Polycyclic aromatic hydrocarbons (PAHs) are ubiquitous in the air, oils, water, and food products we encounter every day. Among these exposures, food consumption is a major route of PAH exposure for nonsmokers. The PAH dietary exposure levels vary among different countries; however, many studies have shown PAH exposure to be highly concerning to human health. The levels of PAH contamination in food are mainly influenced by processing procedures and cooking methods, and they could be attenuated by modifying cooking procedures and adding antioxidant‐rich marinades. Several PAHs have toxic, mutagenic, and carcinogenic properties. The PAH benzo[a]pyrene (BaP) is particularly regarded as carcinogenic. There are three major metabolism pathways for PAHs, and the final products can bind to DNA, thus exerting mutagenic effects. Biological monitoring through the use of biomarkers is necessary for comprehensive and accurate risk assessments of human PAH exposure. It is important to reduce dietary PAH exposure and to implement reasonable and effective risk management strategies to reduce PAH levels in food to improve public health.

Cyclodextrin is an odorless and tasteless cyclic oligosaccharide widely used in various fields such as food, medicine and the environment. Cyclodextrin can improve solubility and stability, and can mask the bad taste of specific substances. Cyclodextrins and their polymers primarily act by forming complexes in foods, and can be applied in food packing, food analysis, enhancing the properties of antioxidants, antibacterials, for stability and so on. The challenges and opportunities facing this area are reviewed. It is hoped that the review will provide useful information for future applications of cyclodextrin in the food industry.

“…In applications other than pippete‐tip microextraction, ILs and PILs have been combined with magnetic‐based sorbent materials such as α‐Fe 3 O 4 MNPs [28,29] or magnetic modified chitosan‐graphene oxide composite [30]. The objective of these studies was to perform magnetic separation of the sorbent material after dispersive μ‐SPE extraction/desorption.…”

Ionic liquids and derivatives-mainly polymeric ionic liquids and magnetic ionic liquids-have been extensively used in microscale extraction over the past few years. Current trends in analytical sample preparation gear toward linking microextraction approaches with high-throughput sample processing to comply with green analytical chemistry requirements. A variety of high sample throughput strategies that are coupled to both ionic-liquid-based solid-phase microextraction and ionic liquid-based liquid-phase microextraction are herein reported. The review is focused on microscale extraction methods that use (i) custom-made and dedicated extraction devices, (ii) parallel extraction, (iii) magnetic-based separation, and (iv) miniaturized systems employing semi-automatic or fully automatic flow injection methods, related micro/millifluidic devices, and robotic equipment.
