The author previously reported that the addition of inuloprebiotics to broiler diets produces growth performance that is superior to antibiotic supplementation. The present study furthered this work by evaluating the quality with thiobarbituric acid reactive substances (TBARS) of the meat from chickens fed inuloprebiotics produced using Korean Jerusalem artichoke. Male Ross 308 broilers (n=240) were randomly allotted to a 35 day regimen of dietary control (no supplementation), dietary antibiotics supplementation (8 mg avilamycin/kg diet), or dietary inuloprebiotic supplementation (450 mg inuloprebiotics/kg diet). The pH, water holding capacity, L*value (lightness), and b*value (yellowness) of the chicken meat weres ignificantly higher in the inuloprebiotic group. The TBARS value of chicken meat stored at low temperature tended to increase according to the length of storage, and was significantly lower in the inuloprebiotics group. The sensory scores of the cooked chicken meat were significantly higher in the inuloprebiotics group. The results indicate that the addition of inuloprebiotics as anantimicrobial agent to broiler diets can greatly improve the quality and self-life with reducing TBARS of chicken meat.

돼지고기 등심의 표면에 Lcatococcus lactis subsp lactis ATCC l1454 유산균 배양액 3.96 log units의 처리구는 4℃ 저장 1일 이후 대조구의 TBA가와 유의적 차이가 없었다 (P>0.05). 유산균 배양액 3.96 log units 처리구의 Hunter color L^*과 b^*가는 저장 동안 대조구와 유의적 차이가 없었다. 그러나 유산균 배양액 4.10과 4.23 log units 처리구의 Hunter a^*가는 4℃ 저장 1일과 6일 이후 대조구와 유의적 차이 (P<0.05)를 나타내었다. 유산균 배 양액 4.10과 4.23 log units 처리구의 육즙유출율은 4℃ 저장 4일 이후부터 처리구와 대조구 사이에 유의적 차이를 나타내었다.

This study analyzes the chemical composition and thiobarbituric acid reactive substance levels of Godulbaegi (Youngia sonchifolia M.) depending on collection time. The moisture and crude fat content in leaf and root decreased, while crude fiber, crude protein, carbohydrate, and ash increased with increases in collection time. The mineral elements tended to increase in each sample with increases in collection time. The content of vitamin B increased as collection time increased. Vitamin C content was approximately five times higher in the leaves than that in the roots. Total amino acids in leaf and root increased considerably as collection time increased content of phenolic compounds in root were higher than that in the leaf and these contents increased. Antioxidant activity of Godulbaegi was higher in the root than in the leaf and increased as collection time increased.
