Can You Vacuum Seal Spices?

Yes, it is totally healthy for you to vacuum seal your spices in the kitchen. When done in the right way, vacuum sealed spices will stay fresh for a long time.

How to Vacuum Seal Spices

Have your set of spices, the vacuum seal machine and your accessory ready either vacuum sealer bags or mason jars.

Put your spices in the bag or jar and follow instructions on the vacuum seal machine until your spices are fully sealed. To ensure the jars are well sealed, the center of the lid should be depressed.

Once sealed, store them in the refrigerator or freezer.  This extends their durability as vacuum seal alone will not keep them preserved. Always ensure the spices are in the freezer or refrigerator when not in use.

Mason Jars or Vacuum Sealer Bags for Spices?

Vacuum sealer bags are well known in vacuum sealing food but are they the right choice for your spices? For spices, mason jars will work better than the sealer bags. This is because spices are in form of small particles which make it difficult for them to be fully sealed in the bags.

Glass mason jars are preferred in storage than plastic jars. Glass will extend the viability of the spices longer than the plastic. Plastic jars can at times allow air into the jars which will damage the spices over the time.

When using mason jars, use lids for jars not bands since they lock more therefore keeping the container airtight. To add to that, have the appropriate lid sizes depending on the jar sizes. Vacuum Sealing Spices in Oil

Spices such as rosemary can be vacuum sealed in oil when raw. This is achieved through adding oil to the spices, vacuum sealing them and eventually freezing them.

This method is more efficient but does not work for most spices since oil cannot be added to grounded spices. It is more efficient in that;

  • Your spices are preserved indefinitely without losing their quality.
  • Usage is easier since the frozen oil will melt quickly than the iced spices.
  • The oil ensures the flavor of the spices is retained for longer than normal vacuum sealing.

Once vacuum sealed, your spices will stay preserved but the fresh nature can be lost after use. To avoid this, caution should be take each time you unseal the spices.
