dc.description.abstractThe present investigation was carried out on "Effect of edible coatings and packaging method on shelf life of button mushroom (Agarius bisporus)". Three edible coating of three concentrations each were selected. Whey protein of 5, 10 and 15 per cent concentration levels; carboxy mehyl cellulose 1, 1.5 and 2 per cent concentration level and guar gum of 0.5, 1 and 1.5 per cent concentration levels. Coating was applied on mushrooms by dipping method for I min. then all coated and uncoated mushrooms were packed in four packaging methods open polyethylene bag; polyethylene bag sealed; vacuum packaging; nitrogen filled packaging under ambient condition. The quality of mushroom fruits was observed in terms of Physiological weight loss, firmness, Total Soluble Solids, acidity and decay loss. Mushrooms coated with whey protein of 5% concentration and stored in vacuum packaging and polyethylene bag stored in better condition upto second day. Physiological weight loss, firmness, TSS, acidity - 115 - and decay loss were respectively (3.77%, 9.87kg/CM2, 7.2oBrix, 0.49%, 38.33%) upto second day of storage. Mushrooms coated with CMC of 1% concentration and packed in vacuum packaging and polyethylene bag performed better upto third day. Physiological weight loss, firmness, TSS, acidity and decay loss were respectively (3.53%, 7.23kg/cm2, 6.00 ºBrix, 0.59% , 46.19%) upto third day of storage. Guar gum coated mushroom spoiled after first day of storage. Fresh mushrooms i.e. without any coating stored better in vacuum and polyethylene bag upto third day. Physiological weight loss, firmness, TSS, acidity and decay loss were respectively (4.41%, 7.76kg/cm2, 7.17ºBrix, 0.54%, 38.33%) upto second day of storage. Edible coating tested in the experiment enhanced browning of mushrooms during storage under ambient conditions.en_US
