Nanocellulose is a term referring to a family of cellulosic materials that have at least one of their dimensions in the nanoscale. Examples of nanocellulosic materials are microfibrilated cellulose, cellulose nanofibers or cellulose nanocrystals. Nanocellulose may be obtained from natural cellulose fibers through a variety of production processes.
Cellulose is used to make water-soluble adhesives and binders such as methyl cellulose and carboxymethyl cellulose which are used in wallpaper paste. Cellulose is further used to make hydrophilic and highly absorbent sponges. Cellulose is the raw material in the manufacture of nitrocellulose (cellulose nitrate) which is used in smokeless gunpowder.
Curran is a microcrystalline nanocellulose fibre derived from the pulp of root vegetables. It was developed by Scottish scientists David Hepworth and Eric Whale, with funding from the Scottish Government. The sources of root vegetable pulp used to manufacture Curran include carrots, sugar beets, and turnips.
Studies have shown that the plant’s extract consists of anti-melanogenesis activity by activating Akt/GSK-3b and interrupting maturation of tyrosinase by inhibiting a-glucosidase. [21] Additionally, research has been done to examine the use of Pueraria montana var. lobata nanocellulose as a sustainable packaging material. [22]
Nanocellulose is instead derived from wood pulp that has been processed to create extremely small, nanoscale fibers. These fibers can be used to create a hydrogel, which is a type of material that is made up of a network of cross-linked polymer chains and is able to hold large amounts of water.

While many plants have been used for food, a small number of staple crops including wheat, rice, and maize provide most of the food in the world today. In turn, animals provide much of the meat eaten by the human population, whether farmed or hunted, and until the arrival of mechanised transport, terrestrial mammals provided a large part of the ...
Carboxymethyl cellulose (CMC) or cellulose gum [1] is a cellulose derivative with carboxymethyl groups (-CH 2-COOH) bound to some of the hydroxyl groups of the glucopyranose monomers that make up the cellulose backbone. It is often used in its sodium salt form, sodium carboxymethyl cellulose. It used to be marketed under the name Tylose, a ...
Edible plants have long been a source of nutrition for humans, and the reliable provision of food through agriculture and horticulture is the basis of civilization since the Neolithic Revolution. Medicinal herbs were and still remain to be the key ingredients of many traditional medicine practices, as well as being raw materials for some modern ...
