In order to seek high profit, businesses mix beef and mutton with cheap meat, such as duck, pork, and chicken. Five pairs of primers were designed for quintuple droplet digital PCR (qddPCR) of specific genomic regions from five selected species and specificity and amplification efficiency were determined. The mixed DNA template with an equal copy number was used for detecting the accuracy and limit of multiplex PCR. The results showed that the primers and probes of the five selected species had good specificity with the minimum number of detection copies: 0.15 copies/µL beef (), 0.28 copies/μL duck (), 0.37 copies/μL pork (), 0.39 copies/μL chicken (), and 0.41 copies/μL mutton (), respectively. The five sets of primers and probes could quickly judge whether the specified meat components existed in the food commodities.

The growth of population and changes in dietary structure have led to a continuous increase in demand for livestock and poultry products, resulting in the increase of the gaseous reactive nitrogen (GNr) emissions from livestock and poultry breeding systems and posing a threat to the human and ecosystem health. The characteristics from GNr emissions of six livestock and poultry breeding systems at the provincial level of China in 2020 were evaluated with the framework of life cycle analysis. Additionally, this study explored the impact of silage maize replacing traditional maize as feed on reducing GNr emissions.

Objective: Although an association exists between dietary habits and head and neck cancer (HNC), the direct cause-and-effect connection remains elusive. Our objective was to investigate the causal associations between dietary factors and the likelihood of developing HNC.
Methods: Genome-wide association study (GWAS) summary statistics for dietary habits were screened from the UK Biobank, the OncoArray Oral Cavity and Oropharyngeal Cancer consortium, and the FinnGen biobank for HNC.

Background: High-fat diets are associated with metabolic syndrome, cardiovascular diseases, and liver disorders. Beef and mutton, both widely consumed meats, are significant sources of animal fat, while soybean oil, a commonly used cooking oil, is a prominent source of plant-derived fat. This study aimed to compare the effects of regular consumption of beef fat, mutton fat, and soybean oil in mice to assess potential health risks.

Amino acids are an essential source of human protein, and their content and composition are the main factors determining food protein utilization rate. Determining amino acids is essential in the component analysis of food. Therefore, a groundbreaking technique was developed utilizing ultra-high performance liquid chromatography interfaced with a triple quadrupole mass spectrometer (UHPLC-QQQ-MS/MS) for concurrently quantifying 18 amino acids across various types of meat.
