The production process for our gelatin includes: Pretreatment, washing, extraction, purification, drying, grinding, blending and packaging. Different quality control measurements are performed during the production process right through to the final release of the blend in order to guarantee the consistency of the product.
There are two different methods of pretreatment: The acid process (A-type) and the alkaline process (B-type).
The acid process (A-type gelatin): In this process, the bones or skins are treated in a vessel containing a dilute solution of acid for a predetermined period of time. Following this, the acid is washed out with cold water and pretreated raw materials are pH adjusted for extraction.
The alkaline process (B-type gelatin): Traditionally, in this process the demineralized bones are placed in liming pits and soaked in a periodically refreshed lime suspension during 60 days. Meanwhile, for the skins, a caustic soda solution is used over a shorter period of time. At the end of this treatment, the raw material is washed thoroughly in order to remove the excess of the alkaline solution and the pH is adjusted for extraction.
Extracting, purifying and drying gelatin
The same extraction method is used for both A-type and B-type processes. The extraction is carried out using water at controlled temperatures. The dilute gelatin solution from the extraction process is filtered, demineralized and concentrated in multiple-effect vacuum evaporators. The concentrated solution is sterilized, chilled and extruded to form gelatin noodles. These gelatin noodles then pass through a drying tunnel where they are dried with purified air. The final dry extracted product is then ground and tested for bacteriological quality and physico-chemical characteristics such as gel strength, viscosity and other parameters.
Grinding, blending and packaging
Different extracted gelatin products are ground, blended and packed as a final lot in order to ensure that the gelatin meets the specifications of our customers. The final product is subject to Quality Control testing that covers several different parameters before being released for delivery to the customer.
