Beadlets Lutein Zeaxanthin Lycopene Microencapsulation — field notes from the carotenoid aisle If you’ve followed carotenoids the past few years, you’ve seen the shift: formulators want clean-label, vegetarian beadlets that disperse in cold water yet stand up to tableting pressure. To be honest, it was overdue. The uptick in ophthalmic and healthy-aging SKUs made it inevitable. This is where Beadlets Lutein Zeaxanthin Lycopene Microencapsulation gets interesting—free-flowing, gelatin-free spheres that behave nicely in the real world, not just in PowerPoint. What’s trending and why it matters Three trends collide here: cold-water dispersibility for better bioavailability, microencapsulation for oxidative stability, and vegetarian systems that ditch gelatin. In fact, many customers say they switched because “powders stopped clumping and tabs stopped chipping.” It sounds small. It isn’t. Technical snapshot Beadlets Lutein Zeaxanthin Lycopene Microencapsulation are spherical, free-flowing particles designed for capsules and tablets. The carrier system typically uses plant-based matrices with antioxidants, enabling good compressibility and sustained color integrity. Parameter Typical spec (≈) Method / Standard Lutein content 10–20% w/w HPLC, USP monograph/EP Zeaxanthin content 2–5% w/w HPLC, AOAC 2016.13 Lycopene content 5–10% w/w HPLC, USP/FCC Particle size 20–40 mesh, free-flowing USP Sieve Dispersibility T90 ≤ 30 s in 200 mL water (20°C) In-house, per AOAC guidance Heavy metals Pb ≤ 1 ppm; As ≤ 1 ppm; Cd ≤ 0.5 ppm; Hg ≤ 0.1 ppm ICP-MS, USP Shelf life 24 months, ≤25°C, ≤60% RH ICH Q1A(R2) Process flow (how it’s made) Materials: carotenoid oleoresins, plant-based carrier matrix, antioxidants, emulsifiers, purified water. Methods: pre-emulsification → high-shear homogenization → microencapsulation via spray-drying and fluid-bed layering → antioxidant fortification → classification → metal detection. Stability verified by accelerated testing (40°C/75% RH, 6 months; carotenoid retention typically ≥90%, real-world use may vary). Certifications: ISO 9001, FSSC 22000, Halal, Kosher (typical for this class; verify batch COA). Origin: Building 23B1, No.2 Yuanboyuan St., Zhengding Area of China (Hebei) Pilot Free Trade Zone.

Small digression: color targets can be tuned—handy for brand managers chasing a specific Pantone. Two quick case notes Tablet brand in the EU swapped in these beadlets; friability dropped from 1.0% to 0.3% and dissolution stayed clean. “No more orange dust on the line,” the ops lead joked. A beverage sachet maker reported zero clumping in pilot runs and kept the vegetarian claim intact.
