Optimization of Oil Extraction from Camellia Seeds by Response Surface Methodology

Abstract

Abstract: Serious emulsification occurring during aqueous phase extraction of oil leads to low oil yield. In the present study, we used response surface methodology to optimize the extraction of camellia seed oil for the purpose of maximizing oil yield. A mathematical model that describes oil yield as a function of solvent-to-solid ratio, temperature and extraction time was fitted. The optimal extraction conditions were found to be extraction at 61.56 ℃ for 1.26 h with a solvent-to-solid ratio of 3.13:1 (mL/g). Under the optimal conditions, the predicted oil yield was 98.02%. The results of validation experiments suggested these extraction conditions to be reliable.

Key words: camellia seed oil, extraction process, response surface methodology, mathematical model
