Optimization of Aqueous Extraction Process for Camellia Seed Oil by Response Surface Methodology

Abstract

Abstract: Response surface methodology (RSM) was used to optimize the aqueous extraction of camellia seed oil. Quality characteristics of the resultant product were analyzed. The optimum conditions for the extraction of camellia seed oil were determined as follows: camellia seed kernels were dried at 150 ℃, crushed, and added with hot water at a solvent/solid ratio of 3.8:1 (mL/g) for oil extraction at 80.2 ℃, natural pH for 3.4 h. Under these conditions, an oil yield of 69.1% was obtained. All tested physiochemical indexes of the oil obtained met the national standards for grade 2 camellia seed oil. Therefore, aqueous extraction is applicable for the extraction of camellia seed oil.

Key words: camellia seed oil, aqueous extraction method, quality analysis
