How foods are produced, processed, fermented, cured and manufactured, and what those processes change.
Under EU law, mechanically separated meat (MSM) is obtained by recovering meat left on flesh-bearing bones after deboning or on poultry carcasses using mechanical means that cause loss or modification of muscle-fiber structure. It cannot simply be declared as ordinary “meat” in an EU ingredient list: the wording must identify mechanically separated meat and the animal species.
Acesulfame potassium, Ace-K, or E 950 is a high-intensity sweetener roughly 200 times sweeter than sucrose. It is heat-stable and used in drinks, desserts, sugar-free products, and baked foods. Manufacturers frequently blend it with other sweeteners because combinations can make sweetness feel more sugar-like and reduce bitter or metallic off-notes. EFSA raised its ADI to 15 mg/kg body weight per day in 2025.
Saccharin is one of the oldest high-intensity sweeteners. Its authorized forms and salts are grouped as E 954 in Europe and can be roughly 200–700 times sweeter than sucrose. It remains useful because it is inexpensive, stable, and needed only in tiny amounts. In 2024, EFSA raised its ADI to 9 mg/kg/day after concluding that the mechanism behind historical bladder tumors in male rats is not relevant to humans.
“Stevia” can mean a plant, purified steviol glycosides, or a tabletop product containing only a tiny amount of those glycosides blended with erythritol, dextrose, maltodextrin, or fiber. High-purity steviol glycosides are roughly 200–400 times sweeter than sucrose, so very little is needed. Reb A, Reb D, Reb M, stevioside, and other glycosides also have different sweetness and aftertaste profiles.
Sodium carboxymethylcellulose, also called cellulose gum or E 466, is made by chemically modifying cellulose so it disperses and dissolves much more effectively in water. It is used to thicken, stabilize emulsions and suspensions, retain moisture, and control ice crystals. EFSA found no need for a numerical ADI for general-population uses assessed, while a small controlled human trial found microbiome changes after 15 g/day for 11 days.
Guar gum (E 412) is a plant polysaccharide—a galactomannan—obtained from the endosperm of guar seeds. Its ability to hydrate rapidly and create high viscosity at low concentrations explains its use in sauces, ice cream, gluten-free baking, drinks, and processed foods. EFSA concluded that a numerical ADI was not needed for the general population at assessed uses, although high intakes can cause gastrointestinal symptoms.
Locust bean gum, also called carob bean gum (E 410), is a galactomannan extracted from the endosperm of carob seeds. It is used as a thickener and stabilizer because it binds water, improves body, and works especially well with carrageenan and xanthan. In ice cream it helps control ice-crystal growth and melting; in dairy it supports a more uniform texture.
Carrageenan (E 407) is a family of sulfated polysaccharides extracted from red seaweeds. Food manufacturers use small amounts to thicken, gel, and keep protein, cocoa, minerals, or other particles from separating. Kappa, iota, and lambda carrageenan behave differently. Food-grade carrageenan should not be confused with poligeenan, a degraded low-molecular-weight material that is not authorized as a food additive.
Under U.S. FDA rules, “natural flavor” covers flavoring constituents derived from plant, animal, dairy, seafood, egg, yeast, or fermentation sources using processes such as extraction, distillation, roasting, heating, or enzymolysis. The significant function must be flavoring rather than nutritional. The term says little by itself about calories, sugar, processing level, or overall food quality.
Creatine monohydrate is creatine in a crystalline form associated with one molecule of water. It is not a diluted or inferior version: it is the form used in most creatine trials. Systematic reviews have not found consistent evidence that alternative forms improve performance, body composition, or bioavailability beyond monohydrate.
Protein cereal usually gets its extra protein from added soy, wheat, pea, milk, or other concentrated protein ingredients. Current products can provide about 15 g per serving or 20–36 g per 100 g, far above many conventional cereals. But 'protein' does not automatically mean lower sugar, higher fiber, fewer calories, or a simpler ingredient list.
Apple cider vinegar is made through two fermentations: yeasts convert apple sugars to alcohol, then acetic-acid bacteria convert that alcohol to acetic acid. The “mother” is a cellulose-rich matrix associated with acetic-acid bacteria and fermentation material. Its presence signals a less-filtered product, but solid clinical evidence does not show that the mother makes the vinegar medically superior.
