Changes in headspace oxygen content (A), CDA (B), and p-AV (C) in corn oil containing chitosan or collagen loaded with α-tocopherol at 60 °C. Different capital or small letters are significantly different at 0.05 with α-tocopherol added samples or without α-tocopherol added samples, respectively. ‘Control’, ‘Chitosan’, and ‘Collagen’ were oil samples without addition of α-tocopherol nor carriers, with added chitosan gel, and with added collagen mesh structure, respectively. ‘Control + T’, ‘Chitosan + T’, and ‘Collagen + T’ were oil samples with addition of α-tocopherol, with α-tocopherol loaded chitosan gel, and with α-tocopherol loaded collagen mesh structure, respectively
