This study investigated the efficacy and mechanism of traditionally made kochujang(TMK) with different capsaicin levels to alleviate memory impairment in rats with scopolamine-induced amnesia. Sprague-Dawley male rats were administered scopolamine (2 mg/kg bw/day) intraperitoneally to suppress the parasympathetic nervous system(PNS) and induce memory impairment. The rats were divided into four experimental groups, each consuming a diet containing 1 % kochujang in a 43-energy% high-fat diet(HFD) for 8 weeks.

We investigated the effects of different types of long-term fermented soybeans (traditionally made doenjang; TMD) on glucose and bone metabolism and memory function in ovariectomized (OVX) rats. The rats were categorized into six groups: Control, cooked unfermented soybeans (CSB), and four TMDs based on () and biogenic amine contents analyzed previously: high (HS) and high biogenic amines (HA; HSHA), low (LS) and HA (LSHA), HS and low biogenic amines (LA; HSLA), and LS and LA (LSLA). The rats in the CSB and TMD groups fed orally had a 4% high-fat diet for 12 weeks.

Introduction: Jang is a fermented soybean paste containing salt and is traditionally used as a substitute for salt to enhance the flavor of foods in Korea. It has been speculated that regular consumption of Jang may lower the risk of metabolic syndrome (MetS). We hypothesized that Jang intake was associated with the risk of MetS and its components after adjusting for potential confounders, including sodium intake.

A high salt intake may exacerbate menopausal symptoms and substituting for different types of traditionally made kanjang (TMK; soy sauce) may prevent it. This study examined whether substituting salt with lyophilized TMK containing low and high and biogenic amines in a high-fat diet might modulate the menopausal symptoms and the energy, glucose, and lipid metabolism in ovariectomized (OVX) rats. They were categorized into salt (Control), TMK with high and low biogenic amines (HBLB), TMK with high and high biogenic amines (HBHB), TMK with low and low biogenic amines (LBLB), and TMK with low and high biogenic amines (LBHB).

Short-term fermented soybeans (chungkookjang) with specific spp. have anti-obesity, antidiabetic, and anti-stroke functions. We examined the hypothesis that the long-term consumption of SCGB 1 fermented (CKJ1) and SCDB 291 (CKJ291) chungkookjang can alleviate clinical symptoms and hyperglycemia after ischemic stroke by promoting the gut microbiota-brain axis.

We determined that consuming chungkookjang fermented by (BS) or (BA) alleviated hyperglycemia in partially pancreatectomized (Px) rats, an Asian type 2 diabetic (T2D) animal model. Px rats had deteriorated glucose metabolism with decreased glucose-stimulated insulin secretion and insulin sensitivity. Insulin secretion capacity was improved in the ascending order of the Px-control, positive control (3 mg of metformin/kg of body weight), BS (4.

Article Synopsis
  • Chungkookjang, a traditional Korean fermented soybean food, shows potential benefits in protecting against ischemic stroke and managing post-stroke hyperglycemia in gerbils, particularly when made with specific strains of Bacillus amyloliquefaciens.
  • Gerbils fed diets including these strains exhibited improved neurological function, memory, strength, and blood flow, alongside reduced inflammation markers compared to a negative control group.
  • This study suggests that chungkookjang may enhance gut microbiome health, improve brain blood flow, and lower inflammation, indicating its potential as a functional food for stroke recovery.

We hypothesized that soybeans fermented with spp. for 48 h (chungkookjang) would be rich in poly-γ-glutamate (γ-PGA) and would have greater efficacy for improving insulin sensitivity and insulin secretion in 3T3-L1 adipocytes, min6 cells, and PC12 neuronal cells. We screened 20 different strains of and spp.
