SC-CO2 extract of a polyherbal mix of 1:1:2 tulsi leaves, bay leaves and cardamom seeds having appreciable antioxidant potency was encapsulated using spray drying technology. Maltodextrin and gum arabic (60:40) were used as wall materials at an inlet temperature of 140�?°C to obtain an encapsulated powder. The microencapsulation efficiencies of the bioactive compounds were found to be 71% and 56% for eugenol and 1, 8-cineole, respectively and their surface binding was within the range of 2-5%. From the scanning electron microscopy photographs of the encapsulated powder, it was observed that the particles have smooth rounded morphology with size ranging from 3 to 25 mm. The powder had appreciable antioxidant activity, phenolic content, reducing power and anti-inflammatory potency. The encapsulated SC-CO2 extract of the polyherbal mix was evaluated for its possible usage as a natural antioxidant in soybean oil. Non-encapsulated and encapsulated SC-CO2 polyherbal extracts were administered individually into soybean oil samples to act as natural antioxidants. Two sets of oil samples were administered with the widely used commercial antioxidants- BHT and TBHQ. The shelf life and frying stability of soybean oil were ascertained using potato wedges as the model fried food. 30-day storage and frying stability studies of soybean oil samples, administered individually with the encapsulated and non-encapsulated extracts and commercial antioxidants TBHQ and BHT, established that the encapsulated polyherbal SC-CO2 extract had the best antioxidant efficacy. This encapsulate allows controlled release of the antioxidant and is therefore advocated as a promising â�?�?greenâ�?�? antioxidant for soybean oil.
