Study of the physicochemical, microbial and sensory properties of hamburgers enriched with turmeric and omega -3 loaded nanoliposomes. (English)

In this study, the effect of turmeric extract and omega -3 encapsulated with soy lecithin on the characteristics of hamburger during the 12 -day storage period was investigated. The results showed that during storage for 12 days, the highest pH and water holding capacity were related to the control sample. The initial moisture content of hamburgers was about 52%, which decreased significantly after the storage period (p<0.05). The lowest shrinkage was compared to the control sample, and the highest cooking loss was observed on the first day of storage. In all the investigated days, the highest volatile nitrogenous compounds was related to the control sample. Free fatty acids increased significantly during storage (P<0.05). The samples containing the extracts were not significantly different from the control samples in terms of texture characteristics. Encapsulated treatments had lower bacterial counts than free extracts. The control sample significantly received the lowest score in all sensory characteristics. In general, the quality of hamburgers containing fine -coated turmeric extract and omega -3 improved compared to the control sample . [ABSTRACT FROM AUTHOR]
