The Hair Dye You Can Eat
Huito fruit grows across the Caribbean and all the way down to Peru. When ripe, it’s popular as a flavor for preserves and ice cream, but when it’s still green the geniposidic acid it contains makes a tenacious dye when it oxidizes, dyeing anything it touches a rich blue-black. It’s popular for both temporary tattoos and hair color, and it makes a gentle alternative to henna or indigo. So if you’re looking for lush black hair color without chemical dyes, pop by your specialty grocery and see if they have any Huito. If you can’t find the fruit but want to try the dye anyway, you can also buy huito extract (it’s sometimes also called jagua) in many health food stores.
The genipap is native to wet or moist areas of Cuba, Hispaniola, Puerto Rico, the Virgin Islands, and from Guadeloupe to Trinidad; also from southern Mexico to Panama, and from Colombia and Venezuela to Peru, Bolivia and Argentina. Its usefulness to the Indians was reported by several European writers in Brazil in the 16th Century. It is widely cultivated in dooryards as an ornamental tree and for its fruits, but Patiño stated in 1967 that it was no longer as commonly grown in the Cauca Valley of Colombia as it had been in the past. The tree first fruited in the Philippines in 1913 and is occasionally planted there. Otherwise, it is virtually unknown in the Old World. Burkill wrote that it had been tried in the southern part of the Malay Peninsula several times but without success. It is reported in Brazil that there are varieties that bear all year. There is a shrubby form, jenipaporana, or jenipapo-bravo, no more than 10 to 13 ft (3-4 m) high, that grows in swamps along the edges of rivers and lakes in Brazil. The fruit is small and inedible.
Genipap is a small to medium-sized tropical tree. It is 8 to 20 m tall, but specimens of up to 30 meters are also found. The diameter of the trunk is 30 to 80 cm and it has thick, smooth bark. It has a dense crown and the lower branches grow more or less horizontal, with 10 to 35 cm leaves at the ends. In most of Amazon Basin the trees flower in May to September and give fruit between September and April. It takes up to one year for the fruits to mature. In most trees, bees pollinate the flowers. Its fruit is a large, rounded berry, which is 9 to 15 cm long, 7 to 9 cm wide, weighing between 200 and 400 g. It has a thin and leathery covering and a 1 to 2 cm thick layer of soft, yellow-brown pulp. The central cavity contains up to 300 seeds, enclosed in membranes. The fruit is edible only when overripe and soft to the touch, when the flavor (acid to subacid) resembles that of dried apples or quinces.
In Puerto Rico, the fruit is cut up and put in a pitcher of water with sugar added to make a summer drink like lemonade. Sometimes it is allowed to ferment slightly. A bottled concentrate is served with shaved ice by street vendors. In the Philippines, also, the fruit is used to make cool drinks, as well as jelly, sherbet and ice cream. The flesh is sometimes added as a substitute for commercial pectin to aid the jelling of low-pectin fruit juices. Rural Brazilians prepare sweet preserves, sirup, a soft drink, genipapada, wine, and a potent liqueur from the fruits. Analyses made in the Philippines many years ago show the following values for the edible portion (70%) of the fruit: protein, 0.51%; carbohydrates, 11.21%; sugar, 4.30%; ash, 0.20%; malic acid, 0.63%.
The fruit is eaten as a remedy for jaundice in El Salvador. Ingested in quantity, it is said to act as a vermifuge. The fruit juice is given as a diuretic. It is a common practice in Puerto Rico to cut up the fruits, steep them in water until there is a little fermentation, then add flavoring and drink the infusion as a cold remedy. The crushed green fruit and the bark decoction are applied on venereal sores and pharyngitis. The root decoction is a strong purgative. The seeds are crushed and added to water and taken as an emetic in Brazil. When cut, the bark exudes a whitish, sweetish gum which is diluted and used as an eyewash and is claimed to alleviate corneal opacities. The juice expressed from the leaves is commonly given as a febrifuge in Central America. The flower decoction is taken as a tonic and febrifuge.
Pepperidge Farm, which, for seven years, had used artificial colorants in its colored goldfish, switched to natural dyes in July 2010. The colored goldfish are now brightened with Huito juice concentrate, annatto extract, beet juice concentrate, paprika extract, paprika, turmeric extract, and watermelon juice concentrate, instead of blue 2, red 40, red 3 and blue 1.
