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.

Optimum preparation conditions for chicken head soup base were determined in terms of the effects of amount of chicken head and cooking time using response surface methodology based on sensory properties. Sensory properties that were evaluated were yellowness, turbidity, bloody, chicken-brothy, organ meat-like, and fat-like flavor. All values of sensory characteristics increased remarkably with an increase in the amount of chicken head and cooking time. The optimum amount of chicken head and cooking time were determined to be 1800 g and 150 minutes, respectively. Chicken head soup base had less fat, free amino acids, nucleotides, and its derivatives, but had significantly more cholesterol, sodium, and iron than whole chicken soup base. In flavor compound analysis, the amount of hexanal of the chicken head soup base, which is related to fat rancidity flavor, was 11-fold higher than that of the whole chicken soup base.

The purpose of this study was to determine the optimum amounts of vegetables to use for flavoring chicken head soup base. The effects of the amounts of ginger and onion on the sensory properties of chicken head soup base were examined, and the optimum amounts were determined using response surface methodology. Sensory properties that were evaluated were yellowness, turbidity, bloody flavor, chicken-brothiness, organ meat-like flavor, and sweet taste. The increased amounts of ginger and onion led to a decrease in bloody flavor and organ meat-like flavor. The optimum levels of ginger and onion were determined to be 40g and 50g, respectively. Chicken head soup base prepared with optimum amounts of vegetables contained more arginine, tryptophan, inosine monophosphate (IMP), and hypoxanthine than plain chicken head soup base. It also had less hexanal, which is related to fat rancidity.

This study has been designed to stress the thoughts that soups should be offered taking into account customer's preference aimed at leading to eventual customer's satisfaction and the importance that Korean traditional food should take the lead in shifting dining-out industry's paradigm to customer-orientation instead of product-orientation. From August 15 through August 30, 2003, the drawn-up questionnaires were handed out to 500 numbers of adults aged over 20 living in Seoul, metropolitan city of Korea and the finally collected 361 questionnaires from them have been analysed as a subject for this study. It showed that the male respondents(44%) dined out much more frequently than the female respondents(35%) and their rate of 5,000-7,000 Won for a meal was most preferred as their average expenditure at one sitting in the restaurant. When eating Korean food at home or in a restaurant, the majority(5l,3%) of them think the soups(Tang) should be served coupled with their ordered meals. Among soups using flesh and meat as a staple material, they most preferred beef & bone soup(33.2%), followed by beep rib soup(30.4%) and beef soup with seasoned red pepper(l0.8%), and among soups using fish & shell and crustacean as a staple material, most preferred were hot fish soup(20.6%), loach soup(l5.2%) and hot crab soup(11.4%). Among soups using beans as a staple material, they most preferred soybean paste stew(33.2%), uncurdled soybean curd stew(29.4%) and Dambuk stew(l5.8%). Among soups using fowls and birds as a staple material, chicken soup with ginseng(51.9%), plain chicken soup(l8.4%) and chicken soup with red pepper sauce(l2.3%) falls on the most preferred. Among soups using vegetables and seaweeds as a staple material, most preferred are sea mustard soup(25.3%), Kimchi soup(16.8%), soybean paste soup with Chinese cabbage(13.0%) and bean sprout soup(10.1%). The soups(Tang) most preferred in the morning time are those soups whose staple materials are vegetables and seaweeds, such as sea mustard soup, bean sprout soup, Kimchi soup and soybean paste soup with Chinese cabbage while the soups most preferred for the lunch time are beef & bone soup, beep rib soup, chicken soup with ginseng and beef soup with seasoned red pepper while beef soup with seasoned red pepper, beef & bone soup, soybean curd stew and Kimchi soup are most preferred soups for the dinner time. The survey showed that 41 % of the subject preferred chicken soup with ginseng for a food considered good by themselves for their health. The male respondents preferred Bosin-tang(soup of edible-dog meat) than the female counterparts did, while the female respondents preferred chicken soup with ginseng than the male counterparts did. The survey showed that when eating korean traditional food, 70% of the subject are visiting a restaurant where soups are cooked delicious while 61% of the subject think that price does not matter if only food tastes good, which is reflecting that taste of food is a decisive factor in selecting menu rather than its price is. In conclusion, you can say that taste of soup is the most important factor creating steady customer in the restaurant, taking it into account Korean people most prefer their traditional food when dining out.

The current mandatory domestic biodiesel blending ratio is 3.5%, which is planned to be gradually increased to achieve carbon neutrality by 2050. The aim of this study was to improve domestic self-sufficiency in biodiesel raw oil by conducting a technical review on the possibility of utilizing waste oils, such as soup oil, chicken oil, and leather oil, as biodiesel feedstocks. These waste oils have an acid value that is too high to be converted directly into biodiesel. Therefore, a pretreatment to reduce the acid value is necessary. The neutralization process was examined as a potential technology for reducing the acid value. The oil recovery rate of the soup oil after neutralization was significantly low at 37.6 wt%. The oil recovery rates of leather oil and chicken oil were 66.49 wt% and 79.08 wt%, respectively. Based on biodiesel conversion experiment using waste oil with a reduced acid value, the conversions were analyzed as 89 wt%, 91.1 wt%, and 90.5 wt% for soup oil, leather oil, and chicken oil, respectively. Thus, it is technically possible to use soup oil, leather oil, and chicken oil as raw materials for producing biodiesel.

Sodium chloride (NaCl) replacement with calcium chloride (CaCl₂) effect on protein solubility, proteolytic enzyme and quality characteristics of a chicken soup prepared from spent hen (SH) chicken were investigated. By means of immerse marination prior to cooking, a total of 60 skinless SH breast meat were randomly allocated into ten groups admitted to treatments with marinade solution containing sodium tripolyphosphate (STPP) and reduced percentage of NaCl with CaCl₂ at 0%, 25%, 50%, 75%, and 100% at 4±2℃ for 20 h. STPP was adjusted to 0.5% for all treatments and NaCl replacement at 0% was used as control. The different methods, particularly boiling at 100℃ and retorting at 121℃, 1.5 kgf/cm² for 60 minutes, were applied following marination. An upregulation of cathepsin-B and caspase-3 enzymes were a consequences from a higher percentage of CaCl₂ within meat environment. Accordingly, modified the protein solubility in particular the myofibrillar and total protein solubility. In addition, a significant increase in water holding capacity (WHC), pH value, myofibril fragmentation index (MFI), and moisture content was obtained due to salt replacement (p<0.05). Limited effect was observed for shear force value, collagen content and cooking yield. Eventually, this study implied that although protelytic enzyme and protein solubility was upregulated by the replacement of NaCl with CaCl₂ at >75%, extensive effect on texture properties was not observed. Therefore, NaCl replacement at 75% could be a promising strategy for quality improvement of SH chicken soup.
