New Milk Proteins Findings Reported from Consejo Nacl Invest Cient and Tecn

By a News Reporter-Staff News Editor at Life Science Weekly -- Fresh data on Proteins are presented in a new report. According to news reporting out of Buenos Aires, Argentina, by NewsRx editors, research stated, "The aim of this work was to build, to isolate and to characterize, core-shell microparticles composed of a core of thermally aggregated beta-lactoglobulin (beta-lg) covered by a shell of carboxymethylcellulose (CMC). The core-shell particles were obtained by mixing (beta-lg)(n) and CMC solutions at pH 7 and finally, decreasing the pH up to 4, promoting the adsorption of CMC on the protein core due their opposite electric charge."

Our news journalists obtained a quote from the research from Consejo Nacl Invest Cient and Tecn, "The core-shell microparticles were characterized by static laser light scattering (SLS), optical microscopy and atomic force microscopy (AFM). At pH 4, ( beta-lg)(n) showed a diameter similar to 200 nm, but after adding the polysaccharide had a diameter similar to 1 mu m. The microscopy corroborated the data obtained by SLS measurements."

According to the news editors, the research concluded: "Core-shell microparticles could be isolated by lyophilization and potentially applied as a fat replacement and/or a delivery systems for encapsulated substances in food formulations."
