Product Introduction
Shaanxi Zhenhuacui Biotechnology produces Bulk Hydrolyzed Whey Protein Isolate Powder using sophisticated enzymatic hydrolysis and thorough purification. Our product has ≥80% Whey Peptides and improved molecular weight distribution below 5,000 Daltons for better bioavailability. This cosmetic-grade formulation is an off-white powder with excellent solubility throughout pH 3.0-7.0, manufactured in cGMP and FSSC22000 facilities. We ensure uniform peptide profiles for demanding commercial formulations with consistent Degree of Hydrolysis (DH) measurements validated by OPA techniques after 10 years of extraction competence and 8 years in protein technology.

Controlled enzymatic breakdown of Bulk Hydrolyzed Whey Protein Isolate Powder produces 2,000–5,000 Daltons of short-chain peptides. These pre-digestions provide free amino acids and di-/tri-peptides without stomach breakdown. The product has complete essential amino acid profiles and a PDCAAS score of 1.0 with nitrogen concentration above 80%.

Multiple product forms can use this component.
Sports Nutrition: Instant amino acid delivery post-workout smoothies, intra-workout drinks, and recovery formulas.
Clinical Nutrition: Enteral feeding solutions, geriatric supplements, and digestive health products for gastric patients.
Functional foods: Foods with heat-stable protein, such as bars, drinks, and snacks.
Cosmetic Applications: Small peptide-enhanced anti-aging serums, hair care, and skin healing formulations.
Infant nutrition: Hypoallergenic formulations for sensitive populations.

Faster Absorption: Peptides enter the circulation in 15-30 minutes vs 60-90 minutes for full proteins.
Reduced Allergenicity: ELISA shows low intact casein fractions, making it lactose-sensitive.
Excellent Solubility: Stable in acidic and high-temperature processing (UHT support up to 140°C).
Improved muscle recovery: Insulinotropic response speeds glycogen resynthesis by 40% over regular isolates.
Can be used as capsules, tablets, gummies, solid beverages, and pressed confectionery without precipitation.
For formulation development, our 60% R&D team provides full technical support. Flexible MOQ from 1kg and testing samples are available. We have enough to ship conventional orders in 10 days and bespoke solutions in 20. Urgent orders are expedited in 7-10 days using green channel.
Our over a decade of extraction experience ensures quality from raw material to packaging. In foreign markets, cGMP, FSSC22000, ISO9001, HACCP, HALAL, KOSHER, and Organic facilities ensure compliance. OEM/ODM services let you build your brand with customized specs.

Our factories have cGMP, FSSC22000, ISO9001, HACCP, HALAL, KOSHER, and Organic Certification. These certifications guaranty your supply chain fulfills strict North American, European, and Asian-Pacific regulations.

Each batch is analytically tested:
The OPA and TNBS methods confirm peptide consistency within 15-30% DH.
SEC-HPLC verifies peptide distribution with 70% below 5,000 Daltons.
Sensory Profiling: QDA examines bitter peptide profiles for palatability.
Ensured microbial safety with <3,000 CFU/g Aerobic Plate Count and no tolerance for E. coli, Salmonella, or Cronobacter sakazaki
ICP-MS testing keeps Arsenic, Lead, Cadmium, and Mercury below 10 ppm.
HPLC validates protease inactivation, avoiding post-production hydrolysis.
Certificates of Analysis accompany each shipment, documenting protein content, DH percentage, molecular weight distribution, heavy metal results, microbial counts, and sensory evaluation scores. Ask for third-party lab verification.
For product integrity, 25kg fiber drums with double food-grade PE liner bags are standard. OEM package sizes are customizable. DHL, FedEx, and SF Express guaranty temperature-controlled transportation. Stored below 25°C in sealed containers out of direct sunlight, products last 24 months.


Our researchers developed enzymatic hydrolysis procedures to recover 92% peptides while keeping amino acid profiles. Lately, pH-neutral processing has reduced salt by 35% and proprietary enzyme blends have reduced bitter peptide production. Zero deterioration following six freeze-thaw cycles and bioactivity after UHT processing at 138°C for 4 seconds are confirmed by stability experiments.

Fi Asia is where we showcase protein hydrolysate technology advances. The platforms connect formulators and distributors seeking premium functional ingredients.

Q: What distinguishes hydrolyzed whey isolate from ordinary isolate?
A: Enzymatic pre-digestion breaks protein into smaller peptides, allowing absorption in 15 minutes versus 60+ for intact proteins.
Q: What is your 500kg order lead time?
A: Standard standards ship in 10 days from stock; bespoke formulas take 20.
