It is generally not recommended to store chenpi in direct sunlight by a window. Strong light and heat can affect appearance, aroma, and stability.
Possible effects of direct sunlight
- Color changes
Prolonged exposure can cause fading or dullness, reducing visual quality.
- Faster oxidation and drying
Heat and light speed up oxidation and moisture loss, making the peel overly dry and brittle, and less stable in flavor.
- Aroma loss
Aromatic components are more likely to volatilize under heat and light, leading to a weaker aroma.
Better storage practice
Store in a cool, dry, ventilated place. Use light-shielding containers or packaging and avoid moisture and strong odors. Check periodically; if dampness or off-odors appear, a brief, gentle airing or light sun-drying can help, while avoiding harsh direct exposure.
