Malachite green (MG), with teratogenic and reproductive toxicity, is widely misused as an antimicrobial agent, posing a serious threat to animal and human health. Therefore, this study developed a novel recyclable Surface-enhanced Raman scattering (SERS) hydrogel substrate, TiO2/MXene/PAA-PAM@AuNPs (TMPA), by forming a dual hydrogen-bond network using a PAA-PAM hydrogel matrix with TiO2/MXene and embedding

A high-throughput molecular emission spectrometry (MES) was developed for ethanol determination in alcoholic beverages. Samples, diluted 25–100 times with a 0.01 mol·L−1 HNO3 solution, were directly introduced into a solution anode glow discharge (SAGD), where evaporation, fragmentation, and excitation occurred, producing an intense CO molecular band at 206.8 nm. The method demonstrated high precision

Corn and potato starches with different amylose contents were subjected to ozone treatment. The process was performed on dry starches and starches previously moistened with water vapour. Electron paramagnetic resonance spectroscopy, X-ray diffraction and gel permeation chromatography were used to monitor the changes occurring in the starch structure during ozonation. Pasting characteristics, intrinsic

In this study, phenethyl isothiocyanate nanoemulsion (PNE) was formulated for creating composite films with pectin and chitosan. Two types of PNE/pectin/chitosan (PNE-PC) films (PNE-PC1, PNE-PC2) were made by introducing PNE into films with different pectin/chitosan (PC) contents. Compared to PC films, PNE-PC films showed greater hydrophilicity and improved elongation at break, with Fourier transform

Freshness deterioration of salmon during cold storage poses significant safety concerns, highlighting the need for real-time monitoring strategies. Herein, a novel starch-pectin film incorporating Nisin-A and curcumin nano-emulsion (SP-NC film) was developed for real-time monitoring of salmon freshness. FTIR, XRD, and molecular dynamics simulations confirmed strong molecular compatibility and stable

Pyrrolizidine alkaloids (PAs) and tropane alkaloids (TAs) are phytotoxins that occur worldwide and are important contaminants of food, especially (herbal) teas. Their transfer rates to tea infusions strongly influence exposure estimates, but conflicting results have been obtained so far, making risk assessment uncertain. Therefore, infusions prepared under controlled conditions from artificially contaminated

The aim of this study was to identify novel antioxidant peptides from quinoa (Chenopodium quinoa wild.) protein hydrolysates, which were prepared using enzyme combination methods. Eleven novel antioxidant peptides were screened through in silico evaluation, and their structure-activity relationships were further investigated. Molecular docking studies indicated that GPGGGGKGEMF (GF-11) exhibited a

In this study, a simple and efficient vortex-assisted supramolecular solvent microextraction (VA-SUPRA-ME) method for the simultaneous extraction of 8 BMZs from freshwater fish was established using response surface methodology (RSM) and artificial neural network genetic algorithm (ANN-GA) based on the comprehensive score M from the entropy weight method. The SUPRAS was added to the fish matrix and

Nanoflower-like NiFe2O4 (NFO-NF) was synthesized and employed to develop a dispersive micro solid phase extraction procedure for copper. NFO-NF was characterized by Fourier-transform infrared spectroscopy (FT-IR), scanning transmission electron microscopy (STEM), scanning electron microscopy-dispersive X-ray spectroscopy (SEM-EDX), field emission scanning electron microscopy (FE-SEM), X-ray diffraction

Protein-polyphenol complexes have attracted increasing attention in the development of novel food ingredients owing to their potential health benefits. Purple rice (Oryza Sativa L.) is rich in proteins and polyphenols, particularly anthocyanins. This study investigated the effects of two extraction methods, alkaline extraction (0.2 % NaOH) and α-amylase degradation, on the structure, compositional

A systematic study was undertaken of the flavor disparities of Jiangxiang-flavor Baijiu produced across southern and northern China. Five non-volatile organic acids, seven amino acids, and twenty-one volatile compounds (OAV > 1) were identified, with 14 key aroma-active compounds determined through aroma omission and triangle tests. Quantitative targeted flavoromics and partition coefficient method

This study explores the tailoring opportunity of Eri pupae powder properties using instant controlled pressure drop (ICPD) treatment over traditional boiling treatment prior to drying. ICPD treatments were administered with steam pressures in the range 0.1–0.5 MPa and treatment time of 30–90 s, followed by instant decompression. Effects of treatment conditions on hydration, foaming, emulsion properties

Lactate is generally regarded as the product of glycolysis, which accumulates in postmortem muscle, but its role in protein regulation through lactylation remains unknown in meat science field. This study investigated the effects of lactylation in metabolic regulation of postmortem muscle to explore the functional roles of lactate in meat. Different doses of lactate were added to muscle homogenates

Mei (Prunus mume), the only floral-scented species within the Prunus genus, holds exceptional ornamental, edible, and medicinal value. By synergizing headspace solid-phase microextraction (HS-SPME) and organic solvent extraction (OSE) coupled with gas chromatography–mass spectrometry (GC–MS), we systematically detected 103 emitted and 83 endogenous volatiles from 67 mei cultivars and 3 congeneric species

Due to geographical indication advantage of Hongmeiren (HMR) citrus, economically motivated origin fraud has emerged, alongside significant differences in antioxidant components. This study employed benchtop visible and near-infrared (Vis-NIR) spectroscopy combined with machine learning models for simultaneously identifying geographical origins and quantifying antioxidant components in HMR citrus.

Rapid and accurate detection of Malachite Green (MG) residues in aquatic products is crucial for food safety and public health. Here, we strategically developed a multifunctional FeMICuMOF material through a self-supported molecular imprinting strategy and evaluated its application in electrochemical and smartphone-integrated colorimetric detection of MG. This design integrates an Fe3O4 core with a

Accurate assessment of meat freshness is critical for ensuring food safety, reducing waste, and maintaining quality control in the food industry. Efficient classification of meat into categories such as fresh, half-fresh, and spoiled is essential for producers, retailers, and consumers alike. This paper presents a deep learning-based method for meat freshness classification, comprising three main stages:
