Abstract
Abstract A pharmaceutical, confectionery or food tablet coated on all its exterior surfaces with maltodextrin, which masks the characteristic taste of the tablet ingredients and does not have a slimy taste, with the coating composition comprising maltodextrin, an effective amount of a plasticizer to make the maltodextrin non-brittle and non-cracking when coated onto a tablet, an effective amount of a detackifier for making the maltodextrin and plasticizer non-tacky, a secondary film former to impart gloss and strength to the maltodextrin film coating, and a colorant for imparting color. A method of making tablets coated with maltodextrin.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
68 words
A film modifier for adding to a primary film-former consisting essentially of powdered particles of film-forming non-toxic edible maltodextrin to make an edible film coating composition, the film modifier comprising a dry mixture obtained by dry blending a plasticizer suitable for making the maltodextrin non-brittle and non-cracking when coated onto a tablet, and an effective amount of a detackifier suitable for making such plasticized maltodextrin non-sticky or non-tacky.
Claim 2
Dependent Claim
68 words
A film modifier for adding to a primary film-former consisting essentially of powdered particles of film-forming non-toxic edible maltodextrin to make an edible film coating composition, the film modifier comprising a dry mixture obtained by dry blending a plasticizer suitable for making the maltodextrin non-brittle and non-cracking when coated onto a tablet, and an effective amount of a detackifier suitable for making such plasticized maltodextrin non-sticky or non-tacky.
Claim 3
Dependent Claim
24 words
The film modifier of claim 1, including an effective amount of secondary film former to impart gloss and strength to the maltodextrin film coating.
Claim 4
Dependent Claim
17 words
The film modifier of claim 1, including a colorant for imparting color to the maltodextrin film coating.
Claim 5
Dependent Claim
16 words
The film modifier of claim 3, said colorant being titanium dioxide, FD&C lakes, or D&C lakes.
Claim 6
Dependent Claim
15 words
