The Research of Lycopene Extraction Method at Determination
Determination of lyeopene By UV - visible spectrophotometry. Investigated in the extraction time, the extraction times, the extraction agent select affect lycopene measuring effect. The results showed that: the impact ketchup lycopene extract factors order was: solid-liquid ratio〉 mixture agent〉 extract〉 extraction times; the optimal combination of measuring ketchup lycopene extract was ethyl acetate + ethanol (9+1), solid and liquid ratio of 1:2, the extraction time of 30 min, extraction times of 1.
