| Frequent nut intake is associated with protective effects against cardiovascular diseases. In addition to the generally high contents of unsaturated fatty acids, polyphenol compounds seem to be also implicated in health promoting effects of nuts due to their antioxidant properties. In this way, eleven different kinds of nuts, including pinhao seeds (Araucaria angustifolia) and Brazil nuts (Bertholletia excelsa), typical of Brazil, were analyzed for the content of phenol compounds, including the potent anti-mutagenic and anti-cancer ellagic acid, and antioxidant capacity of methanolic extracts. The antioxidant capacity varied a hundred times among the different nuts, from 1.2 to 120 mg of Trolox equivalents.100 g-1 (FW). Total ellagic acid was determined... |

| Abstract This work presents an investigation of the activity concentration (AC) of naturally occurring radionuclides in 26 samples of seasoning and nuts utilized for Brazilian population. The samples were measured using gamma spectroscopy technique with a high-purity germanium detector. The analysis shows that K-40 AC was measured in all samples, and its AC ranges from 21.0 Bq/kg to 1288 Bq/kg. The highest K-40 AC was measured for cheiro verde, a Brazilian seasoning made of chives (Allium schoenoprasum) and parsley ( Petroselinum crispum), while annatto, made with the fruit of Bixa orelhana , presented the lowest AC. Brazil nut (Bertholletia excelsa ) presented the highest AC for Ra-226 and Ra-228 with 24 Bq/kg and 25.7 Bq/kg, respectively, and black... |
