This study reports for the first time the metabolic profile of cocoa (Theobroma cacao L.) beans using the (1)H NMR technique applied to polar extracts of fermented cocoa beans. The simultaneous detection and quantification of amino acids, polyalcohols, organic acids, sugars, methylxanthines, catechins, and phenols were obtained by assigning the major signals of the spectra for different varieties of cocoa beans (Forastero, Criollo, and Trinitario) from different countries (Ecuador, Ghana, Grenada, and Trinidad). The data set obtained, representative of all classes of soluble compounds of cocoa, was useful to characterize the fermented cocoa beans as a function of the variety and geographic origin.
本研究首次报告了使用氢核磁共振(¹H NMR)技术对发酵可可豆的极性提取物进行分析得到的可可(Theobroma cacao L.)豆代谢谱。通过对来自不同国家(厄瓜多尔、加纳、格林纳达和特立尼达)的不同品种可可豆(福拉斯特罗、克里奥洛和特立尼塔里奥)光谱中的主要信号进行归属,实现了对氨基酸、多元醇、有机酸、糖类、甲基黄嘌呤、儿茶素和酚类物质的同时检测和定量。所获得的数据集代表了可可的所有可溶性化合物类别,有助于根据品种和地理来源对发酵可可豆进行表征。
