Food safety is closely related to people's lives and health, and is related to social harmony and stability and stable economic operation. Efficient detection techniques and methods are of great significance to ensure food safety. Ultra performance liquid chromatography-tandem mass spectrometry...

Objective To establish a method for simultaneous determination of amantadine, rimantadine, morpholine and acyclovir residues in honey by ultra performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS). Methods The samples were dissolved in 20% acetonitrile-water (containing 0.2%...

In order to detect the freshness of fish rapidly, electric conductivity method was applied to measure the electric conductivity changes during storage to verify its feasibility. Variations of the electric conductivity, aerobic bacterial count, total volatile basic nitrogen (TVB-N), 2-thiobarbituric ...

Antibiotic residues in foods have aroused wide public concern because of their potential side-effects. It is imperative to develop a simple, accurate and reliable method for the detection of antibiotic residues in foods. In this paper, we report a novel, facile and sensitive method for the...

Three typical contaminant bacteria, namely, Gluconobacter, Acetobacter, and Lactobacillus, were selected from fermented milk. The strong specific genes were screened as target sequences, and the droplet digital polymerase chain reaction (ddPCR) amplification system and reaction conditions were...

An electrochemical immunosensor based on self-assembled gold nanorods on glassy carbon electrode was developed for label-free and sensitive detection of Staphylococcus aureus (S. aureus). The gold nanorods were firstly assembled on the electrode surface by using poly-(diallyldimethylammonium...

Food safety is a major livelihood issue in China. A food safety supervision system is the most important measure to ensure food safety. However, the lack of professional supervision measures is the biggest obstacle to the improvement of food safety supervision in China. By analyzing and drawing on...

Food-borne diseases caused by microbial contamination have always been a matter of great concern to human beings. Hence, the research on these problems has never stopped. With the development of microorganism amplification technology, more and more detection methods have come into our vision....

In order to realize the early warning of cucumber spoilage during its storage by hyperspectral technology, two batches of cucumbers with different storage dates and different varieties were selected for hyperspectral information collection. The characteristic wavelengths were extracted by principal ...
