Journal ArticleDOI
Extraction procedures for the liquid chromatographic determination of thiamin, riboflavin and vitamin B6 in foodstuffs.
TL;DR: In this paper, a mixture of enzymes (α-amylase, papain and acid phosphatase) was used to extract vitamins B1, B2 and B6.
Journal ArticleDOI
Determination of folates in foods by high-performance liquid chromatography with fluorescence detection after precolumn conversion to 5-methyltetrahydrofolates.
TL;DR: It has been possible to show that the deconjugation of the folates by rat plasma conjugase was incomplete in foodstuffs whereas chicken pancreas conjugases effectively converted the different folate polyglutamates into folate diglutamate.
Journal ArticleDOI
Effects of processing steps on the phenolic content and antioxidant activity of beer
Céline Leitao,Eric Marchioni,Martine Bergaentzlé,Minjie Zhao,Luc Didierjean,Behnam Taidi,Saïd Ennahar +6 more
TL;DR: This study showed that the total antioxidant activity remained unchanged throughout beer processing, as opposed to the polyphenolic content, which showed a 3-fold increase.
Journal ArticleDOI
Fate of polyphenols and antioxidant activity of barley throughout malting and brewing
Céline Leitao,Eric Marchioni,Martine Bergaentzlé,Minjie Zhao,Luc Didierjean,Laurence Miesch,Emilie Holder,Michel Miesch,Saïd Ennahar +8 more
TL;DR: In this paper, a chromatographic online antioxidant detection system was used to investigate the phenolic contents of barley and malt extracts and their corresponding antioxidant activities using a reverse phase HPLC and compounds eluting from the column were submitted to two UV-visible detections.
Journal ArticleDOI
Fluorimetric determination of niacin in foods by high-performance liquid chromatography with post-column derivatization
TL;DR: In this article, a method to determine the content of niacin in various foods by liquid chromatography is proposed and includes hydrochloric acid hydrolysis of the sample, pre-column conversion of the different vitamers (NAD, NADP, nicotinamide and nicotinic acid) into nadiic acid by alkaline acid, separation on a C18 stationary phase, post-column derivatization by UV irradiation in the presence of copper (II) ions and hydrogen peroxide, and fluorimetric detection.
