The study evaluated the adsorption potential of modified chitosan for several contaminants and found that under specific conditions, it showed good adsorption performance.
Emerging contaminants (ECs) have been studied extensively because of the various damages they can cause to the environment, especially due to the non-treated domestic effluents, which contaminate the water bodies. Therefore, it is important to evaluate alternatives to remove these compounds. The objective of this work was to evaluate the potential of a new biosorbent from chitosan modified with vanillin (CTSV) to remove isoniazid, cortisol, bisphenol A, 17 alpha-ethinylestradiol, and triclosan by competitive adsorption studies. Structural characterization of the biosorbents was performed by Fourier transform infrared spectroscopy, thermogravimetry, Brunauer-Emmett-Teller, zeta potential, scanning electron microscopy, and H-1 nuclear magnetic resonance. The adsorption for ECs were carried out in an aqueous medium, and quantitative analyzes were performed by HPLC. The effect of pH was evaluated in the pH range 5 to 10 and indicated that better results were found in pH 9 and 8 for CTS and CTSV, respectively. The salt concentrations effect was evaluated in 0.0 to 1.0 mol L-1 and revealed better adsorption conditions in 0.7 mol L-1 of NaCl. The adsorption kinetics pointed to an equilibrium condition reached quickly (with adjustment of data R-2 > 0.969) with adequacy to pseudo-second-order model for both biosorbents and ECs. The linear isothermal model was suitable for the adsorption isothermal data and distribution constant (K-D) showed the highest values for 17 alpha-ethinylestradiol (0.067 L g(-1)) and triclosan (0.197 L g(-1)) in CTSV adsorption. Thus, the results indicated that CTSV performed well in removal for the tested ECs, being an interesting alternative, due to the ease of obtaining and abundance of reagents employed in its preparation.

Summary: The recovery of phenolic antioxidants from agro-industrial by-products using non-conventional techniques is an effective approach to explore the bioactive potential of natural sources. This study found that ultra-turrax, ultrasonic bath, and pressurized liquid extraction are the most suitable methods for phenolic extraction from guava's pulp and processing waste. The extracts obtained have high antioxidant capacity and several compounds were discovered for the first time in the fruit.

Chemical profile of craft brewer's spent yeast and its antioxidant and antiproliferative activities

Priscila Aparecida Horn, Ana Lucia Bertarello Zeni, Natalia Cavichioli, Evelyn Winter, Keila Zaniboni Siqueira Batista, Luciano Vitali, Eduardo Alves de Almeida

Summary: This study characterized the chemical composition of brewer's spent yeast (BSY) from two different beer productions and tested its cytotoxicity in various cell lineages. The results showed that BSY samples had similar lipid and ash content but slight differences in other nutritional components. BSY2 sample had higher concentrations of glucans and phenolic compounds. Both BSY1 and BSY2 extracts demonstrated similar antioxidant capacity and were not cytotoxic to most cell lines except PANC-1 cells. These findings suggest that brewery residue can be a value-added functional food with potential adjuvant role against PANC-1 cell lines.

Summary: The rise in consumption of ultra-processed meat and dietary collagen supplements poses a challenge to food quality control. This study aimed to develop a new method using cyclodextrin-assisted electrokinetic chromatography with indirect UV detection to determine 4-hydroxyproline for collagen monitoring in dietary supplements and meat products. The method involved hydrolyzing samples with sulfuric acid and removing them using simultaneous neutralization/precipitation reactions with strontium carbonate. The method was successfully validated and proved to be a feasible alternative for quality control.
