The pigment discovered in cabbage will make blue food dye a thing of the past!


Blue color food coloringThe search for a natural alternative to to may have ended with a new blue pigment discovered by scientists in cabbage. The first attempts to use the newly discovered natural blue as a food coloring gave positive results.

Blue color pigments are rarely found in natural resources such as plants and rocks. Most blue products, including drinks, candies, medicine tablets, cosmetics, and clothing, are created using synthetic blue dyes. Synthetic paints are often made from petrochemicals, which is of great concern to human health and environmental impacts.

Natural food coloring with natural blue pigment

Scientists have been searching for natural alternatives to food dyes for decades. A new study by a group of researchers from the University of California published. Pamela Denish and his team announced that they found a blue pigment in red cabbage similar to the artificial food coloring Brilliant Blue FCF or E133.

The natural pigment, a type of anthocyanin molecule, is found only in small amounts in red cabbage. Researchers will process the dominant red anthocyanins found in red cabbage with an enzyme to turn them blue. In this way, a larger amount of blue color will be produced.

Blue food dyes are found in many foods and beverages we consume. With the new discovery, natural blue pigment can replace harmful food dyes.

The team used the new type of blue to make blue ice cream, donut cream, and candy chocolate bars. Made with natural blue dye, these products kept their blue color while being stored under environmental conditions for 30 days.

Although natural, this dye will be tested for safety before being used in foods. One of the authors of the study is from Nagoya University in Japan Kumi Yoshidasaid the new natural blue pigment is unlikely to have adverse health effects. Yoshida, since we have been consuming red cabbage for many years, the it will not be harmful to our health thinks. Because with cabbage we are already consuming this pigment. “Red cabbage anthocyanins have a very long history in our diet,” said Yoshida, stating that the natural alternative is safe. said.

Scientists will reproduce the blue pigments they discovered in red cabbage with special ingredients.

Rebecca Robbins of the Mars Wrigley Global Innovation Center in the United States briefly explained why blue is so rare in nature. Robbins to acquire a blue appearance of complex molecular structures that light must absorb the right wavelengths told.

If the new blue pigment also passes the reliability test, it will be a natural alternative, especially in the food field.
