Because of the strong hydrogen bonds that occur between cellulose chains, cellulose does not melt or dissolve in common solvents. Thus, it is difficult to convert the short fibers from wood pulp into the continuous filaments needed for artificial silk, an early goal of cellulose chemistry. he existence of cellulose as the common material of plant cell walls was first recognized by Anselm Payen in 1838. It occurs in almost pure form in cotton fiber and in combination with other materials, such as lignin and hemicelluloses, in wood, plant leaves and stalks, etc.
Cellulose is virgin wood pulp whose variant forms (cellulose gum, powdered cellulose, microcrystalline cellulose, etc.) are deemed safe for human consumption by the FDA, but the agency sets no limit on the amount that can be used in food products, as it does with other contaminants.ellulose adds fiber to the food, which is good for people who do not get the recommended daily intake of fiber in their diets, Inman said. It also extends the shelf life of processed foods. Plus, cellulose's water-absorbing properties can mimic fat, he said, allowing consumers to reduce their fat intake.
