Abstract

The species Capsicum chinense, variety biquinho, has been gaining space in cooking, but little is known about its cultivars, mainly related to the chemical composition of fruits. The objective of this study was to characterize the nutritional composition of two biquinho pepper cultivars in different growing seasons and to define the relationships between the variables and their direct and indirect effects. An experiment was conducted in a randomized block design with two cultivars of biquinho pepper, two growing seasons. The variables were plastochron (PLAS), fruit mass (MASS), pH, total soluble solids (Brix), acidity, total phenolic compounds (PHE), carotenoids (CAR), antioxidant potential (ANT), capsaicin (CAP), and dihydrocapsaicin (DIH). The cultivar BRS Moema showed higher levels for chemical compounds, while the cultivar Airetama was the most productive. Principal component analysis (PCA) was performed to determine relationships among variables, and path analysis was used to determine direct and indirect effects between variables. The chemical composition of biquinho pepper is modified according to cultivar and growing season. Important relationships between pH and CAR, ANT, PHE, CAP, and pH. CAR and PHE have an indirect effect and the MASS and PLAS have a direct effect on the ANT.
