  • Aerobic plate counts(APC) gram-negative bacterial counts (GNC) and sensory evaluations on chic-ken carcasses during retail and refrigerated storages (3$\pm$1$^{\circ}C$ and 1$0^{\circ}C$) were evaluated. APC and GNC on whole chicken in retail store after storage of 7 days at 3$\pm$1$^{\circ}C$ increased to 3.11 and 3.89 log units com-pared to the initial controls. APC and GNC on whole chicken after storage of 7 days at 1$0^{\circ}C$ increased to 5.43 and 5.03 log units. Sensory scores of chicken carcasses obtained from retail store were in the "liked less" category after storage of 7 days compared to fresh controls. These results indicated that chicken carcasses during refrigerated (1$0^{\circ}C$) storages rapidly allowed the growth of aerobic spoilage bacteria dur-ing storage period which cluld not be microbiologically acceptable after of 7 days of 7 days.

  • Microbiological and sensory evaluations of refrigerated chicken (average weight of 500g) legs treated with acetic acid (AA), lactic acid (LA), or citric acid (CA) during between June and August, 1998 were assessed. Chicken legs were immersed in solutions containing 1% individual acids for 10 min. Chicken legs treated with AA for 10 min during storage of 16 days at 4$^{\circ}C$ had a significantly (P<0.05) lower levels of aerobic plate counts (APC) and gram-negative bacterial counts (APC) compared to those of LA or CA. AA had greater antimicrobial activity than LA or CA. Microbiological shelf-life of refrigerated chicken legs treated with AA increased eight-additional days compared to the controls. Sensory scores of chicken legs treated with acidulant were in the “liked less”to typical category during storage of days at 4$^{\circ}C$

  • This study was carried out to investigate the effects of packaging methods on the shelf-life of refrigerated chicken parts at $4^{\circ}C$. The microbial and physicochemical changes of chicken parts during storage periods were also examined to determine the shelf-life. The shelf-life of chicken parts dipped in 7.5% potassium sorbate with different packaging methods such as conventional packaging, vacuum packaging and modified atmosphere packaging was determined. The shelf-life of conventional packaged chicken parts dipped in 7.5% potassium was $19\pm3$ days and the shelf-life of vacuum packaged chicken parts dipped in 7.5% potassium sorbate was $30\pm5$ days. The shelf-life of 10% $CO_2$ and 90% $N_2$ gas contained packaged chicken parts dipped in 7.5% potassium sorbate was $26\pm4$ days while 20% $CO_2$ and 80% $N_2$ gas contained packaged chicken parts dipped in 7.5% potassium sorbate was $30\pm5$ days.

  • Microbiological and sensory evaluations of chicken wings treated with acetic acid and trisodium phosphate(TSP) during retail(1${\pm}$2$^{\circ}C$) and refrigerated storage(4$^{\circ}C$). Chicken wings(average weight of 15${\pm}$2g per leg) were treated with 0.5∼2% aerobic plate counts(APC) on the surface of chicken wings for storage of 16 days at 4$^{\circ}C$. During storage of 12 days at retail store(1${\pm}$2$^{\circ}C$), the treating chicken wings with 7.5∼10% TSP solutions for 10 min showed significantly inhibitory effect in preventing the growth of aerobic microbes. For odor and appearance scores, chicken wings treated with 0.5∼2% acetic solutions resembled untreated wings for storage of 16 days at 4$^{\circ}C$. However, both odor and appearance scores of chicken wings treated with 2.5∼10% TSP solutions were similar to those of untreated wings for storage of 4 days, and a higher in the storage of beyond 8 to 12 days at retail store.

  • Objective: Effect of addition of wheat bran (WB) and dried carrot pomace (DCP) on sensory, textural, colour, physico-chemical and nutritional characteristics of chicken sausage were evaluated. Methods: WB and DCP were used as a source of dietary fibre at 3%, 6%, and 9% level individually. Different quality attributes of sausages were estimated. One product from each source with very good sensory acceptability was selected to analyze dietary fibre content and shelf life under refrigerated storage. Results: Sensory acceptability of 3% fibre enriched sausage was comparable with control and a further increase in fibre level resulted in a decrease in sensory acceptability. Fibre enriched sausages were significantly harder and less cohesive than control sausage. Significant increase in gumminess and chewiness was observed at 6% level in WB treated sausages and 9% level in DCP treated sausages. Moisture content decreased significantly in all treated sausages, protein content decreased significantly in DCP-2 and DCP-3 sausages while fat content decreased in all WB and DCP-3 treated sausages in comparison to control. The fibre enriched sausage had significantly higher dietary fibre and lower cholesterol content. Cooking yield and emulsion stability increased in treated sausages and a significant difference was noticed at 6% level in both types of sausages. pH of WB treated sausages was significantly higher and DCP treated sausage significantly lower in comparison to control. Conclusion: The results of present study indicate that fibre enriched chicken sausage with moderate acceptability can be developed by incorporating WB and DCP each up to 9% level. Chicken sausage with very good acceptability, higher dietary fibre content and storability up to 15 days at refrigerated temperature can be developed by incorporating WB and DCP at 6% level each.

  • This study was performed to investigate the changes in meat quality characteristics of the sous vide cooked chicken breast during refrigerated storage at 4℃ for 14 d between before and after sous-vide cooking. Cooking loss and shear force were significantly increased, whereas expressible drip was significantly decreased along with reduction in the water holding capacity in both of two groups. Redness of meat juice was significantly (p<0.05) increased during storage, and considerably increased in the refrigerated samples after sous-vide cooked at the 7 to 10 d. The thiobarbituric acid reactive substances (TBARS) was significantly increased and was higher in the refrigerator stored chicken breast samples after sous-vide cooking. The volatile basic nitrogen (VBN) value was significantly increased in both groups, but the VBN value of the stored raw meat sample before sous-vide cooking was increased at an early storage, while the VBN value of the stored sample after sous-vide cooking was increased gradually in this study. Total viable counts and coliform counts were significantly decreased during storage, and coliforms were not detected after 7 d of storage in both groups. Salmonella spp. was not detected during the whole studied period. The outcome of this research can provide preliminary data that could be used to apply for further study of chicken breast using sous-vide cooking method that could be attractive to consumers.

  • This study was aimed at comparing the pH, color, thiobarbituric acid (TBA), volatile basic nitrogen (VBN), textural properties, and sensory evaluations of chicken meat patties containing lotus (Nelumbo nucifera) leaf powder, and assessing their shelf-life at refrigeration temperature ($4{\pm}1^{\circ}C$). In the refrigerated storage, the pH, lightness, yellowness, springiness values, and sensory properties scores of the control as well as all the treated samples decreased as the storage increased. The hardness, gumminess, chewiness, TBA, and VBN-values of control and all the samples treated with lotus leaf increased during refrigerated storage. At the end of the storage period (day 28), chicken patties containing lotus leaf powder had lower pH, redness, yellowness, TBA, VBN, hardness, gumminess, and chewiness values than those of control. The results of this study showed that a lotus leaf powder can increase storage stability in chicken meat products.

  • The objective of this study was to evaluate the effects of ingredients on the change of Samgyetang quality during refrigerated storage. The Samgyetang was prepared with five treatments. The five treatments were chicken cooked alone (Tl), cooked with jujubi, ginseng and garlic (T2), cooked with jujubi (T3), cooked with ginseng (T4) and cooked with garlic (T5). The TBA values of the Samgyetang over 4 days of refrigerated storage were T1(0.89) > T3(0.74) T5(0.74) > T4(0.57) > T2(0.42). The total plate counts of the Samgyetang in the T2 and T3 treatments were lower than with the other treatments. The coliform counts of the Samgyetang in the T2 and T5 treatments were lower than with the other treatments. The results from this study showed that ginseng had an antioxidant activity, jujubi lowered the total plate count and garlic lowered the coliform count in refrigerated Samgyetang. Therefore, the addition of these ingredients maintains the quality of Samgyetang during refrigerated storage.

  • This study was conducted to observe the association between antioxidant enzyme activity, free iron content and lipid oxidation of Korean native chicken (KNC) meat during refrigerated storage. Four lines of KNC (Yeonsan ogye, Hyunin black, Hoengseong yakdak and Hwangbong) were raised under similar conditions. A total of 16 roosters were randomly sampled and slaughtered at the age of 12 mon. The breast and thigh meats were stored aerobically for 10 d at 4℃. Although thigh meat had higher antioxidant enzyme activity, it was more susceptible to lipid oxidation and released more iron during storage than breast meat. Aerobic refrigerated storage for 10 d significantly decreased the activity of antioxidant enzymes and increased the amount of free iron and malondialdehyde. The activities of superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px) were negatively correlated with lipid oxidation, whereas that of catalase was not. The amount of free iron was positively associated with lipid oxidation. We concluded that chicken line did not affect strongly on antioxidant enzyme activity and lipid oxidation in breast meat of KNC. However, the thigh meat of Hwangbong and Hyunin black had higher SOD and GSH-Px activity, respectively, and lower malondialdehyde contents than that of other chickens. SOD, GSH-Px and free iron play significant roles in meat lipid oxidation during refrigerated storage.
