Summary
Bouillons are dehydrated broths formed into a small cube or
granules that can be prepared from bovines, chicken, duck or
lamb. Adding nitrite to meat is a common process that helps
the delaying of botulinal toxin development. It also
stabilizes the red meat color and retards the development of
oxidative rancidity, off-odors and off-flavors during
storage. However, nitrite remaining in cured meat, known as
“residual nitrite”, is suspected as also being a health
risk. Given that nitrate and nitrite addition to meats is
legal, there is need to detect the nitrite content of meat
and meat-based products. This study was aimed to detect
whether there was any total nitrite content (nitrite
contamination and residual nitrite) in bouillons and to
estimate possible toxicological risks. For this purpose, 20
bouillon samples (bovine- and chickenbased), in cube or
granule form, were randomly collected from markets in
Ankara, Turkey. For the detection of nitrite contamination
of the samples, Griess method was used with slight
modifications. The nitrite in bovine- and chicken-based
bouillon samples was obtained as 3.288±1.145 mg/g and
2.622±0.828 mg/g, respectively. It can be concluded that
bouillons and other processed meat products should be
consumed attentively because of the detrimental effects of
the nitrite on the general population and particularly in
vulnerable groups such as young children and the elderly.
