Abstract

Ceylon cinnamon is a possible reserve of proanthocyanidins. This study aimed at the extraction and characterization of an extract rich in proanthocyanidins from Ceylon cinnamon. Extraction kinetics data were determined using hydroalcoholic solution as the solvent, different temperatures, and solid:solvent mass ratios up to 60 min. The extract obtained under the best conditions was analyzed by high-performance liquid chromatography/diode array detection, and the main fractions collected were evaluated by mass spectrometry and antioxidant capacity assays. Increases in temperature and solid:solvent ratio led to an increase in the effective diffusivity coefficient and proanthocyanidins extraction yield. The temperature of 60 degrees C and solid:solvent ratio of 1:7.5 during 30 min of extraction provided quick extraction of these compounds with a maximum yield of 99%. The main fractions collected were identified as being cinnamaldehyde, cinnamic acid, and oligomeric proanthocyanidins which yielded the highest antioxidant capacity. Therefore, this extract becomes potential for use as a functional ingredient. Novelty impact statement A rich proanthocyanidins extract of Ceylon cinnamon was obtained. Higher values of temperature and solid:solvent ratio improve the extraction. The extract contains mainly proanthocyanidins, cinnamic acid and cinnamaldehyde. Among the fractions, phenolics are the main antioxidant compounds. The obtained extract has potential to be used as a functional ingredient. (AU)
