Capillary Electrophoresis in Wine Science
2016
International audience; Capillary electrophoresis appeared to be a powerful and reliable technique to analyze the diversity of wine compounds. Wine presents a great variety of natural chemicals coming from the grape berry extraction and the fermentation processes. The first and more abundant after water, ethanol has been quantified in wines via capillary electrophoresis. Other families like organic acids, neutral and acid sugars, polyphenols, amines, thiols, vitamins, and soluble proteins are electrophoretically separated from the complex matrix.Here, we will focus on the different methodologies that have been employed to conduct properly capillary electrophoresis in wine analysis.Two examp…
Bread aroma
2020
: This chapter will review the different synthetic pathways of bread volatiles in conventional white bread. The influence of traditional and innovative raw materials and breadmaking processes on the formation of volatiles will then be discussed. Next, extraction and analytical methods used to identify volatiles that participate in bread aroma will be presented. Volatiles that have been identified in freshly baked white bread will be listed and the ones that are potent odorants highlighted. Finally, the techniques employed by the baking industry to enhance bread aroma will be described.
Does toddlers' food intake differ according to variations in fat, salt or sugar in foods?
2009
National audience; In many developed countries, governmental policies encourage reduction of fat, salt and sugar consumption. However, such reductions are likely to impact the palatability of foods, in particular in children, whose food intake is largely influenced by food's sensory features. The extent to which young children's food intake varies according to fat, salt and sugar content is imperfectly known. This study aimed to evaluate whether toddler's food intake varied from one meal to the other (1) during lunches where salt or fat contents were modified in some foods and (2) during snacks where sugar or fat contents were modified. Sixty-four children (24–36 months old) participated in…
Effect of growing area on tocopherols, carotenoids and fatty acid composition of Pistacia lentiscus edible oil
2014
In this investigation, we aim to study, for the first time, the effect of the growing area on tocopherols, carotenoids and fatty acid content of Pistacia lentiscus fixed oil. Fruits were harvested from eight different sites located in the north and the centre of Tunisia. Tocopherols, carotenoids and fatty acid content of the fixed oils were determined. The highest carotenoid content was exhibited by Feija oil (10.57 mg/kg of oil). Oueslatia and Tabarka oils displayed the highest α-tocopherol content (96.79 and 92.79 mg/kg of oil, respectively). Three major fatty acids were determined: oleic, palmitic and linoleic acids. Oleic acid was the main fatty acid presenting more than 50% of the tota…

COVID-19 and molecular mimicry: The Columbus’ egg?
2020
Highlights • Recently, this Journal published a report about Guillain-Barré syndrome associated with COVID-19 infection. • Guillain-Barré syndrome can be due to molecular mimicry phenomena. • Molecular mimicry had already been described in another SARS. • It could explain the autoimmune signs and symptoms that some patients affected by SARS-CoV-2 can experience.
