Background and Objectives: Clove essential oil is used due to its biological activity related to human health (antimicrobial and antioxidant) and flavoring application to enrich traditional aroushe cheese embedded in nanoencapsulation.
Materials and Methods: Average particles size, polydispersity index and dynamic light scattering assessments were determined on nanoencapsulated clove essential oil (NCEO). Afterwards, the samples were fortified using Aroushe as a local cheese from Sangsar tribe in Semnan province, Iran, walnut powder (0, 1.9 and 3 % w/w) and NCEO (0, 0.3 and 0.6 % w/w), which physicochemical, rheology, microbial, sensory evaluation and microstructural characteristics were investigated during 40 days of shelf life in cold storage. Variance analysis was conducted for evaluation and the tests were performed in three repetitions.
Results: NCEO caused a decline trend in pH feature due to phenolic acids and antioxidant components as well as the highest and lowest moisture levels were reported for control and Aroushe cheese with 3 % walnut and 0.6 % NCEO (AWC4) over 40 days. The most contents of fat and ash were obtained for AWC4 and Aroushe cheese with 3 % walnut and 0.3 % NCEO (AWC3) had the maximum protein. The microbial population was not distinguished in all treated samples on the 20th days of shelf life and AWC3 indicated the highest hardness, cohesiveness and springiness; nevertheless, AWC4 had the greatest adhesiveness. The maximum score was attained for AWC3 in overall acceptance of sensory evaluation and microstructure images prepared using a scanning electron microscopy exhibited that texture was uniform.
Conclusions: As a result, AWC3 was an optimal selection for treated cheese sample and had the ability to apply as biofunctional natural products.

Highlights
- In Sangsar region, Aroushe is prepared by roasting fresh sheep cheese with addition of turmeric and flour.
- Walnut powder and nanoencapsulated clove essential oil (NCEO) had improved some texture factors for cheese samples on account of protein and fat.
- NCEO caused a decline trend in pH feature due to phenolic acids and antioxidant components
- Cheese with 3 % walnut and 0.3 % NCEO was the most interesting and had necessary potential for industrial production and available to public.
