Summary: Squid chitosan nanoparticles (SCNs) were prepared as a biofungicide against citrus fungal pathogens. In vitro tests showed that 200 ppm concentration of SCNs completely inhibited the growth of three fungi. In vivo studies demonstrated that 250 ppm SCNs treatment effectively suppressed fruit disease symptoms.

Summary: Chitosan, derived from shrimp waste, has a range of applications in various fields due to its physicochemical properties and antibacterial activities. This study compared the effects of different extraction methods on the properties and antibacterial activity of chitosan. The results showed that conventional extraction produced high molecular weight chitosan with the highest yield, while microwave-assisted extraction yielded medium molecular weight chitosan. The chitosan extracted using the conventional method showed the best antibacterial activity against the target bacteria.

Summary: The study analyzed the multi-element composition of rare earth elements (REE) in surface sediment from the Devi river estuary on the eastern coast of India. The sediments are primarily derived from the Eastern Ghat Group of rocks and are influenced by intrinsic physicochemical parameters, mainly salinity and redox conditions.

Summary: The development of effective and economic ion-exchange membranes is crucial for the widely studied process of reverse electrodialysis (RED) which collects salinity gradient energy from mixing seawater and river water. This study focuses on the design and development of anion exchange membranes, specifically synthesizing and benchmarking homogeneous AEMs based on different types of polyepichlorohydrin (PECH). The results show that PECH-C-based anion-exchange membranes exhibit a higher power density in a lab-scale RED system, indicating potential for energy generation.

Summary: A film with colorimetric, fluorescent and active functions was developed using chitosan and polyvinyl alcohol as the film matrix and curcumin-ss-cyclodextrin complex as the freshness indicator for pork and shrimp. The film not only prolongs shelf life, but also undergoes color and fluorescence changes during storage. the incorporation of PVA enhances the mechanical properties of the film, while Cur-ss-CD improves its antioxidant and antibacterial properties, water contact angle and water vapor permeability. These results demonstrate the potential of this film as an intelligent and active food packaging material.

Summary: The study revealed differences in microstructural and chemical properties between neon flying squid (OB) and jumbo squid (DG) mantles after frozen storage. Jumbo squid showed better stability in myofibrillar protein (MP) content compared to neon flying squid. Label-free proteomic analysis identified various differentially abundant proteins (DAPs) in the mantles of both species, with some proteins improving the stability of jumbo squid in response to freezing-induced changes.

Summary: This study investigated the impact of beta-chitin micro- and nanoparticles derived from jumbo squid pens on the water vapor permeability of PVA/CS films. Addition of NPs significantly increased tensile strength and elongation percentage of the films, while WVP values did not change significantly among different PVA/CS proportions but were significantly lower in the second period.

Summary: Physical carrageenan/chitosan hydrogels were prepared by electrostatic complexation between the two oppositely charged polysaccharides. The addition of chitosan acted as a crosslinker and enhanced the mechanical properties of the hydrogels. The resulting composite hydrogels showed potential for applications in drug delivery, tissue engineering, and bone regeneration.

Summary: The cryoprotective effect of collagen hydrolysates from squid skin (CH-SS) on shrimp muscle during freeze-thaw cycles was investigated. Antifreeze peptides (AFPs) in CH-SS were separated and identified. CH-SS showed inhibitory effect on myofibrillar protein denaturation and structural changes, and retained the water binding ability. SEM analysis revealed that CH-SS effectively reduced mechanical injury caused by ice crystals. The fraction from CH-SS obtained through Sephadex G-25 chromatography had the highest antifreeze activity, with amino acid sequence identified as DVRGAEGSAGL by UPLC-MS analysis. This study provides a theoretical basis for intensive processing of squid skin and development of new antifreeze agents.

Summary: The study found that the inclusion of aloe vera altered the color parameters, barrier properties, and mechanical properties of the films. While the concentration of aloe vera did not significantly change film properties, it did increase the stability of the films at lower temperatures. This suggests a crosslinking/complexation between chitosan and aloe vera, providing suitable properties for wound dressing materials.

Summary: Squid pen chitooligosaccharide (COS) at 400 ppm combined with oxygen-based modified atmospheric packaging (MAP) effectively reduced metmyoglobin formation, maintained redness of slices, and prolonged shelf-life at 4℃ for 9 days. Argon-based MAP did not show positive effects on quality retention of tuna slices.

Summary: This study identified and characterized three types of AQPs in Litopenaeus vannamei and investigated their potential roles in osmoregulation. The expression levels of AQPs were significantly decreased under salinity stress, though the patterns varied among isoforms and tissues. Comparative transcriptome analysis revealed the involvement of aquaglyceroporin and amino acid metabolism related genes and pathways in the response to acute salinity changes in the intestine.

Summary: Air-cushion (AC) packaging can be used as an effective microalgal photobioreactor (PBR), addressing operational issues encountered with traditional open raceway ponds and closed photobioreactors. The study showed that using ACs can lead to high biomass and lipid productivity in microalgae cultivation.
