Milk Protein Powder

Premium Dairy Ingredient Base by Xi'an Tihealth

Formulating high-protein, low-carbohydrate dairy products requires an ingredient that delivers clean flavor without contributing excess lactose or minerals. Xi'an Tihealth provides pharmaceutical and food-grade Milk Protein Concentrate (MPC) engineered specifically for advanced food processing and sports nutrition.

Derived from premium skim milk via a gentle, low-temperature ultrafiltration and diafiltration process, our MPC retains the natural 80:20 ratio of Micellar Casein to Whey Protein in its native, undenatured state. Available in high-protein specifications (up to 85%), our proprietary enzymatic and membrane-filtration protocol reduces lactose to trace levels (<0.5%). With exceptional solubility, superior emulsification, and a neutral dairy profile, it is the foundational ingredient for RTD protein shakes, clinical nutrition formulas, protein bars, and processed cheese applications.

Standard milk powders often cause formulation issues due to their high lactose content (which leads to browning/Maillard reaction during heating) and poor solubility. Our MPC eliminates these B2B hurdles:

•  
• Ultra-Low Lactose (<0.5%):
• Standard skim milk powder contains nearly 50% lactose. Through advanced membrane diafiltration, we selectively strip out lactose and non-protein nitrogen. This prevents unwanted browning during UHT sterilization and makes the powder perfectly suited for Keto-friendly and lactose-intolerant formulations.
•  
• Undenatured Bioactivity:
• Because we utilize cold-process membrane filtration rather than harsh acid or heat precipitation, vital bio-fractions such as Immunoglobulins (IgG) and Lactoferrin remain structurally intact, retaining their potent immune-supporting properties.
•  
• Instantized Solubility:
• Subjected to advanced atomization during spray drying, the protein matrix forms micron-sized, agglomerated particles. This physical modification maximizes surface area, allowing the powder to disperse rapidly (within 30 seconds) in cold aqueous solutions without lumping.

Batch-to-batch consistency is critical for rheological stability in dairy processing. Below is the standard analytical data sheet for our high-spec MPC85.

Replacing non-compliant medical claims with scientifically validated nutritional profiles, our milk protein supports premium dietary formulas targeting:

Sustained Amino Acid Delivery (Anabolism)

The native 80:20 ratio of Micellar Casein to Whey provides a dual-action absorption profile. The rapidly digested whey triggers immediate muscle protein synthesis, while the casein forms a gel in the stomach, providing a slow, sustained release of amino acids for up to 7 hours, drastically reducing muscle catabolism.

Satiety & Metabolic Management

High-protein, trace-lactose dairy ingredients strongly stimulate the release of satiety hormones (such as GLP-1 and CCK). This delayed gastric emptying significantly increases feelings of fullness, making it a critical base for weight-management and meal-replacement shakes.

Cellular Immune System Support

Because our MPC is cold-processed, it retains essential bio-active whey fractions, including Immunoglobulins (IgG) and Lactoferrin. These glycoproteins play a vital role in supporting the body's natural defense mechanisms and promoting healthy iron metabolism.

• Processed Cheese & Dairy Manufacturing:
• Functions as a premier structural ingredient in processed cheeses and yogurts. Its superior emulsification and water-binding properties improve yield and prevent syneresis (weeping).
•  
• Sports Nutrition (Protein Powders & RTDs):
• The perfect foundation for premium protein shakes. Its low lactose content prevents gastric distress, while its neutral flavor profile minimizes the need for heavy masking agents in RTD beverages.
•  
• Clinical Nutrition (FSMP):
• Extensively used in enteral feeding formulas and postoperative recovery diets due to its complete amino acid profile, high digestibility (PDCAAS = 1.0), and low-allergen (lactose-reduced) nature.
•  
• Protein Bars & Extruded Snacks:
• Provides excellent dough pliability and reduces bar hardening over the product's shelf life compared to standard whey protein isolates.

Our extraction methodology guarantees the retention of native bio-structures while maximizing physical functionality in your mixing tanks:

1. Skim Milk Preparation:
2. Raw milk is centrifuged to completely remove butterfat, followed by brief, gentle pasteurization to ensure microbiological safety without denaturing the proteins.
3.  
4. Membrane Ultrafiltration (UF) & Diafiltration (DF):
5. The skim milk is pumped across specialized porous membranes. Water, lactose, and dissolved minerals pass through the membrane, while the large protein molecules (casein micelles and whey) are retained and concentrated. Diafiltration (adding water to wash out remaining lactose) is used to achieve concentrations of 80% to 85%.
6.  
7. Evaporative Concentration:
8. The liquid retentate is gently evaporated under a vacuum to increase solid matter before drying.
9.  
10. Spray Drying & Agglomeration:
11. The concentrate is atomized in a spray-drying tower. We utilize specialized agglomeration techniques to bind the fine dust into porous, micro-agglomerated particles, ensuring instant wettability and dispersion in cold water.

Dairy proteins are sensitive to moisture and ambient odors. Operating under an ISO9001:2015 Quality Management System, Xi'an Tihealth utilizes high-barrier packaging to ensure prolonged shelf life.

What is the difference between Milk Protein Concentrate (MPC) and Whey Protein Isolate (WPI)?

While WPI contains only the fast-digesting whey fraction of milk, MPC retains the native composition of milk: approximately 80% Micellar Casein and 20% Whey. This provides a thicker, creamier texture and a sustained-release amino acid profile, making MPC superior for meal replacements, protein bars, and nighttime recovery formulas.

Why is the ultra-low lactose content (<0.5%) important for my formulation?

Beyond catering to lactose-intolerant consumers, low lactose is a critical functional requirement for B2B processing. High lactose levels cause the Maillard reaction (browning) when exposed to heat during baking or UHT sterilization. Our <0.5% specification ensures your final product maintains a clean, white appearance and does not develop unwanted caramelized flavors.

How do you prevent the powder from clumping during liquid dispersion?

Standard milk proteins often form a hydrophobic shell when hitting water, leading to severe lumping (fish-eyes). We employ a specialized "Agglomeration" step during the spray-drying process. This creates porous, clustered powder particles that allow water to penetrate rapidly, resulting in instant dispersion (under 30 seconds) without the need for high-shear industrial blenders.
