Influence of soil type and ripening degree on the intensity and sensory dominance of Mexican habanero chili (Capsicum chinense Jacq.)

Abstract

The objective of this research was to determine the intensity and sensory dominance of habanero peppers grown in different types of soils and with different degrees of maturation. Chili samples grown in red soil (Mayan name: K'ankab lu'um) and black soil (Mayan name: Box lu'um) were evaluated in an immature state (green coloration) and intermediate ripening (green‐orange coloration) using descriptive analysis (DA) and temporal dominance of sensations (TDS). Sensory representation and classification percentage of chili peppers were evaluated using principal component analysis and discriminant factor analysis. The sensory results demonstrated that intermediate ripening chili peppers presented higher color intensities associated with pungency. Immature chili peppers were characterized by having high odor intensities. The TDS results showed that the dominant attributes were burn feeling, chili flavor, heat, and numbness. Immature chili peppers grown in black soil tend to be burn feeling dominant and chili peppers grown in red soil were characterized as chili flavor. The ripe habanero peppers were chili flavor burn feeling and heat. The correct classification percentage was 89.81%.Practical ApplicationsThis research exposes the sensory differences of habanero peppers with different degrees of maturation and grown in different types of soils. The findings can serve as a reference for future research on the sensory characterization of pungent and for the industry dedicated to the production of habanero chili and for the gastronomy area in charge of the preparation of different dishes that use habanero chili as an ingredient.
