About Whey Protein Concentrate

Whey Protein Concentrate (WPC) is a dairy-derived, high-quality, complete protein source manufactured via Ultrafiltration (UF), a non-denaturing, low-heat process that selectively concentrates the protein while allowing lactose and minerals to pass through, preferred by wpc manufacturers. WPC is defined by its protein ...

Safety Profile

Generally Recognized as Safe (GRAS) as a food ingredient/supplement

Major Allergen Warning

Contains Milk/Dairy. Mandatory labelling is required globally (FALCPA, EU Food Information to Consumers Regulation) for export

Key Risk

Lactose Content (for WPC34 grades, not WPI) can cause gastrointestinal discomfort in lactose-intolerant individuals

Handling

Fine dust may be irritating to eyes and the respiratory tract. Handlers Should use appropriate dust masks/respirators in bulk transfer environments. Ensure stock rotation (FIFO - First In, First Out) to use the oldest product first, minimising Maillard risk

Microbiological Control

STRICT Regulatory limits for total plate count, Coliforms, E. coli, Salmonella, and Staphylococcus aureus

Sports Nutrition

(Muscle Synthesis & Recovery): High Leucine content directly activates the mTORC1 signalling pathway, which is the master regulator for initiating muscle protein synthesis (MPS). Rapid digestion ensures fast delivery of EAAs to muscle tissue

Functional Foods

(Texture & Nutritional Enhancement) Excellent emulsification and gelation properties due to its globular protein structure. Improve texture in low-fat products, increase protein content in bars and baked goods, and stabilise beverages

Medical & Clinical Nutrition

(Sarcopenia & Injury Recovery)Fortified enteral feedings for patients, elderly care, recovery from trauma or surgery, where the highly bioavailable amino acids support nitrogen balance and tissue repair

Infant Formula

(Protein Source) Highly purified and heat-treated WPC fractions (often demineralised) are used to match the protein ratio (Whey:Casein) found in human milk

Temperature Control

Cool storage: Maximum temperature should be 25°C (77°F) or lower. Higher temperatures significantly accelerate the Maillard reaction and reduce Lysine bioavailability (a critical EAA)

Relative Humidity (RH)

(Dry Storage) Maximum RH should be 65% or lower. High humidity causes moisture uptake in the powder, increasing its water activity (Aw), leading to caking, clumping, and the risk of microbial spoilage

Light & Air

(Dark and Sealed) Store away from direct sunlight, which can induce fat oxidation and off-flavors (rancidity). Packaging must exclude ambient air/oxygen

Avoid Refrigeration/Freezing

NEVER store WPC in a refrigerator or freezer. Frequent temperature cycling causes condensation inside the package, introducing moisture that leads to rapid clumping and spoilage

Shelf Life Standard

Typically 12 to 24 months from the date of manufacture when stored at ≤ 25°C and ≤ 65% RH

Moisture Control

Packaging must contain a Food-Grade Desiccant Pack (Silica Gel or Clay-based) to scavenge residual moisture and maintain powder flow and texture over time
