Abstract:
Peanut oil, a vegetable oil extracted from Arachis hypogaea L., is a valuable carrier for encapsulation processes. This study assesses the quality of peanut oil from three cultivars (GG-20, GJG-22, GJG-32) in Gujarat, India, with a focus on its suitability for encapsulation. Physical properties, viscosity and specific gravity were similar. Peroxide values (4.90-5.70 meq/kg oil) revealed acceptable oxidative stability which is crucial for preserving encapsulated compounds. Varying iodine values (74.45-82.49 mg/100g) and saponification values (176.90-184.10 mg KOH/g) offer formulation flexibility. Fatty acid analysis showed high unsaturated fatty acid content (80.09-84.05%), enhancing stability and resistance to oxidation, favouring encapsulation. GJG-32, with a significantly higher polyunsaturated fatty acid (PUFA) content (38.17%), faces potential oxidative degradation. Its lower MUFA/PUFA (1.10) and UFA/SFA (4.02) ratios indicated higher susceptibility to oxidative degradation. Thus, from the selected cultivars, GJG-32 peanut oil exhibits promise as an encapsulation carrier.
