How to extract egg white hydrolysate ovalbumin albumin peptide powder?
2026-05-14
As times evolve, consumers are no longer satisfied with ordinary protein powders, instead, they are seeking albumin peptide products with high bioavailability. For companies in the supplement and nutritional product industries, Kintainutri®provides production processes and manufacturing techniques for Albumin Peptides with a purity of90%–99%, unlocking their powerful potential.
What is the difference between protein powder and albumin peptide?
The fundamental difference between protein powder and albumin peptides lies in their molecular size and absorption efficiency. Protein powder consists of large-molecule proteins that must first undergo digestion and breakdown within the gastrointestinal tract before the human body can absorb them. Albumin peptide powder, conversely, are short-chain, small-molecule compounds that have already undergone enzymatic hydrolysis; they require no further digestion and can be absorbed directly and efficiently by the body.
| Aspect | Protein Powder | Albumin Peptide |
|---|---|---|
| Absorption | Large-molecule protein that requires prolonged digestion by pepsin and intestinal enzymes before absorption. | Small-molecule short-chain peptides that are absorbed directly through the intestinal mucosa into the bloodstream without digestion. Extremely fast absorption with no burden on the digestive system. |
| Composition & Function | Typically made from soy protein, casein, whey protein, pea protein, or a combination. Provides basic nutritional support by supplementing protein. | Specifically refers to active peptides derived from high-quality egg whites through targeted enzymatic hydrolysis. In addition to nutrition, they offer physiological regulatory functions (e.g., immune support, Antioxidant effects). |
| Target Audience | Suitable for healthy individuals, bodybuilders, post-surgery recovery, vegetarians/picky eaters. Long-term or excessive intake may increase metabolic burden on the liver and kidneys. | More suitable for individuals with weak digestive function (e.g., elderly, post-surgery patients with poor digestion), those with weak constitution, and people needing rapid nutrient absorption to boost immunity. |
Ovalbumin Peptide Powder Manufacturing Processes
The manufacturing process for albumin peptides employs enzymatic hydrolysis technology. Fresh liquid egg white serves as the raw material, after being mixed with deionized water at a ratio of 2:1, the mixture is preheated at 45°C for 20 minutes. Subsequently, 5% Alcalase protease is added, and the mixture undergoes enzymatic hydrolysis at 50°C and pH 6.0 for 32 hours.
Alcalase was selected as the optimal enzyme due to its superior degree of hydrolysis (43.2%) and free radical scavenging activity (82.5% at 5 mg/mL). Upon completion of the enzymatic hydrolysis, the enzymes are inactivated by heating the solution in a boiling water bath for 15 minutes. Insoluble residues are then removed via centrifugation (2,800 g for 20 minutes), and the resulting supernatant is freeze-dried to yield the final albumin peptide powder.
This process effectively converts egg white albumin into highly bioactive albumin peptides. The prepared peptides exhibit potent antioxidant activity, with an IC₅₀ value for ABTS free radical scavenging reaching 0.84 mg/mL. Furthermore, their activity is observed to increase following simulated gastrointestinal digestion, indicating that these peptides are not only rapidly absorbed but also capable of sustaining their biological activity within the body.
Benefits of Ovalbumin Albumin Peptide Powder
Albumin peptides possess potent antioxidant activity and the capacity to enhance enzymatic defense systems. They demonstrate strong free radical scavenging capabilities, effectively counteracting oxidative stress and thereby exerting anti-aging and antioxidant effects. Concurrently, they exhibit a range of additional biological functions, including blood pressure regulation, anti-inflammatory properties, and anti-obesity effects.
Most importantly, egg white hydrolysate are non-hepatotoxic and demonstrate hepatoprotective effects under conditions of metabolic stres, they can mitigate liver injury, reduce hepatic lipid accumulation, and improve triglyceride metabolism. These characteristics position our albumin peptide powder as a premium functional ingredient for use in functional foods, sports nutrition, and metabolic health products.
Applications of Ovalbumin Peptide Powder
Given the inherent bioactivity of ovalbumin peptide powder, particularly their ease of digestion and absorption, they are ideally suited for providing nutritional support to individuals with sensitive digestive systems and patients recovering from surgery. For those with allergies to dairy or soy, albumin peptide dietary supplements offer an effective alternative for meeting daily protein requirements.
Furthermore, the antioxidant properties and immune-boosting capabilities of albumin peptides contribute significantly to overall health maintenance. Supplements formulated with albumin hydrolysate powder, such as albumin peptide oral liquids and functional foods, are widely utilized within the health and wellness sector.
