Nupure's Calcium Caseinate
Caseinates are produced by the
neutralization of acid casein with alkali. All caseinates are substantially water-soluble and are
typically prepared as a solution of about 20% solids prior to spray drying.
The film-forming properties of
soluble casein products, such as
sodium and calcium caseinates.
This specific property of casein products was recognized many years ago when
casein was used in technical, non-food applications such as paper coating, and
in paints and leather finishing. Commercially, the film-forming ability of
caseinates in foods is seen at the oil-water interface in the formation
of emulsions in coffee whiteners,
desserts, and whipped toppings, and at
the air-water interface in whipping and foaming products (such as whipped
toppings). These same properties have been used in the production of sausage
skins. More recently, caseinates have been used to coat fruit and vegetable
products as a means of maintaining their freshness. As a hydrophilic
(water-loving) substance, casein produces films that, on their own, are not
very resistant to the passage of moisture vapor.
