Abstract

GOMEZ-SALAZAR, Julián Andrés; CLEMENTE-POLO, Gabriela  and  SANJUAN-PELLICCER, Neus. Review of mathematical models to describe the food salting process. Dyna rev.fac.nac.minas [online]. 2015, vol.82, n.190, pp.23-30. ISSN 0012-7353.  http://dx.doi.org/10.15446/dyna.v82n190.42016.

Salting and subsequent curing are part of the traditional processing method used in the meat and fish industry. Different preserving agents (sodium chloride, nitrite, nitrate, among others) are added in this process. Nowadays, more attention is paid to the amount of salts added and the salting time employed. For this reason, it is important to know the factors governing salt penetration and the most convenient process conditions. The transfer mechanism of the salts through the structure is an interesting aspect in meat and fish processing technology. Mathematical models are the best way to discover the factors, which govern this process, which may represent and explain the observed data and predict the behaviour under different conditions. The objective of this review is to describe the use of the mathematical models to simulate meat and fish salting and the benefits derived from their use. Most of the models used to describe the salting process are diffusional, based on Fick's second law, although empirical ones are also used. For modelling purposes a good description of the experimental results should be guaranteed. The complexity of the model will depend on the objective to be reached and will be analysed in each case.

Keywords : meat; fish; salting; curing; modelling.
