“…Besides that, the amount of lipid can increase the collision frequency between droplets and coalescence rate in the polymeric matrix (Hafsa et al, 2016). The results are in agreement with the findings reported by Nouri et al (2018) where SRC + G films. It was noted that the TBARS value of 1.5 mg MDA/ kg and above showed an unacceptable off-odor for meat product (Gallego et al, 2016).…”

“…The absorption band at 2,937 cm −1 that is referred to alkane groups (C-H stretching vibrations) in the film matrix appeared when G was added into the film formulation. No band existed for the SRC-control sample which shows a good miscibility in the interaction between SRC and G in the film matrix (Nouri et al, 2018;Rhim & Wang, 2014). Moreover, the incorporation of G in the SRCbased films increased the peaks intensity compared with that of the SRC-based film without G addition (SRC-control).…”

“…All films demonstrated a broad band ranging between 3,200 and 3,600 cm −1 that is attributed to the stretching of hydroxyl (-OH) groups of carrageenan and water (Nouri, Yaraki, Ghorbanpour, & Wang, 2018;Shankar, Wang, & Rhim, 2017). The peak at 1635 cm −1 corresponds to the stretching vibration of the -NH group, a typical amide I in all SRC-based films (Rhim & Wang, 2014;Shankar et al, 2017).…”

Semi‐refined carrageenan (SRC) film plasticized with glycerol and incorporated with α‐tocopherol was prepared for food packaging application. Functional characterization, thermal stability, and microstructure of SRC‐based films were analyzed. The effects of antioxidant α‐tocopherol from SRC‐based film were studied based on thiobarbituric acid‐reactive substance assay, metmyoglobin assay, and pH value in food model (meat patties) for 12 days of storage. The development of lipid oxidation was delayed in the meat patties wrapped with antioxidant films during the storage with the final value of 0.68–0.37 mg malondialdehyde/kg sample. A less than 50% brown color development (metmyoglobin) of the meat patties wrapped with antioxidant film was observed in the first nine days of storage. Hence, the incorporation of α‐tocopherol into the SRC‐based film could be an alternative way to prolong the shelf life of food product, reducing the use of synthetic preservative directly into food product. Practical applications Recent strategy on the development of biodegradable film for food packaging is important as an alternative to the petrochemical‐derived plastic that is harmful to the environment. SRC is one of the potential biopolymers that has the ability to form a strong gel and provides efficient barrier against gas, lipids, and oils, and addition of plasticizer glycerol into SRC enhanced mechanical and barrier properties of the films. The present study showed the potential of α‐tocopherol within the SRC film plasticized with glycerol as active packaging on the film characteristics and increased the shelf life of meat patties. Hence, the active packaging film developed is not only contributes to reduce plastic waste discharged to environment but can be a potential substitute of synthetic preservative in food.

Nanocomposites made from alginate and nanoclay are extensively applied for diverse biomedical applications. However, the lack of a clear understanding of the interactions between alginate and nanoclay makes it difficult to rationally design the nanocomposites for different material extrusion‐based 3D bioprinting strategies. Here, a combined analytical model is proposed to accurately predict the interaction mechanisms between alginate and nanoclay through small‐angle neutron scattering. These mechanisms are summarized into a phase diagram that can guide the design of alginate‐nanoclay nanocomposites for different bioprinting applications. The rheological properties of various nanocomposites are measured to validate the proposed interaction mechanisms at the macroscale. Accordingly, three representative extrusion‐based bioprinting strategies are linked with the nanocomposite design and applied to freeform fabricate complex structures. A roadmap is summarized to bridge the gap between biomaterial design and bioprinting processes, enabling the rapid and rational selection of biomaterial formula based on available 3D printing methods, and vice versa.

Bacterial resistance to antibiotics is an important issue in contemporary society. To date, infection‐related problems persist despite intensive research efforts by chemists and biologists. Much effort has been devoted over the last decade to the development of organic/nonmetallic inorganic nanocompounds with antimicrobial activities for overcoming human infections and illnesses produced by antibiotic‐resistant pathogens. Both organic nanomaterials such as chitosan nanoparticles and conductive‐based polymer nanocompounds, as well as nonmetallic inorganic nanomaterials such as carbon‐based nanocompounds and modified nanoceramics, have been manufactured and employed in medicine for treating multidrug‐resistant infections. This review describes the most recent advances in the biomedical applications of antibacterial organic/nonmetallic inorganic nanocompounds.
