Developing valuable egg components for niche market applications

2016/17-2018/19 • $384,560 • PI,CO
In Canada, about 30% of the total eggs are broken and further incorporated into various food applications; themajority are sold as table eggs. Traditional food uses as above have reached its bottleneck and failed to furtherenhance the profitability of the egg industry. Diversification of egg...

Developing an integrated method of preparing bioactive peptides from spent hens for functional food/nutraceutical and cosmetic applications

Our industry partner is hoping that we can further mature this promising...

Antioxidant peptides in inflammatory and endothelial function

2013/14-2017/18 • $200,000 • PI
In addition to providing sources of amino acids for growth and maintenance, food proteins are recognized as a source of bioactive peptides that could affect human health and reduce the risk of diseases. A putative protective role of antioxidant peptides in cardiovascular diseases has been...

Biopolymer-based nanocomposites from poultry byproducts for packaging applications

2014/15-2016/17 • $72,015 • PI,CO
In recent years, increasing demand for poultry consumption is leading to an oversupply of byproducts such as feathers, skin, and organs. In 2010, Chicken Farmers of Canada processed about 2.34 billion pounds of chicken. In Canada, approximately 22 million spent laying hens are also produced...
