Special Issue Information

Dear Colleagues,

Polymeric nanomaterials, a group of nanoscale materials that can be constructed from various polymers, have been applied in a variety of fields due to their multiple functionalities. The polymers, which serve as the building blocks for the nanomaterials, can be natural, synthetic, or post-synthetic modified natural polymers. Benefiting from the structure versatilities and flexibility of polymers, effective modulation of their compositions, morphologies, sizes, and surface properties can be realized in the resultant nanomaterials, which further makes hierarchical assembly of these nanomaterials into functional components possible. Therefore, polymeric nanomaterials have great application potential in the food industry, performing various functions such as reducing nutritional loss, enhancing the functionality of bioactives, extending shelf life, and so on.

This Special Issue aims to highlight the recent advances of polymeric nanomaterials in food applications. Potential topics include, but are not limited to, (1) design and characterization of polymeric nanomaterials with potential utilization in foods; (2) polymeric nanomaterials as delivery vehicles; (3) Pickering emulsions, hydrogels, and other structures formulated using polymeric nanomaterials; (4) polymeric nanomaterials in food packaging, including smart/intelligent packaging; (5) polymeric nanomaterials used in food safety areas, such as for detection of foodborne pathogens, inhibition of biofilm formation, and so on.

Abstract
Novel hierarchical metal-organic framework/chitosan aerogel composites were developed for oil bleaching. UiO-66-COOH-type metal organic frameworks (Zr-MOFs) were synthesized and integrated onto a chitosan matrix with different contents and named MOF-aerogel-1 and MOF-aerogel-2. Due to the compatibility of chitosan, the carboxylic zirconium MOF-aerogels not [...] Read more.
Novel hierarchical metal-organic framework/chitosan aerogel composites were developed for oil bleaching. UiO-66-COOH-type metal organic frameworks (Zr-MOFs) were synthesized and integrated onto a chitosan matrix with different contents and named MOF-aerogel-1 and MOF-aerogel-2. Due to the compatibility of chitosan, the carboxylic zirconium MOF-aerogels not only maintained the inherent chemical accessibility of UiO-66-COOH, but the unique crystallization and structural characteristics of these MOF nanoparticles were also preserved. Through 3-dimensional reconstructed images, aggregation of the UiO-66-COOH particles was observed in MOF-aerogel-1, while the MOF was homogeneously distributed on the surface of the chitosan lamellae in MOF-aerogel-2. All aerogels, with or without immobilized MOF nanoparticles, were capable of removing carotenoids during oil bleaching. MOF-aerogel-2 showed the most satisfying removal proportions of 26.6%, 36.5%, and 47.2% at 50 °C, 75 °C, and 100 °C, respectively, and its performance was very similar to that of commercial activated clay. The reuse performance of MOF-aerogel-2 was tested, and the results showed its exceptional sustainability for carotenoid removal. These findings suggested the effectiveness of the MOFaerogel for potential utilization in oil bleaching treatments. Full article
