The effect of different packaging films on storability and qualitative properties of button mushroom (Agaricus bisporus)
Proper packaging and appropriate storage period are important factors affecting safety and quality, reducing waste, saving costs and overall marketing of products such as button mushrooms. This research was conducted to evaluate the effect of packaging film (uncoated, poly vinyl chloride (cellophane), polyethylene 14, 20, 27 and 38 microns, ethylene-absorbing plastic and conventional plastic) and storage time (0, 7, 14 and 21 days) on the storability and qualitative properties of button mushrooms, in Gorgan University of Agricultural Sciences and Natural Resources, during 2015. The obtained results showed that the effect of packaging film, storage time and the interaction of film and time were significant at 1%. Generally, polyethylene 20 microns due to moisture protection of mushrooms (minimum weight loss), high total soluble solids, low titratable acidity, high flavor index and antioxidant capacity, good appearance and marketable quality, acceptable amount of phenolic compounds, flavonoids and vitamin C, was effective packaging technique. According to the obtained results, conventional coating film, polyvinyl chloride did not provide acceptable results. By considering the important qualitative parameters this product can be stored with good quality for 7 to 14 days after harvesting. Generally, regarding to the positive and efficient effects of polyethylene films, this type of coverage can be a great alternative for polyvinyl chloride film.
