Dextrins are a group of low-molecular-weight carbohydrates produced by the hydrolysis of starch or glycogen. Dextrins are mixtures of polymers of D-glucose units linked by α-(1→4) or α-(1→6) glycosidic bonds. Dextrins can be produced from starch using enzymes like amylases, as during digestion in the human body and during malting and mashing, or by applying dry heat under acidic conditions (pyrolysis or roasting). The latter process is used industrially, and also occurs on the surface of bread during the baking process, contributing to flavor, color and crispness. Dextrins produced by heat are also known as pyrodextrins. The starch hydrolyses during roasting under acidic conditions, and short-chained starch parts partially rebranch with α-(1,6) bonds to the degraded starch molecule. See also Maillard Reaction. Dextrins are white, yellow, or brown powders that are partially or fully water-soluble, yielding optically active solutions of low viscosity. Most of them can be detected with iodine solution, giving a red coloration; one distinguishes erythrodextrin (dextrin that colours red) and achrodextrin (giving no colour). White and yellow dextrins from starch roasted with little or no acid are called British gum.

Monosodium glutamate (MSG), or E621, is the sodium salt of glutamic acid, an amino acid found naturally in many foods.

It is widely used as a flavor enhancer to provide an "umami" or savory taste to a variety of processed foods, including soups, snack chips, and frozen meals.

MSG is generally recognized as safe (GRAS) by food authorities. However, some people report sensitivity to MSG, experiencing short-term symptoms like headaches and flushing, though scientific studies have not shown a consistent link.

Sodium saccharin (benzoic sulfimide) is an artificial sweetener with effectively no food energy. It is about 300–400 times as sweet as sucrose but has a bitter or metallic aftertaste, especially at high concentrations. Saccharin is used to sweeten products such as drinks, candies, cookies, and medicines.

Steviol glycosides are the chemical compounds responsible for the sweet taste of the leaves of the South American plant Stevia rebaudiana (Asteraceae) and the main ingredients (or precursors) of many sweeteners marketed under the generic name stevia and several trade names. They also occur in the related species Stevia phlebophylla (but in no other species of Stevia) and in the plant Rubus chingii (Rosaceae).Steviol glycosides from Stevia rebaudiana have been reported to be between 30 and 320 times sweeter than sucrose, although there is some disagreement in the technical literature about these numbers. They are heat-stable, pH-stable, and do not ferment. Additionally, they do not induce a glycemic response when ingested, because humans can not metabolize stevia. This makes them attractive as natural sugar substitutes for diabetics and other people on carbohydrate-controlled diets. Steviol glycosides stimulate the insulin secretion through potentiation of the β-cell, preventing high blood glucose after a meal. The acceptable daily intake (ADI) for steviol glycosides, expressed as steviol equivalents, has been established to be 4 mg/kg body weight/day, and is based on no observed effects of a 100 fold higher dose in a rat study.
