Summary: In this study, an antioxidant and pH-sensitive film based on arrowhead starch, kappa-carrageenan, and black chokeberry extract was developed and its physical and structural properties were investigated. The incorporation of black chokeberry extract with kappa-carrageenan and arrowhead starch significantly affected the film's properties, including light transmittance, thickness, elongation at break, and pH sensitivity. Rheological property analysis of the suspensions indicated shear-thinning behavior with high viscosity. The functional properties of the films showed strong scavenging activity on DPPH free radical and color changes in response to chicken wing qualities, suggesting their potential application in active and intelligent food packaging.

Summary: Red raspberries, rich in nutrients and phytochemicals, can be used to create supplements. This study investigated the production of micronized raspberry powders and analyzed their molecular characteristics, sugar content, and biological potential. The results showed that micronization broke the intramolecular hydrogen bonds, increasing the content of simple sugars and phenolic compounds. Micronized powders had higher concentrations of ellagic acid derivatives and rutin, and exhibited increased antioxidant activity.

Summary: This study developed an eco-friendly food packaging material using regenerated cellulose films with the addition of grape seed extract (GSE) and polyethylene glycol 200 (PEG). The composite film showed improved mechanical properties, water contact angle, UV-blocking properties, and exhibited color changes under different pH conditions. Furthermore, the addition of GSE delayed the decomposition and biodegradation of strawberries. This research demonstrates the potential of regenerated cellulose film as a color sensor in 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.
