3.1. Color characteristics during cold storage
The color characteristics (L*, chroma, hue angle) linearly decreased during the storage period ( Fig. 1). The L* value decreased from 28.02 to 21.84 in the control, from 30.45 to 21.49 with 100 mg L−1 AVG and from 30.51 to 21.99 with 200 mg L−1 AVG. In addition, the decrease in hue angle during storage for 100 mg L−1AVG (from 32.37 to 23.21) was higher compared with the decrease in the control and 200 mg L−1 AVG treatments. The highest C* value (14.21) at the end of storage was obtained with the 100 mg L−1 AVG treatment, and the lowest value (9.15) was observed in the control.
