Food adulteration has a long history in human society, and it still occurs in modern times. Because children are relatively vulnerable to food adulterants, studying the health impacts of food adulteration on children is important. This article provides an overview of the child health impacts of food adulterants in two recent food adulteration incidents in the Greater China Region: (1) a plasticizer incident in Taiwan and (2) a 2,4,6-triamino-1,3,5-triazine (melamine)-tainted milk incident in China. The involved food adulterants, di-(2-ethylhexyl) phthalate (DEHP), diisononyl phthalate (DiNP) and melamine, are harmful to the hippocampus, kidneys, reproductive organs and immune system of children, and they also increase the risk of cancer. To detect food adulteration and to avoid further harm caused by food adulteration, simple screening methods have been developed, and they have recently emerged as a new focus area for research. This article also summarizes the simple screening methods used to analyse the aforementioned food adulterants and reports how governments reacted to the recent food incidents. © 2017 Society of Chemical Industry.

“…There are at least several mechanisms: cation exchange interaction, hydrophilic interaction, hydrogen bonding, and target‐specific recognition (e.g., by molecularly imprinted materials). Cation exchange interaction was regarded to be the main mechanism for MEL retention on the commercially available sorbents and attapulgite nanoparticles . The molecularly imprinted materials, including MIPs, molecularly imprinted layer‐coated microspheres/films/magnetic particles, were prepared with MEL and/or its analogs as template(s), showing specific recognition for these compounds.…”

The analysis of melamine and its analogs is of increasing research interest. Owing to their high nitrogen content and low price, they were deliberately added to artificially enhance protein concentration in a number of different types of human and animal food sources. In addition, environmental water might also be contaminated by melamine due to its use in the chemical industry and the degradation of the pesticide cyromazine. Herein we provide a detailed overview of recently developed materials and techniques for the analysis of melamine and its analogs in complex matrices, especially in dairy products (e.g., milk and powdered milk) and environmental water.

“…The volume of liquid in the flask was brought up to 25 mL by adding 5% trichloroacetic acid in water. 16 An aliquot (5.0 mL) of the extract was transferred into a glass tube, to which was then added purified water (5.0 mL). This mixture was vortexed and then used for the extraction of MEL according to the procedure described in the Extraction procedure section.…”

“…Soc. 1658 extraction, 15 surface enhanced Raman spectroscopy, 16 capillary zone electrophoresis-mass spectrum (CE-MS), 17 electrochemical methods, 18 surface plasmon resonance, 19 and fluorescence immunosensor 20 have been employed for the determination of melamine. However, some of these methods require tedious pretreatment of samples, have low levels of detection, consume large amounts of organic solvents, use reagents that are not commercially available, and use expensive equipment.…”

In this work, for the first time, a highly sensitive method based on dispersive liquid-liquid microextraction coupled with positive corona discharge ion mobility spectrometry as a fast and inexpensive technique has been evaluated for the direct determination of melamine. The effective parameters influencing the microextraction efficiency, such as pH, the properties of extraction and dispersion solvent were investigated. Under the optimum conditions, analytical parameters such as linearity, precision and limit of detection were evaluated. The calibration graph of melamine determination using the proposed method has two regions of linearity from 0.5 to 70 ng mL -1 and 70 to 1500 ng mL -1 , the limit of detection and limit of quantification are 0.25 and 0.5 ng mL -1 , respectively, and the relative standard deviation was less than 3% for all experiments. The proposed method was successfully applied for the determination of melamine in the milk, dairy products and egg yolk.
