Upcycling Pomegranate Peel Into Functional Yoghurt: Chemical Profile, Antioxidant Capacity, and Anti–Staphylococcus aureus Activity

Food Safety and Health, EarlyView.
Pomegranate peel extract enhanced the nutritional, physicochemical, and microbiological qualities of yoghurt. It is a rich source of polyphenolic compounds that eliminates Staphylococcus aureus in yoghurt at 0.1% and 0.3% concentrations without altering its pH value. ABSTRACT The use of natural additives, particularly pomegranate peel extract (PPE), to

Structural and Antioxidative Features of Chlorogenic Acid

Croatica Chemica Acta, 2016
This work contributes to the structure clarification of chlorogenic acid (5-O-caffeoylquinic acid, 5CQA) by comparing the experimental and simulated IR, Raman, 1H-NMR, 13C-NMR, and UV-vis spectra. The lowest-energy conformers in the gas-phase and solution were used for all calculations. Very good agreement between all experimental and simulated spectra
