How much salt and pink salt (in grams) do I need for 50kg of pork sausages?
I have worked out for 50kg of pork meat I will need 1200g of salt and 155g of pink salt. Is this correct?
According to Smoking Meat Forums, you would need 2 ounces of pink salt for 50 lbs of sausage, which is a ratio of 0.0025 pink salt to meat (they provide three significant digits) for short curing time sausages. These are sausages which will be cooked or smoked.
Therefore, converting to metric, 50 kg, you would require 125 grams or so pink salt.
Note that the regular salt is not really a curing agent at concentrations used in this type of sausage, but for flavor and texture:
Although salt is not generally used in concentrations sufficient to effect preservation it exerts some antimicrobial activity. Some bacteria are already inhibited at 2 percent levels of salt. Other microorganisms tolerate a much higher concentration of salt.
You would need to provide an original recipe or formula on which you have based your calculations to get any validation of your computation of the regular salt amount.
Officially, you want 2% salt and 1/9th of that Pink salt. Although for fresh sausage you may find that a bit salty. 1% or 1.5% maybe taste better and be healthier.
modern medicine is now onboard with cancer caused by Nitrites. If your meat is clean, from a good source and not from 100 different pigs, consider skipping the pink stuff.
Salt IS indeed a curing agent, just not at 2%.
