Often called the fruit of heaven, it is particularly popular in Vietnam and other parts of Southeast Asia, where it is traditionally used in cooking and special festive dishes.

What Is Gac Fruit?

Gac fruit, scientifically known as Momordica cochinchinensis, is a tropical fruit belonging to the cucumber and melon family, Cucurbitaceae. It grows on a climbing vine and is native to Southeast Asia, particularly Vietnam.

The fruit has a round or oval shape with a thick, spiky orange-red outer skin. When opened, it contains a yellowish pulp and large seeds covered with a bright red, oily membrane called the aril.

The red aril is the most nutritionally interesting part of gac fruit because it contains high concentrations of lycopene and beta-carotene.

Gac fruit has a mild, slightly sweet flavour and is commonly cooked with sticky rice in Vietnam to prepare a traditional dish called xoi gac. It is also used in juices, purees, powders, and nutritional food products.

Unlike many familiar fruits, gac is not usually eaten like an apple or orange. Its pulp and red aril are generally separated from the seeds and prepared before consumption.

It contains naturally occurring lycopene and beta-carotene.
Its red aril is particularly rich in carotenoid pigments.
It provides plant compounds with antioxidant activity.
