Summary: In this research, pH-sensitive films were prepared using purple-fleshed sweet potato starch and sweet potato peel, and commercial purple sweet potato anthocyanin was incorporated into the films. The addition of anthocyanin resulted in increased thickness, water solubility, and swelling degree, as well as decreased tensile strength and tensile modulus but increased elongation at break of the films. The films showed the fastest color migration in acidic conditions and successfully monitored chicken freshness.

Summary: This study demonstrates the effectiveness of a single-layer coating using chitosan and sodium alginate solutions in improving the storage qualities and shelf-life of fresh-cut purple-flesh sweet potatoes. The coating reduces microbial proliferation, color change, and weight loss, while retaining the total anthocyanin content and total phenolic content of the sweet potatoes. Uncoated samples showed quality deterioration over time.

Summary: A new method was developed to prepare color-changeable smart packaging films based on cooked purple sweet potato. Steaming and boiling treatments were beneficial to retain anthocyanins in purple sweet potato, while uncooked and roasting treatments were detrimental to maintain the stability of anthocyanins. The films prepared from steamed and boiled purple sweet potato had better microstructures, higher crystallinity, stronger barrier ability, mechanical property, thermal stability, antioxidant activity, and pH-/ammonia-sensitivity.

Summary: Due to their intrinsic structural characteristics and natural renewability, biomass materials are increasingly used as attractive components in energy storage devices. In this study, purple sweet potato is used as the carbon source and activated with KOH and Zn(OAC)(2).2H(2)O to create a carbon material with a rich pore structure and large surface area. When assembled as a cathode in a Li-S battery with sulfur infiltration, the resulting battery exhibits a high discharge capacity of 1390 mA h g(-1), excellent rate performance, cycling stability, and environmental friendliness due to the use of sustainable biomass precursors.

Summary: Purple sweet potato is a main food crop abundant in anthocyanins, starches, non-starch polysaccharides, caffeoylquinic acid derivatives, vitamins and minerals. Anthocyanins in purple sweet potato have potential applications in food, cosmetics and pharmaceuticals due to their heat resistance and ultraviolet stability. Additionally, they have been found to possess various health-promoting activities such as antioxidant, anti-inflammatory, anticancer, hypouricemic, hepatoprotective, hypolipidemic, hypoglycemic, and neuroprotective effects. This review summarizes recent advances on the health-promoting activities of purple sweet potato anthocyanins, providing a theoretical basis for the development of functional foods.

Summary: A pH-sensitive film based on sodium alginate, gelatin, and plum peel extract (SGPE) was developed to monitor the freshness of chicken. The addition of plum peel extract improved the film's internal structure and mechanical property, while reducing water contact angle, water content, and water vapor transmission. The SGPE15 film showed a stronger pH sensitivity and successfully indicated the freshness deterioration of chicken breast flesh on day 6.

Summary: In this study, biosorbent beads immobilized with banana, orange, and potato peels were used for the biosorption of heavy metals from a cocktail solution. The beads exhibited significant biosorption capacity for As and Pb, but decreased significantly for Cd, Cu, Hg, and Ni ions at basic pH values in drinking water conditions. The effectiveness of biosorption was influenced by the surface heterogeneity and concentration of the biosorbent beads, with banana peel beads showing the highest biosorption efficiency.

Summary: Purple sweet potato (PSP) powder can reduce oxidative stress and inflammation. A study developed an animal model of high fat diet (HFD)-induced dry eye disease (DED) and found that adding 5% PSP powder to the diet mitigated the effects of HFD-induced DED by preserving lacrimal gland (LG) function and structure. The PSP treatment regulated oxidative stress and lipid homeostasis in the LG.

Summary: The objective of this research was to develop a pH-sensitive packaging using sodium alginate (SA) and apricot peel pectin (APP) with rose anthocyanins extracts (RAEs) for monitoring grass carp fish meat freshness. The incorporation of RAEs in the composite films improved thermal stability, antioxidant capacity, and light barrier behaviors. The film containing 20% RAEs showed remarkable sensitivity to pH changes and had potential for grass carp freshness monitoring.

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.
