Gelatin is a mixture of peptides and proteins produced by partial hydrolysis of collagen extracted from the skin, bones, and connective tissues of animals such as domesticated cattle, chicken, pigs, and fish. It is rich in protein, and has a unique amino acid profile that gives it many potential health benefits. There is enormous evidence that gelatin reduce joint and bone pain, increase brain function and reduce the signs of skin aging.

* Clean the fish skins with cold water to remove substantially all the superfluous material and cutting into small size.

* Treat with dilute alkali solution.

* Wash with plenty of water in order to remove excess alkali.

* Neutralize by repeated washing.

* Treat the neutralized fish skins with citric acid.

* Wash the citric acid-treated fish skin solution with cold water until the solution is substantially neutral.

* Extract the neutralized citric acid-treated fish skin with hot water to solubilize partially degraded collagen materials.

* Remove impurities, the aqueous solubilized gelatin solution then filtered through a cellulose/diatomaceous earth plate or frame filter.

* De-ionize through using a cationic-anionic resin bed.

* Concentrate, dry, pulverize and pack it.
