The purpose of this study was to investigate the meat metabolite profiles related differences in beef quality attributes (i.e., high-marbled and low-marbled groups) using nuclear magnetic resonance (NMR) spectroscopy. different marbling scores showed significant water content fat content. High-marbled had mainly higher taste compounds than meat. Metabolite analysis between two groups based on partial least square discriminant (PLS-DA). Metabolites identified by PLS-DA, such as...

Heat stress negatively affects cattle productivity by reducing feed intake. In the present study, we assessed if rumen microbiome composition of Hanwoo steers was altered exposure to heat stress. Rumen samples were collected from four that individually housed in climate-controlled chambers with 60% humidity and environmental temperatures of: 1) 15°C (0-day group), 2) 35°C for 3 days (3-day 3) 6 (6-day group). The total community DNA extracted, 997,843 bacterial 1,508,770 archaeal sequences...
Limited information is available regarding the use of microwave-dried Hermetia illucens larvae meal (HILM) as a dietary protein source for broiler diets. Therefore, we investigated effects HILM on carcass traits, meat quality, fatty acid (FA) profiles abdominal fat and meat, heavy metal residues in broilers. A total 126 male broilers were randomly assigned to three treatment groups (6 replicates 7 birds/pen): control diet two experimental diets which soybean was replaced with 25 or 50% HILM....
Neovascular eye diseases are a major cause of blindness. Excessive angiogenesis is feature several conditions, including wet age-related macular degeneration, proliferative diabetic retinopathy, and retinopathy prematurity. Development novel antiangiogenic small molecules for the treatment neovascular disease essential to provide new therapeutic leads these diseases. We have previously reported potential anti-angiogenic homoisoflavanone derivatives with efficacy in retinal choroidal...
This study evaluates how different feeding systems impact ruminal fermentation, methane production, and microbiota of Hanwoo steers native to Korea. In a replicated 2 × crossover design over 29 days per period, eight (507.1 ± 67.4 kg) were fed twice daily using separate (SF) system comprising concentrate mix forage or total mixed rations (TMR) in 15:85 ratio. The TMR-feeding group exhibited considerable neutral detergent fiber digestibility increase than the SF group. However, fermentation...

No significant fiber changes observed samples. In case Hunter's value, 'L' values...
Abstract The hand-held laser methane detector (LMD) technique has been suggested as an alternative method for measuring (CH4) emissions from enteric fermentation of ruminants in the field. This study aimed to establish a standard procedure using LMD assess CH4 production cattle and evaluate efficacy protocol detect differences fed with diets different forage-to-concentrate (FC) ratios. Experiment 1 was conducted four Hanwoo steers (584 ± 57.4 kg body weight [BW]) individually housed...
Bees are important pollinators in agriculture. The bee population has recently begun to decline possibly due pesticides. gut microbiota strongly influences the health of bees. bees is composed distinct members belonging selective taxa. Chemicals like pesticides can alter microbiota. present study investigated effect carbaryl on honey bees, which had come contact with rapeseed plants (Brassica napus) sprayed wettable powder during brood test under semi-field condition. Molecular techniques...

Alzheimer’s disease (AD) is a serious neurodegenerative brain that interferes with daily life. The accumulation of beta-amyloid (Aβ), along oxidative stress-inducing neurocellular apoptosis, has been considered one the causes AD. Thus, purpose this study to find natural products can reduce Aβ accumulation. ethanol extract Metasequoia glyptostroboides Hu & Cheng fruits (Cupressaceae) significantly reduced aggregation into oligomers and fibrils determined by Thioflavin T (ThT) assay....
The antioxidative effect and quality characteristics of different drying methods (hot air drying, far-infrared radiation vacuum freeze drying) from Schizandra Chinensis Baillon were investigated. moisture contents water activity(Aw) each 4.46% 0.38 values the lower than those other samples. A significant not difference in pH occurred all samples (p<0.05). highest content °brix was 6.60 °Brix respectively. turbidity hot 8.24 T%, far infrared 0.32 71.85 T%.

The objective of this study was to investigate the physicochemical properties Korean traditional soy sauces made with soybeans sown in different producing regions(Hadong, Paju) and seeding periods(late-May, mid-June, late-June). total acidity, salt content, chromaticity, browning, amino nitrogen content reducing sugar sauce samples were compared. It found that acidity level contents significantly lower mid-June soybeans, these increased as aged. Salt aging period regardless region...
본 연구에서는 국내산 특수용도 쌀품종 내 전분의 분자 및 결정 구조적 특성과 소화 특성을 분석하고 상관성을 살펴봄으로써 향후 쌀가공식품들을 개발하는 기초자료로 활용하고자 하였다. 백진주1호 전분은 다른 쌀품종에 비하여 아밀로스 함량, 아밀로펙틴의 분자량, A 사슬 (DP 6-12), 페이스팅 온도, 치반점도, SDS 함량은 유의적으로 낮았으며 B1 사슬(DP 13-24), 상대적 결정성, 호화온도(<TEX>$T_o$</TEX>, <TEX>$T_p$</TEX>, <TEX>$T_c$</TEX>), 호화 엔탈피(<TEX>${\Delta}H$</TEX>), 최고점도, 강하점도, RDS 함량이 높은 결과를 나타냈다. 소화율과 구조 이화학적 특성 간의 분석한 결과 SDS는 온도와 보였으며 이는 쌀전분의 특성의 차이가 소화율에 영향을 미친 것으로 생각된다. 국내에서 생산된 4가지 쌀품종의 전분 특성, 소화율 특성이 다르게 나타났으며 이러한 결과는 쌀품종을 활용한 가공제품개발에 활용될...
된장의 소금농도를 10%에서 6%로 줄이고 알코올 또는 겨자, 마늘을 단독 혼합 첨가한 저식염 숙성 중 품질특성을 비교하였다. amylase 활성은 2-4주에 높았으며 겨자 첨가 된장이 후기에 낮은 활성을 보였다. 메주 koji 된장에 비하여 효소 활성이 낮았으며, protease는 중성보다 산성 protease 높았다. 효모수는 겨자나 알코올, 마늘의 첨가로 현저하게 줄었으나 세균수는 첨가구에서 조금 적었다. 산화환원전위는 겨자-마늘 된장에서 수분활성도의 저하는 심하였다. 중에 L-과 b-값이 저하가 심하였고 된장은 L-값이 낮았고 a-값이 pH는 마늘 적정산도의 증가가 심하였으나, 알코올의 적정산도와 산가는 환원당은 알코올-마늘과 높았으며, 생성은 겨자의 억제되었다. 아미노산성 질소는 마늘과 암모니아성 질소의 낮았다. 8주 숙성시킨 맛과 종합적인 기호도는 알코올과 알코올-마늘 양호하여 제조는 소금의 일부를 마늘로 대체하거나 이를 혼합하여 첨가하는 것이 효과적이었다.
