  • METHOD FOR EXTRACTING ANTIBACTERIAL PEPTIDES AND ALBUMIN FROM PEA WHEY WASTEWATER
    Publication number: 20210276907
    Abstract: The disclosure provides a method for extracting antibacterial peptides and albumin from pea whey wastewater, which includes following steps: in extracting the albumin, centrifuging with the pea whey wastewater generated during pea protein processing as raw material; controlling temperature and exchanging heat to adjust temperature of the raw material; sequentially performing a microfiltrating, nanofiltration, ultrafiltration and secondary nanofiltration to obtain an albumin slurry; performing a multi-effect concentration on the albumin slurry; adding an alkaline substances to adjust pH; sterilizing and drying to finally obtain the albumin, which realizes a targeted extraction of the albumin with small molecular weight in the pea whey wastewater and avoids resource waste. The albumin with small molecular weight and the antibacterial peptides in the pea whey water are effectively recycled, thus avoiding environmental pollution caused by improper treatment of the pea whey water and realizing resource reuse.
