Lycopene Content of Tomato Products: Its Stability, Bioavailability and In Vivo Antioxidant Properties.

摘要: Lycopene is a bioactive carotenoid present in many fruits and vegetables. Tomatoes constitute the major dietary source of lycopene. Recent evidence shows lycopene to be associated with several health benefits. However, very little information available about stability its bioavailability. Because tomatoes undergo extensive processing storage before consumption, study was conducted evaluate stability, isomeric form, bioavailability, vivo antioxidant properties Total isomers were measured by spectrophotometry high-performance liquid chromatography, respectively. content remained unchanged during multistep operations for production juice or paste stable up 12 months at ambient temperature. Moreover, subjecting tomato cooking temperatures presence corn oil resulted formation cis which considered more bioavailable. absorbed readily from sources. Serum lipid low-density lipoprotein oxidation significantly reduced after consumption products containing
