Abstract

The optimum process of extracting capsaicin,the bioactive component in paprika( Capsicum annuum L.) was studied.The optimum extraction process was optimized with orthogonal test.Experiments were made by using L9(34) orthogonal design with extractive yield of capsaicin as the index,investigating the influence of ethanol concentration,temperature,extracting time and the ratio of solid to liquid.Optimum extraction conditions were determined as follows:temperature 70℃,time 0.5 h,70% EtOH as extracting solvent,stock ratio 1:10(mass:volume),extracting for three times.
- Capsicum annuum L.,
- capsaicin,
- orthogonal test
