Influences of freeze‐ and spray‐drying vs. encapsulation with soy and whey proteins on gastrointestinal stability and antioxidant activity of Mediterranean aromatic herbs

Summary The aim of the present research was to study the chemical profile of volatile and non‐volatile compounds in freeze‐ and spray‐dried oregano, thyme, sage, and rosemary as well as to study the gastrointestinal stability and the biological activity of the samples after encapsulation using two proteins (soy and whey). Chemical analysis was performed by HS‐SPME/GC‐MS and HPLC‐PDA techniques. The antioxidant activity (FRAP, DPPH and ORAC...
