Thread: Dehydrated meals and salt content

Your tables are wrong;
Edited as I misread your last column it's not Na it's salt.

The sodium (mg) per 100g is not dry weight, it's per 100g of prepared meal.

For roast beef & vegetables - Regular.
Dry meal weight = 175g
Prepared meal weight = 675g (add 500ml of water)
Sodium per 100g of prepared meal = 588mg/0.588g Weight of salt (NaCl) = 1.49g (Sodium x 2.54)
Sodium per serve (675g) = 3840mg/3.840g. Weight of salt (NaCl) = 9.75g (Sodium x 2.54)

Sodium per serve equates close enough to scaling the per 100g by 6.75 which would = 3969mg. Why the slight difference I don't know. Presume scaling or rounding somewhere.
