out of the U.S. food supply, the shift may well start at Abby Tampow’s laboratory desk.On an April afternoon, the scientist hovered over tiny dishes of red dye, each a slightly different ruby hue. Her task? To match the synthetic shade used for years in a commercial bottled raspberry vinaigrette — but by using only natural ingredients.“With this red, it needs a little more orange,” Tampow said, mixing a slurry of purplish black carrot juice with a bit of beta-carotene, an orange-red color made from algae.

Tampow is part of the team at Sensient Technologies Corp., one of the world’s largest dyemakers, that is rushing to help the salad dressing manufacturer — along with thousands of other American businesses — meet demands to overhaul colors used to brighten products from cereals to sports drinks.“Most of our customers have decided that this is finally the time when they’re going to make that switch to a natural color,” said Dave Gebhardt, Sensient’s senior technical director.

In the collaborative, hospitals get toolkits full of materials such as care guidelines in multiple formats, articles on best practices and slide sets that spell out what to do in medical emergencies, how to set up medical teams and what supplies to keep on the unit. The collaborative also tackles issues such as improving obstetric care by integrating midwives and doulas – whose services are covered by the state’s Medicaid program.At first, some doctors resisted the effort, figuring they knew best, Williams said, but there’s much less pushback now that the collaborative has proven its value.
