Summary: Ilex paraguariensis, a native tree from South America, is known for its bioactive compounds and its leaves are consumed as hot and cold infusions after a series of processing steps including harvest, flame blanching, drying, and milling. The study investigated the impact of processing on leaf composition by extracting major compounds using different solvent ratios. The solvent ratio EW 50:50 was found to be more effective in extracting chlorogenic acids. The successful extraction of chlorogenic acids from I. paraguariensis proved its promising potential beyond traditional use.

Summary: The study evaluated the rhizogenic capacity of yerba mate mini-cuttings from different genotypes and found that while the anatomical features and root development were similar, there were significant differences in rooting performance and related growth characteristics. Despite variations in biochemical features such as POD, PPO, and PC activities/content, these did not directly impact the overall rooting performance of the mini-cuttings.

Summary: This study compared ultrasound-assisted extraction (UAE) and conventional extraction by agitation (AE) for total phenolic compounds (TPC) extraction from yerba mate leaves. Water and 50% aqueous ethanol solution were used as solvents, and the effects of solvent-to-solid ratio, particle size, stirring speed (AE), and ultrasound power amplitude (UAE) were examined. The experimental data were fitted well by the swelling/diffusion model, which considers two mechanisms coupled at different rates. The results provide valuable information for the industrial production of TPC from yerba mate leaves.

Summary: This study optimized phenolic compound extraction conditions in black quinoa seeds using Response Surface Methodology. The total phenolic content (TPC) was significantly affected by time, temperature, and sample-to-solvent ratio, with optimal conditions resulting in TPC values of 280.25 mg GAE 100g(-1) and 236.37 mg GAE 100g(-1) for different extraction mixtures. The phenolic profile of extracts obtained at optimal conditions was analyzed by HPLC, revealing differences in extraction yield but not in specificity for phenolic compounds between the two extraction procedures.

Summary: The combination of soybean grain and yerba mate as an antioxidant source can increase PUFA concentration and reduce oxidation in milk from lactating ewes reared in tropical pastures. However, soybean supplementation decreases lamb birth weight while improving the FA profile of milk by increasing CLA and PUFA concentrations. Yerba mate supplementation does not affect the oxidative profile of milk.

Summary: This study aimed to construct a dispersive optical spectrometer using 3D design software and printing without optical adjustments, and successfully validated and applied it to quantify ethanol in multiproduct liquids. The spectrometer design was achieved by using a 3D design software to design a NIR spectrometer in the desired wavelength range, followed by printing the components on a 3D printer. Results demonstrated the feasibility and accuracy of the 3D-printed spectrometer for ethanol quantification, showing comparable predictive capabilities to commercial instruments.

Summary: This study conducted the first screening of 22 Citrus cultivars in a semi-arid tropical region based on their phytochemical and polyphenolic features, using multivariate chemometric analysis. The results showed that citric acid was the dominant organic acid, glucose and fructose were the major sugars, hesperidin was the predominant flavonoid in all Citrus, and naringin was the major polyphenol in pomelos. The findings suggest that phenolic profiles can be used for authentication of Citrus samples based on their origin and can potentially be applied to other fruits as well.

Summary: In this study, physical mixtures of Nb2O5•nH(2)O and NbOPO4 were prepared to investigate the role of phosphate groups in total acidity and two reactions involving carbohydrate biomass. The acid and catalytic properties were influenced by phosphate group enrichment. The presence of Bronsted sites on the surface favored inulin conversion and NbOPO4 exhibited the best hydrolysis activity with glucose/fructose formation. Additionally, a catalyst with a more phosphated surface showed reduced deactivation during the dehydration of fructose/glucose into HMF.

Summary: This study investigated the use of dehydration combined with near-infrared spectroscopy for predicting sucrose, glucose, and fructose in sugarcane juice. Dehydrated sugarcane juice showed better predictive performance in PLS models compared to liquid sugarcane juice, with the benchtop instrument outperforming the portable instrument. The results suggest that removing water and concentrating analytes through dehydration can significantly improve the predictability of NIR-based PLS models for sugars in sugarcane juice.

Summary: This work presents the analysis of micro-, meso-, and macro-porous carbon electrodes in a symmetrical supercapacitor filled with a 1.0 M TEABF(4) EC-DMC electrolyte. The results show that activated carbon (AC) is the most suitable electrode material due to its high specific capacitance and energy. Raman spectroscopy analysis reveals that AC experiences shifts in the D- and G-bands due to electrostatic ionic adsorption in narrow pores. Graphite, though having enough specific capacitance for competitive application, has a reduced overall surface area. Graphite's Raman analysis shows BF4- insertion into graphene layers. Overall, this study demonstrates that in-situ electrochemistry and Raman spectroscopy combined can provide important information on the energy storage process in supercapacitors.

Summary: Ilex paraguariensis, a species native to Brazil, Paraguay, and Argentina, is highly valued for its positive effects on human health. The mate processing involves pre-drying, drying, and milling stages. Thermal and mass balance analysis of industrial mate processing units revealed that energy consumption in sapeco and drying operations exceeded the required calorific input. This highlights the need for optimizing energy consumption by adjusting temperature management during sapeco and drying stages, resulting in cost reduction and improved mate product quality.
