Abstract
This invention relates to the encapsulation of vitamin and mineral nutrients in a mixture of non-toxic solid cellulose derivative and a non-toxic solid hydroxylated lipid material by fluidizing the nutrient in a gaseous stream and contacting the nutrient with finely atomized droplets of coating solution whose solvent is operative to dissolve the ingredients of the mixture. The gas stream volatilizes and removes the solvent. The fluidization and solution contact are repeated through a number of sequential coatings which aggregate separately coated nutrient particles and encapsulate the aggregate with a continuous substantially odor inhibiting coating matrix.
