The feasibility of the two methodologies was confirmed to compare results determining mung bean origins using Raman and Near-Infrared (NIR) spectroscopy. Spectra from beans collected in Baicheng City, Jilin Province; Dorbod Mongol Autonomous, Tailai County, Heilongjiang Sishui Shandong Province, China, were analyzed. We established a traceability model Principal Component Analysis combined with K-nearest neighbor method efficacy these methods discriminating beans. total cumulative variance...

Abstract Due to the similarity in grain and difference market value among many rice varieties, deliberate mislabeling adulteration has become a serious problem. To check authenticity, we aimed discriminate varieties based on their volatile organic compounds (VOCs) composition by headspace solid phase microextraction (HS-SPME) coupled with gas chromatography mass spectrometry (GC–MS). The VOC profiles of Wuyoudao 4 from nine sites Wuchang were compared 11 cultivar other regions. Multivariate...

Pu-erh tea is a famous worldwide, and identification of the geographical origin can not only protect manufacture’s interests, but also boost consumers’ confidence. However, tree age may influence fingerprints tea. In order to study effects on interactions stable isotopes multi-elements tea, 53 leaves with three different stages from areas in Yunnan were collected 2023. The δ13C, δ15N values 25 elements determined analyzed. results showed that δ15N, Mg, Mn, Fe, Cu, Zn, Rb, Sr, Y, La, Pr, Nd,...

Studies have shown that inhibiting inflammation and regulating intestinal microflora imbalance is a significant factor in controlling the development of type 2 diabetes mellitus (T2DM). This experiment studied protective effect polyphenol extract from germinated mung beans on diabetic C57BL/6 mice. Results Fasting blood glucose (FBG) was decreased, tolerance increased, insulin resistance serum lipid indexes T2DM mice were improved, enzyme activities alanine aminotransferase (ALT) aspartate...

To gain an in-depth understanding of the diversity and composition soil Acidobacteria in five different forest types typical temperate ecosystems to explore their relationship with nutrients. The was determined by high-throughput sequencing technology. Soil Acidobacteria’s alpha-diversity index nutrient content differed significantly among types. β-diversity also varied across Acidobacterial genera, such as Acidobacteria_Gp1, Acidobacteria_Gp4, Acidobacteria_Gp17, play key roles forests. RDA...

Abstract In the context of bulk grain container transportation, complex logistics can lead to mildew and subsequent economic losses. Therefore, there is a pressing need explore swift real‐time detection technology. Our investigation, simulating actual transportation conditions, revealed that Aspergillus , Penicillium Rhizopus were primary molds responsible for soybean during transportation. Utilizing gas chromatography‐ion migration spectroscopy (GC‐IMS), we analyzed correlation between...

The study aims to investigate whether the multielement analysis result can be used as a fingerprint identify geographical origin of Wuchang rice. element contents rice and soil samples from three regions in China (Wuchang, Qiqihar, Jiamusi) were analyzed. concentrations 16 elements (Na, Mg, Al, K, Ca, V, Mn, Fe, Co, Cu, Zn, As, Rb, Sr, Cd, Pb) 194 112 harvest season 2013 2014 determined. variance linear discriminant performed analyze variation among genotypes classify origins Only Cu showed...

This study aims to address the gap in understanding of impact sample quantity, traceability range, and shelf life on accuracy mung bean origin models based near-infrared spectroscopy. Mung beans from Baicheng City, Jilin Province, Dorbod Mongol Autonomous, Tailai County, Heilongjiang Sishui Shandong China, were used. Through spectral acquisition (12,000–4000 cm−1) preprocessing (Standardization, Savitzky–Golay, Standard Normal Variate, Multiplicative Scatter Correction) samples, total...

Abstract For the past several decades, only a few studies were conducted on change in immature rice liposomes during seed development. To evaluate and compare lipid material of different degrees developing grains, this paper focused fresh seeds from one most popular species Dasan divided into five growth periods. The components rice, especially γ‐oryzanol fatty acids equipped with extremely beneficial phytonutrients, investigated. results illustrated that level extracted liposome increased...

The stability of mineral elements in rice is not only related to genotype and environmental factors, it also processing precision. In this study, japonica from Jiansanjiang, Heilongjiang province, China, was analyzed divided into five grades. Analysis the using inductively coupled plasma-mass spectrometry (ICP-MS) indicated that Na, Mg, Al, K, Ca, Cr, Mn, Fe, Co, Cu, Zn, Rb, Sr Ba contents differed due influence different By removing which were significantly changed by processing, we able...

This study employed electronic nose technology to assess the mold levels in soybeans, conducting analyses on artificially inoculated soybeans with five strains of fungi and distinguishing them from naturally moldy soybeans. Principal component analysis (PCA) linear discriminant (LDA) were used evaluate samples. The results revealed that most influential sensor was W2W, which is sensitive organic sulfur compounds, followed by W1W (primarily responsive inorganic compounds), W5S (sensitive...

In order to analyze the mycotoxins in corn, modified QuEChERS high-performance liquid chromatography was applied extract, clean up, and detect a nonpolar system. The impurities such as fat protein were removed from corn sample, sample solution have almost no effect on extraction efficiency. proposed method leads greater choice of mycotoxin-extraction solvents high-fat-solid samples. An appropriate solvent selected, pretreatment conditions optimized, cleanup high-fat solids enhanced. By...
