Miyagawa mandarins are an excellent source of vitamins A and C and contain dietary fiber, potassium, copper, calcium, and magnesium. They are also valuable sources of flavonoid antioxidants such as naringenin, naringin, and hesperetin.
Miyagawa mandarins are medium to large in size, averaging 6-7 centimeters in diameter, and are round to oblate with a slightly lopsided shape. The thin rind ranges in color from green to orange, depending on the climate it is grown in and is easy-to-peel, smooth, shiny, and covered in small oil glands.
