摘要:

优化高压微波提取葡萄籽中原花青素的最佳工艺参数与其他提取方法进行对比。结果表明,高压微波提取原花青素的最佳工艺参数为乙醇体积分数74%、液料比30:1、微波功率900W、提取时间120s、提取压力0.8MPa,此时得率为4.195%;与其他提取方法相比,高压微波提取时间短、得率高。

Abstract:

High pressure microwave-assisted extraction (HPME) was applied to extract procyanidins from grape seeds. The effects of ethanol concentration, material/liquid ratio, microwave power, extraction time and pressure on yield of procyanidins were investigated by single-factor method. Subsequently, a three-factor, three-level Box-Behnken experimental design combining with response surface modeling (RSM) was employed for maximizing the yield of procyanidins. A maximum yield of procyanidins of 4.195% was obtained by extraction for 120 s at a microwave power of 900 W and 0.8 MPa using 74% ethanol as the extraction solvent. HPME had many advantages over other extraction techniques, including time saving and high extraction efficiency.

Key words: high pressure microwave extraction (HPME), procyanidins (PC), Box-Behnken experimental design
