Capsaicinoid profile of soft-flesh Capsicum spp. genotypes according to the purée production method

Abstract

Summary Capsaicin and dihydrocapsaicin concentration was evaluated using the HPLC method in the whole fruit, pericarp, and purée obtained by rubbing fruit through a strainer, purée obtained by fruit expressing, and in the waste following the two above processes. The highest content of each compound was noted in purée and the lowest one in pericarp and waste. Concentration of capsaicin was higher than concentration of dihydrocapsaicin in all of the analysed material. Reciprocal relations between contents of two compounds ranged from 1.4 to 5.3. Capsaicinoid contents in purée obtained by rubbing plus in the waste of the process and in the expressed purée plus the waste of the process were highly similar. Capsaicin and dihydrocapsaicin contents in purée obtained as a result of mechanical separation of soft tissue from the inedible fruit parts was significantly higher than in pericarp and stable, regardless of the processing method.
