Phenolic contents, antioxidant properties, and sensory profiles of wheat round rolls supplemented with whole grain cereals

Whole cereal flours (buckwheat, barley, and oat) and wheat bran were used to substitute 20% of white bakery wheat flour to prepare round rolls. Round roll quality was evaluated by determining total phenolic and total flavonoid contents, antioxidative capacity, the content of lipid hydroperoxides (primary oxidation products), and sensory profiling. Moreover, the stability of the phenolic compounds and antioxidant behaviour throughout processing was studied. Technological processing does not cause any significant loss of phenolics (less than 5%). A significant increase in antioxidants and phenolics of the flour mixtures and final products were observed compared to those of white wheat round rolls (as control). Buckwheat and barley round roll crumbs contained the highest total phenolic and total flavonoid contents, and were the most effective in enhancing antioxidant activity, which increased 15-fold and 8-fold, respectively, when compared to the control roll. The tested cereals effectively retarded formation of lipid hydroperoxides (from over 50% to control), which are undesirable from both a nutrition and storage/shelf life perspective. The results of sensory analyses showed that such bakery products are accepted by consumers with the exception of the product made with oat flour, where a reduction in the oat content would be preferable

Genotypic variation in nutritive and bioactive composition of foxtail millet

Foxtail millet (Setaria italica) genotypes with red and yellow colour of grain bran were examined and compared for their content of nutritive components, fatty acids and phenolic compounds profile. Moreover, the antioxidant properties were investigated using three different methods. Foxtail millet genotypes contained 14.2% of protein, 5.0% of fat and 4.3% of soluble sugars, on average. Linoleic acid was the most abundant unsaturated fatty acid and palmitic acid was the most abundant saturated fatty acid. Four hydroxybenzoic acids (gallic, protocatechuic, vanillic and syringic acid) and two hydroxycinnamic acids (ferulic and p-coumaric acid) were identified and quantified. All genotypes exhibited effective inhibition of free radicals. Nevertheless, ferrous ion chelating activity was weak. Antioxidant properties of foxtail millet genotypes were closely associated with the presence of phenolics. A relationship between intensity of grain colour and antioxidant properties as well as phenolic compounds content, was observed. We can conclude that the content of evaluated parameters varied among foxtail millet genotypes, therefore their assessment and selection is desirable in order to cultivate crops and produce foods with advanced nutritional and antioxidant properties

Teaching and learning in a multilingual Europe: findings from a cross-European study

School classrooms within the EU are multilingual learning environments. The diversity of pupils in classrooms raises significant challenges for teachers, but to date, there are no data from large-scale surveys that compare views within and across European countries. A bespoke questionnaire was designed to examine views of current classroom learning environments with respect to the multilingualism. The questionnaire was piloted and subsequently completed by 2792 teachers across different European countries. Eleven countries provided sufficient data for analyses. Results from structural equation modelling showed that teachers’ attitudes could be reliably measured across Europe with the use of carefully devised questionnaire, whose loading and factor structure remained invariant across countries. Teachers’ views about multilingualism were most challenged by the numbers of children in their classes, not the percentage of multilingual pupils in the class. Countries differed in how they perceived multilingualism, with their differences leading to distinctive country clusters. Gender and education level (elementary vs. secondary) differences were also observed irrespective of country. These findings enhance our understanding of the role that the characteristics of teachers and their classrooms play in a multilingual setting across diverse European settings. The practical relevance of the results and new opportunities for teacher training are discussed

The original version of the article unfortunately contained errors. The following author e-mails were omitted, A Ralli, [email protected], I Dimakos [email protected]. There remained highlighted in yellow XXX (blinded for review) in the questionnaire section. This should be replaced with: Work Group 1 of COST IS 1401 (European Literacy Network). The footnotes and endnotes had been merged with footnotes. Footnote 1 should be Endnote 1, Footnote 2 should be Endnote 2, Endnote 3 should appear in the last sentence of DATA CLEANING AND MANAGEMENT section, next to the word "imputation" with a superscript. Endnote 3, top p. 10, should be Endnote 4, Endnote 4 should be Endnote 5, Endnote 5 should be Endnote 6, Endnote 6 should be Endnote 7. (F3), top, p. 9 should be F3 in plain font. On p. 12, the word ‘factors’ in the parenthesis should be capitalized (in Factors 1, 3 and 4). Finally Table 4 p should be * p <.05. The author name H.
