🌿 New FEEDACTIV publication alert!
Our latest study, published in Food Science & Nutrition, explores how plant-derived essential oils — from garlic, thyme, conehead thyme, rosemary, and eucalyptus — can serve as sustainable alternatives to conventional antibiotics in aquaculture.
Antimicrobial resistance is a growing concern in fish farming, and nature may hold the answer. Our team profiled the chemical composition and bioactivity of five essential oils (EOs), revealing strong antimicrobial performance — in some cases matching or even outperforming conventional antibiotics like gentamicin — alongside notable antioxidant and antifungal properties.
But essential oils are volatile and chemically unstable, making them difficult to incorporate into fish feed. To overcome this, we developed spray-dried microcapsules using maltodextrin and starch carriers, achieving encapsulation efficiencies of up to 71% while preserving the oils' bioactivity and improving handling stability.
These findings bring us one step closer to effective, natural feed additives for healthier and more sustainable aquaculture practices.
