The global chemical industry is increasingly shifting toward sustainable and efficient production processes. One such breakthrough innovation is the enzymatic production of speciality esters, a method that presents significant advantages over traditional thermochemical processes.
Why enzymes?
Enzymes are biological catalysts derived from living organisms, primarily microorganisms such as bacteria and fungi, as well as from plants and animal sources. These naturally occurring proteins accelerate biochemical reactions without being consumed in the process. Industrial enzymes are often produced through fermentation processes using dedicated microorganisms to enhance efficiency and stability.
Enzymes play a crucial role in human biology, aiding in digestion, metabolism, and immune function. For example, digestive enzymes like amylase, protease and lipase help break down carbohydrates, proteins, and fats in the body. They are also used in various medical treatments, including replacement therapies for conditions such as lactose intolerance and pancreatic insufficiency.
Beyond human biology, enzymes are widely used in various industrial applications:
• Food & beverage: Enzymes like pectinase and amylase improve juice clarity, enhance bread texture, and aid in dairy processing
• Pharmaceuticals: Enzymes assist in drug formulation and the production of antibiotics

• Detergents: Proteases and lipases are used in laundry and dishwashing detergents to break down stains and grease at lower temperatures
• Textile & leather processing: Enzymes help soften fabrics, improve dye uptake, and replace harsh chemical treatments in leather production
• Biofuel production: Enzymes convert plant biomass into fermentable sugars, supporting the production of sustainable biofuels
• Speciality chemicals & cosmetics: Used in enzymatic esterification, they facilitate eco-friendly synthesis of speciality esters in cosmetics and personal care products
One of the key advantages of enzymes is their non-hazardous nature. Unlike traditional chemical catalysts, enzymes function under mild conditions, reducing the need for extreme temperatures, high pressure or toxic solvents. They are biodegradable, non-toxic, and generally recognised as safe( GRAS) for food and pharmaceutical applications.
In industrial processes, enzymes help reduce waste and environmental impact, making them a cornerstone of sustainable and green chemistry solutions. With their natural origin, broad application range and environmentally friendly properties, enzymes continue to revolutionise multiple industries while ensuring safety and efficiency in both human and industrial applications.
Understanding speciality esters
Speciality esters are a class of chemical compounds that are widely used in industries such as cosmetics, pharmaceuticals, food and lubricants. They are synthesised via esterification, a reaction between an alcohol and an acid, and can be tailored for specific functional properties such as emollience, viscosity control and solvency. Conventional ester production often relies on thermochemical methods that require high temperatures and catalysts, and produce unwanted by-products.
Enzymatic esterification has long been recognised for its environmental
