In the food science field, the term "antimicrobial" basically refers to active substances of synthetic or natural origin, that are directly or indirectly present in a specific food, packaging material or food contact surface that affect the viability or the growth of microorganisms in that matrix [...].

In order to improve the preservation of red grape fruits, 'Chuju' polysaccharides (CCP) were cross-linked with chitosan (CS) to create CCP/CS composites with varying ratios. These composites were comprehensively characterized using FT-IR, C NMR, and SEM, which confirmed a smooth film surface and a uniform distribution of CCP. The composite films demonstrated efficacy in maintaining the quality of red grapes by mitigating shriveling and significantly reducing firmness loss by 22.

Inspired by the superhydrophobic characteristics of duck feathers this research introduced an intelligent, responsive, and eco-friendly food packaging film constructed from carboxymethyl cellulose (CMC) and gelatin (Gel). The film successfully mimics the asymmetric, bionic, barbed structure of a duck feather, offering outstanding hydrophobicity and moisture vapor resistance characteristics. Moreover, the bionic film demonstrated good mechanical strength, film-forming ability and biodegradability.

A colorimetric-fluorescence ripeness indicator, based on copper nanoparticles and carbon quantum dots doped with nitrogen (CuNPs/N@CQD) immobilized in agar hydrogel (AGH-CuNPs/N@CQDs) for ethylene gas detection, was developed for detecting the ripening of bananas. Ethylene could reduce the fluorescence intensity of CuNPs/N@CQDs and cause a red shift of the LSPR peak. The prepared AGH-CuNPs/N@CQDs indicator had an irreversible response to ethylene with LOD and LOQ of 9.

The formation of histamine in food is influenced by temperature, and histamine growth can be inhibited by maintaining a cold chain. However, simply relying on temperature control is insufficient, as certain bacteria can produce the enzyme histidine decarboxylase even at temperatures below 5°C. To address this issue, various methods, such as modified atmosphere packaging, high hydrostatic pressure, and irradiation, have been developed to control histamine in fishery products.

The goal of this study was to characterize the microbial profile of two different fresh pork cuts, bootjack (BJ) trim and tenderloin (TL), through a 16S rRNA sequencing workflow developed specifically for investigating low-biomass fresh meat within a commercial production schedule. Additionally, this study aimed to determine a baseline prevalence and enumeration profile across these two fresh pork cuts. Results showed that microbiome diversity was different between the BJ and TL, and also differed significantly by processing date.
