چکیده مقاله:
Persian gum (PG) is a type of exudate gum which naturally secretes from the barks of mountain almond trees (Amygdalus scoparia Spach).The gums are collected from two provinces (Fars and Eastern Azerbaijan) and after that they are categorized at 4 levels based on color, then pulverized and some of their properties investigated. Our findings show that PG is an acidic gum (pH=4.4±0.02), with moderate moisture (8.8±0.30% w/w), low protein (0.20±0.006% w/w) and fat (0.35±0.18% w/w) contents. Its specific rotation is levorotatory and the water absorption capacity and cold water insoluble gel are 12.65±0.38 g/g and 71.28±0.26 % w/w, respectively.
