Safety Overview
1.Tangerine Peel — Overview
Tangerine Peel, derived from Citrus reticulata, is an integral part of the Rutaceae family, renowned globally for its aromatic and medicinal properties. This small to medium-sized tree typically reaches heights of 3 to 6 meters, characterized by its dense canopy of glossy, dark green, elliptical leaves, measuring about 4 to 10 cm in length with smooth, entire margins. The plant produces delicate white to light yellow flowers, each approximately 2 to 4 cm wide, featuring five petals arranged in a distinctive star-like pattern.
The bark is generally smooth and grayish, though it may develop a slightly rougher, fissured texture with increasing age. The fruit itself, the tangerine, is typically small, vibrant orange, and notably easy to peel, averaging 5 to 10 cm in diameter, containing 7-14 juicy, sweet segments. The peel, a rich orange hue, is particularly significant due to its potent citrus aroma and oily surface, indicative of its high essential oil content.
Originally native to subtropical Southeast Asia, particularly southern China, Citrus reticulata thrives in warm, humid climates, preferring well-drained, sandy or loamy soils and abundant sunlight. Its adaptability has led to widespread cultivation across similar climatic regions globally, solidifying its status in both culinary and traditional medicinal practices, especially as 'Chenpi' in Traditional Chinese Medicine.
