Treatment: Control, 0.01% sodium nitrite+0.05% sodium ascorbate; treatment 1, 0.3% white kimchi powder+0.5% lemon extract powder; treatment 2, 0.3% white kimchi powder+1.0% lemon extract powder; treatment 3, 0.3% white kimchi powder+0.5% vinegar powder; treatment 4, 0.3% white kimchi powder+1.0% vinegar powder; and treatment 5, 0.3% white kimchi powder+0.5% lemon extract powder+0.5% vinegar powder.
Storage day: All samples were stored at 2°C−3°C for 30 days in the dark until analysis. Measurements were made on 0, 15, and 30 days.
