Maltodextrin
Whatsapp Order
Maltodextrin is a white, odorless, tasteless polysaccharide produced from partial hydrolysis of starch (typically corn, potato, rice, or wheat starch). It consists of short chains of D-glucose units and is classified by its dextrose equivalent (DE), typically ranging from 3 to 20. Maltodextrin is easily digestible, water-soluble, and has a mildly sweet to nearly neutral flavor depending on its DE value. It is widely used in food, pharmaceutical, and industrial applications as a filler, thickener, bulking agent, and carrier, owing to its excellent functionality and safety.

Fatty Acid
Fatty acids are a group of carboxylic acids consisting of long aliphatic chains, which can be either saturated or unsaturated. They are typically derived from natural fats and oils through hydrolysis or saponification and appear as colorless to pale yellow liquids or solids depending on the chain length and degree of saturation. Fatty acids are fundamental building blocks in biochemistry and industrial chemistry, serving as raw materials in the manufacture of soaps, detergents, lubricants, cosmetics, plastics, and food additives. Their amphiphilic nature—containing both hydrophilic (carboxyl group) and hydrophobic (alkyl chain) components—makes them versatile for various chemical and industrial applications.
