Simultaneous determination of residues of 16 aminoglycosides residues in livestock and poultry meat based on ion pair interaction by solid-phase extraction and liquid chromatography-tandem mass spectrometry.

Aminoglycosides (AGs) are broad-spectrum bactericidal antibiotics commonly used in animal husbandry. Residues of AGs in food can enter the human body through the food chain and biomagnification. Due to the specific structure and properties of AGs, it is difficult to achieve adequate extraction and separation during analysis, often giving rise to matrix effects.

Physicochemical and functional properties of cinnamon essential oil emulsions stabilized by galactomannan-rich aqueous extract from Gleditsia sinensis seeds and soy protein isolate.

Cinnamon essential oil has gained widespread attention in the food industry as a safe and effective preservative. However, its low water solubility and high volatility limit its application in food, making the use of natural emulsifiers for its emulsification an increasingly popular focus of research. This study focuses on the extraction of galactomannan-rich aqueous extracts from Gleditsia sinensis seeds using a low-energy, low-pollution microwave-assisted method.
