The importance of food as food additives for this plant syphilis because of the characteristics of life and chemical, which can be positively reflected on the health status of the consumer after adding it as extracts or as drying flowers to yoghurt, which is one of the dairy products as an important food consumed from all human age groups. In this study, a number of cold water extracts were prepared (R1), yoghurt with 2% cold water extract, R2 yoghurt with 4% cold water extract (R3) yoghurt with 6% cold water extract. The oil extracts consisted of (R4) yoghurt with the addition of oil extract 2%, R5 yoghurt with the addition of oil extract by 4%, R6 yoghurt enriched with the addition of oil extract 6%. Important active compounds that are conservation the studied samples were detected. such as tannins, soap, flavonoids, alkaloids, turbines and steroids, as well as the presence of volatile oil and used the infrared spectroscopy technique FTIR-8300 Fourier Transform Infra-Red Spectrophotometer. Sensory tests were conducted for the yogurt samples added to the Rosa sp. extract. It can be concluded that the addition of a specific percentage of the Rosa sp. extract to the sample of the study, the yoghurt and for different periods of time, led to stopping and sometimes curbing the biological effectiveness of bacterial growth which is under study. As well as the addition of both water extracts and oil extract has a positive effect in maintaining the qualitative and sensory characteristics and increase the time period of prolongation of the preservation of yogurt during cold storage.
