Fresh Welsh onions are widely used in food formulations due to their distinctive flavor and biological properties, but high perishability limits industrial applications. In this study, powdered onion leaf juices were obtained through freeze-drying, with without maltodextrin (MD) gum arabic (GA) as carrier agents. MD was chosen for its solubility neutral taste, while GA selected ability improve powder stability dispersibility. Powders using a completely randomized design evaluate the effects of five MD:GA ratios (0:100, 25:75, 50:50, 75:25, 100:0) on physicochemical technological properties. The addition carriers enabled formation fine, homogeneous powders higher water solubility. All exhibited low activity (<0.4) moisture content (<7%). Polyphenol ranged from 2.60 3.53 mg GAE/g dry matter, recovery percentage (94–96%). DPPH• scavenging about 0.55 matter all Fourier-transform infrared (FTIR) analysis confirmed presence characteristic bands both agents juice, thermogravimetric (TGA) revealed enhanced thermal Flowability tests showed that blends significantly improved handling.
