Cocoa bean husk (CBH) is the principal by-product of the cocoa industry and a significant agro-industrial residue. In this study, using different hydrothermal treatments of CBH, it is shown that CBH is an important source of bioactive compounds, including theobromine, epicatechin and catechin.
Treatment over 150 °C significantly increased the yield of total and individual phenols and theobromine as well as the antioxidant capacity of the liquid fraction. A total of 52 different genotypes of CBH harvested in two seasons of production were analyzed. Overall, higher amounts of total phenols, theobromine and epigallocatechin were detected in samples from the 2015 season, while samples from 2014 had higher quantities of catechin and similar quantities of epicatechin.
CBH treatment at 170 °C for 30 min produces an antioxidant-rich extract high in phenols (55 mg g ), sugars (220 mg g ) and theobromine (56 mg g ) that is suitable for applications in the food, cosmetic and nutraceutical industries. © 2018 Society of Chemical Industry.
可可豆壳（CBH）是可可产业的主要副产物，也是重要的农业工业废料。本研究通过对 CBH 进行不同的湿热处理，表明 CBH 是生物活性化合物的重要来源，包括可可碱、表儿茶素和儿茶素。
150°C 以上的处理显著提高了总酚和各酚类物质以及液体部分的可可碱和抗氧化能力的产量。分析了两个生产季节收获的 52 种不同基因型的 CBH。总的来说，2015 季样品中总酚、可可碱和表没食子儿茶素的含量较高，而 2014 季样品中儿茶素和表儿茶素的含量较高。
170°C 处理 30 分钟的 CBH 可产生富含酚类物质（55mg/g）、糖（220mg/g）和可可碱（56mg/g）的抗氧化丰富提取物，适用于食品、化妆品和营养保健品行业。 © 2018 化学工业协会。
