Coconut milk is an opaque, milky-white liquid extracted from the grated pulp of mature coconuts. The opacity and rich taste of coconut milk are due to its high oil content, most of which is saturated fat. Coconut milk is a traditional food ingredient used in Southeast Asia, Oceania, South Asia, and East Africa. It is also used for cooking in the Caribbean, tropical Latin America, and West Africa, where coconuts were introduced during the colonial era.
Coconut milk is differentiated into subtypes based on fat content. They can be generalized into coconut cream (or thick coconut milk) with the highest amount of fat; coconut milk (or thin coconut milk) with a maximum of around 20% fat; and coconut skim milk with negligible amounts of fat. This terminology is not always followed in commercial coconut milk sold in Western countries.
Coconut milk can also be used to produce milk substitutes (differentiated as "coconut milk beverages"). These products are not the same as regular coconut milk products which are meant for cooking, not drinking. A sweetened, processed, coconut milk product from Puerto Rico is also known as cream of coconut. It is used in many desserts and beverages like the piña colada, though it should not be confused with coconut cream.
In a 100 milliliter (ml) portion, coconut milk contains 230 kilocalories and is 68% water, 24% total fat, 6% carbohydrates, and 2% protein (see table). The fat composition includes 21 grams of saturated fat, half of which is lauric acid.
Coconut milk is a rich source (20% or more of the Daily Value, DV) of manganese (44% DV per 100 g) and an adequate source (10–19% DV per 100 g) of phosphorus, iron, and magnesium, with no other nutrients in significant content (see table).
Coconut milk is a relatively stable oil-in-water emulsion with proteins that act as emulsifiers and thickening agents. It is opaque and milky white in color and ranges in consistency from watery to creamy. Based on fat content, coconut milk is divided into different subtypes generally simplified into "coconut cream", "coconut milk", and "coconut skim milk", from highest to lowest respectively.
