Antiulcer and antiproliferative properties of spent brewer's yeast peptide extr...
Amorim, Maria M.; Pereira, Joana O.; Monteiro, Karin M.; Ruiz, Ana L.; Carvalho, João E.; Pinheiro, Hélder; Pintado, M. E.The main objective was to study the antiulcer and antiproliferative potential of yeast peptide extract for further incorporation into functional foods. Peptide concentrates were obtained by hydrolysis of spent brewer's yeast proteins followed by a filtration process. In order to prove the possible protection of gastric mucosa, an animal model with ulcerative lesions caused by oral administration of absolute eth...
Bioactive properties of peptides obtained from Argentinian defatted soy flour p...
Coscueta, Ezequiel R.; Amorim, Maria M.; Voss, Glenise B.; Nerli, Bibiana B.; Picó, Guillermo A.; Pintado, M. E.Enzymatic hydrolysis of soybean meal protein isolate (SPI) obtained under two temperature conditions with Corolase PP was studied, assessing the impact of hydrolysis on potential antioxidant and antihypertensive activities. The protein was isolated from soybean meal under controlled conditions of time and temperature (70 C, 1 h; 90 C, 30 min). Degree of hydrolysis assessed the progress of hydrolysis at differen...
Effect of composition of commercial whey protein preparations upon gelation at ...
Ramos, Óscar S.; Pereira, Joana O.; Silva, Sara I.; Amorim, Maria M.; Fernandes, João C.; Lopes-da-Silva, José A.; Pintado, Manuela E.The major goal of this research effort was to comprehensively characterize various whey protein products available in the market — including one whey protein isolate (WPI) and three whey protein concentrates (two forms of WPC 80, and WPC 50), with regard to the effects of specific components (e.g. lecithin and minerals) and concentration of β-lactoglobulin (β-Lg) and α-lactalbumin upon thermal and gelation prop...
