Abstract :

Introduction: Hydrocolloids (gums) are components of food ingredients that are affected bythermal treatments during transportation, processing, storage and distribution of food. In thisstudy, the effect of heat treatment on the color changes, rheological and textural (firmness,adhesiveness and consistency) properties of Basil seed gum are investigated.Materials and Methods: Basil seed gum is extracted in order to evaluate the rheological,textural properties and color. Solutions with different concentrations were prepared and weresubjected to different thermal treatments (25, 50, 75, 100, 121°C, for 20 min).Results: Applied thermal treatments increased the viscosity of Basil seed gum. Texture of theprepared gels had a good resistence against heat treatments and hardness, adhesiveness andconsistency values of Basil seed gum gel (3%) at 121°C were 51.3gr, 23.75 gr/s, 211.99 gr/s.By increasing the temperature of the treatment, the color of the samples became brighter(increase in L).Conclusion: The results indicated that Basil seed gum has pseudoplastic behavior and Powerlaw model is suitable to evaluate it.
