Alyssum homolocarpum seed gum (AHSG) and sodium alginate (SA) were utilized as wall materials for the microencapsulation of Echinacea purpurea extract via spray drying. Furthermore, effect of microcapsules on the oxidative stability of camelina oil was assessed over a 30-day storage period. The results showed that with an increase in AHSG concentration, the particle size, polydispersity index, and zeta potential of emulsions decreased, while their viscosity, and stability increased.

The kinetics of changes in jujube honey samples heated at various temperatures (45, 55 and 65 °C) over 10 days were studied. Increasing treatment temperature and time caused an increase in all three parameters including, antioxidant activity, BPF and TPC.
