Food colorings, like Red 40 and Yellow 5, often include synthetic, petroleum or animal-derived products, but in recent years, the $2.6 billion food colors market has trended toward using natural ingredients as more consumers want more clean labels for the foods they eat.

Startups have come in with their approaches to healthier food colors, ingredients and flavorings. For example, Vanilla Vida, Spero Renewables and Pigmentum are working on vanilla. Motif FoodWorks is developing a beef flavor substitute, while Brightseed and Equinom are creating compounds and proteins to make ingredients for healthier foods.
