Production of GelatIn
Gelatin is produced from partial hydrolysis of animal collagen, which is found in animal skins and bones.
Main raw material used to produce gelatin are bovine skins and bones, pig skins and fish skins.
We offer only halal and kosher gelatin, that’s why our gelatin is produced from bovine skins and bones and fish skin.
There are two types of gelatin in terms of production that depends on the treatment of the raw materials, namely acid treated or alkali treated. Dilute sulfuric acid or
hydrochloric acid is used for acid treatment, lime or sodium hydroxide is used for alkali treatment.
Gelatin produced using acid treatment yields Type A gelatin, where gelatin produced using alkali treatment yields Type B gelatin.
Type A gelatins are mostly derived from pig skins. Pigs tend to be of younger age when they are slaughtered, requiring only a treatment with dilute acid instead of strong
alkali treatment. Pig skins tend to be fattier as well, in order to prevent saponification (soap formation) during treatment acid is preferred over alkali.
However, some manufacturers optimized the acid treatment process for bovine skin and can offer halal type A bovine gelatin as well.
Type B gelatin is preferred for bovine skins and bones, because when cattle are slaughtered their age tends to be older compared to pigs and require stronger alkali treatment instead of acid.
Gelatin from fish skins can be type A or B depending on the treatment method.
Main difference between Type A and Type B gelatin is the isoelectric point – the pH at which the net charge of gelatin is zero. Type A gelatin tends to have IEP around pH 9, where Type B gelatin tens to have IEP around pH 4. IEP affects the surface effect properties of gelatin, so depending on the pH of the matrix of the product, the users of gelatin can either choose Type A or Type B gelatin for more effectiveness of the desired functionality.
