Premium Zein Peptides from Corn – High-Solubility Bioactive Peptides for Nutraceutical & Functional Food Innovation
Xi'an Jiayuan Bio-tech Co., Ltd., established in 2002 with over 20 years of expertise, specializes in producing high-quality Zein Peptides derived from corn gluten meal. Our product has high protein content ≥70% with molecular weight mostly in the range of 200-1000 Daltons and thus ensures excellent water solubility across pH 2-10 and excellent bioavailability. Our quality is stable, with 30 competent technical staff and two GMP-approved manufacturing lines, and we are ISO9001, SGS, and HALAL certified. Our solutions include >85% small-molecule peptides (<1000 Da), high Leucine content (>15%) with demonstrated hepatoprotective effect and are suitable for functional drinks, sports nutrition and bioactive delivery methods.
What Is Zein Peptides?
The products are advanced bioactive protein hydrolysates, produced by controlled enzymatic hydrolysis of Zein, the major storage protein in maize. The peptides are treated with particular proteases to cleave the molecular chains, unlike natural Zein that is insoluble in water and confined to industrial coatings.
This technique significantly boosts water solubility while preserving the distinctive amino acid profile rich in Leucine, Proline and Glutamic Acid. The end product is a highly bioavailable, plant-based substance that overcomes usual digestive restrictions
These peptides solve key formulation difficulties like low solubility of plant proteins, harsh taste profiles and lack of functional bioactivity. Because of their tiny molecular makeup (200-1000 Da) they are rapidly absorbed and are superior to traditional intact plant proteins.

Functions
Our products provide numerous verified bioactive activities for your product development:
Hepatoprotective Activity : Research has shown that it activates the enzymes alcohol dehydrogenase (ADH) and aldehyde dehydrogenase (ALDH) to speed up the metabolism of alcohol and protect liver cells from oxidative stress.
Muscle Protein Synthesis The peptides are >15% leucine and activate mTOR pathways critical to muscle healing and development, much as dairy-based sources.
Antioxidant Capacity: Hydrophobic amino acid composition offers a high free radical scavenging action, protecting the cells from oxidative damage.
ACE-Inhibitory Effects: Some peptide sequences provide cardiovascular advantages by maintaining appropriate blood pressure levels via the inhibition of angiotensin-converting enzyme.
Enhanced Bioavailability: The oligopeptide structure is absorbed directly in the intestine without additional digestion, therefore guaranteeing optimal nutrient usage in your formulations.
Application Fields
Hepatoprotective Functional Beverages: Leverage the established alcohol metabolism acceleration to provide premium hangover treatment shots and liver health beverages. The peptides are stable in clear solutions, therefore they are ideal for RTD drinks since there are no sedimentation problems.
Sports Nutrition Formulations: Stomach woes? Plant-based sources of BCAAs for vegan athletes. Our high Leucine products provide hypoallergenic muscle repair assistance in protein shakes, recovery bars and intra-workout liquids.
Nano-Encapsulation Systems: Exploit self-assembly capabilities for sensitive bioactives protection (curcumin, omega-3s, vitamins, etc.). The peptides build protective bio-films for regulated release and better stability in complicated food matrices.
Clear Label Beverages: Respond to customer demand for clear ingredient declarations with this naturally-derived, water-soluble protein source that won’t cloud functional drinks and wellness shots.

FAQ
Q: How does the solubility of the products compare to native Zein?
A: Native Zein requires alcohol-water mixtures or high pH for solubility. Our peptides are fully water-soluble over a wide pH range (2-10) due to enzymatic cleavage exposing polar groups and reducing chain length.
Q: Are the products suitable for 'Clear Label' beverages?
A: Absolutely. Proper filtering results in clear to slightly opalescent solutions and their stability in functional waters and RTD drinks is not associated with sedimentation problems.
Q: What's the main taste problem with the product?
A: Hydrophobic amino acids may cause bitterness. However, our controlled enzymatic hydrolysis by selected peptidases restricts the generation of bitter peptides. Premium lots contain a faint nutty taste that is readily concealed in recipes.
Q: Does Zein Peptide content have Gluten?
A: Zein, or 'Corn Gluten' is physiologically different from wheat gluten (gliadin/glutenin) and does not cause Celiac problems. We manufacture to avoid cross contamination with allergic grains.
Q: How do you verify the hepatoprotective activity?
A: We validate functional efficacy through in vitro assays measuring ADH and ALDH enzyme activation rates, supplemented by third-party in vivo studies demonstrating reduced blood alcohol concentration in animal models.
