  • This study was tested the effects of the addition of blended wasabi juice on the quality characteristics of the soy sauce seasoned chicken meat at $4^{\circ}C$ for 12 days. The proximate analysis on the blended wasabi juice (w/w) showed 76.55% water, 4.15% crude protein, 0.58% crude fat, and 1.31% ash. There was no significant differences in the pH of the samples. The lightness ($L^*$) and yellowness ($b^*$) increased in proportion to the increased amount of the blended wasabi juice, but the redness ($a^*$) tended to decrease. The volatile basic nitrogen (VBN) was lower with the increased addition of the blended wasabi juice. The level tendencies in the salinity and water-soluble solids decreased with increasing amount of the blended wasabi juice added, but the difference was not significant. The total counts of viable cells and coliforms were lower in the juice-treated groups. In the preference test of the samples, the seasoned chicken breast with 2% blended wasabi juice was the most preferred in the overall acceptability, color, saltiness, sweetness, flavor, and texture.

  • This study was conducted to compare growth performance, carcass characteristics and meat quality of 4 breeds of local chicken. A total of 480 1-d-old chicks were distributed to 16 pens, with 4 treatments of breed, 4 replicates and 30 chicks per pen. Three Korean local breeds of white-mini broiler, Hanhyup-3-ho, and Woorimatdag, and a breed of silky fowl were raised under identical rearing and feeding conditions for 31-d, 37-d, 36-d, and 59-d, respectively. The BW and feed consumption on a pen basis were weekly measured for all pens, and ADFI, ADG and gain:feed were calculated for each pen. The ADFI and ADG of 3 breeds of Korean local chicken were greater than those of silky fowl (p<0.05). Within the Korean local breeds, ADFI of white-mini broiler was the highest (p<0.05), and ADG of Hanhyup-3-ho and white-mini broiler was the highest (p<0.05). Gain:feed of silky fowl was less than that of the 3 breeds of Korean local chicken. The carcass and breast yield of white-mini broiler were the greater than those of other breeds (p<0.05). The breast meat color (CIE $L^*$, $a^*$, and $b^*$) of 3 breeds of Korean local chicken were higher than that of silky fowl (p<0.05). The breast meat of Hanhyup-3-ho had greater cooking loss (p<0.05), whereas water holding capacity and pH were less than those of other breeds (p<0.05). The color score of 3 breeds of Korean local chicken was higher than that of silky fowl (p<0.05). Woorimatdag had a higher score on tenderness (p<0.05), whereas flavor score was less than that of other breeds (p<0.05). In conclusion, 4 local breeds of chicken have some unique features and seem to have more advantages, and this information can help consumers who prefer healthy and premium chicken meat.

  • The objective of this study was to compare the quality characteristics of chicken breast and thigh meat from North Korean native chickens (NKNC), South Korean native chickens (SKNC, woorimotdak), and commercial broilers (CB). NKNC thigh meat had a higher crude protein content than CB. In addition, the breasts of NKNC and CB had higher pH values than that of SKNC, but the cooking loss was higher in NKNC. The surface color of the breast and thigh meat of NKNC was darker and redder than that of SKNC and CB. The total collagen content of the breast and thigh muscles was the highest in NKNC, followed by SKNC and CB. A similar trend occurred with breast meat hardness. The content of arachidonic and docosahexaenoic acids was higher in both the breast and thigh muscles of NKNC than in those of the other groups, while the concentrations of linoleic and linolenic acids were higher only in thigh meat. Sensory evaluation did not show any differences among the three different strains of chicken except for the meat color. Sensory panelists preferred thigh meat from SKNC and CB to that of NKNC due to the strong dark color of the NKNC. Based on these results, NKNC had harder breasts based on texture, as well as a darker surface color and higher composition of long chain polyunsaturated fatty acids than CB. The quality characteristics of SKNC tested in this study were intermediate between NKNC and CB; however, SKNC may have a better chance of acceptance by Korean consumers due to the undesirable color of NKNC.

