Abstract
Potato oxidized hydroxypropyl starch (POHS)/pectin (P) functional and smart beef freshness indicator films were prepared using butterfly pea (Clitoria ternatea) anthocyanin (BA) and silver nanoparticles (AgNPs). BA exhibited significant pH-responsive color changes. BA and AgNPs were evenly distributed within a polymer matrix to create a compatible film with POHS/P. The films containing BA and AgNPs had good UV resistance and maintained strong mechanical strength, barrier properties, and color stability. The color of the indicator film changed from purple to green when exposed to ammonia, with the 1 % POHS/P/BA/AgNPs film showing the most sensitive response. The films also demonstrated strong antibacterial and antioxidant properties. The freshness of beef was monitored using 1 % POHS/P/BA/AgNPs films and was identified as sub-fresh and spoiled on days 4 and 7, respectively. The relationship between the color change of the indicator label and the freshness of chilled beef was established: purple for fresh meat, blue for less fresh meat, and green for spoiled meat. Thus, the new POHS/P/BA/AgNPs film can serve as a smart packaging material to indicate food freshness and extend shelf life. These results suggest that POHS/P/BA/AgNPs films have significant potential as an active and smart food packaging material.

Beyond brewing: β-acid rich hop extract in the development of a multifunctional polylactic acid-based food packaging. Int J Biol Macromol 2023; 228:23-39. [PMID: 36565824 DOI: 10.1016/j.ijbiomac.2022.12.191] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/25/2022] [Revised: 12/08/2022] [Accepted: 12/17/2022] [Indexed: 12/24/2022]
Abstract
Hops' (Humulus lupulus L.) phytochemicals are well known for their bioactivity. In the present study, the functional properties of hop extract rich in β-acids, as potassium-salts structures (KBA), were investigated to develop a sustainable active food packaging. Polylactic acid (PLA)-based sheets were incorporated with increasing concentrations of hop extract (0.1-5 % w/w in terms of KBA) and characterized through performance and bioactive properties. KBA-added sheets presented decreased crystallinity and affected mechanical and thermal properties, especially with higher KBA amounts. The sheets' surface hydrophobicity gradually decreased by KBA-extract addition, while the water vapor permeability was not affected. A Fickian diffuse behavior and a better fit to application in fatty foods were observed during release tests. UV-blocking and antioxidant properties were improved by KBA incorporation. Furthermore, results from antibacterial assays revealed great susceptibility of Staphylococcus aureus and Listeria monocytogenes towards sheets added with 5 % of KBA. Moreover, the atomic force microscopy (AFM) observations revealed that KBA led to strong effects on the cell membranes of both bacteria, including disruption of membrane integrity and cell death. Therefore, this study is a sign of great prospects of hop β-acids use, as KBA compound, in the production of sustainable active packaging for safe food shelf-life extension.

Antimicrobial mechanism of linalool against Brochothrix thermosphacta and its application on chilled beef. Food Res Int 2022; 157:111407.

Abstract
This work aimed to explore the antibacterial ability and potential mechanism of linalool against Brochothrix thermosphacta (B. thermosphacta), providing knowledge of the preservation of chilled beef with linalool. The results found that linalool had an encouraging inhibitory effect on B. thermosphacta with a minimum inhibitory concentration (MIC) of 1.5 mL/L. Results of FESEM and zeta potential combined with probe labeling confirmed that linalool destroyed the cell structure thereby causing the leakage of intracellular components (AKP, protein, nucleic acid and ion). In addition, linalool caused respiratory disturbance by measuring the key enzyme activities including PK, SDH, MDH and ATPase. Energy limitation also appeared under linalool stress as seen from changes in ATP content (decreased by 56.06% and 69.24% in MIC and 2MIC groups, respectively). The respiratory inhibition rate of linalool to B. thermosphacta was 23.58% and the superposing rate with malonic acid was minimal (35.52%), suggesting that respiratory depression was mainly caused by the TCA cycle. Furthermore, accumulation of ROS and increase in MDA content (increased by 71.17% and 78.03% in MIC and 2MIC groups, respectively) accompanied by decreased activities of detoxification enzymes CAT and POD suggested that oxidative stress contributed to the bactericidal mechanism. Finally, linalool has been shown to effectively inhibit quality deterioration of chilled beef during storage by measuring pH, TVB-N and TVC without affecting sensory acceptability. All these highlight the great promise of using linalool as natural preservative for food industry.

