Fresh tofu samples were prepared and immersed in different solutions containing gelatin (1 and 2%) and Melissa officinalis L. oil (0.1, 0.3 and 0.5%) as antimicrobial activity. The samples stored up to 14 days under cooling conditions (4˚C). Melissa officinalis L. oil was chemically and microbiologically analyzed. Rheological properties and thixotropic effect were determined. The results indicated that blends of gelatin and Melssa officinalis L. oil exhibited dilatant flow behavior and all samples showed thixotropic effect. The effect of edible coating on weight loss, moisture content, texture properties, microbiological tests, and sensory evaluation of tofu samples were determined during storage period as an indication for shelf life and quality of tofu samples.
