Experts from the Korean Rural Development Administration confirm that the albedo layer of oranges and tangerines offers numerous benefits and should not be discarded.
This white layer is rich in pectin, a soluble fiber that protects beneficial gut bacteria, stimulates bowel movements, and helps reduce constipation. Additionally, albedo contains hesperidin, a plant compound capable of preventing vascular disease and reducing inflammation, while also providing vitamins that support immune enhancement.
An analysis published in the U.S. National Library of Medicine (PubMed) indicated that the peel and white fibrous layer of citrus fruits contain more fiber and polyphenols than the fruit flesh, along with strong antioxidant capabilities.
A 12-week study conducted at Western Sydney University in Australia found that individuals who consumed tangerines with the white layer intact experienced a slower rise in post-meal blood sugar levels compared to the group that removed it. This finding is particularly beneficial for people with type 2 diabetes.

Retaining the albedo when eating tangerines helps maximize the intake of fiber and nutrients, aids digestion, stabilizes blood sugar levels, and enhances both cardiovascular health and the immune system.
The vitamin C content in the white layer and tangerine peel is comparable to or even higher than that in the fruit segments, contributing to the prevention of colds and winter illnesses. Albedo also contains flavonoids, which provide antioxidant support and help reduce bad cholesterol. Meanwhile, its soluble fiber promotes satiety, assists with weight control, and lowers the risk of obesity.
Experts suggest consuming the white layer whole after thoroughly washing it with vinegar or salt. Alternatively, dried tangerine peel can be used to make tea, preserving its valuable nutrients. For children under five years old, some albedo should be removed to facilitate easier chewing, while older children should consume the entire white layer to fully benefit from the nutritional value tangerines provide.
