A process for enhancing polyphenolics content of beverages brewed from polyphenolic containing, processed beverage substrate by pre-soaking substrate (coffee beans, for example) before roasting and then quenching the substrate after processing with the liquid in which the substrate was first 'pre-soaked.' Beverages produced from the treated substrate exhibit substantially increased polyphenolics content, when compared to conventionally processed beverage substrate of the same nature and processing.

Fresh tea leaves or green tea are converted to black tea using tyrosinase oxidation which alters catechines (a group of green tea polyphenols) to theaflavins. Theaflavins are unique black tea polyphenols and a potential anti-sunburn and chemopreventive agents. The oxidation reaction is performed on leaves which contain moisture only in an amount that the oxidation reaction occurs under the conditions of temperature of 20-50&deg; C., air or O (0.2 to 2 moles O /kg dry tea) supply and pH 5.0 to 7.5 at localized sites on and within the tea leaf structure. The moisture is supplied by moistening fresh tea leaves or dry green tea to a limited degree with a proper amount and concentration of monophenol, catechol and polyphenol oxidases, and tyrosinase, or their combinations. Obtained black tea contains much more theaflavins than regular black tea, and is, therefore, a more healthful beverage than that produced through use of conventionally processed black tea.

A process for increasing the levels of polyphenolic acid release into coffee which is brewed from beans which are bathed in an aqueous sodium bicarbonate solution shortly after roasting. The same process is applied to other polyphenolics containing beverage substrates, including teas. The bathing of beverage substrates (coffee beans and tea leaves, for example) with the aqueous sodium bicarbonate does not adversely change the taste of the produced beverage, and, in fact, in the case of coffee, such process actually extends the apparent freshness of coffee by inhibiting in the condensation of tannins in the coffee brew, thereby providing, not only the health benefits of the elevated levels of polyphenols, but a means to extend the freshness of the brewed beverage.

A new cocoa bean processing technique which, in stark contrast to conventional cocoa processing methods, preserves the beneficial flavanoid compounds of cocoa beans in finished, cocoa bean-based foodstuffs. The present method produces roasted cocoa beans that can be ground and the liquor can be either cooled and allowed to solidify (unsweetened chocolate) or pressed and re-ground to form cocoa powder. The resulting cocoa powder can then be used in a traditional manner to make sweetened chocolate products such as candy and beverages for consumption by humans or animals. The resulting products will be a source of flavanoid compounds, which are known antioxidants.
