“…For initial adsorption within 5 min, it increased rapidly because the active sites for MB are empty. After 1 hr, its adsorption became gradually a plateau and reached equilibrium due to the reduction of available sites [29]. The removal percentages were found to be 91.37 ± 1.94%, 96.27 ± 0.17%, and 90.18 ± 2.09% for the sponge from RS, CC, and CH, respectively, at an initial MB concentration (C 0 ) of 50 mg/L.…”

“…6(b). The adsorption mechanism of dye on the cellulose and chitosan matrix is usually proposed via the hydrogen bonding interaction between the hydroxyl (-OH) groups of the cellulose and chitosan with the nitrogen-containing groups of the MB dye [29]. Furthermore, the Langmuir and Freundlich isotherms were chosen to study equilibrium MB adsorption by the sponges (Eqs.…”

To enhance the environmental sustainability, the transformation of wastes to be useful aspects have been focused with more attention. In this study, cellulose from residue crops was extracted via microwave-assisted method and fabricated as cellulose/chitosan composite sponges for dye removal. The pore structures with good physical property were introduced via UV crosslinking without heat treatment and followed by freeze-drying method. The optimal crosslinking parameters such as plant types (rice straw, coconut coir, and corn husk), photo-catalyst types (TiO2 and sodium hypophosphite (SHP)), and UV irradiation time were performed. The results showed that cellulose derived from coconut coir with SHP under 15 min of UV exposure exhibited the porosity more than 90% and pore size in the range of 100–120 µm. The dye adsorption was fitted well with the Langmuir isotherm and provided the highest adsorption capacity at 99.01 mg/g with removal percentages of 96.27 ± 0.17% at an initial dye concentration of 50 mg/L. Thus, the low temperature and non-toxicity of the proposed method in this work has potential for converting wastes into value-added products.

“…Whey protein, a by-product of cheese production, contains various components like α-lactalbumin, β-lactoglobulin, serum albumin, lactoperoxidase, immunoglobulins, and lactoferrin, endowing it with high nutritional value [ 11 , 12 ]. When combined with substances like bee waxes, ascorbic acid, and cysteine, whey protein concentrate has proven effective in mitigating browning in fresh-cut apples.…”

In this work, smart edible coating and films with excellent UV barrier properties were prepared from alginate, whey protein isolate, and curcumin. The primary focus of this investigation centered on assessing the impact of whey protein and curcumin on the physical and functional properties of the alginate films. Whey protein reduced the film transparency while simultaneously enhancing the hydrophobicity and antioxidant properties of the alginate film. Curcumin imparted a yellow hue to the film, consequently decreasing the transparency of the film. It also substantially improved hydrophobicity, antioxidant activity, and UV-blocking efficiency within the films. Remarkably, curcumin demonstrated a significant reduction in the water vapor transmission rate of the film. For the preservation of apples, a higher concentration of curcumin was required, which effectively suppressed the respiration rate and moisture loss post-harvest, resulting in an extended shelf-life for the apples. As a result, the coated apples exhibited significantly reduced enzymatic browning and weight loss in comparison to their uncoated counterparts. Furthermore, these curcumin-containing films underwent a reversible color change from orange to red when exposed to ammonia vapor. This attribute highlights the potential of the developed coating and film as a smart, active food packaging solution, particularly for light-sensitive food products.
