Co-Ext rus ion. What is i t?
Co-Extrusion definition: “Simultaneous flow of multiple components”
Translated to sausage product : “Simultaneous flow of one or two meat / sauce
mixes and an encasing product”
![Page 6: CO-EXTRUSION SYSTEMS USING ALGINATE](https://reader036.fdocuments.in/reader036/viewer/2022081614/62c9965429e89d033f667cd3/html5/thumbnails/6.jpg)
An All Natural Vegetable Casing
used in a continuous sausage
production line with
extremely low yield loss and
give away creating a very
cost effective product.

Alginate Reaction
Na-Alginate + Ca2+ Ca-Alginate + Na+ Paste Gel = Skin
• Equilibrium • Very Fast Reaction
• Attention give to Stability • Ions in meat dough can attack the casing (mainly sodium/potassium ions, phosphates, citrates)
![Page 27: CO-EXTRUSION SYSTEMS USING ALGINATE](https://reader036.fdocuments.in/reader036/viewer/2022081614/62c9965429e89d033f667cd3/html5/thumbnails/27.jpg)
Solution – Stabilizing Alginate Skin
Introducing Ca2+ in meat system
Addition of Ca-lactate/Ca-acetate/CaCl2 in meat Introducing Ca2+ in production process
Addition of Ca Source (Ca-lactate/CaCl2) in bath/smoke/cooking water/chilling water
New VegaCasing Development
3 rd Generation of Casings (Internal Stabilization)