  • Objective: The aim of this study was to compare the quality characteristics of retorted Samgyetang (Korean ginseng chicken soup) made from white semi-broilers (WSB; Ross×Hyline white, 3 weeks old), commercial broilers (CB; Ross, 4 weeks old), Korean native chickens (KNC; Hanhyup-3-ho, 12 weeks old) and old laying hens (OLH; Hyline white, 72 weeks old) and to explore the possibility of using the carcasses of KNCs and OLHs as raw material for product diversification. Methods: Raw and cooked meat quality, fatty acid composition and consumer acceptance were analyzed. Results: Among the chicken breeds, OLH and KNC showed a higher shear force value than WSB and CB due to high insoluble collagen contents. However, the meat of KNC was more tender than that of OLH. The meat of OLH was characterized by the lowest moisture content and highest crude fat content. The meat of KNC was characterized by a higher proportion of saturated fatty acids, α-linolenic acid and arachidonic acid than that of OLH. The meat of OLH showed the highest content of unsaturated fatty acid, particularly linoleic acid, in its thigh meat. Electronic nose readings revealed that the meat aroma pattern was clearly different across breeds. OLH had the lowest overall acceptance score, while no differences were found in flavor, texture, juiciness and appearance among WSB, CB, and KNC. Conclusion: KNC shows potential as raw material for Samgyetang, while additional preprocessing methods, such as tenderization and fat removal, are required for the utilization of OLH as raw material for retorted Samgyetang.

  • The effects of salt concentration and heating conditions on the thermal gelation properties of surimi produced from mechanically deboned chicken meat (MDCM) were investigated. Chicken surimi was manufactured by washing (MDCM: 0.5% NaCl=1:4), standing, straining and centrifuging. The fat, water-soluble protein and heme pigment in the MDCM were removed by increasing washing cycles. The compressive force of the chicken surimi increased as the concentration of salt was increased from 0% to 5%. Total gel strength of the surimi measured by texture profile analysis showed a maximum in the range 3-5% NaCl. Microstructural analysis showed that the unfolding network structure of the surimi gel began to appear at NaCl concentrations>2%. The optimum heating condition for gelation was $90^{\circ}C$ for 40 min as this resulted in maximum values for measures of gel strength including compressive force, hardness, fracturability, adhesiveness, springiness, gumminess, chewiness and resilience. Chicken surimi gel formed by cooking at a heating rate of $1^{\circ}C/min$ to $90^{\circ}C$ showed better a texture than gels produced at $1.85^{\circ}C/min$. Our result show that a lower rate of heating improves chicken surimi gelation.

  • The present study investigated the effects of Liriopeplatyphylla extract (LPE) and Akebiaquinata extract (AQE) on breast meat properties when used as dietary supplements of broiler chickens. First, the identification and quantification of phenolic acids and flavonoids were carried out by HPLC. As a result, the total amount of phenolic acids and flavonoids was higher in AQE than LPE. These extracts were added at a rate of 0.2% to the broiler diets, and a feeding trial was conducted in battery cages for 35 d. At the end of the experiment (d 35), six carcasses from each treatments were used for evaluating meat quality. The experimental results indicate that color shades, pH levels, volatile basic nitrogen, thiobarbituric acid reactive substance (TBARS), cooking loss and drip loss of breast meat fed with 2 extracts were not different as compared with the controls at d 0 and d 10 of storage. However, TBARS values of breast meat fed with either the control diet or the LPE supplementation was increased as the storage period increased (from d 0 to d 10) (p<0.05), while AQE-fed groups were not different between d 0 to d 10 of storage. In textural properties, the addition of LPE and AQE decreased shear force values at d 10 of storage (p<0.05). Cohesiveness, gumminess and chewiness of breast meat were increased in AQE-fed groups when compared with the control at d 0 of storage (p<0.05). Dietary additions of AQE and LPE only increased the linoleic acid contents of chicken breast meat (p<0.05). In conclusion, supplementation of these extracts in broiler diets may potentially influence meat qualities including the TBARS, textural properties and linoleic acid levels in broiler chicken meats.

  • The present study was carried out to evaluate the nutritional quality of rabbit meat protein. The composition of amino acids contained in rabbit meat was compared with those of other animal meats such as beef, pork and chicken. Also included in this study was the question whether the cooking and storage conditions affect the amino acid composition and the pepsindigestibility of rabbit meat protein. The results are summarized as follows: 1. The large variation observed from sample to sample of EAA (essential amino acid) composition in rabbit meat was found to be an interesting but peculiar property of rabbit meat protein. The most limiting amino acid of rabbit meat protein was phenylalanine, whereas methionine was the first limiting amino acid of both beef and pork proteins. Chemical scores of various meat proteins were 68, 65, 66, and 74 for rabbit meat, beef, pork, and chicken respectively. 2. In pan roasting, the EAA damaged most by heat was methionine (15%). When cooked after two months of frozen storage, lysine decreased most. 3. Higher pepsin digestibility was obtained by cooking rabbit meat after seasoned in alcohol, ginger juice, and other spices compared with various other cooking conditions without seasoning. The pepsin digestibility value was even higher for the seasoned meat than for the raw meat. 4. Among various meats tested the rabbit meat showed the lowest pepsin digestibility. 5. A simple measurement of released methionine could be used to determine relative digestibility instead of measuring $NH_2-N$ content after pepsin digestion. From all the results obtained in this study it can be concluded that rabbit meat is a good Protein food item when used fresh and stored properly to prevent rancidity problems. It is suggested to study further the peroxidation effect of unsaturated fatty acids on protein quality. This study was supported by the Ministry of Science and Technology in Korea.

