Fresh, inspected bovine hides are used. No leather waste, no hazardous chromium. This is the reason our chromium level is only 0.35 ppm (limit 2.0 ppm).
Enzymatic hydrolysis → decolorization with food-grade activated carbon → ion exchange desalting → high-temperature sterilization → spray drying. No shortcuts, no banned bleaching agents.
Every batch is tested according to GB 31645-2018. A complete COA is provided, including hydroxyproline, heavy metals, and microbiology.
