Abstract

An environmentally friendly method for the release of cocoa bean shell (CBS) extracts is proposed in this paper. This work aims to investigate the effect of pulsed electric field (PEF) pre-treatment on subsequent solid-liquid extraction (SLE) of metabolites with choline chloride-lactic acid natural deep eutectic solvent (NaDES) and bioactivity of cocoa bean shell (CBS) extract. Two different media for PEF application were evaluated: water and chlorine chloride-lactic acid. Total polyphenols (TPC), total flavonoids (TFC), individual major compounds, and antioxidant and antibacterial activity of CBS extracts were assessed. The performance of PEF-assisted extraction was compared with SLE and ultrasound-assisted extraction (UAE). The proposed method improved the release of TPC up to 45% and TFC up to 48% compared with the conventional extraction. The CBS extract showed medium growth inhibition of Escherichia coli and high growth inhibition of Salmonella sp, Listeria monocytogenes, and Staphylococcus aureus. Thus, an extract with enhanced antioxidant and antibacterial properties was obtained.

用氯化胆碱-乳酸天然深共晶溶剂萃取法辅助脉冲电场预处理，改善可可（可可豆）豆壳提取物的成分和生物活性。

本文提出了一种环境友好型可可豆壳（CBS）提取物释放方法。这项工作旨在研究脉冲电场（PEF）预处理对氯化胆碱-乳酸天然深共晶溶剂（NaDES）固液萃取（SLE）代谢物的影响以及可可豆壳（CBS）提取物的生物活性。评估了两种不同的 PEF 应用介质：水和氯化胆碱-乳酸。评估了可可豆壳提取物的总多酚（TPC）、总黄酮（TFC）、单个主要化合物以及抗氧化和抗菌活性。比较了 PEF 辅助萃取与 SLE 和超声辅助萃取（UAE）的性能。与传统提取法相比，所提议的方法提高了 TPC 的释放率达 45%，提高了 TFC 的释放率达 48%。CBS 提取物对大肠杆菌的生长抑制率中等，对沙门氏菌、李斯特菌和金黄色葡萄球菌的生长抑制率较高。因此，萃取物具有更强的抗氧化和抗菌特性。

期刊介绍： Plant Foods for Human Nutrition (previously Qualitas Plantarum) is an international journal that publishes reports of original research and critical reviews concerned with the improvement and evaluation of the nutritional quality of plant foods for humans, as they are influenced by: - Biotechnology (all fields, including molecular biology and genetic engineering) - Food science and technology - Functional, nutraceutical or pharma foods - Other nutrients and non-nutrients inherent in plant foods
