  • This study was conducted to investigate the effect of the lipid and collagen content and drip volume on the hardness of fish meat. Red sea bream (cultured and wild) and flounder (cultured, cultured with obosan and wild) were used for this study. Textural differences between cultured and wild meats were determined by the measurements of hardness, lipid and collagen content, and drip volume. Lipid content of the dorsal muscle was higher especially in cultured red sea bream (3.32%) than in wild one. Cultured and wild flounder contained lower content of lipid than red sea bream. The content of collagen was higher in cultured flounder fed with obosan (8.37 mg/g muscle) and wild flounder (8.02 mg/g muscle) than others. Drip volume was the highest in cultured flounder fed with obosan (8.67%). The hardness of raw meat was correlated with the contents of lipid (r= -0.7063) and collagen (r= 0.8307), significantly. Cultured fish contained more lipid and less collagen than wild one. So, the hardness of these fish meats was lower than wild one. However, cultured flounder fed with obosan showed no difference in hardness compared with wild one. In the cooked meat, there was no relationship between the hardness of fish meat and the contents of lipid and collagen. But, the drip volume was significantly related with the hardness (r= 0.6870). From these results, the factors contributing the textural difference between wild and cultured fish meat would be the lipid and collagen contents, and two ways to improve the texture of cultured fish meat could be suggested. One is to lower the lipid content by feed control, and the other is to raise the collagen content by inducing more fish movement.

  • Objective: Insulin resistance (IR) is an established risk factor for colorectal cancer (CRC). Given that CRC and IR physiologically overlap and the calpain-10 gene (CAPN10) is a candidate for IR, we explored the association between CAPN10 and CRC risk. Methods: Blood samples of 400 case-control pairs were genotyped, and the lifestyle and dietary habits of these pairs were recorded and collected. Unconditional logistic regression (LR) was used to assess the effects of CAPN10 SNP43 and SNP19, and environmental factors. Both generalized multifactor dimensionality reduction (GMDR) and the classification and regression tree (CART) were used to test gene-environment interactions for CRC risk. Results: The GA+AA genotype of SNP43 and the Del/Ins+Ins/Ins genotype of SNP19 were marginally related to CRC risk (GA+AA: OR = 1.35, 95% CI = 0.92-1.99; Del/Ins+Ins/Ins: OR = 1.31, 95% CI = 0.84-2.04). Notably, a high-order interaction was consistently identified by GMDR and CART analyses. In GMDR, the four-factor interaction model of SNP43, SNP19, red meat consumption, and smoked meat consumption was the best model, with a maximum cross-validation consistency of 10/10 and testing balance accuracy of 0.61 (P < 0.01). In LR, subjects with high red and smoked meat consumption and two risk genotypes had a 6.17-fold CRC risk (95% CI = 2.44-15.6) relative to that of subjects with low red and smoked meat consumption and null risk genotypes. In CART, individuals with high smoked and red meat consumption, SNP19 Del/Ins+Ins/Ins, and SNP43 GA+AA had higher CRC risk (OR = 4.56, 95%CI = 1.94-10.75) than those with low smoked and red meat consumption. Conclusions: Though the single loci of CAPN10 SNP43 and SNP19 are not enough to significantly increase the CRC susceptibility, the combination of SNP43, SNP19, red meat consumption, and smoked meat consumption is associated with elevated risk.

