Sri Lankan processed meat industry produces a variety of meat products. Global meat
production and consumption have increased rapidly in recent decades, with harmful effects
on the environment and public health. Nitrite, nitrate, heme iron, and certain types of fats such
as trans-fats are potentially harmful compounds. The nitrite, nitrate, total fat, and heme iron
that exist in 12 processed meat products commonly available in the Sri Lankan market were
examined to get an idea about their availability in local products. The FAO classification for
semi-processed and processed meat products was followed in the study, and ten replicates
were included in the analysis. The Ready to Cook (RTC) processed meat samples were
procured and then cooked according to the standard procedures. The nitrite and nitrate content
were determined by AOAC 973.31 method, while total fat content was determined using
AOAC 963.15 method on fresh weight basis. The heme iron content was analyzed using
acidified acetone extraction method. The results were statistically interpreted using analysis
of variance and Duncan's multiple range test at 0.05 significant level. The Ready to Eat (RTE)
bacon and RTE salami had the highest nitrite (7.25 mg/kg) and nitrate content (89.66 mg/kg),
respectively. The RTE burger and RTE jerky had the lowest content of nitrite (0.99 mg/kg)
and nitrate content (1.85 mg/kg), respectively. The raw-cooked beef products (15.80%) and
dried chicken products had the lowest percentage (3.49%), and fermented beef sausages had
the highest percentage (26.41%) of total fat compared to the other types of processed meat
products used in this study. The raw-cooked chicken products had the lowest content (0.33
mg/100 g), and the dried beef products had the highest content (5.40 mg/100 g) of heme iron
compared to the other selected processed meat products. In conclusion, the cured and
fermented meat products commonly available in the Sri Lankan market consist of
comparatively higher amounts of nitrite, nitrate, fat, and heme iron than the freshly processed
and dried meat products |
