Whey protein CAS: 9010-10-0

What Is Whey Protein?

Our premium Whey Protein (CAS 9010-10-0) is a high-purity dairy protein concentrate that we produce from fresh, pasteurized cow’s milk through advanced membrane filtration and low-temperature spray-drying technology. This creamy-white, free-flowing powder delivers a complete amino acid profile rich in branched-chain amino acids (BCAAs) — leucine, isoleucine, and valine — which support muscle protein synthesis, post-exercise recovery, and lean muscle maintenance. Consequently, this versatile dairy ingredient serves as the gold-standard protein source for sports nutrition, functional foods, and dietary supplement manufacturers worldwide.

Moreover, our premium Whey Protein provides exceptional solubility with a clean, neutral dairy taste that blends seamlessly into shakes, bars, baked goods, and ready-to-drink beverages. Furthermore, we produce this ingredient through a cold-processing ultrafiltration method that preserves the native protein structure and bioactive peptide fractions — including lactoferrin, immunoglobulins, and glycomacropeptides. Specifically, each batch undergoes rigorous testing to verify protein content, amino acid distribution, microbial safety, and heavy metal compliance.

Technical Specifications

Natural Dairy Source: Fresh Cow’s Milk

Our premium Whey Protein originates from fresh, high-quality cow’s milk collected from dairy farms that follow strict animal welfare and feed quality protocols. Holstein and Jersey dairy cows graze on nutrient-rich pastures and receive balanced supplementary feed — a combination that yields milk with consistently high protein and minimal somatic cell counts. Following milking, the fresh milk undergoes immediate refrigeration and rapid transport to our processing facility, where pasteurization ensures microbial safety before protein fractionation begins.

Notably, whey represents the liquid fraction that separates from milk during cheese production — a co-product that we capture and refine rather than discard. Milk protein consists of approximately 80% casein and 20% whey, making this ingredient a concentrated and valuable nutritional resource. Our advanced cross-flow ultrafiltration membranes selectively retain native whey proteins while removing lactose, minerals, and water — concentrating the protein fraction without thermal denaturation. Additionally, this cold-processing approach preserves heat-sensitive bioactive components including immunoglobulins and lactoferrin that contribute to immune function. Above all, we source milk exclusively from farms certified free of recombinant bovine somatotropin (rBST), ensuring a clean, natural protein product.

Whey Protein Applications & Industry Uses

Whey Protein for Sports Nutrition & Recovery

Sports nutrition formulators rely on our premium Whey Protein as the foundational ingredient for protein powders, mass gainers, and post-workout recovery formulas. Because this ingredient digests rapidly and delivers a complete essential amino acid profile within 60–90 minutes of consumption, it triggers a robust muscle protein synthesis response — making it uniquely effective for post-exercise recovery. Specifically, the high leucine content (approximately 10–11 g per 100 g protein) directly activates the mTOR signaling pathway that drives muscle tissue repair and growth. Consequently, supplement brands worldwide build their protein product lines around this ingredient’s proven efficacy, clean taste, and excellent mixability.

Functional Foods & High-Protein Snacks

Food manufacturers increasingly use our premium Whey Protein to boost the nutritional density of everyday food products. The ingredient’s neutral flavor and smooth texture allow protein fortification of baked goods, breakfast cereals, pasta, soups, and sauces without compromising taste or mouthfeel. Moreover, protein bar and snack manufacturers depend on this versatile dairy protein for its unique combination of water-binding capacity, emulsification properties, and heat-set gelation — functional attributes that improve bar texture, extend shelf life, and prevent hardening during storage. Furthermore, clean-label brands appreciate that this single-ingredient protein requires no artificial enhancers to deliver both nutrition and functionality.

Beverages & Ready-to-Drink Formulations

Beverage manufacturers select our instantized premium Whey Protein for its exceptional dispersibility in both neutral-pH and acidified beverage systems. The instantized version dissolves rapidly in cold liquids with minimal foaming, producing clear, sediment-free protein waters and smooth, creamy protein shakes. Specifically, ready-to-drink (RTD) protein beverages, meal replacement drinks, and protein-fortified coffee beverages all benefit from this ingredient’s clean dairy taste and heat stability during UHT processing. Notably, the protein remains soluble and stable throughout the product’s shelf life, preventing the gritty sedimentation that plagues inferior protein sources. Consequently, leading beverage brands trust this ingredient for premium-positioned protein drinks that consumers enjoy daily.

Clinical & Medical Nutrition

Clinical nutrition manufacturers incorporate our premium Whey Protein into enteral feeding formulas, geriatric nutrition products, and medical food formulations. The ingredient’s high biological value (BV 104) and complete essential amino acid profile make it ideal for patients requiring enhanced protein intake during recovery from surgery, illness, or malnutrition. Additionally, the cysteine and glutamine content support glutathione synthesis — the body’s master antioxidant — and immune cell function. Specifically, oncology nutrition products, wound-healing formulas, and sarcopenia prevention supplements all benefit from the superior digestibility and amino acid composition of this carefully processed dairy protein.

Infant Formula & Pediatric Nutrition

Infant formula manufacturers use our premium Whey Protein to adjust the whey-to-casein ratio of bovine milk from approximately 20:80 to the 60:40 ratio found in human breast milk — a critical modification that improves digestibility and amino acid delivery for developing infants. Our gentle membrane filtration process preserves the native alpha-lactalbumin and lactoferrin fractions that support infant immune development and mineral absorption. Furthermore, this ingredient undergoes demineralization and extensive quality testing to meet the stringent purity standards required for infant nutrition applications.

Whey Protein Frequently Asked Questions

Q: What distinguishes your premium Whey Protein from standard WPC products?

A: Our product is a non-denatured, instantized Whey Protein Concentrate (WPC 80) produced through cold membrane filtration rather than high-heat processing. This preserves the native bioactive peptide fractions including lactoferrin, immunoglobulins, and glycomacropeptides. Every batch undergoes independent third-party verification for protein content, amino acid composition, and microbiological purity.

Q: What grades and protein concentrations do you supply?

A: We supply a comprehensive range including Whey Protein Concentrate (WPC 35, WPC 80), Whey Protein Isolate (WPI 90), and Hydrolyzed Whey Protein. Our standard bulk offering is premium Whey Protein (WPC 80) with ≥80% protein content. We can customize protein concentration, instantization level, and particle size to your requirements.

Q: Does this ingredient work for clear protein beverages?

A: Our Whey Protein Isolate (WPI 90) delivers excellent clarity in acidified beverage systems at pH 3.0–3.8. The isolate undergoes additional filtration to remove fat and lactose, producing transparent, sediment-free protein waters and clear RTD beverages. For creamy shake applications, we recommend our instantized premium Whey Protein (WPC 80).

Q: Can you provide organic or grass-fed certified versions?

A: Yes. We offer certified organic Whey Protein produced from the milk of cows raised on certified organic pastures without synthetic pesticides, fertilizers, or antibiotics. Additionally, we supply grass-fed certified product for brands targeting the premium natural nutrition segment. Certification documentation accompanies every shipment.

Q: How should I store this ingredient for maximum shelf life?

A: Store in the original sealed packaging at 10–25°C with relative humidity below 65%. Keep away from direct sunlight, heat sources, and strong odors. Under these conditions, our premium Whey Protein maintains full nutritional integrity and specification compliance for 18 months from manufacture. After opening, reseal tightly and use within the recommended timeframe.