Abstract
Nonsolvent-induced phase separation (NIPS) method was employed to prepare polylactic acid (PLA) films using N-methyl-2-pyrrolidone (NMP) as a nonsolvent. The morphology and structure of PLA films were characterized, and the application of the films in pork preservation was investigated. When 10 wt% NMP was added, film with uniform porous structures was obtained. The crystalline and Fourier-transform infrared spectra analyses indicated that the addition of NMP during the preparation of PLA films caused their crystalline properties to change, but had no effect on their composition. However, the 10 wt% NMP/PLA film had improved thermal stability, water vapor transmission and oxygen permeability. The results on the changes in pH, total volatile basic nitrogen content and total viable counts of pork during refrigerated storage indicated that the 10 wt% NMP/PLA film could more effectively extend the shelf life of pork than polyethylene film. This work demonstrates the potential of the porous PLA film in pork packaging.

Abstract
Pseudomonas aeruginosa (P. aeruginosa) is the dominant spoilage bacterium in cold fresh beef. The current strategy is undertaken to overcome the low water solubility of linalool by encapsulating linalool into emulsions. The results of field emission scanning electron microscopy and particle size distribution revealed that the appearance of the bacterial cells was severely disrupted after exposure to linalool emulsion (LE) with an minimum inhibitory concentration (MIC) of 1.5 mL/L. Probes combined with fluorescence spectroscopy were performed to detect cell membrane permeability, while intracellular components (protein and ion leakage) and crystal violet staining were further measured to characterize cell membrane integrity and biofilm formation ability. The results confirmed that LE could destroy the structure of the cell membrane, thereby leading to the leakage of intracellular material and effective removal of biofilms. Molecular docking confirmed that LE can interact with the flagellar cap protein (FliD) and DNA of P. aeruginosa, inhibiting biofilm formation and causing genetic damage. Furthermore, the results of respiratory metabolism and reactive oxygen species (ROS) accumulation revealed that LE could significantly inhibit the metabolic activity of P. aeruginosa and induce oxidative stress. In particular, the inhibition rate of LE on P. aeruginosa was 23.03% and inhibited mainly the tricarboxylic acid cycle (TCA). Finally, LE was applied to preserve cold fresh beef, and the results showed that LE could effectively inhibit the activity of P. aeruginosa and delay the quality change of cold fresh beef during the storage period. These results are of great significance to developing natural preservatives and extending the shelf life of cold fresh beef.

Abstract
This study aimed to evaluate the effects of super-chilled storage (-1.3 °C) combined with starch film packaging containing different contents of sea buckthorn pomace extract (SSF, 0, 1, 2, and 3%, w/w) on the quality of chilled beef. The release kinetics, microstructure, and mechanical properties of the film were also measured to investigate its suitability for super-chilled storage. The results of the meat quality assessment showed that the L*, a*, and sensory evaluation values of the SSF-3% samples were significantly higher (P < 0.05), and the pH, b*, thiobarbituric acid reactive substance (TBARS), total volatile basic nitrogen (TVB-N), and total viable count (TCA) were significantly lower (P < 0.05) than the SSF-0%. The release of SBP from the SSF film was controlled by diffusion. Furthermore, SSF-3% was found to have a compact microstructure and good mechanical properties at the end of the super-chilled storage. The results demonstrated that SSF is an effective packaging material for beef at super-chilling temperatures.
