  • Rabbit meat has high nutritional and dietetic characteristics, but its consumption rate is comparatively lower than other meat types. The nutritional profile of rabbit meat, by comparison with beef, pork, and poultry, is attributed to relatively higher proportions of n-3 fatty acids and low amounts of intramuscular fat, cholesterol, and sodium, indicating its consumption may provide health benefits to consumers. But, the quality attributes of rabbit meat can be originated from different factors such as genetics, environment, diet, rearing system, pre-, peri-, and post-slaughter conditions, and others. Different rabbit breeds and the anatomical location of muscles may also affect the nutritional profile and physicochemical properties of rabbit meat. However, adequate information about the effect of those two factors on rabbit meat is limited. Therefore, cumulative information on nutritional composition and carcass and meat quality attributes of rabbit meat in terms of different breeds and muscle types and associated factors is more important for the production and processing of rabbits. Moreover, some studies reported that rabbit meat proteins exhibited angiotensin-converting enzyme inhibitory characteristics and antioxidant properties. The aim of this review is to elucidate the determinants of rabbit meat quality of different breeds and its influencing factors. In addition, the proven biological activities of rabbit meat are introduced to ensure consumer satisfaction.

  • Objective: The objective of this study was to evaluate the effect of biogas slurry application on biomass production and the silage quality of corn. Methods: A field experiment was conducted in which corn was grown using different biogas slurry application rates. The effect of 25% to 500% biogas slurry nitrogen replacement (T1 to T14) on the yield and quality indices of corn were studied by field plot experiments. Results: The results revealed that biogas slurry application improved the stem diameter and relative feed value of corn silage in treatments T13 and T11. Moreover, the fermentation quality of corn silage was improved due to an increase in lactic acid content; in comparison with the chemical synthetic fertilizer (CF) group. The crude protein contents of corn silage had no obvious change with increasing biogas slurry application. However, the forage quality index of acid detergent fiber was decreased (p<0.05) in the T11 group compared with the CF group. In addition, higher (p<0.05) 30 h in vitro dry matter digestibility and 30 h in vitro neutral detergent fiber digestibility were observed in the T11 and T13 groups than in the CF group. Conclusion: Based on these results, it was concluded that the optimum biogas slurry application rate for corn was approximately 350% to 450% biogas slurry nitrogen replacement under the present experimental conditions.

  • Objectives: The purpose of this study is to evaluate the quality of case reports published in the Journal of Korean Obstetrics and Gynecology from April 2019 to February 2024, compared with January 2015 to March 2019. Methods: Case reports were selected by searching from archive on the website of society of the Journal of Korean Obstetrics and Gynecology. The quality of the case reports were assessed based on CAse REport (CARE) guideline. Results: A total of 30 case reports was finally included for the assessment. Overall quality of reporting for case reports published from April 2019 to February 2024 was improved compared to one of previous study. However, the 4 items of CARE guidelines with an unreported rate of 50% or more - patient's perspective on interventions (96.67%), diagnostic challenges (93.33%), intervention adherence and tolerability (93.33%), adverse events (56.67%) - are items that require active description in future case reports. In addition, Keyword and timeline have more than 50% reported to be 'Not-sufficient' in both previous and present studies. So active efforts by researchers are needed to include 'Case report (or Case study)' in keywords, and to include intervention by period, symptom changes in a timeline. Conclusions: Despite the overall improvement in the quality of reporting in the Journal of Korean Obstetrics and Gynecology, efforts to improve the quality of case reports should be continued.

  • The principal objective of this study was to develop a processed food using aged garlic. Pound cake samples were prepared with semi-solid aged garlic at levels of 0, 5, 10 and 15% ($25^{\circ}C$, 7 days). The pH of the batter prepared with the aged garlic ranged between 6.79 and 7.01 and the control pH was 7.21. The specific loaf volume of the pound cake prepared with the addition of 5~15% aged garlic decreased, from 2.78 to 2.51 cm3/g. The baking loss rate of the pound cake prepared with 0~15% added aged garlic also decreased by 6.91~6.42%. The lightness, redness, and yellowness values of the pound cake decreased with increases in the percentage of aged garlic. The adhesiveness, gumminess, and chewiness of the samples did not differ significantly with differing amounts of added aged garlic. DPPH (2,2-diphenyl-1-picrylhydrazyl) radical scavenging activity, however, was improved significantly via the addition of aged garlic. In the sensory evaluations, the pound cake prepared with 10% added aged garlic received higher acceptance scores for the properties of smell, taste, softness, moistness, adhesiveness and overall acceptability. Consequently, the optimal quality achieved in this set of experiments was with a pound cake to which 10% aged garlic had been added.

