Knowing the quality of mill streams is very important for getting flours with improved quality. In the present work, 49 mill streams, obtained by milling common wheat with an industrial roller mill, were characterized in terms of phenolic content, antioxidant activity and iron content. The antioxidant activity was estimated using different methods: DPPH-radical scavenging, Trolox equivalent antioxidant capacity, and iron reducing antioxidant power.

The aim of this study was to investigate the fermentation behaviour, antioxidant activity and rheological behaviour of the sourdoughs prepared with Lactobacillus helveticus and Kluyveromyces marxianus. The final acidity of the sourdough after 18 h of fermentation was higher at higher temperatures (40C) and for the formulations with whole rye flour. The highest lactic/acetic acid ratios were obtained in case of more fluid sourdoughs fermented at

Knowing the quality of mill streams is very important for obtaining standardized flours with intended qualities for specific applications. The physicochemical and rheological quality of wheat flour mill streams obtained through industrial milling were analyzed. Rheological behavior was tested using alveograph, rheofermentograph, and mixolab equipment. The results obtained indicate that the starch damage, protein quality, and rheological properties
