OmniMixer®Vitamins premix Applications:

Vitamins act as "catalysts" in human metabolism. Vitamins B complex (B1, B2, B6, B12, etc.), which are found in OmniMixer®Vitamins premix, participate in energy metabolism. They help convert food into energy and alleviate symptoms such as fatigue and weakness. Vitamin C promotes collagen synthesis to maintain the health of skin, blood vessels, and bones. Vitamin D regulates calcium and phosphorus absorption to prevent osteoporosis and rickets.

■ Supplier onboarding and dynamic management

Richtek conducts unscheduled audits of suppliers and has established a comprehensive quality control system for supplier audits. This system includes quality monitoring of the raw material production process, such as vitamin synthesis process parameters and stabilization treatment technology, as well as factory inspection procedures. These measures ensure that suppliers can consistently provide qualified raw materials. Additionally, new suppliers' raw materials undergo small-scale trials focusing on activity stability, compatibility with other ingredients, and performance in actual applications, such as synergistic effects with other components in premixes. Richtek regularly evaluates its supplier partners (e.g., annually), grading them based on metrics such as batch pass rate, quality variability, and post-sales response speed. Suppliers with recurring quality issues are suspended or terminated to ensure consistent raw material quality.

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

☑  OmniMixer®Vitamin B complex premix

OmniMixer®Vitamins premix is used in food to fortify its nutritional value, compensate for deficiencies in naturally occurring vitamins, and meet the nutritional needs of different populations. Common applications include infant formula, functional foods developed for specific populations (e.g., office workers and the elderly), and fortified foods to which premixes are added to enhance the nutritional value of ordinary foods. The health food and dietary supplement sector includes composite vitamin formulations and specialty supplements. Additionally, vitamin premixes are used in formula foods intended for individuals with diseases or special physiological conditions to prevent deficiencies caused by absorption disorders.

In feed field, OmniMixer®Vitamins premix primarily provides nutrition for farmed animals to ensure their growth, reproduction, and product quality. OmniMixer®Vitamins premix is typically added to livestock and poultry feed, as well as to aquatic feed.

Customized formulation capabilities for OmniMixer®Vitamins premix:

The formulation of OmniMixer®Vitamins premix is customised based on human nutritional needs, food safety regulations, and food processing characteristics, while also taking into account bioavailability, stability, and sensory compatibility. The formulation emphasizes precise compliance, human compatibility, and process tolerance.

The combined action of several vitamins can strengthen the immune system. Vitamins C and E and beta-carotene, a precursor to vitamin A, are powerful antioxidants that neutralize free radicals and protect immune cells from damage. Vitamin B6 is involved in antibody synthesis, and vitamin D regulates immune cell activity and reduces the risk of infection. Individuals with weakened immune systems, such as the elderly or those recovering from surgery, can benefit from OmniMixer®Vitamins premix to help restore their body's defensive capabilities more quickly.

▶ Immune health

■ Target population and application scenario customized technology

Different populations have significant differences in their vitamin requirements based on age, physiological condition, and health needs, which serve as the core basis for formula customization. The types of vitamins in vitamin premixes, the target fortification levels of vitamins in formulations, and reasonable formulation designs and product customizations are determined based on different population groups, such as infants (0-3 years old), pregnant women/lactating mothers, the elderly, and athletes, as well as different application scenarios in products, such as infant formula, prenatal nutritional supplements, elderly nutritional supplements, and sports drinks.

Stabilisation technology for OmniMixer®Vitamins premix:

Vitamins (especially fat-soluble vitamins A, D, and E, and water-soluble vitamins B1 and C) are easily degraded by factors such as light, heat, oxygen, humidity, and pH, and therefore require stabilisation technology for protection.

■ Microencapsulation technology

Microencapsulation is used to protect vitamins prone to oxidation (such as vitamins A, E, and C) by forming a protective layer using food-grade materials (such as gelatin, arabic gum, modified starch, and chitosan) through emulsification-spray drying or coagulation methods, thereby isolating oxygen and moisture. For light-sensitive vitamins (such as vitamins B2 and B12), light-blocking wall materials are used, or multi-layer coating (core layer - intermediate layer - outer layer) is employed to enhance protection.

■ Antioxidant synergy technology

Adding food-grade antioxidants, such as vitamin E, ascorbyl palmitate, and rosemary extract, to premixes creates synergistic protection with vitamins that are prone to oxidation. For example, combining vitamin A with vitamin E reduces oxidative loss.

Vitamins C, E, and A have antioxidant effects that reduce damage to cells caused by free radicals, delaying skin aging (e.g., wrinkles and spots) and reducing the risk of chronic diseases, such as cardiovascular disease and diabetes. Studies have shown that long-term, moderate supplementation with OmniMixer®Vitamins premix improves vascular endothelial function, reduces lipid oxidation deposits, and protects cardiovascular health.