  • This study was conducted to investigate the effects of adding gochujang addition to cookie dough on the quality characteristics of cookies. Cookies were prepared by replacing 0% 5%, 10%, 15% and 20% flour with gochujang. The gochujang pH, total soluble solid and salinity were $4.84{\pm}0.02$, $63.33{\pm}4.19%$ and $7.63{\pm}009%$, respectively. The moisture content in gochujang was $40.10{\pm}0.10%$, and the color values of gochujang was were as L-value $24.46{\pm}0.06$, a-value $10.18{\pm}0.13$, and b-value $7.44{\pm}0.10$. The pH values of cookies decreased according to the addition of gochujang. The values of density and loss rate in cookies were not-significantly different among the samples. Spread factor and moisture content of cookies increased with amounts of added gochujang. The salinity and total soluble solid content of cookies with gochujang were significantly higher than those of the control. L-value was significantly reduced, and a-value and b-value increased by adding gochujang. Total phenolic content and DPPH free radical scavenging activities were increased according to the amount of gochujang. For sensory evaluation, gochujang added cookies were more preferred in terms of color, softness and overall preference. Overall, these results indicate that adding 10% gochujang is desirable for making gochujang cookies.

  • This study aims to investigate the quality characteristics of breads with the addition of sweet pumpkin powder. Farinogram showed that the absorption rate of the dough decreased, the development time and stability became shortened, and the degree of attenuation tended to be grown along with increasing the amount of pumpkin powder. From the amylogram, it was found that the gelatinization starting temperature and the maximum viscosity of pumpkin powder added dough seemed to be decreased as the amount of pumpkin powder was increased. Extensogram showed that there was a decrease in the degree of extension of the dough added with increasing the amount of pumpkin powder, while an increase in the degree of resistance and resistance/extensibility. The lightness (L value) and redness (a value) of bread was found to be decreased with increasing the amount of pumpkin powder, while the yellowness (b value) increased. In terms of the dough texture, for which the hardness, cohesiveness and gumminess of the dough were measured, there were no significant differences between groups, while the dough added with 8.0% pumpkin powder showed a significant decrease in the elasticity. The results of sensory evaluation showed that the highest score of color (p<0.05) and taste (p<0.05) were obtained from the bread added with 6.0% and 8.0% pumpkin powder, while the highest score of texture in control and 3.0% pumpkin bread. In addition, the highest score of flavor (p<0.05) and overall acceptance (p<0.05) were observed in bread added with 6.0% pumpkin powder. Upon the results of this study, it was assumed that the development of food products using pumpkin are prospective in response to health-oriented consumers.

  • The purpose of this study was to examine the qualities of muffins with 0, 3, 6, 9, and 12% bitter melon powder. The specific gravity of muffins prepared by adding bitter melon powder was higher than that of the control group. The height of the control group was higher than that of the samples with bitter melon powder. The weight of muffins was not significantly different between all sample groups. The volume and specific loaf volume of muffins were decreased by the addition of bitter melon powder. The baking loss rate of muffins was not significantly different between all sample groups. The moisture content of the samples with bitter melon powder was higher but the pH of muffins was lower than those of the control group. DPPH radical scavenging activity of the control group was 26.86%, whereas the samples with bitter melon powder ranged from 41.35~74.91%. In crumb color, the L value was decreased, but a and b value were increased significantly by the addition of bitter melon powder. The hardness, springiness, cohesiveness, chewiness and brittleness of textural properties of muffins were significantly decreased by the addition of bitter melon powder. Sensory evaluation scores in terms of appearance, flavor, taste, texture and overall preference of groups with 3% and 6% of bitter melon powder did not show any significant difference when compared to the control group. Based on the above results, using less than 6% of the bitter melon powder would be proper to make muffins.

  • Physicochemical and sensory characteristics of pound cake prepared with various levels of Angelica gigas Nakai powder were investigated. The pH of batter prepared with Angelica gigas Nakai powder ranged between 7.17 and 7.30 and that of the control was 7.34. The moisture content and pH of pound cakes was found to decrease with increasing Angelica gigas Nakai powder content. The specific volume of the control cake was 1.793 ml/g, that of pound cakes prepared with Angelica gigas Nakai powder was 1.806~2.026 ml/g. The baking loss rate of the control was 11.33% and that of pound cakes prepared by adding Angelica gigas Nakai powder was 10.29~6.66%. DPPH radical scavenging activity of the control group was 23.58%, whereas pound cakes prepared by adding Angelica gigas Nakai powder ranged from 38.77~77.60%. The a value of redness was increased, but L and b value were decreased significantly by the addition of Angelica gigas Nakai powder. The hardness and brittleness of the pound cakes were increased significantly by the addition of Angelica gigas Nakai powder. Sensory evaluation scores in terms of flavor, taste and overall preference for pound cakes were higher for the 2% substituted sample group than for any of the others. The results of this study suggest that the addition of 2% Angelica gigas Nakai powder was the best substitution ratio for pound cake.
