Oyster Mushroom (Pleurotus Ostreatus) Stipe Peptides As In-Vitro Radical Scavenging, Ferrous Iron Chelating, & Ferric Reducing Antioxidant Compounds, Suraj Meharwade
Food Science (MS) Theses
Ferrous iron chelating, ABTS radical scavenging, and ferric reducing antioxidant activity of mushroom stipe peptides obtained using Protamex® and V8 protease has not been investigated. Additionally, the effects of peptides on protein carbonyl formation during myofibrillar oxidation is unknown. Oxidation of lysine, arginine, and proline in myofibrillar protein from red meat results in reduced meat quality owing to changes in water composition. Therefore, the objective of this study was to compare the antioxidant performance of <1 kDa and 1-3 kDa mushroom peptides obtained by Protamex®-V8 hydrolysis against mushroom hydrolysate, mushroom protein, and mushroom stipe for radical scavenging, ferrous chelating, and ferric reducing activity, as well as their effects on protein carbonyl formation within a protein oxidation system. <1 kDa peptides exhibited significantly higher (p < 0.05) in-vitro ferrous iron chelating activity and ABTS radical scavenging activity as compared to mushroom stipe and 1-3 kDa peptides. Whereas, 1-3 kDa peptides demonstrated significantly …

Innovation In Meat Production: A Problem And An Opportunity, Christopher J. Bryant
Animal Sentience
Innovation in meat production has enabled modern humans to inflict far greater harm on animals, the environment, and public health than was possible just a few decades ago. Wiebers & Feigin aptly express the urgency with which these issues must be addressed. Those advocating for animals on moral grounds face resistance from omnivores citing taste, price and convenience. Further innovation in meat production (plant-based and cultured meat) will enable us to preserve the experience of eating meat whilst phasing out the many problems caused by industrial animal farming.
