OmniMixer®Proteins premix Applications:

OmniMixer®Proteins premix is often combined with whey protein (rapid absorption, increasing blood amino acid levels within 30 minutes) and casein (slow-release absorption, providing sustained energy for 6–8 hours). This combination meets the immediate protein needs after exercise or surgery while maintaining a prolonged supply of amino acids, thereby preventing muscle breakdown. Single-source proteins may have amino acid deficiencies (e.g., soy protein lacks sufficient methionine). Premixes combine animal and plant proteins to achieve amino acid complementarity, enhancing protein utilisation (the protein digestibility-corrected amino acid score PDCAAS approaches 1.0).

■ Supplier onboarding and dynamic management

When it comes to regulation, access is the first line of defense. Richtek screens suppliers against strict standards to avoid "source risk." Richtek requires suppliers to provide complete qualification documents to confirm their legal production and quality assurance capabilities. Richtek also conducts random audits of suppliers' production capabilities and quality systems, and requires them to provide a complete traceability chain for raw materials.

OmniMixer®Proteins premix is available in the following specification and contents, customized according to requirements:

☑  OmniMixer®Proteins powder premix

OmniMixer®Proteins premix is commonly used in the production of dairy products, such as milk, yogurt, and milkshakes. Adding whey protein and casein premixes enhances the protein content, improves the texture, and increases stability. Protein powder for fitness enthusiasts and athletes is essentially a direct application of premixes, typically centered around whey protein and combined with branched-chain amino acids (BCAAs), creatine, glutamine, and other components. These premixes rapidly replenish post-workout protein needs and promote muscle repair and synthesis. Infant formula-grade protein powder premixes are a core ingredient in infant formula and rice cereal. They are based on whey protein and casein and combined with components such as DHA, ARA, and nucleotides. These premixes strictly adhere to infant nutrition standards, ensuring suitable amino acid composition and digestibility for infant development needs while reducing the risk of allergies (e.g., some use deeply hydrolyzed protein premixes).

In the feed field, OmniMixer®Proteins premix is used in the production of feed for livestock such as pigs, chickens, and cattle. The protein ratio and amino acid composition are adjusted according to different growth stages to promote animal growth and improve feed conversion efficiency. In aquaculture for fish and shrimp, OmniMixer®Proteins premix is combined with minerals and vitamins to meet the high protein requirements of aquatic animals, thereby promoting growth rates and survival rates.

■ Raw material receiving inspection

Richtek implements strict acceptance inspections for each batch of raw materials supplied by vendors and ensures their continued compliance through routine monitoring. Clear acceptance standards for raw materials are established based on product standards and regulatory requirements. Each batch of raw materials is inspected upon arrival for sensory, physical, and chemical indicators; safety indicators; contaminants; and heavy metals. In addition to incoming inspections, Richtek conducts unannounced audits of suppliers on a regular basis to verify consistency between production records and actual operations.

We also verify the status of raw material inventory and employee operational compliance. Furthermore, we require suppliers to provide a Certificate of Analysis (COA) for each batch of raw materials. We then compare the COA with the results of the incoming inspection. Any deviations must be within the permissible range (e.g., protein content deviation of no more than 1%).

Customized formulation capabilities for OmniMixer®Proteins premix:

The formulation design of OmniMixer®Proteins premix is a cross-disciplinary field that integrates nutrition science, materials science, and process engineering. It is a core component that determines the functionality, safety, and market adaptability of the product. To achieve the objectives of ‘nutritionally balanced, process-feasible, stable and controllable, and functionally compliant,’ a variety of technical approaches must be employed.

■ Antioxidant synergy technology

For products containing lipid components (such as milk fat in whey protein or added algae oil), this technology combines primary antioxidants with synergists to inhibit oxidation and extend product shelf life.

OmniMixer®Proteins premix contains dietary fiber, such as inulin and oligofructose, as well as probiotics, which regulate intestinal flora and relieve constipation caused by a high-protein diet. The digestive enzymes (such as protease) help break down proteins, making the product suitable for people with weak digestive systems, such as postoperative patients. Some premixes contain antioxidants, such as glutathione and vitamin E, which reduce free radical damage from protein metabolism. Plant protein premixes, such as soy protein, contain soy isoflavones, which have mild anti-inflammatory and endocrine-regulating effects.

■ Nutritional ratio optimisation technology

The core of formula design lies in the scientific calculation and formulation that ensures the composition of proteins and other nutrients aligns with the product's functional positioning while balancing efficacy.

Amino acid balance technology: This technology addresses the deficiencies in the amino acid composition of different protein raw materials. For example, plant proteins generally lack lysine, and whey protein has insufficient methionine. The technology optimizes the amino acid score (AAS) through "complementary ratios." It precisely supplements limiting amino acids, such as lysine in cereal proteins, and enhances the biological value (BV) of proteins by adding individual amino acids.

Nutrient synergy/antagonistic regulation technology: This technology utilizes synergistic interactions between nutrients to enhance efficacy.

For example, vitamin C promotes iron absorption, and calcium and vitamin D promote bone absorption synergistically. However, divalent metal ions, such as iron and zinc, can form precipitates with tea polyphenols and phytic acid, which reduces absorption rates. Therefore, the addition sequence must be controlled to avoid direct contact.

