The present invention relates to a stable, tasteless fat soluble vitamin emulsion composition which can be sprayed on foodstuffs at room temperature, particularly ready-to-eat breakfast cereal, for the purpose of vitamin fortification of said foodstuffs.

Fat soluble vitamin emulsions suitable for spraying onto foodstuffs

The subject invention relates to a process for preparing acetaminophen powders by spray drying the acetaminophen in the presence of various excipients. Preferably a lubricant is incorporated into the acetaminophen powder during the spray drying process or after the spray drying process by passing the spray dried acetaminophen powder through a fluidized bed dryer which contains a lubricant.

Process for preparing spray dried acetaminophen powder and the powder

The subject invention relates to a process for preparing a powder containing a water-soluble vitamin which is directly compressible into a tablet prepared by spray drying (a) an aqueous slurry of a water-soluble vitamin and a binder; (b) preferably an adsorbent; and (c) a lubricant. Particularly useful water-soluble vitamins are ascorbic acid, sodium ascorbate, and calcium ascorbate. The unique feature of the process is that the lubricant is spray dried along with the other components. The invention also relates to powders prepared by this process. The powders are directly compressible into tablets and will not demix.

Vitamin-active powders which are more free-flowing and stable, than conventional fat-soluble vitamin powders are prepared utilizing special silicon-containing materials which are predominately in the form of substantially discrete agglomerates. The agglomerates are such that preferably 50 percent of the total have a minimum length, width, or both of 300 microns.

Free-flowing, high density, fat soluble vitamin powders with improved

The subject invention relates to a vitamin C powder prepared by (a) spray drying an aqueous slurry of ascorbic acid and binder in the presence of an absorbent in amounts such that the resulting powder will contain at least 90 percent by weight of ascorbic acid, no more than 9 percent by weight of binder, from 0.2 to 2 percent by weight of absorbent; and blending from 0.2 to 5 percent by weight of a lubricant into the powder prepared by step (a). Preferably microcrystalline cellulose and mixtures of microcrystalline cellulose and hydroxypropylmethycellulose are used as the binder. The resulting sugar and starch free vitamin C powder prepared by this process will be free flowing, have an ascorbic acid content of at least 90 percent by weight, be color stable under use conditions, will contain a lubricant, and is directly compressible into tablets which have acceptable hardness, friability, color stability, and disintegration times.

Process for preparing a sugar and starch free spray-dried vitamin C

Vitamin A palmitate compositions stable against crystallization at low temperatures are prepared by blending therewith a monoterpene such as dl-limonene. Vitamin A active concentrates prepared utilizing low temperature stabilized vitamin A palmitate are prepared by blending therewith an acceptable feed or food grade emulsifier.

Low temperature stable, emulsifiable vitamin A concentrates

Encapsulated vitamin powders coated with a hydrophobic silica have improved free-flowing properties making these powders more suitable for direct tableting preparation.

Spray-dried vitamin powders using hydrophobic silica

Spray dried vitamin E powders comprising 50 to 56 percent by weight vitamin E, 1 to 25 percent by weight hydrolyzed gelatin and 20 to 30 percent by weight caseinate. The resulting powders can be directly compressed into tablets of improved hardness and friability.
