Konatsu Oranges are juicy, sweet citrus fruits known for being high in vitamin C.
Beneficial nutrients and plant compounds orange
It’s perhaps less well known that orange peels are also rich in several nutrients, including fiber, vitamin C, and plant compounds like polyphenols.
In fact, just 1 tablespoon (6 grams) of orange peel provides 14% of the Daily Value (DV) of vitamin C — nearly 3 times more than the inner fruit. The same serving also packs about 4 times more fiber (1Trusted Source, 2Trusted Source).
Orange peel also contains good amounts of provitamin A, folate, riboflavin, thiamine, vitamin B6, and calcium (1Trusted Source).
Plus, it’s rich in plant compounds called polyphenols, which may help prevent and manage many chronic conditions, such as type 2 diabetes, obesity, and Alzheimer’s (7Trusted Source).
Studies show that diets high in vitamin C and fiber benefit heart and digestive health and may protect against certain types of cancer (3Trusted Source, 4Trusted Source, 5Trusted Source, 6Trusted Source).
One test-tube study found that the total polyphenol content and activity in orange peels were significantly higher than in the actual fruit (8Trusted Source, 9).
Specifically, orange peels are a good source of the polyphenols hesperidin and poly methoxy flavones (PMFs), both of which are being studied for their potential anticancer effects (9, 10, 11Trusted Source).
Geography/History Konatsu orangeKonatsu citrus is native to the Miyazaki Prefecture in Kyushu, Japan, and was first discovered as a natural mutation in 1820 in Mr. Yasutaro Magata’s home garden. Although the first Konatsu was considered to be too acidic, over time, growers developed a sweeter version that is cultivated and sold in the markets today. Konatsu citrus is primarily localized to regions in Japan and can be found at local markets and specialty grocers.

Konatsu citrus, botanically classified as Citrus Tamura, is a unique hybrid that grows on evergreen trees and belongs to the Rutaceae or citrus family. Also known as Hyuganatsu, New Summer oranges, and Tosakonatsu, Konatsu citrus is believed to be a naturally occurring hybrid of yuzu and pomelo and is grown in Japan. While piths are typically discarded from citrus because of their bitter nature, Konatsu piths are sweet and are encouraged to be consumed to balance out the sour nature of the flesh.
