Formulation Review
配方考量
Review formulation factors that can affect ingredient handling, processing and finished-product development.
Dry-Blending Review
The documented particle-size requirement provides a useful starting point when evaluating dispersion and blend uniformity in dry formulations.
光線防護
Riboflavin is light-sensitive, so formulation development, processing and packaging should consider exposure to light.
Water Solubility & Dispersion
Riboflavin has relatively low water solubility compared with many other water-soluble vitamins. For beverage, liquid or high-uniformity systems, formulators should evaluate dispersion, dissolution conditions and the effect of the complete formulation rather than assuming rapid dissolution from the Vitamin B2 classification alone.
Finished-Product Fit
Evaluate dosage, excipients, processing conditions and the target dosage form before approving the ingredient for a specific formulation.
應用
Typical Formulation Uses
