Abstract:

Pepper oleoresin was extracted from black pepper by reflux condensation method. The effects of solvent type,
extraction time, refluxing temperature and material-liquid ratio on extraction rate of pepper oleoresin were studied. The
results of response surface analysis showed that the optimal extraction conditions were as followed: ethanol as extraction
solvent, extraction time of 5.22 h, refluxing temperature of 79.4 ℃, and material-liquid ratio of 1:17.2 (g/mL). Under the
optimal extraction conditions, the extraction rate of pepper oleoresin was up to 11.0%.

Key words: black pepper oleoresin, extraction, response surface methodology
