Natural Food Colors Rise as Synthetic Dyes Fade

Natural Food Colors Rise as Synthetic Dyes Fade \ Newslooks \ Washington DC \ Mary Sidiqi \ Evening Edition \ As U.S. health officials push to phase out artificial food dyes, companies like Sensient Technologies are racing to develop natural alternatives. Switching to plant-based colors is complex, costly, and time-consuming. Major food brands are preparing to reformulate products ahead of 2026 deadlines.

Deep Look

A monumental shift is underway in the U.S. food industry as health authorities and consumers demand the elimination of petroleum-based artificial dyes from everyday products. Leading the charge are scientists like Abby Tampow, working at Sensient Technologies Corp., one of the world’s top dye manufacturers. Her mission: to recreate the vivid synthetic reds seen in bottled raspberry vinaigrettes, using only natural ingredients like carrot juice and beta-carotene.

Tampow’s meticulous work exemplifies the wider scramble taking place across the U.S. food sector. Driven by federal initiatives, health advocates, and consumer pressure, major food manufacturers are now racing to replace synthetic dyes in cereals, sports drinks, salad dressings, and more. The urgency increased after U.S. Health Secretary Robert F. Kennedy Jr. declared artificial dyes “poisonous compounds” last week, urging companies to voluntarily phase them out by 2026.

The Food and Drug Administration currently permits about three dozen color additives, including eight synthetic dyes. However, growing evidence linking artificial colors to potential health risks, especially in children, has ignited a wave of reform. Studies suggest artificial dyes may exacerbate hyperactivity and attention disorders, fueling parental and public concern. Meanwhile, state bans and new federal scrutiny, like the prohibition of Red 3 due to cancer risk in animals, have put additional pressure on the industry.

Despite public enthusiasm, the transition to natural dyes won’t happen overnight. Food scientists warn that reformulating products is a long and complex process. Monica Giusti, a food color expert at Ohio State University, points out that global supplies of natural pigments are nowhere near sufficient to replace synthetic dyes across the entire market. “We are not really ready,” Giusti said, adding that converting a single product can take six months to a year, while scaling up the supply of raw materials might require several more years.

Paul Manning, CEO of Sensient Technologies, echoed those concerns. Unlike synthetic colors produced in industrial quantities, natural dyes require agricultural input: fields of beets, carrots, spirulina, and other crops must be grown, harvested, and processed. “It’s not like there’s 150 million pounds of beet juice sitting around,” Manning noted. “You need tens of millions of pounds grown and extracted.”

Sensient collaborates with farmers globally to source raw concentrates, which are then processed into liquids, powders, or granules tailored for commercial food production. However, natural colors present major technical challenges. They are less consistent, more sensitive to heat, acidity, and light, and harder to maintain during production. Blue pigments, in particular, are exceptionally difficult to replicate naturally.

Moreover, cost is a significant barrier. Producing natural dyes is roughly 10 times more expensive than creating synthetic counterparts. Manufacturers must find ways to deliver the vividness and stability of artificial dyes while adhering to new natural standards — a scientific and logistical hurdle that cannot be underestimated.

In some cases, exotic sources offer solutions. For example, Sensient officials explained that achieving the vibrant “Barbie pink” color, once derived from Red 3, might now require pigments from cochineal insects — tiny bugs living on prickly pear cactuses in Peru. About 70,000 cochineal insects are needed to create just one kilogram of dye.

Despite these complexities, the movement away from artificial dyes is gaining momentum. Approximately one in five U.S. food products contains added colors, many with multiple dyes, according to industry estimates. Although the FDA maintains that certified colors are safe when used within guidelines, critics argue that artificial colors are largely cosmetic, marking foods as ultra-processed and contributing to broader health concerns like obesity, diabetes, and heart disease.

Food policy experts, including Marion Nestle, argue that artificial colors offer no nutritional or safety benefit. “They are strictly cosmetic, have no health or safety purpose, and may be harmful to some children,” she said, applauding efforts to remove them.

Still, the path to natural coloring is not without risk. Companies have previously faced consumer backlash when changing formulations. One cautionary tale is General Mills’ attempt in 2016 to switch Trix cereal to natural dyes using turmeric, strawberries, and radishes. Although the intention was to align with consumer demands, the resulting muted colors disappointed fans, prompting General Mills to reintroduce artificial dyes the following year.

Consumer expectation and brand loyalty present significant hurdles when making such visible changes to familiar products. As Monica Giusti noted, “When it’s a product you already love, and it changes slightly, it may not really be the same experience.”

Despite no formal legal requirement yet, Kennedy claims that there is an “understanding” between U.S. officials and major food companies about voluntarily eliminating synthetic dyes. Companies like PepsiCo and General Mills have already announced plans to accelerate the transition. PepsiCo CEO Ramon Laguarta noted that most of the company’s products are now free of artificial colors, with remaining brands like Lay’s and Tostitos on track to complete the shift by year’s end.

Similarly, WK Kellogg Co. has pledged to remove synthetic colors from cereals used in school lunch programs by next January and to avoid launching any new products containing them.

At Sensient, the pressure is mounting but the opportunity is equally vast. Manning emphasized that now, with a 2026 target in place, companies must act swiftly. “Now that there’s a date, there’s a timeline,” he said. “It certainly requires action.”

The natural color revolution is no longer a question of “if” but “how fast” — and the race to paint America’s food supply in plant-based pigments has officially begun.
