Food design studio Bompas & Parr has created luminescent ice cream so cinema-goers can see their snacks in the dark. Bompas & Parr designed the treats for ice cream brand Cornetto to feature the iconic waffle cone and chocolate top but with a glowing yellow filling. To make the ice cream glow, the designers impregnated it with riboflavin – or vitamin B2 – which luminesces under certain wavelengths of light. UV light was shone into the cinema to illuminate the ice cream without impairing the view of the screen. Riboflavin has a bitter taste, but this was masked by the amount of sugar and fat in the mint chocolate-chip ice cream. The team has since taken the idea further and created a series of dessert sauces that are infused with glowing luciferin enzymes from genetically modified bacteria. The enzyme doesn't require UV light to glow and can be seen in food under normal light conditions.
