Polysaccharides 718<br />

NAME: Microcrystalline cellulose<br />

CATEGORY: Polysaccharides<br />

FOOD USE: Low-fat salad creams/ Low-fat meat spreads/ Dry formulated products/ Low-calorie foods/<br />

Confectionery processing aid/ All food products<br />

SYNONYMS: Beta-D-(1Æ4) glucan/ CAS 9004-34-6/ EINECS 232-674-9/ E460/ cellulose gel/ Avicel<br />

FORMULA: (C6 H10 O5)n<br />

MOLECULAR MASS: Variable<br />

ALTERNATIVE FORMS: None<br />

PROPERTIES AND APPEARANCE: A white powder or gel<br />

SOLUBILITY % AT VARIOUS Microcrystalline cellulose is insoluble in water, but commercial preparations are generally colloidal<br />

TEMPERATURE/pH COMBINATIONS: mixtures of microcrystalline cellulose and carboxymethyl cellulose that can be dispersed in aqueous<br />

solutions<br />

FUNCTION IN FOODS: Can be used as a processing aid; fat mimetic; dietary fibre; thickening agent; stabiliser; bulking agent.<br />

It is not digestible and so can be used in low-calorie preparations<br />

ALTERNATIVES: Starch hydrolysis products (SHPs); polydextrose; xanthan (application-dependent)<br />

TECHNOLOGY OF USE IN FOODS: Microcrystalline cellulose can be dispersed in cold water. Mixing with a high shear mixer could change<br />

the physical properties of the preparation.<br />

Commercial preparations of microcrystalline cellulose consist of fine particles of crystalline<br />

cellulose mixed with carboxymethyl cellulose. The fine cellulose particles simulate the mouthfeel of fat<br />

crystals, whereas the carboxy methyl cellulose lubricates the particles and provides thickening<br />

properties<br />

SYNERGISTS: None known<br />

ANTAGONISTS: None known
