Walnut peptides are small-molecule functional peptides prepared from walnut protein using enzymatic hydrolysis technology. Their molecular weight is typically below 1000 Daltons. The preparation process preserves the nutritional properties of walnuts while significantly improving solubility and absorption efficiency. As a protein peptide possessing both nutritional value and bioactivity, walnut peptides exhibit unique value in neuroprotection, antioxidation, and metabolic regulation.

Neuroprotection and Cognitive Improvement: Walnut peptides are rich in neuroactive amino acids such as glutamine, which can cross the blood-brain barrier and inhibit β-amyloid protein aggregation and tau protein hyperphosphorylation. Their antioxidant properties can reduce neuronal oxidative damage, promote the expression of brain-derived neurotrophic factor, and improve learning and memory abilities.
Antioxidant and Anti-aging: The active peptides in walnut peptides can directly scavenge free radicals and enhance the activity of endogenous antioxidant enzymes such as superoxide dismutase. By protecting cell membrane and mitochondrial function, it slows down the aging process of skin and organs.
Lipid Regulation and Cardiovascular Protection: This component can inhibit intestinal cholesterol absorption and promote hepatic lipid metabolism, helping to lower serum total cholesterol and LDL cholesterol levels. Its anti-inflammatory properties help reduce vascular endothelial inflammation and improve arterial elasticity.
Immunity Enhancement and Anti-fatigue: Walnut peptides provide easily absorbed amino acids that support immune cell proliferation and antibody synthesis. By optimizing energy metabolism and reducing lactic acid accumulation, it alleviates physical and mental fatigue.
Brain Health and Anti-Aging Supplements: Dietary supplements to improve memory, concentration, and prevent cognitive decline, suitable for middle-aged and elderly people and those engaged in mental work.
Cardiovascular Health Functional Foods: Health foods used to help regulate blood lipids and maintain vascular elasticity, suitable for people at risk of hypertension and arteriosclerosis. As a post-exercise recovery supplement, it helps relieve fatigue and support metabolic balance.
Special Nutrition and Rehabilitation Support: As an easily absorbed protein source in post-operative and post-illness recovery formulas, it promotes tissue repair. Fortified foods for children and pregnant women support nervous system development.
Food Industry and Animal Nutrition: Added as a functional ingredient to beverages, dairy products, and nutrition bars to enhance product health attributes. Used in pet food or aquatic feed to improve animal cognitive function and coat quality.

For some products that require special packaging during transportation, we will carry out more delicate packaging. For example, retinal needs to be stored at -20 °C, so we choose cold chain transportation during transportation; deoxyarbutin will change color during transportation, so we will Vacuum packing of deoxyarbutin
