摘要

摘要: 目的:优化油茶饼粕多糖提取工艺,为大规模工业化生产提供参考。方法:以湖南常德地方油茶品种(饼粕)为试材,进行了影响多糖提取得率的10个单因素实验,采用主成分分析选取影响多糖提取得率的4个主要单因素,进行4因素3水平正交实验。结果:得出油茶饼粕多糖提取的最佳工艺参数为:3.0 h酶反应时间、1∶30(g/m L)料液比、2.0 h超声提取时间、85℃提取温度;结合其余六个较优单因素实验条件(6个月贮藏期、90目油茶饼粕粉末、3.0%酶浓度、1000 W超声功率、提取3次、75%乙醇沉淀)进行5次平行验证实验,得到油茶饼粕多糖的实际提取得率为7.12%±0.20%。结论:该工艺操作简单、便捷快速、效率和提取得率高,为今后工业化生产提供了有效的参考标准,为广泛开发油茶饼粕中多糖资源提供了良好的参考价值。

Abstract: Objective: To optimize the extraction process of polysaccharide from Camellia oleifera cake, it provides reference for large-scale industrial production.Method: 10 single factors experiment were carried out on the polysaccharide extraction of oil tea cake from Hunan Changde local Camellia oleifera ( Cake) varieties. Principal component analysis was used to select the 4main single factors of affecting the extraction yield of polysaccharides, and 4 factors and 3 levels orthogonal tests were carried out.Result: The optimum extraction process of polysaccharide from Camellia oleifera cake was obtained: 3.0 h enzyme reaction time, 1∶ 30 ( g/m L) material to liquid ratio, 2.0 h ultrasonic extraction time, 85 ℃ extraction temperature.Combined with the other six optimal single factor experimental conditions ( 6 month storage period, 90 mesh camellia cake powder, 3% enzyme concentration, 1000 W ultrasonic power, 3 times of extraction, 75% ethanol precipitation) , 5 parallel validation experiments were performed.The extraction yield of camellia cake polysaccharide was 7.12% ± 0.20% under this condition.Conclusion: The process is simple to operate, convenient and fast, efficiency and yields are high.It provides an effective reference standard for industrial production in the future, It provides a good reference value for the development of polysaccharide resources in Camellia oleifera cake.
