The incorporation of leafy vegetables into meat products offers a promising strategy for enhancing nutritional value and shelf-life while reducing reliance on synthetic additives. This study evaluated the substitution of lamb (Edilbaev breed) with spinach (0%, 10%, 20%, and 30%) in meat dumplings to assess effects on composition, functionality, microbial stability, lipid oxidation, and sensory quality. Spinach addition enriched the products with minerals, vitamins, and dietary fiber while moderating fat and protein content. Functional properties such as water- and fat-binding capacity were improved, contributing to lower cooking losses, and microbiological tests confirmed slower proliferation of spoilage organisms during chilled storage. Moreover, spinach components contributed to improved oxidative stability, as evidenced by lower thiobarbituric acid values and reduced acid numbers, indicating slower lipid oxidation and hydrolysis. Sensory evaluation revealed that substitution up to 20% maintained favorable appearance, texture, and taste, while higher levels diminished acceptability. Overall, incorporating spinach at a 20% substitution level provides an optimal balance of nutritional enhancement, functional performance, microbial and oxidative stability, and sensory acceptance, making it a practical approach for developing healthier lamb-based dumplings with strong potential for consumer acceptance and market application.
