Abstract: Volatile constituents and odor-active compounds of two varieties of Habanero pepper (Capsicum chinense Jacq.) were analyzed by GC-MS, GC-O and AEDA. A total of 118 volatile compounds were obtained from Habanero pepper varieties Mayapan and Jaguar by simultaneous distillation-extraction technique. Compounds such as esters, terpenes, aldehydes, alcs. and ketones comprised 78% of volatiles found in both varieties. By means of AEDA technique, 24 odor-contributing compounds (esters, terpenes, aldehydes and alcs.) were identified. Compounds such as δ-cadinene (FD = 729), 3-methylbutyl 2-methylpropanoate and 3,3-dimethylcyclohexanol (FD = 243) were the major odor-active compounds in Mayapan variety aroma, whereas 3-methylbutyl 2-methylpropanoate (FD = 729) and 2-methylpropyl 2-methylbutanoate, hexyl pentanoate and δ-cadinene (FD = 243) were characteristic in Jaguar variety. An intense pungent odor was notorious in Mayapan variety, due mainly to 3,3-dimethylcyclohexanol. On the basis of FD values, sweet and pungent were characteristic notes in Mayapan variety, whereas sweet and fruity notes were predominant in Jaguar variety. This suggests that aroma variability among Habanero pepper varieties might be related to their genotypic diversity. This study involved multiple reactions and reactants, such as Isopentyl hexanoate (cas: 2198-61-0Recommanded Product: 2198-61-0).
Isopentyl hexanoate (cas: 2198-61-0) belongs to esters. Esters are also usually derived from carboxylic acids. It may also be obtained by reaction of acid anhydride or acid halides with alcohols or by the reaction of salts of carboxylic acids with alkyl halides. Many esters have the potential for conformational isomerism, but they tend to adopt an s-cis (or Z) conformation rather than the s-trans (or E) alternative, due to a combination of hyperconjugation and dipole minimization effects. The preference for the Z conformation is influenced by the nature of the substituents and solvent, if present. Lactones with small rings are restricted to the s-trans (i.e. E) conformation due to their cyclic structure.Recommanded Product: 2198-61-0
