摘要: 论文在单因素试验的基础上,采用响应曲面分析法响应面法,研究了乙醇体积分数、液料比、超声波功率和超声波处理时间对莲房中原花青素莲房原花青素提取率提取得率的影响,通过建立超声波辅助提取莲房中原花青素莲房原花青素的多元回归模型,优化了莲房中原花青素莲房原花青素的提取工艺参数。结果表明,液料比对莲房中原花青素莲房原花青素提取率提取得率的影响最大,其次是乙醇体积分数和超声波功率,超声处理时间的对提取率的影响相对较小超声处理时间的对提取得率的影响相对较小。在乙醇体积分数为45%、液料比21:1mL/g(mL/g)、超声波功率700W、超声波处理15min时,莲房原花青素提取率提取得率最大,为6.81%,与模型理论预测值相近,说明该模型回归性良好,试验的拟合程度高,可以用于莲房中原花青素莲房原花青素提取率提取得率的预测。试验结果该研究可为莲房中原花青素作为天然食品色素和抗氧化剂的应用产业化生产提供一定的科学数据科学数据。

Abstract: The single-factor test and response surface methodology (RSM) were adopted to study the effects of ethanol?concentration, liquid-solid?ratio, ultrasonic power and ultrasonic treatment time on the extraction yieldcapacity of proanthocyanidin from lotus seed pot (LSP). The multiple regression model of ultrasonic-assisted extraction of LSP was established to optimize the extraction technology parameters. The results indicated that the liquid-solid?ratio had the most significant impact on the extraction capacityyield of LSP, followed by the ethanol?concentration and ultrasonic power, while the impact of ultrasonic treatment time was relatively low. When the ethanol concentration was 45 %, liquid-solid?ratio was 21:1 mL/g(mL/g), ultrasonic treating for 15 min at 700 W, the extraction capacityyield of LSP could reach the maximum value (6.81 %), which was close to the model theoretical predictive yield. It proved that the recursion of the model was significant and could be applied in the prediction of extraction capacityyield of LSP. The test resultsstudy could provide scientific data to industrial productionapplication of LSP as a food pigment and natural antioxidant.
