Summary: This research developed corn starch/chitosan nanoparticles/thymol bio-nanocomposite films as potential food packaging materials to prolong food shelf life. Thymol addition increased water vapor permeability but decreased tensile strength and other mechanical properties of the films. The 3% thymol bio-nanocomposite films showed the most promising performance in extending the shelf life of cherry tomatoes.

Summary: Poly(butylene adipate-co-terephthalate) (PBAT), starch, plasticizer, and tea polyphenols (TP) were synthesized into masterbatches without pre-dispersion and then blown into active films to reduce TP degradation. TP had strong interaction with starch through hydrogen bonds, but little interaction with PBAT. Incorporating TP improved barrier properties but slightly decreased mechanical properties of the films. The short-term degradation of the starch/PBAT film was slowed down by TP, while the long-term degradation was accelerated. The high retention and stability of TP in active films make them suitable for industrial development of active packaging materials.

Summary: This article proposes a method using supercritical carbon dioxide (scCO(2)) to obtain compostable bionanocomposite foams based on PLA and organoclay. The foams showed a closed cell and uniform cell structure with enhanced thermal stability and improved overall mechanical performance. The water uptake behavior demonstrated that the foams had low water absorption, and they also disintegrated under composting conditions. Therefore, these bionanocomposite foams seem to be a promising sustainable alternative for applications such as food packaging.

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.
