Raw material preparation: Select appropriate raw materials such as animal bones, skin, etc., and conduct acceptance and pre-treatment.

Acid hydrolysis: After cutting the raw materials into small pieces, add an acidic solution and perform an acid hydrolysis reaction under high pressure and high temperature to decompose collagen into amino acids.

Soaking and cleaning: After acid hydrolysis, the raw materials need to be added to a large amount of water, repeatedly soaked and stirred to remove impurities and acidic substances.

Decolorization: Use decolorizing agents to remove pigments and other impurities from raw materials, improving the purity of gelatin.

Filtration: Filter out residual solid impurities through a filter screen to obtain pure colloidal liquid.

Concentrate: Heat the colloidal solution to evaporate water, so that the collagen solution reaches a certain concentration.

Gel: cool the concentrated collagen solution to a specific temperature to form a gelatinous gel. This process can be adjusted by adding edible acids, sweeteners, etc. to regulate the taste.

Slicing and drying: cut the gel into even small pieces or strips, and then dry it naturally or with hot air in a ventilated drying room to obtain dried gelatin products.

Throughout the entire production process, it is necessary to strictly control parameters such as temperature and pH value to ensure the quality and safety of the product. At the same time, treat the wastewater and waste generated to meet environmental protection requirements.
