Enriched (Z)-lycopene in Tomato Extract via Co-Extraction of Tomatoes and Foodstuffs Containing Z-isomerization-accelerating Compounds

Abstract: The aim of this study was to promote the Z-isomerization of lycopene in its extraction process from tomato pulp by adding foodstuffs containing Z-isomerization-accelerating compounds. The addition of onion, broccoli, mustard, makonbu (Saccharina japonica), or shiitake mushroom (Lentinus edodes) to the ethyl acetate extraction process significantly accelerated the Z-isomerization of lycopene. For example, when lycopene was extracted from tomato pulp at 70 °C without foodstuffs, the total Z-isomer ratio of lycop… Show more

“…According to estimations, all-E-lycopene contains 80 percent to 97 percent lycopene in tomato fruit. However, Z-isoforms account for more than half of the lycopene present in human blood and tissues [43,44] (Figure 2). Millardet identified lycopene in 1876 and named it as 'soanorubin'; later on, it was named lycopene and it was purified [45].…”

“…An interesting work was undertaken by Honda et al (2021), where coextraction was performed with the objective of altering both the structure and composition of the bioactives. Tomato pulp was coextracted with broccoli, mustard, onion, makonbu ( Saccharina japonica ), or shiitake mushroom ( Lentinus edodes ) to promote the Z‐isomerization of lycopene.…”

“…Isothiocyanates (isothiocyanate group) have powerful electrophilicity, and their properties accordingly enhance carotenoid E/Z-isomerization (1-3) . The possible isomerization mechanism of carotenoids by polysulfides (RS-SR) is as follows 42,65,66) :…”
