Effects of storage time and quality in white button mushroom (Agaricus bisporus) on edible coating materials

In this study, it was investigated that effects of edible coating materials and UV-C irradiation under modified atmosphere conditions on postharvest physiology of White button mushroom (Agaricus bisporus) which is consumed gladly in the world and Turkey. The mushrooms which are harvested same maturity were coated with edible coating materials (Agar or egg white protein) and they were stored under the conditions of 90-95 % relative humidity at +4 °C during 20 days. Weight loss, color (L*, a*, b* C* and Hue), in - package gas components (O2, CO2 and N2), protein, total phenolic content, total antioxidant activity, catalase, polyphenoloxidate (PPO) respiration rate and external ethylene content were determined at harvest and 5 days intervals following harvest. When examined all parameters were taken into consideration in the study, it was found that edible coating material which gives the best result is agar in white button mushroom (Agaricus bisporus) which was storaged +4 °C and 90-95 % relative humidity conditions during 20 days.
