A novel method for predicting cadmium concentration in rice grain using genetic algorithm and back-propagation neural network based on soil properties.
Environmental science and pollution research international
Oct 24, 2018
Heavy metal pollution is a global ecological safety issue, especially in crops, where it directly threatens regional ecological security and human health. In this study, the back-propagation (BP) neural network optimized by the genetic algorithm (GA)...
The antibacterial activity of rhamnolipid biosurfactant is pH dependent.
Food research international (Ottawa, Ont.)
Sep 6, 2018
Rhamnolipid (RL) biosurfactants have been studied as agents to control the growth of food pathogens however, to be successful applied as antimicrobial agent in food, is important to determine the effect of environmental conditions on RL activity. Onc...
Antibacterial activity and its mechanisms of a recombinant Funme peptide against Cronobacter sakazakii in powdered infant formula.
Food research international (Ottawa, Ont.)
Aug 13, 2018
Cronobacter sakazakii (Cs) is a typical foodborne bacterium that infect powdered infant formula (PIF) worldwide. In this study, a recombinant antimicrobial peptide, branded as Funme peptide (FP)was applied to protect PIF from Cs contamination. The re...

rGO-NS SERS-based coupled chemometric prediction of acetamiprid residue in green tea.
Journal of food and drug analysis
Jul 4, 2018
Pesticide residue in food is of grave concern in recent years. In this paper, a rapid, sensitive, SERS (Surface-enhanced Raman scattering) active reduced-graphene-oxide-gold-nano-star (rGO-NS) nano-composite nanosensor was developed for the detection...
Rapid screening and multi-toxin profile confirmation of tetrodotoxins and analogues in human body fluids derived from a puffer fish poisoning incident in New Caledonia.
Food and chemical toxicology : an international journal published for the British Industrial Biological Research Association
Dec 30, 2017
In August 2014, a puffer fish poisoning incidence resulting in one fatality was reported in New Caledonia. Although tetrodotoxin (TTX) intoxication was established from the patients' signs and symptoms, the determination of TTX in the patient's urine...
Method for the determination of Pb, Cd, Zn, Mn and Fe in rice samples using carbon nanotubes and cationic complexes of batophenanthroline.
Food chemistry
Dec 27, 2017
Among cereals, rice is the second most cultivated staple crop in the world. It may be contaminated by toxic heavy metals present in water or soil. Therefore, monitoring the presence of heavy metals in rice and its products is a matter of a great impo...
A novel N,N'-bis(acetylacetone)ethylenediimine functionalized silica-core shell magnetic nanosorbent for manetic dispersive solid phase extraction of copper in cereal and water samples.
Food chemistry
Dec 27, 2017
Determination of heavy metals at trace levels has a great deal of importance due to their undesirable effects on human life. In this study, N,N'-bis (acetyl acetone) ethylenediimine (FeO@SiO-EDN) was synthesized and applied for dispersive solid phase...
Label-free screening of foodborne Salmonella using surface plasmon resonance imaging.
Analytical and bioanalytical chemistry
Dec 26, 2017
It is estimated that 95% of the foodborne infections are caused by 15 major pathogens. Therefore, rapid and effective multiplex screening techniques for these pathogens with improved efficiencies could benefit public health at lower costs. Surface pl...
High-sensitivity direct analysis of aflatoxins in peanuts and cereal matrices by ultra-performance liquid chromatography with fluorescence detection involving a large volume flow cell.
Journal of environmental science and health. Part. B, Pesticides, food contaminants, and agricultural wastes
Dec 26, 2017
This paper reports a sensitive and cost effective method of analysis for aflatoxins B1, B2, G1 and G2. The sample preparation method was primarily optimised in peanuts, followed by its validation in a range of peanut-processed products and cereal (ri...
Optimization of Solvent Terminated Dispersive Liquid-Liquid Microextraction of Copper Ions in Water and Food Samples Using Artificial Neural Networks Coupled Bees Algorithm.
Bulletin of environmental contamination and toxicology
Dec 26, 2017
A multivariate method based on solvent terminated dispersive liquid-liquid microextraction was developed for the determination of Cu ions in aqueous samples. In the proposed approach, di-2-ethylhexylphosphoric acid, xylene and acetone were used as ch...
