Vitamin B2 CAS 83‑88‑5 | Dual‑Function Vitamin Raw Material for Nutrition Fortification & Natural Yellow Colorant

Many overseas food manufacturers, nutraceutical and feed producers face dual‑cost pressure. They need to purchase separate nutrition fortifiers and artificial colorants, which increases formula costs. Some vitamins tend to discolor and degrade during long‑distance sea transportation, leading to non‑compliant color and nutrition indicators and material losses.

Vitamin B2 (Riboflavin, CAS 83‑88‑5) serves dual purposes for nutrition fortification and natural yellow coloring. Its stable powder property stands up to ocean shipping, helping buyers simplify formulas and cut auxiliary‑material procurement costs. It is a widely‑used essential raw material for global food, nutraceutical and feed industries.

Core Differentiated Advantages for Overseas Buyers

1. Dual‑function to simplify formulas and reduce auxiliary‑material costs

Ordinary raw materials only provide nutritional fortification and require extra colorants.
Vitamin B2 delivers vitamin B2 fortification plus natural yellow coloring. It features uniform and color‑fast shade. Applied in solid drinks, grain products, tablet sugar‑coating and capsule shells, it reduces auxiliary‑material categories and lowers your procurement and management expenses.

2. Core metabolic co‑enzyme with market‑ready end‑product selling points

As a key component of flavoprotein prosthetic groups, Vitamin B2 governs oxidation‑metabolism of carbohydrates, fats and proteins.
It helps prevent angular cheilitis, glossitis, skin inflammation and eye discomfort caused by Vitamin B2 deficiency. It also supports hair & nail health and iron absorption. Whether for human supplements or animal feed, it brings clear selling points for end‑market sales.

3. Compliant dosage for global formula requirements

Well‑established application dosages are available for salt, infant food, grain products, solid beverages and milk drinks. Food‑grade and feed‑grade specifications are in stock, suitable for production formulas in Southeast Asia, Europe, America and other regions for easy manufacturing implementation.

4. Stable powder performance suitable for long‑distance sea export

Yellow‑to‑orange fine powder with reliable physicochemical properties. It resists discoloration and degradation during ocean transportation and long‑term storage. Consistent batch performance makes it ideal for large‑volume foreign‑trade orders.

5. Multiple mainstream grades: Vitamin B2 DC grade, USP grade, food grade, feed grade

We supply free‑flowing Vitamin B2 DC powder and USP‑standard material. They fit tableting, beverage compounding and premix feed applications to satisfy diverse production‑process requirements.

Product Functions

Vitamin B2 is a water‑soluble vitamin that cannot be synthesized by humans or animals and must be obtained from external sources.
It participates in biological oxidation and hydrogen transfer to maintain normal metabolism. Deficiency will disturb biological oxidation and trigger lesions including angular cheilitis, cheilosis, glossitis, conjunctivitis and seborrheic dermatitis.
In pharmaceutical applications, it relieves disorders caused by Vitamin B2 deficiency. In biochemical research, it works as photocatalyst and reference reagent.

Main Overseas Application Scenarios

– Food Industry: Vitamin B2 fortification for grain products, bread, pastries, solid drinks, milk beverages, table salt and dairy goods; used as natural yellow colorant.
– Nutraceutical & Pharmaceutical: B‑complex vitamin supplements, pharmaceutical preparations, yellow colorant for tablet sugar‑coating and capsules.
– Animal Nutrition: Livestock, aquaculture and pet feed to avoid Vitamin B2 deficiency and guarantee healthy growth & metabolism.
– Research Field: Biochemical experiment and reference raw material.
