Abstract
In order to extract
lycopene more effectively, this experiment focused on the optimization of
ethanol pretreatment method to study the effects of ethanol treatment on the
extraction rate of lycopene and its antioxidant activity. The test results show
that 2 times ethanol treatment is very effective for improving lycopene yield.
The optimum conditions of ethanol treatment are temperature 50 ℃,
treatment time 1 time 2h, 2 times 2h, solid to liquid ratio is 1:12. The lycopene
yield can be reached 20mg / 100g above.
