| Summary: | Capsaicinoids obtained from lyophilized serrano chili by sorbitan monooleate solutions were investigated. Sorbitan monooleate was as effective as methanol in extracting capsaicin and dihydrocapsaicin (DHC). Subsequently, a Box–Behnken design was used to optimize capsaicin, DHC, and polyphenol extraction, as well as to evaluate the antioxidant capacity of dehydrated serrano chili. Particle size (PS) (20–60 mesh), processing temperature (55–75 °C), and sorbitan concentration (1.5–2.5%) were selected as independent variables. The statistical analysis showed that the quadratic models adequately describe the response of the concentration of capsaicin and DHC, but not with polyphenols and antioxidant capacity. The highest extraction of capsaicin (~620 mg/100 g dw) and DHC (~520 mg/100 g dw) was achieved with the combination of sorbitan at 2%, temperature at 65 °C, and PS from 40 mesh. Experimental and predicted values were closely consistent. Meanwhile, extracts with the highest antioxidant potential (~7510 and ~5820 µM of Trolox Eq/100 g dw for ABTS and FRAP, respectively) were those extracted in sorbitan and PS from 40 mesh. In contrast, the highest values of polyphenols (~171 mg gallic acid Eq/100 g dw) were found in the extracts prepared at 75 °C. These results suggest that sorbitan monooleate solutions can be an effective, non-toxic, and environmentally responsible way to obtain capsaicinoids and bioactive compounds from dehydrated serrano chili. |
