Citrus tamurana

Description

Citrus tamurana or hyūganatsu ( 日 向 夏? in Japanese ) is a citrus fruit belonging to the rutáceas family cultivated in Japan . The name comes from Hyūga , old denomination of the prefecture of Miyazaki , in Kyūshū , where it is said that these citrus fruits originated, while natsu ( 夏? ) Means «summer». The hyūganatsu grown outside Kyūshū is occasionally sent under different names like Konatsu. The villagers of Miyazaki tell that a young hyūganatsu tree was suddenly found in a garden of that city, sometime in the 1820s, after which it was widely cultivated throughout the region. It is speculated that it is a mutated yuzu or, perhaps more likely, a hybrid between a grapefruit and a yuzu. The fruit is of medium size and its shape is round or slightly oblong. When it is ripe, it becomes a light yellow color. Its flesh is juicy and sweet with a slightly bitter taste. is usually eaten sliced, sprinkled with sugar and most of the thick bone intact. The fruit oil has high amounts of trans-β-farnesene , l-carvone , and has a higher number of ketones than other citrus fruits.
