Special Issue Information

Dear Colleagues,

Chemical contaminants may occur in foods from various sources, such as use of agrochemicals, environment pollution, food processing, food packaging and natural toxins, as well as adulterating. They impact food quality seriously and typically pose a health concern. The investigation of these contaminants is very important for controlling them in foods and ensuring consumer health.

The aim of this Special Issue is to publish high-quality research articles, as well as reviews that seek to address recent developments relating contaminants, their detection methods, formation mechanisms and routes of food polluttion, as well as control strategy.

Potential topics include, but are not limited to:

  • Pesticides, veterinary drug and herbicides, as well as plant growth regulators, their detection methods and food pollution routes;
  • Heavy metal pollution and their effects on food quality;
  • Endocrine disruptors derived from environment pollution, their detection and pollution behavior in foods;
  • Effects of food processing, especially thermal processing on the formation of contaminants;
  • Safety management of hazardous substances produced during food processing;
  • Contaminants migrated from food packaging;
  • Natural toxins from edible plants and animal foods, their removal or deactivation;

Food adulteration identification and authenticity evaluation.

2-Monochloropropane-1, 3-diol (2-MCPD) esters and 3-monochloropropane-1,2-diol (3-MCPD) esters, a class of substances potentially harmful to human health, are usually formed during the refining of vegetable oils under high temperature.

2-Monochloropropane-1, 3-diol (2-MCPD) esters and 3-monochloropropane-1,2-diol (3-MCPD) esters, a class of substances potentially harmful to human health, are usually formed during the refining of vegetable oils under high temperature. The effects of endogenous antioxidants in vegetable oils on the formation of 2- and 3-MCPD esters is still unknown. In this study, the effects of endogenous antioxidants (α-tocopherol, stigmasterol and squalene) on the formation of 2- and 3-MCPD esters in model thermal processing of camellia oil were investigated. The possible formation mechanism of 2- and 3-MCPD esters was also studied through the monitoring of acyloxonium ions, the intermediate ions of 2- and 3-MCPD esters formation, and free radicals by employing infrared spectra and electron paramagnetic resonance (EPR), respectively. The results indicated that the addition of α-tocopherol had either promoting or inhibiting effects on the formation of 2- and 3-MCPD esters, depending on the amount added. Stigmasterol inhibited the formation of 3-MCPD ester and 2-MCPD ester at low concentrations, while promoting their formation at high concentrations. Squalene exhibited a promotional effect on the formation of 3-MCPD ester and 2-MCPD ester, with an increased promotion effect as the amount of squalene added increased. The EPR results suggested that CCl3•, Lipid alkoxyl, N3• and SO3• formed during the processing of camellia oil, which may further mediate the formation of chlorpropanol esters. This study also inferred that squalene promotes the participation of the free radical in chlorpropanol ester formation. Full article
