“…The –OH groups of water absorbed around 3300 cm −1 , while the –COH bond present in starch was observed at frequencies of 912 cm −1 [ 18 ]. Other vibrations were observed in the regions between 1012 cm −1 and 1164 cm −1 , attributed to the C–O–C groups of polysaccharides [ 39 ]. Furthermore, the vibration range around 497 cm −1 is characteristic of the Zn-O bond of inorganic nanomaterial, as presented in our previous study [ 24 ].…”

In this work, novel nanocomposite films based on babassu coconut mesocarp and zinc oxide nanoparticles (ZnO NPs), synthesized by a green route, were produced for application as food packaging films. The films were prepared using the casting method containing different contents of ZnO NPs (0 wt%, 0.1 wt%, 0.5 wt%, and 1.0 wt%). The films were characterized by Fourier-transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), thermogravimetric analysis (TGA), scanning electron microscopy (SEM), instrumental color analysis, and optical properties. The water vapor permeability (WVP) and tensile strength of films were also determined. The antimicrobial activity of the films against cooked turkey ham samples contaminated with Staphylococcus aureus was investigated. The results showed that incorporating ZnO NPs into babassu mesocarp matrices influenced the structure of the biopolymer chains and the color of the films. The BM/ZnO-0.5 film (0.5 wt% ZnO NPs) showed better thermal, mechanical, and WVP properties. Furthermore, the synergistic effect of babassu mesocarp and ZnO NPs in the BM/ZnO-0.5 film improved the antimicrobial properties of the material, reducing the microbial count of S. aureus in cooked turkey ham samples stored under refrigeration for 7 days. Thus, the films produced in this study showed promising antimicrobial packaging materials for processed foods.

“…The TH was produced in the Interdisciplinary Laboratory of Advanced Materials (LI-MAV) of the Federal University of Piaui. The test hydrogel was used as recommended according to the characteristics found in the study conducted by [11], who produced hydrogel based on natural fiber from babassu mesocarp (plant scientific name Orbignya pharelata), different from the test hydrogel in this experiment, which was produced with fiber obtained from cashew gum (plant scientific name Anacardium occidentale L.). In the chemical analysis of the cashew gum hydrogel, the authors concluded that the material demonstrated good swelling capacity in consecutive cycles.…”

Hydrogels are water-absorbing polymers that can hydrate forage plants in the soil. The objective was to evaluate the replacement of synthetic hydrogels derived from petroleum with biodegradable hydrogels in Mombaça grass pastures (Megathyrsus maximum). The experimental treatments consisted of no hydrogel (NH); synthetic commercial hydrogel (CH), made from a synthetic polyacrylamide product; and biodegradable test hydrogel (TH), obtained from cashew gum (Anacardium occidentale). The experimental design consisted of randomized blocks with five replications and three treatments. The morphogenesis, production, chemical, and mineral composition of the Mombaça grass pasture were assessed. The data were subjected to analysis of variance and mean comparison using the Scott–Knott test at 5% probability. The leaf elongation rate showed 42.3 mm day−1 in the treatment TH, which was higher (p < 0.05) than NH (35.0 mm day−1). The green leaf mass yield was higher in TH than in NH and CH. On the other hand, hydration had no effect on the chemical composition. The mineral composition of Mombaça grass showed more Zn when TH was used. It can be concluded that biodegradable hydrogels can replace synthetic commercial hydrogels in pastures.

“…The use of hydrogel ensures moisture retention in the soil, increasing water availability for plants (Saha et al, 2020;Sousa et al, 2023;Edvan et al, 2023), being a promising strategy to be used in the production of plants of agronomic interest in arid regions, as it enhances the germination process and initial development of crops (Ai et al, 2020). In sandy textured soil under saline conditions, Costa et al (2022) found that the use of hydrogel polymer reduced water loss by 58%.…”

The use of cactus pear has shown poor performance in some areas of semi-arid climate regions, as the species needs a wide gradient between temperatures during the day and night to develop, which does not occur in such zones. To lessen this negative occurrence, moisture availability provides better performance for the species, such as using hydrogel instead of irrigation. The objective of this study was to evaluate the effect of using hydrogel polymers on the production of cactus pear (Opuntia stricta cv. Mexican Elephant Ear). Three treatments with six replications were used, totalling 18 experimental units. The treatments were, (1) Conventional fertilization using fertilizer in granulated format; (2) Foliar fertilization with polymer using a dilution dose of 6 grams of polymer L-1 of water associated with the fertilizer in liquid form through the foliar route; (3) Foliar fertilization without polymer using only foliar fertilization in the same formulation as the treatment with polymer. There was no effect of fertilization strategy on plant height, cladode length, cladode width, cladode thickness, cladode area, and biomass. There was an effect of the fertilization strategy on dry matter, in which higher estimates were measured for conventional fertilization and foliar fertilization without polymer. On the other hand, foliar fertilization with polymer promoted increases of 13% in mineral matter and 42% in crude protein in relation to conventional fertilization. The fertilization strategy did not change the other chemical attributes of cactus pear. The use of the hydrogel did not influence the morphometric development of the Mexican Elephant Ear cultivar but promoted increments in the chemical composition.
