Optimization of Ultrasound-assisted Extraction of Oil from Camellia (Camellia Oleifera Abel) Seed

摘要

Camellia oil is the main component of the camellia seed and has many beneficial functions to human health. An investigation into ultrasound- assisted extraction was conducted for the oil extraction from camellia seed. The optimized condition of extraction parameters obtained with the response surface methodology (RSM) at a four-variable, three-level experiment Box-Behnken design (BBD), was as follows: liquid-solid ratio, 5mL/g;ultrasonic power, 155W;ultrasonic treatment time,31 min;;and ultrasonic treatment temperature, 55°C, under these conditions, the oil yeild was 44.55%. GC-MS analysis showed that the content of unsaturated fatty acid in camellia oil was up to 84.47% and the content of oleic acid was over 76.15%.
