54 Lemon Citrus limon The lemon is a small evergreen tree native to Asia, and the tree's ellipsoidal yellow fruit. The fruit is used for culinary and non-culinary purposes throughout the world, primarily for its juice, though the pulp and rind are also used in cooking and baking. The juice of the lemon is about 5% to 6% citric acid, which gives lemons a sour taste. The distinctive sour taste of lemon juice makes it a key ingredient in drinks and foods such as lemonade. 28885 Lemon 54.jpg image/jpeg 286671 2012-04-20T09:34:12Z 57 Fruits Citrus Type 1 2011-02-09T00:37:17Z 2019-05-14T18:04:15Z false specific 2708 true FOOD00054
