The cured color could be achieved by adding
from 20 to 40 ppm; however, in order to achieve cured flavor
as well, 30–50 ppm nitrite was needed. Thus, as a
whole, 50 ppm nitrite seems enough in respect to color
and flavor characteristics, and further amounts of nitrite
are needed to give bacteriological stability. This work is
in agreement with the studies conducted by Leistner et al.
(1980)
