Abstract: A beer beverage comprising 4-vinyl phenol (4VP) and 4-vinyl guaiacol (4VG) in the 4VG:4VP weight ratio of from 2.5-10, the overall weight proportion of 4VG and 4VP in the beverage being from 0.1 ppm to 0.6 ppm. The compounds provide desirable beer flavor characteristics to both beers and non-alcoholic beer beverages deficient in these characteristics.

Abstract: This invention relates to a method for inhibiting melanin formation in a subject comprising administering an effective amount of an acerola-derived polyphenol compound, an acerola polyphenol fraction, or the other polyphenol compound to a subject. This method comprises whitening the subject's skin by the inhibition of melanin formation. This method also comprises administering synergistically effective amounts of an acerola-derived polyphenol compound, an acerola polyphenol fraction, or the other polyphenol compound in combination with ascorbic acid or an ascorbic acid derivative to a subject.

Abstract: This invention provides an inhibitor of glucose absorption and a method for producing the same. Such inhibitor of glucose absorption comprises, as an active ingredient, an acerola-derived substance capable of inhibiting glucose absorption.
