Achiote is a tropical evergreen shrub, native to Central and South America, known for its seeds used in food coloring.
Brief History and Description
An evergreen shrub with a normal height of 6 to 10 meters, achiote, also known as annatto or lipstick tree, is native to the tropics of Central and South America. The fruits, which are reddish and have a surface coated in short, stiff hairs, are shaped like hearts and have lovely pink blooms. The orange-red pigment extracted from the fruit's seeds is used as commercial or food coloring.
Culinary Usage and Nutritional Properties
The seeds of achiote are rich in carotenoids and bixin, a powerful antioxidant. It is also rich in calcium, fiber, and vitamin C.
This species' leaves, fruits, and seeds are said to be edible. Achiote seeds contain a pigment that can be used to color butter, margarine, and cheese, including Cheddar, Edam, and Munster. It can be mixed into Mexican rice, used as a culinary coloring, or used to flavor sweets, chocolates, and other pastries. Its seeds are used to add taste and color to marinades and sauces. The seeds are also used to season seafood, slow-cooked meats, soups, and stews. The leaves are also used as seasoning.
Economic and Environmental aspects
In addition to being evergreen and good at absorbing carbon, the Achiote tree drops many leaves, adding organic matter to the soil. Simultaneously, even a row of trees produces an excellent windbreak. Birds eat the fruit, and farmers use it to shade crops.
The most utilised component of this plant, Achiote seeds, are now one of the world's most frequently used natural food colorings. Around 14,500 tons (dry weight) of acuminate seeds are produced annually worldwide. One-third of the material is allocated for dye production, while the remaining two-thirds are utilised to produce dried seeds. Today, achiote extract is a natural hue mostly used in the food, cosmetic, and pharmaceutical industries because it doesn't alter the flavor and is essentially non-toxic. This plant is of enormous economic and commercial significance throughout the world.
Annual Yield
A 3-year-old plant, on average, may yield about 0.5 to 1 kg of seeds per year.
