2. Key points for preserving different varieties of radish
| Radish type | optimal storage temperature | storage period | Things to note |
|---|---|---|---|
| white radish | 0-4℃ | 2-3 months | Need to keep dry |
| carrot | 0-5℃ | 1-2 months | remove tassel |
| green radish | 1-3℃ | 3-4 weeks | avoid frostbite |
| carrot | 2-5℃ | 4-6 weeks | Store separately |
3. 5-step professional preservation process
1.Preprocessing:Fresh radishes need to be dried for 1-2 days to evaporate surface moisture, but they should not be exposed to the sun. Keeping 1-2cm of the stem can extend the shelf life.
2.Hierarchical filtering:Damaged radishes are preferred for consumption, while intact and scar-free radishes are suitable for long-term storage. Radishes weighing more than 500g each have better storage stability.
3.Environmental control:The ideal humidity is 85%-90% and the temperature is 0-4℃. One small package of food desiccant can be placed for every 10kg of radish.
4.Isolated storage:Do not place them with fruits that release large amounts of ethylene, such as apples and pears, as this will cause radish to sprout and deteriorate.
5.Regular inspection:Check once a week and take out any soft and rotten radishes immediately to avoid mold infection.

| method | cost | Freshness preservation effect | Operation difficulty |
|---|---|---|---|
| Nano fresh-keeping bag | higher | Extend the time by 2 times | Simple |
| vacuum freezing | medium | 95% nutrition retention | Equipment required |

5. Frequently Asked Questions
Q: Can sprouted radishes still be eaten?
A: Recent hot search data shows that slightly sprouted radish can still be eaten after removing the buds, but its nutritional value is reduced by about 30%.
Q: What is the best way to freeze and preserve radishes?
A: It is recommended to cut into pieces, blanch them and then freeze them quickly. They can be stored for 6 months. Direct freezing will cause cell rupture and the taste will deteriorate after thawing.
Q: How to tell whether a radish has gone bad?
A: It should be discarded if the following conditions occur: ① There are black ring-shaped lines on the cut ② It smells of alcohol ③ The texture is soft and watery.
6. Expert advice
According to the latest research from China Agricultural University, the "sandwich preservation method" has the best effect: spread kitchen paper on the bottom of the container → place radishes → cover dry tea leaves → seal and refrigerate. This method can maintain the crispness of radish for more than 45 days, and the vitamin C loss rate is less than 15%.
Mastering these scientific preservation methods and cooperating with the recently popular "segmented purchase" strategy (that is, buying a weekly consumption at a time) can not only ensure the freshness of the ingredients, but also avoid waste. Remember not to wash before storing, keeping dry is key!
