Annatto

 

(Bixa orellana), a tall shrub or small tree of the family Bixaceae. The alternate leaves are cordate-ovate. The large, five-parted flowers are in terminal panicles. The fruit is a polyspermous bivalve capsule. The annatto is native to tropical America. It has been cultivated for a long time in tropical countries of the Old and New Worlds to obtain an orange dye, also known as annatto. The dye is obtained from the fleshy outer covering of the seeds and is used mainly to color butter, margarine, cheese, and similar food products. Indians used the dye as body paint. The annatto is also used as a hedge and as a windbreak.

Current techniques for extracting norbixin are laborious and require solvents that are banned in many countries.
The new approach provides time and cost effectiveness for evaluating norbixin concentrations in whey and whey products.
The researchers found that the limit of detection for both methods was 10 ppb ([micro]g of norbixin per kg of solvent).
The new method detected as little as 30 ppb ([micro]g of norbixin per kg of solids) in liquid whey containing 6.
