Chinese Food-Grade Silica: Zhongqi Silicon Defines a New Safety Benchmark with 21 Patents

Technical highlights: 21 patents (including 3 invention patents), GMP-level dust-free workshops, adsorption capacity 1.5 times higher than the national standard

As one of China’s first enterprises to obtain the Food Additive Production License, Zhongqi Guangdong Silicon Industry relies on two production bases in Guangzhou and Fujian (annual capacity of 30,000 tons). Its innovatively developed food-grade silica has passed ISO22000 and Halal certifications, with lead content ≤ 1mg/kg (national standard: 5mg/kg). In milk powder and coffee powder, its original particle size control technology (D50=12-15μm) reduces caking rate by 78%, and its market share has ranked first in South China for 10 consecutive years.
