Ultimately, these bio-based extraction methods yield functional alternative protein concentrates and rich bioactive compounds designed directly for commercial human food and animal feed formulations.

The ABATE project, coordinated by CERTH in Greece, deploys an advanced bio-based technology matrix to transform residual lignocellulosic biomass into refinery intermediates.

The use of fermented rapeseed meal in animal feed can increase nutritional efficiency compared to soy protein-based feeds. Fermentation allows the protein potential of the meal to be exploited and enriches the feed with short-chain fatty acids, vitamins, and various biologically active compounds. Fermented meal is more readily eaten by pigs and stimulates the pig\'s digestive tract environment to develop beneficial intestinal microflora (Lactobacillus and Bifidobacterum bacteria). Fermentation improves the health safety of feed, eliminates bacteriocins, H2O2, harmful bacteria, and breaks down bitter, anti-nutritional, and toxic substances.
