Abstract
This study aimed to investigate the influence of Astragalus membranaceus (AM), Adenophora triphylla (AT), and Ulmus pumila (UP) extracts on the quality traits, palatability, and storage stability of sous-vide (SV) cooked chicken breasts. Chicken breasts were marinated in AM, AT, or UP extracts for 1 h, and then consistently cooked at a constant temperature of 60°C for 2 h. SV cooked chicken breasts with the UP extract exhibited lower lightness and higher yellowness values on the surface region compared to those with the AM and AT extracts (p<0.05). The control and UP groups displayed a similar overall visual acceptability (p>0.05), although the UP group had lower color acceptability (p<0.01). The UP group also had higher flavor and lower off-flavor intensities compared to the control group (p<0.05), although similar scores were observed in tenderness attributes and juiciness among the groups (p>0.05). Owing to these results regarding overall sensory acceptability, samples from the UP group were more preferred by the trained panelists compared to samples from the control group (p<0.001). On 14 d of cold storage, all the groups with herbal medicinal extracts exhibited a lower concentration of thiobarbituric acid-reactive substances than the control group (p<0.05), and the AT and UP groups showed lower values compared to the AM group due to their higher flavonoid contents (p<0.001). Therefore, meat marination with herbal plant extracts before SV cooking can be effective for enhancing the overall quality of SV cooked chicken breast.
