Identification of Chemical Compounds and amount of CarbohydratesSsoluble in Trehala manna

One of the most challenging issues in food and pharmaceutical industries is finding effective and safe saccharides from natural sources instead of the synthetic counterparts which can have side effects. In this regard, Trehala manna is considered a promising natural source of sugar and produced by Echinopes in response to insect activity.

The highest percentage of protein (2.97%), fat (0.87%), moisture (5.83%), fibre (0.83%) and ash (3.51%) was related to samples in Jahrom, and followed by Sabzevar, Mehriz, Jahrom, and Banaroyeh, in order of magnitude. Benaroyeh sample had the highest proportion of trehalose (17.11). However, Shiraz sample had the highest total sugar content (115 mg/g) and water-soluble sugar (45 mg/g) among the samples.The values of sucrose, glucose, fructose were ranged 2.4-8.2 (mg/gr), 7.6-4.5 (mg/gr) and 4.4-1.2 (mg/gr), respectively. In all cases, there were significant differences (p<0.05).

The origin of Trehala manna in different regions of Iran significantly affect their chemical components, especially trehalose. In this regard, Trehala mana from Benaroyeh region can be used as a proper source of trehalose (17.11%) for industrial purposes and the production of functional food.
