Sugar is scientifically referred to as sucrose. The chemical formula of sugar is

Physical Properties of Sugar

Appearance: It is a white crystalline solid.

Solubility: Freely soluble in water; 100 g of sugar can dissolve in about 200 mL of water at room temperature.

Density: About 1.587 g/cm³ in its crystalline form.

Melting Point: About 186°C (367°F). Sugar does not have a true melting point as it decomposes upon heating.

Boiling point: Decomposes without boiling, hence there is no boiling point as such in standard conditions.

Taste: Sweet and hence very useful as a sweetener in foods and beverages

Odor: Odorless.

Chemical properties of Sugar

Hydrolysis:

Sucrose hydrolysis is the action of an acid or enzyme into glucose and fructose.

Fermentation:

From yeast action, an enzyme, or an acid, hydrolyzes into an end product, ethanol, and carbon dioxide.

Oxidation:

Under certain conditions, sucrose is oxidized to produce, among other things, carboxylic acids.

Reactions with Acids:

Dehydration properties of the sucrose cause a reaction with concentrated sulfuric acid, producing carbon, water, and other products.

Application of Sugar

Food and Beverage Industry:

Sweetener: Sugar is used as the main sweetener in various food products; these include cakes, sweets, carbonated drinks, and sweets. Sugar adds flavor and helps in the textures and colors of food.

Preservative: Sugar acts as a preservative because it prevents the growth of microbes by its hygroscopic nature, drawing water away from the microorganism.

Fermentation: Used in brewing and wine industries as a fermentable sugar to produce alcohol and carbon dioxide.

Pharmaceuticals:

Excipients: Used as a filler and binder for tablets and capsules, it stabilizes the medication and helps right dosing.

Syrups: It sweetens the medicinal syrups for palatability purposes, especially in children.

Cosmetics and Personal Care:

Exfoliant: Utilized in scrubs and exfoliating products due to the granular nature of the product, which will help remove dead skin cells.

Moisturizer: Utilized in a variety of cosmetic preparations to retain water in the skin.

Industrial Uses:

Sugars Refining: It finds its application in various refining processes, where impurities are removed to produce high-purity sugar for consumption and further processing. Biochemical Processes: Feeds as a carbon source in the production of bioethanol and other biochemicals through fermentation processes.

Agriculture:

Soil Conditioning: Sometimes utilized as a soil conditioner to enhance microbial activity and improve soil fertility.

Packaging:

Edible Films: Sugar is applied in the manufacturing of edible films and food coatings that may protect a product and extend its shelf life.

Laboratory Research:

Reagent: Used as a general reagent in several biochemical and chemical tests, such as in studies on enzyme activities and carbohydrate metabolisms.

Sugared Foods: Included in specialty foods such as jams, jellies, and preserves for body and preservation.

Conclusion

Sugar (sucrose) is a versatile compound that usually finds application in food and beverages as a sweetener, in pharmaceutical applications as an excipient or binder, and sometimes in personal care products. Its applications also extend to industrial processes and specialty products; therefore, it finds relevance both in everyday life and in a variety of commercial and scientific applications.
