Chemistry of 20 most used food additives in food industry
The pursuit of happiness through the enjoyment of having or eating and cooking food was dates back from out ancient civilizations. The process of cooking was started by our ancestors Neanderthals.
Ancient civilizations like Roman civilizations, Greece civilizations, Egyptian civilizations, Chinese civilizations, Indian civilizations will show the different food styles ranging from having raw food to usage of sulfur to seal wine packing to using herbs, spices for cooking.
Even though different food cooking styles, shelf life of food is crucial and even more qualities required for tastier food. Additional products which are required to do these activities are called food additives.
Without food additives Foods will be
- Taste less
- No texture
- No shape
- No flavor
- No freshness
- No alkalinity
- No acidity
- No proper ph value
- Infected with bacteria
Food additives are defined as
“It is any chemical whether natural in origin or synthetic which is not normally taken as a food or consumed as a food instead they are added to food products to enhance quality and desirable properties of food.”
Food additives may not be providing any nutritional value to food products but food additives are added intentionally to boost food qualities either of directly or indirectly.
Based on direct or indirect effects of food additives in food products they are classified as
- Direct food additives
- Indirect food additive

Out of 2300 food additives, each food additives has their own property which impart to food products.
Some food additives are used
Anticaking Agents mainly used to prevent lumps, deicing foods. Anticaking Agents are added to foods, fertilizers, salts, cosmetics in small portions. These additives works by absorbing moisture content in foods and by water repelling property
Antifoaming agent is mainly used to prevent foam formation and for reducing surface tension in foods. Antifoaming agents also used in coke, sprite and other carbonated soft drinks. These are used in drugs to reduce bloating.
Food Emulsifiers will make food as appealing appearance. Food Emulsifiers are the major effective food additives of structure, texture, taste, quality and freshness of foods. It also acts as unmixable agent between oil and water component of some foods. Food Emulsifiers often termed as emulgents.
Firming agents are food additives and these are added to fruits, vegetables, canned foods, pickles to keep firm or crispy, structure. Calcium chloride as a firming agent can be used in canned vegetables, in firming soy bean curd.
Flavor Enhancers are commonly used for luscious foods to boost the existing flavor in the food. Flavor Enhancers customize flavors, stability of pepsi, pizza dough and other types of foods without contributing to any significant flavor of their own.
Flour treatment agents intensify texture, strength, softness, crumb structure and color of bread loafs. Ascorbic acid is the commonly used flour treatment agent. Flour treatment agents keep homogenous appearance during fermentation process.
Food acids are found in natural sources like orange, lemon, berries, and plumps. Citric acid, maleic acid and tartaric acid are the best known common food acids. These imparts different flavor, tinge to foods. Some times food acids may acts as antioxidants, preservatives.
Gelling agent are commonly added to food to impart gel texture. Gelling agents also gives shape, structure to foods. Gelatin, pectin are regarded as common gelling agents. Gelling agents sometimes called as solidifiers.
Food Glazing Agents also referred as polishing agents. Food Glazing Agents are providers of shiny, homogenous, waxy and surface protection. Beeswax and lanolin are the most common food glazing agents.
Humectants are food additives which primarily retain and preserve moisture content of food and cosmetic products. Humectants also used in tobacco products, coatings for plastics, skin care products, body lotions, hair conditioners. Glycerine, sorbitol, propylene glycol are the examples of humectants.
Preservatives prevent chemical changes, microbial growth of foods, wood, pharmaceuticals, paints, biological samples and retain flavor and nutritional values of food for a longer time. Food preservatives like sodium benzoate, potassium benzoate, calcium sorbate, and glycolic acids are common examples.
Propellants are commonly used in whipped creams, carbonated drinks. Propellants make carbonated drinks expel out of their containers. A propellant creates more pressure to liquid food so that it will come out of their containers and even dispense foam. Common propellants used are Carbon dioxide, Nitrogen, Nitrous oxide, Butane, Isobutane, Propane, Octafluorocyclobutane.
Seasoning is refers to process of adding herbs, spices and condiments to food for enhancing their natural flavor and taste. Cardamom Oil, salt are the commonly used seasoning agents. Seasonings are used while before or after the food is cooked.
Sequestrant improves quality and stability of food by forming chelating complexes with polyvalent metal ions in foods. Bile acid sequestrants lower LDL cholesterol levels in the body. Sequestrants like Sodium Gluconate, Sodium Triphosphate and Calcium Polyphosphate well known examples for this category.
Stabilizers are the substances which maintain color, shape, texture, consistency and stability of food products. Stabilizers can be used for cosmetics, plastics, processed foods. Agar agar, pectin, carrageenan, calcium chloride, alginic acid are the chemicals commonly used as stabilizers in cosmetics, foods, dairy products.
A sweetener is the replica of the normal sugar but varies in low energy and calories. Sweeteners may be natural and synthetic. Synthetic sweeteners are termed as artificial sweeteners. Examples for artificial sweeteners are like aspartame, sucralose, saccharin, neotame.
Thickeners are the modified forms of starch, polysaccharide and vegetable gums. In the preparation of sauces, stews, gravies thickeners are added. Thickening agents used to food preparations for improving their suspension, viscosity without changing their taste.
Acidity regulators also called as ph controlling agents. Acidity regulators alter the acidity and alkalinity of food products. By controlling acidity in foods the growth of bacteria can be avoided from foods. Acidity regulators like lactic acid, citric acid, malic acid, fumaric acid, adipic acid are commonly used for food products.
Antioxidants are the protectors of body cells from free radicals. Antioxidants also prevents from cancers, arthritis, blockage of arteries caused by fatty acid deposition. Food products can be preserved by using antioxidants.
