Description
N-acetyl-l-tyrosine is a white to off-white crystalline powder, odorless or with a slightly characteristic odor. N-acetyl-l-tyrosine is slightly soluble in water and readily soluble in alkaline solutions or organic solvents (such as ethanol).
Advantages:
Enhanced stability: Acetylation protects the amino group, reduces oxidative degradation, and extends the shelf life of food.
High bioavailability: N-acetyl-L-tyrosine is more easily absorbed than free tyrosine and provides amino acid resources rapidly.
Functional activity retention: N-acetyl-L-tyrosine, as a tyrosine precursor, participates in the synthesis of neurotransmitters (such as dopamine and epinephrine).
Antioxidant property: The phenolic hydroxyl structure can eliminate free radicals and assist food in antioxidation.

Application
Nutritional fortifier
N-acetyl-l-tyrosine supplements essential amino acids and is particularly suitable for protein-fortified foods. N-acetyl-l-tyrosine is added to protein powder and energy bars to support muscle repair and nerve function. N-acetyl-l-tyrosine is used in postoperative recovery, food for people under stress, to improve cognition and fight fatigue.
Antioxidants and stabilizers
N-acetyl-l-tyrosine delays fat oxidation and protects the color and flavor of food. N-acetyl-l-tyrosine is added to high-fat milk powder or cheese to inhibit rancidity. N-acetyl-l-tyrosine reduces lipid peroxidation in processed meat and extends the shelf life.
Flavor improvement and functional beverages
N-acetyl-l-tyrosine, as a stable component in alkaline solutions, enhances the functionality of beverages. N-acetyl-l-tyrosine works in synergy with caffeine and B vitamins to enhance the refreshing effect.
Processing aid
N-acetyl-l-tyrosine serves as a nitrogen source in fermented foods to promote microbial growth. Production optimization of fermented condiments such as N-acetyl-L-tyrosine soy sauce.
