摘 要: | [目的]探索提取菊芋花色素的最佳条件。[方法]针对不同条件下菊芋花色素的提取进行了单因素和正交试验,对单因素试验数据进行灰色关联度分析,并利用神经网络预测正交试验并和试验值比较。[结果]菊芋花色素的最佳提取条件为温度60℃,料液比1∶18 g/m L,浸提时间5.0 h,其中浸提温度对提取花色素的影响最大,料液比次之,浸提时间对浸提效果的影响最小;同时提出了减少试验工作量的方法。[结论]该研究可为菊芋花色素的提取提供科学依据。

Abstract: | Objective] The aim was to explore the optimal conditions for extracting pigment from Helianthus tuberosus flower.[ Method] Sin-gle factor and orthogonal test was conducted on extraction of Helianthus tu berosus flower pigment under different conditions.Grey relational de-gree analysis was conducted on data of single factor test.Orthogonal test was predicted by neural network and was compared with trial value. [Result] The optimal conditions were obtained as follows:temperature 60 ℃, solid-liquid ratio 1∶18 g/mL, extraction time 5.0 h.As for in-fluence degree, temperature was the most influential on pigment extraction, solid-liquid ratio took the second place, followed by extraction time.Method for reducing the amount of work was proposed.[Conclusion] The study can provide scientific basis for extraction of Helianthus tuberosus flower pigment. |
