Until we get positive credible confirmation that the assumptions used in this technique are valid I think we should be very careful in suggesting on this forum that it is used. The basic questions that I have at the moment are:
The assumption that the only uptake of Nitrite will be that which is directly proportional with the weight increase of the meat. This does not seem to take into account:
- Simple diffusion of the highly concentrated brine throughout the existing interstitial meat fluids - thus not necessarily leading to an increase in weight.
- Any selective uptake or blocking of nitrite by intact cells
- The effect of large scale cell rupture if meat had previously been frozen - this is likely to increase the effects of simple diffusion
The accuracy of the weighing of the meat when measuring any weight increase that does take place - consistency between weighing
- If you do assume that the only uptake of Nitrite is directly proportional to the increased meat weight (??) then a 5% inaccuracy in the weighing would result in a 50% difference in the resulting cure concentration.
No apparent supporting documentation that shows this method reliably produces the expected residual levels of Nitrite in the end product.
I am happy to revise my opinion though if the evidence is forthcoming.
