The popularity of avocado is down to its rich, creamy texture and mild flavour. The avocado, or Persea Americana, is a fruit that belongs to the family of Lauraceae; a group that also includes members such as cinnamon and laurel. There are dozens of varieties of avocado, ranging in size, colour and texture. All are native to tropical climates and when harvested, the flesh softens to a buttery texture that has become extremely popular in everything from dips to desserts.
The fruit of domestic varieties has buttery flesh when ripe. Depending on the variety, avocados have green, brown, purplish, or black skin when ripe, and maybe pear-shaped, egg-shaped, or spherical. Commercially, the fruits are picked while immature and ripened after harvesting.
Raw avocado flesh is 73% water, 15% fat, 9% carbohydrates, and 2% protein (table). In a 100 gram reference amount, avocado supplies 160 calories, and is a rich source (20% or more of the Daily Value, DV) of several B vitamins (such as 28% DV in pantothenic acid) and vitamin K (20% DV), with moderate contents (10-19% DV) of vitamin C, vitamin E, and potassium. Avocados also contain phytosterols and carotenoids, such as lutein and zeaxanthin.
