How to select & store
Picking a ripe one
Choose fully ripe, deep red-orange fruit that is soft and heavy; unripe green or orange fruit lacks the vivid, nutrient-dense red arils. It is spiky, so handle with care.
Storing it
Ripe gac is used quickly; the red aril paste is scraped from the seeds and often frozen. It is increasingly sold abroad as frozen pulp, powder, and oil-based supplements.

- Called the "fruit from heaven" in Vietnamese for its color and reputed benefits
Gac is a fruit grown for what it contains rather than how it tastes. A spiky crimson gourd from Southeast Asia, its flavor is mild — closer to squash than sweet fruit — but the red membranes coating its seeds are a nutritional marvel: among the richest natural sources of lycopene and beta-carotene ever measured, carried in an oil that helps the body absorb them.
The color of celebration
In Vietnam, gac’s brilliant red is auspicious, and its signature use is xoi gac — festive sticky rice tinted and enriched with the aril, served at weddings and Lunar New Year. There, the fruit is a natural dye and a nutrient booster rolled into one, valued for making a celebratory dish both beautiful and nourishing.
From rice pot to supplement bottle
That carotenoid density turned gac into a modern “superfruit,” exported as frozen pulp, powder, and oil capsules marketed for eye and skin health — echoing the traditional Vietnamese and Chinese uses for eyesight and vitality. Like tomato and watermelon, its lycopene is best absorbed with a little fat, which the oily aril conveniently provides.
