1 - Evaluation of <i>Zataria multiflora </i> and <i>Salvia leriifolia</i> extract on the physicochemical and organoleptic characteristics in sausage formulation during refrigerated storageFood and Health , شماره 5 , سال 2 , تابستان 2019In the present study, hydroalcoholic extract of dried and powdered plants was prepared. After producing the treatments, moisture, pH, ash, protein, and fat content, DPPH radical scavenging activity, and color parameters, and sensory evaluation in sausage samples during چکیده کاملIn the present study, hydroalcoholic extract of dried and powdered plants was prepared. After producing the treatments, moisture, pH, ash, protein, and fat content, DPPH radical scavenging activity, and color parameters, and sensory evaluation in sausage samples during 45 days of cold storage were studied. The lowest and highest of pH value was related to treatment with the mixture extracts (0.25%) and Z. multiflora extract (1.5%) respectively. The lowest and highest protein content was related to 1% S. leriifolia and 2% Z. multiflora extract, respectively. Over time, the fat content in the control sample and all treatments has declined, also, the protein and ash content in treatments has decreased and increased respectively. Over time and with increasing the extracts concentration, L*, a* and b* values in all treatments decreased, increased, and decreased respectively. S. leriifolia extract has a more significant effect on the DPPH test in comparison with Z. multiflora extract. Two herbal extracts had a significant effect on the sensorial characteristics of all treatments. It can be said that, in terms of color parameters and free radical scavenging activity, the treatments with S. leriifolia extracts were better than control and treatments containing Z. multiflora extracts, while, the physicochemical and sensorial properties of recent treatments were better than S. leriifolia extracts and control. پرونده مقاله -

2 - Quality assessment of unfermented sausage by partial replacement of sodium nitrite with ethanolic extracts of <i>Rosmarinus officinalis</i> and <i>Berberis vulgaris</i>Food and Health , شماره 2 , سال 4 , بهار 2021In this research, nitrite was partially replaced with different concentrations of Berberis vulgaris and Rosmarinus officinalis (0, 30, 60, 90 mg/kg) extracts in the unfermented sausage. Samples were kept at refrigerator temperature and physicochemical and organoleptic e چکیده کاملIn this research, nitrite was partially replaced with different concentrations of Berberis vulgaris and Rosmarinus officinalis (0, 30, 60, 90 mg/kg) extracts in the unfermented sausage. Samples were kept at refrigerator temperature and physicochemical and organoleptic evaluations of treatments were performed. The findings showed an increase in moisture and ash content and a decrease in fat and protein content, and IC50 by increasing the storage time. The highest level of antioxidant activity was reported for treatment with 90 mg/kg R. officinalis extract. As for sensory properties, 60 mg/kg treatment showed the highest sensory score after the control sample; however, 30 mg/kg treatment had the highest score in terms of consistency after the control sample. It can be concluded that 60 mg/kg R. officinalis extract has a better potential to improve the qualitative characteristics of unfermented sausage and it can be a proper substitute for decreasing the nitrite in sausage formulations. پرونده مقاله -
