AI Technical Summary
Existing wet extraction methods for flaxseed protein suffer from problems such as cumbersome processes, high water consumption, high energy consumption, serious environmental pollution, and damage to protein structure. There is a lack of green dry processes to achieve efficient and environmentally friendly protein extraction.
By employing subcritical extraction for defatting, vacuum drying for moisture adjustment, fine pulverization, and electrostatic separation techniques, combined with appropriate electrode voltage and gas flow rate, a green dry preparation pathway for flaxseed protein was constructed to achieve efficient protein enrichment.
It achieves high efficiency and high quality in flaxseed protein extraction, increasing the protein extraction rate by approximately 20%, while reducing energy consumption and environmental burden, and protecting the natural structure and functional properties of the protein.
