Question 1: Will the saffron collection expire? There is no fixed limit on the shelf life of saffron, and the effect varies with individual preservation methods. The shelf life is generally 2-5 years. If it is more than five years, it is considered that it can no longer be used, which is not only ineffective, but also likely to be moldy.

Crocus, formerly known as crocus, also known as crocus, etc. In addition to beautiful appearance and ornamental value, it also has a strong fragrance, which is used by people to make spices. Of course, its most important function lies in its medicinal value. According to Diet, saffron is "gloomy and stuffy, and it makes people happy after eating for a long time." . In addition to ancient records, modern medical research found that saffron is also rich in vitamins, carotene and other trace elements. Can be used for preventing and treating cardiovascular and cerebrovascular diseases, menoxenia, traumatic injury, neurasthenia, etc.

Saffron preservation

1, moistureproof. The best moisture-proof effect is to seal off the air. Because once exposed to the air, saffron is easily affected by moisture in the air and becomes damp and moldy, which leads to the qualitative change of saffron and seriously affects its use effect and shelf life.

2, shading. Attention should be paid to avoid exposure to sunlight during storage of crocus sativus, because some studies have shown that once crocus sativus is exposed to light, it is easy to produce chemical reactions and molecular recombination, thus affecting its due efficacy.

3. Refrigeration. When stored at home, saffron can generally be sealed and stored in refrigerator and safe room. As we all know, the lower the temperature, the slower the molecular activity, which can effectively prevent saffron from deteriorating too fast, thus extending its shelf life.

Question 2: How many years can dried saffron be stored? How to judge whether it is invalid? As long as it is not moldy, discolored or infested, it will be fine if it is stored for decades.

Question 3: Saffron has not been soaked in water for more than three years. Is it out of date? Iran brought it back with fakes. Now the market is so chaotic that counterfeiting is very common. Even if it expires for more than three years, the real saffron will still have color. I often drink saffron myself.

Question 4: How to tell whether the saffron has expired? If it is unprocessed, the shelf life of saffron is about 5 years. Don't worry, it won't expire unless there is an accident.

Question 5: Will expired saffron make tea thirsty? This is not recommended.

Question 6: The saffron has expired, but it is not moldy, just a little damp. Does it still work? The best storage methods of saffron are shading, sealing and refrigeration. If properly preserved, it can generally be preserved for 1 ~ 2 years without affecting the quality and efficacy. Four years is indeed a long time, but it can still be used if it is not spoiled, moldy and faded. It is suggested to soak saffron wine, and about 2g saffron should be used for 1 kg liquor, which can be drunk after soaking for one week. To buy saffron, I suggest you go to a big drugstore or an old-fashioned drugstore, such as Tongrentang, where saffron costs 70 ~ 100 yuan per gram. The situation varies slightly from place to place. Although the price is higher, it can be guaranteed to be genuine. Other small pharmacies have no saffron or no real saffron. Many small pharmacies sell saffron as saffron, and some sell it directly to you. If you are familiar with online shopping, I recommend you to look at the "Saffron Beauty and Health Pavilion" on Taobao. They have 8 years of experience in the saffron industry and have their own saffron planting base. The saffron they sell is of high quality and low price. Iranian imports premium saffron 25 yuan per gram and domestic premium saffron 35 yuan per gram.
