Where Does Microcrystalline Cellulose Come from?

Microcrystalline cellulose (MCC) for industrial purposes is usually obtained from wood pulp and purified cotton linters. Each of these is a “natural” source, cotton is a high value-added crop and wood pulp generally originates in some manner from deforestation.

How is Microcrystalline Cellulose made?

Microcrystalline cellulose (Avicel, FMC Corporation) is prepared by acid hydrolysis of cellulose using 2 M hydrochloric acid at 105 °C for 15 min. The highly reactive amorphous regions selectively hydrolyze, releasing the crystallites, which are subsequently mechanically dispersed.

Is Microcrystalline Cellulose bad?

It is also found in many processed food products, and may be used as an anti-caking agent, stabilizer, texture modifier, or suspending agent among other uses. According to the Select Committee on GRAS Substances, microcrystalline cellulose is generally regarded as safe when used in normal quantities.
