Peach gum (also known as peach resin or peach tree gum) is a natural gum and resinous substance secreted by peach trees (Prunus persica) and related species in the Rosaceae family when the bark is damaged or the tree is stressed.[1][2]
It has a long history of consumption in China, where it is commonly used in sweet soups, desserts, and beverages. The substance is marketed for various health benefits, including claims about collagen content and skin improvement,[1] though many of these claims lack scientific evidence.
Composition
The substance is primarily composed of polysaccharides, including galactose, rhamnose, and α-glucuronic acid.[4] It also contains dietary fiber, carbohydrates, proteins, and small amounts of vitamins.[2][1] Despite marketing claims, peach gum does not contain collagen, which is exclusive to animal tissues.[3]
Traditional use
Peach gum has been documented in traditional Chinese medicine texts, including the Tang Bencao (Tang Materia Medica) and Li Shizhen's Bencao Gangmu (Compendium of Materia Medica) from the Ming Dynasty.[4][3] Historical texts describe its use for treating urinary issues and other conditions,[4] though these traditional uses have not been validated by modern scientific research.
Culinary use
In modern times, peach gum is primarily used as a food ingredient, particularly in Asian cuisine.[1] It requires soaking in water for 8-12 hours before use, during which it softens and expands significantly.[1] Common preparations include:[1]
- Sweet soups and desserts
- Beverages combined with milk or soy milk
- Porridges and puddings
- Combined with other ingredients such as snow fungus, red dates, or papaya
The texture after preparation is described as gelatinous and slightly chewy.[1]
Regulatory status
In 2023, China's National Health Commission officially approved peach gum as a "new food ingredient," establishing a recommended daily consumption limit of ≤30 grams per day.[2] The regulatory approval noted insufficient safety data for infants, pregnant women, and nursing mothers, recommending these groups avoid consumption.[2]
