Effect of the fortification with astaxanthin on the quality parameters and heterocyclic amines content of meatballs

Abstract

SummaryHerein, effects of astaxanthin usage on some quality parameters of meatballs and heterocyclic aromatic amines (HAAs) formation were investigated. The water content of meatballs with 1% of astaxanthin exhibited significantly (P < 0.05) lower water content than other groups. The pH values of the samples were significantly (P < 0.05) reduced due to astaxanthin addition; the higher the concentration used, the lower the pH value. Astaxanthin addition improved the oxidative stability and the colour properties of meatballs since the fortified samples exhibited significantly (P < 0.05) lower thiobarbituric acid reactive substances and L* values and higher a* and b* values than the control samples in a non‐dose dependent manner. Only MeIQx was detected in meatballs cooked at 150 °C, the major compound in the other groups. The total HAAs content of meatballs ranged from 0.18 to 7.28 ng g−1, and it increased with increasing the cooking temperature. Astaxanthin addition inhibited or promoted HAAs formation depending on the cooking temperature. An increase (94–244%) in the total HAAs content was observed in the meatballs cooked at 150 °C, whereas a reduction of 47–54% in the total HAAs of those cooked at 200 °C was observed. Thus, astaxanthin could be recommended in producing of meatballs that will be cooked at 200 °C.
