Hog Fat Ends

liver sausage

For many customers, the rustic look of the fat end is, beside the taste of the sausage, a quality characteristic for high value products. Fat ends have a strong texture and low permeability. Therefore, they are ideal for the manufacture of boiling sausage products such as liver sausage. Raw sausage filled into fat ends develop a special aroma due to a long maturing period.

Hog Bung Ends

Morcilla, Saucisse de Morteau, Andouillette

Because of their straight form and traditional look, hog bungs are popular casings for raw sausages. The renunciation of calibration gives the product an originality which is particularly appreciated in the Iberian Peninsula and Italy. Hog bungs ends are usually traded in bunches of 9m each.

DIF | Vasco Symbol


Ahle sausage, Feldkieker, Stracke

For the production of laminated hog casings (also: VASCO), the natural casing is cut open and applied flatly onto a form according to the required caliber. During a subsequent heating process, protein found inside the casings will emerge. Due to the coagulation effect, individual parts are combined to create a consistent and appealing surface. Classic products covered in VASCO-casing are, for example, the Hessian raw sausage specialities Ahlewurst or Feldkieker.

Sheep Casings

Wiener, Nürnberger, Frankfurter

Among natural casings, sheep casings have the narrowest caliber for particularly thin sausages. These casings combine tenderness with a strong texture and therefore allow an ideal handling in the production process. Depending on the country of origin, the colour varies from white to grey. Well known countries of origin are, for example, Turkey, China, Australia and New Zealand.

DIF | Innereien Symbol


Stomach, heparin, pancreas

DIF use intestines as supplement for the processing of casings for the production of sausages as so-called by-products from the slaughter process. Parts of these intestines provide raw materials for special medication such as pancreatin and heparin. In order to ensure an ideal use of the resource, other products are marketed as delicacies, mainly for the Asian market, after a quality orientated refinement in our company.
