Studies On Extraction Technology And Stability Of Lycopene

The paper used tomato sauce which was producted in XinJiang as raw material to study extraction efficiency of lycopene by microwave irradiation, mix extraction and enzyme treatment. By the experiment, we determined the optimum extracting solvent and technongical conditions. By studying the method of removing solvent in tomato oleoresin, efficiency of removing solvent was determined by gas chromatography(GC), we determined high vacuum conditions were the safety and efficiency method of removing solvent. We studied the way of purification of lycopene,determined the suitable solvent of crystallize, and regarded crystallization and recrystallization as ideal method which got high purification lycopene. We used Drosophila Melanag as objective of research to study antiaging effect of lycopene, the results showed that lycopene can obviously prolong Drosophila Melanag life span. In this study, ultraviolet spectrum, thin layer chromatography(TLC) and high performance liquid chromatography(HPLC) were used to identify the qualitative analysis and quantitative analysis of crude pigment of lycopene and pure pigment of lycopene, and studied the stability of lycopene in different conditions. finding out all kinds of facts which affect the stability of lycopene, and providing reference and evidence for protecting tincture and safety store of lycopene product.
