This study was performed to evaluate the quality characteristics of three deboned categories of chicken thigh meat: one which was slaughtered and deboned in the same plant (fresh); one which was slaughtered, deboned, frozen, and thawed in the same plant (frozen-thawed); and the last which was slaughtered in a plant, deboned in a different plant, but then transferred to the original plant (fresh-outside). Surface color, drip loss, 2-thiobarbituric acid reactive substances (TBARS) value, sensory evaluation, and total aerobic bacterial counts of the chicken samples were determined. Moreover, the torrymeter was used to measure the differences in freshness of the chicken meat. The surface color and the TBARS values did not show significant differences among the three categories. However, the total aerobic bacterial counts of fresh-outside and frozen-thawed chicken meat were significantly higher than the fresh chicken meat on the first storage day, and the drip loss of frozen-thawed chicken meat was significantly higher than the fresh-outside and fresh chicken meat. In addition, the sensory evaluation of frozen-thawed chicken meat was significantly lower than the fresh-outside and fresh chicken meat. Torrymeter values were higher in fresh chicken meat than fresh-outside and frozen-thawed chicken meat during the storage period. These results indicate that the quality of frozen-thawed chicken meat is comparatively lower than the fresh chicken meat, and the torrymeter values can accurately differentiate the fresh-outside and frozen-thawed chicken meat from the fresh ones.

This study investigated the influence of ultrasound treatment on the quality properties of chicken breast meat and the broth from Korean chicken soup (Baeksuk). In this study, the internal temperature, malondialdehyde content, textural profile, color, dry matter, protein content, phenolic content and sensory properties of chicken breast meat broth from chicken soup with ultrasound treatment were analyzed. The chicken, plants, salt, and water were vacuum packaged in a retort pouch. The chicken soup was manufactured with ultrasound treatment (45 kHz and $1.6W\;cm^{-2}$) in a water bath at $85^{\circ}C$. The texture properties, color, and lipid oxidation of the chicken breast meat from the chicken soup were not affected by the ultrasound treatment. There was no significant difference in the lipid oxidation in the broth of the chicken soup between the control and ultrasound treatment. The dry matter and crude protein contents of the broth were significantly increased by the ultrasound treatment. The broth flavor of the chicken soup manufactured with the ultrasound treatment received a higher score than that of the control in the sensory analysis. There were no differences in the sensory properties of the chicken breast meat from the chicken soup between the control and ultrasound treatment Therefore, the broth quality of the chicken soup can be improved by heating with ultrasound treatment. Additionally, to apply ultrasound technology to the production chicken breast meat and the broth from chicken soup, it is necessary to further study the quality characteristics of the breast meat and broth according to various frequencies and strengths.

Objective: The objective of this research was to study the electrical properties and quality of frozen-thawed chicken breast meat and to investigate the relationship between these parameters at different times of frozen storage. Methods: Thawed samples of chicken breast muscles were evaluated after being kept in frozen storage at $-18^{\circ}C$ for different periods of time (1, 2, 3, 4, 5, 6, 7, and 8 months). Results: The results showed that water-holding capacity (WHC) and protein solubility decreased while thiobarbituric acid-reactive substances content increased with increasing storage time. The impedance module of samples decreased during 8-month frozen storage. Pearson correlation coefficients showed that the impedance change ratio (Q value) was significantly (p<0.05) related to pH, color, WHC, lipid oxidation and protein solubility, indicating a good relationship between the electrical properties and qualities of frozen-thawed chicken breast meat. Conclusion: Impedance measurement has a potential to assess the quality of frozen chicken meat combining with quality indices.

