Introduction

Salt is used in different doses depending on storage needs. At 2% (by mass), it slows the development of certain microorganisms and will bring a salty taste. On the other hand, in high doses, it will destroy almost all of the microorganisms. By reducing the product's water activity,

this process slows or stops microbial development. There are two systems: salting (or salting) and brining. These

techniques are used in cheese making, delicatessen and for certain species of fish (herring, salmon ...). Finally, according to traditional recipes, smoking can be associated with it.

Étape 1 - Preamble

Some pre-harvest foodstuffs require pre-processing

(for meat, fish ...)

Étape 2 - Method of preservation

For the meat is rubbed with salt and wood ashes and repeated

several times over several days. The layer of ash helps to absorb

moisture and salt to absorb water from food, which makes the

foods that are stored for a long time and are difficult to break down. Compress and repeat several times. Store in a closed container.
