The effect of using different types (yellow, white and purple) and rates (0.25%, 0.50% and 0.75%) of onion-water extract in meatball production on the various quality criteria of meatballs and the formation of heterocyclic aromatic amines (HCAs) was investigated.


It was determined that cooking process caused a reduction in the water content of meatballs as well as an increase in pH values. MeIQx, 7,8-DiMeIQx, 4,8-DiMeIQx, PhIP, AαC and MeAαC could not be detected in any of the analyzed meatballs, while IQx, IQ and MeIQ were determined in some of the samples.


The use of 0.25% and 0.50% white onion-water extract in meatball preparation inhibited the formation of IQx and IQ that were identified in the control group, but their quantities could not be determined. However, the use of water extract of varying types of onions in meatball preparation increased the total HCA content due to the increase of the MeIQ formation. In addition, it was determined that as the rate of onion-water extract for varying types of onions increased, the total HCA amount also increased. The total HCA amount of the meatballs varied between 0.05 and 0.1 ng g-1 . © 2019 Society of Chemical Industry.
