One of the following is the natural colour used in foods :

  • A.Carmosine
  • B.Tartrazine
  • C.Matanyl Yellow
  • D.Annatto

Answer: D

The natural colour among the options is Annatto.

Annatto is a yellow-orange pigment (bixin and norbixin) extracted from the seed coat of the tropical shrub Bixa orellana. It is widely used to colour butter, cheese, snacks and bakery products.

Carmosine (a red), tartrazine (a lemon yellow) and metanil yellow are synthetic coal-tar dyes. Carmosine and tartrazine are permitted synthetic colours in India, while metanil yellow is a non-permitted dye that is a well-known adulterant of turmeric and sweets.
