Chenpi is a dried product, and the best‑before date is a reference. Usability depends on storage conditions and actual condition.
Practical Checks
- Appearance: Dry, free of mold, and no insect damage.
- Aroma: Natural aged citrus scent, no sour or off‑odors.
- Texture: Not damp, sticky, or unusually soft.
Storage Matters
Humid, hot, or poorly ventilated storage increases the risk of spoilage.
In short, the date alone is not decisive. If anything seems questionable, it is safer to discard it.
