Single-factor and response surface methodologies (RSM) were used to systematically optimize the hydrolysis conditions of the food samples to extract the maximum amount of sialic acid. Chromatographic conditions were also adjusted. In foods containing sialic acid, we observed a strong linear relationship between s...

Update of the Moroccan Food Composition Tables: Towards a more reliable tool for nutrition research
Publication date: Available online 26 December 2019Source: Journal of Food Composition and AnalysisAuthor(s): Mohamed Khalis, Vanessa Garcia-Larsen, Hafida Charaka, Meimouna Mint Sidi Deoula, Khaoula El Kinany, Abdelilah Benslimane, Barbara Charbotel, Amr S. Soliman, Inge Huybrechts, Ghada A. Soliman, Nadia Slimani, Karima El RhaziAbstractThe last food composition table (FCT) for Morocco was published in 1984 and has not been updated since. Our study aimed at bringing this FCT up to date, taking into account the current Moroccan population’s diet. To collate nutrient information, we used the indirect method based on ...

Impact of Holder pasteurization on essential elements from human donor milk: total contents and protein-binding profiles
Publication date: Available online 23 December 2019Source: Journal of Food Composition and AnalysisAuthor(s): Rafaella R.A. Peixoto, Sonia Fernández-Menéndez, Belén Fernández-Colomer, Ana I. Pérez Vaquero, Solange Cadore, Alfredo Sanz-Medel, María L. Fernández-SánchezAbstractHolder pasteurization is a thermal treatment commonly applied to milk in human milk banks. However, the application of heating processes can affect the actual composition of milk. In this work, the effect of Holder pasteurization on essential elements in donor human breast milk was studied, includ...

Sinapic acid derivatives in microwave-pretreated rapeseeds and minor components in oils
Publication date: Available online 20 December 2019Source: Journal of Food Composition and AnalysisAuthor(s): Yanxia Cong, Mingming Zheng, Fenghong Huang, Changsheng Liu, Chang ZhengAbstractMicrowave pretreatment has been considered to improve the quality of rapeseed oil for canolol generation. Canolol is assumed to be formed by the decarboxylation of sinapic acid (SA). In this work, sinapic acid derivatives in 39 microwave-pretreated rapeseeds and their roles in the enhanced oxidative stability of rapeseed oils were investigated. The average contents of sinapic acid derivatives in rapeseeds, including (from high to low) s...

Variations in total As and As species in rice indicate the need for crop-tracking
Publication date: Available online 16 December 2019Source: Journal of Food Composition and AnalysisAuthor(s): Fabiana Roberta Segura, Daniel Fernandez Franco, Júlio José Centeno da Silva, Bruno Lemos BatistaAbstractRice is a significant source of arsenic (As) and high consumption is noted for the Brazilian population. Inorganic-As (i-As) accumulation in rice strongly depends on geochemical soil characteristics. These characteristics may be completely different from site to site and it is expected that rice grains grown in different cities would present significant differences concerning total As (t-As) and i-...
