Lycopene isomerization during processing would provide a measure of the potential isolation and quantification of lycopene 11 material and methods plant material. Lycopene is a pigment principally responsible for the characteristic deep-red color of ripe tomato fruitsit has a natural source of antioxidants, has attracted attentions due to its biological and physicochemical properties. Lycopene has a large number of geometric isomers caused by e/z isomerization at arbitrary sites within the 11 conjugated double bonds, offering varying characteristics related to features such as antioxidant capacity and bioavailability. Isomerism | isomerization | organic chemistry | class 12 chemistry subject notes lectures top most best online video lectures preparations notes for class 12.
Tomato products can cause oxidation and/or isomerization of lycopene, and thus, increase or decrease the active lycopene content hence, investigation of the effects of different cooking.
