STAR (STEM Teacher and Researcher) Presentations

Milk proteins within their structure and sequence, contain peptides that exhibit antithrombotic, immunomodulatory, antimicrobial, antihypertensive, and other bioactivities. These peptides are released as the enzymes cleave milk proteins at certain locations of the amino acid chains. In this research, four different substrates were hydrolyzed with the gastrointestinal enzymes, pepsin and trypsin. The substrates were buttermilk (BM) and whey buttermilk (WBM), which are waste products of butter and cheese production, and supercritical CO2 fluid (SFE) treated buttermilk (S-BM) and whey buttermilk (S-WBM). SFE acts as a solvent which removes triglycerides from the substrates and changes the overall composition of samples ...

A Comparative Study Of The Fractionation Of Regular Buttermilk And Whey Buttermilk By Microfiltration, Pierre Morin, Yves Pouliot, Rafael Jiménez-Flores

Dairy Science

The use of a ceramic microfiltration (MF) membrane for the fractionation of buttermilk and whey buttermilk obtained from pilot scale churning of cream and whey cream from industrial sources has been studied. Whey buttermilk contained comparable amounts of phospholipids compared to regular buttermilk but its protein content was lower due to the absence of caseins. However, it was found that lipid content of whey cream did vary significantly between lots resulting in important variations in the fat content of whey buttermilk. A twofold MF concentration of regular buttermilk doubled its phospholipids content whereas that of whey buttermilk was increased by ...
