Background and Objectives:
Due to the bioactive components, the use of bioactive compound improves the qualitative properties of foods. The aim of this study was to evaluate the effect of Ocimum basilicum and Urtica dioica extract on the physico-chemical and sensory properties of sausage.
Materials and Methods:
U. dioica extract at 0, 0/1, 0/2 and 0/3 % and O. basilicum extract at 0, 0.3, 0.4 and 0.5% individually and in the ratios of 0.15-0.20 and 0.25 - 0.35 % of U. dioica – O. basilicum extract added to sausage formulation and the experiments were carried out on treatments.
Results:
control sample (whithout any extract) had the highest pH value, fat, and moisture content and had the significant difference (p<0.05) in comparsion with other treatments. The treatments containing 0.1 % U. dioica extract, had the lowest pH value and moisture and highest protein content. The lowest fat and the highest ash content related to 0.3 % U. dioica extract. Regarding free radical scavenging activity, the U. dioica extract had more antioxidant activity individually and in comparison to O. basilicum extract and the compound extracts. Among the treatments, the treatment containing 0.1 % U. dioica extract showed the highest scores of taste and color.Treatments containing 0.3% U.dioica extract and the mixture of U.dioica - to O. basilicum extract (0/25-0/35%) represented the highest score of appearance and texture respectively. In terms of overall acceptance, after the control sample, the treatment containing 0.2 % U.dioica extract had the highest score.
Conclusion:
The Urtica dioica extract showed the better results compared to Ocimum basilicum extract separately or combination of two extracts.
