Characterization of Key Aroma Compounds in Aged Chinese Baijiu Based on Sensory and Quantitative Analysis: Emphasis on the Contribution of Trace Compounds.

The characteristics and complexity of Baijiu are inseparable from the promotion of aging. While the impact of compounds such as alcohols, esters, and acids on the aroma of aged Baijiu has been extensively studied, the role of other trace compounds in the aging process should not be overlooked. To further investigate the relationship between volatile compounds and the aging of Baijiu, sensomics research methods were employed to analyze profiles of young and aged Baijiu.

Baijiu adulteration practices, driven by profit motives, seriously endanger consumer health and disrupt the market. This study combined hyperspectral imaging with deep learning for adulteration detection. In the classification of authentic and adulterated samples, PSO-SVM achieved 97.

Multi-scale structural heterogeneity of glutinous rice starch in different varieties: A determinant of physicochemical properties and digestibility.

This study systematically investigated the multi-scale structure of glutinous rice starches (WK1, WK2, WK3, TN2072, and HY) from five varieties, and analyzed physicochemical properties and in vitro digestibility to reveal structure-property relationships. TN2072 starch exhibited distinctive structural characteristics showing a lower gyration radius (245.77 nm) and crystalline lamellar thickness (5.

Screening and identification of strains for high quality and antioxidant activity of Baijiu from strong-flavor Daqu and analysis of microbial synergistic effects.

In this study, functional strains with strong fermentation characteristics were isolated from Strong-flavor Daqu and evaluated for their ability to enhance the quality and antioxidant activity of Baijiu. Bacillus velezensis (S1), Bacillus subtilis (S12), and Escherichia coli (S16) were identified as key strains. Fermentation experiments with different inoculation amounts and combinations revealed synergistic effects on Baijiu quality and antioxidant activity.

Modification of Structure, Pasting, and In Vitro Digestion Properties of Glutinous Rice Starch by Different Lactic Acid Bacteria Fermentation.

This research evaluated the effect of fermentation with 11122, 23184, and 1011 on structure, pasting, and in vitro digestion properties of glutinous rice starch varying in TN and HY genotype, respectively. The results showed that fermentation decreased the weight-average molecular weight and increased the radius of gyration. The short chain was increased by degrading the medium chain (B, DP 24-35) of amorphous in starch, which directly led to the increase of branching degree and rearrangement of the starch chain.

Quick classification of strong-aroma types of base Baijiu using potentiometric and voltammetric electronic tongue combined with chemometric techniques.

Nowadays, the classification of strong-aroma types of base Baijiu (base SAB) is mainly achieved by human sensory evaluation. However, prolonged tasting brings difficulties for sommeliers in guaranteeing the consistency of results, and may even cause health problems. Herein, an electronic tongue (E-Tongue) combined with a gas chromatography-mass spectrometry (GC-MS) method was successfully developed to grade high-alcoholic base SAB.

Constructing simplified microbial consortia to improve the key flavour compounds during strong aroma-type Baijiu fermentation.

The ester compounds play key roles in maintaining the sensory characteristics of alcoholic beverages. For strong aroma-type Baijiu fermentation, the volatile acids from pit mud microbes are key precursors for ester synthesis. However, the volatile acids can only be efficiently synthesized by the pit mud microbes in grains which attaches to pit mud.

Pulse electric field assisted process for extraction of Jiuzao glutelin extract and its physicochemical properties and biological activities investigation.

Jiuzao is the residue of baijiu distillation. In this study, pulse electric field (PEF) was used to improve the extraction efficiency of Jiuzao glutelin extract (JGE). The species, physicochemical properties, and biological activities of JGE were investigated to expand its utilization.

Untargeted Headspace-Gas Chromatography-Ion Mobility Spectrometry in Combination with Chemometrics for Detecting the Age of Chinese Liquor (Baijiu).

This paper proposes the combination of headspace-gas chromatography-ion mobility spectrometry (HS-GC-IMS) and chemometrics as a method to detect the age of Chinese liquor (Baijiu). Headspace conditions were optimized through single-factor optimization experiments. The optimal sample preparation involved diluting Baijiu with saturated brine to 15% alcohol by volume.

Vintage analysis of Chinese Baijiu by GC and H NMR combined with multivariable analysis.

Economical-driven counterfeit and inferior aged Chinese Baijiu has caused serious concern of publicity in China. In this study, a total of 167 authentic Chinese Baijiu samples with different vintages including 3 flavor types were carefully collected. Gas chromatography (GC) was used to determine main volatile components and proton nuclear magnetic resonance (H NMR) spectroscopy was employed to obtain non-targeted fingerprints of Chinese Baijiu samples.

Clinical analysis of application of antibiotic bone cement spacer combined with membrane induction technology in treatment of osteomyelitis after femoral intramedullary nail operation - A case series.

Clinical analysis of antibiotic bone cement spacer combined with membrane induction technology in the treatment of osteomyelitis after intramedullary nail fixation operation for femoral shaft fracture was retrospectively performed on 12 cases in Department of Orthopaedics Centre, Renmin Hospital, Hubei University of Medicine from February 2013 to November 2016. The healing time of bone defect, infection recurrence and other complications were observed. Membrane induced series treatment scheme was given to all patients.

Prokaryotic communities in multidimensional bottom-pit-mud from old and young pits used for the production of Chinese Strong-Flavor Baijiu.

The pit mud (PM) prokaryotic communities with obvious difference between old and young PM is essential for solid-fermentation of Chinese Strong-Flavor Baijiu. The bottom-PM (BPM) is considered more important. In this study, the multidimensional prokaryotic communities of old and young BPMs were investigated.

MicroRNA-497-5p Suppresses Tumor Cell Growth of Osteosarcoma by Targeting ADP Ribosylation Factor-Like Protein 2.

Background: Osteosarcoma (OS) is a frequent primary bone malignancy. MicroRNA-497-5p (miR-497-5p) has been recently reported to be downregulated in angiosarcoma, but its potential role in OS remains unclear.

Methods: Quantitative real-time polymerase chain reaction was used to determine miR-497-5p expression in OS tissues and cell lines.

Clinical values of urinary IL-6 in asymptomatic renal hematuria and renal hematuria with proteins.

Renal hematuria is caused by glomerular disease. Under pathological conditions, the distribution of interleukin-6 (IL-6) in kidney tissue is abnormal and urinary IL-6 levels are increased. Abnormal IL-6 secretion promotes the hyperplasia of mesangial cells and matrix and, thus, affects the permeability of the glomerular filtration membrane.

Effects of combined prednisone + fluvastatin on cholesterol and bilirubin in pediatric patients with minimal change nephropathy.

Background: Nephrotic syndrome is associated with hyperlipidemia and low serum bilirubin. Corticosteroids and statins are routinely administered to patients with this syndrome. However, knowledge of the mechanisms that underlie hyperlipidemia is incomplete.