  • This study was conducted to evaluate the effects of dietary Korean red pine bark extract as an antibiotic replacements on cholesterol, fatty acids and the shelf-life of chicken meat. To accomplish this, chickens were fed the optimal level of red pine bark extract that was found to replace antibiotics in the diet of broilers. A total of 180 male broilers(Ross strain 308) were divided into three treated groups, T1(control group), T2(8 ppm of avilamycin) and T3(65 ppm of red pine bark extract per kg diet). The lipid content was reduced by 24.67% and 20.49% in T3 group, while the cholesterol level also decreased significantly in the T3 group by 20.49% and 20.55% when compared to the T1 and T2 groups, respectively. In addition, the saturated fatty acid level was lower in the T3 group than in the T1 and T2 groups, while the unsaturated fatty acid level of the T3 group was significantly higher than those of the other groups. The TBARS value of chicken thigh muscle containing its skin on the 7th day of low temperature storage was significantly lower by 23.86% and 21.17% in the T3 group than in the T1 and T2 groups, respectively. Evaluation of the color of the meat revealed that the $L^*$value (lightness) and $b^*$value(yellowness) were higher in the T3 group than in the T1 and the T2 groups, but that the pH was significantly lower in the T3. Based on the results of this study, the addition of 65 ppm red pine bark extract to the diet of broilers should improve their meat quality with respect to the lipid contents and shelf-life when compared to the addition of antibiotics.

  • This study was conducted to evaluate the effects of fermented red ginseng (FRG) on growth performance, apparent nutrient digestibility, blood hematology and meat quality in finishing pigs. A total of 96 ((Landrace${\times}$Yorkshire)${\times}$Duroc) pigs ($71.64{\pm}1.20\;kg$) were randomly allocated into one of the following dietary treatments: i) CON, basal diet; ii) FRG1, basal diet+1 g/kg fermented red ginseng; iii) FRG2, basal diet+2 g/kg fermented red ginseng and iv) FRG3 basal diet+4 g/kg fermented red ginseng. There were 6 replications per treatment with 4 pigs (2 gilts and 2 barrows) per pen. Throughout the whole period of the trial, there were no effects of FRG addition on ADG or G/F. Pigs fed FRG2 diet had lower ADFI (p<0.05) than those fed CON diet during 0-4 weeks while FRG2 and FRG3 treatments decreased ADFI (p<0.05) compared with CON treatment both during 5-8 weeks and the entire experiment. No differences were observed in apparent nutrient digestibility and blood hematology. However, FRG2 and FRG3 administration decreased the drip loss compared with CON (p<0.05). Pigs in FRG2 treatment had higher LMA (p<0.05) and lower WHC (p<0.05) than those in CON treatment. In conclusion, the supplementation of FRG had a minor effect on performance while partially improved meat quality in finishing pigs.

  • "Gyuhapchongseo" was published in 1809, and introduced the cooking method of the noble class in the late Joseon dynasty. The characteristics of the side dishes in "Gyuhapchongseo" are as follows. Firstly, red pepper was used as whole red pepper, shredded red pepper, powdered red pepper, or Korean hot pepper paste. Secondly, salt-fermented fish was used in some forms of Kimchi, including Sukbakgi, Dong A Sukbakgi, and Gyochimhae. Thirdly, to retain the juiciness of meat during roasting, meat was spread cold water on the surface, dipped into the washing water of rice or wrapped with wet paper. Fourth, to improve the visual effect of a dish, cooked foods were displayed with various color schemes, panfried foods with two tones (egg white and yellow) of color on each side and the use of radish pigmented with deep red color. On examination of the characteristics of food in "Gyuhapchongseo", I would suggest applicable practices for the present cuisine. The use of gravy produced from the boiling down of fish flesh could raise the nutritive value of Kimchi. In "Gyuhapchongseo", Yak po (semi-dried minced beef) is noted as being good for elderly people with bad teeth. A steamed dish with dog meat in Dong A in "Gyuhapchongseo" is made by hollowing out Dong A and putting a dog in it to cook the dog meat to well done in a fire made with the hulls of rice. This technique could be used to present cuisine for steamed and roasted dishes using food ingredients such as pumpkin, sweet pumpkin, and overripe cucumber.

