In this study the rheological and textural properties of Iranian white cheese produced by ultrafiltration technique containing gum tragacanth and xanthan each in the range of 0-0.1%, and basil seed and linseed mucilage each in the range of 0-0.2% were evaluated. According to the results obtained, values of Elastic (G/) and viscous (G//) moduli increased with increasing frequency sweep in all the cheese samples. G/ was always greater than G//. The values of G/ and G// in the sample containing 0.05% of gum tragacanth, 0.05% of xanthan gum and 0.1% of basil seed mucilage and the sample containing 0.05% of xanthan gum, 0.1% basil seed and 0.1% linseed mucilage were maximum. Also, in samples containing 0.1% of xanthan gum and 0.2% of linseed mucilage and containing 0.1% of gum tragacanth were minimum. With increasing basil seeds mucilage in the samples, hardness, cohesiveness, gumminess and chewiness increased in comparison with the control sample (p < 0.01). According to the results obtained, for preparation of white cheese produced by ultrafiltration technique, application of 0.05% of gum tragacanth, 0.05 % of xanthan gum and 0.1 % of linseed mucilage, is recommended.
