class=skin-invert-image|thumb|Callose is an example of a (1→3)-β-D-glucan composed of [[glucose units]] Beta-glucans, β-glucans comprise a group of β-D-glucose polysaccharides (glucans) naturally occurring in the cell walls of plants (including cereals), bacteria, algae and fungi, with significantly differing physicochemical properties dependent on source. Typically, β-glucans form a linear backbone with 1–3 β-glycosidic bonds but differ with respect to molecular mass, solubility, viscosity, branching structure, and gelation properties, with several physiological roles in these organisms and c

β-Fructofuranosidase is an enzyme that catalyzes the hydrolysis (breakdown) of the table sugar sucrose into fructose and glucose. Sucrose is a fructoside. Alternative names for β-fructofuranosidase include invertase, saccharase, glucosucrase, β-fructosidase, invertin, fructosylinvertase, alkaline invertase, and acid invertase. The resulting mixture of fructose and glucose is called inverted sugar syrup. Related to invertases are sucrases. Invertases and sucrases hydrolyze sucrose to give the same mixture of glucose and fructose. Invertase is a glycoprotein that hydrolyses (cleaves) the non-red

Simeticone (INN), also known as simethicone (USAN), is an anti-foaming agent used to reduce bloating, discomfort or pain caused by excessive gas.

chemical compound

Neotame, also known by the brand name Newtame, is a non-caloric artificial sweetener and aspartame analog. By mass, it is 7,000 to 13,000 times sweeter than sucrose. It has no notable off-flavors when compared to sucrose. It enhances original food flavors. It can be used alone, but is often mixed with other sweeteners to increase their individual sweetness (i.e. synergistic effect) and decrease their off-flavors (e.g. saccharin). It is chemically somewhat more stable than aspartame. Its use can be cost effective in comparison to other sweeteners as smaller amounts of neotame are needed.

Transglutaminases are enzymes that in nature primarily catalyze the formation of an isopeptide bond between γ-carboxamide groups ( -(C=O)NH2 ) of glutamine residue side chains and the ε-amino groups ( -NH2 ) of lysine residue side chains with subsequent release of ammonia ( NH3 ). Lysine and glutamine residues must be bound to a peptide or a protein so that this cross-linking (between separate molecules) or intramolecular (within the same molecule) reaction can happen. Bonds formed by transglutaminase exhibit high resistance to proteolytic degradation (proteolysis). The rea

Estragole ('''p-allylanisole, methyl chavicol''') is a phenylpropene, a natural organic compound. Its chemical structure consists of a benzene ring substituted with a methoxy group and an allyl group. It is an isomer of anethole, differing with respect to the location of the double bond. It is a colorless liquid, although impure samples can appear yellow. It is a component of various trees and plants, including turpentine (pine oil), anise, fennel, bay, tarragon, and basil. It is used in the preparation of fragrances. Its aroma is described as "sweet, sassafras, anise, spicy, green, herbal, fe

Ractopamine () is an animal feed additive used to promote leanness and increase food conversion efficiency in farmed animals in few countries, banned in most. Pharmacologically, it is a phenol-based TAAR1 agonist and β adrenoreceptor agonist that stimulates β1 and β2 adrenergic receptors. It is most commonly administered to animals for meat production as ractopamine hydrochloride. It is the active ingredient in products marketed in the US as Paylean for swine, Optaflexx for cattle, and Topmax for turkeys. It was developed by Elanco Animal Health, a former division of Eli Lilly and Company.

Azodicarbonamide, ADCA, ACA, ADA, or 'azo(bis)formamide', is a chemical compound with the molecular formula . It is a yellow to orange-red, odorless, crystalline powder. It is sometimes called "the yoga mat chemical" because of widespread use in foamed plastics. It was first described by John Bryden in 1959.

Alitame is an aspartic acid-containing dipeptide sweetener. It was developed by Pfizer in the early 1980s and currently marketed in some countries under the brand name Aclame. Most dipeptides are not sweet, but the unexpected discovery of aspartame in 1965 led to a search for similar compounds that shared its sweetness.

Dimethylglycine (DMG) is a derivative of the amino acid glycine with the structural formula (CH3)2NCH2COOH. It can be found in beans and liver, and has a sweet taste. It can be formed from trimethylglycine upon the loss of one of its methyl groups. It is also a byproduct of the metabolism of choline.

Chlorophyllin refers to any one of a group of closely related water-soluble salts that are semi-synthetic derivatives of chlorophyll, differing in the identity of the cations associated with the anion. Its most common form is a sodium/copper derivative used as a food additive and in alternative medicine. As a food coloring agent, copper complex chlorophyllin is known as natural green 3 and has the E number E141.

thumb|right|250px|Dosage of defoamer A defoamer or an anti-foaming agent is a chemical additive that reduces and hinders the formation of foam in industrial process liquids. The terms anti-foam agent and defoamer are often used interchangeably. Strictly speaking, defoamers eliminate existing foam and anti-foamers prevent the formation of further foam. Commonly used agents are insoluble oils, polydimethylsiloxanes and other silicones, certain alcohols, stearates and glycols. The additive is used to prevent formation of foam or is added to break a foam already formed.

An adulterant is a substance discreetly added to another that may compromise the safety or effectiveness. Consumable products, such as food, cosmetics, pharmaceuticals and fuels, are frequently adulterated to reduce the cost or difficulty of production without the knowledge of the buyer, allowing the product to be sold at the same price as a chemically pure equivalent. The adulteration of street drugs is known as lacing.

Pullulan is a polysaccharide consisting of maltotriose units, also known as α-1,4- ;α-1,6-glucan'. Three glucose units in maltotriose are connected by an α-1,4 glycosidic bond, whereas consecutive maltotriose units are connected to each other by an α-1,6 glycosidic bond. Pullulan is produced from starch by the fungus Aureobasidium pullulans. Pullulan is mainly used by the cell to resist desiccation and predation. The presence of this polysaccharide also facilitates diffusion of molecules both into and out of the cell.

Acetanisole is an organic compound with the formula . It can be viewed as derivative of acetophenone and of anisole. It has an aroma described as sweet, fruity, nutty, and similar to vanilla. In addition the odor of acetanisole is sometimes described as butter-like or caramel-like. It is used commercially in some soap fragrances. It is a component of anise oil.
