WebNov 1, 2024 · The carbohydrate fraction obtained with CyNMe2 showed relative high values of total dietary fiber (63 to 83%). The highest concentration of phenolic compounds was obtained after 24 h at 25 °C. Seven major species of chlorogenic acids were detected within the phenolic fraction, ranging from 1.83 to 7.16 mg g −1 of dry matter. CyNMe2 generated microfractures and hollow openings in the solid matrix through ion pair formation that releases the phospholipids from the solid matrix. In comparison to Folch, CyNMe2 resulted in higher concentration of phospholipids (up to 9-fold increment), and it provided a different relative distribution, where phosphatidylcholine and ...

WebA tertiary amine (N,N-dimethylcyclohexylamine, CyNMe2) was used as a switchable hydrophilicity solvent (SHS) for extracting phospholipids (PLs) from raw cream (RC), buttermilk (BM), concentrated buttermilk (CBM), and beta-serum (BS). The SHS extractions were performed with varying solvent-sample weight ratio at room temperature.
