Delaying the postharvest quality modifications of Cantharellus cibarius mushroom by applying citric acid and modified atmosphere packaging

This study aimed to assess the effects of different treatments [citric acid (CA), perforated and unperforated, packaging (17 and 23 mu film thickness)] on weight loss, respiration and decay rate, color, bioactive compounds, dry matter, ash and protein of Cantharellus cibarius mushroom during the cold storage [at 0 +/- 0.5 degrees C and 90 +/- 5% relative humidity (RH) for 12 days (d)]. Modified atmosphere packaging (MAP) significantly reduced weight loss and decay compared to control. With the progress of the storage period, the significant increases were observed in protein, ash, dry matter, vitamin C, total phenolic and antioxidant activity. At the end of storage, citric acid+23 mu m thick non-perforated low-density polyethylene [LDPE (CANP23)] treatment for the highest protein; control and distilled water+23 mu m thick non-perforated LDPE (NP23) for the highest vitamin C; citric acid+17 mu m thick non-perforated LDPE (CAP17) for the highest total phenolics; NP23 for the highest antioxidant activity was determined. As a result, it was revealed that the weight loss and decay rate of Cantharellus cibarius can be significantly reduced with MAP and more caution should be taken regarding the citric acid (CA) application and the studies should be conducted to find the appropriate dose.
