Chindapan, Nathamol published the artcileProfiles of volatile compounds and sensory characteristics of Robusta coffee beans roasted by hot air and superheated steam, Safety of 2,3,5-Trimethylpyrazine, the main research area is Robusta coffee bean volatile compound hot air superheated steam.
Although superheated steam (SHS) roasting has proved to be capable of improving selected quality of roasted Robusta coffee beans, impact of SHS roasting on aroma characteristics of the beans is not well understood. This study therefore aimed to investigate the effect of SHS roasting on aroma profiles and sensory characteristics of Robusta beans undergone SHS roasting at 190-250°C; results were compared with those of beans roasted by hot air (HA). Sensory characteristics of selected samples were also compared with HA-roasted Arabica beans. Forty five aroma compounds were identified; most were fully developed in beans roasted at 230°C and tended to degrade in beans roasted at 250°C. The SHS roasting led to more extensive formation of aroma compounds contributing to caramel note, while helped reduce formation of major contributors to spicy, roasty and burnt notes. The SHS-roasted Robusta beans exhibited more resemblance to Arabica beans than their HA-roasted counterpart.
