|Hassaku, whole and sectioned|
Cultivation and uses
The Japanese eat the 'Hassaku' as an orange, but it can be eaten with a grapefruit spoon to avoid the bitterness of the residual albedo. It is much more tart than an orange, but it does not lack sweetness entirely. When bitten into, juice bursts into the mouth from a slice of this fruit, considered very pleasant.
The fruit is mostly eaten raw, because, when cooked, it becomes more bitter. Currently, the idea of using ion-exchange resin is being suggested as a way to remove the bitterness, and so make it possible to commercialize the juice. Nutritionally, the fruit is a good source of vitamin C, folic acid, potassium and fiber.
Hassa-kun is a local mascot character which represents Inno-shima in Hiroshima prefecture to enhance image and promote tourism.
