Estimating the term…
A gelatin product which offers highly improved properties of wettability and dispersibility in aqueous liquids irrespective of temperature and which permits accelerated dissolution in the hot state irrespective of the concentration is constituted by 90 to 99.9% by weight of a basic gelatin of any desired origin having a Bloom strength within the range of 0 to 350 grams and a viscosity within the range of 1 to 100 mPa.s. The gelatin product is also constituted by 0.1% to 10% by weight of a hydrolyzed gelatin of any desired origin having a mean molecular weight of 500 to 30,000. The method of preparation includes coating the particles of a basic gelatin with a film of hydrolyzed gelatin. The resulting product is well suited for all the usual applications of gelatin.
A gelatin product having improved wettability and dispersibility properties, comprising particles of a basic gelatin coated with a film of a hydrolyzed gelatin.
A method of preparation of a gelatin product having improved wettability and dispersibility properties and comprising particles of a basic gelatin coated with a film of a hydrolyzed gelatin, comprising the steps of agitating a quantity of the basic gelatin particles, dissolving a quantity of the hydrolyzed gelatin at a concentration of 0.1 to 5% by weight in an aqueous liquid at a temperature within the range of 10.degree. to 80.degree. C., agitating and wetting the basic gelatin particles with the hydrolyzed gelatin solution by sprinkling, immersion or spray-atomization to coat the particles with a film of the hydrolyzed gelatin and so as to ensure that the proportion of added hydrolyzed gelatin is within the range of 0.1 to 10% by weight of dry extract with respect to the mass of basic gelatin expressed in weight of dry extract, and drying the film-coated gelatin particles.