  • 본 연구는 6개월령의 한우 36두를 이용하여 양질 조사료의 보충(Rice straw;RT, Rice straw +cubed roughage;RCT)과 황토의 첨가수준(0%, 1%, 2% 황토)이 생산성, 육질 및 경제적 효과에 미치는 영향을 규명하기 위하여 실시하였다. 실험기간 동안 볏짚에 양질 조사료의 보충(cubed roughage, RCT)은 볏짚단독 처리(RT)에 비하여 일당증체, 사료효율 및 출하체중에서 각각 10%, 6.8%, 8.2%로서 유의적으로 증가되었으나(P$<$0.05), 황토의 첨가는 한우의 성장성적에 뚜렷한 효과는 없는 것으로 나타났고, 2%의 첨가수준은 오히려 감소되는 경향을 보였다. 육질 및 경제성 분석에서는 RCT구는 뚜렷한 개선효과를 보였지만, RT구에서는 황토 1%에서만 첨가 효과가 있는 것으로 나타났다. RCT구에서는 1%, 2% 모두가 0%에 비하여 보다 개선된 결과를 나타내었다. 이와 같은 결과들은 한우 비육에 있어서 황토의 첨가는 성장성적에는 뚜렷한 효과가 나타나지 않았지만 육질과 경제적 효과에서는 1%의 첨가는 개선효과가 있는 것으로 사료되며, 고급육 생산을 위한 황토의 첨가시에는 양질의 조사료 보충이 경제적 효과성을 더욱 향상시킬 것으로 사료된다.

  • In this study, the alkiline water washing condition of mackerel(Scomber japonicus) dark meat was investigated to improve processing conditions of red muscle fish meat paste heating gel. Chemical alkaline water(CWM) and electrolytic alkiline water(EWM, pH 12) were used for washing the mackerel raw meat. Washed meats were minced with 2.5% salt and heated at $90^{\circ}C$/15 min to testing texture profile analysis. Moisture of CWM and EWM was increased with both washing times(p<0.05). Crude lipids and protiens were decreased with washing times. Lightness of chemical alkaline water washed mackerel heated paste gel(CWHPG) was higher than electrolytic alkaline water washed mackerel heated paste gel(EWHPG). Redness and yellowness were more decreased than control meats. Jelly strength of CWHPG and EWHPG was not increased more than 2 times wased meat and was increased with protein decrease. Texture profile analysis, max force1 of CWHPG and EWHPG was higher hardeness than the control meat except gel strains. From these results, it could be suggested that electric alkialine water washing is also effective in advance the red meat paste heating gel process of kamaboko industry.

  • This study examined the photostimulated luminescence (PSL) detection method suggested by the Korean Food and Drug Administration to assess whether the method can be used to identify irradiated spices in restructured pork patties, which served as a model system for processed meat products. Red and black pepper powders were irradiated at 0, 5.0, 7.5, and 10 kGy, and pork patties were formulated with the spice at irradiated pepper concentrations of 0.1% and 0.5%. PSL was then used to estimate amounts of light derived from the spice itself and pork patties. The results of PSL analysis showed that red and black pepper powders were determined as positive and presumptive positive, respectively, when irradiated at more than 7.5 kGy. However, when used in pork patties, all samples were negative for irradiation. Thus, PSL may not be useful in detecting irradiated ingredients used in processed meat products.

  • Lamb has long been considered a traditional meal within Australia; however as consumer preferences have changed since the 1950's, consumption of lamb has decreased from the 1980's. This is the result of changing societal roles, particularly for females, decreasing household sizes and increasing awareness of the impact of food choices on human health. Since the 1980's improvement of farm practices and increases in genetic gains has addressed part of this decline by increasing the amount of lean meat and decreasing fat in lamb retail cuts. Yet, this has created a challenge for the industry to utilise the larger carcases now being produced. Thus, a whole value chain approach to increasing consumption has been undertaken through several research programs to create cuts which suit the modern consumer, examine nutritional and eating quality and increase adoption of value added cuts. Therefore, this paper outlines this history of changing consumer patterns and the consequent research to address these changes.