■ pH buffering technology

Adjusting the pH value of the formulation to maintain protein stability. For example, whey protein tends to precipitate at around pH 4.5 (isoelectric point). Buffering agents such as sodium citrate or sodium dihydrogen phosphate can be added to control the pH between 6.5 and 7.0, improving solubility and thermal stability (suitable for products requiring high-temperature sterilisation).

■ Protein hydrolysis modification technology

Enzymatic hydrolysis breaks down large proteins, such as whey and soy, into smaller peptides or free amino acids. This improves digestibility and absorption rates, making it particularly suitable for populations with weaker digestive functions, such as infants and the elderly. The degree of hydrolysis (DH) must be controlled to avoid excessive hydrolysis, which can result in a bitter taste.

■ Powder micronization technology

Through ultra-fine grinding (e.g., grinding to 100-200 mesh) or grading and screening, the particle size difference between different raw materials is kept to ≤20 mesh (e.g., protein powder and dietary fibre particle sizes are both controlled at 80-100 mesh), thereby reducing layering caused by density differences after mixing (e.g., lighter powders floating to the top and heavier powders sinking to the bottom).

■ Granulation technology

For multi-component premixes prone to layering, granulation processes (such as wet granulation or dry granulation) are used to compress the mixed powder into particles of 30–60 mesh. This ‘granulation’ fixes the component ratios, preventing layering due to vibration during transportation. For example, fitness protein powder premixes use granulation to solidify components such as whey protein, creatine, and vitamins into particles, ensuring uniform nutrition per scoop.

High-precision mixing technology for OmniMixer®Proteins premix:

The mixing stage is a critical step in ensuring the uniformity, stability, and functionality of protein powder premixes. Richtek has multiple technologies that address mixing challenges caused by differences in the characteristics of raw materials (e.g., density, particle size, and flowability).

■ Mixing equipment selection technology

Richtek selects suitable equipment based on raw material characteristics and production scale, which directly affects mixing efficiency and uniformity. Screw ribbon mixers are suitable for small to medium batches of raw materials with moderate flowability. Twin-screw mixers are used for large-scale continuous production, achieving forced mixing of raw materials in a sealed space through the pushing, kneading, and shearing actions of the screws. They are particularly suitable for premixes containing trace components, reducing cross-contamination. Three-dimensional mixers are designed for raw materials with significant particle size differences (such as protein powder and calcium carbonate), using multi-directional rotation of the mixing drum to create tumbling and diffusion mixing, thereby reducing the risk of layer separation.

■ Trace component dispersion technology

For components accounting for less than 1% of the premix, we use a stepwise mixing process to ensure uniform distribution. For OmniMixer®Proteins premix, we use a stepwise dilution method. First, the trace components are pre-mixed with carriers, such as lactose or maltodextrin, in a specific ratio. Then, the premix is blended with the bulk raw materials to prevent the trace components from clumping. We select carriers that are compatible with the trace components. For example, we use colloid-coated calcium carbonate to enhance the affinity of the premix with protein powder. Alternatively, we granulate the carrier to match the particle size with the protein powder (e.g., 80–100 mesh) to enhance adsorption.

■ Storage condition control

Improper storage of raw materials can result in spoilage, such as moisture absorption, oxidation, or insect infestation. Therefore, storage conditions for OmniMixer® Proteins premix must be strictly controlled. Different types of raw materials, such as whey protein, soy protein, vitamin premixes, and minerals, should be stored separately to prevent cross-contamination. Non-conforming raw materials should be isolated and labeled separately to prevent misuse. Since protein raw materials are prone to moisture absorption, warehouses must be kept dry and well-ventilated with controlled temperatures between 15 and 25 °C. Raw materials should be packaged in sealed containers, such as aluminum foil bags or vacuum-sealed bags. Once opened, containers must be resealed promptly and labeled with the opening date. Raw materials that are not fully used within a short period can be refrigerated (e.g., whey protein) to extend their stability.

■ Target population and application scenario customized technology

The formulation design should focus on the product's core functions (e.g., fitness and muscle building, nutritional supplementation, or use by specific populations) to ensure the nutritional components are rational and effective.

Richtek determines the proportions of the core nutritional components, selects the raw materials based on the product's positioning (e.g., whey protein for rapid absorption is suitable for fitness enthusiasts, while soy protein is a plant-based source suitable for vegetarians), and establishes the mixing ratios. Additionally, the amino acid score (AAS) of the proteins must be calculated to ensure an optimal balance of essential amino acids. Carbohydrates, fats, dietary fiber, and other components are added as needed to achieve nutritional complementarity. Functional ingredients are added to address specific needs.

Stabilisation technology for OmniMixer®Proteins premix:

Richtek can improve the functional properties (such as solubility and absorption rate) or stability of raw materials through physical, chemical, or biological processing.Preventive formulations are designed to prevent degradation caused by interactions between components or environmental factors during storage and use (such as caking, oxidation, or nutrient loss).

Infant formula-grade OmniMixer®Proteins premix strictly adhere to infant nutrition standards. Proteins are hydrolyzed into small peptide molecules, such as whey protein hydrolysate, to reduce the risk of allergies. Added fatty acids, such as DHA and ARA, work synergistically with proteins to promote neurological development. Products for athletes and fitness enthusiasts contain a high proportion of whey protein combined with creatine and branched-chain amino acids (BCAAs) to promote muscle synthesis and reduce post-exercise fatigue. The convenience of premixes meets the need for frequent protein supplementation.
