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.

Oat Fiber: What It Is and Why It Is Not the Same as Oat Bran or Oat Flour

The oat fiber listed in high-fiber foods is commonly oat-hull fiber rather than oat flour or bran. FDA describes oat hull fiber as isolated from the outer hull removed from the edible oat groat and generally containing at least about 85% nondigestible carbohydrate, mostly insoluble cellulose and hemicellulose. This makes it very different from bran or flour, which still contain substantial starch, protein, and beta-glucan.

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.

Isomalt: What It Is, How Many Calories It Has, and How It Differs From Isomaltulose

Isomalt is a bulk sugar alcohol used mainly in hard candy, decorative sugar work, and sugar-free confectionery. It is manufactured from sucrose: sucrose is first converted to isomaltulose and then hydrogenated into a mixture of polyols. FDA uses 2 kcal/g for U.S. labeling. Unlike isomaltulose, isomalt is not fully digested and larger amounts can produce laxative gastrointestinal effects.

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.

Agave Syrup: Why It Is High in Fructose and Whether Its Glycemic Index Is Lower

Agave syrup is produced by converting fructans stored in the agave plant into smaller sugars and concentrating the resulting liquid. Many products end up particularly rich in fructose. Because fructose does not raise blood glucose immediately as much as glucose does, agave can have a lower glycemic index than sucrose. That difference does not remove its calories or make a high intake of concentrated sweetener metabolically advantageous.

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.
