Extraction of pure lycopene from industrial tomato by‐products in water using a new high‐pressure process

Abstract: BACKGROUND: Lycopene, a precursor of β-carotene with a well-known antioxidant activity, contained in many natural products such as tomato (Lycopersicon esculentum Mill.), watermelon, red pepper and papaya, is usually recovered from natural vegetal sources using organic solvents and a purification step. In this paper an innovative process for the extraction of pure lycopene from tomato waste in water that uses the Naviglio  extractor and water as extracting phase is presented.

“…The initial TAC of T-R1/R2 smoothies obtained by FRAP, ABTS, and DPPH were 488±5/659±46, 527 ± 4 2 / 6 3 7 ± 4 0 , a n d 2 3 3 ± 2 4 / 2 8 7 ± 2 4 m g Tr o l o x equivalents kg −1 fw, respectively. The low TAC found by DPPH method may be explained since the wavelength for peak absorbance of lycopene (Naviglio et al 2008), the main carotenoid of tomatoes, is close to that used for the DPPH method. This may induce the observed reduced TAC by DPPH.…”

“…The determination of lycopene was performed by reading the absorbance at 503 nm and by using the Lambert Beer equation, with the molar extinction coefficient ε = 152,989 L/mol·cm for lycopene dissolved in chloroform (Naviglio et al, 2008). Results were expressed as mg per 100 g fresh weight (FW).…”

“…The extract was then analyzed for its lycopene content using UV-Vis spectroscopy technique (Make: Varian-Carry-50). The remaining extract, was taken for measuring the lycopene content using UV-Vis spectrophotometer at 503 nm [11][12][13]. The data were recorded and the lycopene content (mg/100 g) was calculated using the following formula: …”