▶ Antioxidant

■ Raw material receiving inspection

The purity and safety of vitamin raw materials are of the utmost importance, and impurities, microorganisms, and contaminants must be removed through pretreatment.

Raw material screening and purity testing technology: High-performance liquid chromatography (HPLC), gas chromatography (GC), or near-infrared spectroscopy (NIRS) are used to test the purity of vitamin raw materials (e.g., vitamin C purity must be ≥99%), while also testing for heavy metals, microorganisms, and other indicators.

Carrier pre-treatment technology: Carriers (such as maltodextrin) must undergo drying (moisture content ≤5%), grinding (particle size controlled at 80-120 mesh), and sterilisation (such as UV or microwave sterilisation) to improve their flowability and adsorption capacity for vitamins, and to prevent vitamin degradation caused by impurities or moisture introduced by the carrier.

■ Customized formulation technology

Richtek has formulation customization technology that meets its customers' diverse product needs. Richtek uses databases such as the China Nutrient Manufacturing Network, the National Nutrition and Health Data Center, and the Core Ingredients System, Richtek provides precise, exclusive, one-to-one formulation customization services through the use of high-throughput computing and intelligent synthesis science.

The formulations adhere to the basic principle of using the "daily intake" of the target population as the benchmark and combining it with the "daily consumption" of food to calculate the additional amount. This amount is adjusted according to the process loss rate. Additionally, the synergistic and antagonistic effects of vitamins must be considered.

High-precision mixing technology for OmniMixer®Vitamins premix:

The vitamin content in OmniMixer®Vitamins premix is typically present in trace amounts (e.g., only 0.1–1 mg of vitamin B12 per kilogram), necessitating the use of mixing technology to ensure uniform distribution of all components (coefficient of variation CV ≤ 5%).

■ Graded dilution and mixing technology

This stepwise process employs a ‘small-dose raw material → sequential dilution → final mixing’ approach to prevent uneven distribution of trace vitamins caused by direct mixing with large amounts of carrier material. For example, first mix 1g of vitamin B12 with 100g of carrier (1:100 dilution), then mix the mixture with 10kg of carrier (1:100 secondary dilution), ultimately achieving uniform dispersion.

■ Storage condition control

The raw materials for vitamins (especially fat-soluble vitamins, vitamin C, etc.) are sensitive to light, heat, oxygen, and humidity. Improper storage can result in a loss of activity. Therefore, storage environments must be specifically controlled.

Richtek minimizes activity loss in vitamin raw materials by controlling environmental parameters such as temperature, humidity, light, and oxygen. Additionally, strict adherence to storage management guidelines ensures that raw materials are used on a “first-in, first-out” basis. Storage and expiration dates are clearly marked to prevent expired materials from entering production. Different types of vitaminc raw materials are stored separately to prevent cross-contamination or accelerated degradation. Storage conditions are regularly inspected for caking, leakage, or odors, and any suspected deteriorated materials are immediately isolated and retested.

■ pH buffering technology

For pH-sensitive vitamins, such as vitamin B1, which decomposes under alkaline conditions and vitamin C, which is more stable under acidic conditions, buffering agents, such as sodium citrate and sodium dihydrogen phosphate, are added to regulate the pH of the system (typically maintained between 4.0 and 6.0) and ensure stability.

■ Granulation and forming technology

Some OmniMixer® vitamins premixes require granulation for solid beverages or tablet candies, which requires balancing particle size uniformity with vitamin stability. Spray drying granulation technology rapidly dries the mixture into granules in hot air. This process is suitable for water-soluble vitamins because it reduces exposure time to high temperatures and minimizes degradation. Low-temperature extrusion granulation technology extrudes the mixture into granules at temperatures as low as 60–80°C. This process is suitable for heat-sensitive vitamins, such as vitamins A and D, and it allows for adjustment of granule hardness and density. Micro-pellet coating technology applies a secondary coating (e.g., hydroxypropyl methylcellulose or beeswax) to the granules to further isolate moisture and oxygen, thereby extending shelf life.

■ Specialised mixing equipment technology

OmniMixer®Vitamins premix can be processed using low-shear mixers (such as twin-screw conical mixers or three-dimensional motion mixers) to avoid high shear forces that can damage vitamin structures (e.g., vitamin C is prone to oxidation under shear friction-induced heat), ensuring uniformity. Vacuum mixing technology mixes in a vacuum environment, reducing oxygen exposure and lowering the risk of oxidation for fat-soluble vitamins (such as vitamins A and E). Richtek's mixing equipment features rapid cleaning functionality (such as CIP in-place cleaning systems) to prevent cross-contamination from residual materials between different batches or formulations (especially for allergenic vitamins like vitamin B12 and their separation from other components).
