Abstract
Edible fresh mushrooms have a limited shelf life; to enhance production, it is necessary to employ effective methods to extend their shelf life. In this study, coating with chitosan in amounts of 1, 1.5, and 2% and conventional polyethylene-based packaging were used alongside novel packaging containing phase change material to preserve button mushrooms. Weight loss percentage, texture, mushroom respiration intensity, browning coefficient, soluble solids percentage, and psychrotrophic bacteria count were evaluated on the day of packaging, third, sixth, ninth, and twelfth days under refrigerated storage conditions. The results were analyzed using MiniTab 16 statistical software. The results showed that the percentage increase in microbial load, browning coefficient, mushroom respiration rate, weight loss, and percentage of soluble solids in mushroom treatments with conventional packaging was higher than that with novel packaging (p≤0.05). In the treatment with a 1.5% chitosan coating, the increase in the microbial population index of the mushroom treatments was lower. As a result, mushrooms coated with 1.5% chitosan and novel packaging containing phase change material were selected as the optimal treatment.