The consumption of poultry meat (chicken and turkey) grew the most during the past few decades due to several contributing factors such as low price, product research and development, favorable meat characteristics, responsive to consumer needs, vertical integration and industry consolidation, new processing equipments and technology, and aggressive marketing. The major processing technologies developed and used in chicken processing include forming/restructuring, tumbling, curing, smoking, massaging, injection, marination, emulsifying, breading, battering, shredding, dicing, and individual quick freezing. These processing technologies were applied to various parts of chicken including whole carcass. Product developments using breast, thigh, and mechanically separated chicken meat greatly increased the utilization of poultry meat. Chicken breast became the symbol of healthy food, which made chicken meat as the most frequent menu items in restaurants. However, the use of and product development for dark meat, which includes thigh, drum, and chicken wings were rather limited due to comparatively high fat content in dark meat. Majority of chicken are currently sold as further processed ready-to-cook or ready-to-eat forms. Major quality issues in chicken meat include pink color problems in uncured cooked breast, lipid oxidation and off-flavor, tenderness PSE breast, and food safety. Research and development to ensure the safety and quality of raw and cooked chicken meat using new processing technologies will be the major issues in the future as they are now. Especially, the application of irradiation in raw and cooked chicken meat products will be increased dramatically within next 5 years. The market share of ready-to-eat cooked meat products will be increased. More portion controlled finished products, dark meat products, and organic and ethnic products with various packaging approaches will also be introduced.

This study was performed to evaluate the effects of chicken breast meat on the quality of mackerel sausages. The mackerel sausages were manufactured by additions of 5%, 7%, and 10% of chicken breast meat. The lightness of mackerel sausages showed no significant differences between the control and addition groups. The redness increased in a dose-dependent manner, but the yellowness decreased significantly with the addition of 7% chicken breast meat (p<0.05). The whiteness value of mackerel sausage added with 7% chicken breast meat was significantly higher than those of the other groups (p<0.05). In texture analysis, the hardness and adhesiveness of the mackerel sausage added with 5% of chicken breast meat showed no significant differences as compared to the control. However, the mackerel sausages added with 7% and 10% of chicken breast meat showed a dose-dependent decrease. The gel strength of the mackerel sausage added with 5% chicken breast meat was not significantly different from the control, but the addition of 7% and 10% chicken breast meat reduced the gel strength of the mackerel sausage. In sensory evaluation, the mackerel sausages prepared with chicken breast meat have higher scores in smell, taste, texture, hardness, chewiness, and overall preference as compared to the no addition group. Therefore, these results suggest that the optimal condition for improving the properties within mackerel sausages was 5% addition of chicken breast meat.

An experiment was carried out to determine the effect of cooling water treatment with ionized calcium on calcium content, extending the shelf-life and quality of fresh chicken meat in poultry slaughtering process. The subjects were divided into four groups: control (0% without ionized calcium) and treatment groups (0.5, 0.7, 0.9% ionized calcium). The results indicated that the cooling water treatment with ionized calcium exhibited the bacterial counts of $10^5CFU/cm^2$ in surface of chicken meat, and maintained the quality of fresh chicken meat with extending the shelf-life above seven days when compared with that of control group. The results found that the cooling water treatment with ionized calcium could produce the calcium enrichment of chicken meat as nine times higher in calcium content of chicken meat when compared with that of control group. pH, water holding capacity, TBARS (MDA mg/kg) in chicken meat via the cooling water treatment with ionized calcium showed 6.4, above 50, below 0.10, respectively, with preventing the oxidation of unsaturated fatty acids. Lightness ($L^*$) as a chicken meat color, shear force indicated above 60, below $1.70kg/0.5inch^2$, respectively.

Chicken meat is a low-fat and high-protein food and consumption of chicken meat has been increasing globally. Various food ingredients are widely added for their specific purpose to processed chicken meat. Nonetheless, concerns about the association between high sodium intake and various diseases as well as negative perceptions of artificial additives are increasing. Therefore, in meat products, it is necessary to reduce the amount of salt and to replace artificial additives with natural ingredients. Our aim was to investigate the quality characteristics of low-salt chicken sausages manufactured with the addition of a winter mushroom powder. Sausages was manufactured with sodium pyrophosphate (0.3%) or winter mushroom powder (0%, 0.5% and 1.0%) to ground chicken breast. As a result of addition of the winter mushroom powder to low-salt chicken sausages, pH of the meat batter increased, and the proportion of jelly and melted fat exuded from sausages was reduced. The texture of sausages was softened and lipid oxidation in sausages was inhibited by the winter mushroom powder. This powder did not negatively affect the color and sensory properties of the sausages. According to the results of this study, the winter mushroom powder can serve as a natural ingredient to improve quality of low-salt chicken sausages.
