Total, neutral, and polar lipids of brewing ingredients, by-products and beer: evaluation of antithrombotic activities

摘要

Beer brewing wastes and by-products are a significant environmental challenge but are increasingly being viewed as potential sources of bioactive ingredients. One example is brewer's spent grain (BSG), which used to go to the landfill but is now primarily used for animal feed. The lipid content of BSG is approximately 10.0-13.5% (w/w of BSG samples), and it is estimated that 9.1% of the total lipids are phospholipids.
