Hydrolyzed Soy Protein Powder
Description
Hydrolyzed Soy Protein Powder – Plant-Based Peptide Solution for Nutrition, Cosmetics & Hair Care Applications
Xi'an Le-Nutra Ingredients Inc is a leading supplier of premium-grade Hydrolyzed Soy Protein Powder (protein content≥80%, average molecular weight regulated at ≤2,000 Daltons). Our enzymatically processed soy peptide is produced in our 60,000㎡ GMP-certified plant with a capacity of 3,000 tonnes per year and features excellent solubility, fast absorption and multi-industry adaptability.

Boasting over 14 years of experience in plant protein hydrolysis technology and having rigorous quality control procedures that guarantee heavy metals <1ppm and pathogen negative results, we provide reliable batches to nutritional supplement makers, cosmetic formulators and pet nutrition brands in global markets.
What Makes Our Hydrolyzed Soy Protein Powder Different?
This plant-based protein derivative is obtained by precise enzymatic hydrolysis of non-GMO soybeans from Northeast Africa. The controlled hydrolysis process decomposes long-chain polypeptides into bioactive peptides and free amino acids.
Our production technology addresses three major formulation difficulties. First, it addresses the solubility problems of native soy proteins at acidic pH values (3.0-4.5). Secondly, peptide cleavage depletes allergenic protein fractions while retaining nutritional integrity. Third, the optimised molecular weight distribution can be directly taken up by cells without extensive digestion procedures.

The resulting yellow fine powder dissolves to crystal clear solutions from pale yellow to pale amber. This transparency works well for transparent serums, transparent beverage formulations and clean-label supplement items where visual clarity is important.

Core Functional Benefits Across Applications
Quantifiable performance gains in formulation development are derived from the bioactive peptides found in our hydrolysed soy protein.
For Nutritional Supplements: The oligopeptide structure (≤2,000 Da) guarantees fast intestine absorption, without the need of enzymatic digestion. This makes it more suitable for post workout recovery formulations and clinical nutrition solutions for damaged digestive systems. Provides a comprehensive necessary amino acid profile to enhance muscle synthesis, immunological function and metabolic balance.
For Cosmetic Formulations: Small molecular peptides can enter the stratum corneum effectively, providing moisture retention and collagen production stimulation. The anti-oxidant capabilities counteract oxidative stress signals while the anti-inflammatory peptides prevent skin irritation in sensitive formulations.
For Hair Care Products: The protein fragments bind to damaged keratin structures in hair cuticles, healing surface damage and increasing tensile strength. Formulators report improved shine, smoothness and manageability in shampoos, conditioners and leave-in treatments at 2-5% active concentration.
For Pet Nutrition: The hypoallergenic profile and digestibility makes it valuable for veterinary diets addressing food allergies. The cholesterol-free formula helps cardiovascular health in elderly pet formulas.
Industrial Production Process & Quality Assurance
We manufacture using pharmaceutical grade standards and six crucial check points.
Stage 1 – Raw Material Selection: We procure our identity-preserved soybeans with certified non-GMO certification and do inbound inspections for mycotoxins and pesticide residues.
Stage 2 – Protein Isolation: Sophisticated aqueous extraction to eliminate lipids and anti-nutritional substances, while retaining native protein structures. Defatting decreases the lipid level to <1% and inhibits rancidity and oxidation during storage.
Stage 3 – Enzymatic Hydrolysis: Enzymatic treatment at regulated temperature (particular protease systems) and controlled pH settings, to break the peptide bonds. Real-time sampling keeps the degree of hydrolysis (DH) in specification limits for the desired molecular weights.
Stage 4 – Purification: Multi-stage filtration eliminates enzyme residues, salts and unhydrolyzed fractions. This procedure is important to obtain the transparent dissolution profile required for beverage and cosmetic applications.
Stage 5 – Spray Drying: Low temperature spray drying protects heat labile peptides and brings the moisture to the desirable level (≤5.0%). Particle size distribution optimised for fast reconstitution.
Stage 6 – Quality Testing: Every batch of product is rigorously tested using HPLC molecular weight mapping, Kjeldahl nitrogen analysis, ICP-MS heavy metal testing and full microbiological testing. Each shipment will be provided with COA, TDS, MSDS and third party test results.

FAQ
Q: Hydrolysed soy protein is mostly suited to which product categories?
A: Suitable for cosmetics (essence, lotion, cream), hair care products (shampoo, conditioner, hair mask), oral supplements (protein powder, solid drinks) and pet nutrition supplies. In the hair care industry, it may be efficiently repaired damaged hair cuticles, boost the lustre and smoothness.
Q: What does your product offer in terms of features and purity? How does it stack up against the competition?
A: We use non-GMO soybeans from Northeast Africa. The processing is enzymatic and under careful control. The protein concentration is ≥80%, which is a high purity level. It is cheaper and more favourable to vegetarian diets than collagen. It offers great cost effectiveness and is lactose and cholesterol free as compared to whey protein.
Q: What colour and clarity does the aqueous solution of the hydrolysed soy protein take on following dilution?
A: After disintegration it is clean and transparent, without any sediment or impurity. The solution colour is between light yellow and pale amber, and can be used in transparent product applications such as translucent essence liquids and clear beverages.
Q: How is having an average molecular weight of 2,000 Daltons useful in practice?
A: This molecular weight is within that of oligopeptides which are rapidly absorbed with excellent bioavailability and good penetration in cosmetics, directly absorbed without digestion in oral products and dissolving quickly in cold water so easy to handle.
Q: What are the industrial production processes and key quality inspection items?
A: The process is pre-treatment → degreasing → enzymatic hydrolysis → purification → drying → packaging. The key control factors are the enzymatic hydrolysis temperature and pH. For each batch, the protein content, molecular weight, heavy metals (less than 1ppm), aflatoxin, and microorganisms (Salmonella/E. coli negative) are tested. A complete COA is provided with the goods.
Q: How long is the delivery period? Is customization supported?
A: Customization of molecular weight, packaging specifications and physical parameters is supported.
