| Abstract This study evaluated the action at the cellular level of long life whole milk, full type of six renowned companies operating in the Brazilian market, as well as in other South American countries. The evaluation was performed using root meristem cells of Allium cepa L., at exposure times 24 and 48 hours, directly in milk products marketed. The results indicated that all the milk samples reduced root meristem cell proliferation, proving, in this study, a significant cytotoxic effect. Still, exposure to milk resulted in a significant frequency of mitotic spindle changes in meristem cells, characterizing these foods as genotoxic and mutagenic under the study conditions. It can be concluded that the long life milk samples caused significant genetic... |

| Abstract Powdered juices are widely consumed by the population especially because of their convenient preparation, availability in various fruit flavors and low cost when compared to other industrialized beverages. They have complex formulation, consisting of several classes of food additives. However, there are no scientific studies on the toxicity of these foods. Thus, this study evaluated the toxicity at the cellular level of industrialized powdered juices of orange and guava flavors of three different food companies. This analysis was made using root meristem cells of Allium cepa L., at the exposure times of 24 and 48 hours, and two concentrations, 30 g/1000 mL, considered ideal for consumption according to the label of the products, and 30 g/500 mL.... |
