Another useful technique for preservation is to vacuum-pack the rice, a practice possible thanks to the use of domestic vacuum bags that are now easily found on the market. In this case, remember, however, that vacuum-packing does not sterilize the food and therefore, before sealing it, remember to check that it is still in optimal conditions.
Alternatively, rice can also be frozen, an excellent way to preserve it for the long term. When frozen, especially if vacuum-packed, it can be stored for long periods without deteriorating, thanks to the low water activity in the grains which prevents the formation of harmful ice crystals. Again, remember to label it with the dates so you know when you put it away and when it should expire.
