Optimization of Jiuzao protein hydrolysis conditions and antioxidant activity in vivo of Jiuzao tetrapeptide Asp-Arg-Glu-Leu by elevating the Nrf2/Keap1-p38/PI3K-MafK signaling pathway

Abstract

Tetrapeptide Asp-Arg-Glu-Leu (DREL) was isolated from Jiuzao protein hydrolysates (JPHs) by alkaline proteinase (AP) and exhibited antioxidant activity by HepG2 cell model in the previous study. In this study, hydrolysis...

Unraveling variation on the profile aroma compounds of strong aroma type of Baijiu in different regions by molecular matrix analysis and olfactory analysis

“…Methyl lactate and 4-octanol were purchased from Tokyo Chemical Industry Co., Ltd. (Tokyo, Japan). 2-Ethylhexanoic acid, butyl benzoate, 2-butanol, 1-propanol, 2-pentanol, 2methyl-1-butanol, 3-methyl-1-butanol, 2-hexanol, 1-pentanol, 2heptanol, 1-hexanol, 1-heptanol, 2,3-butanediol, 2-methylpropanol, 1-octanol, 2-furan methanol, furfural, 2-butylfuran, phenylacetaldehyde diethyl acetal, ethyl 3-phenylpropionate, phenylethyl alcohol, 4-ethyl-2-methoxyphenol, ethyl benzoate, 4-methylphenol, acetic acid, propanoic acid, 2-methylpropionic acid, butanoic acid, 3-methylbutanoic acid, 3…”

“…Moreover, research on Baijiu might adhere to the dual guidance about "avor" and "health" in the future, and more and more studies on Baijiu have been carried out. [1][2][3][4][5][6][7][8][9][10][11] Based on its aroma characteristics, Baijiu can be roughly divided into 12 aroma types. In particular, strong-aroma (i.e., Nongxiangxing), sauce-aroma, light-aroma, and rice-aroma are deemed to be the four basic Baijiu aroma types.…”

Computer-Assisted Enzyme-Cocktail Approach Highly Improves Bioethanol Yield

“…Bioethanol is a promising liquid fuel to fulfill the growing energy demand and sustainable economy, resulting in a positive impact on rural areas, the environment, and energy security. − Over the last few years, significant research efforts and advanced technologies (e.g., crop improvement and modification, , high-efficiency yeast, by-product recovery and utilization, ,− high solid use, , fractionation at the front or back end, , and control of process conditions , ) have been developed to enhance whole bioethanol process economics and increase the profitability. However, higher biomass utilization and ethanol yield are still highly desired in the industry.…”

Enhancement of polysaccharides production using microparticle enhanced technology by Paraisaria dubia

“…The hydroxyl radical activity was measured based on previous reports [ 43 , 45 ]. Briefly, 1 mL of the polysaccharide solution (0.1, 0.5, 1.0, 2.0, 3.0, or 4.0 mg/mL) was mixed with 1.0 mL of an FeSO 4 solution (2 mmol/L) and 1.0 mL salicylic acid–ethanol solution (6 mmol/L).…”
