Growing consumer demand for healthier meat products with clean-label ingredients has increased interest in plant-based fortification strategies. The present study evaluated the effects of a multicomponent cereal supplement comprising rice (35%), buckwheat (20%), oats (20%), and corn (25%) on the physicochemical, functional, oxidative, hydrolytic, and sensory properties of meat patties. Four formulations were prepared with 0% (control), 5%, 10%, and 15% supplement inclusion. At higher inclusion levels of the cereal supplement, the patties showed reduced moisture, protein, and fat contents, while ash and carbohydrate levels increased. Conversely, ash content increased from 1.38% to 2.82%, and carbohydrates rose to 8.99%. pH remained stable (5.92–6.04), whereas aw decreased significantly at 10% (0.921) and 15% (0.889) inclusion (p < 0.05). Functional tests showed dose-dependent improvements in water-binding capacity, which increased from 65.98% in the control to 71.58% at 10% supplement, and in fat retention, which rose from 38.3% to 54.14% under the same conditions, with optimal performance observed at 10% inclusion. TBARS values in 10% and 15% formulations were 13–20% lower than control throughout storage (p < 0.05). The increase in acid number was significantly slower in supplemented patties, indicating that the cereal blend effectively inhibited lipid hydrolysis during storage. Sensory evaluation revealed maximal acceptability at 10% inclusion, with declines at 15% due to grainy texture and flavor dilution. These findings establish 10% multicomponent cereal supplementation as a promising strategy to enhance yield, shelf-life stability, and consumer appeal of meat patties without compromising processing parameters.
