Study on the Best Hexane Extraction Process for Hehuang Safflower Seed Oil with Orthogonal Test

ZHANG Gong et al(Department of Chemistry and Life Sciences,Qinghai University for Nationalities,Xining,Qinghai 810007)  
[Objective]The aim was to optimize and make sure the best extraction process of Hehuang safflower seed oil by hexane.[Method]Taking Hehuang safflower seed oil rate as the index,four factors of extraction temperature,reflux time,extraction times,liquid-solid ratio were studied by orthogonal experiment.[Result]The results indicated that the influencing factors to the oil rate are CADB.The factor B was taken as the error to do the variance analysis,the conclusion indicated extraction temperature and extraction time have significant influence to the oil rate of Hehuang safflower seed oil.[Conclusion]Though considering oil rate and the factual situation,the optimum process is A3B2C3D3,namely extraction temperature 65 ℃,reflux time 2 h,extraction times 3,liquid-solid ratio 3∶1.
