[[Curing food]]
'''Food preservation''' is inseparable from where the food is stored. The '''storage of food''' is done in a suitable environment. This often means a dry, cool place. There are several places in which food can be stored. These include [[Food storage rooms]] as pantry's (rooms in the house, near the kitchen) or separate food storage rooms (ie above ground, [[Earth berming|earth bermed]], or even underground (ie [[root cellar]]s; store rooms, even mere burial is possible) ). As such, at least 1 food storage technique is often employed (cooling). The following list describes the food preservation techniques we can use:

[[Storing foods]]
It should be noted however that each foodstuff is more suitable to one or another type of food storage (not all types are suitable for every foodstuff). Tuberous root crops for example are best stored in a moist environment (as these crops are still alive and able to take up water). They can be buried in buckets filled with wet sand and stored below (see "root cellar") or above ground (ie during winter). As each food storage technique requires special equipment, the crops grown in each community are best selected carefully so that as little as possible different storage techniques are needed (hence allowing more cost-effective food storage).

Food preservation is inseparable from where the food is stored. The storage of food is done in a suitable environment. This often means a dry, cool place. There are several places in which food can be stored. These include Food storage rooms as pantry's (rooms in the house, near the kitchen) or separate food storage rooms (ie above ground, earth bermed, or even underground (ie root cellars; store rooms, even mere burial is possible) ). As such, at least 1 food storage technique is often employed (cooling). The following list describes the food preservation techniques we can use:

It should be noted however that each foodstuff is more suitable to one or another type of food storage (not all types are suitable for every foodstuff). Tuberous root crops for example are best stored in a moist environment (as these crops are still alive and able to take up water).

Examples

  • Canned vegetables and canned beans
  • Bulk dried foods such as flour, milk powder, soya powder, whole grains (brown rice, white rice, ...)
  • Noodles [3]
  • jam (cooked, sugared fruit, with chunks of fruit, pulp) & jelly (cooked, sugared fruit, strained)

  • Frozen fish/seafood/meat analogues (tofu, seitan, tempeh)/eggs, frozen vegetables
