Purple sweet potatoes (PSP) have been used as a natural food colorant with high acylated anthocyanins concentrations. Commercially extracting pigments from PSP can be challenging due to firm texture and high polyphenol oxidase (PPO) content. These studies evaluated hot water immersions (30, 50, 70,
High-performance capillary electrophoresis (HPCE) is rapidly gaining acceptance as an analytical tool for the study of biological macromolecules. In the present study, the utility of HPCE for separation of glycoproteins is highlighted using a pure ovalbumin preparation. Ovalbumin, the 43-kDa
A method was developed to selectively methyl esterify and then cleave GalA residues in pectic polysaccharides. The method was optimized using a rhamnogalacturonan (RG) from Arabidopsis mucilage as a model compound. The carboxyl group of the GalA residues in the RG was selectively methyl esterified
