摘要: Ellagitannins, the main components of walnut kernel polyphenols, are easily degraded by heating to produce ellagic acid, precursor in the production of urolithins that show multiple physiological functions. To analyze the conversion of ellagitannins to free ellagic acid in walnut kernels during baking, a quantitative method was developed to investigate the ellagic acid content (EAC) in free phenolic acid (FPA), acid-hydrolyzable phenolic acid (AHPA), and bound phenolic acid (BPA) fractions. The results showed that the EAC in FPA reached its maximum (5.17 ± 0.30 mg/g DW) after baking at 165 °C for 30 min, which increased by 99.52% compared with the control. Meanwhile, the content of ellagitannins (ETC) in AHPA and BPA dropped by 89.14% and 26.08%, respectively. It suggested that baking promoted the conversion of ellagitannins in AHPA and BPA to ellagic acid in FPA. Eight ellagitannins were regarded as the main precursors of ellagic acid in walnut kernels. © 2022 Elsevier Ltd
