The blue strawberry may have a familiar form like the regular one, but its unique and eye-catching color sets it apart. Many individuals do express worry about the blue hue, assuming it has been sprayed with harmful chemicals or dyed artificially.
Actually, these strawberries have undergone genetic modification by incorporating a unique gene called the Anti-Freeze Protein (AFP) gene from Arctic flounder fish. As a result, the appearance of these strawberries has been changed.
The Arctic flounder fish has a gene that enables it to create an antifreeze protein to survive in chilly water. By injecting this gene into the sky-blue strawberry variety, the fruit can endure longer periods without getting mushy or spoilt in typical weather conditions unlike regular strawberries.
Apart from their distinct hue, sky-blue strawberries also possess a prolonged storage capacity as compared to their red or yellow counterparts during their transportation and preservation.

Even when kept in cold storage like fridges or coolers, these distinctively blue-colored strawberries manage to hold on to their delicious flavor.
Similar to other varieties of strawberries, they are cultivated using seeds. Nevertheless, the accessibility of this one-of-a-kind fruit and its seeds remains restricted in most markets.
Experts are still researching and enhancing the development of sky-blue strawberries, with the aim of eventually making them available for purchase to the general public.
