Abstract

The aim of this work was to estimate the intestinal bioaccessibility of polyphenols and antioxidant capacity of cactus pear using an in vitro gastrointestinal model. The amount of polyphenols released from the food matrix by the action of digestive enzymes was about 69-83% in pulp and 0-14% in seeds. The rest of polyphenols was associated with indigestible compounds conferring antioxidant capacity. The results suggest that these compounds could reach the colon and induce healthy effects.

摘要

本工作旨在使用体外胃肠道模型来评估仙人掌果实中多酚的肠道生物利用度和抗氧化能力。消化酶作用下从食物基质中释放的多酚量在果肉中约为 69-83%，而在种子中为 0-14%。其余的多酚与赋予抗氧化能力的不可消化化合物相关联。研究结果表明，这些化合物可能到达结肠并产生健康效应。
