This study aimed to assess the health risks of α-chaconine and α-solanine, glycoalkaloids (GAs) commonly found in potatoes, Korean population using both deterministic probabilistic approaches. A total 146 potato samples, including raw processed varieties, were analyzed for these GAs a validated high-performance liquid chromatography-photodiode array method. detected 63.0% with concentrations ranging from 2.29 172.19 mg kg-1. Deterministic risk assessments, based on daily dietary exposure...
The purpose of this study was to isolate functional Bacillus strains from Korean fermented soybeans and evaluate their potential as probiotics. L-asparaginase activity MKHJ 1-1 the highest among 162 strains. This strain showed nonhemolysis did not produce β-glucuronidase. Among nine target bacteria, inhibited growth Escherichia coli, Pseudomonas aeruginosa, Shigella sonnei, flexneri, Klebsiella pneumoniae, Staphylococcus aureus, cereus. 16S rRNA gene sequence analysis resulted in identified...
Various neurotransmitters are involved in regulating stress systems. In this study, we investigated the effects of gamma-aminobutyric acid-rich rice bran extract (GRBe) mice stressed by forced swimming and tail suspension tests. Four weeks oral administration GRBe (500–2000 mg/kg) reduced levels dopamine corticosterone blood brain while increasing serotonin levels. was not only but also sleep obesity-related genes. Modern society experiences diverse tense lives because urbanization...
A Gram-staining-positive, strictly aerobic, non-spore-forming, rod-shaped bacterial strain, CAU 9163(T), was isolated from marine sediment collected in the Republic of Korea and its taxonomic position investigated using a polyphasic approach. The novel strain grew optimally at 30 °C pH 8.0. In phylogenetic analysis based on 16S rRNA gene sequences, 9163(T) formed hitherto unknown lineage within order Bacillales, which contains genera Planomicrobium, Planococcus, Sporosarcina,...
This study was performed to examine the microorganisms responsible for high tyramine content of Cheonggukjang, a traditional Korean fermented soy food, and establish technology controlling growth these microorganisms. The in 13 collected Cheonggukjang samples averaged 604.9 mg/kg. Since measured from most sufficient cause harm human body, it is necessary control its production food. Enterococci were confirmed be bacterial species producing through microbial examination present numbers not...
본 실험의 복분자종자유는 리놀렌산 238.3 mg/g, 리놀레산과 감마리놀렌산 427.1 mg/g을 포함하며 이는 고시된 범위내의 섭취량이므로 독성시험 없이 4주 동안 매일 경구 투여로 암컷과 수컷 쥐 모두에게 섭취하도록 하였다. 또한 성인정상체중을 약 60 kg으로 설정하고 kg의 성인이 하루 1 g, 2 g을 각각 섭취할 때의 혈중 지방의 감소 효과를 알아보기 위해 급이군의 설정을 g/60 kg BW/d(BSO g), g)로 정하였다. 양성대조군의 경우에 판매되는 연어유 1,000 mg 캡슐을 2정 섭취하는 것을 권장하였고, 이에 맞추어 BW/d로 설정하게 되었다. 실험기간 종료 후 마우스를 희생시켜 혈액을 얻었으며, 복분자종자유(BSO g)를 섭취한 마우스에서 총콜레스테롤 및 HDL, LDL/VLDL-콜레스테롤과 중성지방이 유의적으로 감소하는 확인할 수 있었다(P0.05). 이를 종합해 보았을 때 고지혈증 상태를 개선하고 미약하지만 항응고 활성을 통해 혈액의 항상성을...
The purpose of this study was to estimate the preference, intake frequency and eating behavior for kimchi as well analyze differences by gender among fourth sixth grade students (n=410) in a Chungnam region. Approximately 64% liked spicy taste kimchi, 75.9% saltiness, 48.5% well-fermented kimchi. disliking factors were its sour (38.5%), strong scent (20.1%), salty (15.4%). most preferred type Baechukimchi, followed Kkakduki, Yeolmukimchi, Chonggakkimchi. Further, frequently consumed...
본 연구에서는 쌀가루 대신 새봉 품종의 감자분말을 10, 30, 50, 70, 100%로 대체하여 Saccharomyces cerevisiae와 Leuconostoc mesenteroides로 발효한 후 제조한 증편의 품질 특성과 저장성을 살펴보았다. RVA로 측정한 증편 반죽의 호화개시온도는 발효 후에 증가하였으며, 감자 첨가비율이 증가할수록 낮아졌다. 발효반죽의 최고･최저･최종점도, breakdown, setback 값은 전보다 낮아졌으며 이는 발효에 의해 생산된 유기산의 영향 때문으로 보인다. S. L. 값이 감소하여 전분입자의 안정성은 높아지고, 노화 진행이 지연되는 것을 알 수 있었다. 또한, 감자분말 첨가시 대조군보다 곰팡이 형성이 늦게 되거나 10일간 상온에서 곰팡이의 증식이 관찰되지 않기도 하였다. 높아질수록 a값과 b값, 양은 증가하였으나 L값은 감소하였다. 물성특성에서는 첨가할수록 경도, 응집성, 점착성, 씹힘성이 저장 기간에 노화현상을 쉽게 볼 있는 경도는...
To investigate the texture and cooking properties of garaetteok elaborated with potato flour, experimental products were replacing partially rice traditionally used, nonfermented (NF) or fermented flour Bacillus subtilis (BS) Leuconostoc mesenteroides (LM) in percentages 15% (NF15, BS15, LM15) 20% (NF20, BS20, LM20). The control product (CON) was made using only flours. pH significantly lower BS LM groups compared to CON NF. Titratable acidity highest BS20 LM15. showed similar textural...
