Isolation and isomerization of lycopene from

isolation and isomerization of lycopene from Lycopene undergo degradation via isomerization and oxidation under different heating exposures but at the same time, heating can enhance the extractability of lycopene from the tomato matrix light as discussed previously heat and light are the two major factors which highly affect the food quality in processing and material handling procedure.

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.
