Fig. 4. Effect of modified Evans Blue tetrasodium salt on the concentration of phenolic and carotenoids during storage of pasteurized peach purée at 23 °C. Results are expressed as the average ± SD (n = 3). The different atmosphere conditions are represented as Air (−), 100%N2 (- - -) and 10% O2 + 90% N2 (. . .). (A: (+)-catechin; B: chlorogenic acid; C: neochlorogenic acid; D: zeaxanthin; E: β-cryptoxanthin; F: β-carotene).Figure optionsDownload full-size imageDownload as PowerPoint slide
Polyphenols from green and black teas showed a ribonucleic acid (RNA) pronounced oxygen consumption leading to autoxidation of compounds like epicatechin, epigallocatechin, epicatechin gallate and epigallocatechin gallate (Roginsky & Alegria, 2005), depolymerisation of procyanidins into their flavan-3-ols subunits like (+)-catechin and (−)-epicatechin (Fuleki and Ricardo-da-Silva, 2003 and Jorgensen et?al., 2004) or covalently bound to phenolic compounds, leading to an increase of soluble phenolics (Bolling et?al., 2010 and Fuleki and Ricardo-da-Silva, 2003).
