Method for modifying polyphenol containing plant materials and medical uses of modified polyphenol plant containing materials

摘要

The present invention relates to a method for modifying polyphenol containing plant material(s), wherein said method comprises: mixing at least one polyphenol containing material and at least one solvent to provide a mixture; heating the mixture to eliminate bacterial species present to provide a heated mixture; adding at least one polyphenol modifying strain of lactic acid bacteria and optionally at least one protein source, in optional order or simultaneously, to the heated mixture to provide a fermentation mixture; and subjecting the fermentation mixture to conditions suitable for fermentation of the fermentation mixture to provide a mixture of modified polyphenol containing plant material(s); and optionally eliminating the polyphenol modifying strain of lactic acid bacteria to provide a mixture of modified polyphenol containing plant material(s) free from living lactic acid bacteria.

1. A method of lowering insulin response in a subject having diabetes, metabolic syndrome or obesity, comprising administering to the subject a fermented blueberry mixture in an amount effective for lowering insulin response in said subject, wherein said fermented blueberry mixture is prepared by a method comprising:
(a) mixing and homogenizing Vaccinium myrtillus blueberries and water to provide a homogenized mixture; (b) heating the homogenized mixture to 90° C. to 100° C. to eliminate bacterial species present to provide a heated mixture; (c) adding Lactobacillus plantarum HEAL 19 and at least one protein source selected from the group consisting of peptones, tryptones, yeast extracts and combinations thereof to the heated mixture to provide a fermentation mixture; and (d) fermenting the fermentation mixture for 10-30 hours at a temperature of 30° C.-50° C. to create a fermented blueberry mixture; wherein the insulin response in said subject, to which said fermented blueberry mixture has been administered, is lowered relative to an insulin response in an individual to whom said fermented blueberry mixture has not been administered.
