Food thickening agents: Sources, chemistry, properties
Thickening agents or thickeners, are substances from different sources, which are widely used for modification of rheological and textural properties of food. It is common for these hydrophobes to be linked to the chain by means of polyoxyethylene spacer groups. Commercially available associative thickeners are usually classified as Thickening Agent an overview ScienceDirect Topics

Essential Chemistry for Formulators of Semisolid and Liquid
Abstract. Rheology is the study of how materials deform and flow as a result of an external force, and is one tool that is used by formulators to help characterize semisolid dosage forms. The two extremes of rheological behavior are elastic and viscous (or Premixtures for food production are complex mixtures typically containing thickeners due to their water binding capacity. Here, we report an improved protocol for the fast identification of food thickeners by 1 H-NMR spectroscopy. The method is based on four steps: (i) dissolving of the dry premixture in water, (ii) centrifugation of the solution NMR-based identification of thickeners in membrane-filtered

3.2: Basic Facts About Calcium- Its Compounds and Reactions
Essentials of Ca 2 + Chemistry. Since the Ca 2 + ion accomplishes its biological tasks in an environment with 1 to 3 mM Mg 2 +, it is of particular interest to compare the properties of these two ions in order to understand how a discrimination is made in biological systems.In addition, the coordination chemistry of Ca 2+ is closely related to that of Mg 2+ (as well Soaps (comprising about 90 percent of all greases used) Lithium: Because lithium soaps are very efficient thickeners, lithium 12-hydroxystearate greases are the most prevalent. Lithium greases provide good lubricity and have great shear stability, thermal resistance and relatively low oil separation.

Grease chemistry is governed by thickener
Types of thickeners. The thickener defines the type of grease. There are three or four different types of materials that go into thickeners. The focus in this article is on organic thickeners such as The flow and dynamic rheological results showed that the flow and viscoelastic properties of the thickened PBB samples prepared with different food thickeners were dependent on the PBB type, thickener type, and setting time.
