Composition for soluble films with a new hydrolyzed polysaccharide

Abstract

The invention is concerned with film-forming compositions containing hydrolysates of the exopolysaccharide YAS34 for the use in pharmaceutical, veterinary, food, cosmetic or other products like films for wrapping foods, aspices or jellies, preferably for predosed formulations like soft or hard capsules.

1 . Film-forming composition containing hydrolyzed exopolysaccharide YAS34.  
     
     
         2 . Film-forming composition according to  claim 1 , wherein the BPS YAS34 is hydrolyzed to an average molecular weight range from 500,000 to 10,000.  
     
     
         3 . Film composition according to  claim 2 , wherein the hydrolyzed YAS34 has an average molecular weight of 45,000.  
     
     
         4 . Film composition, according to  claims 1  to  3  containing an additional setting agent for processing purpose.  
     
     
         5 . Film composition according to  claim 4 , wherein the setting agent is selected from carrageenan, gellan gum, pectin, agorose, gelatin, xanthan with locust bean gum, xanthan with konjac, or native EPS YAS34.  
     
     
         6 . Film composition according to claims  4  or  5 , wherein the setting agent is contained in an amount of 0.5 to 15% by weight.  
     
     
         7 . Film composition according to  claims 4  to  6 , wherein the setting agent is combined with salts of mono or divalent cations.  
     
     
         8 . Film composition according to  claim 7 , wherein the cation salt is contained in an amount of 0.01 to 5% by weight of the whole composition.  
     
     
         9 . Film composition according to  claims 1  to  8  containing additionally coloring agents, flavoring agents and/or plasticizers.  
     
     
         10 . Container produced from the film-forming composition according to  claims 1  to  9  for unit dosage forms of agrochemicals, seeds, herbs, foodstuffs, pharmaceuticals or flavoring agents.  
     
     
         11 . An aqueous solution of the film-forming composition according to  claims 1  to  9  for the manufacturing of soft and hard capsules.  
     
     
         12 . The aqueous solution according to  claim 11  containing hydrolyzed EPS YAS34 in an amount of 10 to 50%, preferably 15 to 40% by weight of the aqueous solution.  
     
     
         13 . The aqueous solution according to claims  11  and  12  containing an additional setting agent in an amount of 0.01 to 5%, preferably 0.03 to 3% by weight of the aqueous solution.  
     
     
         14 . The aqueous solution according to  claims 11  to  13  containing additionally salts of mono or divalent cations in an amount of 0.01 to 3%, preferably 0.01 to 1% by weight of the aqueous solution.  
     
     
         15 . Use of the aqueous solution according to claims  11  and  14  for the manufacturing of hard capsules in a dip moulding process.
