Abstract

Coffee cherry pulp is a by-product obtained during coffee production. Coffee cherry pulp contains considerable amounts of phenolic compounds and caffeine. An attempt to produce Cascara, a refreshing beverage, has been made. Six dried coffee pulp samples and a beverage called Cascara produced in Switzerland out of one of those samples were investigated. Aqueous extraction of coffee pulps revealed a content of total polyphenols between 4.9 and 9.2mg gallic acid equivalents (GAE)/gDM. The antioxidant capacity was between 51 and 92μmol Trolox equivalents (TE)/gDM as measured by the assay with ABTS radical. Bourbon variety from Congo and maragogype variety showed highest caffeine contents with 6.5 and 6.8mg/gDM. In all samples chlorogenic acid, protocatechuic acid, gallic acid and rutin were present. The beverage Cascara contained 226mg/L of caffeine and 283mgGAE/L of total polyphenols whereas antioxidant capacity amounted to 8.9mmol TE/L.

摘要

咖啡樱桃果肉是咖啡生产过程中获得的一种副产品。咖啡樱桃果肉含有大量的酚类化合物和咖啡因。人们已尝试生产一种名为卡斯卡拉的提神饮料。对六个干燥咖啡果肉样品以及用其中一个样品在瑞士生产的名为卡斯卡拉的饮料进行了研究。咖啡果肉的水提取显示，总多酚含量在4.9至9.2毫克没食子酸当量（GAE）/克干物质之间。通过ABTS自由基测定法测得的抗氧化能力在51至92微摩尔Trolox当量（TE）/克干物质之间。来自刚果的波旁品种和马拉戈日皮品种的咖啡因含量最高，分别为6.5和6.8毫克/克干物质。所有样品中均含有绿原酸、原儿茶酸、没食子酸和芦丁。卡斯卡拉饮料含有226毫克/升的咖啡因和283毫克GAE/升的总多酚，而抗氧化能力达8.9毫摩尔TE/升。
