Characterization of Benitaka Grape Pomace (Vitis vinifera L.): An Analysis of Its Properties for Future Biorefinery Applications

Waste, Journal Year: 2025, Volume and Issue: 3(1), P. 4 - 4

Published: Jan. 9, 2025

This study investigates the properties of Benitaka grape pomace (Vitis vinifera L.), a byproduct wine industry, focusing on its potential for applications in circular economy and biorefinery processes. The analysis covers range physical, chemical, structural characteristics, including composition proteins, moisture, lipids, ash, sugars, fiber fractions (such as neutral-detergent fiber, cellulose, lignin, hemicellulose), pH, acidity, gross energy, well bioactive compounds such total phenolics, flavonoids, anthocyanins, antioxidant capacity. Advanced characterization techniques, nitrogen adsorption/desorption isotherms, Fourier-transform infrared spectroscopy, differential scanning calorimetry, electron microscopy, high-performance liquid chromatography coupled with mass spectrometry, were employed. results revealed an acidic pH 4.05 titratable acidity 1.25 g tartaric acid per 100 g. energy was 3764 kcal kg−1, indicating high capacity, similar to wood chips. exhibited hygroscopicity (31 50 moisture g), levels significant values phenolics (5956.56 mg GAE g−1), flavonoids (1958.33 CAT anthocyanins (66.92 C3G g−1). Antioxidant showed promising results, DPPH FRAP 20.12 16.85 μmol TEAC g−1 extract, respectively. not only validates existing data but also provides new insights into hemicellulose lignocellulosic phase transitions, highlighting resource sustainability industry

Multi-Analytical Approach for the Acid-Base, Thermal and Surface Properties Assessment of Waste Biomasses

Molecules, Journal Year: 2024, Volume and Issue: 29(23), P. 5735 - 5735

Published: Dec. 5, 2024

A multi-analytical approach was used to comprehensively characterize the acid-base, thermal, and surface properties of agri-food processing wastes (i.e., original pre-treated bergamot, grape olive pomaces). These biomasses, often underutilised inadequately studied in terms their physicochemical properties, were investigated under varying ionic strength conditions at
