This interest has driven the development of functional diets and nutraceutical foods, which, in addition to nourishing, offer therapeutic benefits such as improving the immune system and gut health.Nutraceutical ingredients contain nutrients and bioactive molecules such as antioxidants and anti-inflammatory compounds, which enhance their efficacy in improving health. These ingredients can be obtaining through the use of the biotechnological strategies, and the valorization of by-products obtain from the agri-food industry. This combine strategy enhance the efficiency of the process and more sustainable. The milling industry generates large quantities of by-products, mainly bran from cereals such as wheat and oats, which are a rich source of fibre and bioactive compounds. Strategies employed include the use of hydrolytic enzymes and grain germination, techniques that improve the bioaccessibility of active compounds.The main objective of this thesis was to develop a nutraceutical ingredient from wheat and oat bran and grains, focused on reducing oxidative stress and inflammation associated with metabolic syndrome. Enzymatic hydrolysis and germination processes were applied, obtaining ingredients rich in ferulic acid and β-glucan, which possess antioxidant and immunomodulatory properties.The results of the studies indicated that the combination of wheat and oat ingredients improves antioxidant and anti-inflammatory properties, enhancing their efficacy. Furthermore, bioaccessibility assessment using dynamic in vitro models demonstrated enhanced antioxidant capacity compared to static methods. These findings suggest that the nutraceutical ingredients developed have great potential in the prevention of metabolic syndrome-related diseases.
