Citric acid

Citric acid is used as a flavor enhancer in beverages. It is used in soft drinks, teas, juices, and other beverages to create a slightly tart, refreshing flavor and balance sweetness.

The acidic pH of citric acid also makes it useful as a preservative. Since many bacteria are unable to grow in an acidic environment, citric acid is often added to jams, jellies, candy, canned foods, and even meat products as a preservative.

Because citric acid can be made in a powder form, it can be used in dry foods when a sour flavor is desired. Citric acid is sometimes used to create an acidic environment and facilitate the ripening process when making cheese, particularly mozzarella.

A weak tribasic acid, citric acid is organic in composition. A vital part of metabolism in most living organisms, citric acid is widely prevalent in nature.

Citric acid is mass produced owing to its popular demand and vast applications. Some of the conventional uses of this acid are acidifiers, chelating agents and flavouring agents.

Citric acid prevails in two major forms, the anhydrous or water-free form and the monohydrate form. The anhydrous form is crystallized by application of hot water, whereas the monohydrate form is extracted by using cold water crystallization. Citric acid has numerous applications in the food industry and cosmetic industry.

Areas of application:

  • Food additives, soft drinks, beverages, emulsifying agents.

Sodium bicarbonate

Product Details:
  • Type: Chemical Grade
  • Form: Powder

Baking soda is a leavening agent used to make dough rise. The alkalizing effect of baking soda will soften the fiber in beans and start to dissolve the protein, making the beans easier to digest after cooking.

Sodium bicarbonate makes soda fizzy by producing carbon dioxide gas when mixed with an acid such as phosphoric acid or carbonic acid found in many colas.

Sodium Bicarbonate is an ingredient used in the manufacturing of food colorants. Because of its anti-caking and stabilizing properties, it's used in the base of many food color gels. Usually this is used in such minute amounts that it has very little effect on your blood sodium levels.

Sodium and bicarbonate ions combine to form Sodium bicarbonate. It is a salt in white crystalline solid or powder form. In its natural form, it is termed nahcolite. Commonly referred to as baking soda, this salt is attributed with an alkaline taste much like the washing soda (Sodium carbonate).

Baking soda is one among the many conventional names attached to this salt. Some others are bread soda, aerated salt, cooking soda and bicarbonate of soda.

Baking soda, apparent from its name, is fundamentally used in baking. The ions in this salt react with components of baking mixtures resulting in production of carbon-di-oxide, which causes the mix to rise and form characteristic textures.

Soya Lecithin

Lecithins are oily substances that occur naturally in plants and animals.

Some people use lecithin as a supplement because of its high choline content. Choline is a micronutrient that is good for a healthy heart and for brain development. But that’s not the reason it is used as an additive in foods. Soy lecithin possesses emulsification properties. It is also used in bakery items to keep the dough from sticking and to improve its ability to rise.

A yellowish-brown fatty acid found primarily in plant tissues is labelled as ‘lecithin’. Amongst loving water and fats and freely binding with both, lecithins have a number of desirable properties. Owing to these properties, lecithins are used to smooth food textures, improve food dissolution properties (emulsifiers), homogenize a mix of liquids and repel sticky materials.

Soy lecithins are constituents of numerous candy bars, used to bind substances together to ensure they don’t fall apart. Bakery dough, cocoa, cocoa butter and other components of food products are bound by soy lecithin.

Some other unconventional products that use soy lecithin are teabags, inhalers, cough drops and medicinal preparations.

Although the main reason for the use of sugar is its sweet taste, sugar has many other functions in food technology. Sugar in foods acts as a sweetener, preservative, texture modifier, fermentation substrate, flavouring and colouring agent, bulking agent.

Sugar is short chain, soluble carbohydrates, widely used to sweeten food products. Sugars exist is various forms, largely categorised as simple and complex sugars. Simple sugars, termed as ‘monosaccharides’, include glucose, fructose sand galactose. These sugars are made up of repetitive units of similar building blocks. Complex sugars or ‘disaccharides’, such as sucrose, maltose and lactose are made of a combination of smaller dissimilar units of simple sugars. Longer chains of sugars are termed as ‘oligosaccharides’.

Although sugars are found in all plants, only select plants like sugarcane and beet have sufficient concentrations of sugar which make it economical to extract the product.


Areas of application:

  • Food industry – baked goods, confectionaries, jams, marmalades, breweries.
