Abstract
Alginate-chitosan (Alg-CH) coated multiple water-in-oil-in-water (W/O/W) nanoemulsion loaded with sesamol and retinol was hypothesized to enhance the oxidative stability of margarine. Total phenol content (TPC), antioxidant activity, acid value (AV), peroxide value (PV), para-anisidine value (pAV), induction period (IP), and residual values of sesamol and retinol by HPLC were determined for 90 days. Margarine with tert-butylhydroquinone (TBHQ) (T3) had the higher TPC and antioxidant activity (8.05 mg gallic acid equivalent (GAE)/g), 53.1 %) than T1 (nanoemulsion, 7.39 mg GAE/g, 38.95 %), T2 (free-sesamol and -retinol, 6.98 mg GAE/g, 31.07 %), and T4 (no antioxidant, 6.46 mg GAE/g, and 14.45 %) while T1 had higher antioxidant activity and TPC than T2 and T4 after 90 days. On day 90, the highest residual values of sesamol (200.10 mg/100 g) and retinol (118.09 μg/100 g) obtained for T1. Overall, T1 contributed to the prolonged oxidative stability of margarine, potentially offering an alternative to synthetic antioxidants.
期刊介绍:
Food Chemistry: X, one of three Open Access companion journals to Food Chemistry, follows the same aims, scope, and peer-review process. It focuses on papers advancing food and biochemistry or analytical methods, prioritizing research novelty. Manuscript evaluation considers novelty, scientific rigor, field advancement, and reader interest. Excluded are studies on food molecular sciences or disease cure/prevention. Topics include food component chemistry, bioactives, processing effects, additives, contaminants, and analytical methods. The journal welcome Analytical Papers addressing food microbiology, sensory aspects, and more, emphasizing new methods with robust validation and applicability to diverse foods or regions.
