Investigation of the distribution of deoxynivalenol and ochratoxin A contamination within a 26 t truckload of wheat kernels.

A study was conducted to determine the distribution of deoxynivalenol (DON) and ochratoxin A (OTA) in a lot of 261 of wheat kernels. Within this study, two different sampling and sample preparation strategies were carried out. On the one hand, following the official commission regulation 401/2006/EC, an aggregate sample out of 100 incremental samples was build, homogenized and prepared for laboratory analysis.

Bread enriched with green coffee extract has chemoprotective and antigenotoxic activities in human cells.

Recent studies have shown that bread supplemented with functional ingredients was more chemoprotective than nonsupplemented bread. Here we investigated components of a German wheat bread supplemented with green coffee antioxidants (GC) to assess basic biological activities in human cells in culture. We analyzed chlorogenic acid (ChA) in the bread and determined antioxidative activities.

Influence of prebiotics and antioxidants in bread on the immune system, antioxidative status and antioxidative capacity in male smokers and non-smokers.

Interest in functional foods is increasing. The aim of the present study was to investigate breads supplemented with functional components. One was bread supplemented with inulin, linseed and soya fibre (prebiotic bread).

Assessment of DNA damage and its modulation by dietary and genetic factors in smokers using the Comet assay: a biomarker model.

Methods are needed to assess exposure to genotoxins in humans and to improve understanding of dietary cancer prevention. The Comet assay was used to detect smoking-related exposures and dietary modulations in target tissues. Buccal scrapings, blood and faeces were collected from 38 healthy male volunteers (smokers and non-smokers) during a dietary intervention study with bread supplemented with prebiotics+/-antioxidants.
