To be hot on someone's heels - Tradução em português
Meanwhile, Indiana-based MonoSol is hot on Dr Edward's heels. Its water-soluble casings are already widely used to make squidgy pods of washing detergent. The company has been developing tasty edible films that are strong enough to act as packaging until they come into contact with water and dissolve. Products in the pipeline include individual servings of hot chocolate and other drinks that you slip straight into cups, and single servings of flavoured porridge. The company currently is punting the product to major food brands and it could be on the shelves in a year or two.
