<p>This research presents an innovative approach to valorizing beetroot pomace—a byproduct rich in bioactive compounds—by formulating nutraceutical tablets fortified with phytonutrients and antioxidants. To enhance the phytochemical content and improve the flow properties of the powder, advanced processing techniques such as ultrasonication and freeze-drying were employed. Comprehensive characterization using FTIR, SEM, and particle size distribution analysis confirmed the uniformity and high quality of the freeze-dried powder. The formulated tablets exhibited rapid disintegration and remarkable stability, retaining substantial levels of phytochemicals and antioxidant activity even after five months of storage. This study innovatively formulates nutraceutical tablets using freeze-dried Beta vulgaris L. pomace powder, characterizing their nutritional profile and identifying key phytochemicals. The process ensures maximum retention of bioactive compounds, offering a sustainable method to valorize agricultural waste into health-promoting supplements.</p>
