Abstract:

【Objective】 The aim of this study is to optimize the better extraction process of β-carotene from the skin residue of Xinjiang Lycium barbarum in order to promote the comprehensive utilization of Xinjiang Lycium barbarum resources.Provides theoretical basis and technical support for the high-value utilization of Lycium barbarum dregs. 【Methods】 Anhydrous ethanol was used as the extraction solvent, and the effects of material-liquid ratio, temperature, time, and the number of extraction times on the extraction amount of β-carotene from the skin dregs of Lycium barbarum were investigated. The extraction process was optimized by Random Centroid Optimization (RCO), and then the better extraction conditions were determined. In addition, the antioxidant capacity of β-carotene against DPPH radicals and ABTS radicals was also determined. 【Results】 The optimized parameters of the best extraction process were: material-liquid ratio 1∶16 g/mL, temperature 48℃, time 41 min, and number of extractions twice. Under these conditions, the extracted amount of β-carotene reached 0.53 mg/g. β-carotene showed good antioxidant ability, and the scavenging rates of DPPH and ABTS radicals were 60.89% and 66.11% at a mass concentration of 1.0 mg/mL, respectively. 【Conclusion】

摘要:

【目的】研究优化新疆枸杞皮渣中β-胡萝卜素的较佳提取工艺,促进新疆枸杞资源的综合利用,为枸杞皮渣的高值化利用提供理论依据和技术支持。【方法】采用无水乙醇作为提取溶剂,考察料液比、温度、时间、提取次数对枸杞皮渣β-胡萝卜素提取量的影响。通过随机质心映射法(Random Centroid Optimization, RCO)优化提取工艺,确定较佳提取条件。并测定β-胡萝卜素对DPPH自由基和ABTS自由基的抗氧化能力。【结果】优化后的最佳提取工艺参数为料液比1∶16 g/mL、温度48℃、时间41 min、提取次数2次。在此条件下,β-胡萝卜素的提取量达到0.53 mg/g。β-胡萝卜素表现出良好的抗氧化能力,在质量浓度为1.0 mg/mL时,对DPPH和ABTS自由基的清除率分别为60.89%和66.11%。【结论】优化了枸杞皮渣中β-胡萝卜素的提取工艺。最佳提取条件为料液比1∶17 mg/mL、温度57℃、时间45 min、提取次数2次,提取量为0.53 μg/g。
