How far can we reduce the salt content of cooked meat products?

A study has shown that it is possible to reduce salt content in ham without affecting key phenomena for product quality.

Companies are reducing salt content in their products to respond to a public health issue. A target product is high quality cooked ham, which is the the most consumed cooked meat product in France. But how far can we go in this salt reduction without affecting the quality of the product and the process yield?

The work has focused on the heat treatment and on two key phenomena for the quality of ham: adhesion between muscles, which determines the cohesion of the slice of ham, and mass transfer, which defines the cooking yield. The study has analyzed the phenomena responsible for adhesion. The mass transfer was also modeled in the conditions which are applied during the manufacturing of low salted meat products. Results prove that it is possible to reduce to 0.8% the salt content in the ham at lab-scale – instead of 1.8% which is the current average – without affecting either the performance of the operation, or the adhesion between the pieces of meat.

Transposing such a result to industry requires taking into account the effect of the prior mechanical treatment of the muscles (tumbling). On the other hand, a combined model of heat-mass transfer and of microbial inactivation was developed to optimize the performance and the microbiological safety of slightly salted cooked meat products. Further research needs to be done in order to better understand the effect of salt reduction on the organoleptic and technological qualities of end products.
