Abstract
We evaluated the physicochemical and storage characteristics of Hanwoo Tteokgalbi treated with onion skin powder (OSP) and blackcurrant fruit powder (BFP). The experimental design included seven treatments: a control (ascorbic acid 0.1%), T1: OSP 0.3%, T2: OSP 0.6%, T3: BFP 0.3%, T4: BFP 0.6%, T5: OSP 0.15%+BFP 0.15%, and T6: OSP 0.3%+BFP 0.3%. The OSP was higher in both polyphenol and flavonoid contents compared to BFP (p<0.05). The moisture and ash contents of all Tteokgalbi samples with a large amount of added natural antioxidant powder (0.6%) were higher than those with small amounts of added antioxidant (0.3%). The cooking loss and water holding capacity were outstanding in the T2 treatment compared to the others (p<0.05). The lightness, redness, and yellowness values were reduced on the addition of 0.6% antioxidant powder (p<0.05). The springiness and cohesiveness values of the Tteokgalbi samples were higher for the 0.3% addition than the control and 0.6% addition (p<0.05). The Tteokgalbi samples with natural antioxidants showed similar sensory attribute scores compared to the control. The pH values reduced as the BFP increased (p<0.05), and the total microbial count increased after OSP addition. The 2-thiobarbituric acid reactive substance values of the samples treated with OSP were significantly lower than the control after day 10 (p<0.05). As a result, the addition of OSP or BFP did not have a significant negative influence on the quality characteristics of Hanwoo Tteokgalbi. In particular, the addition of 0.6% OSP was effective in increasing water retentivity and inhibiting lipid oxidation.
