Abstract
The black tea from more types of hot drinks mission in Iraq in particular and beverage job in all parts of the world in general, because the tea because of the composition of chemicals have a close relationship to human health, and is the tea of hot drinks that contain antioxidants, dubbed (Flavoonoidz) which protect the arteries as these antibiotics inhibit cholesterol gathered on the inner walls of the arteries and thus maintain human health. For this reason, has been studied load microbial for tea and to make sure they are free of harmful bacteria and ensure the safety of the product depending on the specification of Iraq through microbial content knowledge and comparing them to standard microbial content and microbial tests included (The Total Count of Bacteria, Molds and Yeasts promised last resort counting total Coliform) and has also study the composition of chemical tea by estimating the metal elements trace like element(Lead, Copper, Iron, Cadmium, Zinc) for black tea available in the local Markets of the City of Baghdad and fourteen brand include (Prairies, Lions, Knock, Blable).for tea Black Phil and type (Jehan, Perfume, Apple, Mahmud, Mahboba) type of black tea filled and (Ahmed Hill, Lipton, Alkozy peach, AlkozyCurrant,Ahmed perfumed) for the type of tea bags is melting fast. Taking the test results showed the presence of Microbial numbers of bacteria, yeasts and molds in tea products, as well as showing that all these free samples of the total Coliform. The test results showed chemotherapy for a higher concentration of the Lead was (0.2263µg/g) for mark tea prairies, while appeared less concentration of the Lead was (0.0000µg/g) ofTea mark (knock, Apple, Mahmud, Mahboba).As for Cadmium element higher concentration was (0.0426μg / g) for tea sign prairies and appeared less concentration of Cadmium was (0.0009μg / g) for tea brand apple. As for the Iron element and higher concentration was (2.6117μg / g) for tea brand Lipton and less focus of iron elemental appeared (0.3868μg / g) for tea brand Mahboba. As for the element Copper higher concentration was(0.2798μg / g) for tea sign Alkozy peach and less concentration of the element Copper appeared (0.1490μg / g) for tea brand perfumed. As for Zinc the highestlevelofthe element concentration was(0.0196 µg/g)sign to Lipton tea and less focus of the element concentration was(0.0026 µg/g)sign to apple tea.
