Evaluation of volatile compounds in coffee (Coffea arabica L.) beans in response to biochar applications using an electronic nose

The use of biochar (BC) seems to be a promising alternative for efficient and environmentally friendly waste management that could help promote cleaner agricultural production. objective this research was evaluate the aromatic profile coffee (Coffea arabica L.) beans cup quality parameters in response application four different doses (0, 4, 8, 16 t ha-1) obtained from pulp, levels chemical fertilization (CF) (0%, 33%, 66% 100% nutritional requirements). An electronic nose used analyze volatile compounds their relationship with parameters: Soluble solids (TSS), pH, titratable acidity. Applications 8 ha-1 BC CF registered greater sensitivity roasted sensors W1C, W3C, W5C. amendments between increased TSS content (CF 66%: 1.32 °Brix 100%: 1.38 °Brix), reduced pH 4.95 4.88) acidity 697.88 mg CaCO3 L-1 662.56 L-1) beverages ‘Castillo El Tambo’ bean year 2020. Finally, co-application as complement showed positive effect on profile. This methodology an original approach characterize according crop’s status, helping factors focused traceability.
