In addition to plant fiber materials, Alfa Chemistry is also committed to providing customers with a series of plant fiber component chemicals, including cellulose, hemicellulose, lignin, pectin and their derivatives.
Introduction
- Cellulose is a macromolecular polysaccharide composed of glucose and is the main component of plant cell walls.
- Hemicelluloseis a heteropolymer composed of several different types of monosaccharides bound to the surface of cellulose microfibrils and interconnected. These fibers form an interconnected network of tough cells.
- Lignin is an aromatic high polymer composed of oxophenylpropanol or its derivative structural units, forming a fiber scaffold, which has the effect of strengthening wood fibers.
- Pectin is a kind of natural macromolecular compound fiber, which is an important supporting material of plant cell interstitium.
Research and Application
- Cellulose
Cellulose and its derivatives have the advantages of good biocompatibility, renewable and biodegradable properties. They have been widely researched and applied in the fields of medicine, coatings, membrane technology, aerospace, new energy and high-end electronic devices. [1] - Hemicellulose
Hemicellulose contains functional groups such as hemicellulose hydroxyl, acetyl and carboxyl groups, which can be cross-linked or further modified to form hemicellulose-based hydrogels with different functions. Hemicellulose has been expanded for applications in biology, medicine, wounds, dressings, wastewater treatment, and 3D printing. - Lignin
Because of its three-dimensional network structure, suitable carbon-hydrogen ratio, phenolic hydroxyl group, rigid benzene ring and carbonyl structure that can provide a lot of activity, lignin is a kind of adsorption, thermal aging resistance, oxidation resistance, high temperature deformation resistance. It is ideal material for various functions such as biocompatibility. - Pectin
Some specific sources of pectin can be used as natural multifunctional food additives, which are used as gelling agents, thickening agents, emulsifiers, stabilizers, etc.
