Abstract

The most of medicinal plant seeds contain of polysaccharides with specific functional properties and used as a hydrocolloids source. Mucilages are polysaccharides with long chain molecules. In order to study the effect of different temperatures on the amount of mucilage and dry matter extraction (DME) in two medicinal plants of Plantago psyllium L. and Plantag omajor L. an experiment was carried out in a randomized complete block design with three replications at five temperature levels: 30, 40, 50, 60 and 70 °C. The results showed that in P. psyllium, the highest amount of mucilage (24.55 ml) and DME were obtained from 40 °C treatments and the lowest amounts of mucilage and DME were recorded at 70 °C. It found that when the temperature reached from 60 to 70 °C, the amount of DME in P. psyllium was decreased significantly, so that at 70 °C the amount of DME decreased was 56% in compared of 60 °C. In P. major: The highest amount of mucilage (28.6 ml) was obtained at 40°C and the lowest of it was observed at 70 °C. The highest (0.897 gram) and the lowest (0.523 gram) amount of DME was obtained at 30 °C and 70 °C in P. major, respectively. In general, the amount of extracted mucilage seems to depend on the water-to-grain ratio, and as the ratio decreases, the amount of mucilage decreases at high temperatures.
