A liquid chromatography-high-resolution mass spectrometry (LC-HRMS) method for the simultaneous determination of aflatoxins (B(1), B(2), G(1), G(2)), ochratoxin A, deoxynivalenol, zearalenone, T-2 and HT-2 toxins in wheat flour, barley flour and crisp bread was developed. Mycotoxin fragmentation patterns obtained by high-energy collision dissociation (HCD) were investigated to obtain quantitati...

Article history: Received on: 07/04/2015 Revised on: 22/04/2015 Accepted on: 11/05/2015 Available online: 20/06/2015 Genetically modified organisms (GMOs) and their raw materials used in processed foods should be analyzed and labeled. The aim of our study was to evaluate the present situation of the food products and to determine appropriate DNA isolation method in processed food products. Keep...

Abstract The simple extraction of flours samples followed by free amino acids determination procedures was studied and optimised. conditions derivatisation reaction with ninhydrin for chromatographic sum discussed. developed method processed in terms linearity, precision, accuracy, limits detection quantification. Moreover, capillary isotachophoresis HPLC methods were applied individual determi...

While developing radio frequency heat treatments for dried fruits and nuts, we used a heating block system developed by Washington State University to identify the most heat-tolerant life stage of red flour beetle, Tribolium castaneum (Herbst), and to determine its thermal death kinetics. Using a heating rate of 15 degrees C/min to approximate the rapid heating of radio frequency treatments, th...

Soy peroxidase enzyme obtained from isoelectic precipitation procedures was added to all-purpose flour (APF) to assess its effects on the rheological properties and consumer acceptability of yeast bread. A pH 4.8 isoelectrically precipitated fraction from soybeans was used because it produced the most precipitate and had about the same peroxidase activity as the other fractions. Gluten strength...

This paper aims to establish a detection method for simultaneous determining four additives in flour products: one simultaneously determines the acesulfame, sodium cyclamate, bromate, and calcium propionate through selection of ion chromatography pump flow rate, injection volume, eluent concentration, optimization sample pretreatment influence interfering ions. When using rate 0.8 ml/min, 200 µ...

CONFERENCE PROCEEDINGS '950 calories in any of the groups surveyed. The very satisfactory figures for iron, vitamin B,, and nicotinic acid are to be attributed to the use of high-extraction (8j-90 yo) flour. The consumption of vitamin C was also satisfactory in all groups except the poorer families in the Dublin slums. The principal source in Irish diets is the potato and it is likely that the ...
