"The Science Behind Blueberries' Blue Hue Unveiled by Researchers"

Scientists at the University of Bristol have discovered that the blue color of blueberries comes from tiny structures in their wax coating, not from pigments in the fruit skin. This finding could lead to the development of sustainable and biocompatible colorants and coatings inspired by nature. The study reveals that the blue color of blueberries is provided by a layer of wax with miniature structures that scatter blue and UV light, giving the fruit its distinctive appearance. The researchers aim to explore easier ways of recreating the coating and applying it, potentially leading to the development of sustainable, biocompatible, and even edible UV and blue-reflective paint.
