What Is Glutamine Transaminase?
Glutamine Transaminase (TGase), also known as transglutaminase, is a metalloenzyme that catalyzes the formation of isopeptide bonds between glutamine and lysine residues in proteins. This enzyme facilitates protein cross-linking, resulting in modified protein structures. TGase is sourced from microorganisms such as Streptoverticillium mobaraense, animal tissues, and plants. Known for its high specificity, strong efficiency, and broad adaptability to pH and temperature, TGase is effective across a wide range of conditions.
Applications of TGase Enzyme in Meat
TGase plays a key role in meat processing by cross-linking meat proteins, which binds fragmented meat (such as ham and meatballs), enhancing shape stability and reducing waste. It improves water-holding capacity, minimizing juice loss during cooking while preserving the tender texture of the product. Additionally, TGase enables the development of low-fat meat products by forming protein matrices that replace fat. This process helps retain meat flavor, improves product uniformity, extends shelf life, and reduces production costs, making it essential for quality optimization and efficiency improvement in industrial meat processing.
How It Works in Meat Products
TGase catalyzes the formation of isopeptide bonds between glutamine and lysine residues in meat proteins, creating protein cross-links that strengthen the meat matrix. This process enhances chewiness, moisture retention, and product consistency, while also reducing cooking losses. It ensures a more stable texture and a natural flavor profile, making it ideal for improving the overall quality of processed meat products.
