Despite Japan’s hot summer, some consumers are finding that their popsicles are not melting easily. A kind of popsicle that can withstand hot weather has become very popular. Its secret ingredient is polyphenol– a liquid extracted from strawberries. Polyphenol makes it difficult for water and oil to separate, so the popsicles maintain their shape in high temperature. In a store in Tokyo’s Harajuku, one such treat costs around 5 dollars. Over 300 such popsicles are sold every day.
