The detection of H₂O₂ in milk was carried out using a CIC-biosensor based on collagen-immobilized catalase (CIC) and a dissolved oxygen probe. The CIC-biosensor response was fastest at pH 7.0 at 30°C. Further, the biosensor exhibited responses over a H₂O₂ concentration range from 1.47 × 10^-6 mol/L...

Objective: To research the performance of the blocking agent and storage stable liquid of immunomagnetic beads, and to guarantee the capture efficiency of microorganism. Methods: The gelatin and casein were used as blocking agent and preservation solution in the preparation of anti-Salmonella...

Objective: To analyze the general situation of food safety in Shandong province in 2019, and find the main problems of food safety spot check. Methods: The data and results of sampling inspection of 47 notices on sampling inspection of food safety supervision issued by the Shandong provincial...

Food companies are seeking natural antibacterial alternatives to chemical preservatives like sodium benzoate and potassium sorbate due to the increasing demand for natural and healthy diets. Nisin, a polypeptide bacteriocin produced by lactic acid and other beneficial bacteria, offers natural,...

Antimicrobial agents are natural, harmless, and clean label compounds that inhibit microbial activity. Their application in food processing can meet the consumer demands for minimally processed foods. This article reviewed the methods of antimicrobial agent-assisted heat treatment. It focused on...

Herein, N, S co-doped carbon quantum dots (N, S-CDs) with high absolute quantitative yield (Abs-QY) of 50.2% were produced by hydrothermal treatment of food residue crayfish shells. A new detection method of thiamphenicol (TAP) and its analogues was established by discovering the obvious...

This study evaluated the effects of low-molecular-mass chitosan oligosaccharides (COS) on the microbiota and quality of silver carp fillets stored at 4°C. The fish fillets were divided randomly into two groups: control and 0.5 g/100 mL COS treatment. To evaluate the preservative effect of COS,...

A magnetic solid phase extraction method based on magnetic covalent organic frameworks (TpBD@Fe₃O₄; 2,4,6-triformylphloroglucinol (Tp) and benzidine (BD)) combined with high performance liquid chromatography has been developed to detect the sulfonamides including sulfadiazine, sulfamerazine,...

This paper reports the development of a novel probe based on magnetic room-temperature phosphorescence quantum dots with molecularly imprinted polymers (MQD-MIPs) for the rapid detection of trace norfloxacin (NFX) residual in complex food matrix. The highly selective probe was constructed by...

Dry-cured meat products are susceptible to contamination by fungi during their production and storage. Some filamentous fungi in dry-cured meat products can produce mycotoxins under certain conditions, increasing the risk of toxin contamination in meat products and threatening human health...