  • The aim of this study is to determine the effects of using emulsion manufactured with soybeans (ES) to substitute chicken breast in Vienna sausages. Four types of Vienna sausages (S1: 10% ES and 50% chicken, S2: 20% ES and 40% chicken, S3: 30% ES and 30% chicken, and S4: 40% ES and 20% chicken) for this study were made. The pH, color, proximate composition, sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE), microphotographs, cooking yields, and texture profile analysis of sausages were examined. The pH value of uncooked and cooked sausages increased significantly with increasing ES content (p<0.05). The crude protein contents of S2, S3, and S4 were significantly higher than that of the control (p<0.05). Furthermore, the SDS-PAGE results showed that α-conglycinin, β-conglycinin, and the acidic subunit of glycinin all increased with increasing ES content. Microphotographs revealed that increasing the ES content decreased the size of fat globules. The cooking yields of samples increased significantly with increasing ES content (p<0.05). The hardness values of ES treated samples were significantly lower than that of the control (p<0.05). Therefore, 30% substitute of chicken breast with ES can improve the quality and structure of Vienna sausage, without inducing critical defects.

  • This study was conducted to investigate the effect of chicken skin and pork backfat on quality of Dakgalbi-taste chicken sausage as fat sources. The sausages were manufactured with 100% chicken breast without fat sources, 85% chicken breast meat with 15% chicken skin or 85% chicken breast meat with 15% pork backfat, respectively. Batters for production of chicken sausage were mixed with 5% Dakgalbi sauce and 4.92% ingredients (meat and lipid basis) for 20 min and then stuffed into casing. All cooked sausages were vacuum-packaged and stored at $4^{\circ}C$ for 14 days. Moisture and crude protein contents were higher in the control, and crude lipid content was higher in chicken sausage with pork backfat (p<0.05). Unsaturated fatty acids content and monounsaturated fatty acids/saturated fatty acids ratio of sausage with pork backfat were lower than those of control and sausage with chicken skin (p<0.05), which were influenced by fatty acids compositions of fat sources. The chicken sausage with pork backfat showed a lower hardness and chewiness, and higher springiness measured by food texture analyzer. The sausage with pork backfat had a high level of water holding capacity (WHC) during storage (p<0.05). In conclusion, Dakgalbi-taste chicken sausage containing chicken skin had higher unsaturated fatty acid compositions, but showed lower textural quality compared with that containing pork backfat.

  • We evaluated the effect of adding mechanically deboned chicken meat (MDCM) (0, 10, 20, 30 or 50%) on quality characteristics of chicken sausage. Adding MDCM decreased the protein content of chicken sausage, but ash content increased significantly. Adding MDCM had no effect on pH and water holding capacity of sausage. Adding MDCM increased cooking loss, but did not affect the shear force value of the sausage. Adding MDCM decreased the L- (lightness) and b- (yellowness) values but increased the a- (redness) value of sausage. Adding MDCM decreased the hardness and cohesiveness values, but did not affect the springiness value of chicken sausage. Adding MDCM decreased the juiciness and hardness but increased the flavor and chewiness scores of chicken sausage. Regardless of the MDCM addition level, all chicken sausage contained low residual nitrite ion (<4 ppm). During the 10 d of storage at $4^{\circ}C$, adding MDCM did not affect total microbial count or TBA values of chicken sausage, but the VBN value of the sausage increased slightly. However, all storage characteristic values in the sausage were within the safety range. Adding MDCM (0, 10 or 20%) to chicken sausage resulted in a finely structured protein matrix under scanning electron microscopy (SEM), which indicated a good meat emulsion, but adding MDCM at more than 20% resulted in a very coarse protein matrix structure.
