Chinova Bioworks has a proprietary technology to extract the dietary fiber chitosan from the discarded stems of white button mushrooms. The process involves drying and grinding the fungi, and “purifying out” the fiber with heat and water. The result is a vegan, non-GMO, Kosher, Halal and allergen-free ingredient the company calls Chiber that executives say is at least as effective as synthetic preservatives.###The latest funding round for Chinova underlines the massive potential of natural preservatives. According to research from the International Food Information Council (IFIC), almost two-thirds of consumers say they try to choose foods made from clean ingredients, while roughly half avoid artificial preservatives, sweeteners, colors and flavors at least some of the time.###“The pandemic has accelerated the trend for food safety and health-focused products,” Natasha Dhayagude, co-founder and CEO of Chinova Bioworks, said in a statement. “With this increased consumer awareness and scrutiny, brands are under pressure to keep up and reformulate their products to meet clean-label deman068958016801ds.
