Will root crops develop into a source of natural pigment?

Researchers recently said that purple sweet potatoes and black carrots have replaced synthetic and animal-sourced pigments and quietly become the source of a new generation of natural pigments.At the American Chemical Society
(ACS)

National Conference and Expo in the United States, researchers said the global food and beverage industry is looking for sustainable sources of natural food
coloring to meet the needs of consumers and manufacturers;Dr
Stephen Talcott
, from Texas A.M., explains: "The natural pigment industry, which serves the food and beverage industry, is becoming increasingly profitable as companies in the U.S. and internationally begin to use sustainable and affordable crops instead of synthetic erythromycin or red pigment extracted from insects. Headded: "In addition to adding visual appeal to food and beverages, natural pigments can also add natural plant antioxidant compounds, which may also be beneficial to health."a major change in recent years, he says, has been the emergence of root crops such as black carrots and purple sweet potato

(PSPs)
, which are grown specifically for natural pigment production.The potential value of sweet potatoesU.S. researchers point out that anthotin extracted from purple sweet potatoes (
PSP
has proven to be the best food and beverage colorant, such as in fruit juice drinks, vitamin water, ice cream and yogurt.Talcott
points out that, in fact, natural pigments extracted from
PSP
are stable, not easy to break down, and have superior color properties;same,
PSP
antholine is superior to traditional synthetic red food coloring and extracts sebum red pigment from carp, he said.he also points out that
PSP
also has the advantages of sustainability and easy production. The aphid feed is made in some cacti in South America and Mexico and requires about
2,500
bugs to produce an ounce of aphid extract.extraction ,
Talcott
that
pigment
purple sweet potatoes can be very difficult to extract. The team noted that the starchy composition of
PSP
and the unusually high level of polyphenol oxidase, which are not clearly found in oranges, "cause additional treatment challenges."" during pigment extraction, these natural enzymes are activated and oxidized with chlorogenic acid, which causes a compound oxidation reaction that destroys anthotin. " Talcott
that
has
new
in the
extraction of pigments from PSP data.noted that these new and more efficient processes could encourage the development of the domestic natural food coloring industry, as well as agricultural development dedicated to the growing manufacture of food and beverage colors.by-products of these processes, including starch and fiber, can be used as raw materials for animal feed, biofuel production or for various other food applications, he added.addition, this by-product can also be used as compost or soil improver to produce more
PSP
or other crops,
Talcott
said.
