Capsicum chinense var. Biquinho presents a strong aroma without the burning pepper sensation. Headspace volatile compounds were isolated by SPME and analyzed by GC-FID, GC-MS, and GC-O. The major compounds profile showed similarity to the profile of spicier peppers, but several minor compounds presented high importance to Biquinho’s characteristic flavor. Aromagram showed 72 compounds; where α-cardinol, heptylisopentanoate, p-xylene, isohexanol, hexyl butanoate, and (Z)-3-hexenyl pentanoate may be potential markers for the sweet and mild pepper flavor of Biquinho. In future, genetic materials of other chili peppers may have crosses with this pepper, which will improve their sensory characteristics.
Brazilian geneticists are developing aromatic peppers that, besides their burning sensation, can also add flavor to foods. In this work, the volatile profiles of two new genotypes, CNPH 3931 and CNPH 4080, were compared to the profile of Orange Biquinho pepper, a very scented but not pungent Brazilian variety. Headspace volatile compounds were isolated by SPME and identified by GC-MS. The new genotypes presented very similar volatile profiles, with fewer compounds but higher volatile quantity when compared to Biquinho. They lack some important compounds to Biquinho’s aroma, but the presence of other esters can add a variety of desirable notes. These CNPH peppers were shown to be promising materials.
