ABSTRACT
Red ginger and red galangal contain antioxidant compounds that can be added into edible coating. This study aims to obtain the best addition of red ginger and red galangal essential oils in chitosan edible coating on quality, oxidation damage, and shelf life of smoked catfish. The study used a completely randomized design consisting of four treatments and four replications. The treatments consisted of P0 (without edible coating chitosan), P1 (addition of 1% red ginger essential oil), P2 (addition of 1% red galangal essential oil), and P3 (addition of 0.5% red ginger essential oil + 0.5% red galangal). Smoked catfish were stored for 14 days at room temperature and observed on days 0, 7, and 14. The parameter observed on the edible coating was antioxidant activity and on the smoked catfish were water content, ALT, TBA, color, and sensory assessment. Data were analyzed statistically using analysis of variance (ANOVA) and continued with the DNMRT at 5% level. The best treatment was P2 treatment which met the quality standards of smoked fish according to SNI 2725-2013. The IC50 value was 57.24 μg/ml with strong antioxidant activity. The results showed that smoked catfish P2 on day 14th has a water content value of 22.89%, TBA value 0.41 mg malonaldehyde/g, ALT test 4.66 log CFU/g on the 7th day, color analysis L* 33.10, a* 3.81, and b* 8.78. Descriptive sensory assessments of P2 treatment were brown, smelled of red galangal, hard texture, hedonic assessments of color was 3.73, aroma 3.70, and hardness 3.70 (liked).
