Sustainability in Analytical Chemistry Illustrated by Pharmaceutical Nitrosamine Testing

ELECTROPHORESIS, EarlyView.
ABSTRACT Following the valsartan scandal in 2018, the testing of drug substances and drug products for N‐nitrosamines has become a critical and mandatory quality control measure. The European Pharmacopoeia chapter 2.5.42 currently describes three analytical methods for this purpose: HPLC–MS/MS, GC–MS, and GC–MS/MS.

Peach Kernel Oil Modulates Lipid Metabolism Disorder in ApoEa CRISPR/Cas9 Gene‐Disrupted Zebrafish

Food Frontiers, EarlyView.
In this study, we used CRISPR/Cas9 gene editing technology to establish a lipid metabolism disorder model of ApoEa mutant zebrafish. We applied peach kernel oil to this model and studied the mechanism of peach kernel oil regulating lipid disorder in combination with transcriptomics.

Comparative Analysis of Intermediate and Advanced Maillard Reaction Products in Three Types of Commercial Edible Mushroom Products

Food Frontiers, EarlyView.
ABSTRACT In recent years, rising consumption of mushroom‐based foods has highlighted concerns over the formation of harmful Maillard reaction products (HMRPs) during thermal processing. However, limited information is available on the occurrence of intermediate and advanced HMRPs, such as α‐dicarbonyl compounds (α‐DCs) and advanced glycation end ...

Purification, Structural Characterization, and Anticancer Activity of the Polysaccharide From Sea Red Rice Bran

Food Frontiers, EarlyView.
Sea red rice bran polysaccharides were separated and purified by DEAE‐52 column chromatography, yielding three components: SRBP‐I, II, and III. Moreover, all three are pentosan‐type polysaccharides predominantly composed of mannose. Among them, SRBP‐I demonstrated the most potent inhibitory effect on HeLa cells. Further investigation indicated that the
