Optimization of the Production Process of Bishop’s Crown Pepper (Capsicum baccatum var.) Hydroalcoholic Extract

Abstract

This study developed and evaluated the efficiency of methods to produce hydroalcoholic extract of Bishop’s Crown pepper. Analyses were conducted to investigate the effects of independent variables (ethanol concentration of the extracting solution and resting time) over the dependent variables (percent yield, acidity, carotenoids, phenolic compounds, anthocyanin content and vitamin C). The interactions between the variables were studied through seven factorial experiments. Percent yield (Y%), carotenoids, phenolic compounds and vitamin C were the most satisfactory responses found in this research. The ethanol concentration of the extracting solution (ES) presented significant effect in the Y%, showing better results for extracts produced with a 55%-ethanol ES, while carotenoids, phenolic compounds and vitamin C displayed significant differences according to the ethanol concentration, being these substances found in higher concentrations in extracts produced with the use of an 85%-ethanol ES. Therefore, the higher the ES ethanol concentration, higher is the retention of the bioactive compounds.

Genetic Regulation, Environmental Cues, and Extraction Methods for Higher Yield of Secondary Metabolites in Capsicum

“…Extractable color in the range of 36.9–144.2 ASTA color units and capsaicin in the range of 999–47,814 SHU, respectively, were extracted using solvent extraction in six C. annuum cultivars . Higher concentrations of ethanol (up to 85%) were able to extract higher % yield of carotenoids, vitamin C, and phenolic compounds from C. baccatum (Bishop’s Crown Pepper) . Solvent extraction of carotenoids with 60% acetone and 40% petroleum ether provided a yield of 42 mg kg –1 DM from chili byproducts .…”

“…216 Pepper). 217 Solvent extraction of carotenoids with 60% acetone and 40% petroleum ether provided a yield of 42 mg kg −1 DM from chili byproducts. 218 In short, lower polarity and viscosity of the solvent and higher solvent:solid ratio facilitates the maximum yield of the capsaicinoids.…”
