Assessment of Cellular Mutagenicity of Americano Coffees from Popular Coffee Chains

摘要: Coffee is a popular beverage worldwide, but coffee beans can be contaminated with carcinogens. The Ames Salmonella mutagenicity test often used for analysis of carcinogens mutagenicity. However, previous studies have provided controversial data about the direct based on results. This study was conducted to determine Americano results from test. samples without additives that were served by five international chain restaurants subjected using Typhimurium tester strains TA98, TA100, and TA1535. levels bacterial revertants in chains lower than twofold criterion control sets, no significant dose-response effect observed or rat liver enzyme activation. These indicate coffees selected possessed mutagenic activity findings suggest low risk support use other methods confirm nonmutagenicity products. are consistent most recent epidemiological reports.
