Study Notes

Sweeteners

Provide less than 2% of the caloric value of sucrose per equivalent unit of sweetening capacity when used to sweeten food.
Examples: sorbitol, mannitol, aspartame (fruit flavor), acesulfame-k.
Used in: chocolates, ice cream, pastries, jams, drinks.

Enzymes

Function: digestion and clarification.
Examples: pepsin, rennet, papain, amylase, pectinase.
Used in: cheese making, tenderizing meat, beverage clarification.

Neutralizing Agents

Function: to remove excess acidity.
Examples: alkaline salts of Na, K, Mg, and Ca.
Used in: wine, ice cream.

Stabilizing Agents

Function: to ensure a stable emulsion.
Examples: carageenan gums, gum arabic, calcium citrate.
Used in: chocolate milk, ice cream, foam stabilizer in beer.

Firming Agents

Function: to retain texture of canned fruit and vegetables.
Examples: CaCO3, sodium aluminium sulphate, calcium citrate.
Used in: canned tomatoes.

Flour Improvers

Function: for bleaching and dough toughening.
Examples: benzoyl peroxide, chlorine gas, ClO2.
Used in: flour.

Humectants

Function: to prevent undesirable drying of foods and maintain moisture level.
Examples: glycerin, sorbitol, mannitol, dextrose, and corn syrup.
Used in: shredded coconut.

Sequestrants (Chelating Agents)

Function: to prevent deterioration of food due to free metallic ions.
Examples: Ca-EDTA, phosphates like KH2PO4, organic acids like tartaric acid and citric acid.
Used in: soft drink industries, malted beverages.

Antioxidants

Function: to prevent flavor and color changes, and retard rancidity.
Examples: lecithin, vitamin C, tocopherols, citric acid, tartaric acid, and gallic acid.
Used in: dry mix, rasogollas, vadas, ghee, and butter, edible oils and fats.

Anticaking and Free-Flowing Agents

Function: to prevent lumping and caking, and absorb moisture.
Examples: carbonates and phosphates of Ca and Mg, silicates of Ca, Mg, Al, and Na.
Used in: table salt, instant mix.
