Special Issue Information

Dear Colleagues,

Foodborne diseases pose considerable threats to human health and hinder sustainable economic and social development. More than 250 foodborne illnesses have been identified worldwide, and most of them are caused by foodborne pathogens and related bacterial toxins. The rapid and sensitive detection of foodborne pathogens is essential in controlling food safety. Recently, various emerging strategies and techniques have been developed for monitoring the presence of pathogens and related bacterial toxins in food, thereby accelerating food safety assurance. Compared with traditional analytical methods, these emerging strategies and techniques provide more advantages with respect to the detecting speed, high throughput, sensitivity, robustness, portability, user friendliness, and accessibility. Thus, this Special Issue aims to emphasize the latest developments of these emerging strategies and techniques and their potentials in detecting diverse foodborne pathogens. In short, we hope this Special Issue can help researchers to understand the current status and future improvements in this field.

Deoxynivalenol (DON) contamination in germs and germ oil is posing a serious threat to food and feed security. However, the transformation pathway, the distribution of DON, and its degradation products in edible oil refining have not yet been reported in detail. In this work, we systematically explored the variation of DON in maize germ oil during refining and demonstrated that the DON in germ oil can be effectively removed by refining, during which a part of DON was transferred to the wastes, and another section of DON was degraded during degumming and alkali refining. Moreover, the DON degradation product was identified to be norDON B by using the ultraviolet absorption spectrum, high-performance liquid chromatography (HPLC), ultra-high-performance liquid chromatography-quadrupole time-of-flight mass spectrometry (UPLC-Q-TOF MS), and nuclear magnetic resonance (NMR) methods, and the degradation product was found to be distributed in waste products during oil refining. This study provides a scientific basis and useful reference for the production of non-mycotoxins edible oil by traditional refining. Full article
