Desiccated coconut is dried coconut flesh (endosperm) from which nearly all moisture has been removed, typically by drying at low temperatures (around 50–65°C). Desiccation reduces the water activity of the coconut, preventing microbial spoilage and extending shelf life significantly. It is widely used as a food ingredient in confectionery, baking, and cooking.
Desiccated coconut is coconut flesh dried to reduce moisture content to less than 3%.
Drying temperature is typically 50–65°C to preserve fat and flavour.
Desiccation preserves food by reducing water activity (aW) below 0.65.
Most microorganisms cannot grow when water activity falls below 0.7.
Desiccated coconut is approximately 62–65% fat, mostly as saturated fatty acids.
The main fatty acid in coconut is lauric acid, which has antimicrobial properties.
A desiccant (like silica gel) absorbs moisture from the environment.
Sri Lanka and Philippines are the leading producers of desiccated coconut.
Desiccation is the process of thorough drying — removing moisture from a substance to preserve it. The word comes from the Latin 'desiccare' meaning 'to dry up'. In chemistry, desiccation refers to the complete removal of water from a material.
A desiccant is a substance that absorbs moisture from the surroundings. Common desiccants include:
A desiccator is a laboratory apparatus used to store moisture-sensitive chemicals in a dry environment, using a desiccant at the bottom.
The process of making desiccated coconut involves:
The low drying temperature (below 70°C) preserves natural fat content and flavour while removing water.
Drying preserves food by reducing water activity (aW):
Water activity (aW) = P/P₀ (vapour pressure of water in food / vapour pressure of pure water)
Fresh coconut: aW ≈ 0.97 (supports microbial growth) Desiccated coconut: aW < 0.65 (most microorganisms cannot grow below aW 0.7)
Microbial growth inhibition:
Enzyme activity is also slowed at low moisture levels, preventing oxidative rancidity of fats.
Composition of desiccated coconut (per 100g):
Desiccated coconut is available in different forms based on particle size:
Main producing countries: Philippines, Indonesia, Sri Lanka, India Sri Lanka and Philippines are the world's largest exporters of desiccated coconut.
Food industry applications:
Nutritional aspects:
Desiccated coconut is coconut flesh (white endosperm) from which nearly all moisture has been removed by drying at temperatures of 50–65°C. The moisture content is reduced to less than 3%, extending its shelf life and preserving it for use as a food ingredient.
Drying reduces the water activity (aW) of the food. Fresh coconut has aW ≈ 0.97 (supports microbial growth), while desiccated coconut has aW < 0.65. Most bacteria, yeasts, and moulds cannot grow below certain water activity levels, preventing spoilage.
A desiccant is a substance that absorbs moisture from its surroundings to maintain a dry environment. Common desiccants include silica gel, anhydrous CaCl₂, P₂O₅, and concentrated H₂SO₄. A desiccator is a lab device that uses desiccants to store moisture-sensitive chemicals.
Desiccated coconut contains approximately: fat 62–65% (mainly saturated, including lauric acid), carbohydrates ~15%, protein ~6%, dietary fibre ~16%, and moisture less than 3%. It is highly caloric (~596 kcal/100g).
Desiccated coconut is used in confectionery (Bounty bars, macaroons, lamingtons), baking (cakes, biscuits), curries and chutneys, breakfast cereals, ice cream toppings, and health bars. It is a key ingredient in many Indian, Thai, and South Asian recipes.
