Spray-dried yellow cashew juice ingredients produced under different inlet temperatures (140 and 150 °C) and gum arabic (GA) addition ratios (15% and 25% w/v) were evaluated for their physicochemical and phytochemical attributes and storage stability for 56 days. All spray-dried cashew juice particles showed high solids recovery (&gt;70%) and solubility (&gt;90%), low water activity (&lt;0.3), and low hygroscopicity (&lt;10%). Spray-dried particles prepared with 15% w/v GA showed spherical shapes with a semi-crystalline structure and higher ascorbic acid concentration (&gt;650 mg 100 g−1) and total phenolic content (&gt;330 mg GAE 100 g−1). During storage, spray-dried cashew juice particles maintained their water activity levels within the microbiologically safe range and retained high solubility, in addition to high ascorbic (&gt;68%) and phenolic (&gt;55%) acid retention. Overall, we showed that spray-drying cashew juice is a feasible strategy to upcycle abundant and undervalued cashew juice into stable, phytochemical-rich ingredients for multiple applications.
