Most bulk food ingredients, eg, flour, fats and oils, and nutritive sweeteners (qv) such as sugar (qv), are excluded from the food additive category. In a few cases, substances that are used in relatively large quantities, eg, dietary fiber (qv) and bulking agents, are included herein because these have been the focus of market and technology developments. 

Metamucil is a popular bulking agent for use ia the chronic therapy of several gastroiatestiaal disorders. It is also iadicated for use when a high fiber iatake is recommended. 

The above chemicals can be obtained by fermentation (qv) of other sugars. However, some compounds require sucrose as a unique feedstock. Examples are the polysaccharides dextran, alteman, andlevan, which are produced by specific strains of bacteria (48,54—56). Dextrans are used to make chromatographic separation media, and sulfated dextran derivatives are used as plasma extenders (41). Levans show promise as sweetness potentiators and, along with alteman, have potential as food thickeners and bulking agents in reduced-caloric foods (55,56) (see Carbohydrates). 

Treatment of ceUulose with acids results in preferential hydrolysis in the more accessible amorphous regions and produces a product known as microcrystalline ceUulose (MCC). MCC is used to prepare fat-free or reduced-fat food products, to strengthen and stabilize food foams, as a tableting aid, and as a noncalotic bulking agent for dietetic foods. It has GRAS status. 

Many plant products are very rich in cell wall materials. Cereal brans, seed hulls, various pulps (including beet pulp), citrus peels, apple pomace... are typical exemples of such by-products (1,2). They can be used after simple treatments as dietary fibres, functional fibres or bulking agents, depending on the nutritional claims (2). They can be used also eis sources of some polysaccharides. 

Composting. This is an aerobic, thermophilic treatment process in which contaminated material is mixed with a bulking agent it can be carried out using static piles or aerated piles. 

Hydrofluoric acid is an important refrigerant and it is used as a bulking agent in foam industries. It is widely used in the aluminum production industry, nuclear fuel, steel, petroleum refining, and fluoride salt production. 

All foodstuffs in the area of a release should be considered contaminated. Unopened items packaged in glass, metal, or heavy plastic and exposed only to aerosols may be used after decontamination of the container. All unopened items exposed to bulk agents should be decontaminated within a few hours postexposure or destroyed. Opened or unpackaged items, or those packaged only in paper or cardboard, should be destroyed.
