摘要： This study aimed to improve lycopene stability and bioavailability in food products. Lycopene, a potent antioxidant, often has poor stability and undesirable organoleptic properties. Therefore, the impact of basil seed gum (BSG) concentration and spray drying inlet temperature (IT) on the physicochemical, bioaccessibility, and antioxidant properties of encapsulated lycopene emulsion (ENL) was investigated using Central Composite Design (CCD)-Response Surface Methodology (RSM). Optimal encapsulation conditions were IT = 141.96 degrees C and BSG = 19.507 %. The ENLs had an average particle size of 147.56 nm, a polydispersity index (PI) of 0.263, and a zeta potential of -21.37 mV, indicating good colloidal stability. Antioxidant activity varied slightly during the four weeks of storage (a 9.65 % increase followed by a 13.6 % decrease), but it remained stable overall. Incorporating ENL into mayonnaise significantly reduced the acid value (2.78 mg KOH/g), the anisidine index (12.43), the peroxide value (7.13 meq/kg), and the TBARS index (0.534), and improved color parameters, reducing brightness (79.94) and whiteness (70.64) while masking lycopene's strong yellow and red hues. This study highlights BSG-encapsulated lycopene's potential to improve oxidative stability and sensory properties, offering a natural and effective method to enhance lycopene stability, bioavailability, and sensory acceptance in various food applications.
