千金子制霜新工艺的研究

Frost-like powder processing of Semen Euphorbiae

目的:优选千金子最佳制霜工艺。方法:利用新研制的制霜设备,采用正交试验法,选择种仁前处理方式、加热温度和加热时间为三个因素,以千金子霜含油量及主要泻下成分续随二萜酯和千金二萜醇二乙酸苯甲酸酯含量为指标,综合评价其制霜工艺。结果:千金子最佳制霜工艺为:种仁微炒后粉碎成泥状(粒度为40～60目),于55℃加热30min,出油率控制在51%～53%(g/g),出霜率控制在45%～47%。结论:加热温度对千金子霜含油量及主要泻下成分含量有显著影响,种仁前处理方式和加热时间对千金子霜含油量及主要泻下成分影响不明显。

AIM： To optimize the best technique of making Semen Euphorbiae into frost-like powder. METHODS： Machine was developed equipped with temperature and pressure control. Pretreatment of Semen Euphorbiae, heating temperature and time were selected as factors,fat oil content,euphorbiasteroid and lathyrol diadetate benzozte as main levels,to evaluate the processing. RESULTS： The experiment showed that seeds of Semen Euphorbia were directly broken into powder and heated at 55 °C for 30 min. The oil productivity ranged from 51% to 53% . CONCLUSION： The heating temperature has an influence on fat oil and laxative constitutents＇ content, whereas pretreatment of seed and heating time lack the relationship to.
