6.8 grams / 454 grams x 100 = ~1.49% salt
Because the nitrite is 1% of the salt, and we want about ~150 Ppm nitrite in the meat, 454 x 0.000150 / 0.01 = 6.8 grams per pound of meat...
Ready cure is unique in that at 6.8 grams addition to 1# of meat, or 1# of stuff, will yield a product that is safe in nitrites and at 1.49%
salt, that's a fair/good amount of salt for the palate....
This is what I would use for injecting a turkey or Canadian Bacon... I'm cutting back on salt.... For adding to fresh sausage, I would use the 6.8 grams per pound for the same reason...
Now for a rub on some meats, for a dry cure, like in a controlled atmosphere, a minimum of 2.5% salt, usually 3% is rubbed into the meat to aid in bacterial control as the meat dries.. Some dry rub curing you can add additional nitrite.... up to 625 Ppm nitrite because it dissipates over time..... and those methods usually call for 2, to sometimes 3 rubbings of salt and nitrite over a several week period of time... 150-200 Ppm ingoing nitrite per rub using 3 rubs..... not to exceed 625 Ppm in total...... like country hams.. of course it depends on which recipe you follow... dry curing some products at a temperature of ~50ish deg. F you should use cure #2.. the nitrate reacts with bacteria in the meat to convert to nitrite over time, thus keeping the meat safe to eat..... The first step in this type curing calls for refrigeration... the nitrite in the cure #2 takes care of the short term bacterial control... the nitrate then takes care of the long term bacterial control along with the salt.....
There is no one cure recipe that fits all scenarios of curing... One has to be familiar with different techniques and follow those recipes specific to those parameters...
Seems each country has developed certain guidelines for each process... EU, Canada, US etc... that's why there are different amounts of nitrite in each countries cures....
I pay particular attention to regs. here in the US and sometimes I'm not sure if I'm getting confused with all the different terminologies etc... Our government seems to like to muddy the water by over regulating, having more than one agency in charge and the agencies have no inter agency communication, so they don't know what the others are doing... FDA, USDA, FSIS and HAACP, all control food in one way or another.. OK, there's my disclaimer as to WHY I seem to get confused....
