Extrusion and Co-extrusion: A Technology in Probiotic Encapsulation with Alternative Materials

Current Pharmaceutical Biotechnology
: Encapsulation, in particular extrusion and co-extrusion, is a common practice to protect probiotics from the harsh conditions of the digestive tract as well as processing. Hydrocolloids, including proteins and carbohydrates, natural or modified, are a group of ingredients used as the wall material in extrusion.

Extrusion Rheometry of Fluid Materials

Journal of Dental Research, 1979
A capillary extrusion rheometer was developed and tested using Newtonian oils of known viscosity and seven endodontic sealers. The described ap paratus and technique appear appropriate for com parative assessment of the rheological characteristics of a variety of fluid dental materials.

Recent Developments in Mechanochemical Materials Synthesis by Extrusion

Advanced Materials, 2016
Mechanochemical synthesis, i.e., reactions conducted by grinding solid reactants together with no or minimal solvent, has been demonstrated as an excellent technique for the formation of both organic and inorganic compounds. Mechanochemistry is viewed as an alternative approach to chemical synthesis and is not always considered when developing ...

Extrusion behavior of viscoelastic materials

Journal of Colloid Science, 1950
Abstract The relation between viscoelastic properties and extrusion characteristics is discussed. It is shown that materials characterized by nonlinear deformation-time properties necessarily exhibit a nonlinear relation between volume rate of discharge and pressure in extrusion.

Force controlled printing for material extrusion additive manufacturing

Additive Manufacturing
In material extrusion additive manufacturing, the extrusion process is commonly controlled in a feed-forward fashion. The amount of material to be extruded at each printing location is pre-computed by a planning software.
