Abstract

Abstract: The objective of the study was to investigate the effects of coenzyme Q10 (CoQ10 ) and sodium succinate (SS) on the redness and thiobarbituric acid reactive substances (TBARS) of minced pork under 4 ± 1°C for 9 days. Different dosages of CoQ10 and SS were added to the minced pork, respectively. The results showed that CoQ10 or SS addition could retard the decrease of a * value effectively. The TBARS value decreased significantly with CoQ10 (0.002%–0.008%) or SS addition. The optimal levels of CoQ10 and SS addition were 0.006% and 0.04%, respectively. Compared to adding individually, the combination addition of 0.006% CoQ10 and 0.04% SS could make the a * value of minced pork more stable during storage, while the TBARS value and metmyoglobin content decreased significantly ( p < .05). CoQ10 and SS can be used to improve the color stability of minced pork during storage by inhibiting lipid oxidation and metmyoglobin formation. Practical applications: The discoloration of minced pork during storage affects edible quality and commercial value seriously. The process of color change can be effectively delayed by adding various antioxidants. Due to potential health risks of synthetic antioxidants, the demand for natural antioxidants has been increased. Coenzyme Q10 is one of the most consumed nutritional supplements, and succinate can improve meat color stability as a Krebs cycle substrate. The combination addition of coenzyme Q10 and sodium succinate can retard redness decrease, as well as inhibit lipid oxidation of minced pork during refrigerated storage. The practical implication of this study is that coenzyme Q10 and sodium succinate can be used as promising food additives to improve color stability and extend shelf life of meat or meat products.
