In the present study, the effect of various natural food condiments (garlic, ginger,
pepper, tomato and onion) on the formation of heterocyclic amines (HAs) in
cooked camel meat was studied. In control sample, the amount of HAs MeIQx,
4,8-DiMeIQx...
In this study, starch based nanocomposite (starch/SnO2) was synthesized and used as an effective adsorbent
for the removal of Hg2+ from aqueous medium. The as-prepared starch/SnO2 nanocomposite was
characterized by means of the XPS, XRD, BET, FTIR,...
The zeta or electrokinetic potential describes the nanomaterials potential distribution and it is often a useful parameter to evaluate the adsorption of ionic pollutants on the nanomaterials surfaces, since it reflects the electrostatic interactions...
The aim of the present study was to determine the content of capsaicin and dihydrocapsaicin in Capsicum samples collected from city markets in Riyadh (Saudi Arabia), calculate their pungency in Scoville heat units (SHU) and evaluate the average...
High performance liquid chromatography–photodiode array (HPLC–PDA) method has been employed for the simultaneous determination of vitamin C (ascorbic acid) and aspirin (acetylsalicylic acid) in aspirin C effervescent tablets. Chromatographic...
In the present work, a rapid and sensitive ultra performance liquid chromatography-mass spectrometry method has been proposed for the analysis of capsaicinoids (nordihydrocapsaicin, capsaicin, dihydrocapsaicin, homocapsaicin, and...
Aflatoxins AFB1, AFB2, AFG1, and AFG2 are toxic secondary metabolites produced by
Aspergillus flavus and Aspergillus parasiticus and posses a potential threat to food safety. In
the present work, liquid–liquid extraction and...
In this study the determination of pesticide residues namely, malathion in cucumber collected from local markets in Riyadh city has been carried out. Samples of treated cucumbers were collected and analyzed during a 14 days period for
obtaining the...
A broad range of detection techniques used for practical analysis and detection of aflatoxins are available. This chapter highlighted some recent developments and new techniques about aflatoxins analysis in food via UPLC/MS. As shown, though there...
This chapter emphasized number of recent techniques for the analysis of acrylamide in food. Despite presence of several analytical methods for acrylamide determination, these techniques still require further development. After review of this chapter...
Numerous studies have been performed on the conversion of individual types of waste into activated carbon (AC). However, this study focused on the evaluation of the simultaneous conversion of different types of wastes (palm, paper, and plastic...
Wastes must be managed properly to avoid negative impacts that may result. Open burning
of waste causes air pollution which is particularly hazardous. Flies, mosquitoes and rats are
major problems in poorly managed surroundings. Uncollected wastes...
The widespread use of pesticides leads to considerable attention for pesticide detection and removal.
Therefore, in the first part of this work, a simple and facile solid phase extraction (SPE) procedure for
separation of malathion from soil and...
Ultra performance liquid chromatography coupled to mass spectrometry was used for the simultaneous
separation and determination of reducing monosaccharides (fructose and glucose), a non-reducing disaccharide
(sucrose) and oligosaccharides (kestose...
