History

The annatto tree ''B. orellana'' is believed to originate in tropical regions from Mexico to Brazil. It was probably not initially used as a food additive, but for other purposes such as ritual and decorative body painting (still an important tradition in many Brazilian native tribes, such as the Wari'), sunscreen, and insect repellent, and for medical purposes. It was used for Mexican manuscript painting in the 16th century. Annatto has been traditionally used as both a coloring and flavoring agent in various cuisines from

Industrial food coloring

Annatto is commonly used to impart a yellow or orange color to many industrialized and semi-industrialized foods, including cheese, ice cream, bakery products, desserts, fruit fillings, yogurt, butter, oils, margarines, processed cheese, and fat-based products. In the United States, annatto extract is listed as a color additive "exempt from certification" and is informally considered to be a natural coloring. Foods colored with annatto may declare the coloring in the statement of ingredients as "colored with annatto" or "annatto color." In the European Union, it is identified by the

Cheese

In cheese, the yellow and orange hues naturally vary throughout the year as the cow's feed changed: in the summer, with fresh grass and its natural carotene content, the milk produced would have a natural orange tint, as would the cheese made from it, while at other times of the year, the tint would be greatly reduced. As the pigment is carried in the cream, skimming the milk, which some farmers did to make butter or to sell it separately, the lesser-quality cheese from such milk would be white. To fool the consumer, the cheesemakers introduced colorants to imitate the more intense colors of the finer summer cheese. Initially these colors came from saffron, marigold, and carrot juice, but later annatto began being used. In the 17th century, the Dutch, who had established colonies in Guyana, traded in food, particularly an orange-red natural colorant, annatto, with the indigenous communities. Zeeland traders under the authority of the West India Company bought annatto from the inhabitants of the coastal regions of Guyana and Suriname and sold it in the Netherlands as ''verw'' ('paint'). One contemporaneous description comes from Adriaen van Berkel, in a book published in 1695, though he does not mention whether it was used in cheese. The earliest known documentation of annatto's use in cheese is in a 1743 Dutch volume ''Huishoudelyk Woordboek'' (''Household Word Book''), according to American scientist Paul Kindstedt of the University of Vermont. Other historical documents from the period confirm that using annatto (then called "orleaan" or "orleans") to color cheese was being done by the mid-18th century. England is another country that has used annatto to color their cheeses; colorants had been added to
