Summary: In this study, cellulose nanofibers (CNFs) were prepared from wood and used to treat fresh-cut apple wedges. The CNF treatment significantly improved the appearance, reduced the decay rate, and delayed the deterioration of apple wedges during storage. Gas chromatography-mass spectrometry analysis showed that CNF treatment maintained the aroma components of apple wedges. Further investigations revealed that CNF treatment enhanced the antioxidant system and reduced oxidative damage in apple wedges. Overall, CNF coating effectively maintained the quality of fresh-cut apples during cold storage.

Summary: In this study, bacterial cellulose nanofibers (BCNs) were used as nanofillers to prepare gelatin-based edible films. The addition of BCNs improved the crystallinity, thermal stability, mechanical properties, and barrier performance of the films. Moreover, the fresh-keeping performance of the gelatin-based coating on fresh-cut apples was also enhanced by BCNs, especially at a content of 2%. Therefore, BCNs show promising potential for application in the food preservation field.

Summary: The cut or sliced form of apples is more vulnerable to chemical deterioration and microbial growth. This study investigated the quality changes and microbial safety of fresh-cut apples stored at 4 degrees C for 15 days after different immersion treatments. Carvacrol emulsions based on whey protein isolate/high methoxyl pectin effectively delayed browning and improved the chemical quality consistency. Furthermore, the presence of carvacrol emulsions reduced viable bacteria and yeast and mold growth during storage. Carvacrol emulsions have the potential to be an alternative preservation method for fresh-cut apples.

Summary: The combination of encapsulated L. plantarum and eugenol was more effective in inhibiting browning and passing consumer panel tests than when used separately. The application of encapsulated L. plantarum and eugenol maintained the physicochemical qualities of the samples and improved the antioxidant enzyme activity. After 15 days of storage at 4 degrees C, the growth of L. plantarum in samples treated with encapsulated L. plantarum and eugenol was reduced by only 1.72 log CFU/g. These findings suggest that the combination of encapsulated L. plantarum and eugenol is a promising method for preserving the appearance and protecting fresh-cut apples from food-borne pathogens.

Summary: Fresh-cut apples have gained popularity due to their health benefits and convenience. However, the main challenge in processing these apples is the rapid browning that occurs after cutting. This review provides an overview of the characteristics of polyphenol oxidase (PPO) in apples and the development of antibrowning compounds. It also highlights the need for further research in this area.

Summary: This study investigated the effects of different temperatures on the physicochemical and microstructural properties of myofibrillary protein supplemented with glucose and cellulose nanofibers. The results showed that glucose and cellulose nanofibers could cross-link with myofibrillary protein through non-covalent bonds, leading to changes in the structure and properties of myofibrillary protein. The particle size and hydrophobicity of myofibrillary protein were found to change at different temperatures. At 121 degrees C, the addition of glucose and cellulose nanofibers prevented the loss of leucine and lysine in myofibrillary protein. Microscopic images revealed better dispersion of glucose-myofibrillary protein and cellulose nanofibers-myofibrillary protein.

Summary: The study aimed to evaluate the natural microbiota of packed fresh-cut apples during refrigerated storage. Two different films, a biodegradable (PLA) film and a conventional commercial one (OPP) were tested for packaging. Two antioxidants, a natural olive pomace extract and commercially used ascorbic acid, were applied. Results showed lower bacteria counts in samples with olive pomace extract and PLA films compared to those with ascorbic acid and OPP films after 5 and 12 days of storage. The use of natural extracts as additives in fruits could delay the growth of mesophilic bacteria.

Summary: Computer vision systems offer fast, objective, non-destructive, and contactless evaluation of fruit, and this work focuses on the identification and selection of pulp inside images of fresh-cut apples. A DeepLabV3+-based CNN model has been developed for semantic segmentation, successfully separating the pulp from the peel and achieving an accuracy greater than 99% on different varieties of apples. This approach can isolate regions affected by browning, allowing for color analysis to evaluate the internal quality and senescence of packaged and unpackaged products.

Summary: Crosslinking affects the mechanical behavior and tissue metabolism of collagen-based tissues. Aging and diabetes alter the crosslinking type and density, thus changing tissue properties. High-connectivity enzymatic crosslinking and advanced-glycation end-products result in uniform deformation under daily activity, while low-connectivity enzymatic crosslinking does not. High-connectivity model displays more sliding, while AGEs induce instability in structures near the binding sites.

Summary: The potential of multi-layer nanoemulsions for improving the cellular uptake, antioxidant activity, and in vitro bioaccessibility of alpha-tocopherol was examined. The results showed that the multi-layer nanoemulsions significantly enhanced the cellular uptake and antioxidant activity of alpha-tocopherol compared to free coumarin 6. Furthermore, the use of chitosan and dextran sulfate as wall materials in the multi-layer nanoemulsions led to even higher cellular uptake, in vitro bioaccessibility, and antioxidant activity of alpha-tocopherol.
