Résumé
Although coffee beans have been widely studied, application of coffee flower (CF) has not been previously investigated. Here, we evaluated the use of CF for the production of bioactive compounds, melanoidins, and bio-sugars through the green process. Pressurized hot water extraction was found to be the most appropriate method for extracting bioactive compounds from CF, which contain high values of total phenolic content and have antioxidant properties. Caffeine and trigonelline were the main compounds in CF with yields of 1070.8 mg and 1092.8 mg/100 g dry weight (DW), respectively. Melanoidins were also identified and quantified in the CF extracts that is approximately 30.2% were efficiently recovered in the initial extracts of CF. Bio-sugar was also obtained from cellulase and pectinase at a 92.8% conversion rate. The aim of this study is to promote a novel approach using high amounts of CFs in the production of functional healthy foods and beverages.
