Curcumin is a diketone
compound extracted from the rhizomes of some plants in
Zingiberaceae and Araceae. Among them, turmeric
contains about 3% to 6% curcumin, which is a rare
pigment with a diketone structure in the plant kingdom.
Curcumin is an orange-yellow crystalline powder with a
slightly bitter taste and is insoluble in water.
Curcumin has been widely used in the food industry as a
common natural pigment for a long time. It is mainly
used for the dyeing of canned food, sausage products,
and stewed sauce products. The amount of use depends on
normal production needs. The product form of functional
food with curcumin as the main ingredient can be
general food, or some non-food form, such as capsules,
pills or tablets. For general food forms, some yellow
pigment foods can be considered, such as pastries,
sweets, beverages, etc.
