Description

technical field

[0001] The invention relates to carminic acid, in particular to a water-soluble carminic acid lake. Background technique

[0002] Carminic acid is an anthraquinone natural pigment, which mainly exists in the female cochineal (Dactylopius coccus costa) (also known as "Coccus cacti L."). ) and other cacti, which are commonly grown in desert regions such as Mexico and Central and South America. Depending on the pH value, the color of carminic acid colorants can range from orange to red to purple. Generally, carminic acid pigments and their derivatives are collectively referred to as cochineal. This pigment is widely used in the fields of food and medicine middle.

[0003] The pigments in cochineal dried body are usually extracted by water or alcohol. However, in the process of extracting carminic acid, proteins and other substances soluble in water or alcohol in insects are also taken out, and thus exist in the extraction liquid. According to related reports...
