America's red gold: multiple lineages of cultivated cochineal in Mexico

Cultivated cochineal (Dactylopius coccus) produces carminic acid, a valuable red dye used to color textiles, cosmetics, and food. Extant native D. coccus is largely restricted to two populations in the Mexican and the Andean highlands, although the insect's ultimate center of domestication remains unclear. Moreover, due to Mexican D. coccus cultivation's near demise during the 19th century, the...

New risks from ancient food dyes: cochineal red allergy.

This study reports an unusual case of IgE-mediated hypersensitivity to Cochineal red or Carmine red, a coloring agent of natural origin. Although the risk of anaphylactic reactions is well known, since the nineties the use of this additive seems to be nowadays on the rise. The problem of labeling of additives used in handmade food products is highlighted.

Estimates of nuclear DNA content in red algal lineages

BACKGROUND AND AIMS The red algae are an evolutionarily ancient group of predominantly marine organisms with an estimated 6000 species. Consensus higher-level molecular phylogenies support a basal split between the unicellular Cyanidiophytina and morphologically diverse Rhodophytina, the later subphylum containing most red algal species. The Rhodophytina is divided into six classes, of which fi...
