아질산염 대체제로 치자 추출물의 첨가가 닭고기 패티의 품질특성에 미치는 영향

초록

This study investigated the effect of substitution of nitrite with Gardenia jasminoides extract (GJE) on quality characteristics of chicken meat patty. Samples were prepared with five different treatments (n = 5; control : no GJE or sodium nitrite (SN); T1 : 200 ppm SN; T2 : 0.5% GJE + 150 ppm SN; T3 : 1.0% GJE + 100 ppm SN; T4 : 1.5% GJE) and then stored for 9 days at 4℃. The pH value decreased significantly (p < 0.05) with the increase in the addition level of GJE. Higher (p < 0.05) 2-thiobarbituric acid reactive substances (TBARS) content was observed in the groups with a higher level of added GJE and T4 showed the highest (p < 0.05) TBARS content after 3 days. Peroxide value was higher (p < 0.05) in T4 than in T1, T2, and T3 at day 9. T3 and T4 showed lower (p < 0.05) L* (lightness) value and higher (p < 0.05) a* (redness) and b* (yellowness) values compared to that in the control and T1. Water-holding capacity (WHC) declined faster (p < 0.05) in T3 and T4 than in the other groups during storage. These findings suggest that GJE added as a substitute for SN adversely affects the lipid oxidation stability and WHC; however, it improves the red color in chicken meat patty.
