Effects of li pid edible coating (glycerol monoesty arat) containing essentia l oil of th yme on the oyster mushroo m’s shelf ife

The aim of this study w s to eval ate the effect of glycerol Monoestyarat coating on the shelf life of oyster m shroom a nd thyme. So, thyme essentialoil w as extracted by Clevenger, w s analyzed using GC-MS with glycerolconcentrations Monoestyarat mus hrooms w ere used for coatin g. After packaging, the mushrooms for 15 days at 4 œ C refrigerate d samples and testsevery 3 days physicochemical, textural a d sensory properties wereeval uated. Most thyme essential oil comp unds of caroacrol (1/43%),Parasymyn (19%) and thymol (8/14 p ercent).
