Abstract
Three types of date crops were used for the 2016 season: Al-Zehadi, Al-Khestawi and Al-Khedrawi. The most common varieties in Iraq are Al-Zehidi, which is estimated to be 615.2 thousand tons, according to the statistics of the Directorate of Agricultural Statistics/ Ministry of Planning. Al-Khestawi, elongated and oval-shaped fruit, whose thin crust usually separates from the meat at maturity and is eaten at all stages of maturity. Al-Khedrawi, is one of the finest soft varieties. The total production of dates for each of Al-Zehadi, Al-Khestawi and Al-Khedrawi varieties was (333.2, 64.5, 30.8) thousand tons respectively, and their estimated at (54.2, 10.5, 5)% respectively of the total production of dates. Dates have known economic and nutritional benefits and it is an old heritage tradition adopted with milk. The current study was concerned with the use of the water extract of the dates and their role as vital promoters (Prebiotics) for manufacture of fermented and therapeutic products by using biocompatible bacteria such as Lb. acidophilus and Lb. plantarum and mixed plant by 5% (size/ size) separately using skim milk 12% which supported by different concentrations of date extracts (5, 10, 15 and 20)% and qualitative, The logarithm of bacteria significantly increased and their intestines was increased in the therapeutic with the increase of the added date extract, The results of the study showed that the concentration of 15% of the date extracts (Al-Zehadi, Al-khestawi and Al-Khedrawi) was the best, which reduced the time of the generation significantly for the used ones. the generation time for Al-Khedrawi extract of Lb. acidophilus and Lb. Plantarum were 59 and 57 respectively. The results showed an increase in the percentage of phenolic compounds in therapeutic milk ferments when supplemented with date extracts (Al-Zehadi, Al-kestawi and Al-Khedrawi) for the bio protective bacteria Lb. acidophilus and Lb. Plantarum and T1, T2, T3 and T4 were mixed in T3. The number of phenolic compounds (Apigenin, Gallic acid, and Qurcetine) in the T3 sample, supported by the Lb. acidophilus (2.33, 4.16 and 0.70), respectively, and to the Lb. Plantarum (2.81, 2.45 and 6.86), respectively. And mixed farm initiators (1.52, 1.83 and 1.88), respectively
