Quality characteristics of frankfurters influenced by lard-based diacylglycerol containing catechin during storage at 4 °C.
Frankfurters formulated with either lard or diacylglycerol (DAG)-rich purified glycerolytic lard (PGL), with or without catechin, were vacuum-packed and stored at 4 °C for 28 days to evaluate their physicochemical and sensory properties. Results revealed that lard-based frankfurters exhibited significantly higher cooking loss (8.69 %) and released fat (0.63 %) compared to PGL-based frankfurters (5.13 % and 0.33 %) (P < 0.05). Over time, lard-based frankfurters experienced greater deterioration in color, texture, microstructure, and sensory quality, along with increased fat oxidation (0.18 to 1.54 mg/kg) and microbial growth (3.77 to 5.43 Log CFU/g) (P < 0.05). Notably, substituting lard with PGL significantly enhanced the L*-value, b*-value, texture, microstructure, and sensory quality during storage (P < 0.05). Furthermore, the inclusion of catechin in frankfurters further reduced cooking loss (8.69 to 6.74 % and 5.13 to 3.89 %) and released fat (0.63 to 0.54 % and 0.33 to 0.16 %) (P < 0.05) while improving color, texture, microstructure, and sensory quality (P < 0.05). Catechin also effectively inhibited fat oxidation (1.54 to 1.34 mg/kg and 1.86 to 1.51 mg/kg) and microbial growth (5.43 to 5.27 Log CFU/g and 5.37 to 5.09 Log CFU/g) in frankfurters during storage (P < 0.05). Overall, the incorporation of DAG and catechin improved the quality and shelf life of frankfurters during storage.
期刊介绍:
The aim of Meat Science is to serve as a suitable platform for the dissemination of interdisciplinary and international knowledge on all factors influencing the properties of meat. While the journal primarily focuses on the flesh of mammals, contributions related to poultry will be considered if they enhance the overall understanding of the relationship between muscle nature and meat quality post mortem. Additionally, papers on large birds (e.g., emus, ostriches) as well as wild-captured mammals and crocodiles will be welcomed.
