Chemical Modification of Polysaccharides Using Reactive Extrusion
Sodium carboxymethyl starch (CMS) was prepared using an extruder as a continuous solvent-less chemical reactor. The effects of NaOH, H2O, temperature, ethanol, sodium mono chloro acetate (SMCA), sodium tripolyphosphate (STPP), citric acid, epichlorohydrin and screw configuration on the degree of substitution (DS) and swelling properties of CMS were studied. Using these factors, CMS with the DS ...
متن کاملThermoplastic Extrusion in Food Processing
Extrusion cooking was first introduced in food and feed processing in the late 1950s. Since then, the systems involved have grown in popularity, efficiency and flexibility. Extrusion cooking technology is most used for cereal and protein processing in the food industry and is closely related to the pet food and feed sectors. In the last decade, the development of extruders has evolved to yield ...
متن کاملDirect bonding technology by chemical reactions at the interface & the applications of polyamide elastomers (PEBA)
Thermoplastic polyamide elastomer (PAE) [also PEBA: polyether block amide] is one of the most recently developed of the thermoplastic elastomers: a multiblock polymer with polyamide hard segments, it uses longchain polyether diol or polyester diol of low Tg for its soft segments. Polyamide 6 or polyamide 12 (PA12) is the main polyamide component used, while the soft segments are mostly provided...
متن کاملPhysical and/or Chemical Modifications of Starch by Thermoplastic Extrusion
Starch makes up the nutritive reserves of many plants. Starch biosynthesis is a complex process, which may be summarized as during the growing season, the green leaves collect energy from the sun, this energy is transported as a sugar solution to the starch storage cells, and the sugar is converted into starch in the form of tiny granules occupying most of the cell interior. The conversion of s...
متن کاملEnhanced Coarse-Graining of Thermoplastic Polyurethane Elastomer for Multiscale Modeling
The objective of this work is to develop a multiscale modeling tool of copolymers with long chains. We propose an enhanced coarse-graining method of thermoplastic polyurethane (TPU) with three beads. The proposed coarse-graining provides an accurate molecular modeling tool to keep the molecular interaction together with computational efficiency. The coarse-grained model with three beads is furt...
