Gathered tubular foodstuff wrapping based on cellulose

Abstract

The invention relates to a stick of a tubular food casing based on cellulose. The casing is produced by the NMMO process. The stick is particularly stable and is thus suited for automatic filling devices such as those used for producing cooked or boiled sausages.

1 . A stick of a tubular food casing based on cellulose characterized in that the casing is produced by the NMMO process.  
     
     
         2 . The stick as claimed in  claim 1 , characterized in that the casing has been transversely stretched by blow molding in the air section between annular die and surface of the spinning bath.  
     
     
         3 . The stick as claimed in  claim 1  or  2 , characterized in that the cellulose has a mean degree of polymerization DP of 300 to 700, preferably 400 to 650.  
     
     
         4 . The stick as claimed in one or more of  claims 1  to  3 , characterized in that the casing comprises up to 25% by weight, based on the weight of the cellulose, of further high-molecular-weight, slightly polar compounds.  
     
     
         5 . The stick as claimed in  claim 4 , characterized in that the further high-molecular-weight, slightly polar compound is a synthetic polymer or copolymer.  
     
     
         6 . The stick as claimed in one or more of  claims 1  to  5 , characterized in that the casing has a nominal caliber of 14 to 50 mm, preferably 16 to 25 mm.  
     
     
         7 . The casing as claimed in one or more of  claims 1  to  6 , characterized in that it comprises about 30 to 70 m, preferably about 40 to 60 m, of the casing.  
     
     
         8 . The stick as claimed in one or more of  claims 1  to  7 , characterized in that the casing comprises 8 to 20% by weight, preferably 16 to 18% by weight, of water.  
     
     
         9 . The stick as claimed in one or more of  claims 1  to  8 , characterized in that the casing comprises a plasticizer, preferably glycerol.  
     
     
         10 . The stick as claimed in one or more of  claims 1  to  9 , characterized in that the casing is provided with an impregnation or coating on the outside and/or on the inside.  
     
     
         11 . The stick as claimed in one or more of  claims 1  to  10 , characterized in that it is provided with an end closure.  
     
     
         12 . The stick as claimed in one or more of  claims 1  to  11 , characterized in that the ζ potential in the pH range from 6 to 10.5 is about −5 to −25 mV, and in the pH range from 3.5 to 5.5 is about +18 to −15 mV.  
     
     
         13 . The use of the stick as claimed in one or more of  claims 1  to  12  on a stuffing apparatus in the production of cooked-meat sausages or scalded-emulsion sausages, preferably in the production of small sausages.
