Chenpi has a shelf life, but the specific duration is affected by storage conditions and quality. It is usually recommended to use it within 3-5 years to ensure the best quality. The following are specific instructions:
Key conclusions
Shelf life range
Under normal storage conditions, the shelf life of tangerine peel is generally 2-5 years.
The best use period is 3-5 years, when the efficacy and aroma are in the best state.
If it is stored for more than 10 years and improperly stored (such as humidity and high temperature), it may become moldy, worm-eaten or have a strange smell and needs to be discarded.
Influencing factors
Storage method: Dry, cool, and sealed environment can extend the shelf life; humidity or direct sunlight will accelerate deterioration.
Raw material quality: High-quality tangerine peel (such as Guangdong tangerine peel) is more resistant to storage, and ordinary citrus peel has a poor aging effect.
Methods to determine whether it has deteriorated
Appearance: mold, discoloration or traces of worms.
Smell: Loss of orange fragrance, musty or sour smell.
Touch: damp, soft or overly dry.
Differences between traditional perception and actual storage
Although traditionally, it is believed that "the older the tangerine peel, the better", this statement is based on professional aging conditions (such as constant temperature and humidity, regular turning and drying). It is difficult to meet the standards for home storage, and long-term storage by yourself may lead to the loss of efficacy or the risk of deterioration.
Recommendation
Prioritize the purchase of finished tangerine peel (such as Xinhui tangerine peel) from regular channels, and the shelf life is usually marked on the packaging.
Use sealed cans for daily storage and check the status regularly.
