[PERSON] et al. [69] found that gum concentration correlated with color parameters. Similarly, [PERSON] and [PERSON] [70] claimed that the yellowness-blueness index (b*) of the drink samples stabilized with Iranian native hydrocolloids (Persian gum and tragacanth gum) was significantly higher than that of the sample without hydrocolloids. This may be due to the color characteristics of hydrocolloids, their concentrations and possible interactions with salts and sugars [28].
