    摘要: 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.

    摘要: There is disclosed a stable animal feed supplement suspension which is prepared by forming a stable liquid gel in concentrated food industry by-products such as by-products of the dairy industry, such as whey permeates, delactosed whey, and by-products of the fermentation industry, such as whey and corn sweet water. These by-products have not been used with any significant success in animal feed supplements, despite their low cost and disposal problems. A major disadvantage is their limited solubility, and the resultant instability of concentrates of the by-products. The invention comprises the treatment of the protein-rich by-products with a mild enzymatic treatment which stabilizes the by-products against protein gelation, and the thermal, and/or enzymatic treatment of the lactose-rich by-products to avoid separation of the lactose from concentrates. The by-products can then be concentrated to high solids content, in excess of 50 weight percent, and the resultant concentrates can be treated with gelation agents, preferably phosphoric acid and lime to form stable liquid gels, to which feed nutrients such as fats, urea, sodium bicarbonate, calcium carbonate, calcium sulfate, etc., or drugs such as monisan, can be added, forming a stable liquid suspension which is useful as an animal feed supplement.
