3.4. Color
Table 3 summarizes the changes in color properties of the pis- tachios during the storage period. The L* values of the samples increased significantly (P < 0.05) at CP, VP and MAP during the storage. Additionally, the highest L* value was observed at VP sample with the value of 37.5. The a* values of the CP pistachio samples were significantly different from each other. The highest and lowest a* values were detected at CP and MAP samples with values of 28.0 and 23.2, respectively at the end of the storage. Interaction effect of packaging type and storage time was also found significant for the L*, a* and b* value parameters (P < 0.05).
