Powdered and Microcrystalline Cellulose: What They Are and Why They Appear in Food

Powdered cellulose and microcrystalline cellulose are purified forms of cellulose, the major structural polysaccharide in plant cell walls. Powdered cellulose is produced mainly through fine mechanical pulverization of purified cellulose, while microcrystalline cellulose receives partial hydrolysis that removes more amorphous regions. Both are used for physical functionality such as anticaking, stabilization, bulking, and texture rather than sweetness.

Soluble Tapioca Fiber: What It Is and How It Differs From Tapioca Starch

Soluble tapioca fiber is not simply tapioca starch under another name. It is commonly a resistant dextrin manufactured from cassava starch through hydrolysis and rearrangement of glucose linkages so that much of the material resists digestive enzymes. Conventional tapioca starch, by contrast, gelatinizes when heated and is largely digested to glucose. The difference is the structure created during processing.

Citrus Fiber: What It Is, Where It Comes From, and Why It Is Used in So Many Foods

Citrus fiber is an ingredient made mainly from the peel, albedo, and pulp left after citrus juice processing. Washing, drying, and milling produce a dietary-fiber-rich material containing pectin, cellulose, and hemicellulose in varying proportions. Its value is not only nutritional: citrus fiber can bind substantial water and oil, increase viscosity, and stabilize food structures, which is why it appears across many product categories.

Glycerol or Glycerin in Food: What It Is and Why It Is Used as a Humectant

Glycerol and glycerin are two names for the same compound. It is a small three-carbon molecule that occurs naturally as the backbone of triglycerides in fats and oils. In foods it is especially useful because it is hygroscopic, meaning it attracts and holds water. This helps keep baked goods, bars, fillings, and confectionery soft. It can also function as a solvent, carrier, stabilizer, and nutritive sweetener.

Lactitol: What It Is, Why It Is Used as a Sweetener, and What It Does in the Gut

Lactitol is a sugar alcohol produced by hydrogenating lactose. It is much less sweet than sucrose and is poorly absorbed in the small intestine, making it useful as a lower-energy bulking sweetener. FDA uses 2 kcal/g for U.S. labeling. Most of the dose reaches the colon for fermentation, which explains both its lower energy value and its laxative potential at sufficiently high intake.

Date Sugar: What It Is and How It Differs From Sugar and Date Syrup

“Date sugar” commonly refers to dried dates ground into powder, although commercial terminology is not perfectly standardized. When the product is whole dried fruit, it retains some fiber, minerals, and polyphenols from the date. It is still highly concentrated in naturally occurring sugars, especially glucose and fructose. Date syrup is produced differently by extracting soluble sugars and concentrating the liquid.

Rice Syrup: What It Is, How It Is Made, and What to Know About Arsenic

Rice syrup is a sweetener made by breaking down rice starch with enzymes and concentrating the soluble sugars produced. It commonly contains maltose, glucose, and short glucose chains, with little or no fructose depending on processing. The best-known safety question is arsenic: rice can accumulate more inorganic arsenic than many other grains, and some can carry into rice-derived ingredients, although concentrations vary widely among raw materials and products.

Isomaltooligosaccharides (IMO): What They Are and Why They Do Not Always Count as Fiber

Isomaltooligosaccharides, or IMO, are mixtures of short glucose chains that commonly contain alpha-1,6 and alpha-1,4 linkages. Many commercial ingredients are produced from starch through hydrolysis and transglucosylation. Although part of an IMO mixture may resist digestion, another part can be hydrolyzed and absorbed as glucose. This is why different IMO syrups can have very different true fiber content and glycemic effects.

Resistant Dextrin: What It Is, Why It Counts as Fiber, and Where It Appears

Resistant dextrin is a starch-derived glucose polymer in which processing creates bonds that human digestive enzymes cannot easily break. Unlike conventional maltodextrin, a substantial fraction reaches the colon. Because it is soluble, stable, and low-viscosity, manufacturers can add several grams to drinks or foods without creating a thick gel. FDA recognizes the resistant dextrin/resistant maltodextrin category as dietary fiber.

Maltodextrin: What It Is, Why It Is Used, and How It Affects Blood Glucose

Maltodextrin is a carbohydrate made by partially breaking down starch from corn, potato, rice, wheat, or other sources into shorter glucose chains. It dissolves easily, is only mildly sweet, and works well for adding body, carrying flavors, drying ingredients, and providing rapidly available carbohydrate. Unlike resistant dextrin, ordinary maltodextrin is readily digested and can raise blood glucose quickly.

Polydextrose: What It Is, Why It Is Used as Fiber, and What It Can Do in the Gut

Polydextrose is a highly branched glucose polymer manufactured so human digestive enzymes cannot easily break most of its bonds. It supplies bulk with little sweetness and relatively little energy, making it useful for adding fiber and replacing part of the sugar or fat in bars, desserts, drinks, and lower-calorie foods. In the colon it is fermented relatively slowly and can influence microbial activity and bowel function.
