How to preserve fresh hazelnuts

I believe everyone is familiar with hazelnuts, and many people like to eat this kind of nut. Although hazelnuts are delicious and nutritious, if you can't finish eating them in time, you still need to take reasonable measures to preserve them. Because if the hazelnuts are not stored properly and get damp, their taste will be greatly affected. So, how to store fresh hazelnuts? Here I will introduce you to the specific preservation method!

1. Storage conditions of hazelnuts

Hazelnuts have an extremely low moisture content, only 3.5% to 7%, and are relatively durable in storage. However, hazelnuts are sensitive to temperature and humidity. During storage, if the temperature exceeds 20℃ or the nuts are exposed to light for a long time, the fat conversion will be accelerated and a "rancid smell" will be produced, making the nuts inedible. If the humidity is too high (relative humidity of the air is over 75%), the nuts will become moldy. Therefore, the storage conditions for hazelnuts are low temperature, low oxygen, dryness and avoid light. Suitable conditions are temperatures below 15°C, relative humidity below 60%, and dim light in the warehouse. Nuts can be stored for 2 years without deterioration.

2. Sealed storage of hazelnuts

The safest way to store dried fruits is to place them in a sealed container. Glass bottles are better than plastic bottles. Glass is stable and will not volatilize harmful substances. The glass bottle must be dry and clean before putting dried fruits in it.

3. How to prevent moisture from falling hazelnuts at home

A key issue in storing hazelnuts is that they are easily affected by moisture. Dried tea leaves have a good ability to absorb water and prevent moisture. Therefore, it is recommended to put a small amount of tea leaves in the uneaten hazelnuts at home to prevent moisture absorption. However, tea leaves have their own fragrance, and it is not advisable to put too much tea leaves to affect the fragrance of the hazelnuts.

4. How to store large quantities of hazelnuts

1. Storage with desiccant

If you store a lot of dried fruits, you should use desiccants appropriately to achieve the best storage effect. However, desiccant should not be eaten, especially out of reach of children to avoid accidental ingestion.

2. Carbon dioxide preservation

Now spread a layer of plastic sheet on the ground, stack the hazelnuts on the plastic sheet, and then cover the pile of hazelnuts with a layer of plastic cover. The edges of the upper and lower plastic sheets overlap, compact them with sand, and then flush carbon dioxide from the bottom. This is a limited measure to prevent hazelnuts from deteriorating in summer.
