Macapuno or kopyor coconut. As seen in the picture, the coconut has thicker crumpled, abnormal, white flesh.

A macapuno (Filipino), kopyor (Indonesian) or kathi (Thai: กะทิ) is a coconut sport or naturally occurring mutant which has an abnormal development of the endosperm. The result of this abnormal development is a soft, jelly-like flesh.[1]

Normal coconut flesh mostly consists of galactomannan as a source of energy. In the development process, this substrate is degraded into two sub-components, galactose and mannose. In the mutant the enzyme for degrading this substrate, α-D-galactosidase, is not active. Hence, the endosperm fails to nourish the embryo, resulting in a collapsed embryo. Besides this enzyme, a couple of other enzymes are also suspected of being involved in the development of this trait: sucrose synthase and stearoyl acyl carrier protein desaturase.

Kopyor coconuts have a higher sucrose proportion (92% of total sugar) and contain more total amino acids compared with young mature coconuts. The lipid content in the flesh is also lower compared to young mature coconut flesh. In addition to the higher content of citric and malic acids, all these properties may contribute to the taste of kopyor flesh.[2]

Culinary uses

Es kelapa kopyor is an Indonesian dessert drink. Together with es cendol and es teler, these drinks are considered as one of Indonesian culinary heritage.

In Indonesian cuisine, kopyor coconut or kelapa kopyor is considered a delicacy. Es kelapa kopyor is a dessert drink which is usually made using this coconut.

In Filipino cuisine, macapuno is widely used and is popular for its sweet coconut flavor. It is typically cooked in syrup as a minatamis (candied fruit) and may be eaten as dessert or used as an ingredient in other desserts such as halo-halo and ube macapuno.
