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.

POTASSIUM NITRATE is a chemical compound with the chemical formula KNO3. The widespread adoption of nitrate use is more recent and is linked to the development of large-scale meat processing. potassium nitrate is still used in some food applications, such as salami, dry-cured ham, charcuterie.

Sodium triphosphate (STP), also sodium tripolyphosphate (STPP), or tripolyphosphate (TPP),) is an inorganic compound with formula Na5P3O10. It is the sodium salt of the polyphosphate penta-anion, which is the conjugate base of triphosphoric acid. It is produced on a large scale as a component of many domestic and industrial products, especially detergents. Environmental problems associated with eutrophication are attributed to its widespread use.

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.
