E-mail:Product Overview & Core Technical Identity
SUNWAY supplies premium cold-water soluble microencapsulated Vitamin A Acetate 500,000 IU/g (50CWS), fully compliant with GB 1903.31-2018, FCC and USP standards. This spray-dried beadlet powder adopts food-grade wall material with built-in DL-alpha-Tocopherol antioxidant, effectively isolating retinol acetate from light, heat and oxygen to minimize potency loss during production and long-term storage. It features excellent free-flow property, uniform particle distribution and instant cold-water dispersion, widely recognized as cost-effective universal vitamin A fortification raw material for food, dietary supplement and feed industries. Every batch completes full HPLC potency, heavy metal and microbial testing, with 12-month sealed sample retention for full quality traceability. Mixed consolidated shipment with Vitamin D3 powder, DL-alpha-Tocopherol powder and other microencapsulated vitamins is available to reduce customers' integrated procurement and logistics expenses.

Physiological Functions & Industry Application Logic
Supported by WHO global micronutrient deficiency intervention guidelines, microencapsulated Vitamin A Acetate 50CWS retains all core nutritional activities of retinol acetate, while solving the natural oil vitamin's water insolubility and oxidation instability drawbacks:
Ocular Health & Vision Protection Promote rhodopsin synthesis in retinal cells to prevent night blindness, xerophthalmia and dry eye syndrome; essential fortifier for infant milk powder, children nutrition powder to eliminate global childhood vitamin A deficiency.
Mucosa Barrier & Immunity Enhancement Maintain intact epithelial tissue of respiratory, digestive and reproductive tracts, boost immune cell activity to reduce infection risks for sub-health crowds, pregnant women and the elderly.
Skin & Tissue Development Regulation Control keratinocyte metabolism to improve rough, dry skin; support fetal bone and epithelial growth during gestation.
Processing Stability Advantage of Microcapsule Form The spray-dried wall material forms physical isolation barrier against light and oxygen, greatly reduce activity loss during high-temperature baking, beverage homogenization and long shelf storage. Its cold-water dispersibility enables direct addition to aqueous food systems without extra emulsifiers.
Livestock Breeding Nutrition Booster Optimize animal reproductive performance, egg quality and fur gloss, reduce juvenile mortality caused by vitamin A deficiency in poultry, swine and aquatic feed formulas.
Key Property Reminder: Raw retinol acetate is extremely photosensitive; microcapsule technology significantly improves stability, but unpacked long-term exposure to strong light and temperature over 60C will still trigger potency degradation.
