Influence of the micro-oxygenation dose and supplementation with oak staves of different potential of ellagitannin release on wine color and composition

BIO Web of Conferences, 2019
Aliquots of a wine of Merlot were micro-oxygenated at two doses of oxygen (2.5 and 5.0 mg of O2/L.month) in the presence or not of oak staves of different potential ellagitannin release (PER) for three months.

The Oxygen Consumption Kinetics of Commercial Oenological Tannins in Model Wine Solution and Chianti Red Wine

Molecules, 2020
One property of oenological tannins, oxygen reactivity, is commonly exploited in winemaking. The reactivity is mediated by the presence of catalysts (i.e., transition metals and sulfur dioxide) and protects wine against oxidation.

Enzymatic oxidation of ellagitannin and a new ellagitannin metabolite from Camellia japonica leaves

Tetrahedron, 2017
Polyphenols in the leaves of Camellia japonica L. at different stages of growth were analyzed by HPLC. Pedunculagin [2,3; 4,6-bis-(S)-hexahydroxydiphenoyl-D-glucose] was the major polyphenol in the youngest leaves. The levels of this compound and (+)-catechin decreased as the leaves matured.
