Coating of mushrooms by Iranian Endemic Gum (Loucost Gum): Evaluating Barrier Properties and Physico Mechanical Effects.

Mushroom is perishable and has a relative short shelf life. In this research, fresh mushrooms were treated with aqueous solutions of 0% (Control), 0.5% and 1.0% of Loucost gum, glycerol (0.5% and 1%) and sodium borate (0 and 2%). all samples were enclosed in plastic with nylon and then stored at 25 ± 1 ◦C and kept at 3- 4 ◦C with 95% relative humidity for 20 days. The results showed that of 0.5% gum +0.5 glycerol+2% sodium borat in both temperature were effective in preserving Texture and visual appearance, delayed changes in the peel colour and the increase of polyphenol oxidase (PPO) and peroxidase activity (POD). The results indicated that the use of Locust gum effectively retained postharvest quality and extended shelf life of mushrooms
