The aim of this study was to evaluate a Guar/Tragacanth gum-based edible coating used on Cheddar cheese during ripening for 90 days. Five samples of Cheddar cheese blocks were coated by different coating materials in triplicate as following: C, coated with polyvinyl acetate as control, GC, coated with 1% Guar gum and TG1, TG2, and TG3, coated with 0.75, 1, and 1.25% Tragacanth gum, respectively. All samples were kept at 8 2 C for 90 days. The results showed that total mesophilic aerobic bacteria counts were altered under the effect of edible coating materials (p < .01). The moisture and protein contents of the samples decreased and increased during ripening, respectively (p < .01). pH, acidity, fat in dry matter, tyrosine, and tryptophan contents of samples also significantly affected with edible coatings (p < .01). The free fatty acid composition of samples affected by all edible coatings. Trichloroacetic acid soluble nitrogen as a percent of total nitrogen, lipolysis, and sensory evaluation of samples were not significantly different (p > .01).
