Abstract
The 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.
