Effect of caseinophosphopeptides added to fruit beverages upon ferritin synthesis in Caco-2 cells
2010
Ferritin synthesis was evaluated in iron sulphate solutions and in fruit beverages supplemented with iron, with/without zinc in the presence of caseinophosphopeptides (CPPs), based on a system combining simulated gastrointestinal digestion and the Caco-2 cell model. In iron sulphate solutions with/without zinc, the addition of CPPs had no effect upon ferritin synthesis. When CPPs were added to the bioaccessible fraction of fruit beverages supplemented with iron, ferritin synthesis increased in the same proportion as with the addition of milk. The addition of zinc to fruit beverages supplemented with iron and to iron sulphate solutions decreased ferritin synthesis. Nevertheless, in fruit bev…
Iron and zinc bioavailability in Caco-2 cells: Influence of caseinophosphopeptides
2013
Abstract A study has been made of the influence of two pools of caseinophosphopeptides (CPPs) obtained from α s - and β-casein (CN) fractions, and of three specific CPPs (β-CN(1–25)4P, α s1 -CN(64–74)4P and α s2 -CN(1–19)4P), on iron bioavailability (ferritin synthesis) and zinc bioavailability (retention, transport and uptake of zinc) in Caco-2 cells. α-CPP and β-CPP pools did not improve ferritin synthesis, but the three specific CPPs showed an increase in ferritin synthesis in Caco-2 cells versus iron sulphate, β-CN(1–25)4P being the most effective. In relation to zinc bioavailability, α-CPPs, β-CPPs, α s1 -CN(64–74)4P and β-CN(1–25)4P increased zinc uptake. However, this increase was of…
