme is produced by self-cloning in high productivity on a substrate, and producing the substrate culture product having functionality by ventilating the substrate to carry out solid culture.

The present specification provides, in one aspect, a method of treating or inhibiting infection of a plant by a plant pathogen. The method includes contacting the plant with an amount of a cranberry composition effective to inhibit the plant pathogen. In another aspect, the present specification provides a composition for treatment of a plant disease. The composition includes a cranberry composition and a carrier that delivers the cranberry composition to at least a portion of a phloem of a citrus plant.
