Production Process

Gelatin production typically involves acid, alkaline, or enzymatic partial hydrolysis of collagen in animal hides, followed by heating extraction, filtration, concentration, high-temperature sterilization, drying, and pulverizing. The process converts naturally insoluble collagen into water-soluble colloids.

Strict quality control over incoming raw materials; fresh animal hides are carefully selected from qualified suppliers.

Raw materials are washed, then partially hydrolyzed using alkaline or acid methods to break and separate the triple-helix collagen structure, preparing for heating extraction.

Raw materials are heated at 55–65°C and soaked for 6–8 hours to release gelatin. Hot water is added multiple times with rising temperatures, ending with a slight boil to fully dissolve collagen into gelatin.

The gelatin solution is filtered using filter aids such as filter cotton, activated carbon, or diatomaceous earth on a plate and frame filter press to remove solid impurities, yielding a clarified gelatin solution.

The clarified gelatin is concentrated from an initial 4–7% to 25–30% solids using ultrafiltration membranes and flash evaporation.

The concentrated gelatin passes through a U-tube sterilizer at 140°C for 6 seconds, then rapidly cooled to 55–60°C, effectively eliminating E. coli and Salmonella.

After sterilization, gelatin is cooled, extruded into strips, dried over 8 chambers for about 3 hours to 9–11% moisture, then pulverized into semi-finished products.

Semi-finished products with different specifications are blended according to customer requirements to produce final products meeting their standards.

The quality control department tests the blended finished products according to internal standards exceeding national regulations, ensuring compliance with the highest domestic and international quality requirements.

Finished products are delivered safely and on time in accordance with customer requirements.
