Vegetables are an indispensable food in our daily diet. They can easily absorb nitrite, causing food safety problems. This paper determines the nitrite content of vegetables under different conditions and provide a basis for assessing food safety risks. Different conditions of vegetable storage,...

A novelty high-throughput semi-automatic sample clean-up method was developed and used for rapid analysis of 9 drug residues in fish muscle tissues combined with high-performance liquid chromatography/quadrupole-linear ion trap mass spectrometry (HPLC-QTRAP-MS/MS). The target compounds were...

Objective: To study the use of packaging materials for tea in China and establish the database of surface area to volume ratios (S/V) of different food contact materials for different types of tea. Methods: Seven categories and 413 tea samples with different packaging forms were purchased from...

Objective: To analyze existing problems and risks found in the food safety supervision and sampling inspection of China in 2018~2019. Methods: The results of the national food safety supervision sampling in 2018~2019 were summarized to analyze the overall completion of the supervision sampling...

Glucocorticoids have anti-inflammatory and anti-allergic effects and are widely used in animal husbandry. Drug residues can be caused by inappropriate use of glucocorticoids. Meanwhile, glucocorticoids may also be added into health foods, threatening human health. This paper introduced the...

Objective: To verify the potential food safety hazards and provide a scientific basis for risk assessment, risk management and food safety standards formulation of ready-to-eat (RTE) food in Shanghai. Methods: From 2016 to 2020, 10 521 food samples of 20 kinds of RTE foods were collected in...

In order to timely discriminate wheat with different mildew rates, a Dyes/Dyes-Cu-MOF paper-based colorimetric sensor array was designed. Using array points to capture volatile gases of wheat with different mildew rates, and output RGB values. The correlation between ΔR/ΔG/ΔB values and odor...

Food analysis to ensure food safety and quality are relevant to all countries. This study aimed to develop a detection technique by combining recombinase polymerase amplification with CRISPR-Cas12a for food safety (termed RPA-Cas12a-FS). Our data showed that this novel method could be detected via...

Nitrite (NO_2^-) is widely present in meat products as a vital food preservative, while excessive nitrite is a serious carcinogen to human beings, developing a sensitive and selective nitrite detection method is of great significance for food safety. Herein, a novel luminescent metal organic...

This paper presented a brief introduction to the outbreak process and symptoms of coronavirus disease 2019 (COVID-19), elucidated the detection methods and transmission modes of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) that caused the disease, and summarized the survival time of ...
