These are also present as the active component in photosynthetic organisms and majorly their teleology is to help during important functions like photosynthesis and to provide defense to the host organisms from the overabundant light damage.

The key factors influencing lycopene degradation and isomerization, such as ingredients and intensity of thermal treatments, are also discussed. Maximum C vitamin loss occurred in 15 minutes of heating at 100 °C, and when the processing temperature drops, the additional C vitamin loss rate becomes smaller. J Sci Food Agric 90:1597–1604, 3.

Tomato processing Tomato is the most widely spread vegetable on our planet and it is not only the foundation of Mediterranean food culture, but it also serves as a major supplement to the cuisines of the world. In products packaged in low oxygen barrier material and kept in cardboard outer packaging, loss also subsequently continued. Lavelli V, Torresani MC (2011) Modelling, copene-rich by-products of tomato processing. Our hypothesis that energy input can cause isomerization lead us to study the increase in cis isomer content on using HHP processing technology.
