摘要
为综合利用茄子皮,本研究以茄子皮为原料提取花青素,并优化其提取工艺。以花青素得率为指标,通过单因素和正交试验得出茄子皮中花青素的最佳提取工艺。研究结果表明,以70%乙醇为提取溶剂,1∶20(W/V)料液比,在60℃提取90 min,提取3次时,茄子皮中花青素提取率最高,得率为6.56%。该方法简单、快捷,是提取茄子皮中花青素的有效方法。
For comprehensive utilization eggplant peel, anthocyanin was extracted from eggplant peel and the extrac- tion technology was optimized. Organic solvent extraction methods were used to extract anthocyanin in peel of eggplant. The best conditions of extracting the anthocyanin from eggplant peel were obtained through single factor and orthogonal ex- periment, which were 70% ethanol, extracting temperature 60 ℃, extracting time 90 min, and extracting times 3. Under the optimum technological conditions, the content of the anthocyanin in the produce was 6. 56%. The data was reliable and reasonable.
